Pure cotton warp yarn foam printing and weaving method

Abstract

The invention discloses a pure cotton warp yarn foam printing and weaving method. The printing and weaving method contains no sizing process, and concretely comprises the following steps: pure cottonraw yarn preparation, beam warping, beaming, foam coating printing, weaving, and grey cloth shaping for obtaining a finished product, wherein the foam coating printing process comprises: foam generation using a foam generator, foam coating color paste preparation, foam coating spraying and color fixing. A printing and weaving technology for sizing-free weaving after foam printing of warp yarns isused to directly perform large-area blotch printing on sheet-like warp yarns unwound from a plurality of warp shafts on the shaft bracket of a warp sizing machine, and a weave beam is produced after color fixing without sizing. The weave beam and weft yarns are woven on a loom to form a fabric, so the water washing process after desizing is omitted, the water consumption is saved, and the wastewater treatment difficulty is reduced, so the method is clean production technology. The method has the advantages of flow shortening, energy consumption reduction and cost reduction.

Description

technical field [0001] The invention belongs to the field of textile weaving and printing processing, and in particular relates to a pure cotton warp yarn foam printing and weaving method. Background technique [0002] With the deteriorating global environment, green environmental protection and clean production are the long-term development of the country and the direction of industrialization that people expect. The production of conventional printed textiles requires desizing and printing after sizing and weaving. It requires multiple processing procedures, which not only consumes high energy, but also requires a lot of washing. Moreover, the conventional pigment printing process needs to consume a lot of water in the preparation of color paste, and also consumes a lot of energy in the drying process because of the high water content in the printing part, which is not good for energy saving and environmental protection. [0003] The invention proposes a foam printing and...
