假发用蛋白/纤维素共混丝的制备及性能研究

Preparation and properties of protein/cellulose blended filament for wig

使用离子液体溶解羊毛和纤维素纤维制备共混丝，为生产制备假发提供环保原料。首先制备离子液体[Bmim]Br，然后用其溶解羊毛和纤维素纤维，探究不同的溶解温度、时间对纤维素纤维和羊毛溶解度的影响。探讨r羊毛／纤维素纤维共混比、凝固浴种类、凝固浴温度等因素对纺丝效果的影响，最后对羊毛／纤维素纤维共混丝进行了阻燃处理。离子液体[Bmim]Br溶解羊毛的最佳工艺为：温度120℃，溶解时间10h，搅拌器转速350r／min。溶解纤维素纤维的最佳工艺为：温度100℃，溶解时间6h，搅拌器转速350r／min。共混丝纺丝最佳工艺为：6％羊毛溶液和6％纤维素溶液共混比为3：7，搅拌器转速为350r／min，混合温度60℃，凝固浴为蒸馏水，凝固浴温度为25℃。利用阻燃剂SFR一130对共混丝进行阻燃处理，共混丝的阻燃性能得到明显改善。

The blended filament is prepared by dissolving wool and cellulose with ionic liquids, and it is used as green and environment- friendly raw material for the production and preparation of wigs. Firstly, synthesis of ionic liquid [Bmim] Br is carried out, which is then used to dissolve wool and cellulose. The effects of the dissolution temperature and time on the solubility of cellulose and wool are explored, and the influencing factors of wool/cellulose blending ratio, coagulation bath type, coagulation bath temperature on the spinning are discussed, finally the blended yarn is treated with flame retardant finish in order to improve the safety in use. The results show that the optimum process of ionic liquid [Bmim] Br to dissolve wool is： dissolving in ionic liquid [Bmim] Br at 120℃ for 10 h, and stirring speed at 300 r/min. The optimum dissolution of cellulose is carried out at 100℃ for 6 h with 350 r/min stirrer speed. The optimum spinning for blend filament is ratio of wool and cellulose 3 ： 7, stirring at 350 r/min, mixing at 60℃, and coagulation in distilled water bath of 25℃. Finally, tlame retardant finish is carried out on blend filament weith SFR-130, and it is found that flame retardant property is obviously improved.
