Do you know what is the working hour for a merchandiser in Bangladesh . Believe or not Merchandisers in Bangladesh are working more than 13-14 hours as regular job & some time much more . Always they are busy with hundreds of work schedule but nothing can be completed within office hour . So they have to stay in work place up-to late night . You can’t say this is only inefficiency of their profession because most of the time they are over loaded . The owners are having a cost minimizing tendency so they hire a Merchandiser instead of two or more without considering the demand of work load . As a result a merchandiser always fail to enjoy their regular life & gets tired . They loss their innovative force & feel exhausted in older years . We often see merchandiser who aged beyond 45-50 either loss their job or stay in the organization as a good for nothing . Owners don’t want to pay higher salary for him though they already have taken valuable energy ,time & work force in early age . This is really shocking that now they feel you are not to be used . Yes , right now we have to think how can take the best from our life period . Whatever the age we should have to keep energy & not to be exhausted . We can think for us from today & prepare a new deal for your career . To make easy & to be smarter merchandiser in our way of working please let us do something different . Today we are going to discuss how you can manage your thousands of job in a limited period of hours & can keep maximum energy .
Merchandiser work in office
Merchandiser work in office
1) Make a list of all your job:
This is very important what you are doing to keep it in your daily schedule . It would be better to make schedule 1st daily than weekly & finally monthly . Why this is important to do list ? First of all we are human being. So this is not possible to keep everything in our mind & to do the thing in priority basis . Usually a Merchandiser has to work through lots of stress as well as difficulties . For which this is not surprising if you see he is forgetting to do some most important task that should have to perform in first priority . The second thing is – when we see thousands of task that we have to perform within a very short period of time our nerves gets week . we feel exhausted & fatigue . So by the making schedule we can easily prioritize your task & get the most important & urgent thing .

The below diagram will help everyone to do list in the work priority . This may take little time to make your habit with the method but believe me the method is really effective .

Not Urgent
  1. Fabric booking
  2. Yarn procurement
  3. Price for new query
  4. PP sample submission
  1. Recape meeting with senior
  2. Production up-date
  3. Bulk Lot shade approval
  4. Factory visit & get the production status
Not Important
  1. File & Sample organizing
  2. System Up-date
  3. Price review
  1. New product collection
  2. Develop product knowledge
  3. Knowing up-date product status of other customer
2) Don’t put task for tomorrow:
Just keep in mind that tomorrow never come . If you are thinking today is for relax & tomorrow will be your busy day that would be unrealistic . Actually it does not happen because tomorrow you will see new task has added to do & in this way task will be more . One day without doing your important task means you are going to burden yourself for tomorrow .So whatever you think that should have be done today from your task priority list , do it immediately . Never wait for tomorrow.

3) Check double/Triple which is mathematical:
Usually a merchandiser works in a rush movement so sometimes it is not possible to do all the mathematical task in cool mind . Suppose you are going to book fabric or yarn . Here you have to calculate some figure to get the fabric amount that can be used for bulk . but for the all rush movement you made little mistake & proceeded for procurement . Your delivery time may be very short so without any revision of your booking hand over it to supplier & finally when the fabric in-housed it was identified what mistake you have done earlier during fabric booking. May be you mistake in color name or fabrication is wrong . Instead of 90/10 cotton/elastane you received fabric in 100% cotton . This is due to you worked in an old work order sheet where fabric was booked in 100% cotton & in the new sheet fabrication was not changed . The mistake is very little but outcome is devastating . To save time you did not give a cross check on the sheet & now all of your production schedule has gone to drain . This is really measurable when you will see your fabric is in-housed but cannot meet delivery date . Now again book the fabric newly & shipped the goods by air due to you missed delivery date . Actually this would not happen if you are careful & taking extra time give revision twice or triple . If you can take help from your colleague to see the booking as second party . This will help you to avoid extra hassle & to utilize your time properly . Here you can keep some key for cross check . cross check means the figure that should be off course changed in new booking . For fabric booking check the below
  • Fabric composition .
  • Fabric construction .
  • Fabric color .
  • Fabric width .
  • Finally Fabric Qty .
4) Don’t miss any mail:
A single mail can change total output . If you are not properly look into your mail & work through of it you may miss some important information . So read your every single mail & share the mail with all the relevant party . Don’t keep it in your box only . If you have some mail that you should give answer please keep it in red mark so that it will not go out of your track .

