COMBINATION TWISTS FOR PAPER MACHINE FELTS AND PROCESS FOR THE PRODUCTION THEREOF

摘要

Combination twisted yarn for felt of a paper machine and manufacture method are provided to improve elasticity in a direction of thickness, compressibility, and absorptive capacity during shelf life. Base fabric contains at least one of combination yarns of filaments manufactured out of polyamide and thermoplastic polyurethane. The base fabric is useful for a coating material for a paper machine or textile for another industrial process. The combination yarn is obtained by the steps of: supplying the polyamide and the thermoplastic polyurethane monofilament to a twisting machine at velocity of 5-50m/min.; and then twisting the supplied monofilaments on over 0.1cN/tex, preferably on 0.2-4cN/tex and most preferably on tension of 0.3-0.8cN/tex.
