Problems solved by technology

[0003] The above-mentioned loose fiber dyeing method and system has its advantages and characteristics, but its single-cylinder treatment, the degree of continuity is not high, the production cost is high, the production efficiency is relatively low, and the labor intensity is high; the fibers are in a piled state, and some impurities are removed in the pre-treatment Dirty, dyeing is opaque and uneven, the dyeing effect is poor, and the low utilization rate of dyeing materials still needs to be improved; the degree of automation of the dyeing system is low

[0025] The loose fiber wet-short-steam dyeing system described in Example 1 includes a cotton grabbing machine 1, a web forming machine 2, a padding tank 3, a reaction box 4, a washing tank 5, an opening machine 6, a conveying fan 7, and a drying tower 8 And the fiber packaging device 9, the cotton grabbing machine 1 is connected to the entrance of the web forming machine 2 through a pipeline, and the padding tank 3, the reaction box 4, the washing tank 5 and the fiber opening machine 6 are distributed in the web forming machine 2 successively in an assembly line. On the outlet side, the outlet of the fiber opener 6 is connected to the inlet of the delivery fan 7 through a pipeline, the outlet of the delivery fan 7 is connected to the lower end of the drying tower 8 through a pipeline, and the upper end of the drying tower 8 is connected to the fiber packaging device 9 through a pipeline. The reaction box 4 contains an infrared heater 4.1, a hot air steam inlet 4.2 and a transf...

Embodiment 2

[0035] The loose fiber wet short steam dyeing system described in embodiment 2 is the same as embodiment 1.

[0036] The following is an example of dyeing cotton fiber with Argosol Red N-SB reactive dye in our bulk fiber wet short steam dyeing system:

[0037] Step 1. The cotton fiber is transported to the web forming machine 2 through the plucking machine 1, and the cotton fiber forms a uniform fiber layer with a width of 1.5m in the web forming machine 2, and the output speed of the fiber layer is 35m / min;

[0038] Step 2. Let the fiber layer formed in step 1 be dyed through the padding tank 3, the temperature of the padding solution is 30°C, the dyeing solution rate is controlled at 70%, and the dye prescription is: Argosol Red N-SB 2g / L , penetrant NF 1g / L, anti-swimming agent FR-MIV 3g / L, anti-staining salt Ludigol 1g / L;

[0039] Step 3. Make the fiber layer after padding in step 2 enter the reaction box 4 for reaction and color fixation. After the fiber layer passes thr...

Embodiment 3

[0045] The loose fiber wet short steam dyeing system described in embodiment 3 is the same as embodiment 1.

[0046] The following is an example of dyeing viscose fiber with Remazol Red RGB reactive dye in our bulk fiber wet short steam dyeing system:

[0047]Step 1. The viscose fiber is transported to the web forming machine 2 through the plucking machine 1, and the viscose fiber forms a uniform fiber layer with a width of 1.8m in the web forming machine 2, and the output speed of the fiber layer is 40m / min;

[0048] Step 2. make the fiber layer formed in step 1 be dyed through the padding tank 3, the temperature of the padding solution is 25°C, the dyeing solution rate is controlled at 70%, the dyestuff prescription is: remazol red RGB 10.8g / L, penetrating agent NF 1g / L, anti-swimming agent FR-MIV 5g / L, anti-staining salt Ludigol 1g / L, soda ash 10g / L;

[0049] Step 3. Make the fiber layer after padding in step 2 enter the reaction box 4 for reaction and color fixation. Afte...

Abstract

The invention discloses a method and a system for shortened wet steaming dyeing of loose fibers. The method and the system have the advantages that continuous production of loose fiber dyeing is realized, so that production cost is lowered, production efficiency is improved, and labor intensity is lowered; shortened wet steaming technology which can save energy and reduce emission is applied to dyeing of the loose fibers, the dyeing process is simple, convenient, high in efficiency and energy saving, setting rate is high, dyeing effect is good, and dyestuff is high in utilization rate and environment friendly; automatic level of the dyeing system is increased.

Description

technical field [0001] The invention relates to a dyeing method and system, in particular to a wet short steam dyeing method and system for loose fibers. Background technique [0002] The loose fiber dyeing method was originally used for the dyeing of wool and acrylic fibers, and it is a relatively traditional process for wool dyeing in the wool spinning industry. The bulk fiber dyeing system is mainly composed of a main vat, a dyeing cage, and a main pump. This type of dyeing vat has the characteristics of low price, easy operation, compact structure, and small footprint. Compared with fabric dyeing, bulk fiber dyeing has a lower bath ratio, less dyeing and chemical materials, less water and sewage for dyeing, lower power consumption and steam consumption, and obvious energy saving and environmental protection. The color-spun yarn dyed with dispersion fibers fully mixed in different colors can show multiple colors on the same yarn, and the colors are rich. The fabric compo...
