Description

Technical Field

[0001] The present invention relates to the technical field of knitting, and particularly relates to a sinker for a single-sided circular weft knitting machine and a knitting process. Background Art

[0002] The currently well-known single-sided circular weft knitting machine is a complete loop-forming system, and its knitting process is usually composed of various single-sided composite tissues combined by three knitting methods: loop-forming, tucking, and non-knitting (also known as float). The common feature of the weft knitted fabric knitted by the single-sided circular weft knitting machine is that the unit loops of each row are strung or interwoven with the loop-forming, non-knitting or tucking composite tissues of the previous row, resulting in the following many disadvantages in the weft knitted fabric knitted by the existing single-sided circular weft knitting machine: (1) Poor dimensional stability: resulting in a large shrinkage rate and easy deformation. (2) Prone to unraveling and curling: prone to unraveling and curling during cutting and sewing. (3) Not stiff enough: the fabric surface is relatively soft and lacks a certain degree of stiffness. (4) Prone to pilling: prone to pilling when knitting chemical fiber weft knitted fabrics. Summary of the Invention

[0003] Therefore, in view of the above problems, the present invention provides a sinker for a single-sided circular weft knitting machine and a knitting process, which can change the characteristics of the existing weft knitted fabric, improve the knitting dimensional stability of the single-sided circular weft knitting machine, reduce the shrinkage rate, reduce unraveling and curling, resist pilling, and improve the fabric physical properties.

[0004] To solve this technical problem, the present invention adopts the following solution: A sinker for a single-sided circular weft knitting machine includes a plurality of first sinkers disposed on the needle cylinder of the single-sided circular weft knitting machine and corresponding to the sinker cams. The first sinker includes a first heel track and a first lower jaw disposed at the front end of the first heel track. A first lower throat is correspondingly provided on the holding plane of the first lower jaw. A first heel is provided at the middle or rear end of the first heel track and protrudes upward to cooperate with the sinker cam. A first air flow guiding groove with an asymmetric streamline V-shaped cross-section is provided at the rear end of the first lower jaw and faces the first lower throat. The lower part of the inner cavity of the first lower jaw is a first waveform curve-shaped self-tightening part.

[0005] Further, a first upper jaw is provided above the front end of the first heel track and on the first lower jaw. A first upper throat is correspondingly provided on the holding plane of the first upper jaw, and a first nose is provided above the first upper throat.

[0006] Further, a first fin-shaped floc scraping part is provided at the upper part of the rear end of the first air flow guiding groove and extends towards the first heel track and is in clearance fit with the end face of the sinker cam.

[0007] Further, it further includes a plurality of second sinkers disposed on the cylinder of the single jersey circular knitting machine and corresponding to the sinker cams. The second sinkers include second heel tracks and second nose portions disposed at the front ends of the second heel tracks. The plurality of first sinkers and the plurality of second sinkers are arranged in a mixed manner on the cylinder of the circular knitting machine.

[0008] Furthermore, the plurality of first sinkers and the plurality of second sinkers disposed on the cylinder of the single jersey circular knitting machine are arranged in a mixed and alternating manner.

[0009] A single jersey circular knitting machine knitting process based on the above-mentioned sinkers for a single jersey circular knitting machine includes a single jersey circular knitting machine. The knitting methods of the single jersey circular knitting machine include loop knitting, tuck knitting, and float knitting performed by the sinker cams in cooperation with the first sinkers. The knitting methods of the single jersey circular knitting machine further include reserved loop knitting performed by the sinker cams in cooperation with the first sinkers; The reserved loop knitting includes the following steps: S1. Starting from loop knitting, the yarn is fed into the hook of the knitting needle and bent and knitted into a loop with the first lower jaw of the first sinker to form an original loop in the hook of the knitting needle. S2. Then, the original loop and the sinker loop in the hook of the knitting needle are held by the first lower throat of the first sinker, and the knitting needle rises along the cylinder cam in coordination with the first heel track. At this time, the original loop in the hook of the knitting needle forces the latch to open and slides below the latch to complete the loop withdrawal. S3. When the first heel of the first sinker is pushed to the innermost point towards the inner diameter of the cylinder along the first heel track, the knitting needle descends, causing the latch to flip upward under the action of the original loop. S4. The yarn is fed into the hook of the knitting needle and bent and knitted with the first upper jaw of the first sinker to form a new loop of a set length. At this time, the original loop is separated on both sides of the latch. S5. The knitting needle further descends, and the original loop pushes the latch to close and form a loop. The new loop is laid on the first upper jaw of the first sinker to form a new long sinker loop and a needle loop arc, completing the reserved loop knitting.

