Description

Technical Field

[0001] The present invention relates to the technical field of weaving, and in particular to a multi-nested twill weaving loom, method, fabric structure and shoe upper. Background Art

[0002] A loom is a device that weaves a fabric by crossing warp yarns and weft yarns. When the weft yarn is passed through, if a part of the warp yarns among the warp yarns is lifted, the warp yarns are separated from each other to form an opening, and the weft yarn passes through this opening, thereby weaving the fabric.

[0003] Fabric structures woven by different types of looms include leno structure and jacquard structure: The leno structure refers to a fabric structure in which the warp yarns of two systems, namely the ground and the twill, and one system of weft yarns are twisted with each other. The eyelets formed by the twisting of the warp yarns on the leno fabric are called leno holes; The jacquard structure refers to the pattern or design formed by the floating or interlacing changes of the warp yarns or weft yarns on the fabric surface according to the regular requirements.

[0004] Previous looms can combine the leno structure and the jacquard structure to weave a new fabric structure. The leno structure in this type of fabric structure is often in a single form, and the sizes of a number of ventilation holes formed on the leno structure are the same, such as the Korean patent with the application number 201580060919.2 and the name of loom for weaving fabrics with different structures, shoe upper and shoes woven by using the same; Another example is the Chinese patent with the application number 201710228075.9 and the name of a porous fabric woven by a jacquard loom and its weaving method.

[0005] As described above, previous looms only use one level of heddle combined with a jacquard heddle to realize the weaving of fabric structures, and can neither use a higher level of heddle combined with a jacquard heddle to realize the weaving of new fabric structures, nor combine different levels of heddles to weave a fabric structure containing different types of leno structures. Further, it causes the singleness of the fabric structure constituting the fabric.

[0006] However, when the multi-nested twill weaving loom and the weaving method of the present invention are used, when the fabric structure contains different leno structures, it can also be combined with the jacquard structure, which can not only form ventilation holes of different sizes to increase the air permeability of the fabric, but also no longer limit the form of the fabric structure on the fabric to adapt to various fabrics such as shoe uppers, and can be made into clothing such as shoe uppers. Summary of the Invention

The second-level heddle is composed of a single heddle. The warp yarns pass through the heddle eyelets of the second-level heddle to form cross warp yarns and no longer pass through other heddles in this nested heddle group. The warp yarns pass through the internal space of the second-level heddle to form ground warp yarns. The first-level heddle is composed of m heddles, where m is an integer greater than 1.

[0036] As a preferred embodiment of the present invention, the pattern warp in step S2 passes through from the left or right outside the other heddles of the first - stage heddle.

[0037] A fabric structure with multiple nested twills, including leno weave, The leno weave includes a primary twill region and a secondary twill region formed by warping the same batch of warp yarns in one pass in the warp direction. The heddles of the secondary twill region do not participate in the twill of the primary twill region. All the ground yarns heddled by the heddles of the secondary twill region are divided into m groups. At least one of the divided ground yarns in each group serves as a heddle and at least one serves as a ground yarn to form each primary twill region, thereby forming m corresponding mutually independent primary twill regions. The leno weave includes ventilation holes, which include large holes and small holes. Relatively speaking, large holes are formed between adjacent secondary twill regions, and small holes are formed between adjacent primary twill regions.

[0038] As a preferred embodiment of the present invention, it includes any one or any combination of the three basic weaves and their derivative weaves.

[0039] As a preferred embodiment of the present invention, any one or any combination of the three basic weaves and their derivative weaves is formed between the primary twill region and the secondary twill region in the warp direction.

[0040] As a preferred embodiment of the present invention, the fabric structure constitutes a shoe upper, wherein the leno weave forms the breathable part of the shoe upper, and any one or any combination of the three basic weaves and their derivative weaves maintains the shape of the shoe upper.

[0042] The above technical features can be combined with each other as long as they do not conflict with each other.

[0043] The beneficial effects of the present invention are: 1. Compared with the prior art, the present invention sets up multiple levels of heddles in the nested heddle group, and multiple heddles are set up in the first-level heddle, which can form a multi-level twill region with a larger area. Due to the complex weaving between numerous warp and weft yarns, the multi-level twill region has better strength and better compressive performance; correspondingly, the ventilation holes between the multi-level twill regions also become larger, greatly improving the breathability of the leno weave.

[0044] 2. Compared with the prior art, the leno weave of the present invention is composed of different-level twill regions, increasing the pattern complexity of the leno weave. At the same time, ventilation holes of different sizes are formed between different-level twill regions. The ventilation holes of different sizes fit different parts of the human body better, meeting the different ventilation requirements of different parts.

[0045] 3. In the present invention, the ground warp passes through from the left or right side outside other heddles of the nested ground heddle group, and a form in which the ground warp is located at the outermost or innermost side of the secondary ground weaving area can be formed. The ground warp is tightly woven layer by layer by the warp yarns inside the secondary ground weaving area, and the strength of the ground warp is greatly improved, which is beneficial to maintaining the shape of the secondary ground weaving area under external action.

