However, it has high crystallinity, high molecular chain regularity, and poor molecular structure polarity. It is very easy to generate static electricity during use and cannot be eliminated, which seriously limits its application field.
[0003] In order to increase the antistatic performance, a common method is to apply an antistatic finishing agent on the surface of fibers or fabrics, the essence of which is to adsorb hydrophilic groups on the surface of fibers or fabrics to increase the hygroscopicity of fibers or fabrics. Antistatic effect, but the hydrophilic group is only on the surface, it is easy to wash off, and the durability is not good
Another common method is to add an antistatic agent to the polymer, and then spin it to make antistatic fibers. Although this method has certain durability in antistatic effect, the existing above-mentioned methods prepare The antistatic properties of fibers are easily affected by the ambient humidity, and there is basically no antistatic property in a low-humidity environment; and due to the high molecular chain regularity and high crystallinity of polyoxymethylene fibers, it is difficult for the antistatic agent to disperse evenly in the collective Or form an effective conductive network, severely restricting its application fields and uses

Abstract
The invention discloses a permanent antistatic polyoxymethylenefiber and a preparation method thereof. The permanent antistatic polyoxymethylenefiber comprises the following raw material components in parts by mass: 100 parts of a polyoxymethylene resin, 0.1-30.0 parts of a hyperbranched polymer, 0.01-10.0 parts of a compatilizer, 0.1-20.0 parts of an antistatic agent, 0.01-5.0 parts of an antioxidant and 0.01-5.0 parts of a formaldehyde absorbent, wherein the hyperbranched polymer refers to any one of polyether type, polyester type, polyphenyl type, polyether sulfone type or polyether ketone type hyperbranched polymers. According to the antistatic polyoxymethylene fiber and preparation method thereof disclosed by the invention, the conductive channel formation and antistatic effect of the antistatic agent in the polyoxymethylene fiber can be realized, and the antistatic agent is unsuitable to transfer and separate out and has permanent antistatic capacity; the defect that the polyoxymethylene fiber easily generates static electricity is overcome, and the application field of the polyoxymethylene fiber is widened; and moreover, the preparation method disclosed by the invention is simple in process, high in operability, high in production efficiency and low in cost.
Description
technical field [0001] The invention belongs to the field of chemical product preparation, and in particular relates to a permanent antistatic polyoxymethylene fiber and a preparation method thereof. Background technique [0002] Polyoxymethylene (POM) fibers have the characteristics of high strength and high modulus, excellent alkali damage resistance and high elongation recovery. In particular, POM fiber has excellent impact durability, good scratch resistance, and high degree of fiber molecular orientation. Even if a part of the surface of POM fiber is scratched, the crack will not appear brittle and elongate, and will not be affected by the notch effect of the cut part. causing the entire fiber to break. Compared with other fibers, polyoxymethylene fibers also have excellent weather resistance, solventerosion resistance and friction resistance, and can be widely used as cement-based, rubber, plastic cords, optical fibers, optical cable reinforcement fibers and ropes, ...
