Coating process for flame retardant glue for chemical fiber cloth

Abstract

The invention relates to a coating process for flame retardant glue for chemical fiber cloth. The process comprises the following steps of base cloth manufacturing, coating preparation, a preheating process, a tentering and glue pre-spraying process, a tentering and gluing process, a drying process, surface treatment and a winding process, wherein primary tentering is performed on the cloth coverby a needle clamp on a conveying belt, glue pre-spraying is performed on positions, which occupy 10% to 15% of the cloth width, at two ends of the chemical fiber cloth by a glue pre-spraying device onthe upper part of the conveying belt, and secondary tentering and gluing are performed on the cloth cover of the chemical fiber cloth by a tentering and gluing device; fiber gaps of the chemical fiber cloth are uniformly increased through primary tentering and secondary tentering fixation, the flame retardant glue at each position of the cloth cover is uniform in penetration, the gluing effect ofthe flame retardant glue is better, the chemical fiber cloth after gluing is subjected to glue scraping by a scraping plate of a uniform scraping mechanism and is wound by a winding component finally. The coating process has the advantages of simple and reasonable structure and good gluing effect.

Description

technical field [0001] The invention relates to the technical field of smearing flame-retardant materials for textiles, in particular to a flame-retardant glue coating process for chemical fiber cloth. Background technique [0002] Chemical fiber fabric is a new type of clothing material developed in modern times, with many types. Here it mainly refers to pure spinning, blending or interlacing fabrics processed from chemical fibers, that is to say fabrics woven from purified fibers. [0003] As we all know, chemical fiber cloth has poor heat resistance and is easy to burn, which often causes serious loss of life and property during use. With the continuous development of science and technology, people have higher and higher requirements for the functional application of textiles, one of flame retardancy and water resistance, including textiles used in special environments. Therefore, it is very important to carry out high-quality and efficient flame-retardant material coat...

[0004] In the Chinese patent with the patent number CN 107497637B, a high-efficiency textile coating process is disclosed, including a preheating process, a coating process, a drying process, and an output coiling process, and by changing the traditional coating method, the front and rear The first unwinding device and the second unwinding device are set, and the first textile and the second textile are conveyed up and down in the preheating process, the coating process, and the drying process, so that the first textile and the second The textile coating process is carried out synchronously, the first textile and the second textile overlap each other, and the glue dripped on the first textile is reused on the second textile to improve the utilization rate of raw materials, but the glue coating During the process, the cloth surface is not stretched, the flame retardant glue is simply attached to the cloth surface, and the combination with the cloth surface is not tight enough, and the phenomenon of degumming of the cloth surface is easy to occur, and the surface of the cloth surface after gluing is not carried out. After the glue is applied, the flatness of the cloth surface is poor, and the winding process is simple, which may easily cause wrinkles, skewing and other phenomena when the fabric is rolled, which will affect the product quality.