[0046] 4. When the layout space permits, the m heddles in the first - stage heddle of the present invention are arranged side by side along the weft direction; since each heddle has a certain volume, when it is necessary to reduce the influence of the heddle volume, the m heddles are arranged staggeredly. More specifically, the front and rear heddles are not on the same straight line, but have an obliquely staggered arrangement relationship. Based on this position relationship, the m heddles on the first - stage heddle can simultaneously weave the warp yarns at the front end of the first - stage heddle, improving the weaving efficiency.

[0047] 5. By arranging the first - stage heddle and the second - stage heddle in the loom, and the number of heddles in the first - stage heddle being variable, the present invention can weave different types of fabric structures. Compared with the prior art that can only weave the same type of fabric structure, it has a wider applicable scenario and meets different requirements for fabric weaving.

[0048] 6. Through the principle of multiple nesting, the present invention can also set the next - stage heddle at the rear end of the first - stage heddle to form more - level nesting, providing a larger design space for pattern design, forming different product gradients, and meeting the needs of different customers.

[0049] 7. The ground warp in the previous - stage ground weaving area of the present invention can be woven with the single or multiple ground weaving areas in the next - stage to form different types of fabric structures, enriching the diversity of fabric structures.

Detailed implementation manners

[0051] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention. In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other. The present invention will be further described in detail below with reference to the specific implementation manners.

[0052] The advancing direction of the warp yarns in the loom is as Figure 1 shown.

[0053] As Figure 1 - Figure 2 , a multiple nested twill weaving loom includes a plurality of nested heddle groups 100, the nested heddle groups 100 are arranged in sequence along the weft direction on the loom, and the nested heddle groups 100 include the second-stage heddle 102 at the front end in the advancing direction of the warp yarns and the first-stage heddle 101 at the rear end; The second-stage heddle 102 is composed of a single heddle, the first-stage heddle 101 is composed of m heddles, and m is an integer greater than 1, The second-stage heddle 102 is used to form a leno weave for multiple ground warps, and the first-stage heddle 101 is used to form a leno weave with m heddle groups from the multiple ground warps coming from the second-stage heddle 102.

[0054] As Figure 1 - 2It can be understood that the warp thread passes through the heddle eyelets of the heddles of the second - stage heddle 102 to form the compound warp and no longer passes through other heddles of this nested heddle group 100. The warp thread passes through the inner space of the heddles of the second - stage heddle 102 to form the ground warp. The ground warp passing through the second - stage heddle 102 forms warp threads at the front end of the first - stage heddle 101. The warp threads are divided into m groups. At least one warp thread passes through the heddle eyelets of each group of heddles as the compound warp, and at least one warp thread passes through the inner space of each group of heddles as the ground warp. Each group of compound warp no longer passes through other heddles of the first - stage heddle 101, and each group of ground warp no longer passes through other heddles of the first - stage heddle 101. The shape of the above - mentioned inner space is an inverted A shape.

[0055] Furthermore, not limited to two - level heddles, the nested heddle group 100 further includes the subordinate heddles of the first - stage heddle arranged at the rear end of the first - stage heddle 101 along the warp - thread traveling direction. The subordinate heddles of the first - stage heddle are composed of x heddles, where x is an integer greater than 1. The subordinate heddles of the first - stage heddle are used to form a leno weave structure with x leno groups from the multiple ground warps of at least one heddle among the m heddles of the first - stage heddle 101.

[0056] Of course, along the warp - thread traveling direction, other - level heddles can also be arranged at the rear end of the subordinate heddles to meet the weaving requirements of different fabric structures.

[0057] By arranging the first - stage heddle and the second - stage heddle in the loom in the present invention, and the number of heddles in the first - stage heddle is variable, different types of fabric structures can be woven. Compared with the prior art that can only weave the same - type fabric structures, the applicable scenarios are wider, meeting different requirements for fabric weaving.

[0058] The present invention utilizes the principle of multiple nesting. At the rear end of the second - stage heddle, the first - stage heddle is arranged. Different - level heddles can also be arranged at the rear end of the first - stage heddle to form more - multiple nesting, providing a larger design space for pattern design, forming different product gradients, and meeting the needs of different customers.

[0059] This loom can use a jacquard harness to control each heddle wire and a rapier loom to insert the weft. The warp threads of the first - stage heddle, the second - stage heddle, and the next - level heddles form a leno weave structure with the cooperation of the weft thread.

[0060] Meanwhile, along the warp - thread traveling direction, a jacquard heddle is also arranged at the rear end of the nested heddle group 100. The warp thread passing through the nested heddle group 100 only passes through the jacquard heddle as the ground warp. Of course, the jacquard heddle can also be replaced with a heddle. When using a heddle, since only its jacquard function is used, it is substantially the same or equivalent in function to the jacquard heddle and falls within the protection scope of the jacquard heddle.

[0061] The jacquard heddle weaves a jacquard structure to form a shoe upper, and the nested twisted heddle group 100 weaves a leno structure with air permeable holes to form a shoe upper. The shoe upper forms the shape of a shoe upper.

[0062] Correspondingly, the fabric structure woven by the loom includes both leno structure and jacquard structure.

