摘要
超细纤维合成革基布(USFSLB)吸湿透湿性差,研究了通过对USFSLB的聚酰胺纤维羟基化来提高其吸湿透湿性能。以纯聚酰胺纤维(nylon)为研究模型,用甲醛对nylon进行处理,得到Nylon-OH。并根据Nylon-OH的最优条件进行了USFSLB-OH的应用研究,结果表明其最佳反应条件为:温度60℃,甲醛用量100m L,反应时间15h,磷酸与甲醛的体积比为3∶100。经水接触角测定,扫描电子显微镜(SEM)、原子力显微镜(AFM)和X光电子能谱(XPS)表征,证实nylon表面被成功修饰上羟基,与未修饰的USFSLB相比较,USFSLB-OH的吸湿透湿性能得到提升。
The moisture absorbption and permeability improvement of moisture absorption and permeability of superfine fiber synthetic leather base (USFSLB) is poor. of USFSLB was studied with hydroxylation of polyamide fibers (nylon). Using pure nylon as the study model, nylon was modified with hydroxyl (Nylon-OH) by formaldehyde. The application of USFSLB-OH was carried out according to the optimal conditions of Nylon-OH. Results show that the optimal conditions of prepared USFSLB-OH are as follows, the reaction temperature is 60%, dosage of formaldehyde is 100mL, reaction time is 15h, the volume ratio of phosphoric acid and formaldehyde is 3 : 100. The results of water contact angles measurement, scanning electron microscope (SEM), atomic force microscope (AFM) and X-ray photoelectron spectroscopy (XPS) characterization prove that the hydroxyl is successfully introduced on the surface of nylon. Comparing with untreated USFSLB, the moisture absorption and permeability of USFSLB-OH is improved.
