Case sharing of stenter setting machine burner pre-setting and final product finalization

For some fabrics, it is often necessary to use stenter setting machine burner equipment for pre-processing before dyeing and printing. . The advantage of this is that it can reduce undesirable phenomena such as pull marks. For example, when processing stretch fabrics, because of its relatively high content of spandex, spandex and silk shrink differently, and the silk is harder than other raw materials. If the stenter setting machine burner is not used for pre-sizing, it is very likely in the later printing and dyeing process. There will be imprints etc. In addition, there are many finished products that also need to be shaped by the burner equipment of the stenter setting machine. For example, for nylon fabric, in the process of this treatment, the setting temperature should be kept between 160°C and 180°C, and the setting speed should be controlled between 20 meters and 25 meters per minute. At the same time, it is necessary to reasonably control the setting temperature of the burner of the stenter setting machine. This is because the setting temperature has great changes in color, especially purple, pink blue, etc., so pay attention to whether the color before and after treatment is the same. Also note that the thickness of nylon fabric is different, so the shrinkage rate is also different. Nylon fabrics are easy to hook yarn after shaping. If there is an end-to-end yarn hook after shaping, you should stop the machine immediately and check the head and tail, bellows, drum, sanding with sandpaper, or pad cloth. In addition, in the process of setting and finishing the polyester fabric with the burner equipment of the stenter setting machine, the low-temperature burner generally controls the setting temperature between 170°C and 200°C, and the setting speed is 20 to 28 meters per minute. It should be noted that in the process of setting and finishing polyester Bobbi cloth, the setting temperature of the burner of the stenter setting machine must be reasonably controlled. At the same time, the thickness of the middle and the side of the cloth and the slow speed of the machine must be considered. Pull twice. This is because the difference in thickness of the middle edge can be reduced by piding it twice. If you are interested in low temperature burners, please contact us for a quote!
