Description

Technical Field

[0001] This invention relates to the field of new textile technology, and in particular to a method for producing antibacterial glossy fabrics. Background Technology

[0002] Generally, yarns with a twist coefficient exceeding 700 or a twist greater than 1800 twists / m are called super-twist yarns. These yarns have a more distinctive fabric style, and with the tight spinning method, the fabric surface will also exhibit a unique "water ripple" effect. High-twist products are mostly produced by some companies using polyester fibers, while a few companies use viscose raw materials, but the twist is generally within 1650 twists / m.

[0003] In addition to its excellent properties, bamboo fiber has the lowest single fiber strength among many fiber types, at only about 2.4 cN / dtex. The most serious problem is that its wet strength is only 50% of its dry strength, at only about 1.2 cN / dtex. This is a bottleneck restricting the production and application of high-count bamboo pulp fiber yarn, especially when producing pure spun yarn with a count of 9.84 tex or higher.

[0004] The production difficulty of high-twist yarn is higher than that of conventional twist yarn. Because the twist coefficient exceeds the critical value, its strength is relatively low. The yarn properties are not advantageous compared with ordinary twist yarn of the same count. Moreover, an additional steaming process is required, and precise steaming process parameters must be optimized. At the same time, under the same conditions, the self-winding process is prone to yarn slippage and defective bobbins. The twisting problem is the core difficulty. Due to the large twist coefficient, untwisting is insufficient or even impossible. This difficulty increases when the twist exceeds 1650 twists / m, and the difficulty doubles when the twist is >2000 twists / m. In addition, high-twist yarn requires a steaming process to fix the twist, but the wet strength of bamboo pulp fiber is only 50% of the dry strength, which further highlights the already low strength of the yarn.

[0005] In the spinning process, drafting is one of the most crucial steps. During drafting, the relatively coarse fiber bundle fed in changes speed between nipples with a certain speed difference, causing the fibers to slip against each other and thus achieving the transition from coarse to fine. A typical spinning machine uses two drafting zones. The rear drafting zone, located at the back, has a smaller drafting ratio and therefore generally employs a simple roller drafting structure, primarily handling the fed fiber bundle under small drafting conditions. The front drafting zone, located at the front, has a larger drafting ratio and undertakes the main drafting and thinning effect on the fiber bundle. To achieve more uniform drafting, the front drafting zone typically uses an apron structure. The apron nipples, composed of upper and lower aprons, provide stable control over the fibers within the bundle, achieving stable and concentrated fiber speed changes under large drafting conditions. Therefore, the apron is one of the most important drafting elements in the spinning drafting zone.

[0006] During the yarn drafting process, the upper apron is directly fitted onto the upper pin. The upper pin, with its elastic structure, provides adaptive tension control for the upper apron. After being fitted, the upper apron rotates due to the corresponding upper roller. The lower apron is fitted onto the lower pin. To achieve adaptive tension control for the lower apron, it is fitted onto the apron tension frame. The elasticity of the tension frame provides adaptive tension for the lower apron, which then rotates due to the corresponding lower roller. However, during contact with the lower apron, the tension frame generates frictional resistance, hindering its rotation and affecting the synchronization between the lower apron and the lower roller, thus impacting drafting efficiency, especially for high-twist yarns. Summary of the Invention

[0007] The purpose of this invention is to provide a method for producing antibacterial glossy fabrics. Fine denier bamboo pulp fibers are selected, and a suspended lower carding roller with a carding cloth is installed between the drafting system of the first and second drawing stages and the output trumpet. This straightens the front and rear hooks of the fibers in the bamboo pulp sliver. In the spinning process, a tension frame with tension pins arranged in a staggered pattern on two sides of the support end that contacts the lower apron reduces the frictional resistance of the support end to the lower apron, achieving efficient drafting of the high-strength bamboo pulp roving, improving yarn strength, reducing yarn breakage, and thus achieving the production of high-quality bamboo pulp yarn with a high twist coefficient, thereby producing antibacterial glossy fabrics.

