Problems solved by technology

Through search and novelty search, there are not many literatures in the prior art on "testing of color fastness of textiles" and proficiency testing, and only one related document "On the Testing of Color Fastness to Perspiration of Textiles" mentions and approves it. The Commission organized a "CNALT0180 Textile Color Fastness to Perspiration" proficiency verification program in 2004, but its content was mainly aimed at laboratory testing, and it had no reference significance for the preparation of laboratory samples for testing textile color fastness to rubbing

Abstract

The invention discloses a capability verification sample for detection of textile color fastness to rubbing and a preparation method thereof. The capability verification sample is prepared by reactive dye or direct dye-based dying of pure cotton woven plain or twill bleached grey cloth. A test according to GB / T3920-2008 textile color fastness and color fastness to rubbing proves that color fastness to dry rubbing and color fastness to wet rubbing are in a range of 2-5 level, the existing daily detection range of color fastness to rubbing in the textile and clothing field is covered, and capability evaluation of different laboratory detection projects or laboratory quality control use is realized. The preparation method of the capability verification sample has simple processes, a high yield and high practicality. The capability verification sample can be stored and transported at a normal temperature and has uniformity and stability according with the CNAS-GL03 capability verification sample uniformity and stability evaluation guide requirements.

Description

technical field [0001] The invention relates to a proficiency verification sample and a preparation method for testing the color fastness to rubbing of textiles, which belong to the field of light textiles. Background technique [0002] The color fastness to rubbing of textiles reflects the ability of the dyeing fastness of textiles to withstand mechanical friction. For textiles with poor color fastness to rubbing, the dyes in the fabric will fall off due to friction and die when people wear or use them. Transferred to the skin, the dye may be carcinogenic and sensitizing to the human body after being absorbed by the skin. In recent years, in domestic and foreign textile supervision and spot checks, the unqualified rate of this item is relatively high. The color fastness to rubbing of textiles is a routine testing item in textile, furniture and building materials laboratories, and it is also one of the most basic and important safety technical indicators for textiles.
