Abstract

The invention relates to a flame retardant fiber and a preparation method thereof. The preparation method comprises the following steps: mixing cellulose or polyacrylonitrile and a flame retardant high polymer according to a ratio, dissolving at high temperature to prepare a high concentration spinning solution, filtering, cooling, pressurizing for extruding, uniformly mixing two components in the spinning solution through a shearing effect generated by pressure, and performing multiple stretching, thereby forming the blended fiber of polyacrylonitrile or cellulose with the phase domain size of less than 50nm. The flame retardant fiber, namely the blended fiber, is prepared by directly spinning, the problem of mixing uniformity is solved, and the flame retardant fiber has the excellent characteristics of good flame retardant performance, high flame retardant durability, zero halogen and phosphorus, low toxicity, comfort and the like and has significance for developing flame retardant fibers which are not toxic, less in smoke and environmentally friendly.

Description

technical field

[0001] The invention relates to a flame-retardant fiber and a preparation method thereof, in particular to a blended flame-retardant fiber obtained by direct spinning and a preparation method thereof. Background technique

[0002] Cellulose fibers and polyacrylonitrile fibers have long occupied an important position in textiles, but both fibers have the disadvantage of being easy to burn, which limits the safety of their use. In order to improve the flame retardancy of such textiles, the most commonly used methods are flame retardant finishing, adding organic or inorganic small molecule flame retardants, and copolymerization modification. Flame retardant finishing is easy to industrialize, but the durability of flame retardant is poor and affects the fabric feel; the method of adding small molecule flame retardants for blend spinning often affects spinning and fiber mechanical properties and spinning and weaving due to the large amount of addition And the us...
