The Manufacture Of Polysulfonamide Reinforced Anti-Static Fabric

In recent years, with the emergence of many high-tech emerging industries ,the application of many new high-temperature flame-retardant fibers were gradually expanded into almost every industry area. As China's self-developed organic high-temperature fiber, Polysulfonamide's development and application area were valued by many people.In Domestic market, high temperature fibers were almost depending on foreign imports before the advent of the Polysulfonamide,and these fibers had been monopolized by foreign technology for a long time, so the price was very expensive and the development of China-related downstream industries were restrictd.Therefore, accelerating the industrialization process of polysulfonamide and searching for new application areas, could bring significant economic effect and break out the situation of high-temperature fiber depending on imports. But as a result of the polysulfonamide's high volume resistivity and own shortcomings, there would be existenced more yarn hairiness in its spinning and using process; Polysulfonamide fabrics prone to produced static electricity in using process and would be more danger in special circumstances; Tear strength of Polysulfonamide fabrics were not meet the requirements.Therefore, this article in order to improve these shortcomings and deficiencies, carried out the following work:(1) Used a new type of spinning technology——sirofil, according to different blend ratio toproduct 24tex polysulfonamide single yarn,which spinning with different sizes and types of conductive filament (such as the organic conductive filament and stainless steel wire), and then to test the performance of single yarn.(2) Preferred a better performance of the single yarn, and then plied with 24tex polysulfonamide pure single yarn to product 48tex plied yarn. Second-order regression general rotation designing was used to obtain optimal technological parameter.(3) Selected basket weave to weave and tested the properties of the fabric,such as flame-retardant, anti-static performance, tear strength, abrasion resistance and so on.(4) Polysulfonamide blended with the organic conductive short fiber ,according to a certain blend ratio and then plied. Using a certain specifications woven into the fabric and compared with the yarns and fabrics which containing organic conductive filament.In this paper, a series of studies were carried out. The relevant results were obtained to provide the basis for developing high-temperature protective textiles and to be used as a reference for textile processing enterprises.In this article, six results were showed.First,in spinning process, too small and too thick stainless steel wires were not conducive to spinning.Because,the small stainless steel wire was easy to break out and the thick stainless steel wire had high bending rigidity,poor cohesive force,so it was hard to wrap polysulfonamide and the breaking strength of yarn was low and easy to break.Besides, sirofil spinning and conductive filament yarn worked together to improve the yarn hairiness effectively. Second, second-order regression general rotation test results showed that the single yarn twist factor and the plied yarn twist factor had an obvious effect on the performance of yarn. For this experiment, the optimization results of blend Polysulfonamide plied yarn was that the single yarn twist factor was 358 and the plied yarn twist factor was 506; the optimization results of pure Polysulfonamide plied yarn was that the single yarn twist factor was 372 and the plied yarn twist factor was 513.Third, the tear strength and tensile strength of fabric added about 4.5% of organic conductive filament were higher than pure polysulfonamide fabric,and its tear strength could reach more than 100N;While the tear strength and tensile strength of fabric which was added the stainless steel wire or organic staple fiber were slightly lower than pure polysulfonamide fabric.Fourth, after joining the conductive fibers, Polysulfonamide fabrics' density of surface charge were reduced by 50% and had good anti-static performance;At the same time,when conductive fiber content reached a certain value, continue to increase its content would not improve the fabric's anti-static performance. Fifth, adding 4.5% or 9% of organic conductive fiber had no effect on polysulfonamide fabric's flame-retardant property;Due to stainless steel wire had good flame resistance,adding stainless steel wire could increase polysulfonamide fabric's flame-retardant. In this article,all of the fabrics' flame-retardant were within the standard.Last, the Polysulfonamide fabric's wear resistance and ventilation property were better when adding conductive filament ,and the fabric of adding organic conductive filament also better than adding the stainless steel wire and organic staple fiber.
