Description

Technical Field

[0001] The invention relates to the field of woven fabric processing, and in particular to a super-resilient ribbed knitted fabric and a processing method and application thereof. Background Art

[0002] With the continuous development of material technology, flywoven fabrics have emerged and have been developed and applied to maturity. By using computers for design and programming, the yarns are woven into flywoven fabrics according to the computer settings. In the stretching parts of clothing or bags, such as the cuffs and collars of tops, the fabric is not elastic enough, and the cuffs and collars will become loose and deformed over time. In the current market, the uppers produced in the field of woven fabric processing generally choose to use the same fabric for the entire upper, that is, the material and weaving method of the entire upper are single, the purpose is to facilitate operation and minimize the cost of raw materials, machines and labor. Because the wearer's feet squeeze and pull different parts of the upper differently during daily life and exercise, the homogenization of the upper will cause the wear of the easily worn parts of the upper to be more serious than other parts. If the upper texture is hard, it will cause a bad experience for the wearer, and if the upper texture is soft, it will shorten the service life of the shoes. Using the same fabric for the entire upper cannot achieve a balance between the use experience and service life. Summary of the invention

[0003] In order to overcome the shortcomings and deficiencies in the prior art, the object of the present invention is to provide a super-resilient trough knitted fabric and a processing method and application thereof.

[0004] The purpose of the present invention is achieved through the following technical solutions:

[0005] On the one hand, the present invention provides a super-resilient pit-bar knitted fabric, which is knitted from a knitting material through a knitting machine in one step, wherein the knitting material includes an elastic knitting material and other knitting materials, and the super-resilient pit-bar knitted fabric has at least two layers, an outer layer is an elastic knitting material or other knitting material, and an inner layer is an elastic knitting material. The knitted fabric is structurally divided into a convex part and a concave part.

[0006] Elastic woven materials are softer and more elastic than other woven materials. In the inner layer of super-resilient pit-ribbed knitted fabric, they are flexible and elastic. When used on the upper, they can improve the coverage of the upper to the wearer's foot and increase the wearer's comfort. When used on the cuffs and collars of clothing, they can provide greater stretch elasticity and prevent clothing from deforming. Other woven materials are harder and less elastic. In the outer layer of super-resilient pit-ribbed knitted fabric, they make the knitted fabric both wear-resistant and anti-deformation. Elastic woven materials are used alone or in combination with other woven materials. The knitted fabric has at least two layers. Due to the different woven materials and woven methods used, the organizational structure of the knitted fabric produces different effects, that is, the width and height of the convex and concave parts of the knitted fabric can present different effects as the woven materials change.

[0007] Furthermore, the elastic woven material includes at least one of spandex, spandex coating material and high elastic polyester fiber. Spandex is usually not used alone, and most of the time, spandex coating material is used to coat the spandex elastic core-spun yarn. The spandex coating material is a natural fiber-composition elastic core-spun yarn with good touch and appearance. A small amount of spandex can be added to produce high-quality elastic core-spun yarn, and the elasticity of the elastic core-spun yarn can be adjusted according to the application requirements of the knitted fabric.

[0008] Furthermore, the other braiding materials include at least one of filament yarn, staple yarn and monofilament. Filament yarn is smooth and uniform, has luster, has tight and regular yarn arrangement, has high fiber strength utilization coefficient, and has high bending rigidity; staple yarn includes but is not limited to ring-spun yarn, free-end spinning and self-twisted yarn; monofilament is coarser than the single filament in multifilament, and is a single filament prepared by a single-hole spinneret in chemical fiber production.

[0009] Furthermore, the other braided materials include thermal fuses.

[0010] Furthermore, the combination of the woven material includes at least one of a solid yarn and a mixed yarn.

[0011] Furthermore, the knitting machine is a weft knitting computerized flat knitting machine.

[0012] Furthermore, the super-resilient ribbed knitted fabric needs to be heated. The heating temperature does not exceed 180°C. The knitted fabric without hot melt is heated to shrink the knitted material to a more ideal fabric effect; the knitted fabric with hot melt is heated to melt the hot melt and bond the knitted material to a more ideal fabric effect.

