  testing method:

 

　　The color fastness to washing test is to sew a white cloth on the sample, put it in a washing solution at a certain temperature, and immerse and wash it for a specified time under mechanical agitation. Due to the variety of washing methods and washing liquids, the test result is an indicator with strict condition value meaning.

 

　　 The main factors that affect the test results are as follows: temperature, stained white cloth, liquid volume, stainless steel ball, time and the order of the interaction of stainless steel ball in the method of effect on fading. Among them, temperature has the greatest influence, and the factors behind the stained white cloth have little influence. In terms of influencing the stained white cloth, the order of importance is: the stained white cloth, temperature, sodium carbonate, liquid volume, time, and the interaction of the stainless steel ball. Among them, the influence of stained white cloth is the biggest, and the influence of temperature is also great, and the two factors of time and stainless steel balls have almost no influence. Because of this, when testing, different test temperatures should be selected for samples of different fiber types.

 

　　The temperature is determined mainly in accordance with the applicable standards: GB/T3921.1～3921.5, ISO105 C01-C05 "Textile color fastness test and washing color fastness test 1～test 5"
