Embodiment

[0011] A method for producing acetate fiber tow for colored cigarettes, comprising making diacetate sheets into a slurry and spinning, and when the diacetate sheets are made into a slurry, the concentration of the diacetate sheets is 15% to 35% (can be 15%, 25%, 35%), and add 0.1~1% (eg 0.1%, 0.5%, 1%) color dyes by weight in the slurry. The color dye is added under a pressure of 0.5-2.5MPa and a slurry concentration of 35-65°C (for example, 35°C, 45°C, 55°C, 65°C). The color dyes are R / blue KF dyes produced by Shanghai Yuanguang Company or Huadie brand disperse dyes.

Abstract

The invention discloses a production method of acetate fiber tow for colored cigarettes, which comprises making diacetate sheets into a slurry and spinning, and when the diacetate sheets are made into a slurry, the concentration of the diacetate sheets is 15 to 100%. 35%, and 0.1 to 1% by weight of color dyes are added to the slurry. The dyeing process of the present invention is simple and reliable, and has no adverse effect on the subsequent processing and molding of acetate tow. The color additives are evenly distributed in the acetate tow for cigarettes. The colored acetate tow is bright in color and does not decolorize after soaking in water for 48 hours. .

Description

Technical field: [0001] The invention relates to a production method of cellulose acetate tow for cigarettes. Background technique: [0002] At present, the cellulose acetate tow for cigarettes on the market is white, and there is no report on the production process of colored cellulose acetate tow for cigarettes. Invention content: [0003] The object of the invention is to provide a production method of acetate fiber tow for colored cigarettes with simple process and good effect. [0004] Technical solution of the present invention is: [0005] A method for producing acetate fiber tow for colored cigarettes, comprising making diacetate sheet into slurry and spinning, the difference from the prior art is: when diacetate sheet is made into slurry, diacetate The concentration of the vinegar flakes is 15-35%, and 0.1-1% by weight of color dye is added to the slurry. [0006] The color dye is added at a pressure of 0.5-2.5 MPa and a slurry concentration of 35-65°C. [000...
