Embodiment 1
[0031] A kind of production method of elastic denim fabric with low shrinkage rate, concrete steps are as follows:
[0032] (1) Spinning: The spinning process includes the cleaning process, carding process, drawing frame process, roving process, spinning process, and winding process;
[0033] (2) Dyeing: ASMA636-12 beam dyeing machine is used for warp dyeing production, and before beam dyeing, the yarn to be dyed is formed into a ball shaft using a HFGA136 cluster ball warp machine;
[0034] In the ball warp process, the speed of the ball warp is 200m / min, the dynamic tension of the single yarn is 20cN / thread, and the ball warp weave: 356 threads x 12 axes;
[0035] In the beam dyeing process, the warp yarn is scoured once at 80°C, washed once with hot water at 60°C, washed again with water at normal temperature, dyed with indigo at normal temperature for one pass, washed three times with water at normal temperature, and then washed with 60°C. ℃ softener, and finally dry it w...
