摘要
无纺布置物袋可较好满足人们出行和购物需求,其产品类别繁多,但质量参差不齐.为优选合适的无纺布置物袋,根据置物袋实际使用需求,测试5种常规环保置物袋的拉伸、撕裂、顶破、透气、耐磨和散热性能.得到结论如下:无纺布置物袋的拉伸强力、顶破、撕裂等力学性能随着面密度增加呈指数增加趋势,耐磨性能随面密度呈线性递增,透气性、散热性能与面密度呈对数衰减趋势.30-40 g/m2环保购物袋的性能最优,可满足实际使用要求.
Abstract
The non-woven shopping bags can better meet people's travel and shopping needs,with a wide variety of product categories but varying quality.To select suitable non-woven shopping bags,the tensile,tearing,bursting,breathable,wear-resistant,and heat dissipation properties of 5 conventional environmentally friendly shopping bags are tested based on their actual usage needs.The conclusions are as follows:the tensile strength,bursting strength,tearing and other mechanical properties of non-woven fabric bags increase exponentially with the increase of surface density,the wear resistance increases linearly with the increase of surface density,and the breathability,heat dissipation performance and surface density show a logarithmic decay trend.30-40 g/m2 eco-friendly shopping bags have the best performance and can meet practical usage requirements.
