Problems solved by technology

It can be seen from the public literature that in order to solve the problem of flame retardant and waterproof effects, the existing technical methods mainly use flame retardant glue alone to coat the surface of the fabric, or use multiple intermediate glue coating processes, but the flame retardant effect is unstable, Poor synergy with waterproof performance, reduced fabric strength, etc.

Embodiment 1

[0046] 1. Using the leading cloth, the linear density of the package after printing, washing and shaping is 650dtex, and the square meter weight is 243g / m 2 The high-strength polyamide 66 air-changing yarn plain weave fabric is placed on the fabric conveying mechanism, unwound, and wet-steamed through a high-temperature and high-humidity steamer. The hot and humid steam is supersaturated steam at a temperature of 110°C; the pressure is 1.1bar, and then Put the reverse side of the fabric flat on the surface of the high-temperature hollow smooth chrome-plated metal roller, and pass it directly under the action of tension. The tension is 110N, and the temperature of the metal roller surface is 150°C. Cooling, the cooling temperature is normal temperature;

Abstract

The invention provides a technology for a flame-retardant and water-proof coating of a fabric. The technology comprises the following steps that the fabric is subjected to wet steaming first, and theto-be-coated surface of the fabric is polished and flatted by using a high-temperature metal smooth face to obtain a fabric with a flat and smooth reverse side; under the combined action of oscillation and blade coating, the reverse side of the fabric is coated with a primer coating adhesive to obtain a primer adhesive coated fabric; under the combined action of oscillation and blade coating, theprimer adhesive coated surface of the primer adhesive coated fabric is coated with a middle coating adhesive to obtain a primer-middle adhesive coated fabric; and a hot-melt elastic polyurethane filmand the coated surface of the coated fabric are subjected to hot pressing, adhesion and combination to obtain the flame-retardant and water-proof coating.

Description

technical field [0001] The invention belongs to the technical field of textiles, and in particular relates to a flame-retardant and waterproof coating process for fabrics. Background technique [0002] Coating process is a functional fabric production and processing method. Coating can make fabrics have barrier functions, such as windproof, waterproof, flame retardant, and anti-biological and chemical agents, etc. Coated fabrics are widely used in various backpacks, tents, sleeping gear and outdoor clothing, etc., forming A large category of textile products. The basic operation method of fabric coating is to use a certain process to coat high polymer resin on one or both sides of the fabric, so that the resin and the fabric are physically combined to prepare a coated composite fabric, CN 201410345974, CN202157234U, CN201198521Y, CN103361987A, CN1990929A, NL1032490C2, CN 201610202478, CN 201710895898, etc. disclose relevant technical content. It can be seen from the publi...
