【摘要】：在我國(guó)以及世界上大多數(shù)國(guó)家人們所面臨的主要人身傷害包括刀具和其它尖銳類器具造成的刺傷、割傷及劃傷。對(duì)于應(yīng)用于防護(hù)服裝的柔性防刺材料,目前還存在著厚重板硬,透濕性、透氣性差等一系列缺點(diǎn),因此本課題從防刺材料的結(jié)構(gòu)、原料及加工工藝出發(fā),在保證防護(hù)性的基礎(chǔ)上提高材料的服用性能,使其應(yīng)用于防刺服裝時(shí)具備更加良好的隱蔽性及舒適性。本課題在綜合比較多種織物組織結(jié)構(gòu)的基礎(chǔ)上,選擇柔性最好的針織結(jié)構(gòu)與抗剪切性最好的非織造結(jié)構(gòu)進(jìn)行復(fù)合。在高性能纖維原料上選擇密度最小且柔軟順滑的超高分子量聚乙烯纖維,另選擇吸濕性很好的黏膠纖維和PET-PA6雙組分橘瓣纖維改善加工過(guò)程中的靜電現(xiàn)象并提高材料的透濕性能。加工方法是采用超高分子量聚乙烯長(zhǎng)絲直接加捻織造成的1+1羅紋織物作為基布,將黏膠長(zhǎng)絲和超高分子量聚乙烯長(zhǎng)絲通過(guò)多管道間隔輸送長(zhǎng)絲鋪網(wǎng)的方法鋪放在基布上,并覆以PET-PA6雙組分橘瓣纖維水刺布,采用預(yù)針刺和水刺工藝加以復(fù)合制得長(zhǎng)絲加筋非織造材料。該材料將針織線圈結(jié)構(gòu)的優(yōu)良彈性和"鎖住"刀尖的特點(diǎn)與非織造布的抗剪切性能相結(jié)合,將超高分子量聚乙烯纖維的高強(qiáng)度高模量和粘膠纖維的高吸濕性、橘瓣纖維的導(dǎo)濕性相結(jié)合,使非織造材料的抗靜態(tài)穿刺性能提高近2倍,動(dòng)態(tài)穿透厚度減少10.95mm,抗彎模量減少約75%,懸垂系數(shù)降低19.73%,透濕性能提高30%,可見(jiàn)該加筋非織造材料具有優(yōu)良的防刺性和舒適性。另外,對(duì)防刺層采取邊緣漸薄間隔固定的處理技巧,對(duì)防刺服的結(jié)構(gòu)進(jìn)行優(yōu)化設(shè)計(jì),提高其隱蔽性。最終,本課題采用加筋非織造復(fù)合材料制作的新款防刺西服馬甲總重1.32kg,厚度5.28mm~19.17mm,比原防刺背心輕0.96kg,薄6.25mm。滿足GA68-2008《警用防刺服》和美國(guó) NIJ Standard-0115.00《Stab Resistance of Personal Body Armor》的一級(jí)防護(hù)標(biāo)準(zhǔn),外觀新穎,柔軟透氣,舒適性好,可搭配西裝穿著,隱蔽性佳。
[Abstract]:In our country and most of the countries in the world, the main personal injuries that people face include stab wounds, cuts and scratches caused by cutting tools and other sharp instruments, as well as flexible anti-prickly materials used in protective clothing. At present, there are a series of shortcomings such as heavy plate hard, moisture permeability, poor gas permeability and so on. Therefore, this subject is based on the structure, raw materials and processing technology of anti-prickly materials, and improves the wearability of the materials on the basis of ensuring the protection. It has better concealment and comfortableness when it is used in the burn-proof clothing. This subject is based on the comprehensive comparison of the fabric structure of many kinds of fabrics. Choose the best knit structure with the best shear resistance of nonwovens and choose the minimum density and soft smooth ultra high molecular weight polyethylene fiber on the high performance fiber raw material. Another good hygroscopic viscose fiber and PET-PA6 two-component orange flap fiber was chosen to improve the electrostatic phenomenon and improve the moisture permeability of the material during the processing. The processing method is to adopt UHMWPE filament directly. Twisting 1. 1 rib fabric as substrate. The viscose filaments and UHMWPE filaments were placed on the substrate and covered with PET-PA6 bicomponent orange fiber spurs. The filaments reinforced nonwovens were prepared by the combination of pre-needling and spurs. This material combines the excellent elasticity of the knitting coil structure and the characteristics of "locking" the tip of the knife with the shear resistance of the nonwovens. By combining the high strength and high modulus of UHMWPE fiber with the high moisture absorption of viscose fiber and the moisture conductivity of orange flap fiber, the static puncture resistance of nonwovens was improved nearly 2 times. The dynamic penetration thickness is reduced by 10.95mm, the flexural modulus is reduced by about 75mm, the drape coefficient is reduced by 19.73mm, and the moisture permeability is improved by 30%. It can be seen that the reinforced nonwoven material has excellent burn-resistance and comfort. In addition, the anti-punching layer is treated with the technique of thinning and fixing the edge, and the structure of the anti-punching suit is optimized to improve its concealment. The total weight and thickness of the new vest made of reinforced nonwovens are 1.32 kg and 5.28 mm and 19.17 mm respectively, which are 0.96 kg lighter than the original vest. Thin 6.25mm. satisfying GA68-2008 < police burr suit] and NIJ Standard-0115.00 < Stab Resistance of. The primary protection standard for Personal Body Armor >. The appearance is novel, soft and breathable, comfortable, can match suit to wear, concealment is good.
