The workflow damp of the fabric treatment by the hot and humid shrinking machine
After the fabric is processed, it will maintain a certain state because of the characteristics of its raw materials. In order to obtain the more stable fabric size, the fabric needs to be further processed, which is also done by the mechanical equipment, such as the hot and humid shrinking machine.
The hot and humid shrinking machine can do preshrunk process for the cellulosic fabrics, such as cotton, linen, silk and viscose rayon. These fabrics have a common characteristic. Their hygroscopicity is so large that the fibre will easily swell and then shorten the fibre length, which will affect the stability of the fabric and the blend fabric size.
But there is no need to worry after having the hot and humid shrinking machine. the pinch effect of the fabric can achieve that the washing shrinkage in warp and weft direction is less than 3% through the equipment. In addition to obtaining a stable external dimension, the hot and humid shrinking machine can improve the handle and impression of the fabric to make the fabric reach a certain weight and stiffness requirements.
The hot and humid shrinking machine adopts the basic operation flow of squirting, squeezing and drying. It can make the fabric achieve the desired effect according to the corresponding requirements strictly. The hot and humid shrinking machine can be divided into the rubber blanket hot and humid shrinking machine and the woolen blanket hot and humid shrinking machine according to the clad material. However their working principle is the same.
Fix the fully wet fabric between the roller and the heating pressure roller of the hot and humid shrinking machine, and make it enter the surface of the heating pressure roller of the hot and humid shrinking machine through the cladding of the rubber blanket or woolen blanket. At this time, the rubber blanket or woolen blanket will be bent between the roller and the heating pressure roller, then stretching in outer sphere and squeezing in the inner shell.
At the same time, making the use of the good elastic deformation of the rubber blanket and woolen blanket, the fabric is squeezed and cladded tightly between the rubber blanket and the heating pressure roller. The fabric is squeezed and shrinked, drying, to achieve the purpose of shrinking.
