共混纤维虽然共混方式和用途千差万别,但是大多是希望通过共混,综合各组分聚合物的优良性能,以得到优于单组分纤维性能的新型纤维。由于共混、熔融纺丝在原有的设备工艺基础上稍加调整即可获得各种高附加值的功能纤维,节约设备投资与技术改造的资金,因此被工业界广泛采用。例如将液晶高分子与热塑性树脂共混、熔融纺丝,以提高纤维的力学性能;向聚丙烯纤维中共混加入少量的聚苯乙烯、无机粉体等,可有效提高聚丙烯纤维的染色性化粪池模具 精密铸造 钢纤维 盐水注射机 风电基础模具 nsk轴承经销商 nsk轴承总代理 保定空调移机;向化学纤维中共混加入纳米氧化钛、纳米氧化银可分别获得具有抗紫外线、抗菌纤维;例如热塑性树脂/热塑性树脂进行共混、熔融纺丝,再通过合适的溶剂除去海相可制备超细纤维,甚至还可制备纳米纤维,工业上采用类似方法生产高级人造鹿皮等。 Although the blending methods and applications of blended fibers vary greatly, most of them hope to obtain new fibers superior to single component fibers by blending and synthesizing the excellent properties of each component polymer. Blending and melt spinning can obtain various kinds of high value-added functional fibers with slight adjustment on the basis of the original equipment and process, thus saving equipment investment and technical transformation funds, so it is widely used in industry. For example, blending liquid crystal polymer with thermoplastic resin and melt spinning to improve the mechanical properties of the fiber; adding a small amount of polystyrene and inorganic powder into the polypropylene fiber can effectively improve the dyeing property of the polypropylene fiber; adding nano titanium oxide and nano silver oxide into the chemical fiber can obtain anti ultraviolet and antibacterial fiber respectively; for example, thermoplastic fiber can be obtained Superfine fibers and even nanofibers can be prepared by blending resin / thermoplastic resin, melt spinning and then removing marine phase by appropriate solvent. In industry, advanced artificial deer skin is produced by similar method |
