Description

Technical Field

[0001] The present invention relates to the technical field of bandage fabrics, and particularly to a new knitted sports bandage fabric and a production method thereof. Background Art

[0002] Sports bandages have evolved from basic medical supplies to high-performance products that integrate materials science and sports medicine, and their evolution reflects the refined pursuit of human needs for sports health. In the future, they may further combine with wearable technologies and bioengineering to expand the functional boundaries.

[0003] The sports bandage fabrics currently in use have the defects that they are prone to unraveling during production and cutting, and cannot be cut into more diverse edge shapes. In addition, their tissue structures are unstable, and the fibers are prone to sliding and shifting, resulting in skin exposure, poor abrasion resistance, and insufficient protection performance under extreme conditions. Therefore, the present invention proposes a new knitted sports bandage fabric and a production method thereof that can solve the above problems. Summary of the Invention

[0004] The purpose of the present invention is to provide a new knitted sports bandage fabric and a production method thereof to solve the problems raised in the above background art.

[0005] To achieve the above purpose, the present invention provides the following technical solutions:

[0006] A new knitted sports bandage fabric, which is woven by multiple guide bars on a warp knitting machine;

[0007] The yarn threading method of the first guide bar GB1 is full threading with elastic yarn, and the chain stitch is knitted in a movement mode with the laying-in digital code 0-1 / 1-0 / / ;

[0008] The yarn threading method of the second guide bar GB2 is full threading with the first support yarn, and the weft insertion stitch is knitted in a movement mode with the laying-in digital code 0-0 / x+4-x+4 / / ;

[0009] The yarn threading method of the third guide bar GB3 is full threading with the second support yarn, and the plain stitch is knitted in a movement mode with the laying-in digital code 1-0 / y+3-y+4 / / ;

[0010] Wherein, x and y are natural numbers.

[0011] As a preferred technical solution, the elastic yarn is spandex yarn, and the first support yarn and the second support yarn are nylon yarn or polyester yarn.

[0012] As a preferred technical solution, the spandex yarn used has a fineness of 20D to 300D, and the nylon yarn or polyester yarn used has a fineness of 20D to 300D.

[0013] As a preferred technical solution, the weft insertion structure knitted by the second guide bar GB2 is a partial weft insertion structure or a full-width weft insertion structure.

[0014] As a preferred technical solution, the value range of y is 0 to 56.

[0015] A production method of a fabric is also provided, which is applied to any of the above technical solutions, and is characterized by including the following steps:

[0016] S1. On a warp knitting machine, multiple guide bars are used for knitting. The yarn threading method of the first guide bar GB1 is full threading of elastic yarns, and a chain stitch structure is knitted in a movement mode with a laying-in digital of 0-1 / 1-0 / / . The yarn threading method of the second guide bar GB2 is full threading of the first support yarn, and a weft insertion structure is knitted in a movement mode with a laying-in digital of 0-0 / x+4-x+4 / / . The yarn threading method of the third guide bar GB3 is full threading of the second support yarn, and a tricot stitch structure is knitted in a movement mode with a laying-in digital of 1-0 / y+3-y+4 / / ;

[0017] S2. Then, the knitted grey fabric is successively passed through washing, pre-setting, dyeing, dehydration, and setting to finally obtain the sports bandage fabric.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0019] The first guide bar GB1 uses a chain stitch structure to endow the fabric with longitudinal elasticity. After the knitted grey fabric is processed and set by a special drying device, the spandex yarns are maximally shrunk longitudinally. While maintaining a low elastic modulus, the longitudinal stretching length of the fabric is further increased. The second guide bar GB2 uses a partial or full-width weft insertion structure to control the stability of the fabric's transverse dimension, with no transverse elasticity, and plays a certain supporting role in the transverse direction during longitudinal stretching and pulling to prevent transverse contraction. The third guide bar GB3 makes the overall structure of the fabric stable, allowing for arbitrary cutting during production without unraveling, enabling the cutting of richer edge shapes, and ensuring that the bandage does not slip or unravel during arbitrary pulling in daily use, with excellent protective performance;

[0020] The coil structure of the large needle movement tricot stitch of GB3 disperses stress through the transverse connection of the extension yarns. At the same time, the directional arrangement of the warp yarns and the low Poisson's ratio characteristics jointly inhibit the transverse contraction deformation and control the longitudinal stretching limit. The partial weft insertion or global weft insertion ensures that the transverse direction cannot be stretched through inelastic yarns. Description of the Drawings

[0051] Example Six

[0052] New knitted sports bandage fabric:

[0053] The new knitted sports bandage fabric is knitted by multiple guide bars on a warp knitting machine;

[0054] The yarn threading method of the first guide bar GB1 is full threading with spandex filaments. The thickness of the spandex filaments used is 100D, and the chain stitch structure is knitted in the movement mode of laying-in digital 0-1 / 1-0 / / .

[0055] The yarn threading method of the second guide bar GB2 is full threading with polyester filaments. The thickness of the polyester filaments used is 100D, and the partial weft insertion structure is knitted in the movement mode of laying-in digital 0-0 / x+4-x+4 / / , where x is restricted by the width of the grey fabric woven by the used warp knitting machine, or the full-width weft insertion structure is used;

[0056] The yarn threading method of the third guide bar GB3 is full threading with polyester filaments. The thickness of the polyester filaments used is 100D, and the plain stitch structure is knitted in the movement mode of laying-in digital 1-0 / 59-60 / / .

[0057] Specifically, for this new knitted sports bandage fabric, the first guide bar GB1 uses the chain stitch structure to endow the fabric with longitudinal elasticity. After the knitted grey fabric is processed and shaped by a special drying equipment, the spandex filaments shrink to the maximum extent longitudinally. While maintaining a low elastic modulus, the longitudinal stretching length of the fabric is further increased. The second guide bar GB2 uses the partial or full-width weft insertion structure to control the stability of the fabric's transverse dimension, with no transverse elasticity, and plays a certain supporting role in the transverse direction when the fabric is longitudinally stretched and pulled, preventing transverse shrinkage. The third guide bar GB3 makes the overall structure of the fabric stable, allowing for arbitrary cutting during production without unraveling, enabling the cutting of richer edge shapes, and ensuring that the bandage does not slip or unravel during arbitrary pulling in daily use, with excellent protective performance;

[0058] Among them, the longer extension lines of the GB3 large-shift needle plain stitch structure are cross-locked by multiple chain stitch structures of GB1, and the stability of the coils is further enhanced through high-temperature setting. Therefore, when stretched longitudinally, the coils are not prone to sliding, avoiding chain-like transverse deformation. As a result, the transverse dimension is more stable and does not shrink. Moreover, since the transverse yarns are not significantly compressed, and the plain stitch structure of the GB3 large-shift needle exhibits a low Poisson's ratio (the ratio of transverse strain to longitudinal strain), the transverse shrinkage is extremely small or even negligible.

[0059] In summary, the coil structure of the GB3 large-shift needle plain stitch structure disperses stress through the transverse connection of the extension lines. At the same time, the directional arrangement of the warp yarns and the low Poisson's ratio characteristics jointly inhibit the transverse shrinkage deformation and control the longitudinal tensile limit. Local weft insertion or global weft insertion with inelastic yarns ensures that the fabric cannot be stretched transversely.

[0060] Although the embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
