Influences of cross blowing, spinning speed, PA6 and PET component ratio, drawing condition etc. on the mechanical properties, heat shrinkage,orientation and crystallization of the fiber were investigated. Also the rules among these influencing parameters were obtained. The splitting property of the fiber and its influence on the textile processing are discussed, which offers a base for the production of PA6/PET bicomponent fiber using splitting technology.展开更多
用硅烷偶联剂KH550和二苯甲烷二异氰酸酯(MDI)分别对磨细玻璃纤维(MGF)进行表面改性(即KMGF,M-MGF),采用熔融法制备PA6/MGF复合材料。实验结果表明:PA6/M-MGF复合材料中M-MGF质量分数为20%时,拉伸强度从65.82 MPa提高到71.78 MPa,缺口...用硅烷偶联剂KH550和二苯甲烷二异氰酸酯(MDI)分别对磨细玻璃纤维(MGF)进行表面改性(即KMGF,M-MGF),采用熔融法制备PA6/MGF复合材料。实验结果表明:PA6/M-MGF复合材料中M-MGF质量分数为20%时,拉伸强度从65.82 MPa提高到71.78 MPa,缺口冲击强度从11.86 k J/m2提高到23.73 k J/m2,增强增韧作用优于PA6/K-MGF复合材料;摩擦磨损性能研究发现,PA6/M-MGF复合材料的摩擦因数随着M-MGF质量分数的增加而下降;PA6/M-MGF和PA6/K-MGF复合材料的磨损率的变化趋势一致。展开更多
