Abstract:ISO 105-C03: ISO 105

establishes Test No. 3 of a series of five washing tests. A specimen of the textile, in contact with one or two specified adjacent fabrics, is mechanically agitated under outlined conditions of time and temperature in a soap solution, then rinsed and dried. The change in color of the specimen and the staining of the adjacent fabric(s) are assessed with the grey scales.

The color loss and staining resulting from desorption and/or abrasive action in one single (S) test closely approximates to one commercial or domestic laundering. The results of one multiple (M) test may in some cases be approximated by the results of up to five domestic or commercial launderings at temperatures not exceeding 70 °C. The M tests are more severe than the S tests because of an increase in mechanical action.

These methods do not reflect the effect of optical brighteners present in commercial washing products. These methods are designed for the detergents and bleach systems given. Other detergents and bleach systems may require different conditions and levels of ingredients.

Introduction The test methods in this part of

ISO 105 are intended to reflect the effect of washing using soap or soap and soda by domestic and commercial laundering procedures on the color of textiles.

In this Test, a Specimen of Textile in contact with pieces of Adjacent Fabric (Standard Fabric) is mechanically agitated in a Standard Soap Solution (Sodium Oleate Solution), before being rinsed and dried. The change in Color of the Specimen and the Staining of the Standard Fabric are assessed with Standard Grey Scales. The Instrument used for this purpose is called Digital Washing Fastness Tester.

The temperatures for different tests are:

ISO-105-C01=40 °CISO-105-C02=50 °CISO-105-C03=60 °CISO-105-C04=95 °C

Principle A specimen of the textile in

contact with one or two specified adjacent fabrics is mechanically agitated under specified conditions of time and temperature in a soap, or soap and soda solution, then rinsed and dried. The change in color of the specimen and the staining of the adjacent fabric, or fabrics, are assessed with reference to the original fabric, either with the grey scales or instrumentally.

ApparatusSuitable mechanical laundering

device, Balance, mechanical stirrer, The LABIN Digital Washing Fastness Tester is supplied complete with:

1. Main Bath (Made of Stainless Steel).2. 8 Nos Die Made Stainless Steel Test Vessels (Jars).3. 100 Nos Non-Corrodible Steel Balls.

Reagents and materials

Procedure Specimen 10 cm × 4 cm dyed fabric is taken and half is sandwiched between

another 10 cm × 4 cm bleached fabric and bleached sample is sewn on to the dyed fabric sample along all four sides.

The soap solution according to the test used is made. This tester consists of a thermostatically controlled, electrically heated water

bath made of stainless steel. The composite specimen is placed in the container together with the

specified number of steel balls. The necessary amount of soap solution is added preheated to the test

temperature 60 °C ± 2 °C. The container is closed and the machine is operated at the 60 °C

temperature and for 30 minute. Time is noted as soon as the container is closed.

For all tests, remove the composite specimen at the end of the wash and place it in a 4 l beaker half filled with grade 3 water at ambient temperature. Gently agitate, rinse for 1 min and then the beaker is placed under a cold running tap for 1 min.

For all methods, extract the excess water from the composite specimen by squeezing the test specimen by hand.

The composite specimen is Open out by cutting the stitching except on one of the shorter sides if necessary.

The specimen is dried by pressing it flat between new filter papers to remove excess water. Then dried by hanging it in the air at a temperature not exceeding 60 °C, with the parts in contact only at the line of stitching.

The change in color of the specimen is calculated and the staining of the adjacent fabric with reference to the original s specimen using either the grey scales or instrumentally.

Calculations:Evaluation: Change of color of the original color sample (color change) and the color of originally white sample (color transfer - staining)Two possible principles: Measurement of color difference (not so common) and using of color-difference standards “gray scales“(standard evaluation)Grey scale: One for „color change „ testing and the second one for the “staining“.
