A method for fiber modification provided in the present disclosure comprises the following steps: reacting fibers with a hypochlorous acid oxidant for development of antioxidant fibers, separating the antioxidant fibers from the hypochlorous acid oxidant and drying the antioxidant fibers to develop modified fibers which feature better oxidation resistance.

formaldehyde-based polymer composite is coated on a surface of the biodegradable polymer fabric, and is embedded in meshes of the biodegradable polymer fabric. There is intermolecular hydrogen-bond interaction between the biodegradable urea-formaldehyde-based polymer composite and the biodegradable polymer fabric.

The present disclosure is directed to a kind of functional fabric coating that may be applied (or coated) on a synthetic fabric that can effectively alter the opacity (i.e., transparency, sheer proof, light shielding) and hydrophilicity (i.e., wicking, moisture management) of the finished fabric, without significantly affecting the synthetic fabric's physiochemical properties.

This invention provides a composition and aqueous dispersion comprising magnesium oxide, as a sole active agent or in combination with ammonium phosphate/ammonium polyphosphate for imparting anti-bacterial and/or anti-viral properties to textile products. The present invention further provides methods for preparing such compositions and aqueous dispersions and methods of using the same for textile finishing.

A method is for preparing acrylic acid from β-propiolactone and for using β-propiolactone. The process is based on a specific reactivity of β-propiolactone whereby acrylic acid is formed under operating conditions that are mild, especially in terms of temperature.

A method of spreading fiber tows includes assembling a fibrous composite from a plurality of tows, applying an aqueous solution to the fibrous composite, freezing the fibrous composite after applying the aqueous solution, freeze drying the fibrous composite to remove water from the fibrous composite, and heating the fibrous composite after freeze drying to remove a cryoprotectant from the fibrous composite. The aqueous solution comprises water and the cryoprotectant and freezing the fibrous composite spreads filaments within the plurality of fiber tows.

Embodiments of the present disclosure generally relate to coated substrates having, e.g., anti-viral properties, to articles including the coated substrates, and to processes for making such coated substrates and articles. In an embodiment, a mask for preventing infection by a virus is provided. The mask includes a coated substrate having a breathing resistance (95 L/min, EN 149:2001) of about 6 mbar or less and a water droplet absorption time of less than about 5 seconds. The coated substrate includes a non-woven fabric having a weight of about 120 g/m.sup.2 or less according to ASTM D3776, and mineral oxide particles, iron oxide particles, or both, coupled to at least a portion of the non-woven fabric.

The present disclosure provides fabrics comprising graphene and/or its derivative(s), wherein said graphene comprising fabrics are characterized by at least three features selected from anti-microbial, antistatic, wicking, thermal cooling, anti-odour and ultraviolet protection. Said graphene comprising fabrics of the present disclosure show several further beneficial properties including but not limited to good/excellent washing fastness, rubbing fastness, perspiration fastness, sublimation fastness and light fastness.

A method for providing a bio-active layer on a surface, includes the steps of: a) ionizing a plasma gas at low temperature of 150° C. or lower, and at about atmospheric pressure, thereby creating a plasma; b) introducing a precursor into said plasma; c) exposing the surface to said plasma comprising said precursor, thereby forming a coating onto the surface. The precursors include a biological pathogen transfer inhibiting compound.

The present invention relates to a method for preparing a textile finishing agent based on an eco-friendly, renewable, and biodegradable biopolymer, and, specifically, to a method for preparing a textile finishing agent, comprising the steps of: forming, at room temperature, a solution comprising an organic acid and the balance of a solvent; stirring chitosan and a base solvent in the solution; and preparing a solution in which a mineral material is dissolved.
