In order to verify the difference of impact resistance of the sports protective suit samples made of different veils and apply them to the protective clothing, in this study, 5 different materials including 7.8tex(70D)/48F nylon, 7.5tex(70D)/72F Cooldry, 7.8tex(70D)/48F trefoil nylon, 7.8tex(70D)/48F round-hole nylon, and 40S cotton are used as veil materials. 2.2 tex(20D)/4.4 tex(40D) nylon spandex covered yarn is used as base material. The representative 1+3 rib structure of weft is taken as the organizational structure. The single factor analysis method is used to test the impact resistance, tensile elasticity, plastic deformation rate, air permeability, moisture absorption, moisture permeability, bursting strength, and other performance of the sports protective suit. The results show that the sports protective suit made of 7.8 tex(70D)/48F trefoil nylon veils has the highest impact penetration energy, reaching 26.2J, and there is a significant correlation between surface density and impact penetrability; 7.8 tex(70D)/48F trefoil nylon veils have the highest permeability, evaporation, and moisture permeability among the 5 veils; the moisture content of the fabric made of 7.5 tex(70D)/72F Cooldry veil is the highest, which is 5.84%, and that of the sports protective suit sample made of 7.8 tex(70D)/48F trefoil nylon is 5.36%. According to the analysis of the deformation rate, the transverse and longitudinal deformation rates of sports protective suit samples made of 7.8 tex(70D)/48F trefoil nylon are 5.1% and 6.6% respectively, which is the smallest among the 5 kinds of veers. After the analysis of the jacking property, it is found that 7.8 tex(70D)/48F trefoil nylon veils have the largest breaking strength. Taking all the indexes into consideration, it is found that using 7.8tex(70D)/48F trefoil nylon as the veil can increase the wear-ability and protective performance of protective clothing.
