碱氧处理对阳离子可染中空聚酯针织物服用性能的影响

为分析阳离子可染聚酯中空短纤维与天然纤维混纺织物进行碱精练和氧漂白加工的可行性，研究了氢氧化钠、过氧化氢、氢氧化钠与过氧化氢协同作用对纤维服用性能和机械性能的影响。结果表明，氢氧化钠和过氧化氢单独处理均会对聚酯织物的保暖性、透湿性和顶破强力产生显著影响。在中空结构不被破坏的前提下，正交试验结果表明氢氧化钠和过氧化氢具有协同作用，可加剧聚酯织物保暖性和顶破强力的损伤，且过氧化氢质量浓度对保暖性的影响比氢氧化钠质量浓度更显著。

Effect of alkaline-oxygen treatment onwearabilitiesof cationic dyeablehollow polyester knittedfibers

An investigation on the feasibility of alkali scouring and oxygen bleaching of cationic dyeable polyester hollow stable fiber / natural cellulosic fiber blended fabrics studied the effect of sodium hydroxide, hydrogen peroxide, synergetic effect between sodium hydroxide and hydrogen peroxide on the wearabilities and mechanical properties of the polyester. The results showed that warmth retention, water-vapor permeation and bursting strength of polyester fabric would be remarkably affected by sodium hydroxide treatment and hydrogen peroxide treatment, respectively. Based on the hollow structure not be destructed, the results of orthogonal experiment indicated that sodium hydroxide and hydrogen peroxide had a synergetic effect on the damage to warmth retention and bursting strength of polyester fabric, and the effect of hydrogen peroxide concentration on the warmth retention was more notable than that of sodium hydroxide concentration.
