Description

Multi-nested twist weaving loom, method, fabric structure and shoe upper Technical Field

[0001] The present invention relates to the field of weaving technology, in particular to a multiple nested twist weaving loom, a method, a fabric structure and a shoe upper. Background Art

[0002] A loom is a device that crosses warp and weft yarns to weave fabric. When the weft yarn is passed through, if a part of the warp yarn is lifted, an opening is formed between the warp yarns, and the weft yarn passes through the opening, thereby weaving the fabric.

[0003] The fabric structures woven by different types of looms include leno weave and jacquard weave: leno weave refers to a fabric structure composed of two systems of warp yarns, ground and twill, and one system of weft yarns, in which the warp yarns are twisted together. The eyelets formed by the twisted warp yarns on the leno fabric are called twill eyes; jacquard weave refers to the pattern or design formed by the warp yarns or weft yarns floating or sinking on the surface of the fabric or interweaving according to regular requirements.

[0004] Previous looms were able to combine leno weave and jacquard weave to form new fabrics. The leno weave in such fabrics was often in a single form, and the several breathable holes formed on the leno weave were of the same size. For example, there is a Korean patent with application number 201580060919.2, entitled "Loom for weaving heterogeneous fabrics, uppers and shoes woven therewith"; and a Chinese patent with application number 201710228075.9, entitled "A jacquard machine-woven holed fabric and its weaving method."

[0005] As mentioned above, conventional looms only used a single-level leash heddle combined with a jacquard heddle to weave fabrics. It was impossible to combine a higher-level leash heddle with a jacquard heddle to weave new fabrics, nor was it possible to combine leash heddles of different levels to weave fabrics containing different types of leno weaves. This further resulted in the monotony of the fabric composition.

[0006] However, when the multi-nested twist loom and weaving method of the present invention are used, when the fabric structure contains different gauze structures, it can also be combined with the jacquard structure, which can form air holes of different sizes and increase the breathability of the fabric; and it is no longer limited to the shape of the fabric structure on the fabric, and is suitable for various fabrics such as shoe uppers, and can be made into clothing such as shoe uppers.

[0073] The above technical features can be combined with each other as long as they do not conflict with each other.

[0074] The beneficial effects of the present invention are:

[0075] 1. Compared with the prior art, the present invention has multiple levels of twisted healds in the nested twisted heald group, and multiple twisted healds are set up in the first-level twisted heald, which can form a multi-level twisted weaving area with a larger area. Due to the complex weaving between the numerous warp and weft threads, the multi-level twisted weaving area has better strength and better compression resistance; accordingly, the air pores between the multi-level twisted weaving areas are also enlarged, greatly improving the air permeability of the gauze structure.

[0076] 2. Compared with the prior art, the gauze fabric of the present invention is composed of different levels of twisted weaving areas, which increases the pattern complexity of the gauze fabric. At the same time, air holes of different sizes are formed between the different levels of twisted weaving areas. The air holes of different sizes fit various parts of the human body better and meet the different ventilation needs of different parts.

[0077] 3. The twisted warp of the present invention passes through the left or right side of the outside of other twisted healds in the nested twisted heald group, so that the twisted warp is located at the outermost or innermost side of the secondary twisted weaving area. The warp yarns inside the secondary twisted weaving area are tightly woven layer by layer, and the strength of the twisted warp is greatly improved, which is conducive to maintaining the shape of the secondary twisted weaving area under external influences.

[0078] 4. The m twirl heddles in the first-level twirl heddle of the present invention are arranged in parallel along the weft direction when the arrangement space permits; since the twirl heddle itself has a certain volume, when it is necessary to reduce the impact of the twirl heddle volume, the m twirl heddles are staggered. More specifically, the front and rear twirl heddles are not on the same straight line, but have a positional relationship of oblique staggered arrangement. Based on this positional relationship, the m twirl heddles on the first-level twirl heddle can weave the warp yarns at the front end of the first-level twirl heddle at the same time, thereby improving the weaving efficiency.

