DYEABLE AND FLAME-RETARDED THERMOPLASTIC POLYURETHANE FIBERS

摘要

The invention relates to a method of making a fabric comprising:
preparing a thermoplastic polyurethane composition, wherein said thermoplastic polyurethane composition comprises: a thermoplastic polyurethane comprising the reaction product of: (i) one or more polyols, (ii) one or more diisocyanates, (iii) one or more chain extenders, (iv) optionally one or more crosslinking agents, and (v) one or more functional modifiers, wherein each said functional modifier is a reaction product of an aminodiol and a Bronsted acid and wherein the functional modifier is incorporated into the backbone of the thermoplastic polyurethane; melt-spinning said thermoplastic polyurethane composition into a fiber; and processing the fiber into a fabric and a method of producing an article of clothing.
