  • Textile laminate
    Publication number: 20070149082
    Abstract: A textile laminate includes a hydrophobic membrane, an inner fabric layer and an outer fabric layer sandwiching the hydrophobic membrane. The hydrophobic membrane has a plurality of tangled polymer fibers, a plurality of pores among the polymer fibers, and a plurality of adhesive powder attached on the polymer fibers on the top and bottom surfaces. The grain size of each adhesive powders is small enough to remain the pores without obstructing permeability. The pores in the PTFE film are water vapor permeable and liquid water impermeable.
    Type: Application
    Filed: February 16, 2007
    Publication date: June 28, 2007
    Inventors: Cheng-Wu Ying, Chi-Heng Lee