[0008] This invention provides a method for producing an antibacterial glossy fabric, comprising the following steps: Fine denier bamboo pulp fiber of 1.11dtex×38mm is selected and processed sequentially through an automatic cotton grabbing system, a multi-compartment cotton blending system, a carding needle and beater opening system with a cotton coagulator, a vibrating cotton feeding system, a cotton cleaning and smoothing system including a balance adjustment device and a beater opening device, and a carding system with a cotton box to produce fine denier bamboo pulp sliver. Fine denier bamboo pulp sliver is obtained through three drawing processes. A suspended lower combing roller with carding cloth is set between the drafting system of the first and second drawing processes and the output trumpet, so as to straighten and straighten the front and rear hooks of the fibers in the bamboo pulp sliver. Fine denier bamboo pulp roving is produced by a small draft of less than 10 times and a twist coefficient of less than 120. Then, fine denier bamboo pulp high twist yarn is produced by a large draft of more than 30 times and a twist coefficient of more than 700 through ring spinning. In a spinning frame, a fixed lower pin is set on the lower drafting roller of the drafting roller pair, and a lower long leather ring is fitted on it. The lower part of the lower long leather ring is supported by the leather ring tension frame. An upper short leather ring is fitted on the upper drafting roller through an elastic upper pin. The apron tension frame consists of a tension frame and an elastic fixing device, which are composed of an installation end, a connector, and a support end. The two sides of the support end that contact the lower apron are provided with staggered tension pins to reduce the frictional resistance to the lower short apron and achieve efficient drafting of bamboo pulp roving with high fiber straightness. Part of the fine denier bamboo pulp high twist yarn is wound, warped, and sized to obtain warp yarn, and part of it is steamed and twisted once, wound, and steamed and twisted twice to obtain weft yarn. After weaving, an antibacterial glossy fabric is obtained. In the weaving process, the weft yarn adopts a combination of two weft Z twist yarn and two weft S twist yarn in an alternating cycle, and the weft tightness is set to be greater than the warp tightness.

[0009] In the production method of the antibacterial glossy fabric described above, preferably, the selected fine denier bamboo pulp fibers are laid in the disc of an automatic cotton grabber, and are grabbed by negative pressure adsorption after the fibers on the surface of the laid fine denier bamboo pulp fiber layer are struck by the cotton grabber beater. The fine denier bamboo pulp fibers are grasped and mixed in large capacity under the input-output time difference or the input-output path difference through 8-10 high cotton bins of the multi-bin cotton blender; The mixed fine denier bamboo pulp fibers are opened by a carding and beating machine, and the exposed impurities are separated and discharged during the opening process. After being opened, the fine denier bamboo pulp fiber is vibrated and fed to the cotton to make the fine denier bamboo pulp fiber flow uniform and then continuously conveyed to the cotton cleaning and leveling machine in front. The cotton cleaning and leveling machine adopts the balance adjustment device and the beater opening device in the single beater lap machine. After processing, the fine denier bamboo pulp fiber flow is uniformly processed under the input control of the balance adjustment device of the cotton cleaning and leveling machine to achieve uniform delivery of the fine denier bamboo pulp fiber flow. Then, it is opened by the beater opening device under free impact, which further reduces the bonding force between the fibers in the uniformly delivered fine denier bamboo pulp fiber flow. The fine denier bamboo pulp fiber stream is fed into the cotton box of the carding machine in a uniform fiber bundle state. Fine denier bamboo pulp fiber bundles are processed by the licker-in rollers of a carding machine to hold and strike the fibers, then by the cylinder-flat carding process, followed by the transfer and cohesion of the fibers by the doffer to form a web, and finally by the gathering of the fibers at the bell mouth to form a sliver, thus producing fine denier bamboo pulp sliver.

[0010] In the production method of the antibacterial glossy fabric described above, preferably, in the first drawing process, six fine denier bamboo pulp slivers are fed together. These six slivers are then gathered and entered into the drafting system. After a large back zone drafting action of 1.7 times or more, the fiber hooks within the sliver are straightened. Following the front zone drafting, a fine denier bamboo pulp sliver with the desired linear density is obtained. A suspended lower carding roller with straightening card cloth is installed at the front of the drafting system, and a lower carding roller is also provided. The linear speed of the roller is 1.05-1.1 times the speed output by the drafting system of the fine denier bamboo pulp sliver. This creates a speed difference between the straightening needle cloth and the fine denier bamboo pulp sliver. Under the action of the speed difference, the front hooks of the fibers in the fine denier bamboo pulp sliver, that is, the rear hooks of the fibers in the fine denier bamboo pulp sliver, are straightened. After being gathered through the bell mouth, they enter between the output pressure rollers. After being pressed and processed by the output pressure rollers, the fine denier bamboo pulp sliver is obtained and continuously coiled in the sliver can.

