摘要
常用纺织品透气性的测试标准有ASTM D737—1996和GB/T 5453—1997,分析对比其测试条件和测试结果,考察了织物材料、组织结构、加工方式和水洗次数等因素对织物透气性的影响。结果表明,用ASTM D737—1996与GB/T 5453—1997的测试结果呈现较高的相关性;棉、麻、羊毛等天然纤维和蛋白质纤维织物的透气性好于尼龙、涤纶等合成纤维织物;织物透气性的顺序为:透孔织物>缎纹织物>斜纹织物>平纹织物;前5次水洗后,织物的透气率变化明显,而后逐渐趋于平缓;液氨整理能提高织物的透气性,三防整理会明显降低织物的透气性;焙烘后织物的透气性均比焙烘前有所增加。
Air permeability testing standards of textiles were introduced. Testing conditions and results of ASTM D737-1996 and GB/T 5453-1997 were compared respectively. Effects of material, structure, processing methods and laundering cycles on air permeability of textiles were discussed. Results showed that there was a high correlation between testing results of ASTM D737-1996 and those of GB/T 5453-1997; air permeability of natural fiber fabrics and protein fiber fabrics was better than that of synthetic fabrics. Fabrics were ranked according to air permeability as follows： openwork fabric 〉 satin fabric 〉 twill fabric 〉 plain fabric. Changes in air permeability were obvious in the first five laundering cycles and then became gradual. Liquid ammonia finish could improve air permeability, while water-proof, oil-proof and stain-proof finish would worsen it. Air permeability of fabrics increased slightly after curing process.
