Manufacturing process of polyester cotton yarn-dyed fabric

Abstract

The invention discloses a manufacturing process of a polyester cotton yarn-dyed fabric. The manufacturing process comprises the following technological steps: selecting a polyester cotton blended yarn; sequentially performing scouring, blanching, dyeing, soap-boiling, water washing and drying, wherein beam dyeing is adopted, and in the dyeing process, the winding density of a warp of a warping machine is 0.46-0.48 g/cm<3>; before dyeing, adding 0.2-0.4 g/L sodium sulfate into water required by dyeing, performing stirring for 8-10 min; adding sodium carbonate first at the water temperature of 35-40 DEG C; after 12-15 min, adding sodium sulfate for 12-15 min; and maintaining for 42-46 min when the temperature rises to 62 DEG C. According to the manufacturing process, the dyeing effect is improved, more uniform dyeing is achieved, the dyeing freshness is guaranteed, the static property of a spun polyester thread is reduced by an anti-static agent, the static ratio of the polyester cottonyarn-dyed fabric which is woven is favorably reduced on the whole, in addition, triple-jump, yarn breakage and yarn sinking are reduced, and the sizing percentage is increased.

Description

technical field [0001] The invention belongs to the technical field of textiles, in particular to a production process of polyester-cotton yarn-dyed fabric. Background technique [0002] Yarn-dyed fabric is a fabric made of dyed yarn. Yarn dyeing is generally divided into two ways: yarn-dyed yarn and dyed yarn. Usually, yarn-dyed fabric refers to the fabric woven by shuttle looms, but the same is true for knitting machines. Yarn-dyed knitted fabrics can be made. According to different raw materials, yarn-dyed fabrics can be divided into yarn-dyed cotton, yarn-dyed polyester-cotton, yarn-dyed mid-length wool-like tweed, all-wool tweed, wool-polyester tweed, and wool-polyester-viscos three-in-one tweed , slub gauze, pimple gauze, etc., and there are many yarn-dyed fabrics with silk and linen as raw materials; polyester-cotton yarn-dyed fabrics use polyester as raw materials, polyester is prone to static electricity, so for the finished polyester-cotton yarn-dyed fabrics It is...

[0002] Yarn-dyed fabric is a fabric made of dyed yarn. Yarn dyeing is generally divided into two ways: yarn-dyed yarn and dyed yarn. Usually, yarn-dyed fabric refers to the fabric woven by shuttle looms, but the same is true for knitting machines. Yarn-dyed knitted fabrics can be made. According to different raw materials, yarn-dyed fabrics can be divided into yarn-dyed cotton, yarn-dyed polyester-cotton, yarn-dyed mid-length wool-like tweed, all-wool tweed, wool-polyester tweed, and wool-polyester-viscos three-in-one tweed , slub gauze, pimple gauze, etc., and there are many yarn-dyed fabrics with silk and linen as raw materials; polyester-cotton yarn-dyed fabrics use polyester as raw materials, polyester is prone to static electricity, so for the finished polyester-cotton yarn-dyed fabrics It is inevitable that static electricity will be generated. In addition, dyeing is especially important in the weaving process of yarn-dyed fabrics. However, at present, uneven dyeing will occur in the dyeing process, and the dyeing effect is not ideal. In view of this, it is necessary to Improve the production process of fabrics
