Description

Technical Field

[0001] The invention relates to the technical field of fabric softening and finishing, and in particular to a continuous extra-wide loose open-width cotton fabric wet softening and finishing device and process. Background Art

[0002] Cotton fabrics are also called cellulose fiber fabrics, which mainly refer to fabrics made of cotton fiber, linen fiber, viscose fiber, bamboo fiber, modal, lyocell, etc., and are the main sales force in the current consumer textile market such as clothing and home textiles. Consumers have a constant pursuit of softness and comfort in textiles, and a product with good hand feel and touch is also a prerequisite for consumers to buy.

[0003] Wet softening of cotton fabrics can improve the feel of the fabric and give it a special quality and style. However, there are many problems with traditional wet finishing equipment and processes, mainly the following: (1) Existing industrial washing machines or rope overflow and rope airflow machines are the mainstream equipment for wet finishing. These devices need to pre-cut textile fabrics into sections or cut them into fixed sizes before wet processing. When processing fabrics, they cannot be processed in batches continuously or cannot directly and effectively enter the next process after processing. Some need to be opened and sewn before the next step of production. It is difficult for wet finishing equipment in the existing technology to effectively perform continuous wet finishing on fabrics, especially for extra-wide fabrics. The equipment is difficult to manufacture, and there is a lack of extra-wide ultra-soft finishing equipment on the market.

[0004] (2) The traditional wet finishing bath ratio is large, and the working liquid contains alkali agents, softening agents, enzyme preparations, etc. For example, an industrial washing machine needs about 550-600L of working liquid to process 75kg of fabric, and it also needs to go through specific acid-base neutralization or enzyme inhibition water washing treatment steps. After washing, the working liquid needs to be discharged, resulting in a large waste of water resources and additives, causing pressure on sewage treatment and affecting the environment.

[0005] (3) Traditional wet finishing is prone to scratches on some fabrics. During the washing process, the fabrics are in a disordered state and are easily entangled and pulled. In addition, they collide with metal objects such as the barrel wall in the equipment, which easily forms scratches on the fabrics, affecting the quality of the product and causing certain economic losses. At the same time, traditional wet finishing fabrics are prone to stains. During the drainage process of the washing machine, softening agents, fluff, washing impurities, etc. will gather at the top of the working liquid and even adhere to the fabrics. After drying, they will form defects such as oil stains, which require re-cleaning and other work, causing economic losses.

[0006] (4) Conventional application of softening agents to cotton fabrics is mainly based on the padding method, which is used for large-scale continuous production. This method mainly achieves the effect of uniform liquid feeding and continuous application of softening agents. However, during the padding method of applying softening agents, due to the short contact time between the softening agent and the fabric and the rapid drying process, the softening agent is often limited to the surface, and the softening effect is not ideal. Summary of the invention

[0007] In view of the technical problems in the prior art such as low efficiency, environmental pollution, many defects and unsatisfactory softening effect of wet softening finishing of cotton fabrics, the present invention provides a continuous extra-wide loose flat-width cotton fabric wet softening finishing device and process, which solves the problem that the traditional wet finishing process cannot be processed continuously and avoids the processing method that the fabric needs to be cut into sections.

At the same time, the fabric impact method is adopted and the application form of the softening agent is changed to reduce the occurrence of defects, improve the fluffiness and softness of the fabric, and achieve "super soft" quality.

[0009] Furthermore, the cloth feeding rack is a flat cloth feeding rack.

[0010] Furthermore, a first liquid seal is provided between the cloth inlet rack and the first finishing box, and a second liquid seal is provided between the second finishing box and the cloth outlet rack, so as to seal the cloth inlet and outlet, and effectively solve the technical problem of heat dissipation.

[0011] Furthermore, the first fence and the second fence are both J-shaped.

Furthermore, the distance between the first cloth guide roller and the second cloth guide roller is 4800mm. The present invention adopts a vertical cloth discharging frame, and heightens the opening device. The fabric is introduced by the upper cloth guide roller and discharged from the lower cloth guide roller, which increases the adjustment torque. At the same time, the single opening beater of the existing cloth discharging frame is changed to a double opening beater, and then the fabric width is further opened through two spiral expanders. Finally, the fabric operation is corrected by the cloth discharging centering device, so that the opening production is realized in a short time according to the running speed of the equipment, and the fabric width is fully expanded, the defect generation is reduced, and the next production process is smoothly entered.