[0013] Another aspect of the present invention provides a method for processing the super-resilient trough knitted fabric, wherein the knitted fabric is knitted by a weft knitting computerized flat knitting machine, and at least two yarn mouths are used. The materials used by the yarn mouths include at least one elastic knitting material and other knitting materials. The knitting process is as follows:

[0014] Part 1: Top weaving and bottom weaving are combined with floating line weaving respectively;

[0015] The second part: move the front knitting left or right by one stitch and transfer the needle to the back and move the back knitting left or right by one stitch and transfer the needle to the front, respectively, and combine them with the floating thread knitting;

[0016] The third part: taking the first and second parts as a knitting cycle, knitting is performed several times to form a super-resilient pit strip knitted fabric.

[0017] Furthermore, a method for processing the above-mentioned super-resilient pit strip knitted fabric is provided, wherein the knitted fabric is knitted by a weft knitting computerized flat knitting machine, and at least two yarn mouths are used, and the materials used by the yarn mouths include at least one elastic knitting material and other knitting materials, and the knitting process of the knitted fabric is as follows:

[0018] Part 1: Perform top and bottom weaving;

[0019] The second part: taking the first part as a knitting cycle, knitting is performed several times to form a super-resilient pit strip knitted fabric.

[0020] On the other hand, the present invention aims at the problem that the stretching parts in the uppers, clothes or bags have low elasticity and homogeneous materials, and also provides the use of the above-mentioned super-resilient knitted fabric in the stretching parts in the uppers, clothes or bags.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] The present invention uses a weft knitting computerized flat knitting machine to knit the knitted material into a super-resilient pit strip knitted fabric in one step by designing and programming in advance. If the fabric is all hard, the product will have poor elasticity, causing discomfort to the wearer. If the fabric is all soft, the product will have poor wear resistance and easy wear, shortening the service life. The present invention solves the problem of homogenization of the above-mentioned traditional fabrics. The elastic knitting material is used alone or in combination with other knitting materials. The knitted fabric has at least two layers. Due to the different knitting materials and knitting methods used, the organizational structure of the knitted fabric produces different effects, that is, the width and height of the protruding part and the concave part of the knitted fabric, that is, the pit strip organization, can present different effects with the change of the knitting material. The elasticity is greater than that of ordinary fabrics, and it is not easy to deform, which improves the durability of the product and extends the product life. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The present invention will now be described in detail with reference to the accompanying drawings.

[0031] The present invention provides a super-resilient pit-line knitted fabric which is formed by one-time knitting of elastic knitting material and other knitting materials by a knitting machine. The combination of the knitting materials includes at least one of a sheath yarn and a blended yarn. The knitted fabric has at least two layers, an outer layer of an elastic knitting material or other knitting material, and an inner layer of an elastic knitting material. The knitted fabric is structurally divided into a convex part and a concave part.

[0032] The elastic woven material includes at least one of spandex, spandex coating material and high elastic polyester fiber. Spandex is usually not used alone. Most of the time, spandex is coated with spandex elastic core-spun yarn. The spandex coating material is a natural fiber elastic core-spun yarn with good touch and appearance. High-quality elastic core-spun yarn can be produced by adding a small amount of spandex. The elasticity of the elastic core-spun yarn can be adjusted according to the application requirements of knitted fabrics. The elastic woven material is flexible and elastic. When applied to the upper of a shoe, it improves the covering of the upper to the wearer's foot and increases the comfort of the wearer. It is applied to the cuffs and collars of clothing to provide greater stretch elasticity, and the clothing is not easily deformed.

[0033] Other weaving materials include at least one of filament yarns, staple yarns and monofilaments. Filament yarns are smooth and uniform, have a glossy luster, are tightly and regularly arranged, have a high fiber strength utilization coefficient, and have high bending stiffness; staple yarns include but are not limited to ring-spun yarns, free-end spun yarns, and self-twisted yarns; the fineness of monofilaments is coarser than that of single strands in multifilament yarns, and are single filaments prepared by a single-hole spinneret in the production of chemical fibers. Other weaving materials are relatively hard and less elastic, and are formed on the outer layer of the super-resilient pit-strip knitted fabric, making the knitted fabric both wear-resistant and anti-deformation. Other weaving materials include hot-melt wires, which are woven into the interlayer of the knitted fabric by covering the yarn during the weaving process.

[0034] The weaving materials and weaving methods are different, and the organizational structure of the knitted fabric produces different effects, that is, the width and height of the protruding parts and the concave parts of the knitted fabric can present different effects as the weaving materials are changed.

