Preparation and application of durable non-formaldehyde flame retardants for cotton fabric
摘要
Abstract
A phosphate ester non-formaldehyde flame retardant for cotton fabric was synthesized by di⁃ethyl phosphite, N,N′-methylene-bis(acrylamide) and epichlorohydrin, and its structure was characterized by IR, 1H-NMR, 31P-NMR, ESI+-MS and ESI--MS. The flame retardant was applied in flame resistant finishing of cotton fabric. The flame retardant finishing process was optimized by exploring the amount of flame retardant and cross-linker, the curing temperature and pH. The TGA test showed that the pyrolysis stage of finished cot⁃ton fabrics stil existed, and pyrolysis temperature of each stage decreased greatly compared with the original fabric′s, and the amount of residue increased by 25.7%. The flame retardance of cotton fabric was effectively improved. The SEM images indicated that the finished cotton fabric stil kept the original fibrous shape and its carbon layer didn′t col apse after burning. After 10 times of washing, the flame retardant cotton fabric was stil up to GB B2 level indicating good washing fastness.关键词
