Description

Technical Field

[0001] The utility model belongs to the technical field of textiles, in particular to a device for producing ultra-low twist filament staple composite yarns. Background Art

[0002] Knitted underwear requires soft and smooth fabrics to improve wearing comfort. To make the fabrics softer and more comfortable, there are currently two main ways to achieve this.

[0003] 1. The traditional softening method usually uses softeners to soften the fully formed knitted pieces or woven fabrics. At present, the softeners commonly used for softening are silicone softeners. However, the use of softeners will inevitably increase production costs, and because the silicone softeners contain organic solvents, and several commonly used organic solvents are toxic, especially some inferior finishing agents that use solvents that are not environmentally friendly and safe. If they are not thoroughly treated and directly contact the skin, it will not only affect people's health, but also cause environmental pollution.

[0004] 2. If you do not want to add finishing agents to achieve a soft effect, low-twist yarn is usually used to achieve it. Among them, low-twist yarn mainly uses a drafting mechanism to generate roving whiskers from coarse yarn, and then the coarse yarn whiskers are subsequently processed to generate spinning. Among them, the current low-twist spinning with low-torque spinning technology is relatively mature, but the use of low-torque spinning technology, although it can make the knitted fabric achieve a soft effect, after the twist is reduced to a certain extent, the fiber cohesion of the coarse yarn whiskers decreases, resulting in reduced weaving efficiency. After wearing and washing, it is easy to cause elongation and deformation, thereby losing the wearing value. Even if low-torque spinning is used, the yarn twist coefficient will not be too low. Usually, the low-torque spinning twist coefficient is 280 or above. Therefore, the wear resistance of low-torque knitwear is relatively poor, and its products have not been widely recognized in the market. Utility Model Content

[0005] The utility model provides an ultra-low twist filament staple composite yarn production device, which is used to solve the defects in the prior art.

[0006] The utility model is realized through the following technical solutions:

[0007] A device for producing ultra-low twist filament staple composite yarn comprises roving, a drafting mechanism, a front leather roller, a front roller, a yarn guide hook, a bobbin, a steel collar and a wire ring, and is characterized in that it also comprises core-spun filaments, wrapped filaments, an active tension control roller and a fixedly arranged double-groove guide wheel, the core-spun filaments and wrapped filaments pass through the active tension control roller and respectively pass through the corresponding grooves of the double-groove guide wheel, the core-spun filaments and wrapped filaments passing through the corresponding grooves of the double-groove guide wheel and the roving strands formed by the roving are synchronously fed into the jaws formed by the front leather roller and the front roller.

[0008] When the present application is in use, the core-wrapped filament and the wrapping filament are unwound and passed through the active tension control roller, and then passed through the double-groove guide wheel and fed into the nip formed by the front leather roller and the front roller at a certain interval, so that the core-wrapped filament and the wrapping filament have uniform and controllable tension. After the roving passes through the drafting mechanism, roving whiskers are formed; the core-spun filaments are placed in the middle of the roving whiskers through the double-groove guide wheel (when the yarn is Z-twisted, it is in the groove on the left side of the double-groove guide wheel; when the yarn is S-twisted, it is in the groove on the right side of the double-groove guide wheel), and the wrapping filaments are placed in the other groove of the double-groove guide wheel; the core-spun filaments and the wrapping filaments are fed into the jaws formed by the front leather roller and the front roller at a certain interval and output with the roving whiskers, then pass through and drag the wire ring to rotate on the steel collar, so that the core-spun filaments, the wrapping filaments and the roving whiskers are twisted and wound into a tube yarn in one step, and the produced yarn presents a core-spun wrapping structure, that is, the roving whiskers cover the core-spun filaments in the center, and the wrapping filaments are wrapped around the outside of the yarn body in a spiral structure.

[0009] Preferably, the double-groove guide wire wheel includes a left round roller and a right round roller, the left round roller and the right round roller are connected via an intermediate rod, the intermediate rod is fixedly connected to a fixed connecting rod, and the left round roller and the right round roller are provided with grooves along their circumference.

[0010] Preferably, the left and right round rollers are both annular structures and are fixedly sleeved on the outer wall of the bearing, one end of a crossbar is fixedly connected to the inner wall of the bearing, and the other end of the crossbar is connected to the middle rod. Thus, the friction between the core-spun filament and the wrapped filament and the corresponding left and right round rollers can be replaced by rolling friction instead of sliding friction, thereby reducing friction and making the transmission of the core-spun filament and the wrapped filament smoother.

[0011] Preferably, the middle rod has an inner cavity, screw holes are formed on both sides of the inner cavity, and the crossbar is a screw rod and is threadedly connected to the screw holes. The screw rod can rotate in the inner cavity, thereby changing the distance between the left round roller and the right round roller, and then changing the distance between the core-wrapped filament and the wrapped filament, so as to achieve fine adjustment of the distance between the core-wrapped filament and the wrapped filament.

[0012] Preferably, the diameter of the left crossbar is larger than that of the right crossbar, a blind hole is provided on the left crossbar, and the diameter of the blind hole is larger than that of the right crossbar. The right crossbar can penetrate into the blind hole when rotating, so as to further adjust the spacing.

