摘要
以废棉纤维、聚丙烯(PP)纤维和麻纤维为原料,采用非织造技术加工成不同结构性能的针刺非织造材料,用作公路护坡生态毯。以纤维配比、层叠结构和针刺密度为因素,以非织造生态毯纵/横向断裂强力、纵/横向断裂伸长率、透水水流量和表面摩擦因数为考核指标,通过正交试验设计方案优选加工工艺,得出最佳工艺组合是A2B3C1。试验结果表明:最佳配比为m(棉)∶m(麻)∶m(PP)=2∶3∶5;最佳结构为棉、PP和黄麻纤维分别单独成网,按黄麻在第一层,PP纤维在中间,棉为基层叠加的三层结构;最佳针刺密度为325刺/cm2。在上述条件下制得的生态毯性能最好,能够满足生态护坡的要求。
Waste cotton and PP fiber and jute be as raw materials,needle-punched nonwovens were produced with various structure properties by nonwoven processing to be used as eco-felts of slope road.The factors be fibers ratio and laying structure and needle-punch density of nonwoven eco-felts,test index be horizontal and longitudinal breaking strength and breaking elongation rate and water leakiness and surface friction divisor,and throughout orthogonal test to design and optimize processing technique and the best technique was obtained.The test result demonstrated that the best fiber ratio of cotton/jute/PP was 2/3/5,and the best structure was jute as surface layer and cotton as base layer and PP in the middle,the best needle-punch density was 325 needles per square centimeter.The eco-felts produced on above technique had good property and could meet the needs of eco-protect on slope road.
