Problems solved by technology

Carbon black is the best antistatic agent additive. The disadvantage is that the antistatic fiber is too dark in color and can only be used to dye and weave dark fabrics. The conductivity of other ordinary white metal oxides is relatively low, so it is used in When preparing fibers with excellent antistatic properties, it is necessary to add a large amount of white metal oxides, which often reduces the mechanical properties of the fibers. Only the composite spinning method can be used to prepare antistatic fibers with better mechanical properties, and due to metal oxidation The compatibility between the substance and

example 1

[0016] Example 1. Mix the whiskers and dispersant weighed in a certain proportion evenly, gradually add deionized water to make it completely wet, and after diluting to a certain concentration, stir for 1 hour with a high-speed shear emulsifier to form a well-dispersed , Whisker slurry with good fluidity. Add whiskers to wet acrylic fiber spinning, that is, add dispersed whisker slurry in the coagulation bath (whisker concentration in the coagulation bath reaches 5%), whiskers diffuse into the primary fibers in the bath, other spinning The process is unchanged, and the antistatic acrylic fiber is obtained, and the sample number is 1.

example 2

[0017] Example 2. Mix the whiskers and dispersant weighed in a certain proportion evenly, gradually add deionized water to make it completely wet, and after diluting to a certain concentration, stir for 1 hour with a high-speed shear emulsifier to form a well-dispersed , Whisker slurry with good fluidity. Add whiskers to wet acrylic fiber spinning, that is, add dispersed whisker slurry in the coagulation bath (the concentration of whiskers in the coagulation bath reaches 3%), and the whiskers diffuse into the primary fibers in the bath, and other spinning The process is unchanged, and the antistatic acrylic fiber is obtained, and the sample number is 2.

example 3

[0018] Example 3. Mix the whiskers and dispersant weighed in a certain proportion evenly, gradually add deionized water to make it completely wet, and after diluting to a certain concentration (5%), stir for 1 hour with a high-speed shear emulsifier , forming whisker slurry with good dispersion and good fluidity. Adding whiskers to wet acrylic fiber spinning, that is, adding dispersed whisker slurry into the preheating bath, the whiskers diffuse into the primary fibers in the bath, and other spinning processes remain unchanged, and antistatic acrylic fibers are obtained. Sample The number is 3.

Abstract

The present invention relates to a preparation method of spinning chemical fibre modified and treated by whisker material, and is characterized by that said preparation method includes the following steps: mixing whisker material and dispersing agent uniformly, adding deionized water, diluting and stirring by using high-speed shearing emulsifying machine to form whisker slurry material, in the wet spinning process of the chemical fibre adding the whisker slurry material so as to obtain the modified chemical fibres of acrylic fibre, viscose fibre and vinylon, etc. with the function of resisting static electricity, resisting bacteria and resisting UV ray, so that it has the extensive application.

Description

[technical field] [0001] The invention relates to the technical field of polymer synthetic fibers, in particular to a preparation method of whisker material modified spinning chemical fibers. [technical background] [0002] During the production and use of traditional fibers and their products, static electricity is generated due to factors such as friction, drafting, compression, electric field induction, and hot air drying. If these static charges cannot be dissipated quickly, they will accumulate on materials and textile machinery, and when they reach a certain level, they will cause various hazards. With the increasing production and application of chemical fibers in textiles, and the formation and processing of chemical fibers As the speed increases, the charging phenomenon of fibers and their products and the resulting electrostatic hazards are also becoming more and more serious. Static electricity not only leads to difficulties in textile processing, such as difficu...
