纸尿裤面层的抗菌和透气性研究

Study on Antibacterial and Air permeability of Paper Diaper Surface

具有抗菌性对于纸尿裤来说是一个重大的突破,而绿色无毒无害,是婴儿用品的必备要求^([1])。采用绿色无害的壳聚糖作为抗菌剂,对婴儿纸尿裤面层材料进行浸渍后整理,使非织造材料上包覆着壳聚糖^([2]),对纸尿裤面层材料进行抗菌整理。得出最优方案的壳聚糖浓度为1.0%,抑菌率达到90%以上,透气性和柔软性都比浓度更高的壳聚糖溶液整理工艺参数更好。

It is a big breakthrough for paper diapers to have antibacterial. Green, non-toxic and harmless are the essential require- ments for baby. The surface layer of paper diaper was finished with chitosan as antibacterial agent, so that non-woven materials were coated with chitosan. Antibacterial finishing of the surface layer of paper diaper were carried out. The optimal concentration of chitosan was 1.0 %, the antibacterial rate was above 90 %. Permeability and softness at concentration of 1% was better than the chitosan solution with higher concentration.