[0079] 5. The present invention arranges first-level and second-level heddles in the loom, and the number of heddles in the first-level heddles is variable, so that different types of fabric structures can be weaved. Compared with the existing technology that can only weave the same type of fabric structure, the applicable scenarios are wider and the different needs of fabric weaving are met.

[0080] 6. The present invention adopts the principle of multiple nesting, and can also set the next level of heddle at the rear end of the first level of heddle to form more nesting, providing a larger design space for pattern design, forming different product gradients, and meeting the needs of different customers.

[0081] 7. The warp of the first-stage twisted weaving area of ​​the present invention can be twisted with a single or multiple twisted weaving areas of the next stage to form different types of fabric structures, thereby enriching the diversity of the fabric structure.

[0096] DETAILED DESCRIPTION

[0097] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are merely for explaining the present invention and are not intended to limit the present invention. In addition, the technical features involved in the various embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other. The present invention is further described in detail below with reference to specific embodiments.

[0098] The direction of travel of the warp yarn in the loom is shown in Figure 1.

[0099] As shown in Figures 1 and 2, a multiple nested leash loom includes a plurality of nested leash heddle groups 100, which are arranged in sequence along the weft direction on the loom. The nested leash heddle groups 100 include a second-stage leash heddle 102 at the front end in the warp yarn travel direction and a first-stage leash heddle 101 at the rear end.

[0100] The second-stage leash 102 is composed of a single leash, and the first-stage leash 101 is composed of m leash, where m is an integer greater than 1.

[0101] The second-level leash heddle 102 is used to form a leno weave of twisting multiple ground warps, and the first-level leash heddle 101 is used to form a leno weave containing m twist groups from the multiple ground warps from the second-level leash heddle 102.

[0102] As can be understood from Figures 1-2, the warp yarns pass through the heddle holes of the second-level heddle 102 to form twisted warps and no longer pass through other heddles in the nested heddle group 100. The warp yarns pass through the internal space of the second-level heddle 102 to form ground warps; the ground warps passing through the second-level heddle 102 form warp yarns at the front end of the first-level heddle 101. The warp yarns are divided into m groups, at least one warp yarn passes through the heddle holes of each group of heddles as twisted warps, and at least one warp yarn passes through the internal space of each group of heddles as ground warps. Each group of twisted warps no longer passes through other heddles of the first-level heddle 101, and each group of ground warps no longer passes through other heddles of the first-level heddle 101. The above-mentioned internal space is in the shape of an inverted A.

[0103] Furthermore, it is not limited to two levels of twisted healds, and the nested twisted heald group 100 also includes a lower-level twisted heald of the first-level twisted heald arranged at the rear end of the first-level twisted heald 101 along the warp yarn travel direction, and the lower-level twisted heald of the first-level twisted heald is composed of x twisted healds, x is an integer greater than 1, and the lower-level twisted heald of the first-level twisted heald is used to form multiple ground warps from at least one of the m twisted healds of the first-level twisted heald 101 into a gauze structure containing x twist groups.

[0104] Of course, along the traveling direction of the warp yarn, other levels of heddles can be set at the rear end of the lower heddle to meet the weaving requirements of different fabric tissues.

[0105] The present invention arranges first-level and second-level heddles in the loom, and the number of heddles in the first-level heddles is variable, so that different types of fabric structures can be weaved. Compared with the existing technology that can only weave the same type of fabric structure, the present invention has a wider range of applicable scenarios and meets the different needs of fabric weaving.

[0106] The present invention utilizes the principle of multiple nesting, and sets the first-level heddle at the rear end of the second-level heddle. Different levels of heddle can also be set at the rear end of the first-level heddle to form more nesting, which provides a larger design space for pattern design, forms different product gradients, and meets the needs of different customers.

[0107] The loom can use a jacquard faucet to control each heald and a rapier loom to insert the weft, and the warp yarns of the first-level heald, the second-level heald and the next-level heald are used to form a gauze structure in cooperation with the weft yarns.

