Description

Technical Field

[0001] The invention relates to the technical field of printing and dyeing equipment, in particular to a steam color fixing device for low-water printing and dyeing and a color fixing process thereof. Background Art

[0002] After textile printing, except for ice dyes and soluble vat dyes, general dyes must be evaporated. The purpose is to allow the printed textiles to complete the moisture absorption and temperature rise of the fibers and color paste films, accelerate the reduction of the dyes and their dissolution on the fibers, and allow the dyes to diffuse into the fibers and fix on the fibers. The evaporation process conditions vary with the properties of the dyes and fibers.

[0003] During the steaming process, steam first condenses on the textile, followed by a rapid rise in the temperature of the textile. At the same time, the fiber absorbs moisture and swells. After the color paste absorbs water, it accelerates the full dissolution of the dye and chemical agent, which is beneficial to the occurrence of chemical reactions, prompting the dye to transfer from the color paste to the fiber and diffuse into the fiber to produce color fixation. The main factors affecting the moisture absorption of the color paste are the temperature and relative humidity in the steamer. However, most of the existing steam treatment equipment is an integrated structure. When the textile fabric enters the steam treatment equipment for steaming, the temperature of the textile fabric can quickly reach the ambient temperature in the steam treatment equipment. At this time, the steam can no longer continue to condense on the textile fabric, so that the humidity of the textile fabric is low and remains constant, which affects the moisture absorption effect of the fiber, and then affects the steaming effect, which is not conducive to the color fixation of the textile fabric.

[0004] Therefore, in view of this, the existing structural deficiencies are studied and improved, and a steam color fixing device and a color fixing process for water-saving printing and dyeing are proposed. Summary of the invention

[0020] The present invention provides a steam color fixing device for low-water printing and dyeing and a color fixing process thereof, which has the following beneficial effects:

[0021] 1. When the present invention is in use, in the process of high-temperature steam passing through the steam pipe, on the one hand, the impeller group converts part of the thermal energy into mechanical energy under the impetus of steam and drives the transmission rod to rotate, and further the coaxial bevel gear in the middle of the transmission rod is connected to the transmission belt through the bevel gear rod, driving the three transmission rollers in the triangular structure to rotate synchronously, and realizing the continuous feeding of the cloth body under the cooperation of the tensioning roller, on the other hand, the coaxial flywheel at the end of the transmission rod is connected to the sliding sleeve through the eccentric connecting rod, and the longitudinal reciprocation of the sliding sleeve further drives the swing arm at the end of the water-cooled plate to swing back and forth through the ear shaft, and the cloth body discharged from the steamer body and cooled by the water-cooled plate heat exchange is stacked.

[0022] 2. When the present invention is in use, on the one hand, the soft water in the interlayer is preheated and flows back to the water inlet pipe through the soft water outlet, which reduces the energy consumption required for the boiling evaporation of the generator and plays a role in water saving. On the other hand, the liquefied condensed water is passed into the heat exchanger through the transfer interface. Through the pre-soaked wet curtain, not only the condensed water passing through the serpentine tube is further cooled, but also the wind blown by the blower fan is cool and moist. The intermittent cooling area of ​​the fabric body is blown through the reserved holes of the steamer body, so that the fabric body is lower than the ambient temperature in the steamer body, and the intermittent cooling is The cold air required for the temperature still comes from the cold energy generated by the condensation of steam.

Through multiple intermittent cooling and steam heating, the pigment is firmly attached to the cloth body 4, thereby improving the efficiency of yarn printing and dyeing. Moreover, the cold air required for intermittent cooling still comes from the cold generated by steam condensation.
