A fiber composite includes a cellulose fiber and a metal, in which the cellulose fiber contains a cellulose acylate, at least a part of a surface of the cellulose fiber carries at least a part of the metal, a degree of crystallinity of the cellulose fiber is from 0% to 50%, an average fiber diameter of the cellulose fiber is from 1 nm to 1m and an average fiber length of the cellulose fiber is from 1 mm to 1 m.

The invention relates to a composition for forming artificial leather said composition comprises at least one polymer and plant powder from plant remains having cellulose, having a grain size of 1 ?m to 1 mm and a moisture content of less than 20 weight percent.

Disclosed are fibers which contain identification fibers. The identification fibers can comprise one or more chemical markers, or taggants, which may vary among the fibers or be incorporated throughout all of the fibers. The disclosure also relates to the method for making and characterizing the fibers. Characterization of the fibers can include identifying chemical markers and correlating the chemical markers and a taggant chemical marker amounts of at least one of the chemical markers to manufacturer-specific taggants to determine supply chain information. The supply chain information can be used to track the fibers from manufacturing through intermediaries, conversion to final product, and/or the consumer.

A method of modifying one or more cellulose fibres and/or cellulosic fabric, wherein the method comprises: (a) providing an aqueous solution comprising at least one hydrocarbon acid and at least one acid catalyst and/or at least one emulsifier; (b) treating one or more cellulose fibres and/or cellulosic fabric with the aqueous solution provided in step (a) to couple the one or more cellulose fibers and/or cellulosic fabric with the at least one hydrocarbon acid.

A hydrophilized cellulose acetate tow band according to the present invention includes a crimped cellulose acetate tow band, and a hydrophilizing component having an HLB value of 16 or more. The cellulose acetate tow band includes a cellulose acetate having a degree of substitution of 2.0 to 2.6. The cellulose acetate tow band has a total denier of 10000 to 40000 and is crimped in a number of crimps of 30 to 60 per inch. The hydrophilizing component is impregnated on the cellulose acetate tow band in an amount of 0.2 to 2 weight percent relative to the cellulose acetate tow band. The hydrophilized cellulose acetate tow band may further include a textile oil, where the textile oil is impregnated on the crimped cellulose acetate tow band in an amount of 0.2 to 2 weight percent relative to the cellulose acetate tow band, in addition to the hydrophilizing component having an HLB value of 16 or more.

A stainable decorative sheet having good adhesion between a paper base material and a nonwoven fabric with a surface excellent in tactile sensation and stainability, excellent transparency, and a method for coloring the stainable decorative sheet. The stainable decorative sheet includes a paper base material, an adhesive layer, a nonwoven fabric layer, and a transparency improving layer in a predetermined structure, wherein the nonwoven fabric layer partially has a filling part A and a filling part B in a part of voids among fibers of the nonwoven fabric layer.
