A material includes nonwoven fibers and a surface modification that crosslinks the nonwoven fibers together. The surface modification can include chemical reactive groups. The reactive groups can be selected from diisocyanates, alcohols, epoxides, imides, amides, imines, amines, diacrylates, disiloxanes and disilazanes. A method of forming the material electrospins fiber material in the form of fibers into a nonwoven material. A surface modification is introduced to the fibers either by modifying the fiber material before the electrospinning or by modifying the fiber surface after the electrospinning. The fibers are crosslinked to form the crosslinked nonwoven material.

A rubber-reinforcing cord (12) of the present invention includes at least one strand. The strand includes at least one filament bundle and a coating provided to cover at least a portion of a surface of the filament bundle. The coating includes a rubber component including at least one selected from the group consisting of carboxyl-modified nitrile rubber and carboxyl-modified hydrogenated nitrile rubber, an isocyanate compound, a bismaleimide compound, carbon black, and a rubber-modified epoxy resin. In the coating, the content of the isocyanate compound is 10 to 50 parts by mass, the content of the bismaleimide compound is 5 to 25 parts by mass, the content of the carbon black is 2 to 18 parts by mass, and the content of the rubber-modified epoxy resin is 5 to 30 parts by mass, with respect to 100 parts by mass of the rubber component.

The present invention relates to a method for providing an anti-microbial and an anti-pilling effect to textiles and for improving dye uptake to textiles. The invention also relates to novel co-polymers to be used in the method of the invention and to novel textiles.

The present invention relates to an adhesive composition including a latex (A), a polyurethane (B), an amine-based adhesion promoter (C), and a water-containing solvent (G). The composition is eco-friendly, has a low risk of fire, and has excellent adhesive strength.

The present invention provides an anti-pilling wool fabric with a coating having pilling resistance and resistance to fiber loss from fabric surface. The coating is formed by a coating formulation including at least two diisocyanates, at least two catalyst, a water dispersing agent, a buffer and water, which provides a polycarbodiimide crosslinker reactive to the relative less reactive groups on polypeptide of the wool fabric and promotes crosslinking between polypeptides of the wool fabric under relatively mild processing conditions so as to enhance mechanical strength of the wool fabric whilst no significant effect of the original finish merino wool fabric and/or garment and fiber loss from fabric surface are observed, compared to conventional treatment methods on wool fabric. A corresponding coating formulation and method of fabricating the anti-pilling wool fabric are also provided. The present invention is applicable to finished wool fabric which fibers are already with colorant(s), and/or dye(s), and/or reactive dye(s).

Provided is a softening agent for textiles characterized by containing a compound (A) and a crosslinking agent (B). The compound (A) is a non-silicone compound having a polyoxyalkylene chain in the molecule, and has a functional group (R1) capable of producing an ether, an ester, or a nitrogen-containing compound upon reacting with the crosslinking agent (B).
