Description

A short-flow high-efficiency spinning machine for producing multi-component yarn

technical field

The invention relates to a short-flow high-efficiency spinning machine for producing multi-component yarns. The yarns spun by the spinning machine can be directly used for fabric weaving on shuttle looms and knitting machines, and belong to the technical field of textile processing.

Background technique

In recent years, blended products composed of multi-component raw materials have become very popular in the international market. The mixing of different raw materials (such as two-in-one, three-in-one) has expanded the use of textile materials and increased the style of such products. However, due to the large differences in the fineness, length and initial modulus of different raw materials, the difference in raw material performance will cause the problem of increased production difficulty when raw materials are mixed and woolen carding. For example, the rigidity of wool is relatively high, while the rigidity of viscose yarn and cashmere is small. When carding, the silk is easy to knot and form silk particles, which makes the appearance of the final fabric unsatisfactory.

In addition, the multi-component yarns used for autumn and winter clothing fabrics are generally composed of 3-4 single-ply yarn counts of 4 to 24. Its production process is raw material mixing, woolen carding, spinning, doubling, twisting, winding and twisting. The single-ply yarns that make up the strands are spun into rovings that have been processed through the slubbing and carding process by drafting, twisting, and winding on a spinning frame. The spun single-ply yarn was wound onto thick-walled plastic spinning tubes 180 mm in length and 21 mm in diameter. Under the limitation of the spinning principle and equipment of the spinning frame, the maximum yarn holding diameter of the spinning tube is only 45mm, and the yarn holding weight is about 150g. Due to the large diameter of this single-ply yarn, the output is very high. The small package of the spun bobbin results in frequent doffing and changing bobbins, high labor intensity, and a large turnover of spun yarn required; at the same time, due to the high spinning tension, it will also affect the steel ring and steel wire on the spinning frame. Machine parts such as rings have very serious wear and tear. At the same time, frequent tube changes also lead to an increase in the number of final yarn joints, which will also affect the appearance of the fabric.

The ratio of the opening width of the two arms of the flyer on the twisting and winding mechanism of the traditional suspended-spindle roving frame to the arm length of the flyer is usually 2:5. This size structure of the flyer makes the roving on the roving bobbin The maximum winding diameter is about φ150mm, and the maximum yarn capacity is about 2.5kg. The spun roving is further processed in the spinning process in the worsted processing system, and the process is relatively cumbersome.

Contents of the invention

The object of the present invention is to provide a kind of high-efficiency spinning machine with short process for producing multi-component yarn.

In order to achieve the above object, the present invention is achieved through the following technical solutions.

A short-process high-efficiency spinning machine for producing multi-component yarns. The surface of the third top roller of the drafting mechanism of the suspended roving frame is provided with a positioning annular groove along the circumference, and the upper pin and the lower pin are respectively fixed on the third roller. Between the third roller and the second roller, the upper apron is installed on the middle rubber rod and the upper pin, and the lower apron is installed on the third roller and the lower pin. There is a rear roller pair composed of the rear roller and the rear roller. The positioning yarn feeding device has a positioning yarn feeding hole corresponding to the positioning annular groove opened on the third top roller on the positioning yarn feeding device, and one or more than one yarn feeding holes are also opened on the positioning yarn feeding device. Yarn feeding hole and yarn feeding hole are on the same horizontal line. The ratio of the opening width of the two arms of the flyer on the twisting and winding mechanism of the spinning machine to the length of the arm of the flyer is 3:5.

When the positioning annular groove is opened on one side of the middle top roller, there is a positioning yarn feeding hole on the positioning yarn feeding device. on the side.

When the positioning annular groove is opened in the middle of the middle top roller, a positioning yarn feeding hole and two yarn feeding holes are opened on the positioning yarn feeding device. The yarn feeding holes are respectively located on both sides of the positioning yarn feeding holes.

When the positioning annular grooves on the middle top roller are double grooves, there are two positioning yarn feeding holes and one yarn feeding hole on the positioning yarn feeding device, and the axes of the two positioning yarn feeding holes are respectively aligned with the two positioning annular grooves. The central line of and is collinear, and the yarn feeding hole is located in the middle of the two positioning yarn feeding holes.

When the positioning annular grooves on the middle top roller are double grooves, there are two positioning yarn feeding holes and two positioning yarn feeding holes on the positioning yarn feeding device. The axes of the two positioning yarn feeding holes are respectively aligned with the two positioning ring The center lines of the slots are collinear, and the two yarn feeding holes are located in the middle of the two positioning yarn feeding holes.

