Problems solved by technology

[0009] There was a climax in the research and development of flame-retardant fibers in China around 1990. Many companies, scientific research institutes and universities participated in it. SandofLame5060 flame retardants were used, but due to the high import price of flame retardants The quality of domestically produced flame retardants did not meet the requirements for spinning, and industrial production was not carried out in the end

Abstract

The present invention discloses a flame-retardant anti-melting viscose fiber. According to mass ratio, the viscose fiber mainly comprises the following components: 60-80 percent of cellulose, 15-26 percent of silicon series flame retardant (metered through silicon dioxide) and 3-20 percent of water. The present invention also discloses a production method for flame-retardant anti-melting viscose fiber, and the technical essential is that: in the adding step of flame retardant, the silicon series flame retardant is added into cellulose sulphonic acid ester in a yellowing step or viscose prepared after the yellowing step is over, and the addition amount is 20-45 percent of cellulose if metered through silicon dioxide. The flame-retardant anti-melting fiber produced by using the method is good in flame-retardant anti-melting effect and high in fiber strength, can lead viscose to keep good filtration performance in production process, reduces the production pause caused by that viscose clogs filter screens, and improves production efficiency. The viscose fiber can be widely used for the manufacturing of non-woven fabrics and so on.

Description

technical field [0001] The invention relates to the technical field of viscose fiber, in particular to a flame-retardant and melt-resistant viscose fiber, and also relates to a production method of the flame-retardant and melt-resistant viscose fiber. Background technique [0002] Cellulose fiber has a long history in man-made fibers and is widely used. Due to its wide source of raw materials, excellent hygroscopicity, air permeability, comfortable clothing, good dyeability and ecological relevance, it is used in the production and application of artificial fibers occupy a stable position. However, ordinary cellulose fibers are easy to catch fire and have poor flame retardancy, which cannot meet the application requirements of social development, thus limiting its application ability. [0003] With the development of society, people's safety requirements are getting higher and higher. In vehicles, public buildings, homes and offices, fire prevention issues have attracted mo...
