聚酯纤维非织布(简称非织布)是以高强低伸棉型涤纶纤维和热粘结聚酯纤维为原料,用热轧粘合法制造的。随着工业生产的发展,用非织布代替医药纱布,制造各类一次性手术在、口罩,妇女卫生巾、婴儿尿布等用途十分广泛。其中含有有害于人体健康的游离酚。但目前对非织布中游离酚的测定尚无完善的分析方法,本文采用NaOH碱性溶液浸泡非织布,然后根据水体中酚的测定(4-氨基安替
Polyester non-woven fabric (referred to as non-woven fabric) is a high strength and low stretch polyester fiber and thermal bonding polyester fiber as raw material, with hot-rolled adhesion method. With the development of industrial production, non-woven fabric instead of medical gauze, making all kinds of disposable surgery, masks, women’s sanitary napkins, baby diapers and so a wide range of uses. Which contains free phenol that is harmful to human health. However, there is no perfect analytical method for the determination of free phenols in non-woven fabrics. In this paper, NaOH alkaline solution is used to soak non-woven fabric, and then based on the determination of phenol in water (4-aminoantipyryl
