【摘要】 为减轻防刺服的质量,同时增加其穿着舒适性,采用涤纶间隔织物与防刺材料结合的方式制作复合防刺织物。通过对涤纶间隔织物进行压缩测试和对复合织物进行刺割测试,探究间隔织物厚度、间隔丝密度、织物层数对其缓冲性的影响,同时比较了纯防刺材料与不同结构间隔织物防刺材料的防刺效果。研究发现:间隔丝密度越大、织物厚度越小,间隔织物单位厚度的缓冲性越好,当涤纶间隔织物厚度为6. 7 mm、间隔丝密度为9 744根/(0. 01 m~2)时,缓冲性能最好,为25. 1 J/m;使用2层涤纶间隔织物叠加时,间隔织物单位厚度的缓冲性最好,能量吸收为31. 9 J/m;当间隔织物置于防刺材料底部时,在刺割受力最大值附近力的方差约为纯防刺材料的50%,此时缓冲效果最好。更多还原

【Abstract】 In order to reduce the weight of stab-resistant clothing and increase the wearing comfort,stabresistant 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. 7 mm and the density of spacer yarn is9 744 yarns/( 0. 01 m~2),the buffering property is the best,which is 25. 1 J/m. The buffering of unit thickness is better when the polyester spacer fabric is superimposed with two layers,energy absorption reaches 31. 9 J/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.更多还原
