  • Textile structures containing linear low density polyethylene binder fibers
    Patent number: 5698480
    Abstract: A fiber comprising at least about 80% by weight linear low density polyethylene and having a melting point >109.degree. C. is disclosed. Also disclosed are thermally consolidated fiber structures comprising (1) at least about 3% by weight, based on the total weight of the structure, of lower melting binder fibers comprising at least 80% by weight linear low density polyethylene, and (2) not more than 97% by weight, based on the total weight of the structure, of nonmelting fibers, or fibers having a melting point higher than the linear low density polyethylene fibers. The fiber structures can be in the form of multifilament yarns, woven or nonwoven textile fabrics, carpets, or laminates. The linear low density polyethylene binder fibers in the structures preferably have a melting point <109.degree. C.
