Study of Adhesion Property between PTFE Films and Polypropylene Spunbond Nonwoven Materials

摘要

The adhesion property of PTFE films and nonwoven materials plays an important role in various applications such as in hygiene and medical field. In order to laminate PTFE films with Polypropylene spunbond nonwovens (PPSN), a treatment on the surface of PTFE film which can improve its wetability is a must. In this paper, normal temperature and lowpressure plasma treatment is used to improve the wetability of PTFE film. In comparison, epoxy resin coated PTFE film is studied as well. At last, the peel strength of nonwoven fabrics laminated with PTFE films by plasma and epoxy resin treatment and their porosity were tested in order to study their adhesive ability.
