Washing Machine

Ø  Work: Color fastness to wash.

Ø  Subject: Color fastness to washing is the common quality parameter, which is considered very important from the point of view of consumers. This test determines the loss & change of color in the washing process by a consumer and the possible staining of other garments or lighter portion that may be washed with it.

Ø  Machine configuration & equipment:

v  Wash wheel

v  Standard reference detergents without Optical Brighteners – either ECE or AATCC

1993 as specified by the standards.

v  Multfibre Fabric

v  Stainless Steel Balls

v  Grade 3 Water

v  Washing pot

                                    Different parts of the M/C

Test Equipment

                                Work Stapes

ü  Sample are cut either in 4 x 10 cm size (ISO) or 5 x 10 cm for AATCC 61 1A or 5 x 15

            cm for other AATCC 61 methods.

ü  Sample and multifibre attach by stitch.

ü  Temperature rate will be 1.5⁰C / min

ü  A wash liquor is prepared using Grade 3 water( with 40⁰C), the appropriate detergent and additives. The detergents that are specified are the ECE standard reference

           detergent WOB and AATCC Standard Reference Detergent 1993 WOB.

ü  The Sample + multifibre is placed in the wash wheel pot(M/C temperature will 40^0C) containing wash liquor,

            with additives and steel balls as may be required. The wash wheel is then run for the

            appropriate time duration.

ü  After unload this will be wash at 40⁰C in 100 ml normal water for 1 Min for two times.

ü  The Sample + multifibre dried in still air at temperatures not exceeding

            60°C. Once dry and conditioned, assessment is carried out.

ü  When yarn of fibres are to be tested yarn/fibre weight and multifabric weight well be equal.

               Assessment / Results and Interpretation

ü  Change in shade – loss of colour or tone as compared to the original unwashed

Sample.

Test result :

Gradeing by grey scale or data color (Spectrum)

Grades :

5 – Very good

4 – Good

3 –Fair

2 –Modarote

1 –Poor

0 –Very poor

Grade 3 will be allowed but lower than are not allowed