Due to the adoption of the above-mentioned technical scheme, a short-process high-efficiency spinning machine for producing multi-component yarns of the present invention has positioning annular single grooves or double grooves at different positions along the circumference on the third top roller, and The third top roller and the upper pin are fitted with the upper apron, and the third roller and the lower pin are fitted with the lower apron. When the holding sockets formed by the third top roller and the third middle roller are squeezed by the upper apron and the lower apron on their surface to hold the roving strands passing through them, there is a positioning device on the third top roller. At the annular groove, the upper apron will move toward the positioning annular groove under the reaction force of the roving sliver. Therefore, the upper and lower aprons in this area have less grip on the fiber sliver and cannot firmly hold the fiber. The fibers within the strip can slide. The upper and lower aprons form a double apron slippery drafting area at the position where the positioning annular groove is opened. Whereas the positioning annular groove is not opened on the third top roller, the upper apron is in close contact with the third top roller, and the holding socket formed by the third top roller and the third roller can firmly hold the fiber through the upper and lower aprons, The fibers in the sliver cannot be drawn by sliding, and a double apron draft zone is formed in this area.

Under the guidance of the yarn feeding hole in the positioning hole, the fiber strands composed of short fibers whose quality length is greater than the center distance between the second roller and the third roller but smaller than the center distance between the third roller and the rear roller are fed into the double apron for slippery drafting During the zone, because the upper and lower aprons cannot firmly hold the fiber strands, the fiber strands are actually gripped by the second middle top roller and the second roller adjacent to the third top roller and the third roller. It is held separately by the holding socket formed by the rear top roller and the rear roller. Due to the large speed difference between the two pairs of rollers, the fiber strands are thinned to complete the drafting. In this case, the drafting distance of the fiber sliver is greater than the fiber quality length fed into the sliver by the positioning yarn feeding hole, thereby ensuring that the fiber with this quality length can be drafted smoothly without being broken.

Under the guidance of the yarn feeding hole, when the fiber strands composed of short fibers whose mass length is smaller than the center distance between the second roller and the third roller are simultaneously fed into the double apron drafting zone in parallel, the fiber strands are mainly drawn by the third apron. The gripping socket formed by the roller and the third roller (through the upper and lower aprons) is gripped respectively by the gripping socket formed by the second middle top roller and the second roller. Due to the large speed difference between the two pairs of rollers, the fiber strands are thinned to complete the drafting. In this case, the drafting distance of the fiber sliver is greater than the fiber quality length fed into the sliver by the yarn feeding hole, thereby ensuring that the corresponding fiber can be drafted smoothly without being broken.

In the above positioning drafting process, the drafting zone formed by the rear roller and the third roller is the tension drafting zone, and its main function is to tighten the fiber strands under a small tension. The speed of the rear roller and the third roller is basically The same (speed ratio is generally 1.02-1.05 times). Therefore, with respect to the second roller, the drafting ratios of the fiber strands with different quality lengths fed respectively by positioning the yarn feeding hole and the yarn feeding hole are the same.

The twisted winding process of a plurality of strands made of short fibers is as follows. The strands made of short fibers that have been drafted through the above partitions are output from the front roller, and then introduced into the false twister on the top of the flyer, and then pass through the hollow arm of the flyer, the yarn guide hole of the upper presser leaf of the L-shaped presser hand, Finally, it is wound on the roving bobbin that is loosely fitted on the bobbin disk. When the flyer rotates, the whiskers in the hollow arm only revolve around the roving bobbin, and do not rotate around its own axis, so it does not play the role of twisting, while the whiskers above the hollow arm to the false twister follow the flyer The rotation of the flyer rotates around its own axis, and a twist is added after the flyer rotates once to complete the twisting effect. The torque generated when this section of strand is twisted is transmitted upwards, so that the twist is distributed to a section of strand between the false twister and the front roller. The flyer rotates continuously, thus spinning a yarn with a certain twist and strength. The friction torque generated between the groove of the inner ring of the false twister and the axially moving sliver causes the sliver to rotate around its own axis at the edge of the top hole to generate false twist, which increases the twist of the sliver from the flyer to the front roller , to reduce the unexpected elongation of the roving, so that the short segment uniformity of the roving is improved. Since the twisting effect is applied to multiple strands of a single component composed of different fibers at the same time, the twisting process completes the combination of single yarns after spun yarn processing in the traditional spinning process and then twists them again. task. At the same time, since the twist coefficient is inversely proportional to the square root of the common count of the yarn, under the same twist condition, the twist coefficient of this multi-structure yarn is much higher than that of a single yarn with the same count. The higher twist coefficient ensures that the strength of this yarn is sufficient to meet the strength requirements of looms or knitting machines and clothes.

