Embodiment 1

[0074] Cotton cloth color fastness graded standard sample, the color fastness to water of the standard sample is graded 4 to 5 as it is for discoloration, 2 to 4 for cotton lining, and 2 to 4 for wool lining. The numbers range from 3 to 5. The specific preparation method is as follows:

[0075] 1) Gray cloth: Choose pure cotton woven plain gray cloth with relatively flat surface and less surface defects. The parameters of the gray cloth are: warp density 86 threads / inch, weft density 60 threads / inch, warp and weft yarn count 40Ne, square meter weight 100g / ㎡, width 90cm.

[0076] 2) Pretreatment: raw fabric preparation, singeing, desizing, scouring, bleaching;

[0077] Singeing: Gas singeing machine is adopted, and the technological process is: cloth feeding → brushing → singeing → fire extinguishing → cloth falling, and the singeing series reaches 3-4 levels.

[0078] Pre-treatment process of annealing, boiling and bleaching: the one-bath pre-treatment process of alkali oxy...

Abstract

The invention discloses a cotton cloth color-fastness-to-water grading standard sample. A color-fastness-to-water testing result of the standard sample to water is ranged from grade 2 to grade 5 and includes the daily detection range of the color fastness to water in current textile and clothing fields. A method mainly includes the following preparation steps: preparation of grey fabrics, pre-treatment, dyeing, dewatering and drying, tentering, cloth inspection and coiling, sample preparation, homogeneity testing, stability testing, and packaging. The standard sample is easy to preserve and transport, and the uniformity and stability are in accordance with regulations through verification. The standard sample for cotton cloth color-fastness-to-water grading is suitable for textile color-fastness-to-water detection personnel to use in proofreading of detection results, technical training, result comparison, ability verification and the like in the inspection and detection agencies and production and circulation fields. The standard sample can solve the problems of single quality control method and laboratory ability evaluation universally existing in the present-stage detection agencies and production and circulation fields, and can ensure the accuracy and consistency of experimental results.

Description

technical field [0001] The invention belongs to the field of light industry textile inspection and quarantine standard samples, in particular to a cotton cloth color fastness grading standard sample, and also relates to a preparation method of the standard sample. Background technique [0002] Color fastness to water is one of the most basic and important test contents in the quality control of textile products. 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 water of textiles. In the past, the quality control of color fastness to water testing relied solely on laboratory comparison or proficiency testing, and the method was relatively simple. After the successful development of this standard sample, it can meet the daily quality control of the laboratory, proofreading and other purposes, and has...