[0011] In the production method of the antibacterial glossy fabric described above, preferably, in the second drawing process, six fine denier bamboo pulp slivers are fed together. These six slivers are then gathered and entered into the drafting system. After a moderate back zone drafting action of 1.4-1.6 times, the fiber curvature within the sliver is straightened. Following a front zone drafting, the desired fine denier bamboo pulp sliver linear density is obtained. A suspended lower carding roller with a straightening card cloth is installed at the front of the drafting system, and... The rotational linear speed of the lower combing roller is 1.01-1.05 times the speed output by the drafting system of the fine denier bamboo pulp sliver. This creates a speed difference between the straightening card cloth and the fine denier bamboo pulp sliver. Under the action of the speed difference, the front hooks of the fibers in the fine denier bamboo pulp sliver, that is, the front hooks of the fibers in the fine denier bamboo pulp raw sliver, are straightened. After being gathered through the bell mouth, they enter between the output pressure rollers. After being pressed and processed by the output pressure rollers, the fine denier bamboo pulp semi-cooked sliver is obtained and continuously coiled in the sliver can.

[0012] In the production method of the antibacterial glossy fabric described above, preferably, in the three drawing stages, six fine denier bamboo pulp semi-cooked slivers are fed together. After the six fine denier bamboo pulp semi-cooked slivers are gathered and combined, they enter the drafting system. After a small back zone drafting action of up to 1.4 times, the fiber distribution within the semi-cooked sliver is uniformly arranged. After a front zone drafting, the fine denier bamboo pulp sliver with the required linear density is obtained. After being gathered through the trumpet mouth, it enters between the output pressure rollers. After being pressed and arranged by the output pressure rollers, the fine denier bamboo pulp cooked sliver is obtained and continuously coiled in the sliver can.

[0013] In the production method of the antibacterial glossy fabric described above, preferably, the mounting end includes a nesting tube, which is a hollow and closed cylindrical structure made of nylon. A left embedding hole is opened on the left end circular surface of the nesting tube. The center of the left embedding hole is consistent with the center of the left end circular surface of the nesting tube. A right embedding hole is opened on the right end circular surface of the nesting tube. The center of the right embedding hole is consistent with the center of the right end circular surface of the nesting tube. The left embedding hole and the right embedding hole are exactly the same. A spring insert is opened along the axial direction of the side of the nesting tube. The spring insert is an arc-shaped structure. The length direction of the spring insert is consistent with the length direction of the nesting tube. The curvature of the spring insert is between 1 / 5 and 1 / 4 of the circumference. A connecting piece is provided on the outer side of the nesting tube adjacent to the spring insert. The connecting piece is a cuboid structure. One side of the connecting piece is integrally fixedly connected to the outer side of the nesting tube. The connecting piece is made of nylon.

[0014] In the production method of the antibacterial glossy fabric described above, preferably, a connector is provided at the front of the mounting end. The connector includes a rear fixing member and a front connecting member. The connector is made of nylon. The rear fixing member is a right triangular prism structure with a right-angled triangle base. One side of the rear fixing member is fixedly connected to the connecting piece, so that the side edges where the other two sides of the rear fixing member are connected face forward, forming the forward connecting edge of the rear fixing member. The right-angled edge of the bottom surface of the rear fixing member is vertically aligned with the right-end circular surface of the nesting cylinder. The front connecting member is a cuboid structure. The rear side of the front connecting member is fixedly connected to the forward connecting edge of the rear fixing member, so that the right side of the front connecting member is vertically aligned with the right-end circular surface of the nesting cylinder.

