Effect of Acid Cellulase at Different Concentration and Parameters on Wet Processing of Knitted Fabric Part-4

Previous Part

Grey scale for assessing change in shade:

EN ISO 105-A03 / IUF 132 / VESLIC C 1211
This Grey Scale is for assessing the degree of change in shade caused to a dyed Textile fabric / yarn in color fastness tests. For example, the change of shade of wool and cotton fabrics in the wash fastness, perspiration fastness etc. The scale consists of nine pairs of gray color chips each representing a visual difference and contrast.

The fastness rating goes step-wise from:
Note 5 = no visual change (best rating) to Note 1 = a large visual change (worst rating).

The gray scale has the 9 possible values:
5, 4-5, 4, 3-4, 3, 2-3, 2, 1-2, 1.

It is now quite common to measure the Grey Scale change in color instrumentally. This is made using a suitable reflectance spectrophotometer according to the test method procedure, EN ISO 105-A05.

Grey scale for assessing staining:

EN ISO 105-A03 / IUF 132 / VESLIC C 1211
This Grey Scale is for assessing the degree of staining caused by a dyed Textile / yarn in color fastness tests. For example,the staining of wool and cotton fabrics in the wash fastness, perspiration fastness, etc. The scale consists of nine pairs of gray color chips each representing a visual difference and contrast.

The fastness rating goes step-wise from:
Note 5 = no visual change (best rating) to Note 1 = a large visual change (worst rating).

The grey scale has the 9 possible values:
5, 4-5, 4, 3-4, 3, 2-3, 2, 1-2, 1.

It is now quite common to measure the Grey Scale for assessing staining instrumentally. This is made using a suitable reflectance spectrophotometer according to the test method procedure, EN ISO 105-A04.

CIE L* a* b* DATA OBSERVATION:

DISCUSSION:
  1. If concentration of acid cellulase increase then brightness also increase.
  2. If concentration of acid cellulase increase then whiteness also increase.
  3. If concentration of acid cellulase increase then yellowness decrease.
CONCLUSION:
Thus the “Enzyme” replaces traditional method with more advantage such as-
  • Replace harmful chemical.
  • Require less effluent treatment
  • Low cost and less energy consumption.
  • No damages to material.
LIMITATIONS:
  1. We have less time to complete the work so we could not narrate our research deeply.
  2. More shortage of raw material & chemical.
  3. We does not got proper help for the Industries so we could not implement our research practically.
  4. Economic bound us within great limitation
