The present invention relates to a method for modifying a textile yarn or fabric by immobilising a cyclodextrin derivative on said yarn or fabric, said process comprising a step (a) of contacting said textile yarn or fabric with said cyclodextrin derivative and with a bridging agent such as 1,2,3,4-butanetetracarboxylic acid, optionally in the presence of a catalyst such as cyanamide,

to obtain a textile yarn or fabric on which the cyclodextrin derivative of formula (I) is immobilised.

The present invention relates to single thread composite fibers comprising at least one binder and at least one active catalyst for the capture and degradation of chemical threats such as chemical warfare agents (CWA), biological warfare agents, and toxic industrial chemicals (TIC) and a method for producing the same. The invention fibers are applicable to the fields of protective garments, filtration materials, and decontamination materials.

Provided are MOF-fabric composites having a crystalline MOF adhered directly to fibers of the fabric and methods of making MOF-fabric composites. A solution is adsorbed onto a fabric. The solution can include a metal salt, a linker, and a solvent. The solution is adsorbed onto the fabric and the fabric suspended over a heated vapor. The vapor releases onto the fabric, causing the metal salt, the linker, and the solvent to diffuse out of the polymer fibers. The linker links metal from the metal salts to form crystals attached to the fabric, and the vapor aids crystallization.

Provided are a catalyst composition with improved processability and chemical warfare agent degradation ability, a film composite manufactured by casting the same, and a preparation method thereof. Specifically, provided are a catalyst composition including a copolymer of a first polymer and a second polymer; and a metal-organic framework (MOF), and a film composite including the same, wherein processability and catalytic activity are improved.
