Working principle of pre shrinking machine

With people's higher and higher requirements for clothing styles and styles, preshrinking technology is also constantly improving and developing, thus the pre shrinking machine products used in this technology were born. The main function of the preshrinking machine is to adjust the warp shrinkage of the fabric by using mechanical physical methods, so as to eliminate the shrinkage effect of the fabric, and improve the handle and luster of the fabric to a certain extent. Under normal circumstances, the preshrinking machine can be used for preshrinking of blended fabrics, woolen fabrics, chemical fibers and pure cotton fabrics. Its working principle is as follows:

After dyeing and finishing, the fabric will be in a potential shrinkage state. This kind of clothing made of woven fabric is easy to deform after washing, which will bring consumers a certain degree of loss and bad shopping experience. In order to prevent this kind of problem, the fabric should be pretreated by the conventional pre shrinking machine. Under certain pressure, humidity and temperature, the pre shrinking machine can eliminate the potential shrinkage of the fabric by virtue of the elastic shrinkage deformation of the fabric itself and the penetration and swelling principle of the fabric and chemical fiber, so as to improve the handle and appearance of the fabric.

The potential shrinkage of clothing or other fabrics treated by pre shrinking machine has been eliminated, which has an obvious effect on improving the performance of clothing or other fabrics. For pre shrinking technology, in addition to mechanical pre shrinking machine, there is also chemical pre shrinkage, which depends on the fabric fiber, so in this respect, we need to depend on the situation. Of course, at present, most of the fabric pre shrinkage is mainly physical shrinkage, which is commonly referred to as mechanical shrinkage.
