Conductive cellulose fiber and preparation method thereof

Abstract

The invention discloses a conductive cellulose fiber, which comprises 1 to 10 weight percent of polypyrrole and 80 to 89 weight percent of cellulose. The method for preparing the conductive cellulose fiber comprises the following steps of: performing cutting pretreatment on viscose subjected to spinning molding, and impregnating by using the prepared solution of pyrrole monomer and doping agents;adding an oxidant for an oxidation reaction, and adding mixed solution of sodium hydrosulfite, sodium sulfite and sodium hydroxide for a mixed reaction; and washing, desulfurizing, oiling and drying at the temperature of between 110 and 150 DEG C so as to prepare the finished conductive cellulose fiber. The prepared conductive fiber has higher conductivity under the condition of low content of conductive components, has excellent physical and mechanical properties and textile processing performance, and can be widely applied in the fields of conductive, antistatic and electromagnetic shielding materials.

Description

technical field [0001] The invention relates to the technical field of cellulose fibers, in particular to a conductive cellulose fiber and a preparation method thereof. Background technique [0002] Viscose fiber is one of the earliest chemical fibers developed and produced. Since its industrial production in the early 20th century, it has quickly become an important raw material for textiles due to its unique and excellent properties. Viscose fiber products have the excellent properties of natural fibers, good moisture absorption and air permeability, easy to dye, and the fabric is comfortable to wear, so it is more and more popular among people. Many contain viscose ingredients. Moreover, viscose fiber is made of natural cellulose, which has a wide range of sources and can be continuously regenerated. Today, when energy is increasingly scarce and resources are tight, it has significant raw material advantages. Therefore, the viscose fiber industry has developed rapidly a...

Problems solved by technology

Research in recent years also uses intrinsically conductive polymers to prepare conductive fibers, such as CN200510015491, which uses intrinsically conductive polymers such as aniline, pyrrole, and thiophene to continuously coat the surface of the matrix fiber on a coating machine. The process is simple and easy to produce. The speed is fast, but there are certain deficiencies in the uniformity of reaction and the fastness of the conductive layer, and its application field is limited to a certain extent

There is also a sputtering method, which uses glow discharge between two electrodes to attach a layer of metal film on the surface of the fiber, which requires high equipment configuration and technical conditions, and is difficult to industrialize.