5) Don’t do a task twice:
This is actually relevant to point no 3 . Take extra time to do anything but don’t think you will do it twice or 2nd time you will get the opportunity to do it again . Suppose you are in great rush hour to submit sample, giving mail repeatedly to factory to submit the sample in certain date along with lots of phone call . Finally received it but factory made mistake to follow earlier comments what buyer has given . That means the sample is rejected & is not ok to send buyer . Again the sample is made following the comments but it was late one week . So all your production plan got delayed because of not to submit the sample due date . Actually from beginning you could avoid all the delay & wrong thing . If you could take just extra 15 minutes to check the change that buyer want in the earlier comment or before stitching you could visit factory & check everything that sample is going in right way it would help you to save time & energy . Take extra minute to do anything .

5) Do extra work just one day:
In your ‘to do list’ you got some task that has to be done by this week but you are engaged so much in some important meeting so could not able to work on weekly schedule . Now what can you do ? Use only one day to work extra hour in the week . Never think to do it every day . You can work extra hour at the last working day of a week so that the next day you can do relax & enjoy family . So a day for a week can be your extra hour to finish pending task . This will help you to minimize your work load .

6) Make a good relation with everyone to get job done early:
This is said that everyone is king in his own work place . May be the person is a lab in charge . As job routine he is bound to do what are all your requirement because owner assigned him to do job what merchandiser demand in related to lab issue . But this is also true he keeps schedule in his every day to do list as per queue . So you cannot ask for lab dip just in a day where as he has hundreds of lab making in the schedule . Here if you have good relation with the person it will be easy to get lab dip though you are not in the queue . So make a good relation to all the department even a person who is in a worker level . Never underestimate any one . Respect all to get respect from every one .

7) Utilize down time:
Usually success comes from the time which is not usually counted by the commners . Because to do extra work there are no alternative way except utilizing down time . Down time means – the time what you are just doing nothing or doing one more job simultaneously . Suppose you are just stucked in the traffic jam which is very common in our city life . It is often seen people are just seating in the jam & trying to blame the system . But if you want to use your down time ,this can be an opportunity for you . Take journal or book & start reading . That means all of your time can be used properly . On the other hand you can use down time in different way . May be you are having lunch .This may take 15 minutes to finish . During your lunch time you can listen radio news in your mobile . This will help you to get up-date information about what is happening around you . your busy life will not stop you to be up-dated in a new day .

8) Keep proper tracking whatever your are doing:
We are human being . So sometime this is not possible to keep everything in our memory . In the merchandising no one can you say everything is in tracking unless he follows some basic rules . The basic rules of keeping track is ‘put down notes’ in your excel sheet or note book . Make a excel sheet & put all your information whatever you receive every day . Put the date on the stuff what you receive from buyer & what you send to buyer . keep same information on the submitted items to avoid any kinds of confusion between you & buyer . Keep your sample / swatch in a place where anything may not be lost . Make sure to keep separately all your important items to be understood by everyone or to get it in your absence . You can follow below rules to keep tracking .
  • Put date on everything .
  • Up-date & review your excel sheet every day .
  • Keep hard copy of all your important mail . Because some time you may not be in net service when the information is required .
  • Put your excel saved in your draft mail to find the data available incase computer is got effected by the harmful virus .
  • Don’t forget to send a mail to any consignee whenever you are sending sample /swatch .
9) Keep all approval in hand :
Don’t miss any of your approval that received from buyer . Suppose fabric quality , sample or trims whatever comments on submission please keep in proper way so that it will not loss . If you have several submission on particular item that sent to buyer make sure to keep date & comment for each submission . This will help you not to be haphazard among the all submission .

