Embodiment 1

[0050] A composite macromolecular coating fabric, comprising a fabric substrate layer, a 100 μm thick substrate melt layer, and a composite macromolecule coating. In this embodiment, the slurry viscosity is 5000cps, the glue coating temperature is room temperature, and the slurry coating amount is 100g / m 2 . The fabric substrate is made of PET yarn through plain weaving process. The fabric base material is pre-calendered, the calendering speed is 50m / min, and the calendering temperature is 90°C. The composite polymer coated fabric is formed by uniformly coating the composite polymer slurry on a calendered surface of the fabric substrate layer by a knife coater, and then drying the coating by heating. In the process of knife coating, due to the application of pressure and the certain hardness of the fabric substrate layer itself, the composite polymer slurry is partially embedded in the fabric substrate layer, thus forming a composite of a 100 μm thick substrate melt layer. ...

Abstract

The invention relates to a composite high-polymer coated fabric and a preparation method thereof. The composite high-polymer coated fabric comprises a base layer of the fabric and a composite high-polymer coating attached to at least one face of the base layer of the fabric; the composite high-polymer coated fabric further comprises a base melt layer which is 40-150 micrometers; the base melt layer refers to a composite structure formed by inserting a part of composite high-polymer coating into the base layer of the fabric during production; the thickness of the composite high-polymer coatingranges from 100 micrometers to 500 micrometers. By selection of the fabric base, selection of formula of the composite high-polymer coating and regulation of processing parameter, generation of the base melt layer is achieved, and thus, the product is superior to the prior art, in terms of fitting strength, hand feeling, fastness to yarn binding, and the like.

Description

technical field [0001] The invention relates to a coated fabric, in particular to a composite polymer coated fabric and its preparation method. Background technique [0002] Fabric coating generally refers to the process of uniformly coating polymer compounds on the surface of fabrics. It can not only improve the appearance and feel of fabrics, but also improve the functions of fabrics, such as making fabrics waterproof, breathable, and flame retardant. Special functions such as anti-fouling and light-shielding reflection. [0003] In the prior art, there are roughly the following types of fabric coatings: [0004] 1. PA (Polyacrylate) [0005] The advantages are: good fastness to sunlight and weather, not easy to yellow; good transparency and compatibility, which is conducive to the production of colored coating products; good washability; strong adhesion; low cost. The disadvantages are: poor elasticity, easy to wrinkle; poor surface finish; difficult to adjust the feel...
