摘要
通过对三种非织造布在热拉伸中的收缩率、伸长率、断裂强度的测试,得出三种非织造布在热拉伸过程中,断裂强度随着拉伸次数的增多而增大,当增加到一定程度后又逐渐下降。收缩率和伸长率随着次数的增多而增大,最后趋于一个稳定的值。
By testing three non-woven fabrics shrinkage rate.elongation percentage and breaking strength during hot stretch,we got the conclusion that breaking strength increased as stretch frequency increased,but when it increased to a certain degree,it would gradually decrease,shrinkage rate and elongation percentage increased as stretch frequency increased, at last they tended to a stable numerical value. In this paper,we also analyzed the reasons a-mong them.
