Disclosed is an elastic fiber treatment agent that contains a smoothing agent and an alkyl phosphate ester compound. The alkyl phosphate ester compound contains specific phosphate ester Q1 and at least one or more selected from specific phosphate esters Q2 and Q3. In a P nucleus NMR measurement of the alkyl phosphate ester compound upon an alkali over-neutralization pretreatment, a P nucleus NMR integral ratio attributed to the phosphate ester Q1 is 15% to 60% if the sum of P nucleus NMR integral ratios attributed to the phosphate esters Q1 to Q3 and phosphoric acid and its salt is taken as 100%.

The present invention provides a method of treating a substrate in order to improve its properties of absorbing malodorous molecules, in particular associated with sweat, the method comprising the following steps: i) preparing an acid aqueous composition comprising at least one organosilane A having at least one hydrolyzable alcoxy group, and at least one main polycarboxylic acid B comprising at least four COOH carboxyl groups or its corresponding anhydride comprising at least four COOCO groups; the weight ratio of said at least one organosilane A over the weight of said at least one main polycarboxylic acid B, lying in the range 0.8 to 1.2; ii) applying said composition on said substrate; and iii) heating said substrate comprising said composition to a temperature higher than or equal to 120 C., preferably higher than or equal to 130 C., in order to polymerize said organosilane A with at least the main polycarboxylic acid B or its corresponding anhydride.

Methods of treating fibers comprising a polymer including at least one of a vinyl acetate moiety or a vinyl alcohol moiety, and resulting fibers or the products comprising the resulting fibers are disclosed. In an example embodiment, a fiber having a surface region and an interior region, includes a polymer comprising at least one of a vinyl acetate moiety or a vinyl alcohol moiety chemically modified with a modification agent. The fiber has a transverse cross-section including the interior region comprising the polymer having a first degree of modification and the surface region comprising the polymer having a second degree of modification greater than the first degree of modification.

An allergen reducing composition capable of reducing allergens such as mites and cedar pollen and causes less coloring of an allergen reduction target; a spray agent using the allergen reducing composition; a surface treatment agent using the allergen reducing composition; an allergen reducing method; an allergen reducing textile structure; and an allergen reducing architectural interior material. The allergen reducing composition contains: (A) one or more compounds selected from zinc salts and copper salts; and (B) one or more compounds selected from rare earth salts. The spray agent or the surface treatment agent contains the allergen reducing composition and water or a water-soluble solvent. An allergen reducing method involves using the above-mentioned allergen reducing composition in an environment where allergens are present. The textile structure is a textile structure processed by the allergen reducing composition. The architectural interior material is one processed by the allergen reducing composition.
