[0028] In this embodiment, a circulation component is arranged below the lower guide belt 6, and the circulation component includes a liquid sump 2, a return pipe 11, a liquid replenishment pump 14 and a heat exchanger 15, and the return pipe 11 can be provided with a return pipe-11a, a return flow Pipe two 11b, return pipe three 11c, return pipe four 11d and return pipe five 11e, return pipe one 11a, return pipe two 11b, return pipe three 11c, return pipe four 11d and return pipe five 11e are connected to the sump 2 at one end , the other end is sequentially connected with the first sprinkler 9a, the second sprinkler 9b, the third sprinkler 9c, the fourth sprinkler 9d and the fifth sprinkler 9e, and the rehydration pump 14 and the heat exchanger 15 are installed on the return pipe 11 , the replenishment pump 14 pumps the liquid in the liquid collection tank 2 back into the return pipe 11, and the heat exchanger 15 adjusts the temperature of the liquid recycled in the return pi...

Embodiment 3

[0030] Example 3: Conventional Loose Fiber Dyeing

[0031] Dyeing vats are used to dye loose fibers. The dyeing process and process conditions are as follows:

[0032] (1) Pre-treatment: pre-treat the loose fibers under high-temperature alkaline conditions, so that the cotton has better water absorption, which is conducive to the adsorption and diffusion of dyes during dyeing.

[0033] (2) Bleaching and brightening: The pretreated loose fibers are subjected to oxygen bleaching treatment, in which alkali agents and hydrogen peroxide stabilizers need to be added to the oxygen bleaching, and pickling is carried out.

[0034] (3) Dyeing: add dyes and auxiliaries to the bathtub, among which, auxiliaries, salt, sodium sulfate, etc. are needed in the dye, the bath ratio is 1: (10-20), the loose fiber after bleaching and whitening Placed in the dyeing vat, the dyeing solution is transported by the main pump, from the inner layer of the dyeing vat to the outer layer to penetrate and c...

Abstract

The invention relates to a spray-rolling type loose fiber dyeing machine, and belongs to the technical field of loose fiber dyeing. The spray-rolling type loose fiber dyeing machine comprises a transmission component and a spray component. The transmission component comprises a pair of upper drive rollers and a pair of lower drive rollers. The upper drive rollers and the lower drive rollers are sleeved with an upper guide belt and a lower guide belt respectively to be used in a cooperative mode. The upper guide belt is provided with a first leak hole, the upper guide belt and the lower guide belt operate synchronously, a plurality of upper rollers are arranged in an upper guide belt loop, and a plurality of lower rollers matched with the upper rollers to be used are arranged in a lower guide belt loop. The upper guide belt and the lower guide belt are matched with the upper rollers and the lower rollers to achieve synchronous clamping transportation of the loose fibers. The spray component comprises a dyeing liquid pipe and sprayer heads. One end of the dyeing liquid pipe is communicated with dyeing liquid, the other end of the dyeing liquid pipe is connected with the sprayer heads, the sprayer heads are located above the upper guide belt between adjacent upper rollers, and the dyeing liquid in the dyeing liquid pipe is sprayed downwards onto the loose fibers through the sprayer heads. By means of the spray-rolling type loose fiber dyeing machine, continuous production can be carried out, cost can be lowered to 1/3-1/5 of that in the prior art.

Description

technical field [0001] The invention relates to a padding type loose fiber dyeing machine, which belongs to the technical field of loose fiber dyeing. Background technique [0002] Conventional fiber dyeing is carried out in the dyeing vat, and the loose fiber cake is hung into the dyeing vat for dip dyeing. The defects of this method are: 1. During the dyeing process, it is necessary to add auxiliary dyeing accelerators and dyeing enhancers to Ensure the dyeing rate; 2. During the dyeing process, refining, bleaching, washing, softening and other processes are required, the processing process is long and the operation is cumbersome; 3. The dyeing process is carried out by dipping, the dyeing cycle is long, and the dyeing uniformity Not good, the dyeing vat needs to be equipped with main pumps, auxiliary pumps and other devices, which consume a lot of power and energy. Contents of the invention [0003] In order to overcome the defects of long dyeing cycle, poor dyeing uni...