[0015] In the production method of the antibacterial glossy fabric described above, preferably, a support end is provided on the left side of the front connector. The support end is made of nylon and has a cuboid structure. The right side of the support end is fixedly connected to the left side of the front connector. After connection, the lower side of the support end and the lower side of the front connector are horizontally aligned. The length direction of the support end is consistent with the length direction of the nested tube. The left side of the support end and the left end circular surface of the nested tube are vertically aligned. The height of the support end is less than the width of the front connector, so that the part of the front connector located between the upper side of the support end and the upper side of the front connector constitutes a right baffle. A left baffle is provided on the left side of the support end. The left baffle is made of nylon and has a cuboid structure. The width of the left baffle is consistent with the width of the support end. The right side of the left baffle is fixedly connected to the left side of the support end. After connection, the upper side of the left baffle and the upper side of the right baffle are horizontally aligned. Pretensioning pins, made of nylon and solid semi-cylindrical in shape, are evenly spaced along the front edge of the upper side of the support end. The rectangular base of each pretensioning pin is fixedly connected to the upper side of the support end, and the front edge of the rectangular base of the pretensioning pin is vertically aligned with the front edge of the upper side of the support end. The distance between two adjacent pretensioning pins is equal to the length of the pretensioning pin. The leftmost pretensioning pin is vertically aligned with the left side of the support end, and the distance between the rightmost pretensioning pin and the right side of the support end is equal to the length of the pretensioning pin. Along the rear side of the upper side of the support end… The side is provided with equally spaced back tension pins. The back tension pins are identical in structure and material to the front tension pins. The rectangular bottom surface of the back tension pin is fixedly connected to the upper side surface of the support end. After connection, the front side of the rectangular bottom surface of the back tension pin is vertically aligned with the rear side of the upper side surface of the support end. The distance between two adjacent back tension pins is equal to the length of the back tension pin. The rightmost back tension pin is vertically aligned with the right side surface of the support end. The distance between the leftmost back tension pin and the left side surface of the support end is equal to the length of the back tension pin, so that the front tension pins and back tension pins are staggered along the length of the support end.

[0016] In the method for producing an antibacterial glossy fabric as described above, preferably, the elastic fixing device includes a fixing rod, which is a solid cylindrical structure made of iron. Both ends of the fixing rod are fixedly connected to the frame of the spinning machine, and the fixed rod, after connection, is located directly below the lower rear roller. Spring insert slots are evenly spaced along the length of the elastic fixing rod, the number of spring insert slots being the same as the number of spindles on a row of tables of the spinning machine. The spring insert slots are located on the side of the elastic fixing rod. A connecting spring is fitted onto the fixing rod at each spindle position. The connecting spring includes a spring... The spring body is a helical spring composed of a helical rod, which is sleeved on a fixed rod. The insert pin includes a left insert pin and a right insert pin with the same structure. The left insert pin and the right insert pin are solid cylindrical structures. The material of the left insert pin and the right insert pin are the same as the helical rod of the spring body. The diameter of the left insert pin and the right insert pin are the same as the diameter of the helical rod of the spring body. The left insert pin is integrally fixedly connected to the left end of the helical rod of the spring body, and the right insert pin is integrally fixedly connected to the right end of the helical rod of the spring body. The left insert pin connecting the spring is embedded in the spring insert groove. The nested tube at the mounting end of the tension frame is fitted onto the fixed rod. At this time, both ends of the fixed rod protrude through the left and right insertion holes of the nested tube, and the connecting spring is located inside the nested tube. The right insertion pin of the connecting spring is pressed against the inner side of the nested tube, which is close to the spring insertion port. This causes the connecting spring to be compressed when the nested tube at the mounting end of the tension frame rotates around the fixed rod.

[0017] In the production method of the antibacterial glossy fabric described above, it is preferable to use a negative pressure, low temperature, and steam evaporation twisting process in the steam twisting process.

[0018] Compared with existing technologies, this invention uses fine denier bamboo pulp fiber as raw material. By setting a suspended lower carding roller with a carding cloth between the drafting system of the first and second drawing stages and the output trumpet, the straightening and straightening of the front and rear hooks of the fibers in the bamboo pulp sliver is achieved. In the spinning process, a tension frame with tension pins arranged in a staggered pattern on the two sides of the support end that contacts the lower apron is used to achieve stable tension support for the lower apron and reduce the frictional resistance of the support end to the lower apron. This achieves efficient drafting of bamboo pulp roving with high fiber straightness, improves yarn strength, reduces yarn breakage, and thus achieves the high-quality production of bamboo pulp yarn with a high twist coefficient, thereby realizing the production of antibacterial and lustrous fabrics.

Detailed Implementation

[0021] The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0022] This invention provides a method for producing an antibacterial glossy fabric, comprising the following steps: Step 1: Comb the hair into strips Fine denier bamboo pulp fiber with a specification of 1.11dtex×38mm is selected. The selected fine denier bamboo pulp fiber is sequentially processed through an automatic cotton grabbing system with interconnected pipelines, a multi-compartment cotton blending system, a carding needle and beater with a cotton condenser to open the cotton, a vibrating cotton feeding system, a cotton cleaning and smoothing system including a balance adjustment device and a beater opening device, and a carding system with a cotton box to produce fine denier bamboo pulp sliver.

[0023] The selected fine denier bamboo pulp fiber is laid in the disc of the automatic cotton grabber. After the cotton grabber beats the fiber on the surface of the fine denier bamboo pulp fiber layer, it is grabbed by negative pressure adsorption.

