Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of fabric modification and dyeing, in particular to a cationic modification production and application device for improving the utilization rate of cellulose dyeing dyes. Background Art
[0002] Cellulose fibers are mainly divided into two categories: natural cellulose fibers and regenerated cellulose fibers. Natural fibers include plant fibers, animal fibers, and mineral fibers. Regenerated cellulose fibers use natural fibers as raw materials, which are chemically treated to form a textile solution and then reshaped into fibers. Cellulose fibers are widely used due to their soft feel, good moisture absorption, and good dyeing properties. However, the dyeing process has disadvantages such as low dye utilization and poor color fastness, resulting in large amounts of wastewater discharge. This is not only difficult and costly to treat, but also causes significant environmental pollution.
[0003] Cellulose fiber fabrics, represented by cotton, are extremely popular with consumers due to their outstanding comfort and have become the largest dye product used by printing and dyeing companies. However, during the dyeing process, large amounts of inorganic salts, such as sodium sulfate or table salt, must be added to the dye liquor to increase dye uptake. The resulting large amounts of salt and alkali discharge can cause serious soil and water salinization. This is due to the dye's lack of affinity for cellulose and the electrostatic repulsion between cellulose fibers and dyes, which limits dye uptake. Consequently, traditional cellulose fiber dyeing suffers from low utilization rates, heavy washing burdens, and high chromaticity and salinity in wastewater, all of which have adverse environmental impacts. Utility Model Content
[0004] In view of the problem that a large amount of inorganic salts are added in the existing cellulose fiber dyeing process, the actual utilization rate of cationic modifiers is low, and a large amount of salt and alkali emissions will cause serious water and soil salinization, the utility model provides a cationic modification production and application device for improving the utilization rate of cellulose dyeing dyes. The temperature control device and the refrigeration device are used to control the temperature increase of the modification liquid during the cationic modification process, so that the modifier does not undergo hydrolysis and unnecessary reactions, thereby improving the utilization rate of the modifier in the cationic modification process, and also reducing the pollution emissions to water due to the decomposition of the modifier.
[0005] A cationic modification production and application device for improving the utilization rate of cellulose dyeing dyes includes a separate space, a modified working liquid mixing device, an alkali solution supply device, and a modifier supply device. The separate space includes a modified soaking device and a refrigeration device; a feed port is provided in the modified soaking device, the feed port of the modified soaking device is connected to the modified working liquid mixing device, the modified working liquid mixing device is connected to the alkali solution supply device and the modifier supply device, a flow monitor and a feed flow control valve are provided between the modified soaking device and the modified working liquid mixing device, a modified soaking device temperature detector and a liquid level monitor are provided in the modified soaking device, and a plurality of cloth guide rollers are also provided inside the modified soaking device.
[0006] Furthermore, the feed inlets of the modified impregnation device are arranged on both sides of the cloth guide roller and at one end of the modified impregnation device.
[0007] Furthermore, the feed port is divided into a first feed port and a second feed port.
[0008] Furthermore, the first feed port is connected to the modified working liquid mixing device via a pipeline, and a first flow monitor and a first flow control valve are provided on the pipeline.
[0009] Furthermore, the second feed port is connected to the modified working liquid mixing device via a pipeline, and a second flow monitor and a second flow control valve are provided on the pipeline.
[0010] Furthermore, the cloth guide rollers are arranged in a staggered manner.
[0011] Furthermore, both the alkali solution supply device and the modifier supply device are equipped with refrigeration equipment.
[0012] Furthermore, the temperature detector and the feed flow control valve of the modified impregnation device are electrically connected to the PLC controller.
[0013] The beneficial effects of the present invention are:
[0014] The utility model provides a cationic modification production and application device for improving the utilization rate of cellulose dyeing dyes. The modified impregnation device is placed in a separate temperature-controlled space. This separate space not only protects the modified impregnation device, but also can cool the fibers or fabrics that need to be modified to ensure the stability of the temperature in the modified impregnation device. The temperatures of the modified working liquid mixing device, the modifier supply device and the alkali solution supply device must be strictly controlled. The temperatures among these three parts should be controlled within 15°C. By controlling the temperature, unnecessary consumption and reaction of the modifier are controlled, so that the reaction of the modifier is carried out on the fibers or fabrics, thereby improving the utilization rate of the modifier and reducing the impact of unnecessary consumption and reaction of the modifier on sewage treatment and the environment.
