Description

Technical Field

[0001] The utility model relates to the technical field of mercerizing equipment, in particular to a mercerizing processing device for producing ultra-fine cool feeling fabrics. Background Art

[0002] Cool feeling fabrics adopt unique processes to enable the fabrics to quickly dissipate body heat, accelerate the discharge of sweat and reduce body temperature, and permanently maintain the function of keeping the fabric cool and comfortable. This is a new innovation in the fabrics for sportswear and outdoor casual wear. Cool feeling fabrics will provide people with a living quality of comfortable and environmentally friendly clothing and ice-cold feeling. They are applicable to textile industries such as sports, military, and medical fields, and are cold feeling technology fabrics for resisting heat and reducing temperature.

[0003] Mercerizing refers to the process of treating fabrics with strong caustic soda solution in a relaxed state. The purposes of mercerizing and mercerizing are different. Its main purpose is not to obtain luster, but to increase the tissue density and elasticity of the fabrics. In the processing technology of cool feeling fabrics, mercerizing equipment is required to carry out mercerizing processing on the fabrics, so mercerizing processing equipment is needed.

[0004] When the existing mercerizing processing equipment is in use, it relies on a single alkali liquid tank for mercerizing treatment and lacks a pretreatment stage, which easily leads to uneven distribution of the alkali liquid and inconsistent mercerizing degrees of each part of the fabric; hard tools such as extrusion plates may be used to remove the excess alkali liquid, which easily causes scratches or damages to the surface of the fabric. Especially for ultra-fine cool feeling fabrics with sensitive surfaces, the damage will lead to a decline in the cool feeling characteristics; a large amount of alkali liquid is directly discharged after treatment, which not only increases the production cost but also causes a certain burden on the environment. Summary of the Utility Model

[0005] In view of the above problems, the utility model discloses a mercerizing processing device for producing ultra-fine cool feeling fabrics.

[0006] The technical solution of the utility model is: a mercerizing processing device for producing ultra-fine cool feeling fabrics, including an alkali liquid tank, a spraying unit and a filtrate unit respectively arranged on the left and right sides of the alkali liquid tank;

[0007] The spraying unit includes a spraying box with an open structure on the side close to the alkali liquid tank, spraying pipes arranged at the upper and lower ends of the spraying box, a liquid suction pipe for connecting the spraying pipes and the alkali liquid tank, and a strip-shaped inlet arranged on the side of the spraying box opposite to its open structure;

[0008] The filtrate unit includes a filtrate box with an open structure on the side close to the alkali liquid tank, a strip-shaped filtrate port arranged on the side of the filtrate box opposite to its open structure, and filtrate brushes arranged at the upper and lower ends of the strip-shaped filtrate port; first guide rollers are arranged inside and outside the filtrate box and the spraying box, and second guide rollers are arranged on the left and right sides inside the alkali liquid tank.

[0009] Further, a first filter box is movably connected to the lower side of the opening of the spray box, and a second filter box is movably connected to the lower side of the opening of the filtrate box.

[0010] Explanation: After the superfine cool-sensation fabric is treated by the spray unit, the sprayed alkali solution flows back to the alkali solution tank through the opening of the spray box for reuse. At this time, the impurities in the sprayed alkali solution are filtered by the first filter box to avoid scratching the surface of the superfine cool-sensation fabric during reuse. After the alkali shrinkage treatment of the superfine cool-sensation fabric is completed, the alkali solution will flow back to the alkali solution tank through the opening of the filtrate box for reuse after being squeezed by the filtrate brush. The second filter box filters the impurities in the alkali solution, and its function is the same as that of the first filter box, which not only ensures the reuse of the alkali solution, saves energy and reduces emissions, but also ensures the alkali shrinkage effect.

[0011] Further, a protective outer tank is provided on the outer wall of the alkali solution tank. A heating cavity is formed between the protective outer tank and the alkali solution tank. The protective outer tank is connected to a constant-temperature heating box through a connecting pipe, and a constant-temperature heater is provided in the constant-temperature heating box.

[0012] Explanation: When the alkali shrinkage treatment is carried out on the superfine cool-sensation fabric, the water added to the constant-temperature heating box is heated at a constant temperature by the constant-temperature heater. Then, the heated water is pumped into the heating cavity, and the alkali solution in the alkali solution tank is heated at a constant temperature through heat conduction, ensuring that the temperature of the alkali solution in the alkali solution tank remains at a preset constant value, avoiding the influence of temperature fluctuation on the alkali shrinkage treatment effect, and ensuring the consistency and stability of the treatment of the superfine cool-sensation fabric.

[0013] Further, a mixing and stirring frame is provided in the alkali solution tank and located between the two second guide rollers. The mixing and stirring frame is driven by a rotating motor, and a plurality of constant-temperature heating rods are evenly provided on the outer wall of the mixing and stirring frame.

