Detailed explanation of the super-feeding technology of textile stenter machine

- Jul 05, 2019-

In the dyeing and finishing process of textile, the warp direction is subjected to a large pulling force, resulting in the elongation of the length and the narrowing of the width. In order to overcome this unstable state and ensure the dimensional stability of the textile , the speed of the cloth is adjusted when the tenter is stretched or shaped by the textile stenter machine, which is super feed.


The speed of the cloth feeding is higher than that of the textile stenter machine. It is called super-feeding. The over-feeding makes the warp yarn retract, the weft density rises, the weight increases, and the warp shrinkage decreases. If the speed of the cloth feeding is less than the speed of the textile stenter machine, it is called anti-overfeeding. The anti-overfeeding causes the warp yarn to elongate, the weft density decreases, the gram weight decreases, and the warp direction shrinks.


The tenter setting of the textile stenter machine is a finishing work after dyeing, and it is also a very important process. In the process of tenter shaping, in order to reduce the warp shrinkage rate of the fabric, the fabric size is stable. When the tentering or setting is performed, the super-feeding is carried out, and the speed of feeding is greater than the speed of the tenter or the setting machine, so that the warp yarn is all Retract, pull the latitude to the specified
