Description

Technical Field

[0001] The present invention relates to the field of textiles, and in particular to a loom and a weaving method for weaving irregular openwork woven shoe uppers. Background Art

[0002] Traditional two-way woven fabrics are made by interweaving warp and weft yarns on a loom. The longitudinal yarns parallel to the selvedge in the fabric are called warp yarns, and the transverse yarns perpendicular to the selvedge are called weft yarns. The intersection of the warp and weft yarns is called the weave point. After decades of development in the textile industry, woven fabrics have become the main material for shoe uppers. However, the warp and weft yarns of woven fabrics are interwoven with each other, and the gaps between the yarns are small, so woven fabrics are less breathable than knitted fabrics.

[0003] Existing woven fabrics have already encountered the problem of using a twisted heddle structure to weave a gauze structure to improve the air permeability of the woven fabric. The main principle of the gauze structure is to twist the warp yarns left and right to each other so that the warp yarns in the twist group occupy a larger space, while separating the adjacent twist groups. The twisting also separates the adjacent weft yarns and prevents them from being closely attached, forming yarn holes to improve the ventilation effect of the fabric. However, the gauze structure requires multiple twisted heddle structures to be installed on the loom, and the weaving process is relatively cumbersome. At the same time, because the twisting of the yarn will form concave and convex points at the tissue points, it affects the wearing comfort. Therefore, there is an urgent need for an openwork woven fabric that does not require twisting of the warp yarns and can increase the pores at the tissue points. Therefore, the applicant proposes a loom and weaving method for weaving irregular openwork tissue woven shoe uppers. Summary of the Invention

[0004] The invention provides a loom and a weaving method for weaving irregular open-hole woven shoe uppers, aiming to improve the technical problems of the leno weave of existing woven fabrics, such as complicated weaving and poor wearing comfort.

[0005] A loom for weaving irregular openwork woven shoe uppers, comprising: a warp let-off mechanism, an opening mechanism, a weft insertion mechanism, a beating-up mechanism, and a curling mechanism, wherein the opening mechanism comprises: a first harness group, which is arranged in a row of at least two metal harnesses, A second harness group, which is configured in a row of at least two metal harnesses, The first harness group and the second harness group are arranged in sequence along the traveling direction of the weft yarn; The loom also includes a jacquard mechanism, which controls the metal heddles to move up and down independently according to the set design; The metal shedders of the first shedder group include a first metal shedder and a second metal shedder. The first metal shedder is controlled to be lifted and the second metal shedder is controlled to be sunk to form a shed. Two or more weft yarns are introduced into the shed, and the warp and weft yarns are beaten to form an openwork structure.

[0006] Furthermore, the width of the loom determines the number of rows of harness groups. A rapier loom generally has 25 to 30 rows of harness groups.

[0007] Furthermore, the upper end of the metal heald is connected to the jacquard mechanism, and the lower end of the metal heald is connected to the loom body through a spring. A brown eye is provided in the middle of the metal heald for the warp yarn to pass through. The metal heald independently moves up and down alternately to lift part of the warp yarn and sink the other part of the warp yarn to form a shed. The first heald group includes at least two metal healds, and the second heald group includes at least two metal healds.

[0008] Furthermore, the metal shedders of the second shedder group include a third metal shedder and a fourth metal shedder. The third metal shedder is controlled to be lifted and the fourth metal shedder is controlled to be sunken to form a shed and a weft yarn is introduced. The warp and weft yarns are beaten to form a common texture.

[0009] Furthermore, the warp let-off mechanism includes an upper warp beam and a lower warp beam, and the upper warp beam and the lower warp beam are respectively wound with warp yarns.

[0010] Furthermore, the weft insertion mechanism comprises a rapier arrow, and the weft yarn is introduced into the shed by the rapier arrow.

[0011] Furthermore, the beating-up mechanism includes a reed, which pushes the weft yarn toward the cloth fell to complete the interweaving of the warp and weft yarns.

