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.

Fabrics that are exhibit water repellency, abrasion resistance, and optionally flame resistance are described herein. The fabrics include a plurality of fibers (such as flame resistant fibers) and a finish that imparts water repellency and abrasion resistance to the fibers. The fabrics are free or substantially free from alkylfluoropolymers. Also described herein are garments including the fabrics.

Nonwoven fiber webs are produced by spraying one or more aqueous binder formulations containing one or more polymers selected from the group of vinyl ester polymers and (meth)acrylic ester polymers, and in a separate step, spraying one or more aqueous silicone formulations containing one or more polysiloxanes, onto the surface of an airlaid nonwoven.

The present disclosure describes phosphonium-containing polyurethane compositions, coating compositions, and coated fabric media. In one example, a phosphonium-containing polyurethane composition can include an aqueous liquid vehicle and polyurethane particles. The polyurethane particles can include a polyurethane polymer devoid of end cap groups. The polyurethane polymer can include a polyurethane backbone having a polymerized diamine chain extender forming a portion of the backbone. The polyurethane polymer can also include side chain groups along the polyurethane backbone. The side chain groups can collectively include aliphatic phosphonium salts and polyalkylene oxide groups.

There is disclosed a method of coating textile fibers, the method comprising applying, on the external surface of textile fibers, a pre-treated oil-in-water emulsion comprising: (i) an aqueous phase containing water; and (ii) a pre-treated oil phase containing at least one reactive condensation-curable film-forming amino-silicone pre-polymer that, subsequent to condensation curing optionally in presence of additional reactants, forms an amino-silicone coat. The pre-treated reactive oil phase includes at least one pre-treated reactant or pre-treated pre-polymer. An aqueous dispersion containing particles of a hydrophilic polymeric material is then applied to the amino-silicone coat, so as to form a polymeric layer thereon. At least one of the oil-in-water emulsion forming a first coat and of the aqueous dispersion forming a second coat may further contain a plurality of sub-micronic pigment particles dispersed therein. Suitable compositions and kits including the same are also disclosed, as well as fibers coated thereby.

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.

A non-foamed aqueous composition can be applied to fabric substrates to provide non-foamed light-attenuating coatings in resulting coated fabric substrates that produce reduced glare from incident outside light. The non-foamed aqueous composition used to make these coated fabric substrates has a 5-50% solids and a zero shear viscosity of 100-1000 mPa-sec at 25° C. This composition has components i) through iv): i) porous particles at 0.1-20 weight %, and optionally an opacifying colorant; ii) a film-forming binder material comprising at least a chlorinated polymer at 4-20 weight %; iii) a white inorganic particulate filler material having a refraction index (RI) greater than 2 and a median particle size of less than 1 μm, at 5-16 weight %; and iv) a white low-density particulate hydrated alumina having a median particle size of less than or equal to 3 μm, at 2-16 weight %.
