Problems solved by technology

However, the carriers commonly used in the early days, such as: wintergreen oil, methylnaphthalene, phenylphenol, chlorobenzene, etc., are highly toxic, smelly, poor in biodegradability, and difficult to unload, which makes dyed fabrics have a certain odor. are greatly restricted, so new environmental protection carriers need to be developed urgently

Abstract

The invention relates to a method for preparing a terylene environmental protection type dyeing carrier, which comprises the following steps: (1) alkylamine, dimethylformamide, phthalic anhydride and triethylamine are added into a three-neck flask with the volume of 500mL under the condition of ice bath and are subject to thermal insulation reaction for one hour; then the temperature is increased to 120 DEG C to perform a reflux reaction for four hours; the mixture is dumped into ice water after the reaction is finished; and white crystals are precipitated; (2) according to the mass proportion of 4 to 1, a carrier precursor is added into an emulsifying agent, heated and stirred; and (3) the process formulation is a dispersion dye, 1 to 3 percent owf of carrier, and 0.3g to 0.5g.L<-1> of glacial acetic acid; the bath ratio is 1 to 20; the dyeing temperature is between 85 and 100 DEG C; the thermal insulation time is between 60 and 100 minutes; and the dyeing carrier is washed and aired. The method is suitable for terylene boiling dyeing processes of dyeing and finishing plants, can reduce production cost, and shorten dyeing period. The textile after the dyeing has bright color, pure chromatic light, high brightness, no toxicity, no smell, and low COD value, so the dyeing carrier is an environment-frinedly green auxiliary.

Description

technical field [0001] The invention belongs to the field of preparation of polyester dyeing carriers, in particular to a preparation method of polyester environment-friendly dyeing carriers. Background technique [0002] Polyester fiber has the advantages of high crystallinity, compact structure, good elasticity and high wear resistance, but its structure lacks active groups that can combine with dyes, making it difficult to dye. Usually, high temperature and high pressure methods, hot melt methods, organic It can be dyed by methods such as solvent method or carrier method. In recent years, with the continuous emergence of new functional fibers, people pursue the individuation, diversification and functionalization of clothing. Many multi-fiber composite fabrics are more widely used, such as wool, silk, acetate fiber, spandex and polyester fiber blended fabrics. Much favored by consumers. However, wool, silk, acetate fiber, spandex and other fibers are not resistant to hi...
