  • Patent number: 5798167
    Abstract: There is disclosed a thermally bonded spunbond web of thermoplastic filaments and a nonwoven fabric laminate comprising an internal layer of meltblown thermoplastic microfibers sandwiched between two layers of spunbond thermoplastic filaments. The spunbond web and the spunbond layers of the fabric laminate consist of thermoplastic filaments which are formed from a mixture of a thermoplastic polymer and an effective amount of a nucleating agent. The layers are bonded by thermal spot bonding. In the preferred embodiment, the thermoplastic polymer is polypropylene with a melt-flow rate of at 230.degree. C. of or greater than 12 grams per ten minutes. Also in the preferred embodiment, the nucleating agent constitutes from about 0.1 to 0.3 percent by weight of the mixture of polypropylene and nucleating agent.

  • Patent number: 5652051
    Abstract: There is disclosed fibers and fabrics formed from a polymer which is a "hand enhancing" polymer. The "hand enhancing" polymer is a copolymer of polypropylene which contains ethylene, 1-butene, or 1-hexene or a terpolymer of propylene, ethylene and butene. If the polymer is an ethylene copolymer, the copolymer may be random or random and block and the ethylene must be present in an amount between greater than 5 and 7.5 weight percent of the copolymer. If the copolymer contains 1-butene, it must be present in an amount between 1 and 15.4 weight percent of the copolymer. If the copolymer contains 1-hexene, it must be present in an amount between 2 and 5 weight percent of the copolymer. If the polymer is a terpolymer of propylene, ethylene and butylene, the polypropylene is present in an amount between 90 and 98 weight percent, the ethylene is present in an amount between 1 and 6 weight percent and the butylene is present in an amount between 1 and 6 weight percent.