[0010] Further, during the reserved loop knitting, different lengths of sinker loops are formed by the first sinkers disposed on the upper plate and the sinker cams making different amplitudes of pushing and non-pushing movements in cooperation.

[0011] Another single jersey circular knitting machine knitting process based on the aforementioned sinkers for a single jersey circular knitting machine includes a single jersey circular knitting machine. The knitting methods of the single jersey circular knitting machine include loop knitting, tuck knitting, and float knitting performed by the sinker cams in cooperation with the first sinkers. The knitting methods of the single jersey circular knitting machine further include reserved tuck knitting performed by the sinker cams in cooperation with the first sinkers; The reserved tuck knitting includes the following steps: S1. Starting from the loop formation, the yarn is fed into the hook of the knitting needle and is bent and looped with the first lower jaw of the first sinker to form a loop in the hook of the knitting needle, forming an original loop. S2. Then, the original loop and the sinker loop in the hook of the knitting needle are held by the first lower throat of the first sinker, and the other knitting needle rises along the needle cylinder cam in cooperation with the first cam track. At this time, the original loop in the hook of the knitting needle forces the latch to open and slides above the latch. The loop in the upper row of the original loop and below the latch is called the old loop. S3. When the first heel of the first sinker is pushed to the innermost point along the first cam track towards the inner diameter of the needle cylinder, the knitting needle descends, causing the latch to flip upward under the action of the original loop. S4. The yarn is fed into the hook of the knitting needle and is bent with the first upper jaw of the first sinker to form a new loop of a set length. At this time, the newly fed loop and the original loop in the hook are separated on both sides of the latch by the old loop. S5. The knitting needle further descends, and the old loop pushes the latch to close and loop. The new loop lays yarn on the first upper jaw of the first sinker to form a new long sinker loop and a stitch arc, completing the reserved tuck knitting.

[0012] Furthermore, during knitting, the reserved tuck knitting action is carried out by the first sinker and the sinker cam on the upper plate making different amplitudes of pushing and non-pushing actions in cooperation to form sinker loops of different lengths.

[0013] By adopting the foregoing technical solutions, the beneficial effects of the present invention are as follows: By arranging a newly developed sinker on the upper plate of a single-sided circular weft knitting machine in cooperation with the sinker cam, multiple combinations of the double jaws and double heels of the sinker with the sinker cam are used to design a new weaving method on the single-sided circular weft knitting machine: reserved loop knitting and reserved tuck knitting, that is, between the traditional loop formation, tuck, and float basic combination weaving methods, a reserved loop knitting action between loop formation and tuck and a reserved tuck knitting action between tuck and float are derived to generate new loop forms and more complex fabric processes. The combined application of reserved loop knitting or reserved tuck knitting with the traditional loop formation, tuck, and float makes the weft knitted fabric woven have the following advantages: (1) Good dimensional stability: The realization of the combination of unit loops across rows makes the composite process have good dimensional stability in both the transverse and longitudinal directions, with a small shrinkage rate during wearing and not easily deformed.

[0014] (2) Crispness: The fabric surface is relatively crisp, suitable for making clothes that require a certain degree of crispness.

[0015] (3) Small tendency to ravel: The fabric surface is knitted tightly and will not easily ravel into threads, and the fabric surface is relatively stable.

[0016] (4) Not easily curling: It is not easy to curl during the cutting and sewing processes.