[0035] Example 1

[0036] Figure 1 This is a physical picture of a super-resilient pit-strip knitted fabric 1, which includes a protruding structure 1 woven from other knitted materials with a relatively hard outer layer and a recessed structure 2 woven from an elastic knitted material with a relatively soft inner layer. Figure 2 This is a real picture of a super-resilient ribbed knitted fabric 2, which is made only of elastic woven material and includes a recessed structure 2 (1) and a protruding structure 2 (2).

[0037] There are multiple weaving methods for objects 1 and 2, one of which is the weaving structure diagram of embodiment 1. Figure 3 As shown in the figure, A and B represent yarn mouths. In object 1, the material used for yarn mouth A is other knitting materials, and the material used for yarn mouth B is elastic knitting material. In object 2, yarn mouths A and B are both elastic knitting materials. The direction of the arrow represents the working direction of the yarn mouth. The needles on the needle bed are named 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18 from left to right.

[0038] In the 1st knitting row of the horizontal axis, the yarn mouth A works to the right, and the surface knitting is performed in the 1-5 needle rows, 7-11 needle rows and 13-17 needle rows of the longitudinal axis, and the 6th, 12th and 18th needle rows are floating threads.

[0039] In knitting row 2, yarn mouth B works to the right, and floating thread knitting is performed in needle rows 1-5, 7-11 and 13-17, and bottom knitting is performed in needle rows 6, 12 and 18.

[0040] In row 3, yarn mouth B works to the left, and floating thread knitting is performed in needle rows 1-5, 7-11 and 13-17, and surface knitting is performed in needle rows 6, 12 and 18.

[0041] In row 4, yarn mouth A works to the left, and base knitting is performed in needle rows 1-5, 7-11 and 13-17, and needle rows 6, 12 and 18 are used as floating threads.

[0042] Weaving rows 1 and 2 constitute a forward stroke of yarn mouth A and yarn mouth B, weaving rows 3 and 4 constitute a return stroke of yarn mouth A and yarn mouth B, that is, weaving rows 1-4 constitute a weaving cycle, and the weaving actions of weaving rows 5-8 are consistent with those of weaving rows 1-4, that is, weaving rows 5-8 constitute the second weaving cycle, weaving rows 11-14 constitute the third weaving cycle, and weaving rows 15-18 constitute the fourth weaving cycle.

[0043] In the 9th and 10th knitting rows, the 6th, 12th and 18th knitting needle rows perform the translational transfer action of the bottom layer and the top layer, which is to translate the bottom knitting and the top knitting of the 6th, 12th and 18th knitting needle rows of the 6th and 7th knitting rows to the left by one needle position, and transfer the original top knitting to the bottom layer, and transfer the original bottom knitting to the top layer. The specific transfer action is as follows:

[0044] In the 9th knitting row, the front knitting is moved one needle to the left and turned to the back in the 6th, 12th and 18th knitting needle rows, that is, the rear needle bed moves one needle position to the right, and the surface knitting of the 6th, 12th and 18th knitting needle rows in the 7th knitting row is turned, and the front needle bed coil is moved to the corresponding needle of the rear needle bed; in the 10th knitting row, the back knitting is moved one needle to the left and turned to the front in the 6th, 12th and 18th knitting needle rows, that is, the rear needle bed moves two needle positions to the left, and the bottom knitting of the 6th, 12th and 18th knitting needle rows in the 6th knitting row is turned, and the rear needle bed coil is moved to the corresponding needle of the front needle bed, and the rear needle bed returns to the knitting state without turning needles.

[0045] In the 19th and 20th knitting rows, the 6th, 12th and 18th knitting needle rows perform the translational transfer action of the bottom layer and the top layer, which is to translate the bottom knitting and the top knitting of the 6th, 12th and 18th knitting needle rows of the 16th and 17th knitting rows to the right by one needle position, and transfer the original top knitting to the bottom layer, and transfer the original bottom knitting to the top layer. The specific transfer action is as follows:

[0046] In the 19th knitting row, the front knitting is moved right by one needle and transferred to the back in the 6th, 12th and 18th knitting needle rows, that is, the rear needle bed moves one needle position to the left, and the surface knitting of the 6th, 12th and 18th knitting needle rows in the 17th knitting row is transferred, and the front needle bed coil is moved to the corresponding needle of the rear needle bed; in the 20th knitting row, the back knitting is moved right by one needle and transferred to the front in the 6th, 12th and 18th knitting needle rows, that is, the rear needle bed moves two needle positions to the right, and the bottom knitting of the 6th, 12th and 18th knitting needle rows in the 16th knitting row is transferred, and the rear needle bed coil is moved to the corresponding needle of the front needle bed, and the rear needle bed returns to the knitting state without transfer.