[0024] The fine denier bamboo pulp fibers are grasped and mixed in large quantities under the input-output time difference or the input-output path difference through 8-10 high cotton bins of the multi-bin cotton blender.

[0025] The mixed fine denier bamboo pulp fibers are opened by a carding and beating machine, which separates and removes the exposed impurities.

[0026] After being opened, the fine denier bamboo pulp fibers are vibrated and fed to the cotton to ensure uniform flow of fine denier bamboo pulp fibers. The fibers are then continuously conveyed to the cotton cleaning and leveling machine in front. The cotton cleaning and leveling machine uses the balance adjustment device and the beater opening device from the single-beater lap machine.

[0027] After processing, the fine denier bamboo pulp fiber stream is uniformly processed under the input control of the balance adjustment device of the cotton cleaning and leveling machine, so as to achieve uniform transportation of the fine denier bamboo pulp fiber stream. Then, it is opened by the beater opening device under free impact, which further reduces the bonding force between the fibers in the uniformly transported fine denier bamboo pulp fiber stream.

[0028] The fine denier bamboo pulp fiber stream is fed into the cotton box of the carding machine in a uniform fiber bundle state.

[0029] Fine denier bamboo pulp fiber bundles are processed by the licker-in rollers of a carding machine to hold and strike the fibers, then by the cylinder-flat carding process, followed by the transfer and cohesion of the fibers by the doffer to form a web, and finally by the gathering of the fibers at the bell mouth to form a sliver, thus producing fine denier bamboo pulp sliver.

[0030] Step 2: Sorting and combining The process employs a three-stage drawing process. In the first stage, six fine denier bamboo pulp slivers are fed in together. After being gathered and combined, these slivers enter the drafting system and undergo a large back zone drafting action of more than 1.7 times to straighten the fiber hooks within the sliver. After further drafting in the front zone, the desired fine denier bamboo pulp sliver linear density is obtained. A suspended lower carding roller with a straightening needle cloth is set at the front of the drafting system, and the rotational linear speed of the lower carding roller is set to 1.05-1.1 times the speed at which the fine denier bamboo pulp sliver is output from the drafting system. This creates a speed difference between the straightening needle cloth and the fine denier bamboo pulp sliver. Under the action of this speed difference, the front-end hooks of the fibers in the fine denier bamboo pulp sliver, which are also the rear-end hooks of the fibers in the fine denier bamboo pulp sliver, are straightened. After being gathered through a bell mouth, the fibers enter between the output pressure rollers. After being pressed and processed by the output pressure rollers, the fine denier bamboo pulp sliver is obtained and continuously coiled within the sliver can.

[0031] In the second drawing process, six fine denier bamboo pulp slivers are fed in together. After being gathered and combined, the six fine denier bamboo pulp slivers enter the drafting system. They undergo a moderate back zone drafting action of 1.4-1.6 times to straighten the fiber curvature within the sliver. After further front zone drafting, the desired fine denier bamboo pulp sliver is obtained. A suspended lower carding roller with a straightening needle cloth is set at the front of the drafting system. The rotational linear speed of the lower carding roller is set to 1.01-1.05 times the speed at which the fine denier bamboo pulp sliver is output from the drafting system. This creates a speed difference between the straightening needle cloth and the fine denier bamboo pulp sliver. Under the action of this speed difference, the front hooks of the fibers in the fine denier bamboo pulp sliver, i.e., the front hooks of the fibers in the fine denier bamboo pulp raw sliver, are straightened. After being gathered through the bell mouth, the fibers enter between the output pressure rollers. After being pressed and processed by the output pressure rollers, a semi-cooked fine denier bamboo pulp sliver is obtained and continuously coiled in the sliver can.

[0032] In the third drawing process, six fine denier bamboo pulp semi-cooked slivers are fed in together. After being gathered and combined, the six fine denier bamboo pulp semi-cooked slivers enter the drafting system. After being drafted in a small back zone of up to 1.4 times the strength, the fiber distribution within the semi-cooked sliver is made uniform. After being drafted in the front zone, the fine denier bamboo pulp sliver with the required linear density is obtained. After being gathered at the bell mouth, it enters the output pressure roller pair. After being pressed and shaped by the output pressure roller, the fine denier bamboo pulp cooked sliver is obtained and continuously coiled in the sliver can.

