Embodiment 1

[0035] The production method of cotton-polyester interwoven spandex core-spun elastic fabric, including cotton, polyester and spandex, has 16 counts of cotton in the warp direction, and 150D low-elastic network yarn and 70D spandex covering yarn in the weft direction. The dyeing process includes steps in turn: turning Cloth, deboiling, singeing on one side, oxygen bleaching, setting, mercerizing, pad dyeing and double dyeing of the same color, finishing;

[0036] The front and back of the cloth are required to be consistent, the seam head is straight, and it is required to be flat, straight, neat, and firm. The stitch density is 40-45 stitches / 15cm, and the two sides are denser to 4-6 stitches / cm, so as to prevent wrinkles and wrinkles in the printing and dyeing process. Weft oblique, curling.

[0037] The single-side singeing process is specifically gas singeing, singeing twice on the front side of the two burners, and the speed is 82m / min.

Abstract

The invention relates to a production method of textiles, in particular a production method of cotton polyester interwoven spandex core-spun elastic fabric. The cotton polyester interwoven spandex core-spun elastic fabric comprises cotton, polyester and spandex. Sixteen threads of cotton are woven in the warp direction, and 150D low-elasticity interlaced yarn and 70D spandex coated yarn are woven in the weft direction. The dyeing process of the cotton polyester interwoven spandex core-spun elastic fabric sequentially includes the steps of fabric turnover, scouring retreating, single-surface singeing, oxygen bleaching, shaping, mercerizing, double dyeing of pad dyeing and dyeing in the same color and finishing. A scouring and bleaching combined production line is adopted in the steps of scouring retreating and oxygen bleaching, the fabric is subjected to six-latticed countercurrent flattening washing prior to rolling pressure so as to control the moisture content to be 45-55% and subjected to padding in oxygen-bleaching liquid for fabric bleaching; the dyeing process further includes dipping flame-retardant treatment after the finishing process, namely putting the fabric into a vacuum pressure tank to be vacuumized and enabling vacuum degree of the vacuum pressure tank to be from -0.015MPa to -0.025Mpa, and adding a fire retardant into the tank and enabling the pressure to be increased to from 0.1MPa to 0.8Mpa. The fabric is stable in size after being washed, needless of ironing and energy saving in production, and flame-retardant safety is achieved.

Description

technical field [0001] The invention relates to a production method of textiles, in particular to a production method of cotton-polyester interwoven spandex core-spun elastic fabric. Background technique [0002] The application of elastic fabrics on clothing provides comfort, casualness and aesthetics showing the shape of the human body, and is deeply loved by consumers. CN102995199A (2013-3-27) discloses a processing method of two-component elastic spandex core-spun yarn, but the yarn prepared by this method does not meet the needs of some consumers, the size is unstable after washing, and it is easy to wrinkle. Frequent ironing will affect the aesthetics and practicality, and the production process consumes a lot of energy, and the product does not have a flame-retardant effect. Contents of the invention [0003] The object of the present invention is to provide a production method of cotton-polyester interwoven spandex core-spun elastic fabric which is stable in size ...
