An intelligent high-speed open-width knitting pre-shrinking combined machine and its pre-shrinking method

Abstract

The invention discloses an intelligent high-speed open-width knitting pre-shrinking combined machine and its pre-shrinking method. , calendering device and cloth receiving device, the bottom of the humidifying device is provided with a water storage tank, the humidifying device is provided with a second cloth guide roller and a spray mechanism, the pre-shrinking device is provided with a heating chamber and a pre-shrinking chamber, and the heating chamber is provided with a There is a third cloth guide roller and a heating assembly. The method includes: machine frame processing, cloth feeding frame and tenter installation, humidification device installation, pre-shrinking device installation, calendering device installation, cloth receiving device installation and pre-shrinking processing. The invention can realize the continuous humidification of the upper and lower surfaces of the cloth, so that the humidity of the cloth surface is uniform, the effect of pre-shrinking is improved, and the glossiness of the cloth is improved. The pre-shrinking method has simple steps and not only improves the humidification effect and pre-shrinking effect of the cloth , and improve the gloss of the cloth, improve the shrinkage effect of the cloth.

Description

technical field [0001] The invention relates to an intelligent high-speed open-width knitting pre-shrinking combined machine and a pre-shrinking method thereof. Background technique [0002] In recent years, with the continuous development of the textile printing and dyeing industry, various new fabrics have been continuously introduced. The fabric from the gray cloth to the finished product needs to be completed through high-quality tentering and pre-shrinking processes, so that the finished fabric produced has a strong, scratchy, Drape, feel good and so on. [0003] Existing open-width knitted fabrics have undergone many dyeing and finishing processes, forming a certain amount of internal stress, resulting in unstable fiber structure and shrinkage in the weft direction. Stress is accumulated in the radial direction due to mechanical stretching and deformation. After the production of large shrinkage, it is necessary to pre-shrink through plain knitting to achieve the purp...

Problems solved by technology

[0003] Existing open-width knitted fabrics have undergone many dyeing and finishing processes, forming a certain amount of internal stress, resulting in unstable fiber structure and shrinkage in the weft direction. Stress is accumulated in the radial direction due to mechanical stretching and deformation. Larger shrinkage after production, it needs to be pre-shrunk through plain knitting to achieve the purpose of shrink-proof

[0004] In the prior art, when the cloth is pre-shrunk, due to the uneven humidification of the cloth, it is easy to affect the subsequent pre-shrinking effect, which in turn affects the gloss and shrinkage of the cloth.
