Tenter setting refers to processing fibers and other fabric products that need to be processed on a stenter setting machine according to the set standards, coordinating the state of the items, making them appear neat and stable, and eliminating some internal stresses , coordinate the state of warp and weft yarns, make the fabric width uniform and stable, and improve the process of weft skew and so on.

The stenter setting machine is very important for the post-finishing of fabrics, plus its performance Superior and unanimously welcomed by related industries. It can meet the set requirements for tenter shaping of chemical fiber fabrics, polyester filaments, polyester low-strength knitted fabrics, cotton knitted fabrics, and blended fabrics with a certain moisture content, and it can be heated and dried at the same time to eliminate part of the stress. It plays a certain role in coordinating the warp and weft status, making the fabric width uniform, flat and stable, and improving the weft skew.
Simply speaking, a stenter setting machine is a device for shaping weaving fabrics. The setting effect is better than ordinary setting machines. It mainly consists of cloth unwinding, slurry point coating, powder coating, upper and lower powder suction, drying room, cooling and winding, pneumatic and electrical control, etc.
The stenter setting machine is often subjected to a relatively large pulling force during use, which will cause its width to become narrower. During the operation, the stenter setting machine is in order to Overcome such unstable situations, so that the size of its products can be well guaranteed.
When the stenter setting machine is adjusting and adjusting the cloth feeding speed to be greater than its speed, it is called shrinkage. The width of the product Shaping is the finishing work after dyeing. This is also a very important process, because in the setting process, some dyeing factories will put a lot of effort into tenter setting in order to process more cloth than the input amount of gray cloth.
This situation occurs mainly because these manufacturers believe that their customers do not understand the original content. During the processing of the stenter setting machine, if it is often subjected to a relatively large force, it is very easy to cause the problem of warp elongation and weft narrowing. Such a situation can easily lead to warp shrinkage.
During the operation of the tenter setting machine, in order to reduce the warp shrinkage of the fabric and make the fabric size Stable performance, if the cloth feeding speed exceeds the vehicle speed, the warp yarns will all retract and the weft direction will be pulled to the specified width.

Stenter finalization The machine is very important for the post-processing of textile products. However, there are some common problems during use.
Frequently Asked Questions
1: The fabric produced by the stenter setting machine is contaminated with color or oil stains or color stains. To solve this problem, the correct operating steps are recommended:
1. Turn off the stenter setting machine and check whether there is this problem before production;
2. If it is found, it must be approved by the squad leader before starting work. If it does not exist originally, issues that should be paid attention to include: Whether the cloth has been dyed before or whether it is a finished product that is easy to stain; whether there are cloth strips on the needle board; whether there is oil on each support rod before entering the oven; whether the chemical materials are uniform when doing whitening or pad dyeing, etc., and based on the actual situation The situation is handled.
2: There are scratches when the tenter setting machine comes out of the cloth. For this problem, you should first check whether there are such problems before. If so, you need to get the approval of the squad leader before starting work. If it is originally If not, you should check whether the cloth in front of the machine is rubbed against hard objects or whether there are burrs on the rollers, and whether the edge holder wheel is pressed too tightly. All of the above will cause scratches on the cloth coming out of the tenter setting machine, and adjustments must be made before starting work.
3: The tenter setting machine has a moon-curved shape when the cloth comes out of the needle, and there are dead wrinkles when rolling. For the same reason, first check whether there are such problems before, and if so, you can start the work after obtaining permission. . If it is not there originally, you need to check whether the needle feeding on the machine is normal. Overfeeding may cause the needle to come off, the edge brush is bad, the edge wheel is too high, the pressure is not adjusted properly, the needle or needle plate is not aligned, and the cloth is not fed properly. Curling, the above will cause problems such as needle loss or curling when the tenter setting machine comes out of the fabric, and it must be repaired before it can start working.
4: When the tenter setting machine comes out of the cloth and the edge is snagging, it is recommended that the correct operation method is: first check whether the needle surface of the needle plate is normal and whether there are any traces of scratches. If the bristles on the brush wheel fall off, it will directly affect the needle surface and cause the needle tip to become hairy. This will cause the problem of snagging on the edge of the fabric produced by the tenter and setting machine, and it needs to be replaced before it can work.

Key points for setting and stopping Stenter setting machine is a type of setting equipment with superior performance and ideal processing effect. . The operations assigned to it also have certain requirements. For example, when shutting down, there are many things that workers need to pay attention to to avoid adverse effects on the equipment. So, do you know what are the key points to pay attention to when shutting down the stenter setting machine? First, for the processed guide cloth, we need to place it on the operating table. Then, select the main control button of the tenter and setting machine’s cloth feed, turn it to red, and at the same time, select “0” to close the upper needle protection entrance button. When the cloth guide head reaches the cloth overfeeding roller, shut down the equipment, and at the same time connect the cloth guide and the guide belt. Turn off the cooling barrel tension motor to “0”.
Then adjust the equipment to the heating system interface. At this time, it is best to adjust the heating temperature to 150 degrees and adjust the power of the circulating fan at the same time so as to remove the remaining residue inside the stenter setting machine.Remove any accumulated moisture, etc. After about thirty minutes, turn off the heating equipment and ensure that the circulation fan and exhaust fan continue to operate until the temperature in the oven drops to within 100 degrees. After these tasks are completed, we turn off the main switch of the power supply connected to the device. Then, the staff should clean the stenter setting machine and pay attention to keeping the working environment clean. During this process, the equipment should also be inspected to ensure that all parts are intact and there are no loose or other abnormalities. At the same time, it is necessary to ensure that the shutdown work is in place, and the work can only be called off after the inspection work is completed. When the stenter setting machine is in operation, the staff needs to adjust the “feed speed” according to the size, thickness and embroidery density of the products being processed. Normally, when the guide cloth passes through the heating area, the guide cloth needs to be inserted into the cloth rolling device. Note that at this time, the quality of the product should be checked and feedback should be provided in a timely manner. If it is not suitable, it should be adjusted in time.
When the shaping work is completed, the heating switch of the equipment should be turned off ten minutes in advance. Then adjust its operation to low-speed operation, and then you need to wait until the temperature of the stenter setting machine equipment drops to about 80°C before you can turn off the main power supply. It should be noted that when the equipment has been working for 60 hours, the covers on both sides of the heating chamber should be opened, the transmission parts should be inspected and cleaned, and lubricating oil should be added as appropriate.
When the stenter setting machine has been working for one hundred hours, the staff need to carefully check the wires, circuits, heating tubes and connecting parts to see if there are any problems such as damage, aging or looseness, and Process in a timely manner. Since this equipment is an electric heating equipment, in order to ensure safety when styling chemical fiber fabrics, reliable grounding should be ensured. </p
