Improved Adhesion of a Thermoplastic Polymer to Nonwoven Substrates.
Abstract
The objective of this work was to develop coated fabrics with high adhesion between polymer and substrate to minimize delamination under severe climatic conditions and to provide high-component peel strength of heat-sealed seams. Polyether urethane was modified with olive drab pigment, UV light-absorbers and a silicone bubble-dispersing agent to improve the resistance to aging of coated surfaces. The pigment improved coating bond to the nylon substrate, heat-seal peel strength and resistance to 150 hours exposure in the Weather-Ometer. Application of multiple thin polymer coats successfully eliminated bubble formation during the coating application. Selected weapon accessory items were designed and fabricated with high-strength heat seals from the laboratory prepared material. (P.S.-PL)
