The invention provides a yarn guide device for a two-for-one twister, which solves the problem that the tension of the existing yarn guide device cannot be adjusted, and the textile yarn is prone to splitting and end breakage, which seriously affects the work quality; The adjustment component drives the position of the yarn guide component to be adjusted in the X-axis and Z-axis directions. The adjustment is simple and convenient, so that the textile thread is in a tensioned state and avoids the splitting of the textile thread; the drive rod is pushed by the cylinder to move in the X-axis direction, and the drive plate follows the direction of the X-axis. The drive rod moves in the X-axis direction, the transmission block A cooperates with the drive groove, and the transmission rod moves in the Z-axis direction to complete the adjustment of the position of the yarn guide assembly in the Z-axis direction; the motor drives the main shaft to rotate, the pulley rotates with the main shaft, and the cable and Friction is generated between the pulleys to move the cable to complete the adjustment of the yarn guide assembly in the X-axis direction; the product quality is improved through the yarn guide assembly, and the spring is used as a buffer to reduce tension fluctuations and reduce the phenomenon of textile thread breakage.

Disclosed is an apparatus for drawing and winding POY filament yarn. The drawing and winding apparatus comprises: a yarn cutting and suctioning apparatus, a pre-interlacing device, a first yarn guide plate, a second yarn guide plate, a lifting mechanism, a lifting seat, a machine frame and a winder, wherein the yarn cutting and suctioning apparatus, the pre-interlacing device and the first yarn guide plate are provided in succession on one side of the machine frame based on the direction of travel of a tow; the lifting mechanism is provided on the machine frame, the lifting seat is linked to the lifting mechanism, and the lifting seat makes a reciprocal movement in a vertical direction under the drive of the lifting mechanism; the second yarn guide plates are two in number and are provided horizontally on the lifting seat; the winder is provided below the second yarn guide plates; after passing through the yarn cutting and suctioning apparatus, the pre-interlacing device and the first yarn guide plate, the tow is divided into two bundles respectively reeled on the two second yarn guide plates and then entering the winder to be wound. The present invention simplifies the structure and also increases the quality of the yarn, and enables more spinning station equipment to be installed in the same factory, increasing production capacity and reducing engineering construction costs.

The invention relates to a preparation method of calotropis gigantean fiber pure spinning blended yarn. Through strip forming, drawing, rough yarn and fine yarn processes of calotropis gigantean fiber, the calotropis gigantean fiber pure spinning blended yarn is prepared. Strip forming is conducted in the mode that the calotropis gigantean fiber is combed by metal card clothing on the surfaces ofa feeding stabbing roller and an opening roller, is divided into a single-fiber state, is transmitted and enters a strip forming cylinder which rotates under the effect of negative pressure airflow which is generated by an exhaust fan, is parallelly arrayed along the inner side of the cylinder wall of the strip forming cylinder in the circumferential direction, and slides into a strip forming groove and is stacked into annular fiber strands under the effect of centrifugal force; the strip forming cylinder is a rotation body and is composed of a cylinder body and a cylinder shaft, an opening isformed in one end of the cylinder body, and the cylinder body is composed of a cylinder bottom, a cylinder wall and the strip forming groove which makes the cylinder bottom connected with the cylinder wall; the diameter of the cylinder body is gradually increased from the cylinder opening to the strip forming groove, and the cylinder shaft is located on the outer side of the cylinder body and isvertically connected with the center of the cylinder bottom. According to the preparation method, strip forming is successfully conducted under the situation that the fiber is less damaged, and the prepared calotropis gigantean fiber is low in short fiber content and high in quality.

The invention provides a pearl fiber blended yarn, which is prepared from 35 to 45 percent of tencel, 35 to 45 percent of modal fiber and 15 to 25 percent of pearl fiber by weight percentage through blended spinning. The invention also provides a slippery ventilated comfortable sweater woven from the pearl fiber blended yarn and a method for producing the same. The sweater or an underwear productalso has the characteristics of the tencel, the modal fiber and the pearl fiber, is slippery and soft in hand feeling and ventilated, has good hygroscopicity, is not toxic and irritative to a human body, and can make pearl particles give play to functions of caring skin, beautifying, clearing fever and whitening after contacting with skin for a long time. The calcium carbonate content in the pearl fiber blended yarn has far infrared emission function and ultraviolet resistant function, and can not only accelerate human body microcirculation and promote metabolism, but also prevent skins from being hurt by ultraviolet, thus the pearl fiber blended yarn has certain health care and protective effects on the human body.

The invention discloses a method for spinning combed noil yarn by rotor spinning. Combed noil yarn is produced by spinning technology. The spinning technology comprises following steps: raw material matching process, cotton opening and picking process, combing process, drawing process and rotor yarning forming process; Through the adjustment of technological parameters of rotor spinning technology and improvement of technical members, by means of the rotor spinning method of the invention, yarn production efficiency and rotor spun yarn strength are increased, and the broken ends during rotor spinning are effectively reduced. The rotor spinning method has good effect on rotor spinning combed noil yarn under 14.7tex; the method can help enterprises upgrade industry and save cost.