10) Don’t miss to put anything on mailing correspondence :
Some time you may feel unnecessary to put things in the mail whatever discussion you did in phone or verbal communication with someone . In reality this is very important & never delay to put the content you discussed in a written document /mail to prove the conversation . Suppose a trim supplier confirmed you in a particular date to deliver the item over the phone . As you feel the commitment is definitely will be met so did not put the conversation in mail . But in the due date you get the supplier denied to deliver the item & ignored his commitment . So if you could keep the commitment in a written document it would be easier to hold him . Believe me this is most effective to make easy your job ,keeping things in mail .

11) Keep clean your desk :
A merchandiser has to do hundreds of job in a day so this is quite natural if his desk gets occupied by lots of stuff like paper , swatch , trims etc. Every day new items come to you & your surrounding is seeming a little store of fabric , sample & with others thing . You feel over loaded as your desk is overloaded by working stuff . How can you clean your desk to make free from all kinds dizzy materials ? This is really challenging for you rather than your daily job . Some time we feel keeping things on desk is not a problem & this is actually to get the things in hand . Believe me if your boss or others want to see anything in your obscene from the desk they might be puzzled & confused what to take & what to not take . So use only 30 minutes to keep clean your desk & put all the stuff in particular folder so that anyone can find any important item . This will make your job easy . Remember ‘The true competition lies is not what we do, but how we do it’.

12) Take suggestion if you are in trouble :
The universal truth is – two head is better than one head . That means if you are trying to do something counsel with other so that you can work more efficiently with less error . Never think you are the perfect one & no need to take suggestion from others . In other way this is called – cheer leader .Cheer leader is your boss , co-worker , friend so If you want to be in track & to do the correctly must discuss with fellow people. Definitely this will ease your job .

13) Filing & updating :
A merchandiser means lots of file & documents, so maintaining file for the each order & keeping the necessary stuff is very important . Actually this is little similar to the point ‘Keep clean your desk’. However this is specifically to put the thing in file properly . How your file will look ? where to keep it ? what name can be given to each file ? there are lots of issue that should have to take in consideration if are really interested to be a smarter merchandiser . To do your task in smart way you need to think about your file . Suppose where to keep it ? always try to keep your important file close to your hand so that you might not be haphazardly looking for your file when you need . Here some suggestion how to keep file –
  • Put a name for your file in bold letter .
  • Put all the information on top of the file ,example – style name , PO no , Qty , & a garment sketch .
  • Your file should be clean & need to keep all the paper in a chronological way .
  • For easy understanding you can use divider to keep separate the subject matter .
  • Use folder to keep different submission ,off course don’t forget to write date .
  • Use metal cliff so that the file can be use for long time .
  • If you receive revised PO please make sure to keep it in file & keep a cross mark on old PO .
  • Never remove any paper from your file ,if Pos are revised keep date on old file & write on top of it why this is changed .

(1) To calculate the number of machine necessary for daily production quantity in each process.

The number of machines necessary for each process,
      Time for each process X daily production quantity
                          Work time per day

Example: For dirt sewing
  • Process time …………………………..0.76 min.
  • Work time per shift …………………480 min.
  • Production quantity per shift….400 pcs.
                                                                                                 0.76 X 400
So, The number of machines necessary for each process = …………………

The number machine necessary for sewing dirts = 0.63 = 1 machine (ANS)

(2) The number of the machine you need will be calculated by applying the value obtained in (1) to the configuration (process composition).

In each park and each kind of machine. When you establish process composition, consideration to the layout which allows the works in process to run smoothly between lines must be taken.

