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 multi-chromatographic dyeing method for cellulose acetate with natural health care functions, including the following steps:

[0034] (1) Fiber modification pretreatment: the acetate fiber is modified pretreatment, the treatment conditions are: modification temperature 60℃, 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 end group polymer; wherein, the preparation method of the polyamino end group polymer: in an ice bath, two Ethylene triamine was added dropwise to the mixture of methyl acrylate and methanol, kept at 20-25°C (e.g. 20°C, 23°C, 25°C) and reacted for 4-6 hours (e.g. 4 hours, 5 hours, 6 hours), then The temperature is raised to 120-150°C under reduced pressure (for example, 120°C, 135°C, and 150°C), and the product is reacted for 2-4 hours (for example, 2h, 3h, 4h), and the methanol is evaporated. The molar ratio of divin...

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 method for dyeing acetate fiber with natural health care functions and a method for color mixing of multi-chromatographic fibers. It belongs to the fiber field. Background technique [0002] Acetate fiber is generally dyed with chemically synthesized dyes such as disperse dyes, especially the acetate fiber for cigarettes is white. Patent ZL200410065222.8 has reported a production method of colored cigarette acetate fiber tow, but it uses chemical synthesis Disperse dyes are not conducive to the health of smokers. At present, there is no report on the natural dyeing and multi-chromatographic fiber color mixing of acetate fiber with health care function, especially acetate fiber for cigarettes. Summary of the invention [0003] The purpose of the present invention is to provide a natural health function dyeing and fiber color mixing method of multicolor acetate fiber, which not only enriches the color of cigarette filters, but also...
