Problems solved by technology

The existing waterproof and high-strength polyester coated cloth is generally coated with polyurethane, which can only be used under normal environmental conditions. Once it is in extremely harsh conditions, such as the cold environment or high temperature environment of the Arctic and Antarctic The physical properties of the fabric will change, and the normal physical indicators cannot be guaranteed. The properties such as UV protection, water repellency, water pressure resistance, and tear strength will be greatly weakened, and the usability will deteriorate. For example, the fabric will become stiff and feel Worse, the wearing comfort performance is reduced, the fabric will not only produce creases after folding, which cannot be restored, and more seriously, the coated surface and fabric fibers will be damaged and cracked, resulting in failure to use normally
Therefore, existing polyester coated cloth has the problem of poor weather resistance

Abstract

The invention discloses a production process of weather-resistant polyester coated cloth. The process comprises the following steps of a, dyeing the polyester cloth to obtain a product A; b, splashingand calendering the product A to obtain a product B; c, priming the product B with polyether, wherein the temperature of polyether primer is 130-170 DEG C and increased box by box, the vehicle speedis 20-30m/min, and the sizing amount is 12-15g/m2, and obtaining a product C; and d, coating surface of the product C with polyether, wherein the temperature of the polyether coated surface is 130-150DEG C and increased box by box, the vehicle speed is 30-40m/min, and the sizing amount is 8-10g/m2, and obtaining a finished product. The production process of weather-resistant polyester coated cloth has the characteristics of simple process, easy control, and good weather resistance of the prepared coated cloth.

Description

technical field [0001] The invention relates to a production process of polyester coated cloth, in particular to a production process of weather-resistant polyester coated cloth. Background technique [0002] Coated cloth mainly refers to the use of a special process to coat a layer of material with special functions on the basis of the cloth, which adds special functions to the cloth. The fabrics of some outdoor appliances, such as tent fabrics, umbrella fabrics, etc., are typical coated fabrics. In recent years, due to user needs and market competition, the requirements for coated cloth are getting higher and higher. The existing waterproof and high-strength polyester coated cloth is generally coated with polyurethane, which can only be used under normal environmental conditions. Once it is in extremely harsh conditions, such as the cold environment or high temperature environment of the Arctic and Antarctic The physical properties of the fabric will change, and the norm...
