Embodiment 1

[0020] Embodiment one: what this embodiment provides is a kind of test method of the color fastness to soaking water that is suitable for nylon fabric, and it comprises the following steps:

[0021] a) Material preparation: cut a neat piece of fabric sample to be tested, the fabric sample to be tested should be sampled within 20cm from the edge of the fabric, and the fabric sample to be tested should be a rectangular block of 20cm×15cm; cut a piece of fabric sample to be tested Standard lining fabrics of the same specifications that have been bleached, dyed and splashed, and dyed nylon fabrics in the form of overflow are selected from TSL228 T The cloth type is used as the standard interlining fabric, and the nylon fabric dyed in the form of flat cylinder jigger is selected as 230 T Plain or 40 D Plain nylon cloth is used as the standard lining fabric; take 200ml of warm water at a temperature of 55-60°C, add 2g of Diao brand phosphorus-free natural soap powder with a moistur...

Embodiment 2

[0029] Embodiment two: what this embodiment provides is the method for testing the color fastness to soaking water suitable for polyester fabrics, which differs from the above embodiment one in that:

[0030] The standard lining fabric of cutting in step a) is peach skin 50 D (300 T ~320 T ) plain weave; the rest of the test process refers to the operation of Example 1, and will not be repeated here.

Embodiment 3

[0031] Embodiment three: what this embodiment provides is the method for testing the color fastness to soaking water suitable for polyester-cotton or nylon-cotton interwoven fabrics, which differs from the above-mentioned embodiment one in that:

[0032] In step a), two standard lining fabrics need to be cut, one of which is peach skin 50 D Plain weave and another standard lining fabric are standard pure cotton fabrics; in step b), two standard lining fabrics are respectively fixed on the upper and lower surfaces of the fabric sample to be tested; the temperature of the reagent water in step c) is adjusted to 50 ±2°C; the rest of the test process refers to the operation of Example 1, and will not be repeated here.

Abstract

The invention relates to a method for detecting color fastness of fabric products to water. The method comprises the following steps of: respectively cutting to-be-detected fabric samples with the same specification and a standard adjacent fabric subjected to bleaching, dyeing and splashing processes and preparing a liquid soap reagent with concentration of 10g / L; fixing and overlapping the standard adjacent fabric on the to-be-detected fabric samples to obtain combined samples; immersing the combined samples in the liquid soap reagent with proper temperature and standing still for detecting; taking the combined samples out, cleaning and disassembling; drying the standard adjacent fabric and the to-be-detected samples; and grading and comparing the standard adjacent fabric and the to-be-detected fabric samples with a grey standard sample card to obtain color fastness to water. The detection process is simple and feasible, the detection method is scientific and the detection results are accurate; by comparison with the grey standard sample card, the discoloration and staining grades of the to-be-detected fabric samples can be determined accurately. The unification of the detection method of color fastness of fabric products to water is beneficial to the quality detection of fabric products according to the grades of color fastness to water detected by using a unified method.

Description

technical field [0001] The invention relates to determining the influence of conventional household washing on the color of textiles, in particular to a method for testing the color fastness of textiles to soaking water. Background technique [0002] Color fastness, especially the effect of conventional household washing on the color of textiles, that is, color fastness to soaking water, is an important indicator for evaluating the quality of textiles. At present, the country does not have relevant testing standards, so that the production enterprises have no testing standards to rely on, so that they use different testing methods to measure the color fastness to soaking water. The purpose is to make it difficult to identify the quality of textiles from the existing indicators of color fastness to soaking water. Contents of the invention [0003] The invention aims to solve the deficiencies in the existing testing methods for the color fastness to soaking water of textile...
