Abstract ㊀In order to reduce the weight of stab-resistant clothing and increase the wearing comfort,stab-resistant fabric was manufactured by combining the polyester spacer fabric with the stab-resistant material.The compressing test of polyester spacer fabric and the pricking test of composite fabric were carried out.The effects of fabric thickness,density of spacer yarn and number of fabric layers on stab-resistant properties were discussed.The stab resistant effect of spacer fabric combined with the anti-stab-material and pure stab-resistant material were compared.It is found that the thicker the spacer filament is and the lower thickness of the spacer fabric is,and the better the compression property of the spacer fabric unit thickness is.When the thickness of polyester spacer fabric is 6.7mm and the density of spacer yarn is 9744yarns /(0.01m 2),the buffering property is the best,which is 25.1J /m.The buffering of unit thickness is better when the polyester spacer fabric is superimposed with two layers,energy absorption reaches 31.9J /m.The buffering effect of the spacer fabric is better when it is placed at the bottom of the anti-stab material,and the variance of the force near the maximum value is about 50%of the pure material.Keywords ㊀stab-resistant fabric;spacer fabric;coating fabric;buffering effect;antipuncture property 收稿日期:2018-06-19㊀㊀㊀修回日期:2018-12-24基金项目:国家重点研发计划资助项目(2016YFC0802802)