The rotating speed of the bobbin disk on the lower dragon rib is greater than the rotating speed of the flyer. Through the process calculation, the difference in rotating speed between the two satisfies the requirement that the linear speed at the guide hole on the pressing palm leaf on the surface of the roving bobbin is always equal to the delivery of the roller. speed. In this case, the above-mentioned finished twisted yarn is wound onto a roving bobbin which is looped onto a bobbin reel. During the winding process, since the weight of the pressing palm rod is slightly larger than that of the pressing palm leaf, the centrifugal moment of the pressing palm rod is always greater than that of the pressing palm leaf. Press on the yarn on the surface of the roving bobbin so that the yarn is tightly wound on the roving bobbin. During the winding process, the upper dragon shaft remains still, so that the position of the flyer fixed on the upper dragon shaft remains unchanged, and the lower dragon shaft makes up and down reciprocating movements with gradually decreasing strokes, so that the lower dragon shaft The upper roving bobbin also reciprocates upwards and downwards with a gradually reduced stroke. Under the guidance of the yarn guide hole of the pressing palm leaf on the flyer, the twisted yarn rotates in the axial direction of the roving bobbin in one circle. Arranged in a circle and wound layer by layer from the inside to the outside along the radial direction of the roving bobbin. As the height of the winding layers decreases layer by layer, the yarn finally wound onto the yarn bobbin forms a package form with truncated cones at both ends and a cylinder in the middle. This package form mainly prevents the yarn loops at both ends of the yarn on the roving bobbin from falling off. Since the yarn capacity of the roving bobbin is much higher than that of the spinning bobbin, the production efficiency of this large package is much higher than that of spinning on a spinning machine. However, in the winding process, when the length of the roving bobbin is constant, the thickness of the yarn wound on the roving bobbin determines the size of the yarn holding capacity. The thickness of the yarn is determined by the opening width of the flyer. In order to further increase the yarn holding capacity, the present invention adopts a flyer with a large opening width. The ratio of the opening width of the two arms of the traditional flyer to the arm length of the flyer is usually 2: 5, while the ratio of the opening width of the two arms of the flyer of the present invention to the length of the arm of the flyer is 3: 5, and the opening width The increase of the roving bobbin increases the yarn diameter from 152mm to 280mm, and the weight of the roving increases from 2.5kg to 4kg.

According to the positioning annular groove on the third top roller and the positioning yarn feeding hole and the yarn feeding hole on the positioning yarn feeding device, the present invention realizes simultaneous feeding of multiple roving strands of a single component composed of multi-component textile raw materials. Enter the spinning machine and carry out drafting, twisting, winding to form the specific form of the yarn.

1. When the positioning annular groove is opened on one side of the third top roller, there is a positioning yarn feeding hole on the positioning yarn feeding device. The axis of the positioning yarn feeding hole is collinear with the center line of the positioning annular groove. The side of the yarn hole. A sliver formed by a short fiber with a relatively long quality length is fed into the positioning yarn feeding hole; and another sliver formed by another short fiber with a relatively short quality length is fed into the yarn feeding hole. By adjusting the center distance between the back roller and the second roller, the distance value is suitable for the drafting of the sliver fed by the positioning yarn feeding hole, and by adjusting the center distance between the third roller and the second roller, the distance value is more than that set by Position the yarn feeding hole to feed the fiber quality length of the sliver to be 10mm-15mm larger. The drafting distance can meet the drafting requirements of two kinds of roving strands composed of two kinds of textile raw materials with different quality and length at the same time. After drafting, the sliver is introduced into the false twister, then passes through the hollow arm of the flyer, the yarn guide hole of the upper palm leaf of the L-shaped pressing hand, and finally winds on the roving bobbin that is loosely and tightly sleeved on the bobbin disk. After the above-mentioned twisting and winding of the spinning machine, the fiber strands form a yarn with a bicomponent structure on the roving bobbin. This method is mainly suitable for the spinning of two natural fibers with great differences in quality and length. This difference in length has made it impossible for the drafting mechanism of the traditional spinning machine to process the sliver of the blended roving composed of these two fibers. Complete normal drafting. Such as wool fiber roving strips and cashmere fiber roving strips, wool fiber roving strips and cotton fiber roving strips, etc.

