Problems solved by technology

If the flame-retardant regenerated cellulose fiber is mixed with other flame-retardant fibers, the overall flame retardancy of the mixture will be lower than that of any single flame-retardant fiber in the mixture; that is, the fiber can only be mixed with flame-retardant fibers For mixing, the flame retardancy compatibility with flame retardant fibers is low
[0009] For the above-mentioned synthetic fibers, synthetic fibers are mixed with non-flame-retardant fibers, and the dyeing characteristics of the two fibers are very different, and the dyes are also different; synthetic fibers must use a two-bath method when making flame-retardant fabrics; the two-bath method is complicated. , and the control is difficult; the efficient long-car dyeing production line cannot be used for processing and production, and it is not suitable for large-scale promotion

Abstract

The invention discloses a regenerated cellulose fiber which comprises the following components: regenerated cellulose, a component A and a component B, wherein the component A is one or more of polyvinyl chloride, polyvinylidene chloride and polyvinyl bromide; the component B is an oxide of antimony or a mixture of the oxide of antimony and an organic phosphorus burning agent; the mass ratio of dry weight of the regenerated cellulose to the component A is 100:(10-80); and the mass ratio of the component A to the component B is 100:(2-70). The invention also describes a method for producing theregenerated cellulose fiber. The regenerated cellulose with the flame retardancy prepared in the invention can be mixed with non-flame retardant cotton, viscose and other cellulose fibers, animal fibers or non-flame retardant polyester fibers, acrylic fibers, nylon and other synthetic fibers at a certain ratio, and a mixture, prepared from other fibers which are not subjected to any flame retardant treatment, has certain flame retardant properties; raw materials of the regenerated cellulose fiber are wide in sources and low in price, and the production cost can be greatly reduced.

Description

technical field [0001] The invention relates to the technical field of fire-resistant fabrics, in particular to a regenerated cellulose fiber. Background technique [0002] There are generally two ways to realize the flame retardant function of fabrics: [0003] 1. Chemical post-treatment of non-flame-retardant fabrics or fibers; artificially impregnating non-flame-retardant fabrics or fibers with chemical agents, fumigation or coating flame-retardant chemical substances on the surface of non-flame-retardant fabrics or fibers; The advantage of flame-retardant post-treatment of flame-retardant fabrics or fibers is that the price of the fabric with flame-retardant function is cheap, but the flame retardancy of the fabric will decrease with the increase of washing times; in addition, the residual chemicals on the fabric will Carcinogens such as formaldehyde are continuously released, and harmful gases that pollute the environment are emitted during the production process.
