It is re-opened and combed into a single fiber state, and together with the Lenzing viscose fiber that has been opened and cleaned, it is uniformly fed and beaten to form a viscose roll, and then the viscose roll is carded, two-stage drawing, and roving in turn. , The environment-friendly pure spinning yarn is obtained after spinning.

Technical scheme: a production method of environmentally friendly pure spinning yarn, the method uses the suction flower collected in viscose fiber spinning and the remaining thick yarn through a mixed opener and a card needle opener in the opening and cleaning process. Re-opening and carding into a single fiber state, the optional Lenzing company's viscose fiber is subjected to cotton grabbing, metal spark two-in-one detector, impurity removal, mixed opening, card-type opening, and electrical distribution. Then, it is fed to the cotton feeder together with the viscose fiber that has been opened and combed into single fibers, and then outputted evenly by the single-hand roll forming machine. After drawing, roving and spinning, the environmentally friendly pure spinning yarn is obtained, which includes the following steps:

The first step: cotton blending: the selected viscose fibers include Lenzing viscose and viscose scraps as raw materials, of which Lenzing viscose accounts for 96.37%, and the average length is 37.8mm, with impurities/defects 1 %, fineness 1.28mm, elongation 23.76%, breaking strength 2.23cN/dtex viscose from Lenzing, viscose scraps including suction flower and slub, including 1.81% viscose spinning The suction flower collected in 1.82% viscose fiber spinning and the remaining thick spun yarn;

The second step: viscose scraps opening and cleaning treatment: the selected suction flower and thick spun yarn are sequentially grasped by the cotton picker according to the mixing ratio, and the mixed cotton opener realizes the grasped suction flower With the functions of opening, mixing and impurity removal of the coarse yarn, the cotton opener realizes the suction flower processed by the mixed opener and the opening, carding and impurity removal of the coarse yarn, so as to obtain the waste viscose fiber stream. A beater is arranged in the mixer opener. The beater is a cylindrical structure. The beater is driven by a motor to rotate. There are needle teeth evenly distributed on the outer circumference of the beater. At least one dust bar is arranged at the lower part of the beater. Keep the distance between the dust sticks, keep the distance between the beaters and the dust sticks, the viscose scraps that are caught are fed into the mixer opener through the pipeline device, and then brought into the beaters, and are driven by the rotation of the beaters. The bottom rotates along the beater, and the needle teeth on the beater surface hit the viscose fiber of the scrap during the rotation process, and in the process of the beater driving the scrap fiber to rotate, a negative force is formed between the beater and the dust rod. Pressure airflow area, so that the impurities in the fiber fall along the distance between the dust rods under the action of the negative pressure airflow in the negative pressure airflow area during the blowing process. The larger beater speed is adopted to realize the deep opening process under the heavy blow of the beater to the thick yarn, so as to open the incoming thick yarn into a fiber state. Therefore, it contains less impurities. Therefore, the distance between the dust rods is selected to enlarge the gap of the inlet part to facilitate the intake of air flow, and then the middle part is appropriately reduced, and the gap of the outlet part is large, so as to properly capture the wind and reduce the The loss of spinnable fibers; then the viscose leftovers processed by the mixed opener are fed into the card-type opener through the pipeline device. The card-type opener is provided with a beater, and the beater is a cylindrical structure. The beater is driven by the motor to rotate, and needle teeth are evenly distributed on the outer circumference of the beater. The upper part of the beater is provided with a cotton feeding roller, and the lower part is provided with at least one dust bar. Keep the distance between the dust sticks, keep the distance between the beater and the feeding roller, the viscose leftovers processed by the mixer opener are fed into the card-type opener through the pipeline device, and then driven by the feeding roller It is brought into the beater, and rotates along the beater driven by the rotation of the beater. During the rotation process, the needle teeth on the surface of the beater make a more in-depth free blow to the viscose fiber of the scraps located between the feed roller and the beater in a small area, and in the process of the beater driving the scrap fibers to rotate, in the process of the beater A negative pressure airflow area is formed between the dust rod and the dust rod, so that the impurities in the fiber fall along the distance between the dust rods under the action of the negative pressure airflow in the negative pressure airflow area during the striking process;
