METHOD OF MODIFYING CELLULOSE DIACETATE FIBRES

摘要

FIELD: chemistry.SUBSTANCE: invention relates to the technology of producing modified polymer fibres, particularly modified and dyed cellulose acetate fibres. The composition for moulding fibres contains cellulose diacetate with acetyl number of 54.59%, a lycopene modifying additive and an organic solvent - mixture of acetone and water in volume ratio of 95:5.EFFECT: invention endows cellulose acetate fibres with a uniform, deep and physical-chemical resistant dye while providing high resistance to photo-oxidative degradation, simplifying the technique of dyeing and widening the range of dyes.2 tbl, 3 ex