[0033] Step 3: Twisting into yarn The fine denier bamboo pulp sliver obtained in the second step is subjected to a roving process with a small draft of no more than 10 times and a weak twist coefficient of no more than 120 to produce fine denier bamboo pulp roving.

[0034] Fine denier bamboo pulp roving is twisted at a high draft of over 30 times and a twist coefficient of over 700 in the spinning process to obtain fine denier bamboo pulp high-twist yarn. The spinning process uses a ring spinning machine that includes a drafting system and a twisting system. The drafting system includes a back drafting roller pair, a middle drafting roller pair, and a front drafting roller pair. A fixed lower pin is set on the lower drafting roller of the middle drafting roller pair. A lower long apron is fitted on the lower drafting roller and the fixed lower pin, and the lower part of the lower long apron is supported by an elastic apron tension frame. An elastic upper pin is set on the upper drafting rubber roller of the middle drafting roller pair. An upper short apron is fitted on the upper drafting rubber roller and the elastic upper pin. The apron tension frame includes a tension frame and an elastic fixing device.

[0035] Reference Figure 1 As shown, the tension frame includes an installation end 1, a connector 2, and a support end 3.

[0036] The mounting end 1 includes a nesting cylinder 15, which is a hollow and closed cylindrical structure made of nylon. A left insertion hole 4 is formed on the left end of the nesting cylinder 15. The center of the left insertion hole 4 is aligned with the center of the left end of the nesting cylinder 15. A right insertion hole 5 is formed on the right end of the nesting cylinder 15. The center of the right insertion hole 5 is aligned with the center of the right end of the nesting cylinder 15. The left insertion hole 4 and the right insertion hole 5 are completely aligned. Similarly, a spring insert 6 is provided along the axial direction of the side of the nested cylinder 15. The spring insert 6 has an arc-shaped structure, and the length direction of the spring insert 6 is consistent with the length direction of the nested cylinder 15. The arc of the spring insert 6 is between 1 / 5 and 1 / 4 of the circumference. A connecting piece is provided on the outer side of the nested cylinder 15 adjacent to the spring insert 6. The connecting piece has a cuboid structure, and one side of the connecting piece is integrally fixedly connected to the outer side of the nested cylinder 15. The connecting piece is made of nylon.

[0037] A connector 2 is provided in front of the mounting end 1. The connector 2 includes a rear fixing part and a front connecting part. The connector 2 is made of nylon. The rear fixing part is a right triangular prism structure with a right-angled triangle base. One side of the rear fixing part is fixedly connected to the connecting piece, so that the side edges where the other two sides of the rear fixing part are connected face forward, forming the forward connecting edge of the rear fixing part. The right-angled edge of the bottom surface of the rear fixing part is vertically aligned with the right end circular surface of the nested cylinder 15. The front connecting part is a cuboid structure. The rear side of the front connecting part is fixedly connected to the forward connecting edge of the rear fixing part, so that the right side of the front connecting part is vertically aligned with the right end circular surface of the nested cylinder 15.

[0038] A support end 3 is provided on the left side of the front connector. The support end 3 is made of nylon and has a cuboid structure. The right side of the support end 3 is fixedly connected to the left side of the front connector. After connection, the lower side of the support end 3 is horizontally aligned with the lower side of the front connector. The length direction of the support end 3 is consistent with the length direction of the nested cylinder 15. The left side of the support end 3 is vertically aligned with the left end circular surface of the nested cylinder 15. The height of the support end 3 is less than the width of the front connector, so that the part of the front connector located between the upper side of the support end 3 and the upper side of the front connector after connection constitutes a right baffle. A left baffle 16 is provided on the left side of the support end 3. The left baffle 16 is made of nylon and has a cuboid structure. The width of the left baffle is consistent with the width of the support end 3. The right side of the left baffle 16 is fixedly connected to the left side of the support end 3. After connection, the upper side of the left baffle 16 is horizontally aligned with the upper side of the right baffle 17.

