Problems solved by technology

[0004] At present, the instrument used to test the solid stain resistance of textiles is mainly the Martindale instrument applied to coated fabrics. The method is to rub the standard stained cloth with the surface of the sample, and after rubbing, use the textile color fastness gray However, this method requires the use of standard stained cloths, which cannot be widely used due to the difficulty of obtaining uniform standard stained cloths

Embodiment

[0032] Embodiment: test fabric is the white down jacket fabric of antifouling finishing

[0033] Take 3 samples with a size of 70mm×100mm and place them on the elastic gaskets of the lower clamping piece respectively, and press the upper clamping piece down on the sample, so that the rectangular hole and the elastic gasket and the sample bite together. Roll the sample fixture into a cylindrical shape along its length and put it into the cylinder, then fasten a cylinder cover with the cylinder body, put the cylinder into the inversion box, close the box cover, and start the inversion box, stop after turning 200r . Take out the sample, blow off the dirt attached to the surface of the sample with a hair dryer, use the original sample as a comparison sample, and use the gray scale for color fastness staining of textiles to evaluate the staining grade of each sample. The staining grades of the three samples are respectively grade 3, grade 3 and grade 3.5, so the grade of antifouli...

Abstract

The invention relates to a testing apparatus and a testing method for textile resistance of solid state dirt contamination. The apparatus is characterized in that: the textile is positioned in a sample fixture; an upper fixture piece and a lower fixture piece are used for holding the textile through the interlocking of a rectangular hole and an elastic gasket; the sample fixture is positioned in a cylinder, and solid state dirt is added into the cylinder; and the cylinder is rotated in a cubic tumbling box. Through the impacting of the cylinder and the cubic tumbling box, a solid state dirt contamination process of the textile during application can be simulated and accelerated.

Description

Technical field: [0001] The invention relates to the field of textile testing, in particular to a testing device and a testing method for the solid dirt resistance of textiles, which are suitable for the development, production and testing of antifouling textiles. Background technique: [0002] In recent years, antifouling textiles have developed rapidly, such as used to make work clothes for workers who are frequently exposed to mineral oil and animal and vegetable oils, and are also used in ordinary garments, jackets, casual clothes, and sleeping bags. Antifouling textiles can be divided into anti-liquid dirt and anti-solid dirt according to different pollutants. Liquid dirt refers to oil-soluble and water-soluble dirt liquids such as edible oil, soy sauce, engine oil, and coffee. Solid dirt generally refers to solid forms such as atmospheric dust, rust, pigments, and small black particles formed by the combination of automobile exhaust and air dust. of dirt. The contami...
