Non-woven textile articles comprising bicomponent fibers and method of manufacture

摘要

Fibers comprising 10 to 100% of bicomponent fibers, composed of a core polymer covered by a sheath polymer, are heated to a temperature between the softening point and the melting point of the sheath polymer for 5 seconds to 5 minutes at a pressure of 0 to 2000 psi until the fibers are bonded together. The products are used for drive belts and seals, nib felts for marking pens, filter cloths for plate and frame filters, filtration cartridges, stamp pad ink reservoirs, and battery separators.
