Desizing, scouring and bleaching one-bath process system and method for pure cotton woven fabric short-process pretreatment

Abstract

The invention discloses a desizing, scouring and bleaching one-bath process system and method for pure cotton woven fabric short-process pretreatment, and relates to the technical field of cloth production. The desizing, scouring and bleaching one-bath process system comprises a bottom plate, a desizing bin, a scouring bin and a bleaching bin are fixedly connected with the top of the bottom plate in sequence from left to right, and a reciprocating stirring mechanism is arranged in the desizing bin; and the reciprocating stirring mechanism comprises a rotating rod rotationally connected between the front side and the rear side of the inner wall of the desizing bin, and the rear end of the rotating rod penetrates through the desizing bin and extends to the rear side of the desizing bin. According to the desizing, scouring and bleaching one-bath process system and method for pure cotton woven fabric short-process pretreatment, by arranging the reciprocating stirring mechanism, desizing liquid is stirred and mixed by a stirring paddle, full desizing of the desizing liquid on the surface of the fabric is facilitated, through the front-back-side reciprocating motion of a stirring wheel, the stirring wheel drives the stirring paddle and bristles to movably clean the surface of the cloth, cleaning of the surfaces of the cloth with different widths is met, and the desizing efficiency of the cloth is greatly improved.

Description

technical field [0001] The invention relates to the technical field of cloth production, in particular to a descaling and bleaching one-bath system and method for short-process pretreatment of pure cotton woven cloth. Background technique [0002] Before weaving cotton fabrics, the warp yarns are generally subjected to sizing treatment. After the warp yarns are dipped in the sizing solution, they are then dried to make the fibers in the yarn stick together and form a thin film on the surface of the yarns to fit the warp yarns. Surface hairiness, and improve the wear resistance of the warp, easy warp weaving. Cotton fabric warps are generally sized with starch or modified starch sizing or mixed with polyvinyl alcohol and polyacrylic acid or polypropylene sizing, and additives such as lubricants, softeners, and preservatives are added to the sizing. However, the size on the cotton fabric will affect the hand feel and the normal progress of the subsequent printing and dyeing p...
