Problems solved by technology

There are many kinds of chemical fibers and they are used in a huge amount. However, in some special fields, such as chemical plants and special equipment, the fibers used often need to have high strength and acid and alkali resistance. At present, the commonly used corrosion-resistant fibers are mostly fluorine-containing fibers. Fluorine-containing fibers are expensive and the raw materials are toxic, while inorganic fibers use high-temperature drawing and consume high energy consumption

Abstract

The invention mainly relates to the technical field of processing of novel fibers and discloses novel high-strength, acid-resisting and alkali-resisting fibers. The novel high-strength, acid-resistingand alkali-resisting fibers are prepared from the following raw materials in parts by weight: 10 to 15 parts of chitosan, 60 to 75 parts of glycidyl ester type epoxy resin, 2 to 3 parts of carbon nanotube and 15 to 18 parts of nano titanium dioxide. The fibers prepared by the invention have strong acid-resisting and alkali-resisting performance, good dyeing stability and a wide application range.

Description

technical field [0001] The invention mainly relates to the technical field of novel special fiber processing, in particular to a novel high-strength acid-alkali-resistant fiber. Background technique [0002] Chemical fibers are fibers with textile properties that are made from natural polymer compounds or artificially synthesized polymer compounds through the processes of preparing spinning dope, spinning and post-treatment. There are many kinds of chemical fibers and they are used in a huge amount. However, in some special fields, such as chemical plants and special equipment, the fibers used often need to have high strength and acid and alkali resistance. At present, the commonly used corrosion-resistant fibers are mostly fluorine-containing fibers. Fluorine-containing fibers are expensive and the raw materials are toxic, while inorganic fibers are drawn at high temperatures and consume high energy consumption. Contents of the invention [0003] In order to make up for ...
