It is an object of the present invention to provide ultrafine cellulose fibers capable of exhibiting favorable dispersibility even in an organic solvent. The present invention relates to cellulose fibers having a fiber width of 1000 nm or less and having phosphoric acid groups or phosphoric acid group-derived substituents, wherein the content of the phosphoric acid groups or phosphoric acid group-derived substituents is 0.5 mmol/g or more, and the supernatant yield measured by an measurement method (a) is 70% or less.

A fabric delivers active ingredients to a surface when the fabric includes a moist-vapor porous combination of fabric materials, and the fabric comprises at least 0.5% by total weight of at least one layer of the fabric of a superabsorbent polymer fiber. The superabsorbent polymer fiber contains an absorbed aqueous reservoir of an aqueous solution carrying the active ingredients. The superabsorbent fiber has a coating on its surface of an aqueous penetrable layer through which a liquid in the absorbed aqueous reservoir can migrate or flow, carrying the active ingredients onto an exposed surface of the superabsorbent polymer fiber, so that the active ingredients on the surface of the superabsorbent polymer can react or interact with an environment in contact with the active ingredients on the superabsorbent polymer fiber surface.

A cleaning system for cleaning high performance textiles, sports gear, and/or other laundry, which includes a washing agent and a protective agent. The washing agent is configured to remove unwanted matter from the high performance textiles, sports gear, and/or other laundry. The protective agent is configured to create a bonded barrier comprising organosilane antimicrobial(s) on the high performance textiles, sports gear, and/or other laundry for protection against odors from bacteria, mold and mildew and/or the like. The washing agent and the protective agent are configured to be used in a two-step water-based treatment process in which the washing agent is provided in a given first step of the treatment process and the protective agent is provided in a given subsequent second step of the treatment process.

A fiber structure contains polyester fibers 1 and a hydrophilic polyester resin treatment agent, wherein part 2a of a molecule 2 of the hydrophilic polyester resin treatment agent is absorbed in at least part of the polyester fibers 1, and the remainder 2b of the molecule extends along the surface of the polyester fibers 1 to hydrophilize the surface. The fiber structure has the properties below: (1) antifouling properties of grade 4 or higher according to the gray scale assessment determined by applying 200 g of muddy water, which is a mixture of normal staining soil and sand and distilled water at a ratio of 1:1, to the fiber structure, followed by standing for 24 hours, washing, and drying; (2) water absorbability of 10 seconds or less according to the falling-drop method; and (3) diffusivity of 55 minutes or less according to the diffusible residual water content test (dropping 0.6 mL of water). Thus, the present invention provides a fiber structure not involving curing to keep a good texture while having high antifouling properties, water absorbability, diffusivity, etc.