[0039] Pretensioning pins 13, made of nylon and solid semi-cylindrical in shape, are arranged at equal intervals along the front edge of the upper side of the support end 3. The rectangular bottom surface of each pretensioning pin 13 is fixedly connected to the upper side of the support end 3, and the front edge of the rectangular bottom surface of the pretensioning pin 13 is vertically aligned with the front edge of the upper side of the support end. The distance between two adjacent pretensioning pins 13 is equal to the length of the pretensioning pin 13. The leftmost pretensioning pin 13 is vertically aligned with the left side of the support end 3, and the distance between the rightmost pretensioning pin 13 and the right side of the support end 3 is equal to the length of the pretensioning pin 13. Along the rear edge of the upper side of the support end 3... The support end 3 is provided with equally spaced back tension pins 14. The back tension pins 14 and the front tension pins 13 are identical in structure and material. The rectangular bottom surface of the back tension pin 14 is fixedly connected to the upper side surface of the support end 3. After connection, the front side of the rectangular bottom surface of the back tension pin 14 is vertically aligned with the rear side of the upper side surface of the support end. The distance between two adjacent back tension pins 14 is equal to the length of the back tension pin 14. The rightmost back tension pin 14 is vertically aligned with the right side surface of the support end 3. The distance between the leftmost back tension pin 14 and the left side surface of the support end 3 is equal to the length of the back tension pin 14, so that the front tension pins 13 and the back tension pins 14 are staggered along the length direction of the support end.

[0040] The elastic fixing device includes a fixing rod 8, which is a solid cylindrical structure made of iron. Both ends of the fixing rod 8 are fixedly connected to the frame of the spinning machine, and the fixed rod 8, after connection, is located directly below the lower rear roller.

The connecting spring 7 includes a spring body 10 and an insert pin. The spring body 10 is a helical spring composed of a helical rod. The spring body 10 is sleeved on the fixed rod 8. The embedded pins include a left embedded pin 11 and a right embedded pin 12 with the same structure. The left embedded pin 11 and the right embedded pin 12 are solid cylindrical structures. The material of the left embedded pin 11 and the right embedded pin 12 is the same as that of the spiral rod of the spring body 10. The diameter of the left embedded pin 11 and the right embedded pin 12 is the same as that of the spiral rod of the spring body 10. The left embedded pin 11 is integrally fixedly connected to the left end of the spiral rod of the spring body 10, and the right embedded pin 12 is integrally fixedly connected to the right end of the spiral rod of the spring body 10. The left embedded pin 11 connecting the spring 7 is embedded in the spring embedded groove 9.

[0041] The nested cylinder 15 of the mounting end 1 of the tension frame is fitted onto the fixed rod 8. At this time, both ends of the fixed rod 8 extend out through the left insertion hole 4 and the right insertion hole 5 of the nested cylinder 15. The connecting spring 7 is located inside the nested cylinder 15. The right insertion pin 12 of the connecting spring 7 is pressed against the inner side of the nested cylinder 15, which is close to the spring insertion port 6. This causes the nested cylinder 15 of the mounting end 1 of the tension frame to compress the connecting spring 7 when it rotates around the fixed rod 8, thereby causing the support end 3 of the tension frame to generate an elastic force.

[0042] Take the production of fine denier bamboo pulp tightly twisted yarn with a linear density of 9.84 tex and the corresponding fabrics as an example.

[0043] (1) Raw material selection The raw material is 100% fine denier bamboo pulp fiber with a specification of 1.11dtex×38mm, moisture regain of 12.18%, dry breaking strength of 2.38cN / dtex, and wet breaking strength of 1.25cN / dtex.

[0044] (2) Process flow FA002 Automatic Cotton Picker → FA022 Multi-Compartment Cotton Blender → FA106E Carding and Beating Opener (with 030A Cotton Condenser) → FA201B Carding Machine → Modified FA316B Drawing Frame → Modified FA316B Drawing Frame → D81L Drawing Frame with Self-Leveling System → FA467E Roving Frame → FA506 Spinning Frame with Patented Apron Tensioner Warp yarn: NO.21-S fully automatic tray winding → KY6081 warping machine → GA333 sizing machine Weft yarn: BTZS-6BS-EL type steaming machine → NO.21-S fully automatic tray self-winding → BTZS-6BS-EL type steaming machine Weaving: SPR700 air-jet loom (3) Key process parameters During the opening and cleaning process, the following technological principles are adopted: "humidification and moisture retention, reduction of static electricity, flexible opening, frequent and light picking, fast feeding of thin cotton, and smooth transfer." The speed of the beaters on each individual machine is reduced to improve the efficiency of the machine and protect the fibers to reduce the generation of short fibers. An ultrasonic humidifier is installed on the automatic cotton picker to continuously atomize and humidify the raw material as the trolley moves to reduce static electricity. The beater extends 2.5mm beyond the ribs, the trolley speed is 2.37r / min, and the lowering stroke of the beater is adjusted to the minimum while ensuring supply, so as to achieve frequent and light picking and reduce the weight of the cotton clumps picked up. The cotton box of the carding beater is adjusted to the narrowest point, the cotton feeding roller is adjusted to 35r / min, the beater speed is reduced to 360r / min, and the distance between the beater and the cotton stripping knife is 1.6mm.

