Abstract

The invention relates to a preparation method of the easy dyeing flame-retardant non-woven fabric and belongs to the technical field of a building decoration material. Raw materials such as flame-retardant fibers are first processed through scraping, then scraps and the dye are mixed and stirred and then heated, through combination of the scraps, the dye and the raw materials are made to be more evenly mixed, products have good average performance, the products are evenly dyed and are not easy to fade, fire resistance is greatly improved, after extrusion and sizing of the products under the high temperature, the longitudinal and transverse tensile strength of the non-woven fabric is enhanced, and the non-woven fabric can be widely used in fire-fighting clothing, fire-fighting products, wall coverings and various veneer materials.

Description

technical field [0001] The invention belongs to the technical field of building decoration materials, and relates to a processing technology of non-woven fabrics, in particular to a preparation method of easily dyeable flame-retardant non-woven fabrics. Background technique [0002] Non-woven fabrics are made of textile raw materials, such as polyester, acrylic, nylon, polyvinyl chloride, cotton, hemp and other natural plant fibers, which are formed through non-woven fabrics, that is, products produced through non-woven fabric production processes are called non-woven fabrics. Because of its pure color, visual comfort, soft touch, sound-absorbing and breathable, elegant and noble, non-woven products are the first choice for high-end home decoration. Compared with ordinary wallpaper, they are easier to post, more waterproof, not easy to seam, no warping, and the seams are intact. , natural quality, fragrant smell, however, with the improvement of people's living standards, th...
