BICOMPONENT SPANDEX
An elastic multiple component fiber comprising a cross-section, wherein at least a first region of said cross-section comprises a polyurethaneurea composition; and comprising a second region.
Extensible nonwoven fabric
Extensible nonwoven fabrics having improved elongation, extensibility, abrasion resistance and toughness. In particular, embodiments of the invention are directed to extensible spunbond fabrics comprising a polymeric blend of a metallocene catalyzed polypropylene, polyethylene, and a third polymer component.
Sheet for packaging edible meat, and casing for packaging edible meat
A sheet for packaging edible meat is provided that includes a layer A and a layer B thermally adhered to each other. In the sheet, the layer A is a wet-laid nonwoven fabric produced by mixing a first core-in-sheath fiber (a) having a core made of polyester and a sheath made of polyethylene, a second core-sheath fiber (b) having a core made of polyester and a sheath made of a low-melting-point polyester, and an ultrafine polyester fiber (c). The layer B is a spunbonded nonwoven fabric produced from a third core-sheath fiber having a core made of polyester and a sheath made of polyethylene. Also a casing for packaging edible meat is provided that is formed from the sheet for packaging edible meat.
Bicomponent spandex
An elastic multiple component fiber comprising a cross-section, wherein at least a first region of said cross-section comprises a polyurethaneurea composition; and comprising a second region.
Crimped conjugated fiber and non-woven fabric comprising the fiber
The present invention provides a crimped conjugated fiber having a crimpable cross-sectional configuration wherein a cross section of the fiber comprises at least two portions: a portion (a) and a portion (b); the portion (a) comprises a propylene polymer (A) and the portion (b) comprises a propylene/-olefin random copolymer (B); the propylene polymer (A) has Mz/Mw(A) and the propylene/-olefin random copolymer (B) has Mz/Mw(B) wherein the difference thereof is in the range of 0.10 to 2.2; and the propylene polymer (A) has a melting point [Tm(A)] and the propylene/-olefin random copolymer (B) has a melting point [Tm(B)] wherein the difference thereof exceeds 10 C. The present invention also provides a non-woven fabric comprising the crimped conjugated fiber.
Laminates with bonded webs
Laminates with a layer of bonded nonwoven material attached to a layer of film.
Nonwoven webs and multi-component fibers comprising a polydiorganosiloxane polyamide and methods of melt blowing
The present invention pertains to nonwoven webs, and multi-component fibers comprising polydiorganosiloxane polyamide as well as method of making microfibers and multi-component fibers comprising a polydiorganosiloxane polyamide copolymer.
