Desizing system of printing and dyeing fabric

Abstract

The invention discloses a desizing system for printed and dyed fabrics, which comprises a support frame body, a desizing tank is installed in the support frame body, the desizing tank is arranged at the lower part of the support frame body, and the cloth feeding end at the upper part of the support frame body is provided with a guide Cloth rollers, friction cloth feed rollers, active cloth feed rollers, the support frame above the cloth inlet of the desizing tank has a walking track, a left and right trolley is installed on the travel track, and a cloth discharge correction device is installed on the cloth discharge end of the support frame , cloth pressing roller and cloth pulling roller; the section of the liquid tank of the desizing tank is L-shaped structure, the lower part of the desizing tank is provided with an orifice plate, and the lower part of the orifice plate is equipped with a steam heating tube, and the steam heating tube is equipped with multiple hole. The invention is equipped with an L-shaped desizing tank, which effectively reduces the use of desizing liquid and saves energy consumption; a direct heating tube is installed at the bottom of the box to make the desizing temperature 40-70 °C, and the paste and additives on the fabric swell The effect is better; the left and right trolley adopts telescopic springs to adjust the gap between the left and right rollers, the structure is simple, and the adjustment is timely.

Description

[0001] Technical field: [0002] The invention relates to the technical field of printing and dyeing fabric production equipment, in particular to a desizing system for printing and dyeing fabrics. [0003] Background technique: [0004] Desizing of printed and dyed fabrics refers to the process of removing sizing on fabrics. The warp yarns of fabrics such as cotton, viscose and synthetic fibers are mostly sizing before weaving. Sizing affects fabric wettability during dyeing and finishing and hinders chemical contact with fibers. Therefore, fabrics are generally desized first. Cotton fabric desizing also has the function of removing some impurities in the fiber; synthetic fiber fabrics can sometimes be desized simultaneously during the scouring process. The desizing tank in the existing desizing system is too large, which wastes water, especially the fabric and water exchange time is too short, the electrical control has not achieved complete automation, it is difficult to ...

AI Technical Summary

Problems solved by technology

The desizing tank in the existing desizing system is too large, which wastes water, especially the fabric and water exchange time is too short, the electrical control has not achieved complete automation, it is difficult to completely soak and swell, and it increases the cost for the next oscillation washing process. Difficult, not easy to clean, resulting in heavy waste of water