[0012] The present invention also provides a method for weaving an irregular open-hole woven shoe upper. The weaving steps are as follows using the above-mentioned loom for weaving an irregular open-hole woven shoe upper: S1. The warp yarns of the upper and lower warp beams are passed through the eyelets of the metal sheaths according to pre-designed requirements. Each warp yarn is controlled by a corresponding metal sheath. After the warp yarns pass through the eyelets, two or more warp yarns to be bundled are passed through the same reed dent of the steel reed. Therefore, when a reed dent has a warp yarn inserted into the bundle, the adjacent reed dent does not have a warp yarn inserted into it, forming an empty reed. S2. When weaving an openwork weave, the first metal shedding of the first shedding group is controlled to be lifted and the second metal shedding is controlled to be sunk to form a shed, and two or more weft yarns are introduced into the shed. The bundled warp yarns on the same reed tooth are bundled with the multiple weft yarns in the same shed to form an openwork weave with holes between the weaving points. S3, when weaving a normal texture, the third metal shedding of the adjacent second shedding group is lifted and the fourth metal shedding is sunk to form a shed and introduce a weft yarn. At this time, the warp and weft yarns are not gathered into bundles, forming a normal texture; S4. Repeat steps 2 and 3 to weave a predetermined openwork texture and a normal texture in a predetermined design area to obtain a woven upper fabric in which the openwork texture and the normal texture are woven as one. According to the pre-designed design, the woven upper fabric can be woven into more than three shoe uppers along the weft direction. The woven upper fabric can be cut into pieces along the shape of the shoe upper by a laser cutting machine. The woven upper pieces can be used for the next step of shoe production.

[0013] Preferably, in step S3, the common texture is one or more of a plain weave texture area, a twill weave texture area, a satin weave texture area, a plain weave variation texture area, a twill weave variation texture area, and a satin weave variation texture area.

[0014] Preferably, the number of weft yarns introduced into the shed of the first and second shedding groups is variable. When one weft yarn is introduced into the shed of the first shedding group, a common texture structure is formed, and when two or more weft yarns are introduced into the shed of the second shedding group, an openwork structure is formed.

[0015] Preferably, the metal sheddles of the first sheddling group and the metal sheddles of the second sheddling group are closely arranged in sequence along the traveling direction of the weft yarn, so the openwork tissue and the ordinary grain tissue are woven continuously at one time, and the dividing line between the openwork tissue and the ordinary grain tissue can form an irregular curve. Beneficial effects:

[0016] The present invention adopts a design in which the first and second harness groups are sequentially arranged along the traveling direction of the weft yarns, and cooperates with a weaving method to pass two or more warp yarns to be bundled into the same reed dent, so that the bundled warp yarns of the same reed dent and the multiple weft yarns of the same shed are gathered into a bundle, and an openwork weave with holes between the weave points is woven, so that the woven shoe upper includes the openwork weave; At the same time, the metal sheddles are closely arranged and the jacquard mechanism can independently control each metal shedd to make alternating up and down movements according to the set design, so that the openwork tissue and the ordinary grain tissue can be woven continuously at one time. At the same time, the dividing line between the openwork tissue and the ordinary grain tissue can form an irregular curve, which not only adds a sense of pattern to the fabric, but also improves its permeability, thereby solving the problem of poor air permeability of woven fabrics.

DETAILED DESCRIPTION

[0020] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the invention for which protection is sought, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0021] Example 1, please refer to Figures 1 to 3 A first embodiment of the present invention provides a loom for weaving irregular openwork woven shoe uppers, comprising: a warp let-off mechanism 1, an opening mechanism 2, a weft insertion mechanism 3, a beating-up mechanism 4, a curling mechanism 5 and a jacquard mechanism 6; the opening mechanism 2 includes 30 rows of shedding groups, one row of shedding groups is composed of two metal shedding groups 21, and the shedding groups are arranged in sequence along the traveling direction of the weft yarn 8; the jacquard mechanism 6 independently controls the metal shedding groups 21 to independently perform up and down alternating movements according to the set design.

[0022] Specifically, the upper end of the metal shepherd 21 is connected to the jacquard mechanism 6, and the lower end of the metal shepherd 21 is connected to the loom body through a spring. A brown eye 213 is provided in the middle of the metal shepherd 21 for the warp yarn 7 to pass through. The metal shepherd 21 independently performs an up and down alternating movement to lift a part of the warp yarn 7 and sink the other part of the warp yarn 7 to form a shed.

[0023] In addition, the warp let-off mechanism 1 includes an upper warp beam 101 and a lower warp beam 102 , and the warp yarns 7 are wound around the upper warp beam 101 and the lower warp beam 102 , respectively.

[0024] At the same time, the weft insertion mechanism 3 includes a rapier arrow, and the weft yarn 8 is introduced into the shed by the rapier arrow. The beating-up mechanism 4 includes a reed 401, and the reed 401 pushes the weft yarn 8 toward the weaving opening to complete the interweaving of the warp and weft yarns.

