Preparation method of in-situ polymeric composite conductive/antistatic fiber

Abstract

The invention provides a preparation method of an in-situ polymeric composite conductive / antistatic fiber. The preparation method comprises the following steps of carrying out the surface modification of nano conductive powder, preparing an antistatic master batch, and drying the antistatic master batch for 2 to 8 hours at a temperature of 100 to 180 DEG C, uniformly mixing the antistatic master batch with a basic resin slice, and afterwards, carrying out melt spinning, so as to obtain the in-situ polymeric composite conductive / antistatic fiber, wherein a spinning speed is 600m / min to 3,000m / min; the initial pressure of a spinning component is 8MPa to 16MPa. A brand-new antistatic mechanism is adopted by the preparation method to prepare a novel antistatic fiber; the in-situ polymeric composite conductive / antistatic fiber has a permanent antistatic function; the mechanical performance can reach the standard of a common fiber; the requirements of various kinds of weaving are completely met; the cost is equivalent to that of antistatic finishing, which is only quarter of that of the using of a white conductive fiber; the pollution is reduced; by using the preparation method, the export of a textile can be expanded; the value added of the textile is promoted.

Description

technical field [0001] The invention belongs to the technical field of functional textile materials, and in particular relates to a preparation method of in-situ polymerized composite conductive / antistatic fibers. Background technique [0002] The antistatic problem has always been a persistent problem faced by chemical fiber fabrics. At present, there are some solutions, such as solving from the source of the fiber, which can prepare conductive fibers, such as using high additives and composite spinning technology to prepare conductive fibers. The conductive fibers used The powder is ATO, AZO, ITO, or conductive carbon black, etc. The resistance of the fiber can reach 106 ohms or even lower, which can fully meet the antistatic requirements of fabrics, and is currently widely used in some security fields. But such fibers also have irreparable defects: [0003] First, the cost is too high. The current lowest price of white conductive fiber in the market is around 250,000 / ton...

AI Technical Summary

Problems solved by technology

[0003] First, the cost is too high. The current lowest price of white conductive fiber in the market is around 250,000 / ton, which is unacceptable for traditional textiles;

[0004] Second, the mechanical properties of fibers are poor. At present, there are more and more knitted fabrics, especially warp knitted fabrics, which are more and more widely used, but the mechanical properties of the fibers are also high. Widely used in knitting field;

[0005] Third, the diameter of the fiber is too thick. The single fiber fineness of the conductive fiber currently on the market is about 6-10D, which will produce a strong itching sensation and affect the feel and style of the fabric;

[0006] Fourth, the color difference of fibers. Conductive fibers are generally colored. At present, black, gray or light-colored conductive fibers are mainly used in the market. The difference in these colors will make the fabric form stripes or hidden patterns, which will affect the visual effect of the fabric.

However, although this method is cheap and effective, it also has inevitable defects:

[0008] (1) Additional pollution. At present, antistatic agents are generally used for finishing, which increases the degree of pollution of wastewater and increases the difficulty of wastewater treatment;

[0009] (2) The durability is not enough. The antistatic finishing method currently used has poor washability. Generally, there is little washability that can meet the standard requirements, which is not conducive to the export of textiles, reduces the competitive advantage of textiles, and increases trade. disputes in
