海藻酸盐纤维面膜基材的制备与性能研究

用海藻酸钙纤维分别与竹纤维、天丝纤维、棉纤维等混合后制备水刺无纺布,测试了各种无纺布面膜基材在含有透明质酸钠、羧甲基纤维素钠、羧甲基甲壳胺、聚乙烯醇等水溶液的吸液率,以及对水溶液中铜离子、铅离子的吸附性能。结果显示,海藻酸盐面膜基材的吸液率受精华液中阴离子含量的影响,加入透明质酸钠、羧甲基纤维素钠、羧甲基甲壳胺等阴离子型水溶性高分子可有效提高面膜的吸液率、改善面膜的保湿性能。海藻酸钙纤维对铜离子和铅离子有很强的吸附性能,使用在皮肤上可吸收皮肤中的重金属离子,在功能性面膜领域有很高的应用价值。

Preparation and Property Analysis of Alginate Fiber Mask Substrate

Calcium alginate fibers were mixed with bamboo fibers, tencel fibers and cotton fibers to prepare spunlaced nonwoven fabric.Experiments were carried out to test the absorption rates in aqueous solutions of various nonwoven fabric mask substrates containing hyaluronic acid, carboxymethyl cellulose, carboxymethyl chitosan and poly-vinyl alcohol and their absorption properties for copper and lead ions.The results showed that absorption rate was influenced by the content of anion in essence liquid, adding anionic polymers such as hyaluronic acid, carboxymethyl cellulose and carboxymethyl chitosan could increase the absorption capacities of the face masks and improve their moisturizing performances.Calcium alginate fibers also had strong absorption capabilities for copper and lead ions to absorb heavy metals ions in the skin, which made them valuable in functional face mask materials field.
