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 discloses a preparation method for a novel corrosion-resistant high-strength fiber, mainly belonging to the technical field of processing of novel fibers. The novel corrosion-resistant high-strength fiber is prepared from the following raw materials by weight: 10 to 15 parts of chitosan, 60 to 75 parts of glycidyl ester type epoxy resin, 2 to 3 parts of carbon nanotubes and 15 to 18parts of nanometer titanium dioxide. The fiber prepared in the invention has strong acid and alkali resistance, 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 preparation method of a corrosion-resistant high-strength novel 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...
