SMS非织造材料抗菌整理及工艺优化

摘要

采用含特殊杂环化合物的抗菌整理剂对SMS非织造布进行抗菌整理。采用了正交实验设计方法，主要考虑整理剂浓度、整理剂温度，浸渍时间，烘燥温度、烘燥时间五个因素，各因素分别取四水平，共设计了16组实验。采用极差分析方法，分析了整理剂的浓度、整理剂温度，浸渍时间，烘燥温度、烘燥时间五个主要因素对抗菌整理效果的影响和显著次序。并以测量抑菌环大小的方法评价抗菌性能，得出了最佳整理工艺：整理剂浓度30g/L，整理剂温度43℃，浸渍时间20min，烘燥温度100℃，烘燥时间180s，同时比较了整理前后试样在强力、透湿性、透气性、悬垂性等方面的差异，经整理后非织造布的透气性、悬垂性并没有太明显的变化，但其强力及透湿性降低，说明经抗菌整理后的非织造布在穿着耐久性方面有所下降，但是经抗菌整理后的非织造布主要用于医用防护方面，且大多为一次性使用，虽然整理后穿着耐久性下降，但能达到较好的抗菌效果，这一点仍然可以接受。

Research on Antibacterial Finishing of the SMS non-wovens and the process optimization

Abstract

Using special heterocyclic compounds-based antibacterial finishing agent for SMS non-woven antibacterial finishing.Orthogonal experimental design is used. We mainly consider five factors: finishing agent concentration,finishing agent temperature,dipping time,drying temperature,drying time,four levels of each factor were taken,a total of 16 experiments designed. Range analysis method is used to analyze finishing effect and significant sequence to the non-woven. The five factors: finishing agent concentration, finishing agent temperature, dipping time,drying temperature,drying time. And to measure the bacteriostatic ring diameter to evaluate antibacterial properties,the optimum finishing process: the concentration is 30g / L, temperature is 43℃,dipping time is 20min,drying temperature is 100℃,time is 180s,the sample was also compared before and after finishing in the strength,water vapor transmission,air permeability,drapebilily,the finished non-woven fabric air permeability and drapebilily change a little,but its strength and water vapor transmission decrease,indicating the antibacterial finished non-woven fabric declines in durability,but the post-finishing non-woven is used in medical protection mainly,and mostly used once,although the antibacterial finished non-woven fabric declines in durability,we can achieve good antibacterial effect,so that is acceptable.
