The problem of insufficient antistatic and uvioresistant performance is a persistent problem faced by chemical fiber fabrics, some solutions are provided at present, for example, the solutions are solved from the original source of fibers, terylene and nylon fibers can be prepared, for example, antistatic and uvioresistant fibers are prepared by adding an antistatic and uvioresistant agent, the requirements of the fabrics on antistatic and uvioresistant can be basically met, the antistatic and uvioresistant fibers are widely applied at present, but the fibers also have the irreparable defect: firstly, the antistatic fiber is mostly made of conductive filaments, the lowest price of the antistatic fiber in the current market is about 20 ten thousand per ton, the price of the ultraviolet resistant fiber is higher and is between 8 and 15 ten thousand per ton, and the price is higher than the cost of the traditional textile; secondly, the mechanical property of the fiber is poor, the knitted fabrics are more and more at present, particularly the warp-knitted fabrics are more and more widely applied, but the mechanical property of the fiber is higher, and the fiber added with the antistatic and uvioresistant agent influences the mechanical property of the fiber due to the influence of the antistatic and uvioresistant agent, so that the application range of the fiber is limited; thirdly, the heat resistance is poor, and the heat resistance of the fiber added with the antistatic and uvioresistant agent is lower than that of the common fiber, which also influences the application range of the fiber. The prior preparation technology of the antistatic uvioresistant fiber is also mastered in developed countries such as America and the like, and is also unfavorable for the development of Chinese products. At present, more fabrics on the market adopt the antistatic and ultraviolet resistant agent after-treatment to realize the antistatic and ultraviolet resistant functions of the fabrics, and compared with the mode of using conductive fibers, the mode has lower cost and obvious effect, thereby being used by most fabric manufacturers, but the mode is low in cost and effective, and has inevitable defects: 1) additional pollution, namely, the adoption of an antistatic and uvioresistant agent for after-treatment generally increases the pollution degree of the wastewater and increases the treatment difficulty of the wastewater at present; 2) the durability is not enough, the washing fastness of the currently adopted antistatic ultraviolet resistance after-finishing mode is poor, generally, the washing fastness which can meet the standard requirement is rare, the export of textiles is not facilitated, the competitive advantage of the textiles is reduced, and the dispute in trade is increased.
The invention provides a third mode, namely a novel antistatic ultraviolet resistance fiber is prepared by adopting two component fibers with a parallel structure, the fiber diameter can be ultrafine fiber, the fiber can be made into light color, the permanent antistatic ultraviolet resistance function is realized, the mechanical property can reach the standard of common fiber, the requirements of various weaving are completely met, the cost is equivalent to that of the antistatic ultraviolet resistance after-finishing, and the pollution and the raw material cost are reduced. The ultraviolet resistance function is generally required in summer, the ultraviolet resistance function is required for light and thin clothes fabric, the PA system raw material is adopted to just endow the fabric with cool feeling, and the moisture absorption property is good, the wearing comfort is strong, and the PET polyester has the quick-drying effect, so the combination of the PA system raw material and the PET polyester can achieve the moisture absorption and quick-drying function, and the fabric is particularly suitable for development of clothes fabric in spring and summer.
