Melt-resistant flame-proof cellulose viscose and method for making same

Abstract

The invention discloses a anti-melting flameretardant fiber and preparation method thereof. The flame-retardant is added in the dissolving procedure to using production method of viscose fiber, and then processed by mixing, filtration, ripening, debubbling, spinning, refinning, drying, and finished product to produce flameretardant fiber. When burning, the said anti-melting flameretardant fiber will not melt but only carbonize to keeping the original shape of fibre, therefore it prevent high temperature melting drip scalding the people. Furthermore the flame-retardant homogeneously disperses in viscose, and does not smolders and is easy to self extinguish after leaving fire source. The said preparation method is simple and easily operated. The flame retardant property is good, and the disperse of flame-retardant is homogeneous.

Description

technical field [0001] The invention relates to a man-made fiber, in particular to a melt-resistant flame-retardant fiber and a preparation method of the melt-resistant flame-retardant viscose fiber. Background technique [0002] In order to effectively solve the problem of fire prevention in various places, people have adopted various methods. Among them, the use of flame-retardant fibers to prevent and reduce the harm caused by fabric fires is an effective way to prevent disasters in places where fabrics are used. Method, flame retardant viscose fiber is a very common flame retardant fiber that people use at present. At present, the main method for people to prepare flame-retardant viscose fibers is the coating method, that is, after the fiber is made or during the production process (when the fiber is in a gel state), the adhesive that combines the flame retardant with other substances It is coated on the surface of the fiber in latex state. At present, there are flame r...

Problems solved by technology

At present, the main method for people to prepare flame-retardant viscose fibers is the coating method, that is, after the fiber is made or during the production process (when the fiber is in a gel state), the adhesive that combines the flame retardant with other substances It is coated on the surface of the fiber in latex state. At present, there are flame retardant adhesives combined with polyvinyl chloride latex, polyvinyl bromide latex, chlorinated paraffin or brominated aromatics, and the flame retardant Halogen-containing flame retardants are mostly used, which are non-degradable and have certain pollution after being discarded. Moreover, this kind of flame retardant is not resistant to high temperature, washing and sunlight, and the fibers in it are easy to melt and drip when exposed to fire. However, the phenomenon of scalding people occurs, and the fiber is easy to smolder after leaving the fire source, and does not self-extinguish, which brings certain difficulties to fire prevention.

There is also the use of special equipment to add flame retardants to the spinning stock solution before spinning to prepare flame-retardant viscose fibers, but the flame-retardant viscose fibers prepared by this method are not easy to operate, and their internal resistance The flame retardant is not mixed uniformly, and the uniformity of its flame retardant effect is poor, and it also increases the high cost of adding flame retardant before spinning
