Title:
HEAT-RESISTANT NON-WOVEN FABRIC AND PRODUCTION THEREOF
Document Type and Number:
Japanese Patent JP2602166
Kind Code:
B2
Abstract:
PURPOSE: To obtain a heat-resistant non-woven fabric having high air permeability and flexibility by using polyester fibers and/or polyphenylene sulfide fibers in an extremely low blending rate and pressing the produced web with a low pressure.
CONSTITUTION: Wholly aromatic polyamide fibers as a main component are blended with 1-3wt.% of polyester fibers and/or polyphenylene sulfide fibers, and the formed web is heated with the irradiation of far IR light and subsequently pressed with a low pressure to produce the heat-resistant non-woven fabric in which the cross points of the fibers composing the non-woven fabric are thermally adhered.
