A composition for treating textile materials includes water, polyethylene, surfactant, preservative, and a mixture comprising sugar alcohol, hydrolyzed animal protein, and sarcosine compound. The composition can further include a fragrance. A textile material treated with the compositions described above can be a material selected from leather, nylon, or a mixture thereof. A method of preparing a composition for treating a textile material is also disclosed.

A heat insulation material is provided that is produced by drying a fibrous matrix impregnated with a solution of pseudo-peptides of formula (I), wherein: R is a side-chain of a natural or synthetic amino acid, R1 is either a linear or branched (C.sub.1-C.sub.3)alkyl group, or a linear or branched (C.sub.1-C.sub.3)alcoxy group, or an aryl group, or an aryl(C.sub.1-C.sub.3)alkyl group, or an aryloxy group, or a saturated or unsaturated heterocycle, n=1 or 2, and A is an aromatic or heteroaromatic group with at least one cycle.

Compositions and methods are described that provide cellulosic and non-cellulosic fabrics with durable antimicrobial properties. Application of a coating that includes polyhexamethylene biguanide, polyethylene glycol, and a binder to a fabric followed by drying and curing was found to provide antimicrobial properties that are retained through over 100 washings under aggressive hospital washing conditions. In addition, tactile properties and tear resistance of the treated fabrics are maintained or improved.

Polyester-free cotton is obtained from a fabric and/or fibers containing polyester and cotton by reacting the fabric and/or fibers with an amine organocatalyst and/or carboxylic acid salt of same and an alcohol solvent. The reaction, which may be run in batches or as a continuous flow process, recovers (i) polyester-free cotton as a solid inert by-product of the reaction, (ii) the amine organocatalyst and/or carboxylic acid salt of same for reuse, (iii) a polyester monomer product, and (iv) unreacted alcohol. The reaction works on any polyester-cotton fabric and/or fibers, including those that have at least one additional material, such as polyethers polyolefins, polyurethanes, nylon, rayon, acetate, viscose, modal, acrylic, wool, and combinations thereof.

Described are polymer particles or polymer fibers covalently bonded to N-chloroamines, N,N-dichloroamines, N-chloro sulfonamides or N,N-dichloro sulfonamides, for removing volatile organic compounds (VOCs) from a space above a wound. The removal of said VOCs is believed to be primarily or predominantly by chemical reaction of the VOCs with the N-chloro or the N,N dichloro group as covalently attached to the polymer. In particular, the functionalized polymer particles or polymer fibers are part of a wound dressing and have the functionality to control, in particular reduce, odor emanating from wounds, without interacting with the wound. The described dressings can be advantageously used, in particular, in the treatment of chronic wounds or infected wounds.

A composite fiber includes a core comprising a MXene polymer fiber with MXene distributed as stacked nanosheets within a first polymer, a first coating layer of benzoic acid-based organic molecules on the MXene polymer fiber, a second polymer in fiber form on the first coating layer, and a second coating layer of a thermoplastic polymer with a thermal strain of about 80 C. or higher. The method for manufacturing the composite fiber involves mixing MXene and a first polymer, depositing a first coating layer, plying and twisting with a second polymer, and applying a second coating layer. The first polymer may include polyacrylonitrile (PAN), and the second polymer may include materials such as nylon or polyethylene terephthalate (PET). The process includes steps such as wet spinning and surface treatment at high temperatures.
