Description

A kind of superfine fiber continuous dyeing method and dyeing machine

technical field

The invention relates to a continuous dyeing method and a dyeing machine for superfine fibers, belonging to the technical field of fabric dyeing.

Background technique

Microfiber is composed of fiber and resin. The fineness of the fiber is only 0.0001-0.001 denier. The gaps between the fibers are filled with foamed resin. characteristic. Existing microfiber dyeing technologies all belong to the exhaust dyeing method. Exhaust dyeing is to immerse ultrafine fibers in dyes, and through dyeing vat circulation or ultrafiber movement, the ultrafine fibers are repeatedly dipped in the dyeing solution to make them constantly move relative to each other. The method of gradually dyeing superfine fibers with dyes is shown in Figure 1; during the dip-dyeing process of superfine fiber cloth, the dye molecules are first on the outside of the microfiber cloth, and after a long time of soaking, the dye molecules can penetrate into the superfine fibers As for the inside of the cloth, dyeing is finished.

Due to the high density and thicker thickness of superfine fibers, the existing technology is to prolong the time of superfine fibers in the dyeing vat to achieve the purpose of uniform dyeing and core penetration, and the ultrafine fibers are dyed by exhaust dyeing. Due to the heavy weight of microfiber cloth, the bath ratio is large, which wastes dyes and energy, increases the burden of wastewater treatment, and requires manual operation for microfiber to enter and exit the dyeing machine, which is labor-intensive and low-yield.

Existing exhaust dyeing methods use intermittent cylinder-type dyeing equipment such as general jiggers, rope dyeing machines, and overflow dyeing machines for superfine fiber dyeing. These dyeing equipment have complex structures, and the dyeing process consumes a lot of energy and labor intensity. , low output, difficult color matching, large color difference between each cylinder, long dyeing time, and great damage to the physical properties of microfibers.
