摘要:

为提高医卫用非织造布产品的使用性能,本文采用NaOH/H2O2一步法对棉纤维进行脱脂漂白,通过正交试验设计,利用极差分析法,确定最佳脱漂工艺,探讨先漂后刺和先刺后漂两种工艺对医卫用全棉水刺非织造材料吸水性、白度、强度、柔软性和透气性的影响。结果表明:最佳脱漂工艺参数组合为:时间60 min,浴比1:30,温度95 ℃;温度对纤维白度和吸水量的影响最大,时间对纤维强度的影响最大;使用最佳脱漂工艺参数得到的全棉水刺非织造布,其厚度、克重和断裂强度有所下降,吸水性明显上升;采用最佳脱漂工艺参数组合制备的先漂后刺全棉水刺非织造布的断裂强度和断裂伸长率较高,而采用先刺后漂全棉水刺非织造布的柔软性、透气性和吸水性更好。

Abstract:

In order to improve the performance of nonwoven fabric used for medical treatment and hygiene, the optimal degreasing and bleaching process was determined by orthogonal test and range analysis which is studied by NaOH / H2O2 one-step method and studied the effects of the Bleaching-to-Spunlaced and the Spunlaced-to-Bleaching process on water absorption, whiteness, strength, softness and permeability of the spunlaced nonwoven fabric. The results show that the optimum parameters are as follows: time 60min, liquor ratio 1:30, temperature 95 ℃. The effect of temperature on fiber whiteness and water absorption was the most significant, and time had the greatest effect on fiber strength. The thickness, weight and tensile strength of cotton spunlaced nonwoven fabric with the best bleaching parameters decreased, and the water absorption increased significantly. The Bleaching-to-Spunlaced nonwoven fabric prepared with this parameter combination has higher tensile strength and elongation, and the Spunlaced-to-Bleaching nonwoven fabric has better softness, permeability and water absorption.

Key words: pure coton nonwovens materials, medical and hygiene textiles, spunlaced method, degreasing and bleaching, water absorption, whiteness
