花生蛋白在碱减量腈纶表面上的接枝及接枝腈纶服用性能研究

研究了在碱减量腈纶表面用聚乙烯醇缩水甘油醚100%(PVAGE100%)交联荆接枝花生蛋白工艺,以及碱减量腈纶接枝交联花生蛋白后碱减量晴纶服用性能的变化.用红外光谱对接枝蛋白后的腈纶进行了表征.采用单因素法研究了碱减量腈纶交联接枝花生蛋白的最佳工艺参数,结果表明:碱减量腈纶用PVAGE100%接枝花生蛋白的最佳工艺条件为PVAGE100%最佳浓度31.08 g/L,最佳接枝温度120℃,最佳接枝时间40 min,花生蛋白最佳浓度31.5 g/L.碱减量接枝花生蛋白后.随着接枝率的升高,白度基本没有变化;回潮平有较大幅度增加;抗静电性能也大幅度提高;抗褶皱弹性略有下降.

Abstract：

Polyacrylonitrile was hydrolyzed by NaOH and then modified with arachin by poly vinylalcohol glycidyl ether 100%(PVAGE100%).It was characterized by FT-IR spectroscopy, and its wearability was studied.The best grafting technology was studied with signal factor method and the best technological pa-rameters were obtained: PVAGE100% concentration 31.08g/L, temperature 120℃, reaction time 40 min and arachin concentration 31.5 g/L.With the increase in the rate of grafting arachin on hydrolyzed polyac-rylonitrile, the whiteness of the polyacrylonitrile fabric showed little change, while its hygroscopic proper-ty and antistatic property increased greatly and its elasticity decreased slightly.     

涤纶表面接枝大豆蛋白工艺及接枝面科服用性能研究

涤纶织物具有突出的服用性能,但是与人体的亲和性较差,大豆蛋白具有良好的生物相容性.研究了用聚乙醇缩水甘油醚交联剂100%(PVAGE 100%)将大豆蛋白交联接枝在涤纶纤维表面上,制备涤纶接枝大豆蛋白面料.涤纶纤维表面交联接枝大豆蛋白最佳条件:接枝温度90℃.接枝时闻50 min.PVAGE100%浓度33.6 g/L(浴比:1:20).同时研究了涤纶/大豆蛋白复合面料的服用性能.结果表明:接枝率在一定范围内,复合面料吸湿性能有显著的改善,褶皱弹性,透气性、挺括性保持良好.     

丝光棉pH调控研究

研究用醋酸/醋酸钠的酸性缓冲溶液调控丝光棉pH.主要研究不同处理温度、处理时间、缓冲溶液pH对丝光棉pH的调控作用,同时研究了超声波对调控作用的影响,以及pH调控处理后的丝光棉力学性能的变化.实验表明:丝光棉的pH值可调到4～7.5.缓冲液pH越低,处理时间越长,处理温度越高,丝光棉的pH降低越快越低;超声波对丝光棉pH调控具有加速的作用.使用低pH的缓冲溶液,丝光棉的力学性能不会受到损害反而会得到加强.

Abstract：

The buffer solution of sodium acetate & acetic acid deal was used to regulate the pH of mercer-ized cotton. The regulation role of treatment temperature, treatment time and pH of the HAc/NaAc solu-tion for the mercerized cotton was studied and the effect of ultrasound on the regulation process was inves-tigated. After the pH control, the change of strength of the mercerized cotton was tested. The results in-dicated that pH in the range of 4-7.5 was suitable for mercerized cotton. With lower pH of HAc/NaAc solution,longer processing time and higher temperature, the pH of mercerized cotton dropped quicker and lower. Ultrasound showed an accelerating effect for decreasing the pH of mercerized cotton. Using a buff-er solution of low pH did not affect the mechanical properties of the mercerized cotton; instead, it im-proved them.
