Production process of flat twill gray fabric

The invention discloses a production process of flat twill gray fabric. Gloss flat FDY filaments and semi-gloss round hole DTY filaments are selected for surface yarns, and the ratio of the gloss flatFDY filaments to the semi-gloss round hole DTY filaments is 1: 1; semi-gloss round hole FDY filaments are selected for bottom yarns; the mass percentage of the surface yarns is 60 percent, and that of the bottom yarns is 40 percent; the surface yarns and the bottom yarns are respectively wound on pan heads after being warped by a warping machine, and then the pan heads are mounted on a warp beamof a warp knitting machine in a proportion and woven into the gray fabric. The gray fabric produced by the production process of the flat twill gray fabric is good in softness, and the application range is expanded. 本发明公开了一种扁平斜纹坯布的生产工艺，面纱选用有光扁平FDY丝和半光圆孔DTY丝，两者比例为1:1，底纱选用半光圆孔FDY丝，面纱质量百分比为60％，底纱为40％，面纱和底纱分别经整经机整经处理后卷绕在盘头上，然后将盘头按比例安装到经编机经轴上织造成坯布。该扁平斜纹坯布的生产工艺生产的坯布柔软性好，扩展了应用范围。
