Polyester fabric water-saving type continuous pretreatment processes and device thereof

Abstract

The invention relates to polyester fabric water-saving type continuous pretreatment processes and a device thereof, and belongs to the technical field of polyester fabric pretreatment processes. The polyester fabric water-saving type continuous pretreatment processes successively comprises an alkali rolling process, a steaming process and a washing process. The alkali rolling process is carried out by using two process tanks, and a five-dip-single-nip mode is adopted by each process tank. The steaming process is carried out by using a steam box with two layers of conveyer belts, and the steaming temperature is 80-85 DEG C. The washing process comprises four open-width washing processes, each open-width washing process is carried out in an open-width washer, connecting positions of the adjacent open-width washers are communicated by using pipelines, the open-width washer used for the first open-width washing process is directly connected with an unloading port of the steam box, and the polyester fabric getting out of the steam box directly enters the open-width washer used for the first open-width washing process. Energy consumption is low, and product quality is stable.

Description

technical field [0001] The invention relates to a water-saving continuous pretreatment process and equipment for polyester fabrics, belonging to the technical field of polyester fabric pretreatment processes. Background technique [0002] The conventional pretreatment process of polyester fabric is rope-like and intermittent treatment, which has the advantages of short time and fast adjustment process, suitable for small batches and multiple varieties, but the disadvantages are high water, steam and electricity consumption, large amount of waste water, and unstable quality (tank differ greatly from the cylinder). Contents of the invention [0003] The object of the present invention is to provide a water-saving continuous pretreatment process and equipment for polyester fabrics with low energy consumption and stable quality. [0004] In order to achieve the above object, the technical scheme adopted in the present invention is: [0005] A water-saving continuous pretreat...
