Staining method of tip brush silk

Abstract

The invention discloses a dyeing method for neb brushing wire, comprising following procedures that stocks are mixed equally into color paste, whose PH value is among 1-9; the color paste is coated on the neb end of yarn cake or the neb end is used to fetch color paste; then it is sent into the coloring equipment and it is colored for 1-60 minutes in maintaining temperature of 100-200deg.C; and then the yarn cake is taken out from coloring equipment, residual color slurry is washed by water, it is dried or baked, it is packaged into finished product. Stocks are matched with following components of 5-25 share of disperse dyes by wt, 15-35 share of warm water with 50-60deg.C by wt and 40-80 share of original paste by wt. The invention adopts color slurry to dye neb brushing wire, conquers capillarity phenomena of dye, solves problems of uneven color, fixed length and location dyeing, at the same time solves color difference problem and advances the grade of production.

Description

Technical field: [0001] The invention relates to a dyeing method of brush filaments, in particular to a dyeing method of pointed brush filaments. Background technique: [0002] At present, whether it is a flat brush or a pointed brush, the dyeing is to immerse the part of the brush to be dyed in the dye solution, and the color is formed under certain temperature and time conditions. During the dyeing process, the brush filament has capillary Phenomenon, so that the parts not immersed in the dyeing solution are also colored to varying degrees, and there is also uneven coloring in the immersed parts. At the same time, the color difference between each batch is serious, resulting in lower grades of dyed products. Cannot be used to make high-end toothbrushes. Invention content: [0003] The technical problem to be solved by the present invention is to provide a method for dyeing brush filaments, which is uniform in dyeing, has no color difference, and can realize fixed-length...