[0017] (5) Good air permeability: Some fabrics adopt the reserved tuck knitting combination to produce a through-hole effect, which has an air conditioning channel effect and a one-way moisture conduction and sweat discharge function.

[0018] By setting an asymmetric streamline V-shaped cross-section air flow guiding groove on the sinker, the pulsed injection of compressed air can be more easily blown into the rear end of the sinker throat to clean the flying fibers that are about to accumulate on the sinker, thus effectively solving the problem that short fiber yarns are prone to accumulate in the forming area of a single-sided circular weft knitting machine, causing cumulative blockage in the sinker grooves of the needle cylinder, which in turn increases the running resistance of the sinkers, makes the equipment load heavier, raises the energy consumption, and is prone to cause wear of objects. It is necessary to disassemble and clean the machine, which is time-consuming and laborious. It avoids many uncertain changes in the fabric quality and effectively extends the cleaning time of the machine. By setting a waveform curve-shaped self-tightening part below the inner cavity of the sinker throat, the inner cavity of the sinker can be effectively enlarged so that the flying fibers generated during the knitting process are not easy to accumulate. The asymmetric streamline V-shaped cross-section air flow guiding groove of the sinker realizes the acceleration of the sinker air flow, and the position distance between the inner cavity and the air flow guiding groove is relatively close, so that the pulsed air flow can penetrate to the lower part of the waveform curve-shaped pre-tightening part of the sinker during the intermittent high-speed reciprocating movement of the sinker, forming a chaotic change in the flow direction and flow velocity at different positions and times in the inner cavity of the sinker, without regularity, and there is a pulsation phenomenon, which makes the flying fibers that may adhere to the sinker peel off and fall off, effectively solving the problem that it is not easy to remove flocs due to the turbulent flow effect of the traditional sinker structure, further effectively extending the cleaning time of the machine, improving the production efficiency, reducing the maintenance cost, and keeping the sinker and the knitting area clean. At the same time, a fin-shaped floc scraping part is arranged at the rear end of the air flow guiding groove of the sinker. Because some of the flying fibers removed by the pulsed injection are attached to the rear part of the asymmetric streamline V-shaped cross-section air flow guiding groove along with the air flow diffusion, a certain accumulation will occur on the triangular end face of the sinker for a long time. The fin-shaped floc scraping part and the triangular end face of the sinker are in clearance fit. When some flying fibers adhere to the triangular end face of the sinker, the fin-shaped floc scraping part contacts the flying fibers and rotates with the needle cylinder to scrape the flying fibers. Due to the centrifugal force, the oblique setting of the fin-shaped floc scraping part can throw the flying fibers towards the outer diameter direction of the needle cylinder, preventing the flying fibers from adhering to the triangular end face of the sinker near the rear part of the asymmetric streamline V-shaped cross-section air flow guiding groove, and avoiding the flying fibers from being woven into the fabric and causing knitting defects. In addition, the transition fit tolerance between the waveform curve-shaped pre-tightening part and the needle cylinder will not cause the sinker to float up and down during the reciprocating movement of the sinker during knitting. The floating is eliminated by the elastic compensation of the waveform curve-shaped pre-tightening part of the sinker and it can slide smoothly, enhancing the holding of the coil and the same auxiliary loop formation, and improving the uniformity of the unit coil shape of the knitted fabric, which is the key factor for knitting high-quality fabrics.By controlling the reserved loop knitting or reserved tuck knitting, different amplitudes of pushing and non-pushing actions are performed by the first sinker and sinker cams set on the top plate during knitting to cooperate with each other for knitting, forming sinker loops of different lengths. Since the lengths of the sinker loops for the reserved loop knitting and reserved tuck knitting in cooperation with the first sinker and sinker cams are longer than those of the traditional loop and tuck stitch arcs, the sinker loops hanging above the upper jaw of the first sinker are longer, which can reserve the corresponding unit yarn length for the next row of knitting, enabling smooth combined knitting. The combination of the knitting needles and the first sinker, and the combination of the multi-segment knitting needles on the lower cylinder and the first sinker on the top plate with the sinker cams form a new knitting process technology, which makes the style and loop shape of the fabric have a higher physical property improvement compared with traditional knitted fabrics and can be widely promoted and applied.