2. When the positioning annular groove is opened in the middle of the third top roller, a positioning yarn feeding hole and two positioning yarn feeding holes are opened on the positioning yarn feeding device. The two yarn feeding holes are respectively located on both sides of the positioning yarn feeding hole. Feed a sliver made of a short fiber with a relatively long quality and length into the positioning yarn feeding hole. The types of fibers can be viscose, polyester, soybean fiber, water-soluble vinylon and nylon, tencel, modal, etc.; Feed another two roving slivers made of short fibers with relatively short quality and length into the yarn feeding hole. These two slivers are single-component roving slivers made of two different fibers with similar quality and length. The fibers used in one strand of the root are mainly natural fibers, including wool, cotton fiber, cashmere, hemp fiber, etc.; the fibers used in the other root are mainly viscose, polyester, soybean fiber, and water-soluble vinylon. And nylon, tencel, modal and so on. This choice of fiber varieties is because chemical fibers such as viscose, polyester, soybean fiber, water-soluble vinylon and nylon, tencel, and modal can be cut during the spinning process to obtain the length required for production, while natural fibers The length is not well controlled by artificial means. By adjusting the center distance between the back roller and the second roller, the distance value is suitable for the drafting of the sliver fed by the positioning yarn feeding hole, and by adjusting the center distance between the third roller and the second roller, the distance value is more than that set by Position the yarn feeding hole to feed the fiber quality length of the sliver to be 10mm-15mm larger. After drafting, the three strands are introduced into the false twister, and then pass through the hollow arm of the flyer, the yarn guide hole of the L-shaped pressing palm, and finally wound on the roving bobbin tightly sleeved on the bobbin disk . After the above-mentioned twisting and winding of the spinning machine, the fiber strands form a three-component yarn on the roving bobbin. This method is mainly suitable for spinning three-component yarns. The final spun yarn is characterized by fibers of relatively short mass length fed through the two yarn feed holes distributed over the surface of the yarn. Since natural fibers are distributed on the surface of the yarn, the spun yarn can take advantage of the properties of natural fibers, for example, natural fibers are very hygroscopic.

3. When the third top roller is provided with a positioning annular groove and is a double groove, there are two positioning yarn feeding holes and one yarn feeding hole on the positioning yarn feeding device. The axes of the two positioning yarn feeding holes are respectively aligned with the two positioning annular Groove and center line are collinear, and yarn feeding hole is positioned at the middle of two positioning yarn feeding holes. Feed two single-component strands composed of two chemical fibers with relatively long quality and similar length into the positioning yarn feeding hole. The types of fibers can be viscose, polyester, soybean fiber, water-soluble vinylon and nylon, Tencel, Modal, etc.; and feed another sliver made of short fibers with relatively short quality and length into the yarn feeding hole. The fiber types are mainly natural fibers, including wool, cotton fiber, cashmere, hemp fiber, etc. By adjusting the center distance between the back roller and the second roller, the distance value is suitable for the drafting of the sliver fed by the positioning yarn feeding hole, and by adjusting the center distance between the third roller and the second roller, the distance value is more than that set by Position the yarn feeding hole to feed the fiber quality length of the sliver to be 10mm-15mm larger. After drafting, the three strands are introduced into the false twister, and then pass through the hollow arm of the flyer, the yarn guide hole of the L-shaped pressing palm, and finally wound on the roving bobbin tightly sleeved on the bobbin disk . After the above-mentioned twisting and winding of the spinning machine, the fiber strands form a three-component yarn on the roving bobbin. This method is mainly suitable for spinning three-component yarns. The characteristic of the final spun yarn is that chemical fibers with relatively long mass length fed through two positioning yarn feeding holes are distributed on the surface of the yarn. This kind of yarn mainly utilizes the advantages of chemical fibers, such as high strength and good luster. The characteristics allow them to bear more tension during spinning, which can reduce end breaks during spinning. However, since natural fibers are mainly distributed in the interior of the yarn, its characteristics are difficult to express from the appearance. However, under normal circumstances, low-quality wool fibers can be placed inside the yarn, and the elasticity of the yarn can be increased by utilizing the good elasticity of wool.

