Abstract

The invention discloses a pure cotton heavy fabric pretreatment method and belongs to the technical field of dyeing and finishing pre-treatment. The pure cotton heavy fabric pretreatment method comprises the steps of conducting corona discharge plasma treatment on a singed pure cotton heavy gray fabric, padding the fabric with scouring and bleaching liquid, then piling up the fabric at room temperature, executing steaming and washing, finally executing low-alkali mercerizing, and then executing full washing to complete the pure cotton heavy fabric pre-treatment process. The process is good intreatment effect, has the advantages of small fabric strength damage, high quality, soft handfeel, high hair effect and good glossiness, also creates the high color yield condition for subsequent dyeing and printing processing and is simple in technological operation and strong in controllability. In addition, the treatment wastewater, chemical agent use amount and energy consumption of the process are far lower than those of a traditional strong alkali scouring process, is a clean production process meeting the environmental protection requirements, greatly reduces the burden of sewage treatment of enterprises is greatly reduced and has very high social benefits and market prospects, and the process conditions are optimized.

Description

【Technical field】 [0001] The invention relates to a pretreatment method of pure cotton heavy fabric. 【Background technique】 [0002] Pure cotton heavy dyed fabrics are mostly used as high-end decorative fabrics, clothing fabrics and tourism product fabrics, etc. It is one of the fashion materials with market competitiveness and is favored by consumers. However, due to its organizational structure, pure cotton heavy fabrics contain high impurities, and require high pre-treatment processes such as desizing and scouring, which must be strictly controlled to meet the application requirements. [0003] At present, the pretreatment of heavy pure cotton fabrics generally uses a three-step process, that is, desizing, scouring and then bleaching, or a two-step process, that is, desizing and scouring, and then bleaching. Due to the special organizational structure of thick pure cotton fabrics, if a large amount of impurities such as cotton seed shells mixed in the fabric core structu...
