Example Embodiment

[0020] The present invention will be described in detail below in conjunction with the drawings and embodiments.

[0021] Such as figure 1 As shown, the present invention includes a base fabric 1 of polyester air-textured yarn (air-textured yarn) fabric. Both the upper and lower surfaces of the base fabric 1 are coated with a thin layer of low-modulus polyurethane adhesive layer 2 with a relatively low degree of polymerization. A thin layer of high modulus polyurethane glue layer 3 is coated on the surface of the upper and lower low modulus polyurethane glue layers 2.

[0022] In the above embodiment, the upper and lower surfaces of the base fabric 1 are equally divided into two coatings. The low modulus polyurethane adhesive layer 2 applied for the first time is the primer, and the thickness of the adhesive layer varies depending on the structure of the base fabric. , The dry weight gain of the low modulus polyurethane adhesive used in the low modulus polyurethane adhesive layer ...

Abstract

The invention relates to a wear-resistant and easily-stain-removing luggage fabric and a processing method thereof. The wear-resistant and easily-stain-removing luggage fabric is characterized by comprising base cloth made of polyester air texturing yarns or an interlaced yarn fabric, wherein the upper surface and the lower surface of the base cloth are both coated with a thin low-polymerization-degree low-modulus polyurethane adhesive layer; the surface layers of the low-modulus polyurethane adhesive layer are respectively coated with a thin-layer high-modulus polyurethane layer; 0.5%-10% of cellulose prepolymer components for extinction, resisting blocking and aging are added in high-modulus polyurethane adhesive in a mixing manner; the upper surface and the lower surface of the base cloth are coated twice; the low-modulus polyurethane adhesive layer is coated with primer for the first time so as to be used as a blocking layer; the high-modulus polyurethane adhesive layer is coated with surface adhesive for the second time so as to be used for enhancing the waterproofness and the wear resistance. The wear-resistant and easily-stain-removing luggage fabric and the processing method thereof, which are provided by the invention, are widely adopted for processing products of various luggage, tool bags, protective covers, tents and the like.

Description

technical field [0001] The invention relates to a luggage fabric, in particular to a wear-resistant and easy-to-decontaminate luggage fabric and a processing method thereof. Background technique [0002] With the continuous improvement of people's living standards, more and more people go out to perform official duties and travel, and the requirements for bags are also getting higher and higher, especially in some special occasions, the requirements for the aesthetics and wear resistance of bags are more stringent. In view of the requirement on the material strength, the base cloth of the existing luggage fabric usually adopts polyester or nylon fabric, and a layer of resin coating is coated on the outer surface or the inner surface of the base cloth. In order to adapt to the use requirements of the final product, these coating materials are usually relatively thick to obtain a crisp appearance and rich feel, but in cold environments, the fabrics of luggage and bags feel sti...