[0025] Specifically, see Figures 4 to 6 , using the above loom, the weaving steps of weaving the irregular openwork woven shoe upper in this embodiment are as follows: S1. The warp yarns 7 of the upper warp beam 101 and the lower warp beam 102 are respectively passed through the eyelets 213 of the metal sheaths 21 according to pre-designed requirements. One warp yarn 7 is controlled by a corresponding metal sheath 21. After the warp yarn 7 passes through the eyelets 213, two or more warp yarns 7 to be bundled are passed through the same reed dent of the reed 401. Therefore, when a reed dent has a warp yarn passed through it, the adjacent reed dent does not pass the warp yarn, forming an empty reed. S2. When weaving an openwork stitch 901, the first metal shedding 211 of the shedding group is controlled to rise and the second metal shedding 212 is controlled to sink to form a shed, and three weft yarns 8 are introduced into the shed. The bundled warp yarns 7 on the same reed dent and the multiple weft yarns 8 at the same shed are gathered into a bundle to form an openwork stitch 901 with holes between the stitch points. S3, when weaving the common texture 902, the third metal shedding 221 of the adjacent shedding group is lifted and the fourth metal shedding 222 is sunk to form a shed and introduce a weft yarn 8. At this time, the warp and weft yarns are not gathered into bundles, forming the common texture 902. The 30 harness groups on the loom weave an openwork stitch 901 and a normal texture stitch 902 in the area according to a predetermined design. At the same time, the number of weft yarns 8 introduced into the shed of the harness group can be changed. When one weft yarn 8 is introduced into the shed of the first harness group, a normal texture stitch 902 is formed, and when three weft yarns 8 are introduced into the shed of the second harness group, an openwork stitch 901 is formed. S4. Repeat steps 2 and 3 to weave a predetermined openwork texture 901 and a normal texture texture 902 in a predetermined design area to obtain a woven upper fabric 9 in which the openwork texture 901 and the normal texture texture 902 are woven as one. According to the pre-designed method, in this embodiment, the woven upper fabric 9 can be used to weave three uppers at a time along the weft direction. The woven upper fabric 9 is then cut into pieces along the shape of the upper by a laser cutting machine. The pieces of woven upper can be used for the next step of shoe production.

[0026] In step S3 of this embodiment, the common texture 902 is a plain weave texture area.

[0027] See also Figures 7 to 9 In this embodiment, the openwork tissue 901 and the ordinary texture tissue 902 of the woven shoe upper are woven continuously as one; Specific as Figure 8 As shown, the first warp yarn 701, the third warp yarn 703, the fourth warp yarn 704, the sixth warp yarn 706 and the weft yarn 8 have more interlacing points, while the second warp yarn 702, the fifth warp yarn 705 and the weft yarn 8 sandwiched in the middle have fewer interlacing points and longer float lengths. This configuration separates the third warp yarn 703 and the fourth warp yarn 704 from each other, and at the same time separates the third weft yarn 803 and the fourth weft yarn 804 from each other, thereby making the first warp yarn 701, the second warp yarn 702, the third warp yarn 703 and the fifth warp yarn 705 separate from each other. The fourth warp yarn 704, the fifth warp yarn 705, and the sixth warp yarn 706 are respectively gathered into bundles, and the first weft yarn 801, the second weft yarn 802, the third weft yarn 803 and the fourth weft yarn 804, the fifth weft yarn 805, and the sixth weft yarn 806 are respectively gathered into bundles, so that a hole is formed between the third warp yarn 703 and the fourth warp yarn 704, and a hole is formed between the third weft yarn 803 and the fourth weft yarn 804, so that holes can be formed between the yarn organization points without twisting the warp yarns, thereby improving the permeability of the fabric.

[0028] Example 2, reference Figure 10 It is a structural diagram provided by the second embodiment of the present invention. The structure of the second embodiment is substantially the same as that of the first embodiment. The difference lies in that when weaving the openwork structure 901, the number of weft yarns 8 introduced into the shed is five. In this embodiment, because the number of weft yarns 8 introduced into the shed is five, the bundled warp yarns 7 on the same reed tooth and the five weft yarns 8 in the same shed are more closely bunched together, so the holes between the tissue points are larger than the holes in the first embodiment where three weft yarns are introduced, and the permeability is better.

[0029] The implementation principle and technical effects provided by the second embodiment of the present invention are the same as those of the first embodiment. For the sake of brief description, for matters not mentioned in this embodiment, reference may be made to the corresponding contents in the first embodiment.

[0030] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