[0014] In a second aspect, the present invention provides a continuous ultra-wide loose open-width cotton fabric wet softening finishing process, comprising the following steps: (1) Prepare the softening and finishing working liquid and store it in the J-shaped stacking tank or L-shaped stacking tank; (2) The dyed cotton fabric enters the cloth feeding rack in a flat state, and then passes through the J-shaped stacking trough, the air duct of the wind box processor, and the L-shaped stacking trough in sequence before being discharged from the cloth feeding rack. The running speed of the cotton fabric is 5-30 m / min. At the same time, the cotton fabric with a total length of 50-300 m is stacked in the J-shaped stacking trough and the L-shaped stacking trough; (3) The softening and finishing working liquid stored in the J-shaped stacking trough and the L-shaped stacking trough is circulated and filtered, and the first and second fans are started. By controlling the piston rods of the first and second cylinders to extend, the first and second reversing plates are swung to contact the first and second wind shields on the right side respectively, and the wind enters the first slit A and the second slit A to the left respectively. The fabric in the air duct moves to the left under the influence of the oblique air jet. By controlling the piston rods of the first and second cylinders to retract, the first and second reversing plates are swung to contact the first and second wind shields on the left side respectively, and the wind enters the first and second slit B and the second slit B to the right respectively. The fabric in the air duct moves to the right under the influence of the oblique air jet. The first and second reversing plates are alternately controlled to swing and switch directions to realize the reciprocating motion of the fabric in the air duct, and alternately hit the first fence and the second fence. At the same time, the first spray head and the second spray head spray the softening and finishing working liquid onto the surface of the cotton fabric. (4) After the cotton fabric is discharged from the fabric rack, it is dried and pre-shrunk to obtain the finished product.

[0015] Furthermore, the softening finishing working solution contains a softening aid with a concentration of 10-30 g / L, or contains soda ash with a concentration of 20-30 g / L, or contains cellulase with a concentration of 0.2-1 g / L.

[0016] Furthermore, in step (3), a steam heating coil may be used to heat the softening working liquid as required.

[0017] The principle of wet softening finishing of the present invention is as follows: in conventional softening finishing of existing cotton fabrics, the application of softening aids is mainly based on the padding method, which is used for large-scale continuous production. This method mainly achieves the effect of uniform liquid supply and continuous application of softening aids. However, in the process of applying softening aids by the padding method, since the contact time between the softening aid and the fabric is short, it is impossible to heat up the cotton fabric for a long time, and it is quickly dried. The softening aid is often limited to the surface, and the softening effect is not ideal. The present invention combines an immersion method (immersing fabric in a J-shaped stacking trough or an L-shaped stacking trough) with spray atomization. First, the cotton fabric can be immersed in a liquid containing a softening agent to improve the permeability of the softening agent. The temperature can be raised to treat the cotton fabric for a long time of 5-60 minutes. After the cotton fabric passes through an air box processor, the air box processor provides acceleration for the fabric through high-speed compressed air between two stacking boxes, so that the fabric movement speed ranges from 150 to 400 meters per minute, and the fabric is impacted and slapped on two fences back and forth. While the fibers are gradually opened, the softening agent is applied to the cotton fabric by spray atomization. Since the smaller the softening agent droplets are, the easier it is for them to enter the interior of the yarn fibers from the yarn fiber pores, thereby further improving the softness of the cotton fabric.

[0018] The beneficial effects of the present invention are: (1) The present invention solves the problem that the traditional wet finishing process cannot be processed continuously, avoids the processing method in which the fabric needs to be cut into sections, and the fabric can be fed in and out flat, and continuous production is achieved, thereby improving production efficiency.

[0019] (2) The present invention solves the problem of serious water waste in the traditional wet finishing process, changes the processing form of the water-washing working liquid, recycles it, and avoids discharge, thereby achieving the purpose of energy saving, emission reduction and clean production.

[0020] (3) The present invention changes the application form of the softening agent and combines the air box processor to release high-speed gas to make the fabric collide with the fence, thereby improving the fluffiness and softness of the fabric, reducing defects, and achieving "super soft" quality.
