Abstract

The invention discloses a proficiency testing sample for measuring the color fastness to perspiration of a textile and a preparation method of the sample. The proficiency testing sample is formed by dyeing a piece of pure cotton weaving tabby bleaching grey cloth by adopting an active dye or a direct dye, the detection result of the color fastness to acidic perspiration (which comprises an original sample discoloration level number, a cotton lining staining level number and a wool lining staining level number) is within 2 level-5 level and contains the daily detection range of the color fastness to acidic perspiration in the field of existing textile clothing, and the proficiency assessment of the detection items of different laboratories or the quality control usage of the laboratories can be realized. The preparation method of the proficiency testing sample has the advantages of easiness and convenience for operation, high success rate and high practicability; the prepared proficiency testing sample can be stored and transported at normal temperature and meets the uniformity and stability assessment guide requirement of a CNAS0GL03 proficiency testing sample in the aspects of uniformity and stability.

Description

technical field [0001] The invention relates to a proficiency verification sample for measuring the color fastness to perspiration of textiles and a preparation method thereof, belonging to the field of light industry textiles. Background technique [0002] Color fastness to perspiration is one of the most basic and important safety technical indicators of textiles. It is the ability of the color of textiles to withstand the action of sweat. Textiles with poor color fastness to perspiration, when people wear and sweat, the dyes in the fabric will fall off and transfer to the skin with the help of sweat, and the dyes may be sensitized and carcinogenic to the human body after being absorbed by the skin serious impact. GB 18401 "National Basic Safety Technical Specifications for Textile Products", EU Eco-Label eco-label, Oeko-Tex eco-label and other domestic and foreign technical regulations have made strict regulations on the color fastness to perspiration of textiles. Color...
