Preparation method of novel anti-static anti-ultraviolet fiber

Abstract

The invention discloses a preparation method of a novel anti-static anti-ultraviolet fiber. The preparation method comprises the following steps of preparing a PA6 anti-static functional material, preparing a PET uvioresistant functional material, and performing spinning of composite fibers. The novel anti-static anti-ultraviolet fiber prepared by the invention has good anti-ultraviolet capability, anti-static capability and good mechanical property; and the weaving requirement is met, and the additional value of the fiber and a fabric is increased.

Description

technical field [0001] The invention relates to the technical field of preparation of functional spun fibers, in particular to a preparation method of antistatic and antiultraviolet fibers. Background technique [0002] The problem of insufficient antistatic and anti-ultraviolet properties has always been a persistent problem faced by chemical fiber fabrics. At present, there are some solutions such as solving the problem from the source of the fiber, which can be used to prepare polyester and nylon fibers, for example, by adding anti-static and anti-ultraviolet agents. Antistatic and anti-ultraviolet fibers can basically meet the anti-static and anti-ultraviolet requirements of fabrics. At present, they are widely used, but this type of fiber also has irreparable defects: first, antistatic fibers mostly use conductive threads, and the lowest price in the market is currently 20 10,000 / ton, and the price of anti-ultraviolet fiber is also relatively high, between 80,000 and 15...

Problems solved by technology

[0002] The problem of insufficient antistatic and anti-ultraviolet properties has always been a persistent problem faced by chemical fiber fabrics. At present, there are some solutions such as solving the problem from the source of the fiber, which can be used to prepare polyester and nylon fibers, for example, by adding anti-static and anti-ultraviolet agents. Antistatic and anti-ultraviolet fibers can basically meet the anti-static and anti-ultraviolet requirements of fabrics. At present, they are widely used, but this type of fiber also has irreparable defects: first, antistatic fibers mostly use conductive threads, and the lowest price in the market is currently 20 10,000 / ton, and the price of anti-ultraviolet fiber is also relatively high, between 80,000 and 150,000 / ton, which is relatively expensive for traditional textiles; second, the mechanical properties of fibers are poor, and there are more and more knitted fabrics. Especially warp knitted fabrics are more and more widely used, but the mechanical properties of the fibers are also high, and the fibers added with antistatic and anti-ultraviolet agents affect the mechanical properties of the fibers due to the influence of the anti-static and anti-ultraviolet agents, which limits their mechanical properties. Scope of application; Third, the temperature resistance is poor, and the heat resistance of fibers added with antistatic and anti-ultraviolet agents is lower than that of ordinary fibers, which also affects its scope of use

[0003] At present, the preparation technology of antistatic and anti-ultraviolet fibers is still in the hands of developed countries such as the United States and Japan, which is not conducive to the development of Chinese products.

At present, many fabrics on the market are finished with antistatic and anti-ultraviolet agents to realize the anti-static and anti-ultraviolet function of the fabric. Manufacturers use it, but although this method is cheap and effective, it also has inevitable defects: 1) Additional pollution. At present, antistatic and anti-ultraviolet agents are generally used for post-finishing, which increases the pollution degree of wastewater and also increases the treatment of wastewater. Difficulty; 2) Persistence is not enough. The antistatic and anti-ultraviolet finishing methods currently used have poor washability, and generally seldom have the washability that can meet the standard requirements, which is not conducive to the export of textiles and reduces the competitive advantage of textiles.
