Flame-retardant nonwoven

Abstract

The invention discloses a flame-retardant non-woven fabric. The non-woven fabric contains 40-60 parts by weight of polyester fiber, 10-30 parts of seaweed fiber, and 10-50 parts of flame-retardant viscose fiber. ; Polyester fiber, seaweed fiber and flame retardant viscose fiber are evenly mixed and then enter the opener, polyester fiber, seaweed fiber and flame retardant viscose fiber are output from the opener and enter the carding machine, and the raw materials are sent out from the carding machine After entering the net laying machine, pre-stabbing machine, barbed machine, and main piercing machine, it is hot-rolled at a high temperature. The temperature of the hot-rolling is 225 ° C ~ 230 ° C. After hot-rolling, the flame-retardant non-woven fabric enters the crimping machine and the calender machine. Flame retardant non-woven fabric. The polyester fiber, seaweed fiber and flame-retardant viscose fiber of the present invention are blended in a suitable ratio, so that the flame-retardant performance and comfort performance are both achieved, so as to achieve the best use effect.

Description

technical field [0001] The invention relates to the technical field of textile materials, in particular to a flame-retardant non-woven fabric. Background technique [0002] Since the raw materials of non-woven fabrics, such as polypropylene, are hydrocarbon materials, which are easy to burn, the current process of making flame-retardant non-woven fabrics is usually to soak non-woven fabrics in a flame retardant solution for a period of time, then take them out and dry them. The process is long and it is easy to cause waste of flame retardant solution. At present, in the domestic market, there are temperature-regulating fibers made of sliced ​​fibers containing a small amount of temperature-regulating elements through spinning, and then woven into cloth or spun into temperature-regulating yarns. Although it has less temperature adjustment function, it does not have flame retardant function. In the international market, there are temperature-regulating non-woven fabrics coate...

Although it has less temperature adjustment function, it does not have flame retardant function

In the international market, there are temperature-regulated non-woven fabrics coated on non-woven fabrics. The coating is irregular square, but it does not have flame retardant function.
