Embodiment 1
[0023] The present embodiment pours and rolls the loose fiber dyeing machine, combines figure 1 , including a transmission part and a spraying part, the transmission part includes a pair of upper driving rollers 3 and a pair of lower driving rollers 4, the upper driving rollers 3 and the lower driving rollers 4 are respectively sleeved with an upper guide belt 5 and a lower guide belt for use together 6. There is a leakage hole 1 on the upper guide belt 5, and the upper guide belt 5 and the lower guide belt 6 run synchronously. Several upper rolls 7 are installed in the upper guide belt 5 circuit, and several rollers 7 are installed in the lower guide belt 6 circuit. The lower roller 8 used in conjunction with the upper roller, the upper guide belt 5, the lower guide belt 6, the upper roller 7, and the lower roller 8 cooperate to realize the synchronous clamping and conveying of loose fibers; the spraying parts include the spraying head 9 and the dyeing liquid pipe 10. One end...
Embodiment 2
[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...