[0108] At the same time, a jacquard heddle is also arranged in the direction of warp travel and at the rear end of the nested leash heddle group 100. The warp yarns passing through the nested leash heddle group 100 only serve as ground warps and pass through the jacquard heddle. Of course, the jacquard heddle can also be replaced by a leash heddle. When a leash heddle is used, it only uses its jacquard function and is essentially functionally the same as or equivalent to a jacquard heddle, falling within the scope of protection of a jacquard heddle.

[0109] The jacquard heddle weaves a jacquard structure for the shoe upper, and the nested thong heddle group 100 weaves a leno structure with air permeable holes for the shoe upper. The shoe upper forms the shape of a shoe upper.

[0110] Accordingly, the fabric structure woven by the loom includes both leno structure and jacquard structure.

[0111] 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 causes the warp yarns of the front heddles to pass through the outside of one side of the rear heddles. The internal space and heddle hole of the front heddles are used to sort out the ground warp and warp yarns of the current heddles, and the other side of the front heddles is used for the remaining warp yarns to pass through for sorting the next heddles.

[0112] In order to facilitate the understanding of a multiple nested twisting method, specific parameters are added in the embodiment for explanation. Example

[0113] As shown in Figures 1-2, several nested leash heddle groups 100 have the same m value of 2, and 11 warp yarns are taken, which are sequentially numbered 1-11. Steps S1-S4 are implemented as shown in Figures 3-8, and are performed sequentially according to the figure numbers. The leash heddle operation can also refer to the prior art CN 209555463 U.

[0114] 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 warp 1, and the first warp 1 does not pass through other heddles in the nested heddle group 100; the other warp yarns pass through the inner space of the heddle hole of the second-level heddle 102 to form the first group of ground warps;

[0115] S2: The first group of ground warps forms a new group of warp yarns at the front end of the first-level heddle 101. The group of warp yarns consists of 10 warp yarns, and the 10 warp yarns are divided into 2 groups. One group of warp yarns enters the internal space of the first heddle of the first-level heddle 101, and the second warp yarn passes through the heddle hole of the first heddle of the first-level heddle 101 to form the second warp 2; the other group of warp yarns enters the internal space of the second heddle of the first-level heddle 101, and the 7th warp yarn passes through the heddle hole of the second heddle of the first-level heddle 101 to form the third warp 3. The first warp 1, the second warp 2, and the third warp 3 no longer pass through other heddles of this nested heddle group 100, and the ground warps in the same group as the first warp 1, the second warp 2, and the third warp 3 no longer pass through other heddles of this nested heddle group 100.

[0116] S3: Any leash and ground warp in S1 and S2 form warp yarns arranged in the same direction as in S1 after passing through the second-stage leash heddle 102 and the first-stage leash heddle 101;

[0117] S4: The weft yarns are woven with the warp yarns according to the requirements of the fabric structure.

[0118] The 10 warp yarns in Figures 1 and 2 are evenly distributed, with 5 yarns in the first thong and 5 yarns in the second thong. In actual operation, only 2 warp yarns need to be left in one thong, that is, one for forming the thong and one for the ground warp. The distribution method can be such as 2 yarns in the first thong and 8 yarns in the second thong, or 3 yarns in the first thong and 7 yarns in the second thong, etc.

[0119] In step S1, the first warp 1 passes through the left or right side of the outside of other warps in the nested warp group 100, so that the first warp 1 is located at the outermost or innermost side of the secondary weaving area 300. The warp yarns inside the secondary weaving area 300 are tightly woven layer by layer, and the strength of the first warp 1 is greatly improved, which is conducive to maintaining the shape of the secondary weaving area 300 under external influence.

[0120] In step S2, the second and third twisted warps 2 and 3 pass through the left or right side of the outside of other twisted warps in the nested twisted warp group 100. The twisted warps between the first-level twisted warps 101 are not adjacent. After completing the secondary twisted weaving area 300, it is beneficial to separate them into the primary twisted weaving area 200.

[0121] The corresponding fabric structures are shown in Figures 9 to 13.

[0122] Compared with the prior art, the gauze fabric of the present invention is composed of twisted woven areas of different levels, which increases the pattern complexity of the gauze fabric. At the same time, air holes of different sizes are formed between the twisted woven areas of different levels. The air holes of different sizes can better fit various parts of the human body.