[0014] Explanation: In order to improve the heating uniformity of the alkali solution in the alkali solution tank, effectively promote the circulation and flow of the alkali solution, and prevent the precipitation of the alkali solution, the mixing and stirring frame is driven by the rotating motor to rotate and stir. At the same time, heating is carried out through the constant-temperature heating rods to maintain the mixing uniformity, thereby ensuring the quality of the alkali shrinkage processing.

[0015] Further, it further includes a winding roller assembly located on the filtrate box and close to one side of the strip-shaped filtrate port. The winding roller assembly includes two winding placement frames symmetrically distributed front and back and having clamping cavities on the opposite sides, and a winding roller clamped to the two clamping cavities on both sides.

[0016] Explanation: The superfine cool-sensation fabric removed from the strip-shaped filtrate port can be wound around the winding roller for winding. After winding is completed, the winding roller is directly taken out from the clamping cavity for transfer, avoiding additional handling and sorting steps, greatly shortening the production cycle, and improving the production efficiency.

[0017] Advantages of the present utility model:

[0018] When the caustic shrinking processing equipment for producing ultra-fine cool feeling fabric of the present utility model is in use, the ultra-fine cool feeling fabric is pre-treated by spraying caustic soda through the spraying unit, and the caustic soda solution can be quickly and evenly attached to the surface of the fabric, laying a foundation for the subsequent deep caustic shrinking treatment. Then, the secondary caustic shrinking treatment is carried out in the caustic soda solution tank. By combining the spraying pretreatment and the treatment in the caustic soda solution tank, the uniformity of the fabric in different treatment stages can be ensured, avoiding the fabric quality problems caused by uneven local treatment. The excess caustic soda solution on the surface of the treated ultra-fine cool feeling fabric is brushed off by the filtrate brush, avoiding the subsequent treatment problems or the decline of fabric quality caused by the residual caustic soda solution; since the filtrate brush is made of soft material, it can gently contact the surface of the fabric, avoiding the scratches that the pressing plate may cause to the ultra-fine cool feeling fabric, and protecting the delicate texture and cool feeling characteristics of the fabric; in the above treatment process, the excess caustic soda solution after the spraying caustic shrinking treatment and on the surface of the ultra-fine cool feeling fabric will be collected back into the caustic soda solution tank for recycling, saving the consumption of caustic soda solution and reducing the processing cost.

After the superfine cool-sensing fabric is spray-treated by the spraying unit 2, the sprayed lye flows back to the lye tank 1 through the opening of the spraying box 21 for reuse. At this time, impurities in the sprayed lye are filtered by the first filter box 211 to avoid scratching the surface of the superfine cool-sensing fabric during reuse. After the alkali shrinking treatment of the superfine cool-sensing fabric is completed, the lye will flow back to the lye tank 1 through the opening of the filtrate box 30 for reuse after being squeezed by the filtrate brushes 32.

The protective outer tank 11 is connected to a constant-temperature heating box 13 through a connecting pipe. A constant-temperature heater 130 is provided in the constant-temperature heating box 13. When the superfine cool-sensing fabric is subjected to alkali shrinking treatment, the water body added to the constant-temperature heating box 13 is heated to a constant temperature by the constant-temperature heater 130. Then, the heated water body is pumped into the heating chamber 12, and the lye in the lye tank 1 is heated to a constant temperature through heat conduction, ensuring that the temperature of the lye in the lye tank 1 remains at a preset constant value, avoiding the influence of temperature fluctuations on the alkali shrinking treatment effect, and ensuring the consistency and stability of the treatment of the superfine cool-sensing fabric. Among them, the constant-temperature heater 130 adopts existing technologies;

[0029] Inside the lye tank 1 and between two second guide rollers 10, there is a mixing and stirring frame 14. The mixing and stirring frame 14 is driven by a rotating motor.

The ultra-fine cool-sensing fabric removed from the strip-shaped filtrate port 31 can be wound around the winding roller 52 for winding. After winding is completed, the winding roller 52 is directly taken out from the clamping cavity 50 for transfer, avoiding additional handling and sorting steps, greatly shortening the production cycle, and improving the production efficiency. Among them, the winding roller 52 adopts the existing technology.

[0033] S2. The lye in the lye tank 1 is pumped into the spray pipe 22 through the liquid suction pipe 23 and evenly sprayed onto the upper and lower ends of the fabric to be processed to complete the pre-treatment of spray caustic shrinking. The processed lye flows back into the lye tank 1 through the opening of the spray box 21 for repeated use. At this time, impurities in the spray lye are filtered by the first filter box 211;

[0034] S3. The part of the fabric after the pre-treatment of spray caustic shrinking in the spray box 21 is transferred to the lye tank 1 through the respective first guide rollers 4 and second guide rollers 10, and is subjected to secondary caustic shrinking treatment with the lye in the lye tank 1.
