Polyester fabric continuous desizing pretreatment method and device

Abstract

The invention provides a polyester fabric continuous desizing pretreatment device, and belongs to the technical field of desizing devices. The polyester fabric continuous desizing pretreatment devicecomprises a desizing box and a cyclic utilization device. A connecting pipe is arranged between the desizing box and the cyclic utilization device, and the desizing box communicates with the cyclic utilization device through the connecting pipe. Steering rollers are arranged in the desizing box and located in the desizing box in a front-back mode, desizing rollers are arranged below the steering rollers and located in the desizing box in a front-back mode, and rotating shafts are arranged on the steering rollers and the desizing rollers front and back in a penetrating mode. According to the polyester fabric continuous desizing pretreatment device, through cooperation of an auxiliary desizing device, a layering device and a linkage winder, when a cam rotates, a linkage rod can drive the linkage winder to rotate, after coil spring plates are paved fully, the slurry water at the bottom can be separated from the slurry water at the upper layer, so that the slurry water at the bottom is discharged after being precipitated, auxiliary desizing can be carried out by using a clean solution during desizing, and the slurry water cannot be adhered to the fabric again.

Description

technical field [0001] The invention belongs to the technical field of desizing devices, in particular to a continuous desizing pretreatment device for polyester fabrics. Background technique [0002] Desizing refers to the process of treating the fabric with acid, alkali, enzymes, etc. to remove the sizing rhyme added to the warp yarn during weaving. The purpose is to facilitate subsequent processing such as scouring. Before the fabric is weaved, the warp yarns are generally subjected to sizing treatment (the warp yarns are dipped in the sizing solution and then dried), so that the fibers in the yarns are adhered to each other, and a thin film is formed on the surface of the yarns, which is convenient for weaving. Cotton fabrics are generally sized with starch or modified starch size or polyvinyl alcohol and polyacrylic acid (ester) size, and lubricants, softeners, preservatives and other additives are also added to the size, but the existing desizing device is desizing W...

Problems solved by technology

Cotton fabrics are generally sized with starch or modified starch size or polyvinyl alcohol and polyacrylic acid (ester) size, and lubricants, softeners, preservatives and other additives are also added to the size, but the existing desizing device is desizing When sizing, the desizing water will be kept in the desizing box, which will cause the desizing effect of subsequent fabrics to deteriorate, resulting in the need to desizing the fabrics again, seriously affecting work efficiency
