METHOD FOR PRODUCING A NONWOVEN ITEM, NONWOVEN ITEM AND HYGIENE ARTICLE

A method for producing a nonwoven element particularly for hygiene products, has at least the following steps: forming a fibrous web sheet with a width direction extending transverse to the production direction and a thickness direction perpendicular thereto by supplying staple fibers from at least a first group which are formed from a thermoplastic material, consolidating the fibrous web sheet to form a nonwoven web by heating exclusively a first side of the fibrous web sheet through contact with a heated surface such that the staple fibers of the first group are partially melted, and cooling the nonwoven web.

Lobed tubular piece made of a composite with unidirectional fibers

A method for manufacturing a fibrous tubular structure including lobes, in which fibers are draped/deposited on a mandrel having a shape corresponding to that of the fibrous structure, includes draping/deposition carried out such that at least one group of fibers has a same orientation with respect to the axis (A) of said fibrous structure, then, the fibers having been draped over an angular sector less than the total periphery of the mandrel, one of the ends of the fibrous structure is separated from the mandrel in order to allow the continuation of the draping on the same mandrel.

CHARGEABLE CORE/SHEATH-STRUCTURED FIBER, NONWOVEN FABRIC OBTAINED FROM SAID FIBER, COMPOSITE NONWOVEN FABRIC, NONWOVEN FABRIC PROCESSED ARTICLE, AND METHOD FOR PRODUCING NONWOVEN FABRIC PROCESSED ARTICLE
20230122322 · 2023-04-20 ·

The present invention provides a chargeable sheath/core-structured fiber that contains a polypropylene-based resin as a main resin, wherein the sheath part contains (a) a carboxylic anhydride-modified polyolefin and (b) at least one antioxidant selected from the group consisting of a combined antioxidant a phenolic antioxidant and a phosphorus-based antioxidant, and sulfur-based antioxidants; and (c) an oil containing a polyoxyalkylene alkyl ether represented by the general formula (I) as a finishing oil is deposited on the outer surface of the sheath part, and that can satisfy heat resistance and charge retainability. (In the formula, R.sup.1 represents a saturated or unsaturated aliphatic hydrocarbon group having 10 to 30 carbon atoms; R.sup.2 represents a hydrogen atom or a methyl group; and k is an integer of 1 to 4.)

LINER FOR UPHOLSTERED FURNITURE
20230068055 · 2023-03-02 ·

A liner, comprising a layered material in which a carded nonwoven wadding is thermally bonded to a thin carded nonwoven top layer, for upholstered furniture. In the liner, a high proportion of the staple fibers in the top layer are thin bi-component binder fibers. Further, at least 20 wt % of the staple fibers in the wadding is thick staple fibers. Furthermore, also the wadding comprises bi-component binder fibers.
