Embodiment 1

[0026] 1) Main test instruments (device), materials and reagents: color fastness tester to perspiration (according to ISO 105-E01), multi-fiber lining fabric (according to ISO 105-F10), oven (temperature maintained at 37°C±2°C) ,

[0027] ISO gray sample card

[0028] 2) Urine solution configuration: take urea 35.0g, sodium chloride 16.5g, calcium phosphate 1.2g respectively, measure phosphoric acid 3.0ml of 85% mass concentration, 2.0ml of sulfuric acid of 98% mass concentration, 3.0ml of 37% hydrochloric acid ml, 6.5ml of ammonia water with 28% mass concentration, and distilled water or tertiary water to prepare 1 liter of solution.

[0029] 3) Sample preparation: Take a 40mm×100mm sample from the sample to be tested, contact the front with a 40mm×100mm multi-fiber lining fabric, and sew along one short side to form a combined sample.

[0030] 4) Implementation steps:

[0031] 1). Take an appropriate amount of the prepared urine solution, and place the combined sample in ...

Abstract

The invention relates to a test method of urine stain color fastness, which comprises the following steps: preparing a urine reagent and a test sample; soaking the test sample in the urine reagent; removing the redundant urine reagent on the test sample, and pressing the test sample to be flat; keeping the test sample still in a flat state at a suitable temperature for appropriate time; taking the test sample out, unfolding and drying in air with the temperature no higher than 60 DEG C; and evaluating the discoloration of the test sample and the staining of a multiple fiber accompanying fabric attached on the test sample by utilizing an ISO gray scale. The test method provided by the invention is simple and feasible, and is applied to textiles comprising different components and textures and the production thereof as well as various non-woven fabrics and the products thereof. The invention makes up the blank of the technology in the filed at home and abroad, restricts the production quality control and quality control level, and influences the quality supervision work of relative quality departments.

Description

technical field [0001] The invention relates to a method for testing the color fastness of fabrics and their products, which is suitable for testing the color fastness of textiles and their products with different components and different structures, and various non-woven fabrics and their products. Background technique [0002] Ecological, environmental protection and safety textiles are increasingly concerned by people. Europe and China have successively issued relevant regulations and standards oko-Tex 100 and GB18401, including color fastness to rubbing, color fastness to perspiration and color fastness to saliva, but did not consider The indicator of color fastness to urine stains. Underwear and children's clothing, especially infant clothing, are often contaminated with urine when they are worn. After the urine comes into contact with textiles / clothing, under certain temperature and pressure conditions, it will chemically react with the dye, and the extracted dye will ...
