  • Water vapour permeable and water resistant film was laminated to made footwear woven fabric and non-woven fabrics by screen type with thermosetting reactive hot melt adhesive. Optimum conditions of each process were investigated, and the properties of film laminated fabric with optimum conditions are evaluated. The results are as follows. Thermosetting reactive polyurethane hot melt is retain proper heat resistance differently thermoplastic hot melt. Optimum melting adhesive process conditions are as follows ; drum temperature $95^{\circ}C$, hose temperature $97^{\circ}C$, feeding pipe temperature $100^{\circ}C$, screen temperature $105^{\circ}C$, pressure of opposite roller $1kgf/cm^2$, pressure of laminating roller $3kgf/cm^2$, finishing speed 15 m/min, melting temperature $120^{\circ}C$, cooling time 20 s, pressing temperature $130^{\circ}C$, pressing time 30 s. As the thickness of film was increased, the water vapour permeability was decreased but water resistance was increased, and the effect of film is dominant over all the others in the air permeability.

  • In this study, polyurethane hot melt adhesive containing ester groups was synthesized. Three kinds of chain extenders were used to find out the best chain extender. Results showed that adhesive containing 1,4-butanediol as a chain extender exhibited the highest peel strength among them. Also, it was found that there existed the optimum molecular weight of 1,4-butanediol containing adhesive for make the highest peel strength.. Moreover, hot melt adhesive containing 1,4-butanediol chain extender was applied to various kinds of textiles substrate such as cotton, polyester, and urethane coated polyester textiles to study the effects of different substrates on the peel strength and water resistance at $60^{\circ}C$. It was found that cotton substrate showed the highest peel strength and urethane coated polyester substrate showed the highest resistance on $60^{\circ}C$ water.
