Chemical fabric cover plate type flame-retardant layer coating process

Abstract

The invention discloses a chemical fabric cover plate type flame-retardant layer coating process, and belongs to the technical field of chemical fabrics. According to the chemical fabric cover sheet type flame-retardant layer coating process provided by the invention, after flame-retardant glue is sprayed on the surface of chemical fabric, by utilizing the attraction effect of a magnetic field on permeation-assisting cover plates, the permeation-assisting cover plates are forced to cover and extrude the flame-retardant glue on the surface of the chemical fabric, the internal deformation action is triggered, the permeation-assisting cover plates are continuously attracted by the magnetic field after the whole is broken up into parts, and more detailed multi-point extrusion is carried out on the flame-retardant glue, so that the chemical fabric is forced to have a good stretching effect locally, pores of the chemical fabric are increased, permeation of the flame-retardant glue into the chemical fabric is accelerated under the extrusion actions of the permeation-assisting cover sheets, and compared with the self-permeation action of the flame-retardant glue, a more excellent coating effect can be achieved through obvious external force intervention in the chemical fabric cover plate type flame-retardant layer coating process; and the permeation effect is locally concentrated and then integrally covered in a multi-covering mode, so that the coating quality of the flame-retardant glue is remarkably improved.

Description

technical field [0001] The invention relates to the technical field of chemical fiber cloth, and more specifically, relates to a coating process for a cover-type flame-retardant layer of chemical fiber cloth. Background technique [0002] Chemical fiber cloth is the abbreviation of chemical fiber fabric. It is a kind of fiber textile made of polymer compound. It is usually divided into two categories: man-made fiber and synthetic fiber. Chemical fiber fabric is a new type of clothing material developed in modern times, with many types. Here mainly refers to the pure spinning, blending or interlacing fabrics processed from chemical fibers, that is to say, fabrics woven from purified fibers, excluding blending and interlacing fabrics with natural fibers. It is determined by the characteristics of the chemical fiber itself. [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 us...

Problems solved by technology

[0004] However, the existing coating process mainly relies on the penetration of the flame-retardant adhesive itself, and it is difficult to effectively penetrate into the chemical fiber cloth. As a result, the flame-retardant adhesive simply adheres to the cloth surface and is not tightly combined with the cloth surface, which is prone to degumming of the cloth surface. Phenomenon
