A method of producing a laminated body, the method including a coagulant solution deposition step of depositing a coagulant solution on a fiber substrate, and a coagulation step of forming a polymer layer on the fiber substrate by bringing a polymer latex into contact with the fiber substrate having the coagulant solution deposited thereon to cause a polymer to coagulate. As the coagulant solution, a solution obtained by dissolving or dispersing 0.2 to 7.0% by weight of a metal salt as a coagulant and 0.1 to 7.0% by weight of an organic acid in a solvent is used. In the method of producing a laminated body, the metal salt is a polyvalent metal salt. In the method of producing a laminated body, the organic acid is an organic acid having at least one group selected from a carboxyl group, a sulfo group, a hydroxy group, and a thiol group.

A laminated body formed by laminating a fiber substrate composed of a plurality of fibers and a polymer layer formed from a polymer latex. The polymer layer covers the fiber substrate in a state in which a portion of the polymer layer has permeated among the fibers. A ratio (t.sub.1/d) of a thickness t.sub.1 of the portion of the polymer layer that has permeated among the fibers (from a top surface of the fiber substrate) to a substrate layer average thickness d is 0.1 to 0.95. A thickness t.sub.2 of the portion of the polymer layer covering the top surface of the fiber substrate (from the top surface of the fiber substrate) is 80 μm or more.

The disclosure provides a fibrous material comprising a plurality of fibers, the fibers being natural or synthetic cellulosic fibers or natural or synthetic protein fibers, and wherein the fibers are treated with a cationic compound. The disclosure also provides a method for imparting improved compatibility with quaternary ammonium compounds to a fibrous material, including: providing a fibrous material comprising a plurality of fibers, the fibers being natural or synthetic cellulosic fibers or natural or synthetic protein fibers; optionally, pre-treating the fibrous material with a base; treating the fibrous material with at least one cationic compound to impart improved compatibility with quaternary ammonium compounds; and optionally, further treating the treated fibrous material with a polymer or resin.

The present invention aims to provide a technique for preparing a complex fiber covered by silica and/or alumina at a high coverage ratio. According to the present invention, complex fibers comprising silica and/or alumina deposited on the surface of a fiber at a high coverage ratio can be prepared by synthesizing silica and/or alumina on the fiber while maintaining the pH of the reaction solution containing the fiber at 4.6 or less.

The present invention provides a fiber modifier composed of an internal olefin sulfonate having 17 or more and 24 or less carbons.

A method for manufacturing gloves includes adding a thickening agent (B) having an oxyethylene group content of 210.sup.2 mol/g or less to an aqueous urethane resin composition containing an aqueous urethane resin (A) having an acid value of 0.01 mgKOH/g or higher in a range of 0.01 to 30 parts by mass relative to 100 parts by mass of the aqueous urethane resin (A) to obtain a thickened liquid; and (i) immersing fiber-knitted gloves in the thickened liquid and subsequently performing coagulation in a coagulation bath (C) containing a metal salt (c-1) or (ii) immersing fiber-knitted gloves previously immersed in a coagulation bath (C) containing a metal salt (c-1) in the thickened liquid to perform coagulation. As the thickening agent (B), a cellulose thickening agent, an acryl thickening agent, or a urethane thickening agent can be used. Furthermore, as the metal salt (c-1), calcium nitrate can used.
