超细涤纶织物超级仿绸性能优化研究

比较了等离子体改性、碱减量改性以及等离子体改性后再烧碱改性的超细涤纶织物的性能.采用烧碱对等离子体改性后超细涤纶织物进行超级仿绸整理,以质量损失率、润湿性、断裂强力、硬挺度、悬垂度、透气性等指标表征超级仿绸性能.采用正交分析法优化了烧碱超级仿绸整理工艺处方和工艺条件.结果表明:经过超级仿绸整理后,超细涤纶织物强力变化不大,具有真丝绸手感与风格,超级仿绸整理最佳工艺为:烧碱浓度4.5 g/L,促进剂浓度0.8 g/L,时间30 min,温度60℃.

Study on super silk-like performance optimization of ultra-fine polyester fabric

The performances of ultra-fine polyester fabric after plasma modification,alkali deweighting modification as well as firstly plasma modification and then caustic soda modification are compared.The plasma modified ultra-fine polyester fabric is super silk-like finished by use of caustic soda and characterized by weightlessness rate,wettability,breaking strength,stiffness,drape degree,air permeability and other index indicators.And orthogonal analysis is used to optimize the technological conditions and processing of the caustic soda super silk-like finishing.The result indicates that ultra-fine polyester fabric remains less changable in strength and is of pure silky feel and style after super silk-like finished.The best process technology for the super silk-like finishing is that the concentration of the caustic soda is 4.5g/L with promoting agent concentration being 0.8g/L as well as 30 mins time duration and 60℃ temperature.
