Fabric Color Fastness to Wash Test Posted on |

Color Fastness: 

           

                 The “color fastness” of a colored textile(Fabric) is defined as its resistance to these changes when subjected to particulates of conditions. It follows that color fastness must be specified in terms of these changes and expressed in terms of the magnitude.

       

       Determination of Color Fastness to Washing:

Method Followed: ISO 105 C06/C08, AATCC: 61

      Required Equipment: Rotawash, Stainless Still Ball, ECE Detergent, Multi-fibre fabric, Grey scale,  Sodium Perborate, TAED.

       Working Procedure:

Collecting the sample from bulk and then conditioning for 04.30 to 06 hours

↓

Making a specimen of 04 cm*10 cm in size.

↓

Sewing the specimen with multi-fibre fabric of same size at one corner.

↓

Making the solution of 4gm/litre ECE detergent & 1 gm/litre sodium perborate, (If required SKFL use 0.15 gm/litre TAED).

↓

Putting the specimen with multi-fibre fabric into the solution in Rotawash m/c

Prog.: C2S       Temp.: 60^OC/ 40^OC             Time: 30 min         Still ball: 25 pcs

↓

Rinsing with hot water respectively.

↓

Squeezing with cold water of the sample is done (Hand Wash).

↓

Then drying is done at a temperature in the air not exceeding 60^OC

       ↓

The stitching is then broken out except on one of the shorter end.

 ↓

Measuring the staining and color change by grey scale & make a test report.
