The invention discloses a dyeing process of tencel / flax blended yarn for light and thin denim fabric. The dyeing process comprises the steps of warp preparation and warp beam dyeing. Sequentially carrying out pre-wetting, multi-stage indigo dyeing, mild oxidation and alternate washing, post-treatment and drying; the warp beam dyeing is specifically as follows: warp yarns sequentially pass through a pre-wetting tank, at least four dyeing tanks, an oxidation zone, a rinsing tank and a post-treatment tank. By controlling the dyeing liquid to be alkalescent, low-temperature and low-tension technologies, chemical damage and physical stretching to tencel fibers are reduced, and fuzzing and broken ends are reduced. The pre-treated activated fiber and the gradient decreasing dye liquor concentration are matched with sufficient oxidation, the dye is promoted to diffuse into the fiber, the good dye penetration effect is achieved, the colored light is pure, and the color uniformity is guaranteed. And the weaving property of the yarn is improved through the post-treatment softening procedure. Due to hydrophilic softness and anti-wrinkle finishing, the yarn is soft and full in hand feeling and perfectly meets the comfort requirement of light and thin denim.

The application discloses a cutinase-amylase synergistic desizing process for sizing polyester fabric with starch and WPET mixed sizing material, and aims at the shortage of the traditional high-temperature strong-alkali desizing process, so that the sized polyester fabric is placed in the same desizing working solution, the synergistic effect of the cutinase and the amylase is utilized under the near-neutral and medium-temperature conditions, and the synchronous and efficient removal of the starch and the WPET mixed sizing material is completed in one step. The method has a simple process flow, can effectively remove the mixed sizing material, can significantly reduce the damage to the polyester fiber, can improve the fabric hand feeling, and has the outstanding environmental protection advantages of low energy consumption and small wastewater pollution load.