A knitting process for a single-sided circular knitting machine based on the sinker for a single-sided circular knitting machine according to claim 1, comprising a single-sided circular knitting machine, wherein the weaving method of the single-sided circular knitting machine comprises loop knitting, tuck knitting, and float knitting performed by the sinker triangle cooperating with the first sinker, characterized in that: The weaving method of the single-sided circular knitting machine also includes reserved loop weaving performed by the sinker triangle cooperating with the first sinker; The reserved loop weaving comprises the following steps: S1, setting the knitting start based on loop formation, the yarn is fed into the needle hook of the knitting needle and knitted into a loop with the first lower jaw of the first sinker, and the original loop is formed in the needle hook of the knitting needle; S2, then let the original loop and sinker arc in the needle hook of the knitting needle be held by the first lower throat of the first sinker, and the other knitting needle rises along the needle cylinder triangle and the first heel track, at this time, the original loop in the needle hook of the knitting needle is forced to open the needle tongue and slide under the needle tongue to complete the withdrawal; S3, when the first heel of the first sinker is pushed to the innermost point along the first heel track toward the inner diameter of the needle cylinder, the knitting needle descends so that the needle tongue turns upward under the action of the original coil; S4, the yarn is fed into the needle hook of the knitting needle and bent into the first upper jaw of the first sinker to form a new loop of a set length, and the original loop is now separated on both sides of the needle tongue; S5, the knitting needle further descends, the original coil pushes the needle tongue to close the loop, and the new coil yarn forms a new long sinker arc and needle knitting arc on the first upper jaw of the first sinker, completing the reserved loop knitting.

7. The single-sided circular knitting machine knitting process according to claim 6, characterized in that: The reserved loop weaving is performed by the first sinker arranged on the upper disk and the sinker triangle to push out and not push with different amplitudes to cooperate to form sinker arcs of different lengths during weaving.

8. A knitting process for a single-sided circular knitting machine based on the sinker for a single-sided circular knitting machine according to claim 1, comprising a single-sided circular knitting machine, wherein the weaving method of the single-sided circular knitting machine comprises loop knitting, tuck knitting, and float knitting performed by the sinker triangle cooperating with the first sinker, characterized in that: The weaving method of the single-sided circular knitting machine also includes reserved tuck weaving performed by the sinker triangle cooperating with the first sinker; The reserved tuck knitting comprises the following steps: S1, setting the knitting start based on loop formation, the yarn is fed into the needle hook of the knitting needle and knitted into a loop with the first lower jaw of the first sinker, and the original loop is formed in the needle hook of the knitting needle; S2, then let the original loop and the sinker arc in the needle hook of the knitting needle be held by the first lower throat of the first sinker, and the other knitting needle rises along the needle cylinder triangle and the first heel track. At this time, the original loop in the needle hook of the knitting needle is forced to open the needle tongue and slide to the top of the needle tongue, among which the loop in the upper horizontal row of the original loop and located below the needle tongue is called the old loop; S3, when the first heel of the first sinker is pushed to the innermost point along the first heel track toward the inner diameter of the needle cylinder, the knitting needle descends so that the needle tongue turns upward under the action of the original coil; S4, the yarn is fed into the hook of the knitting needle and bent into the first upper jaw of the first sinker to form a new coil of a set length. At this time, the fed new coil and the original coil are separated from the old coil on both sides of the needle tongue in the hook; S5, the knitting needle further descends, the old coil pushes the needle tongue to close the loop, and the new coil yarn forms a new long sinker arc and needle knitting arc on the first upper jaw of the first sinker, completing the reserved tuck knitting.

9. The single-sided circular knitting machine knitting process according to claim 8, characterized in that: The reserved tuck knitting action is performed by the first sinker arranged on the upper disk and the sinker triangle to perform pushing and non-pushing actions of different amplitudes to form sinking arcs of different lengths during knitting.