4. When the third top roller is provided with a positioning ring groove and is a double groove, there are two positioning yarn feeding holes and two yarn feeding holes on the positioning yarn feeding device. The axes of the two positioning yarn feeding holes are respectively aligned with the positioning ring The center line of groove is collinear, and two two yarn feeding holes are positioned in the middle of positioning yarn feeding holes. Feed two single-component strands composed of two chemical fibers with relatively long quality and similar length into the positioning yarn feeding hole. The types of fibers can be viscose, polyester, soybean fiber, water-soluble vinylon and nylon, Tencel, Modal, hemp fiber, etc.; and feed the other two short fibers made of short fibers with relatively short quality and length into the yarn feeding hole. These two fibers are composed of two different fibers with similar quality and length. The single-component roving strands, the fibers used in one of the two strands are mainly natural fibers, including wool, cotton fiber, cashmere, hemp fiber, etc., and the fiber species used in the other of the two strands The main products are viscose, polyester, soybean fiber, water-soluble vinylon and nylon, tencel, modal, etc. By adjusting the center distance between the back roller and the second roller, the distance value is suitable for the drafting of the sliver fed by the positioning yarn feeding hole, and by adjusting the center distance between the third roller and the second roller, the distance value is more than that set by Position the yarn feeding hole to feed the fiber quality length of the sliver to be 10mm-15mm larger. After drafting, the four strands are introduced into the false twister, and then pass through the hollow arm of the flyer, the yarn guide hole of the upper palm leaf of the L-shaped pressing palm, and finally wound on the roving tightly sleeved on the bobbin disk. on the bobbin. After the above-mentioned twisting and winding of the spinning machine, the fiber strands form a four-component yarn on the roving bobbin. This method is mainly suitable for spinning four-component yarns. The characteristic of the final spun yarn is that the fibers in the four strands fed simultaneously through two yarn feeding holes and two positioning holes are distributed on the yarn. The probability of the surface is the same. This method is mainly suitable for producing multi-colored yarns according to fiber properties.

The spinning machine provided by the invention changes the drafting and winding mode of the traditional roving frame, and realizes that the single-component fiber strands composed of different textile raw materials can be fed into the drafting mechanism at the same time for drafting, twisting and winding , the resulting yarn is wound onto a roving bobbin with a large capacity. The yarn spun by this kind of spinning machine has a structure similar to strands and sufficient yarn strength to meet the requirements of looms or knitting machines, without the need for subsequent doubling, twisting, and winding processes, which is highly efficient The characteristics of the short process.

specific embodiment

Example 1

As shown in Fig. 2, a positioning annular groove 6 with a width of 12 mm and a depth of 3 mm is opened in the middle of one side of the third top roller 5 of the spinning machine, and a positioning yarn feeding hole with an aperture of 10 mm is opened on the positioning yarn feeding device 8 9 and an aperture are the yarn feeding hole 10 of 10mm, the positioning yarn feeding hole 9 and the yarn feeding hole 10 are on the same horizontal line. The axis of the positioning yarn feeding hole 9 is collinear with the center line of the positioning annular groove 6, and the yarn feeding hole 10 is positioned at the side of the positioning yarn feeding hole 9. Setting the center distance of the second roller 2' and the back roller 7' is 102mm, and setting the second roller 2' and the third roller 5' center distance is 45mm. Fix the flyer 13 on the upper dragon shaft 12 through the bearing, install a plurality of grooved annular false twisters 11 on the surface of the inner ring on the top hole of the flyer 13, and pass the L-shaped pressing hand 14 through the pressing hand on the pressing hand The upper and lower rings of the rod are looped on the hollow arms of the two arms of the flyer 13, and the hollow on the hollow arms runs through to the top hole of the flyer 13, and the presser palm 14 has a presser hand with yarn guide holes. leaf 15. Tighten the roving bobbin 16 on the bobbin disk 17 fixed on the lower dragon shaft 18 by the rotating shaft. The axis of rotation of the flyer 13 mounted on the upper dragon shaft 12 is collinear with the axis of rotation of the bobbin disc 17 mounted on the lower dragon shaft 18, and the upper dragon shaft 12 is parallel to the lower dragon shaft 18. The drafting ratio is set to be 10 times, the rotating speed of the flyer 13 is 1500r/min, the rotating speed of the front roller 1' is 160r/min, and the diameter of the front roller is 30mm, and the 15m/min of the delivery speed of the front roller 1' is calculated accordingly. min, the yarn holding capacity of the roving bobbin 16 is φ280×400mm, and the yarn winding starts from the lowermost end of the roving bobbin 16.

