FOURDRINIER PAPERMAKING BELT

摘要

A woven Fourdrinier Papermaking Belt made of synthetic polyester cross-machine direction strands and machine direction strands, in which the cross-machine direction strands have a low modulus of elasticity measured in their woven heat-set condition and the machine direction strands have a higher modulus of elasticity, both modulus measurements being made at an extension of the strand at which the crimp has just been substantially pulled out.
