摘要:
A nano technology process for the manufacture of a fabric that comprises fibers, such as man-made fibers, cotton fibers or cellulose fibers, which are essentially hydrophilic, with improved moisture-management performance, in which the fibers are individually encapsulated with a nano chemistry water-repellant surface.

Disclosed herein are overmolded polyamide composites structures and processes for their preparation. The disclosed overmolded composite structures comprise i) a first component having a surface, at least a portion of which is made of a surface resin composition, selected from polyamide compositions comprising a blend of two or more fully aliphatic polyamides having a melting point of at least 250° C., and comprising a fibrous material being impregnated with a matrix resin composition, ii) a second component comprising an overmolding resin composition, adhered to said first component over at least a portion of the surface of said first component, and wherein the matrix resin composition is selected from polyamide compositions comprising a one or more fully aliphatic polyamides having a melting point of at least 250° C.
摘要:
A salt sensitive polymeric binder for use in fibrous webs, where the binder contains a copolymer of carboxylic acid monomer units, acrylate monomer units, and N-alkyl acrylamide units. The copolymer is neutralized at least to the point where it is water soluble. The binders are particularly suitable for strengthening non-woven fibrous webs in disposable articles such as wet-wipes, personal care products, diapers, and the like.

The present invention relates to the field of composite structures, overmolded composites structures and processes for their preparation, particularly it relates to the field of polyamide composite structures. The disclosed composite structures have a surface, which surface has at least a portion made of a surface polyamide resin composition, and comprise a fibrous material selected from non-woven structures, textiles, fibrous battings and combinations thereof, said fibrous material being impregnated with a matrix resin composition, wherein the surface polyamide resin composition is selected from polyamide compositions comprising a blend of a) one or more semi-aromatic polyamides (A) containing repeat units derived from aromatic dicarboxylic acids and aliphatic diamines, and b)one or more fully aliphatic polyamides (B) selected from the group consisting of polyamides containing repeat units derived from aliphatic dicarboxylic acids and aliphatic diamines, polyamides containing repeat units derived from aliphatic aminocarboxylic acids, and polyamides derived from lactams.
摘要:
The invention relates to a method of treating a fabric involving metal peroxide impregnation. The invention is characterised in that a fabric, e.g. pre-bleached and/or desized hydrophilic fabric having a weft (or inversely a warp) comprising natural or synthetic cellulosic fibres, is subjected to the following: impregnation (I) in a metal peroxide leaving the weft (or inversely the warp) free for a period necessary for the swelling of the fibre forming the weft (or inversely the warp) of the fabric and for the modification of the cellulose; at least one relaxation operation without weft (or inversely warp) tension with the passage of air, during which the weft (or inversely the warp) swells and takes the form of a spring, following shrinkage; at least one rinsing operation; at least one washing operation; and at least one squeezing operation. The invention also relates to the elastic fabrics thus obtained and to the machines used to implement said method.
