Desizing system of printing and dyeing fabric

Abstract

The invention discloses a desizing system of a printing and dyeing fabric. The system comprises a support frame body, a desizing groove is installed in the support frame, the desizing groove is arranged on the lower portion of the support frame body, a cloth inlet end of the upper portion of the support frame body is provided with a cloth guide roller, a friction cloth inlet roller and an active cloth delivery roller. The portion, located above the cloth inlet of the desizing groove, of the support frame body is provided with a walking rail, a small cloth placement vehicle is installed on the walking rail, and the cloth outlet end of the support frame body is provided with a cloth outlet correction device, a cloth press roller and a cloth outlet traction roller; a liquid groove section of the desizing groove is of an L-shaped structure, a pore plate is arranged on the lower portion of the desizing groove, a steam heating pipe is installed on the lower portion of the pore plate, and several holes are formed in the steam heating pipe. Through the arrangement of the desizing groove of the L-shaped structure, the use of desizing liquid is effectively reduced, and the energy consumption is reduced; a direct-heating pipe is arranged on the bottom of a tank body, so that the desizing temperature is 40-70 DEG C, and the swelling effects of auxiliaries and paste materials on the fabric are more excellent. The small cloth placement vehicle adopts a telescopic spring to adjust a gap between every two cloth placement rollers, the structure is simple, and the adjustment is conducted in time.

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
