Example Embodiment

[0013] Embodiment 1, a kind of back cloth for raising clothing is characterized in that: it is composed of a base, a rubber adhesive surface and a red surface, the rubber adhesive surface is above the base, and the red surface is below the base; the base is made up of cotton cloth; The rubber adhesive surface is made by coating and drying the adhesive; the red surface is made by coating and drying water-based polyurethane paint.

[0014] The base cotton cloth adopts: cotton yarn: warp combed yarn, weft combed yarn; cotton yarn count: warp 16S, weft 21S; cotton density: warp density 105 / inch, weft density 56 / inch; cotton thickness 0.39~0.42mm, warp breaking strength 1300N, breaking elongation 9%.

[0015] The adhesive used on the surface of the rubber adhesive is made from mixing rubber A and gasoline in a mass ratio of 1:3.5;

[0016] The mixed rubber A is made by mixing the following raw materials by mass: 100 parts of Thailand No. 3 natural rubber, 1.5 parts of sulfur, 1....

Example Embodiment

[0019] Embodiment 2, a kind of back cloth for raising clothing is characterized in that: it is composed of a base, a rubber adhesive face and a red face, the rubber adhesive face is above the base, and the red face is below the base; the base is made up of cotton cloth; The rubber adhesive surface is made by coating and drying the adhesive; the red surface is made by coating and drying water-based polyurethane paint.

[0020] The base cotton cloth is the same as that of Example 1.

[0021] The adhesive used on the surface of the rubber adhesive is the same as in Example 1.

[0022] The red surface-use polyurethane paint is applied, and the paint is made of water-based polyurethane emulsion EPW-T99S and thickener 2681 mixed with color paste, and then adds 5% of water-based polyurethane with a bright red paste, wherein the water-based polyurethane emulsion and The mixing ratio of color paste is 1:2.

[0023] The performance indicators are shown in Table (1).

Example Embodiment

[0024] Embodiment 3, a kind of back cloth for raising clothing is characterized in that: it is composed of a base, a rubber adhesive surface and a red surface, the rubber adhesive surface is above the base, and the red surface is below the base; the base is made up of cotton cloth; The rubber adhesive surface is made by coating and drying the adhesive; the red surface is made by coating and drying natural rubber paint.

Abstract

The invention relates to back cloth for fluffing card clothing, which is characterized in that the back cloth is formed by combining a base part, a rubber adhesive surface and a red surface, the rubber adhesive surface is arranged on the upper surface of the base part, and the red surface is arranged on the lower surface of the base part; the base part is made of cotton cloth; the rubber adhesive surface is prepared by coating and drying an adhesive; and the red surface is prepared by coating and drying a waterborne polyurethane coating or natural rubber cement. The back cloth adhesive for the fuzzing card clothing is relatively high in adhesion stripping force which is greater than or equal to 10N/5cm, the color fastness to dry rubbing of a red surface reaches grade 4, and the dynamic friction coefficient is greater than or equal to 0.11. Skidding tends not to occur, and the product carding effect is good.

Description

technical field [0001] The invention belongs to the field of composite materials, in particular to a backing cloth for raised card clothing. Background technique [0002] Raising is to expose the fibers on the surface of the fabric to increase the thickness of the fabric, improve the hand feel and enhance the thermal insulation performance through softening. Raised card clothing is needed in the raising process. Generally speaking, there is a layer of cotton cloth on the back of the raised card clothing during use, which is called back cloth. Its main function is to prevent slipping and prevent card clothing Stretches and prevents wire needles from slipping out on the back of the base fabric. This kind of inner lining is divided into red lining and untreated white lining; the existing backing fabric has a phenomenon of degumming due to low peeling force, and low friction on the back can easily lead to slipping and affect the carding effect of the product. Contents of the ...
