Embodiment 1

[0015] A dyeing process of hemp gray fabric, comprising the following steps: turning cloth → seaming → singeing → cold stacking → pouring water → mercerizing and rolling → dyeing → softening large scrolls → grasping → shearing → shaping → pre-shrinking → finished product → check and roll; wherein, the weft yarn of the gray cloth adopted is the yarn count of CVC10, and the composition is 70% cotton and 30% polyester, and the weft yarn is the yarn count of 16+70D, and the gray cloth is The weft density is 78w, and the door width is 150cm.

[0016] In the seam process, a three-thread seam process is used. During the singeing process, the vehicle speed was 110 m / min, the flame was 12 mbar, the enzyme rolling temperature was 70° C., and the stacking time was 3 hours. During the shaping process, the vehicle speed is 45 m / min, and the air volume is 1500 r / min. During the pre-shrinking process, the vehicle speed is 35 m / min, and the rubber blanket pressure is 25 MPa.

Abstract

The invention discloses a heather grey cloth dyeing technology, and the technology comprise the following steps: cloth turning, sewing, singeing, cold stacking, washing, mercerizing and coiling, dyeing, softening of a big reel, ball wool opening, cutting, sizing, pre-shrinking, forming of a finished product, and verification and coiling. Weft yarn of employed gray fabric is CVC yarn count, and is made of 70% of cotton and 30% of polyester, and is 16+70D yarn count. Through the selection of special gray fabric and the cooperation with the corresponding dyeing technology, the visual effect of the heather grey of the finished product is enabled to be better, and a shell fabric is thick and warm.

Description

technical field [0001] The invention relates to a dyeing process of hemp ash cloth, which belongs to the technical field of textile printing and dyeing. Background technique [0002] Hemp gray fabric is favored by consumers because of its special color and texture, but after the existing dyeing process, hemp gray fabric has the problems of poor color fastness, poor abrasion resistance and high shrinkage.
