The present disclosure relates to a method for modifying polyester by a swelling agent combined with cutinase, belonging to the technical field of textile processing. According to the method, a phenol solution or an o-vanillin solution is used as the swelling agent to perform swelling treatment on the polyester, and combined with a Humicola insolens cutinase solution to perform hydrophilic modification on the polyester, which not only significantly improves the release amount of hydrolysates, but also reduces the fabric mass loss compared with the traditional chemical modification method.

The invention seeks protection for a novel method for the surface functionalization of solid materials with one or more active ingredients intended to confer specific properties thereon, such as anti-UV, fluorescence or coloring properties.

Antimicrobial and/or anti-odor textile coating composition that reduce and/or prevent bacterial growth and/or control odor(s) on a textile material treated for a prolonged time period including up to, for example, fifty wash cycles. The textile coating compositions may include benzoic acid and at least one of terephthalic acid, and/or a quat silane.

A method for reducing microbial growth and odor on a textile material are provided. The method comprises applying a composition to a textile material. The composition consists of a salt of benzoic acid; a non-benzoic acid consisting of sorbic acid, citric acid, lactic acid, acetic acid, L-glutamic acid, trisodium citrate, potassium sorbate, and combinations thereof. The composition has a weight ratio of salt of benzoic acid to non-benzoic acid ranging from 1:3 to 10:1 and the composition reduces microbial growth on the textile after laundering.

Modified regenerated collagen fibers which have improved water resistance and heat resistance problematic in regenerated collagen fibers, impart heat shape memory ability, are excellent in stretchability (tenacity) and the feel of the surfaces, and have no coloring. The modified regenerated collagen fibers contain a component (A), which is vinylbenzoic acid or a salt thereof, or a polymerized product containing the component (A) as a constituent monomer in the regenerated collagen fibers.

A fiber-treating agent which improves water resistance and heat resistance problematic in naturally derived fibers, imparts heat shape memory ability, improves stretchability (tenacity) and the feel of the surfaces, and causes no coloring of naturally derived fibers. The fiber-treating agent contains the following components (A) and (B): (A): a compound having a hydrogen bond term H in Hansen solubility parameter of 18.3 MPa.sup.1/2 or less, and having at least one of a carboxy group or a salt thereof, and no fused ring; and (B): water.