[0013] The beneficial effects of the utility model are as follows: when the present application is used, the produced yarn presents a core-wrapped structure, that is, the coarse yarn wraps the core-wrapped filaments in the center, and the wrapped filaments are wrapped around the outside of the yarn body in a spiral structure. Compared with traditional filament staple yarns, the range of filament mass proportion is increased; since the strength is mainly provided by synthetic filaments, the yarn strength is not restricted by the spinning twist. The twist design is mainly to ensure the stability of the yarn structure and a good coating effect. Under this premise, a lower twist design can be adopted. The twist coefficient of traditional staple yarn is generally above 280. The spinning twist coefficient of this structure can be reduced to 200 or even lower. Therefore, this technology can not only ensure the smooth spinning process and the yarn quality meets the weaving requirements of knitted fabrics, but also allow the knitted fabrics to maintain their original shape after multiple washings. Thereby, while improving the softness and comfort of the knitted fabric, the shape retention of the clothing is also improved. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] An ultra-low twist filament staple composite yarn production device, such as Figure 1-Figure 3 As shown. It includes roving 3, drafting mechanism, front leather roller 6, front roller 7, yarn guide hook 8, bobbin 11, steel ring 9 and wire traveler 10, and is characterized in that it also includes core-spun filament 1, wrapping filament 2, active tension control roller 4 and fixedly arranged double-groove guide wheel 5, the core-spun filament 1 and wrapping filament 2 pass through active tension control roller 4 and respectively pass through corresponding grooves of double-groove guide wheel 5, and the core-spun filament 1 and wrapping filament 2 passing through corresponding grooves of double-groove guide wheel 5 and roving strands 301 formed by roving 3 are synchronously fed into the jaws formed by front leather roller 6 and front roller 7.

[0022] The roving 3 is spun through processes such as cleaning, carding, and drawing according to set process requirements; the core-spun filament 1 is placed in the middle of the original stretched short fiber strands, and the wrapping filament 2 and the core-spun filament 1 are placed on one side of the short fiber strands at equal intervals.

[0023] When the present application is in use, the core-wrapped filament 1 and the wrapping filament 2 are unwound and passed through the active tension control roller 4, and then passed through the double-groove guide wheel 5 and fed into the nip formed by the front leather roller 6 and the front roller 7 at a certain interval, so that the core-wrapped filament 1 and the wrapping filament 2 obtain uniform and controllable tension. After the coarse roving 3 passes through the drafting mechanism, a coarse roving strand 301 is formed; the core-spun filament 1 is placed in the middle of the coarse roving strand 301 through the double-groove guide wheel 5 (when the yarn is Z-twisted, it is in the groove on the left side of the double-groove guide wheel 5; when the yarn is S-twisted, it is in the groove on the right side of the double-groove guide wheel 5), and the wrapping filament 2 is placed in the other groove of the double-groove guide wheel 5; the core-spun filament 1 and the wrapping filament 2 are fed into the jaws formed by the front leather roller 6 and the front roller 7 at a certain interval and are output with the coarse roving strand 301, and then pass through and drag the wire ring 10 to rotate on the steel collar 9, so that the core-spun filament 1, the wrapping filament 2 and the coarse roving strand 301 are twisted and wound into a tube yarn through a one-step method, and the produced yarn presents a core-spun wrapping structure, that is, the coarse roving strand 301 covers the core-spun filament 1 in the center, and the wrapping filament 2 is wrapped around the outside of the yarn body in a spiral structure.

[0024] The double grooved wire guide wheel 5 includes a left round roller 41 and a right round roller 42, which are connected via an intermediate rod 43, which is fixedly connected to a fixed connecting rod, and grooves are provided along the circumference of the left round roller 41 and the right round roller 42. The left round roller 41 and the right round roller 42 are both annular structures and are fixedly sleeved on the outer wall of the bearing, and one end of a cross bar 44 is fixedly connected to the inner wall of the bearing, and the other end of the cross bar 44 is connected to the intermediate rod 43. In this way, the friction between the core-spun filament 1 and the wrapped filament 2 and the corresponding left round roller 41 and right round roller 42 can be replaced by rolling friction instead of sliding friction, thereby reducing friction, so that the core-spun filament 1 and the wrapped filament 2 are transmitted more smoothly.

[0025] The middle rod 43 has an inner cavity 45, and screw holes are formed on both sides of the inner cavity 45. The crossbar 44 is a screw and is threadedly connected to the screw holes. The screw can rotate in the inner cavity, thereby changing the distance between the left round roller 41 and the right round roller 42, and then changing the distance between the core-wrapped filament 1 and the wrapped filament 2, so as to achieve fine adjustment of the distance between the core-wrapped filament 1 and the wrapped filament 2.

The right crossbar 44 can penetrate into the blind hole when rotating, thereby further adjusting the spacing.

[0027] The use of this application produces yarns with a core-wrapped structure, that is, the coarse yarn 301 wraps the core-wrapped filament 1 in the center, and the wrapped filament 2 is wrapped around the outside of the yarn body in a spiral structure. Compared with traditional filament staple yarns, the range of filament mass proportion is increased; since the strength is mainly provided by synthetic filaments, the yarn strength is not restricted by the spinning twist. The twist design is mainly to ensure the stability of the yarn structure and have a good coating effect. Under this premise, a lower twist design can be adopted. The twist coefficient of traditional staple yarn is generally above 280. The spinning twist coefficient of this structure can be reduced to 200 or even lower. Therefore, this technology can not only ensure the smooth spinning process and the yarn quality meets the weaving requirements of knitted fabrics, but also ensure the original shape of the knitted fabrics after multiple washings. Thereby, while improving the softness and comfort of the knitted fabric, the shape retention of the clothing is also improved.
