The principle and standard analysis of washing color fastness tester for testing experiments

The

Washing Fastness Tester is mainly used to test the color fastness of textiles during washing. Textile color fastness refers to the ability of textile colors to withstand various washes. An important indicator for measuring the use value of textiles. This article mainly analyzes the difference between the color fastness test standard GB/T3921-2008 \"Color fastness of textiles to soaping\" and the standard GB/T 12490-2007 \"Color fastness test of textiles to household washing and commercial \". Similarities and differences, as well as selection advice for related textile color fastness testing technologies.

1. Principle
Sew the textile sample with one or two specified pieces of backing fabric, put it in a soap solution or a mixture of soap and anhydrous sodium carbonate, and wait for the specified time and temperature, subjectedFirst use mechanical agitation, then rinse and dry and use a sample card or gray instrument to assess the sample for discoloration and staining of the lining fabric.

2. Comparison of standards
Test standards for color fastness to washing: At present, my country\'s standard for color fastness to washing of textiles is GB/T3921-2008 \"Color fastness to textiles and color fastness to soaping” 》 is a revision of GB/T3921.1-5-1997 and will be officially implemented on December 1, 2008. The new standard integrates the five parts of the old standard and makes modifications and adjustments in aspects such as coating selection, combined sample cleaning and evaluation methods. . The amendment to this standard adopts ISO105-C10:2006 “Color fastness testing of textiles, part C10: Color fastness to washing with soap or after-sales serviceon and liquid soda.” This is a small, rapid test method for predicting the color fastness of textiles to washing in the laboratory. There are 5 washing methods, from gentle to vigorous, and the test temperature is 40-95°C.
