This invention discloses an antibacterial and antistatic cellulose blended yarn. The raw materials for preparing the blended yarn include natural fibers, deodorizing hemp pulp fibers, antistatic carbon fibers, mineral-modified fibers, and an antistatic agent. The raw materials, by weight, include the following components: 20-30 parts natural fibers, 10-12 parts deodorizing hemp pulp fibers, 10-20 parts antistatic carbon fibers, and 6-8 parts mineral-modified fibers. The natural fibers include bamboo fibers, cotton fibers, and hemp fibers, and possess inherent antibacterial components. The mineral-modified fiber raw materials are nano-zinc oxide and nano-titanium dioxide particles. The advantages of this invention compared to existing technologies are: the antibacterial and antistatic cellulose blended yarn of this invention has a soft and smooth hand feel and improved weaving performance; it retains the unique antibacterial and moisture-wicking functions of hemp fibers, while inheriting the comfortable and skin-friendly characteristics of cotton and viscose regenerated cellulose fibers; and it improves the antistatic performance of the blended yarn.

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.

This utility model relates to the technical field of fancy composite network yarn preparation equipment. A device for preparing high-cohesion, high-weaveability fancy composite network yarn includes a base plate, a winding mechanism on the top left side of the base plate, and a guide mechanism on the top right side of the base plate. An auxiliary mechanism is provided at the bottom of the base plate. The winding mechanism includes a connecting plate, a motor mounted on the top of the connecting plate, a third gear fixedly connected to the output end of the motor, a third connecting rod fixedly connected to the top of the third gear, and a support rod fixedly connected to the top of the third connecting rod. Through holes are provided at the top and bottom ends of both sides of the support rod, and telescopic rods are installed in each of the four through holes. A support plate is fixedly connected to the telescopic end of the telescopic rod, and a spring is provided on the outside of the telescopic rod. This utility model, through the telescopic rods and springs in the winding mechanism, enables the device to adapt to rolls of different sizes, improving the production efficiency of fancy composite network yarn.
