Intelligent high-speed open-width knitting and preshrinking combination machine and preshrinking method thereof

Abstract

The invention discloses an intelligent high-speed open-width knitting and preshrinking combination machine and a preshrinking method thereof. The machine comprises a rack; a cloth feeding frame, a tentering device, a humidifying device, a preshrinking device, a calendaring device and a cloth collecting device are sequentially arranged on the rack from left to right; a water storage tank is arranged at the bottom of the humidifying device; a second cloth guide roller and a spraying mechanism are arranged in the humidifying device; a heating cavity and a preshrinking cavity are formed in the preshrinking device; and a third cloth guide roller and a heating assembly are arranged in the heating cavity. The method comprises the steps of rack machining, cloth feeding frame and tentering device installing, humidifying device installing, preshrinking device installing, calendaring device installing, cloth collecting device installing and preshrinking processing. According to the invention, continuous humidification of the upper surface and the lower surface of cloth can be achieved, so that the humidity of the surface of the cloth is uniform, the preshrinking effect is improved, and the glossiness of the cloth is improved; and the preshrinking method is simple in step, the humidification effect and the preshrinking effect of the cloth are improved, the glossiness of the cloth is improved, and the shrinking effect of the cloth is improved.

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.