(3) Calculation method of the number of the required machine according to the different of production quantity per shift or the number of persons

The number of required machine should be originally calculated in the way as above-stated in (1).

But there is a simplified calculation method by using MACHNE LIST and BASIC DATA described in this document.

(4) Calculation method of the number of required machines according to the difference of production quantity per shift

The number of required machine,
                                                  Production quantity per shift after change
= The number of each machine X ………………………………................
                                                         Production quantity per shift

  • The number of DDL-555ON-7 –WB/CP230/AK-85…………………8 machines
  • Production quantity per shift …………………………………………200 pcs.
  • Production quantity per shift after change…………………………….120 pcs.
                                                                           120 pcs
The number of required machine = 8 machine X …………
                                                                           200 pcs

= 4.8 = 5 machine (ANS)

(5) Calculation method of the number of required machine according to the difference of persons                          
The number of required machine,
                                                 The machine of persons per shift after change 
= The number of each machine X ……………………………….....................
                                                             The number of person

  • The number of DDL-555ON-7-WB/CP230/AK-85 …………8 machines
  • Number of persons per shift ………….………………….45 persons
  • Number of persons per shift after change……………………100 persons
                                                                            100 persons
The number of required machines = 8 machine X ……………
                                                                             45 persons

= 17.7 = 18 machines (ANS)

(6) Calculation method of the production quantity per year according to the different of work days per year.  The production quantity per year is calculated on the basis of 280 days per year in this document. When the number of work days per year is different, use the following formula to obtain the production per year.

The production quantity per year,
                                      Work days per year after change 
= Production per year X ………………………….....…......
                                                    280 days

  • Production quantity per year …………………..……………56,000 PCS.
  • Work days per year after change ……………………………250 days
                                                                              250 days
The production quantity per year = 56,000 pcs. X ……………..
                                                                             280 days

= 50,000 pcs . (ANS)

(7) Method of the number of persons according to the difference of production quantity per shift

                                                                      Production quantity per shift after change
The number of persons = Number of persons X …………………………………............
                                                                          Production quantity per shift

  • The number of persons ……………………………..45 Persons
  • Production quantity per shift …………………….500 pcs.
  • Production quantity per shift after change ………………………850 pcs.
                                                              850 pcs.
The number of persons = 45 persons X …………
                                                              500 pcs.

= 76.5 = 77 persons (ANS)

(8) Calculation method of production quantity per shift according to the different of the number of persons

From (formula 2),

Production quantity per shift,
                                                The number of persons after change 
 = Production quantity per shift X …………………………………........
                                                     The number of persons

  • Production quantity per shift in BASIC DATA ……….........500 pcs.
  • The number of persons in BASIC DATA ……………………….75 persons
  • The number of person after change ……………………………100 persons
                                                                            100 persons
The production quantity per shift = 500 pcs. X ……………………
                                                                            75 persons

= 666.7 =  666 pcs. (ANS)

(9) Simplified calculation method of the required floor space according to the difference of total number of required equipment

The required floor space = (required floor space per 1 finishing equipment X total number of sewing equipment) + (required floor space per 1 finishing equipment X total number of finishing equipment)

  • Required floor space per 1 sewing equipment …………..about 6 m2
  • Total number of sewing equipment ……………………………187 machines
  • Required floor space per 1 finishing equipment …………about 10 m2
  • Total number of finishing equipment ………………………….20 machines
Required floor space, 
= (6 m2 /1 machine X 187 machine) + (10 m2 /1 machine X 20 machines)

= 1,322 m2 (ANS)

3.2 Smart Breathable Fabrics
Smart Fabrics and Interactive Textiles are defined as having an in-built ability to respond to external stimuli, including electrical, mechanical, thermal, chemical or magnetic. Current smart textile systems aiming to reduce the discomfort caused by moving between hot and cold environments generally rely on temperature as a stimulus [20]. Temperature sensitive polymers can be used in membranes and coatings in combination with fabric which gives waterproof breathability in which WVP changes with change in temperature. To design fabrics which can use humidity as a trigger to react to changes in the micro-climate in order to keep the wearer dryer for longer and get dry quicker can be more comfortable to wear [11].

