摘　　要：为提高聚酰胺涂层织物的服用性能,将开纤后聚酰胺聚乙烯(PA PE)超细纤维短纤与甲醇氯化钙存在下的聚酰胺高分子溶液共混,制得超纤填充型聚酰胺涂层浆。涂层浆在涤氨纶混纺基布上经过双面刮涂、相转化、烘干等湿法涂层工艺操作,得到超纤填充型聚酰胺涂层织物。对涂层浆的黏度、相转化时间、焙烘温度等工艺条件进行设计和优化,分析比较不同制备工艺下涂层织物的微观形貌、干湿摩擦、硬挺度和掉粉情况,确定最佳涂层织物制备工艺。结果表明:涂层浆适宜的放置时间为1 h,涂层最佳厚度区间为20~24μm,当相转化时间和焙烘温度分别为5 s和80℃时,涂层织物的性能最优。To improve the wearing performance of traditional polyamide wet coating fabrics and solve various problems such as poor wear resistance and powder shedding of conventional polyamide coatings filled with inorganic powder particles such as kaolin,calcium carbonate,and wollastonite,it is necessary to find a new filler component and develop a new process flow for preparing polyamide wet coating fabrics based on this.The short fibers of polyamide polyethylene(PA PE)ultrafine fibers after fiber opening treatment were blended with methanol calcium chloride polyamide polymer solution to prepare microfiber composite polyamide coating slurry.Wet coating processes such as double-sided scraping,water bath exchange,and drying were carried out on polyester spandex blended base fabrics by using microfiber composite polyamide coating slurry to obtain a polyamide wet coating fabric filled with microfibers.Then,various testing methods were used to evaluate its wearability and other properties.The results indicate that with the increase of the amount of microfibers added,the viscosity of the coating slurry gradually increases from 246.7 mPa·s to 250.8 mPa·s.With the extension of storage time,the viscosity of the coating slurry increases from 245 mPa·s to 290 mPa·s.As the viscosity of the coating slurry increases,the coating thickness shows a significant upward trend,increasing from 20μm to 40μm.As the duration of phase transformation increases,the pore structure on the surface of the coating gradually becomes significant and dense,the stiffness of the fabric increases,and the phenomenon of powder shedding intensifies.The stiffness and coating thickness of the polyamide coated fabric filled with microfibers show an increasing trend with the increase of phase transition time,and the curve gradually becomes smooth.As the phase transition time increases,the dry and wet friction properties of the microfiber filling polyamide coated fabric show a phenomenon of first increase and then decrease.After the baking temperature is increas