[0063] When the layout space allows, the m heddles in the first-level heddles are arranged in parallel along the weft direction; because the heddles themselves have a certain volume, when it is necessary to reduce the impact of the heddles volume, the m+1 heddles in the nested heddles group 100 are arranged in a staggered manner. More specifically, the front and rear heddles are not on the same straight line, but have a positional relationship of oblique staggered arrangement. Based on this positional relationship, the m heddles on the first-level heddles 101 can simultaneously weave the warp yarns at the front end of the first-level heddles 101. The offset of the rear heddles in the nested heddles group 100 relative to the front heddles in the weft direction allows the warp of the front heddles to pass through one side of the rear heddles, and the internal space and heddles holes of the front heddles are used to sort out the ground warp and warp of the current heddles, and the other side of the front heddles is used for the remaining warp threads to pass through for sorting the next heddles.

[0064] In order to facilitate the understanding of a multiple nested twisting method, specific parameters are added in the embodiment for explanation. Embodiment 1: like Figure 1 - Figure 2 As shown, the m value in the plurality of nested twisted heald groups 100 is the same, m is 2, 11 warp yarns are taken, and are marked with numbers 1-11 in sequence. The implementation steps S1-S4 are as follows: Figure 3 - Figure 8 , and proceed in sequence according to the figure numbers. The action of twisting the heald can also refer to the prior art CN 209555463 U.

[0065] S1: the first warp yarn of a batch of 11 warp yarns passes through the heddle hole of the second-level heddle 102 to form the first heddle warp 1, and the first heddle warp 1 no longer passes through other heddles of the nested heddle group 100; the other warp yarns pass through the inner space of the heddle of the second-level heddle 102 to form the first group of ground warps; S2: The first group of ground warps forms a new group of warp yarns at the front end of the first-level twisted heald 101. The group of warp yarns consists of 10 warp yarns, which are divided into 2 groups. One group of warp yarns enters the internal space of the first twisted heald of the first-level twisted heald 101, and the second warp yarn passes through the twisted heald hole of the first twisted heald of the first-level twisted heald 101 to form the second twisted warp 2; the other group of warp yarns enters the internal space of the second twisted heald of the first-level twisted heald 101, and the seventh warp yarn passes through the twisted heald hole of the second twisted heald of the first-level twisted heald 101 to form the third twisted warp 3. The first twisted warp 1, the second twisted warp 2, and the third twisted warp 3 no longer pass through other twisted healds of the nested twisted heald group 100, and the ground warps in the same group as the first twisted warp 1, the second twisted warp 2, and the third twisted warp 3 no longer pass through other twisted healds of the nested twisted heald group 100.

[0066] S3: Any of the heddles and ground warps in S1 and S2 form warps arranged in the same direction as those in S1 after passing through the second-level heddle 102 and the first-level heddle 101. S4: The weft yarns are woven with the warp yarns according to the requirements of the fabric texture.

[0067] Figure 1 - Figure 2 Among them, the 10 warp yarns are evenly distributed, 5 in the first heddle and 5 in the second heddle. In actual operation, only 2 warp yarns need to be left in one heddle, that is, one for forming the heddle and one for the ground warp. The distribution methods are such as 2 in the first heddle and 8 in the second heddle, or 3 in the first heddle and 7 in the second heddle, etc.

[0068] In step S1, the first heddle 1 passes through the left or right side outside the other heddles of the nested heddle group 100, and can form a shape where the first heddle 1 is located on the outermost or innermost side of the secondary twill weaving area 300. Due to the tight weaving of the warp yarns inside the secondary twill weaving area 300 layer by layer, the strength of the first heddle 1 is greatly improved, which is beneficial to maintaining the shape of the secondary twill weaving area 300 under external action.

[0069] In step S2, the second heddle 2 and the third heddle 3 pass through the left or right side outside the other heddles of the nested heddle group 100. The heddles located between the first-level heddles 101 are not adjacent. After completing the secondary twill weaving area 300, it is beneficial to separate and form the first-level twill weaving areas 200 respectively.

[0070] The corresponding formed fabric texture is as Figure 9 - Figure 13 shown.

[0071] Compared with the prior art, the leno texture of the present invention is composed of different-level twill weaving areas, which increases the pattern complexity of the leno texture. At the same time, ventilation holes of different sizes are formed between different-level twill weaving areas, and the ventilation holes of different sizes fit various parts of the human body better.

[0072] Compared with the prior art, multiple levels of heddles are set up in the nested heddle group of the present invention, and multiple heddles are set in the level heddles, which can form a multi-level twill weaving area with a larger area. Due to the complex weaving between numerous warp and weft yarns, the multi-level twill weaving area has better strength and better compressive performance; correspondingly, the ventilation holes between the multi-level twill weaving areas also become larger, greatly improving the air permeability of the leno texture.

[0073] There are also more embodiments: In the nested heddle group 100, the value of m can take any value. Then, when the number of warp yarns meets the requirements, secondary twill weaving areas 300 with different areas will be formed. The secondary twill weaving areas 300 with different areas can be combined with each other, or can be combined with the first-level twill weaving areas 200 with different areas to form more multiple twill weaving areas 400.