[0047] The difference between rows 1-10 and rows 11-20 is that rows 9 and 10 perform the action of moving the rear needle bed one needle position to the right and two needle positions to the left, and rows 19 and 20 perform the action of moving the rear needle bed one needle position to the left and two needle positions to the right. Rows 1-10 and rows 11-20 are both complete knitting cycles, and the knitting action of rows 1-10 and rows 11-20 are alternately performed for several knitting cycles to form a super-resilient pit strip knitted fabric.

[0048] After the knitting of the objects 1 and 2 is completed, they are subjected to heating treatment, and the heating temperature does not exceed 180°C. The upper of the shoe without the hot melt is heated to shrink the knitted material to a more ideal fabric effect; the upper of the shoe with the hot melt is heated to melt the hot melt and bond the knitted material to a more ideal fabric effect. If the hot melt is used, the hot melt is knitted in the knitted fabric interlayer through the wool yarn mouth and the knitted materials of the A yarn mouth and the B yarn mouth, and the hot melt is heated and melted to bond the knitted materials. In the object 1, other knitted materials are woven into the protruding structure 1 and the elastic knitted materials are woven into the concave structure 2 to form a pit strip structure. The object 2 is woven from elastic knitted materials. The difference between the concave structure 2 (1) and the protruding structure 2 (2) is smaller than that of the object 1. The elasticity of the elastic knitted material used in the concave structure 2 (1) is greater than that of the elastic knitted material used in the protruding structure 2 (2).

[0051] There are multiple weaving methods for objects 3 and 4, one of which is the weaving structure diagram of embodiment 2. Figure 6 As shown, A and B represent yarn mouths. In Objects 3 and 4, the materials used for yarn mouths A and B are both elastic knitting materials. The direction of the arrow represents the working direction of the yarn mouth. The needles on the needle bed are named 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, and 18 from left to right.

[0052] In knitting row 1, yarn mouth A works to the right, and surface knitting is performed in needle rows 1-3, 7-9, and 13-15, and bottom knitting is performed in needle rows 4-6, 10-12, and 16-18.

[0053] In knitting row 2, yarn mouth B works to the right, and surface knitting is performed in needle rows 1-3, 7-9, and 13-15, and bottom knitting is performed in needle rows 4-6, 10-12, and 16-18.

[0054] In knitting row 3, yarn mouth B works to the left, and surface knitting is performed in needle rows 1-3, 7-9, and 13-15, and bottom knitting is performed in needle rows 4-6, 10-12, and 16-18.

[0055] In row 4, yarn mouth A works to the left, and surface knitting is performed in needle rows 1-3, 7-9, and 13-15, and bottom knitting is performed in needle rows 4-6, 10-12, and 16-18.

[0056] Rows 1 and 2 constitute a forward trip of yarn mouths A and B, rows 3 and 4 constitute a return trip of yarn mouths A and B, that is, rows 1-4 constitute a knitting cycle, rows 5-8 are the same as rows 1-4, that is, rows 5-8 are the second knitting cycle, rows 9-12 are the third knitting cycle, and rows 13-16 are the fourth knitting cycle. The knitting action of rows 1-4 is used to knit several knitting cycles to form a super-resilient pit strip knitted fabric.

[0057] After the knitting of the objects 3 and 4 is completed, they are subjected to heating treatment, and the heating temperature does not exceed 180°C. The upper of the shoe without hot melt is heated to shrink the knitting material to a more ideal fabric effect; the upper of the shoe with hot melt is heated to melt the hot melt and bond the knitting material to a more ideal fabric effect. If hot melt is used, the hot melt is woven into the knitted fabric interlayer through the wool yarn mouth and the knitting material of the A yarn mouth and the B yarn mouth, and the hot melt is heated and melted to bond the knitting material. Both the objects 3 and 4 are knitted with elastic knitting materials. The object 3 is partially hollow needled on the surface, and the object 4 is partially hollow needled on the bottom. Therefore, the concave structure 2 (1) and the convex structure 2 (2) of the object 4 are relatively tight.
