Problems solved by technology

At present, Germany has a qualitative test method for saliva, which uses filter paper for staining test, and finally observes whether the filter paper is stained, so as to conclude that it is resistant to saliva or not. The disadvantage of this test method is that it cannot determine the color fastness. In the domestic test standard for color fastness to saliva, the formula of artificial saliva is unreasonable, which affects the test of color fastness of saliva in textiles; therefore, it is more reasonable to provide artificial saliva formula , and a test method that can express the level of color fastness of textiles to saliva, in order to meet the control needs of consumers and manufacturers in the domestic and foreign markets for this performance, will be of great significance

Abstract

The invention relates to the technical field of color fastness testing of textile, in particular to a testing method for color fastness to saliva of the textile. The testing method comprises the following steps of preparing artificial saliva, bonding a to-be-tested sample cut to a given size with multi-fiber accompanying fabric to form a composite sample, soaking in the artificial saliva, extruding the composite sample with a glass rod after soaking, pressing the composite sample with a counter weight, placing the composite sample in a drying oven simulating human body temperature, drying, placing the composite sample under standard atmospheric conditions with the temperature of 18-22 DEG C and the relative humidity of 61-69%, humidifying for at least four hours, and conducting an evaluation test on discoloring of the to-be-tested sample and staining of the accompanying fabric with a standard discoloring gray card and a standard staining gray card respectively. With the adoption of the testing method, the degree and the grade of the color fastness to saliva of the textile can be evaluated, deficiencies of the traditional staining test with filter paper are overcome, preparation of the artificial saliva is more reasonable, and the testing method is simple and easy to operate.

Description

[technical field] [0001] The invention relates to the technical field of textile color fastness detection, in particular to a method for testing the color fastness of textiles to saliva. [Background technique] [0002] Children's textiles, due to the particularity of their applicable objects, make consumers put forward higher requirements for their safety. Among the many requirements, children's saliva is one of the important indicators for the extraction of dyes in textiles. Dyes on textiles with poor dyeing fastness will be extracted into children's bodies through saliva, which will have a serious impact on children's personal safety. Therefore, a test method is needed to rate the colorfastness of textiles to saliva. At present, Germany has a qualitative test method for saliva, which uses filter paper for staining test, and finally observes whether the filter paper is stained, so as to conclude that it is resistant to saliva or not. The disadvantage of this test method is...
