摘　　要：为进一步提高户外面料的防暴雨性能,通过分析防暴雨面料基材结构对户外面料防暴雨性能的影响,优化无氟防水整理工艺,测试面料的防暴雨性能,确定防暴雨面料基材结构及无氟防水整理工艺。结果表明:在确定面料基材其他结构参数的情况下,无弹和机械纬弹面料的防暴雨性能相较于机械四面弹更优异;防暴雨性能随着纱线纤度和面料经纬密的增加而增加,面料组织结构对防暴雨性能影响较小。选定机械纬弹、纱线纤度为167 dtex、经纬密度为376×300根/(10 cm)的平纹面料作为防暴雨面料基材,对其进行防水整理,整理工艺为无氟防水剂R3质量浓度40 g/L、交联剂TF-569P质量浓度12 g/L、带液率60%,一浸一轧,焙烘温度170℃,焙烘时间90 s。经防水整理后,洗前防泼水评分为100分,耐水洗测试20次后防泼水评分仍然可保持在95分,进一步对单布进行邦迪斯门防暴雨测试,测试10 min时的防水等级可达3~4级,吸水率为12.5%,透水量为10 mL。该研究结果可为防暴雨户外运动面料的制备提供参考。To further improve the rainstorm-proof performance of outdoor fabrics,the influence of substrate structure of rainstorm-proof fabrics on rainstorm-proof performance of outdoor fabrics was studied,the fluoride-free waterproofing process was optimized,the rainstorm-proof performance of the fabrics was tested,and substrate structure and fluorine-free waterproofing process of the rainstorm-proof fabrics were finally confirmed.The results showed that:in the case of determining other specifications of the fabric substrate,the elasticity-free fabrics and mechanical weft elasticity fabrics had better rainstorm resistance than fabrics with mechanical four-sided elasticity;the rainstorm resistance increased with the increase of linear density and fabric warp and weft density,and the fabric structure had less effect on the rainstorm resistance.Plain weave fabrics with mechanical weft elasticity,a linear density of 167 dtex,and a warp and weft density of 376×300 pieces/(10 cm)were selected as the base material of rainstorm-proof fabrics,and the waterproofing was carried out.The waterproofing process required a the mass concentration of fluorine-free waterproof agent R3 of 40 g/L,a mass concentration of cross-linking agent TF-569P of 12 g/L,and a liquid carrying rate of 60%by one dipping and one rolling under a baking temperature of 170℃for 90 s.After waterproofing,the water repellency score was 100 points,and after 20 washable tests,the water repellency score could still be maintained at 95 points.Further Bundesmann rainstorm-proof tests were performed on single-layer fabrics,and it was found that the waterproof level could reach the third or fourth grade after 10 min,the water absorption rate was 12.5%,and the water permeability was 10 mL.The research results can provide reference for the preparation of rainstorm-proof outdoor sports fabrics.
