Compactor Machine | Function of Compactor Machine | Tubular Compactor and Open Width Compactor

Textile Compactor Machine:
Compactor is a textile finishing machine which is designed specially for compacting 100% cotton knitted fabric like jersey, pique, interlock, plush, rib and sinker etc. as well as cotton blended fabric in rope form, changing the loft and dimensional stability of the fabric and presenting it to plaited form. Fitted with two felt compacting units which makes it to obtain top quality fabric, with minimized shrinking nature and a soft fluffy hand.

Function of Compactor Machine:
Compactor is important machine in knit fabric finishing process. There are a lot of technical work which are done by compactor machine. The works are done by compactor machine are pointed out below:

1. GSM control of the knitted fabric. For high GSM, overfeed is increased and fabric width is decreased. For low GSM, overfeed is decreased and fabric width is increased.
2. Control shrinkage
3. Twisting control
4. Increase smoothness of fabric
5. Heat setting is done of fabric etc.

Checking Parameters of Compactor Machine:
Following parameters check in compactor machine.
  1. Shade Check: Shade of the compacting fabric is checked in the delivery side of the machine. The operator collects the fabric and compare the shade of the fabric with the buyer’s approved swatch.
  2. Width Check: Operator measures the width of the fabric with the measuring tape and compares it with the buyer’s requirement.
  3. Weight Check: Weight of the fabric is determined by GSM check. Operator checks the GSM of the fabric by GSM cutter and electric balance.
  4. Edge Line Checking: Two edges of the fabric is check in delivery side. If any fix line is identified, which normally occurs from the expander it should be connected.
  5. Design and Slanting: Operator checks design and slanting of the fabric in the delivery side of the machine.
  6. Fabric Faults: Various types of fabric quality are measured in the delivery side of the fabric.
Types of Compactor Machine:
Compactor machines are two types. They are-
  1. Tubular compactor
  2. Open compactor
Tubular Compactor:
Tubular compactor is used after hydro-extractor, de-watering and dryer. By the compactor machine, compacting is done for control the shrinkage of the fabric. Here, different types of off line quality of the fabric are measured.

Functions of Tubular Compactor: 
Following objectives are achieved by the tubular compactor. They are-
  1. Shrinkage of the fabric is controlled by the compactor.
  2. Fabric width is controlled by the compactor.
  3. GSM of the fabric is adjusted by the compacting.
  4. Fabric smoothness is achieved by the compactor.
  5. Heat setting of fabric for Lycra is done by tubular compactor.
Working Procedure of Tubular Compactor:
The treatment of knit fabrics in tubular form on the Tubular compactor meets the exacting standards set by customers so that garment stitched from the fabric finished on this machine will yield the lowest residual shrinkage values.

1. Width control through a stepless adjustable special tubular fabric spreader driven by variable speed motor for distortion-free fabric guidance.

2. Steamping with a condensate-free steam box which is easily operated and completely made from stainless stell.

3. Compacting through two Nomex felt belts.

4. Calendaring while passing between the felt belt and the heated shrinking rollers.

5. Precision plaiting with automatic platform level adjustment controlled by folded fabric height. Alternatively, a fabric rolling system can be provided.

The fabric is fed through the guiding system and stretcher which then takes the fabric through the steam box onto the felt of the twin compacting units.

At the fabric delivery, the machine is equipped with a precision plaiting device with its platform. The height of the platform is controlled automatically and is adjustable according to the plaited fabric height.

An optical fabric density measuring sensor can provide the means to automatically control the compaction of a tubular compactor to achieve the desired course count. An automatic compaction control system based on density measurement and control will:
  • Eliminate over- and under-weight fabric.
  • Reduce or eliminate punch-weight measurements.
  • Provide consistent results from all operators.
  • Result in uniform fabric, seam-to-seam.
  • Yield predictable residual shrinkage.

Open Width Compactor:
Open compactor is used for compacting the open form fabric. Here, slitting machine is used for open the fabric from the tubular form.

Feature of Open Width Compactor:
Perfect sanforising finishing of knit fabrics.
  1. Ideally suitable for in-line with stenter machines.
  2. Effective shrinkage control
  3. A.C. Inverter drives, PLC with touch screen used.
  4. Equipped with modem connectivity and online troubleshooting system.
  5. Metal detector.
Working Procedure of Open Width Compactor:
Open Width Compactor is suitable for open width knit fabrics to achieve exact dimensional stability and a soft feel. The machine generally consists of a feeding frame with centering device and driven scroll rollers, an equalizing stenter frame with overfeed roller and brush pinning arrangement.

The entry section of Pin Frame is provided with edge spreaders IR In-Feed device, an S.S. fabricated steaming unit for uniform moistening of the fabric. The Steaming Device has stainless steel sliding shutters that allow steam to flow only as per the width of the fabric.

A low contact Glueing and Drying unit is provided with a stainless steel trough. Four selvedge drying units with infra-Red emitters are placed on either side of the machine. The delivery side section consists of edge dryer, Selvedge trimmer and a suction device, Exit roller, Width Adjustment device and the drive to the chain are housed in a exit box.

The compacting unit consists of 2 felt compacting units, each of them consisting of a Nomex felt approx. 20 mm thick, a steam heated chrome-plated center roller of dia. 400 mm, a rubber covered roller driven by variable frequency drive, a compacting pressure roller, a felt tensioning roller and a felt centering roller. Each unit is provided with a special anti-fiction sheet type shoe controlled by an electrical actuator to control the compressive shrinkage. A fabric cooling roller is provided after second felt to cool the fabric by means of chilled water circulation. Fabric Tension through the machine is controlled with the help of sensitive load cells and variable frequency drive with PLC and touch screen.
