One-bath desizing and dyeing device for polyester fabric containing sizing agent

Abstract

The invention discloses a one-bath desizing and dyeing device for a polyester fabric containing a sizing agent, and belongs to the technical field of desizing and dyeing. The device comprises a sizingagent receiving pool; sizing agent receiving holes are formed in the faces, away from each other, of the front ends of the left side and the right side of the sizing agent receiving pool; lower roller shafts are movably installed in the sizing agent receiving holes; the outer circles of the left end and the right end of each lower roller shaft are sleeved with first baffle rings; the first bafflerings are circular rings and are located on the outer side of the sizing agent receiving pool; the lower roller shafts transversely penetrate through the interiors of the first baffle rings; two groups of first snap rings are fixedly installed on the outer circles of the lower roller shafts; the first snap rings are circular rings and are located on the inner side of the sizing agent receiving pool; the lower roller shafts transversely penetrate through the interiors of the first snap rings; and lower pressing roller sleeves sleeve the outer circles of the middles of the lower roller shafts and are located between the two groups of first snap rings. According to the device, the sizing agent on the polyester fabric is extruded and discharged through mutual extrusion of upper roller shaftsand the lower roller shafts, so that manual cleaning and sizing agent removal are not needed, and the labor force is reduced.

Description

technical field [0001] The invention belongs to the technical field of desizing and dyeing, and in particular relates to a one-bath desizing and dyeing device for polyester pulp-containing fabrics. Background technique [0002] Polyester, or polyester fiber, was invented in 1941 and is an important variety of synthetic fibers. Polyester is a fiber-forming polymer made from purified terephthalic acid (PTA) or dimethyl terephthalate (DMT) and ethylene glycol (MEG) through esterification or transesterification and polycondensation reactions. The biggest advantage of the fiber made by spinning and post-processing is that it has good wrinkle resistance and shape retention. Polyester has a wide range of uses and is widely used in the manufacture of clothing and industrial products. Due to its permanent flame retardancy, flame-retardant polyester has a wide range of applications. In addition to its irreplaceable role in industrial textiles, architectural interior decoration, and ...

AI Technical Summary

Problems solved by technology

[0003] The disadvantages of existing desizing equipment on the market are that a large amount of labor is required to desizing textiles, and the desizing process is too cumbersome, which seriously reduces production efficiency. The washing process of desizing produces a large amount of sewage, which also affects the environment. It has a great impact, and because of the need for manual desizing, the washing water will also cause serious damage to the human body