3.2.1 TS-PU (Temperature Sensitive Polyurethane)
Temperature-sensitive polyurethane (TS-PU) is one novel type of smart polymer. The water vapour permeability (WVP) of its membrane could undergo a significant increase as temperature increases within a predetermined temperature range. Such smart textiles would not only be waterproof at any temperature, but also provide variable breathability in response to the climate temperature [17].

3.2.2 Temperature-Sensitive Copolymer
A smart breathable cotton fabrics using a temperature-sensitive copolymer - poly (N-tertbutylacrylamide-ran-acrylamide:: 27: 73) was developed by Save et al.

Recipe Used:
  • Copolymer(aq.) -20 wt%
  • 1,2,3,4-butanetetracarboxylic acid (cross-linker)-50 mol%
  • Sodium hypophosphite (catalyst)-0.5 wt%
Followed by drying (120°C, 5 min) and curing (200°C, 5 min).

The coatings after integration to the cotton substrate retained temperature-sensitive swelling behaviour and showed a transition in the temperature range of 15-40°C. The coated fabrics showed a temperature-responsive water vapour transmission rate (WVTR) [6].

3.2.3 HPMC
Hydroxypropyl methyl cellulose (HPMC) is an intensively investigated temperature-sensitive polymer which has a simultaneously hydrophilic and hydrophobic structure and demonstrates a low critical solution temperature (LCST) at about 55.65 °C. In an aqueous solution, the macromolecular chains of HPMC experience reversible solubility and exhibit a significant hydration-dehydration change in response to temperature stimulus. These polymers have both hydrophilic and hydrophobic groups in their structure. Below LCST, the hydrophilic interactions dominate and polymer becomes soluble in water, while above this temperature hydrophobic interactions dominate and polymer becomes insoluble in water. The gel change shape by swelling in water below transition temperature and de-swells above transition temperature [17].

The temperature responsive smart breathable behaviour of the HPMC coated fabric was studied in a recent research.
DSC Curve for HPMC Polymer
Recipe Used:
  • HPMC(aq.) -10 wt%
  • Citric acid(cross-linker)-5 wt%
  • Sodium carbonate (catalyst)-0.5 wt%
And then followed by drying and curing.

The coatings after integration to the cotton substrate retained temperature-sensitive swelling behaviour and showed a transition in the temperature range of 30-40°C.The coated fabric is exposed to external temperature, it will display swelling/shrinkage or hydration/dehydration properties, and cause changes in the water vapour transmission rates (WVTR), permeance and permeability of the fabrics [17].

3.3 Fabrics based on Biomimetics
Biomimicry or biomimetics- is a new way to think of how we may be producing new materials in the future. Biomimicry is derived from the Greek word „bio‟ –meaning life and „mimetic‟ meaning „mimic.‟ Biomimetics is the science of applying nature's principles to human engineering and design [19]. Biomimetics is the mimicking of biological mechanisms, with modification, to produce useful artificial items [2]. And biomimetics clothes are those which mimic the wonders of biological world and perform more effectively

