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.

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.

Nonwoven fabric, a laminated fabric, a nonwoven fabric product, a multicomponent fibre, a web, and a method of producing the nonwoven fabric

A nonwoven fabric comprising a meltspun fiber of a lignin compound. Also claimed a laminated fabric comprising the nonwoven fabric, a nonwoven fabric product comprising the nonwoven fabric, a structured multicomponent fiber comprising a lignin compound, a web comprising a meltspun fiber of a lignin compound and a method of producing a nonwoven fabric by forming a web of meltspun fiber comprising a lignin compound and bonding at least a portion of the fiber in the web to form the nonwoven fabric.

Molded object having nonwoven fibrous structure

To prepare a shaped product comprising a thermal adhesive fiber under moisture and having a fiber aggregate nonwoven structure. In the shaped product, the thermal adhesive fibers under moisture are melted to bond to fibers constituting the fiber aggregate nonwoven structure and the bonded fiber ratio is not more than 85%. The shaped product has an apparent density of 0.05 to 0.7 g/cm.sup.3, a maximum bending stress of not less than 0.05 MPa in at least one direction, and a bending stress of not less than ⅕ of the maximum bending stress at 1.5 times as large as the bending deflection at the maximum bending stress. The moistenable-thermal adhesive fiber may be a sheath-core form conjugated fiber comprising a sheath part comprising an ethylene-vinyl alcohol-series copolymer and a core part comprising a polyester-series resin. Such a shaped product can be used for a building board or the like since the shaped product has a high bending stress although the product is light and has a low density.

Nonwoven Webs With Hydrophobic And Hydrophilic Layers

A nonwoven web for use in an absorbent article is described. The nonwoven web has first and second nonwoven layers. The first nonwoven layer has a first plurality of fibers, an additive disposed, at least in part, on a portion of the first plurality of fibers, a first side and an opposing second side, wherein second side has a plurality of discontinuities. The second nonwoven layer has a second plurality of fibers, a first surface and an opposing second surface, and a plurality of tufts extending through at least a portion of the discontinuities in the first nonwoven layer, wherein the second nonwoven layer is attached to the first nonwoven layer such that at least a portion of the second plurality of fibers are in liquid communication with the first nonwoven layer, wherein the first nonwoven layer is hydrophobic and the second nonwoven layer is hydrophilic.

Hair cleaning implement

A hair cleaning implement in the form of a laminate with surface properties specifically tailored to improve sebum removal from hair. The implement includes a nonwoven material joined to a film to form a laminate and a plurality of discrete protrusions extending from the surface of the nonwoven material. The protrusions are configured to provide the desired surface properties to the implement.

BI-COMPONENT MICROFIBERS WITH HYDROPHILIC POLYMERS ON THE SURFACE WITH ENHANCED DISPERSION IN ALKALINE ENVIRONMENT FOR FIBER CEMENT ROOFING APPLICATION

The present invention provides bi-component core-shell polymeric microfibers for reinforcing concrete comprising as a first component (shell) ethylene-vinyl alcohol (EVOH) polymer and at least one plasticizer, preferably, polyethylene glycol, and as a second component (core) a polymer chosen from a polyamide, a polyester, such as polyethylene terephthalate, and a polymer blend of a polyolefin and an anhydride grafted polyolefin and having an aspect ratio of length to diameter (L/D) or equivalent diameter of from 300 to 1000. The bi-component polymeric microfibers comprise from 5 to 45 wt. % of the first component, are easily processed, and provide fiber cements having improved mechanical properties at relatively low microfiber loadings.