The above structure is suitable for spinning wool fiber and cotton fiber blended yarn.

Two wool staple fiber rovings and cotton staple fiber rovings (wherein the average length of the wool fiber is 77mm, and the quality length of the cotton fiber is 30mm) with two bar weights of 2.5g/m are introduced into the positioning feeding yarn of the yarn feeding device 8 respectively. Holes 9 and yarn feeding holes 10, wherein the wool roving sliver is introduced into the positioning yarn feeding hole 9, and the cotton roving sliver is introduced into the yarn feeding hole 10. Since the stretching distance is smaller than the quality length of wool at this time, in order to ensure that the wool fiber can slide freely in the slippery drafting zone, the depth of the positioning ring groove 6 is 1mm larger than the groove depth on the top roller in the traditional spun yarn. The groove depth on the top roller in traditional spinning is generally 2mm. The wool roving sliver respectively enters the back holding inset by the back top roller 7 and the back roller 7 ', the upper apron 4 fitted on the third top roller 5 and the upper pin 3 and the third roller 5 ' and The double-apron slippery drafting area formed by the lower apron 4' on the lower pin 3', the gripping socket formed by the second top roller 2 and the second roller 2', the front top roller 1 and the front roller 1' Front grip inset. Cotton fiber sliver enters respectively successively the back holding inset that is made of back top roller 7 and back roller 7 ', the upper apron 4 that is sleeved on the 3rd top roller 5 and the upper pin 3 and is sleeved on the 3rd roller 5 ' and The double apron drafting area formed by the lower apron 4' on the lower pin 3', the gripping socket formed by the second top roller 2 and the second roller 2', the front apron formed by the front roller 1 and the front roller 1' Hold the inset.

After the wool fiber strands and cotton fiber strands are positioned and drafted by the above partitions, they are introduced into the false twister 11 on the top of the flyer, and then are guided by the hollow arm of the flyer 13 and the pressure palm leaf 15 on the L-shaped pressure palm 14 in sequence. The yarn hole is finally wound on the roving bobbin 16 that is tightly sleeved on the bobbin disk 17 . When the flyer 13 was rotating at a rotating speed of 1500r/min, and the front roller 1' was rotating at a rotating speed of 160r/min, the twist that the fiber strands obtained was 10 twists/10cm. The friction torque generated between the groove of the inner ring of the false twister 11 and the axially moving wool fiber sliver and cotton fiber sliver promotes the sliver to rotate around its own axis at the edge of the top hole to generate false twist, so that the flyer 13 to The twist on a section of the sliver of the front roller 1 is increased to reduce the unintentional elongation of the sliver and improve the uniformity of the short section of the yarn. The finished twisted fiber strands form yarn. Through calculation, the rotating speed of the bobbin disk 17 is greater than the rotating speed of the flyer 13, and the twisted yarn can be wound onto the roving bobbin 16 on the bobbin disk 17. The rotational speed difference of the two should satisfy the linear velocity of the roving bobbin 16 surface at the guide hole place of the pressure palm leaf 15 and should always be equal to the delivery speed (15m/min) of the roller 1'. That is to ensure that the actual length of the front roller 1 ' output is equal to the winding length of the roving bobbin 16. During the winding process, the lower dragon tendon 18 is pressed so that the yarn can be spirally and tightly arranged on the roving bobbin and slowly descends, and the lower dragon tendon 18 is lowered to make the yarn guide hole of the pressing palm leaf 15 be located at the initial winding point of the roving bobbin 16. At 400mm, the lower dragon tendon 18 begins to slowly move upward again, and when the lower dragon tendon 18 rises to a distance of one yarn diameter away from the last maximum stroke, it starts to move upward at the above speed again; the lower dragon tendon 18 rises to When the yarn guide hole of the pressing palm leaf 15 is still one yarn diameter away from the highest end of the previous layer of yarn, the lower dragon tendon 18 begins to move slowly downward again, and the lower dragon tendon 18 moves in such a way that the amplitude decreases repeatedly. Finally, the yarn is formed on the roving bobbin 16 into a package in which both ends are truncated cones and the middle is a cylinder. The spun yarn count is 2 metric, the yarn capacity on the roving bobbin is φ280×400mm, and the yarn weight is about 4kg. The wool-cotton blended yarn has the characteristics of good elasticity of wool and good hygroscopicity of cotton.