3.3.1 The Pine Cone Effect
Humidity-responsive adaptive textiles respond to levels of humidity in the micro-climate, so that breathability improves as the material begins to saturate [18]. The fabrics based on pine cone can be used for a more effective waterproof breathability. Pine cone opens and closes its spines according to the weather, If it's going to rain, the spines close up to protect the seeds inside and if it's going to stay dry, the spines open up to improve the chances of the seeds escaping [13]. Researchers at England's Bath University and the London College of Fashion are trying to design biomimetics clothes that could work the same way. The fabric could be made with an outer layer of tiny spikes, only 1/200th of a millimetre wide. When it's hot, the spikes would open up to let out the heat, cooling you down. When it's cold, the spikes would flatten back down to trap air and provide more effective insulation [13].
Open Spines of a Pine Cone
Closed Spines of a Pine Cone
Nike introduced similar concept to produce its „Macro React‟ range with a Fish-scale Pattern. It was first worn by tennis star Maria Sharapova at US Open 2006 and later by Roger Federer at Wimbledon.
When someone wear this clothing, upon perspiration, the flaps in the fabric swings open to release heat and moisture to keep one dry and cool. The same clothing is made way for golf dresses [16].
Also the introduction of INOTEK Fibres developed by MMT Textiles, which works on pine cone effect, has brought a new revolution in the field of waterproof breathability. The fibres alleviate the feeling of dampness by increasing the permeability of yarns and textiles as moisture builds up around them. The manufacturers in the field of sports clothing, base layers, underwear, socks and bedding fabrics can bring new products that has improved comfort which can be delivered by keeping them dryer for longer and getting them dry quicker in extreme conditions. The U.S. Army Natick Soldier Research, Development and Engineering Centre in Massachusetts have tested a range of textiles using INOTEK patented fibres and validated all the resulting data. They verified its performance via a series of tests carried out on 100% INOTEK fibres, its blend with natural fibres like Merino wool and commercial fibres like Tencel, all the test samples showed significantly improvement in permeability at 98% Rh against relevant test and control samples. The breathability of INOTEK textiles improves gradually from the first point of elevated relative humidity up to optimum performance at the point of saturation [20].

INOTEK fibres work just opposite to the wool fibres. As the material starts absorbing moisture the fibres start to close (mimicking the pine cone) and reduce in volume causing yarn to thin three-dimensionally in the cross-section. Microscopic air pockets are opened in the material and this increases its breathability. In contrast to pure wool, an INOTEK/wool blended yarn can reduce its thickness by up to 10% of its original width in damp conditions. The reactive response to humidity is also reversible. INOTEK fibres revert back to their original state in dry conditions, reducing air permeability and increasing insulation of the textile as in case of pine cone[20].

INOTEK fibres can find application not only in apparel sector but also in health and hygiene sector such as bedding, where more efficient moisture management would be of huge benefit and wound dressing, where this unique breathable technology could control moisture levels beneath the dressing, enhancing comfort whilst offering the same level of protection from infection etc [20].

3.3.2 Transpiration within a Leaf Effect
Transpiration is a process that involves loss of water vapour through the stomata of plants. The loss of water vapour from the plant cools down the plant when the weather is very hot. When the plant loses water through transpiration from the leaves, water from the stem and roots moves upward, or is `pulled', into the leaves.

AZKO NOBEL’s Stomatex
The clothing is made of neoprene fabric along with foam insulation which has tiny hole like dome, as like the transpiration process within a leaf, which provides a controlled release of water vapour to make the clothing comfortable. Stomatex is claimed to respond to the level of activity by pumping faster as more heat is produced, returning to a more passive state when the wearer is at rest. Stomatex is used in conjunction with Sympatex, Akzo Nobel‟s waterproof breathable membrane, to produce a breathable waterproof insulating barrier for use in clothing and footwear. The manufacturer claimed it as „the most comfortable clothing and footwear systems in the world today‟ [2] [12] [16].
4. Conclusion:
The technology has witnessed significant developments in the field of waterproof breathable fabrics in recent times from bi-components to smart breathable fabrics including biomimetic clothes and there is a long way to go in the future. The development of INOTEK fibres has brought a revolution in the field as they will improve the standard of products in quality and functionality. Among all the products being used in this field the biomimetic clothing can be proved best effective.The scopes are unlimited and resources are infinite. Any change in the technology and methods can lead to the development in the field of Waterproof Breathable Fabrics which can be used effectively and efficiently in near future.