[0045] In carding, the process principle of "low speed, medium basis weight, tight spacing, and low tension" is adopted. The spacing between the feed plate and the licker-in roller is appropriately increased, the licker-in roller speed is reduced, and the licker-in roller tooth density is decreased. The spacing between the doffer and the stripping roller and the upper and lower rollers is kept relatively tight, and the tension drafting is appropriately reduced. In sliver drawing, the technical measures of using graphene rubber rollers, higher humidity, heavy pressure, medium basis weight, large spacing, and slow speed are adopted.

[0046] The process of roving adopts medium weight, heavy pressure, large spacing, small back zone draft ratio, and low speed. The process of spinning adopts compact Siro spinning production process. The compact spinning device adopts grid ring type, and the grid ring is selected as Astrosun 124×25BA model, with a negative pressure of 2400Pa and a twist of 2300 twists / m.

[0047] The winding speed in the winding drum is 1000 m / min, and the photoelectric ZENIT electro-cleaner is selected with a relatively strict threshold.

[0048] To avoid increasing yarn breakage during warping, the following measures are taken: Ensure all bobbins on the warp beam are of the same size and have consistent tension; the yarn tension on the warp beam is higher in the back row than in the front row, and higher in the upper and lower layers than in the middle layer, with a three-section tension configuration. Utilize the different angles of the yarn around the reed teeth to configure tension plates of varying quality based on actual conditions, and ensure the channel between the yarn and the guide eye is clean; thread the front row bobbins from bottom to top, starting from the center of the reed and moving outwards sequentially. The lower tension front row yarns are threaded through the middle reed teeth with larger bend angles, while the higher tension back row yarns are threaded through the edge reed teeth with smaller bend angles, compensating for tension differences caused by the different positions of the front and back rows, thus promoting uniform yarn tension; use a reed swing device to prevent point-to-point wear of the reed by the yarn, ensuring even yarn arrangement and smooth winding of the warp beam.

[0049] In the sizing process, the amount of PVA-1799 is reduced and the amount of YX-100 modified starch and ADC polypropylene sizing agent is appropriately increased. The moisture regain of the sizing is controlled at 10%~12%, the temperature is controlled at 85℃~90℃, and the sizing rate is stable at 9%~10%.

[0050] After the vacuum is drawn to 400Pa during the steaming process, the water is heated to 65℃ in the negative pressure vessel to generate low-temperature steam for steaming. The steaming time is maintained for 15 minutes, and then the temperature is raised to 78℃. After the vacuum is drawn to 500Pa, the temperature is maintained for 25 minutes, and then the yarn is removed from the vessel for use.

[0051] During weaving, the tension value on the loom is set to 1100N; a "double opening" process is adopted, and the phase angle of the tread plate is adjusted so that the phase angles of the two openings differ by 20°; the relative humidity is controlled between 66% and 72%.

[0052] (4) Quality testing and analysis Quality test of fine denier bamboo pulp high twist yarn:

[0053] For comparative analysis, the corresponding fine denier bamboo pulp high-twist yarn was processed using traditional production techniques, as follows: FA002 Automatic Cotton Picker → FA022 Multi-compartment Cotton Blender → FA106E Carding and Beating Cotton Opener (with 030A Cotton Condenser) → FA201B Carding Machine → FA316B Drawing Frame → D81L Drawing Frame with Self-Adjusting Leveling → FA467E Roving Frame → FA506 Spinning Frame → NO.21-S Fully Automatic Tray Winding Machine

[0054] The corresponding yarn quality was tested, and the test results clearly show that this patent achieves fiber straightening by setting a suspended lower carding roller with a carding cloth between the drafting system of the first and second drawing stages and the output trumpet. In addition, a low-friction apron tension frame is used in the spinning process to achieve efficient drafting of bamboo pulp roving with high fiber straightness, thereby improving the overall quality of the yarn.

[0055] The above description, based on the embodiments shown in the figures, details the structure, features, and effects of the present invention. The above description is only a preferred embodiment of the present invention, but the present invention is not limited to the scope of implementation shown in the figures. Any changes made in accordance with the concept of the present invention, or equivalent embodiments modified to have equivalent changes, that do not exceed the spirit covered by the specification and figures, should be within the protection scope of the present invention.
