Abstract

The invention discloses a method for testing color fastness (light / chlorinated water composite color fastness) of textiles. The method comprises the following technical processes: immersing fabric into available-chlorine chlorinated water with a concentration of 20 mg / L for 30 min, enabling the fabric to absorb the liquid completely, controlling a mangle expression of the fabric, and enabling a liquid rate of the fabric to be 100%; and performing a light fastness test under an illumination condition with an irradiation amount of 85 KJ / m <2>.nm, and determining the performance of light / chlorinated water composite color fastness of the fabric according to sample color-change situations. According to the method disclosed by the invention, the influences on the color fastness of the textiles from the chlorinated water and illumination are comprehensively considered, and a stage test method comprising the steps of immersing by the chlorinated water and performing the light fastness test is adopted, so that the limited situation that the color fastness standard at home and aboard is only determined by light color fastness or chlorinated water color fastness is broken through.

Description

technical field [0001] The invention relates to a method for testing the composite color fastness of textiles to light and chlorinated water. Specifically, it is a method for evaluating the light resistance of textiles determined through a series of experiments by comprehensively considering the effects of light and chlorinated water on the color fastness of textiles. , An effective test method for the comprehensive effect of chlorinated water. Background technique [0002] Color fastness refers to the resistance of the color of textiles to various effects during processing and use. The fundamental reason for the poor color fastness of fabrics is that dyes are affected by external factors and are destroyed to cause changes in chromophoric groups. Poor color fastness directly affects the appearance of fabrics and clothing, and the decomposed dyes are likely to have adverse effects on the human body during contact with the skin. Countries all over the world have long recogni...
