Problems solved by technology

The dyeing method involved in the above-mentioned prior art belongs to intermittent dyeing, and only a certain amount of fibers can be dyed at a time, and continuous dyeing cannot be carried out.
At the same time, this dyeing method puts cotton loose fibers into the dyeing cage (or dyeing vat) during dyeing, and starts the circulating pump to circulate the dyeing liquid in the dyeing cage (or dyeing vat) for dyeing, but during the dyeing process, the dye is absorbed by the cotton Layers of fibers are hindered and cannot evenly enter the interior of the fibers, resulting in uneven dyeing, which will affect the final effect of cotton fiber dyeing

Embodiment 1

[0066] (1) Preparation of laps

[0067] Raw cotton fiber is prepared into cotton rolls with uniform thickness through picking cotton-matching cotton-cleaning-rolling.

[0068] (2) Dyeing

[0069] use figure 1 In the dyeing device shown, the cotton roll is placed on the unwinding unit 1, and is unwound into a cotton layer (thickness is 20mm, 430g / m 2 ), the cotton layer is conveyed horizontally on the endless mesh belt unit 2. Among them, the closed-loop guide belt is a 60-mesh polyester screen. The circulating mesh belt unit 2 is in contact with the rollers for cyclic operation, and at the same time, the mesh belt deviation correction device, mesh belt tensioning device and guide roller follow the upper and lower circulating mesh belts for synchronous operation.

[0070] Carry out spray dyeing during conveying process, newly equipped dye liquor spray equipment 31 sprays newly prepared dye liquor, the spray speed is 800g / min, reuse dye liquor spray equipment 32 sprays back ...

Embodiment 2

[0084] (1) Preparation of Articles and Volumes

[0085] The raw cotton fibers are blown-carded-pre-drawn-slivers and rolled to prepare slivers with uniform thickness and rolled.

[0086] (2) Dyeing

[0087] use figure 1 In the dyeing device shown, the cotton sliver is rolled up on the unwinding unit 1, and the cotton layer (thickness 8mm, 180g / m2) is formed through the unwinding unit. 2 ), the cotton layer is conveyed horizontally on the endless mesh belt unit 2. Among them, the closed-loop guide belt is 80 mesh nylon wire mesh. The circulating mesh belt unit 2 is in contact with the rollers for cyclic operation, and at the same time, the mesh belt deviation correction device, mesh belt tensioning device and guide roller follow the upper and lower circulating mesh belts for synchronous operation.

[0088] Spray dyeing during the conveying process, the newly equipped dye liquor spraying equipment 31 sprays the newly prepared dye liquor, the spraying speed is 600g / min, and t...

Abstract

The invention provides a dyeing device for a cotton fiber. The dyeing device comprises an unwinding unit, a circulating mesh belt unit, a spraying unit, a roll compacting unit and a feeding unit; theroll compacting unit comprises a plurality of padder equipment arranged in sequence; the circulating mesh belt unit comprises an upper circulating mesh belt and a lower circulating mesh belt which respectively form independent closed loops; the lower circulating mesh belt is connected with the unwinding unit, and the upper circulating mesh belt is connected with the first padder equipment of the roll compacting unit; and the spraying unit is located in front of the first padder equipment of the roll compacting unit and is located above the lower circulating mesh belt. The invention provides adyeing method of the cotton fiber, and the dyeing method comprises the steps: preparing a cotton fiber layer from raw cotton fibers; horizontally conveying the cotton fiber layer by a guide belt, spraying a dye liquor firstly, and then, carrying out roll compacting many times in the conveying process to obtain a dyed cotton fiber layer. If the dyeing device provided by the application is adopted for dyeing the cotton fiber, the cotton fiber can be uniformly dyed, the usage amount of the dye liquor is small, the dyeing effect is good, and the work efficiency is high.

Description

technical field [0001] The invention belongs to the technical field of textile dyeing, and in particular relates to a cotton fiber dyeing device and a dyeing method thereof, in particular to a continuous dyeing device for cake-shaped cotton fibers and a low liquor ratio dyeing method for cotton fibers. Background technique [0002] Cotton fiber is an important raw material for the textile industry. It is widely used because of its good properties such as strong hygroscopicity, good softness, good air permeability and wear resistance. With the continuous improvement of people's living standards, the demand for different fabrics is gradually increasing, and some of the fabrics are woven from cotton fiber yarns of different colors. The cotton fiber yarns of different colors need to be dyed by some special equipment. Traditional cotton fiber dyeing is divided into cheese dyeing and loose fiber dyeing. [0003] In the prior art, because cotton fiber belongs to short fiber, conti...
