Problems solved by technology

[0002] The dyeing of acetate fibers generally adopts chemically synthesized dyes such as disperse dyes, especially the acetate fibers for cigarettes are all white. Patent ZL200410065222.8 once reported a production method of colored acetate fiber tows for cigarettes, but it uses chemically synthesized dyes. Disperse dyes, not good for the health of smokers
At present, there is no report on the natural dyeing and color mixing of acetate fibers with health care functions, especially acetate fibers for cigarettes

Embodiment Construction

[0033] A kind of natural health-care function multi-chromatographic dyeing method of acetate fiber, comprises the following steps:

[0034] (1) Fiber modification pretreatment: Modification pretreatment of acetate fiber, the treatment conditions are: modification temperature 60°C, time 75min, polyamino oligomer modifier concentration 2g / L, caustic soda concentration 1.5g / L ; The polyamino oligomer modifier is octadecyl dimethyl benzyl ammonium chloride or polyamino terminal polymer; wherein, the preparation method of polyamino terminal polymer: in ice bath, two Ethylene triamine is added dropwise to the mixture of methyl acrylate and methanol, and kept at 20-25°C (for example, 20°C, 23°C, 25°C) for 4-6 hours (for example, 4 hours, 5 hours, 6 hours), and then Heat up to 120-150°C under reduced pressure (example 120°C, 135°C, 150°C) and react for 2-4 hours (example 2h, 3h, 4h) to obtain the product, and distill off the methanol. The molar ratio of divinyltriamine to methyl acry...

Abstract

The invention discloses a natural healthcare multicolor dyeing method of acetate fibers. The method comprises the following steps: carrying out modification pretreatment of fibers, dyeing the obtained acetate fibers subject to the modification pretreatment by a dyeing liquor extracted from a natural plant or a Chinese herbal medicine, and carrying out transglutaminase treatment of the obtained dyed acetate fibers. The method has the advantages of uniform dyeing, bright color, high crock, water and saliva fastnesses (respectively reaching 4 grade), and small influences on the performances of the fibers (a blue color system fiber strength retention of above 80% and other strength retentions of above 90%). The plant or the Chinese herbal medicine used in the invention has certain drug effects, so the dyed acetate fibers for cigarette have healthcare functions. The method enriches the color of cigarette filters, and protects the health of smokers.

Description

technical field [0001] The invention relates to a natural health-care function dyeing method of acetate fiber and a multi-chromatographic fiber color mixing method. It belongs to the fiber field. Background technique [0002] The dyeing of acetate fibers generally adopts chemically synthesized dyes such as disperse dyes, especially the acetate fibers for cigarettes are all white. Patent ZL200410065222.8 once reported a production method of colored acetate fiber tows for cigarettes, but it uses chemically synthesized dyes. Disperse dyes are not conducive to the health of smokers. At present, there is no report on the natural dyeing and color mixing of acetate fibers with health care functions, especially the acetate fibers for cigarettes. Contents of the invention [0003] The purpose of the present invention is to provide the natural health-care function dyeing and fiber color mixing method of multi-color acetate fiber, which not only enriches the color of cigarette filt...
