Problems solved by technology

[0003] In the existing dyeing process, the fiber is directly placed in the dye vat and stirred for dip-dyeing. Generally, oily substances will remain on the surface of the produced fiber. The existence of these substances will cause the dye to not fully contact with the fiber, resulting in poor dip-dyeing effect. At the same time, it is easy to cause poor exhaust dyeing effect due to stacking problems between fibers, so we propose a method to improve the fixation of dyes in fibers

Embodiment 1

[0017] A kind of fixing method that the present invention proposes improves dyestuff in fiber, comprises the following steps:

[0018] S1: Put the fiber material in the cleaning bucket, then pour in clean water, use the heating tube to heat the clean water, and control the heating tube through the temperature controller to control the water temperature. Add alcohol to the clean water at a ratio of 1:100 to 200, then stir the fiber material, and take out the fiber material after stirring for 20 minutes;

[0019] S2: Place the fiber material taken out in S1 in a drying box, use a hot air blower to supply air, and dry it by circulating hot air. The temperature of the hot air is 50-70°C. The humidity outlet is detected by a humidity sensor. When the humidity percentage is 5- 15%, stop drying and remove fibrous material;

[0020] S3: Prepare the dye and pour it into the dyeing vat. The dyeing vat is heated in a water bath and stirred continuously. The temperature of the heat prese...

Abstract

The invention discloses a method for improving fixation of dye in fiber. The method includes the following steps: S1, a fiber material is placed in a cleaning bucket, then clear water is poured into the cleaning bucket, the clear water is heated by a heating tube, the heating tube is controlled by a temperature controller so as to control the water temperature, the heat insulation temperature of the water temperature is 50 to 70 DEG C, alcohol is added into the clear water according to the proportion of 1:(100 to 200) of the alcohol to the clear water, then the fiber material is stirred, and the fiber material is taken out after being stirred for 20 min; and S2, the fiber material taken out in the step 1 is placed in a drying oven, air is supplied by a hot air blower, drying is conducted by circulating hot air, the hot air temperature is 50 to 70 DEG C, a moisture exhaust opening is detected by a humidity sensor, when the humidity percentage is 5% to 15%, drying is stopped, and the fiber material is taken out. The operating process is simple, and meanwhile, fixation of the dye on the fiber can be greatly improved.

Description

technical field [0001] The invention relates to the technical field of dyeing, in particular to a method for improving the fixation of dyes in fibers. Background technique [0002] Immerse the fiber in the dye aqueous solution at a certain temperature, and the dye will move from the water phase to the fiber. At this time, the amount of dye in the water will gradually decrease, and after a period of time, it will reach an equilibrium state. The dye that is reduced in the water is the dye that moves onto the fiber. When the fiber is taken out at any time, even if it is twisted, the dye remains in the fiber, and the dye cannot be completely separated from the fiber. The phenomenon that the dye is combined in the fiber is called dyeing. [0003] In the existing dyeing process, the fiber is directly placed in the dye vat and stirred for dip-dyeing. Generally, oily substances will remain on the surface of the produced fiber. The existence of these substances will cause the dye to...
