Description

Technical Field

[0001] The invention relates to the field of textile technology, in particular to a method for preparing a creel woven twisted heald shoe upper with yarns capable of changing warp direction at will. Background Art

[0002] Woven uppers have gradually become the first choice of many professional athletes and sports enthusiasts due to their unique structural characteristics and material advantages. It is not just a kind of upper material, but also a reflection of the pursuit of a perfect balance between sports performance, comfort and durability. Through precise weaving technology, woven uppers can accurately control the density, elasticity and breathability of the uppers, ensuring that they provide the wearer with just the right support, protection and comfort in different sports scenarios.

[0003] Chinese patent application No. 202111484349.3 discloses a production process for shoe fabrics, including the preparation of fabric grey cloth and fabric finishing; the fabric grey cloth includes a transparent horizontal stripe part and a bark-like pattern part; the warp yarn is a transparent nylon monofilament, and the weft yarn includes a transparent weft yarn and a polyester FDY twisted yarn with different colors; the transparent horizontal stripe part is interwoven by the warp yarn and the transparent weft yarn; the bark-like pattern part is interwoven by the warp yarn and the polyester FDY twisted yarn of different colors according to the weft quadruple organization, and the fabric finishing refers to treating the fabric grey cloth in a tension-free state and an environment of 120-160℃ for 10-30min. The fabric grey cloth is heat-set, and combined with the different shrinkage properties of nylon and polyester, the transparent horizontal stripe part and the bark-like pattern part have a large difference in weft density, which, combined with the bark wrinkle pattern, exacerbates the visual effect of fabric shrinkage and wrinkling. However, the fabric has poor lightness and breathability, and the fabric has relatively poor wear resistance and folding resistance.

[0004] Chinese patent application No. 202323254259.2 discloses a local elastic woven shoe material fabric, including a shoe waist area, a shoe bladder area, a shoe tongue area, a back waist area and a shoe heel area; the shoe waist area and the shoe heel area are inelastic areas, and at least one area of ​​the shoe bladder area, the shoe tongue area and the back waist area is an elastic area; the weft yarn includes elastic yarn and hot-melt yarn. The shoe bladder area, the shoe tongue area and the back waist area set in the shoe material fabric are elastic through the selection of yarn. In the inelastic area of ​​the shoe material fabric, the hot-melt yarn and the elastic yarn woven by the common shed mouth will melt the hot-melt yarn after heat treatment, and adhere to the elastic yarn, so that the elastic yarn cannot be elastically stretched, so that the woven fabric in this area is not elastic. Thereby, the shoes prepared by the shoe material fabric are easier to wear. However, when weaving the shoe fabric, if you want to achieve a rich three-dimensional effect with jacquard structure, you need to change the warp design, but the warp yarn cannot be changed at will, so it takes a lot of time and material costs. Summary of the invention

[0005] Therefore, in response to the above-mentioned problems, the present invention provides a method for preparing a woven twisted shoe upper with a creel in which the yarn in the warp direction can be changed at will, so as to solve the problems that the existing woven shoe uppers have poor lightweight and breathable effects, and the wear resistance and folding resistance of the fabric are relatively poor, and the yarn in the warp direction cannot be changed at will when weaving the shoe upper.

[0006] To achieve the above object, the present invention adopts the following technical solutions:

[0007] A method for preparing a creel woven twisted heald shoe upper with yarns that can be changed arbitrarily in the warp direction, comprising the following steps:

[0008] S1. Preparation of raw materials: 0.12mmPTPEE glossy fold-resistant yarn, 0.20mmTPU high and low temperature composite low elastic monofilament, 0.20mmTPU glossy high elastic monofilament, polyester DTY167dtex / 36F semi-gloss high elastic yarn;

[0009] S2, weaving: using a creel weaving twisted heald machine to weave raw yarn into a grey cloth, the grey cloth includes a polygonal woven mesh structure and a raised texture structure, the creel weaving twisted heald upper is woven from warp yarns and weft yarns, and the warp yarns include twisted warps and ground warps;

[0010] S3, pre-forming the grey cloth, and then washing it with water, setting it by stretching, inspecting it, packaging it and putting it into storage to obtain a creel woven twisted heald shoe upper;

[0011] The grey fabric is woven by twisted heald weaving and partial twisted heald weaving. The twisted heald weaving is as follows: the twist is controlled by the jacquard needle holes on both sides of the twisted needle. For the left jacquard, the twist needle is on the left side of the twisted needle; for the right jacquard, the twist needle is on the right side of the twisted needle. The left and right jacquard makes the twisted needle flip left and right and fixed by weft yarn.

[0012] The local twisted heald weaving is as follows: the twisted needles and the weft yarns are interwoven perpendicularly to each other, and the twisted needles are hidden on the reverse side so that the twisted needles are not exposed on the reverse side and are in a non-twisted state;

[0013] The left jacquard is specifically as follows: when the left jacquard is needed, the jacquard needle hole located on the left side of the twisted needle will lift the corresponding warp (including the twisted warp and the ground warp); the twisted needle is on the left side of the twisted needle, so the twisted warp will be turned to the left under the action of the left jacquard needle hole; at the same time, the weft yarn is introduced and interwoven with the turned twisted warp to form a specific pattern;

[0014] The right jacquard is specifically as follows: when the right jacquard is needed, the jacquard needle hole located on the right side of the twisted needle will lift the corresponding warp thread; the twisted needle is on the right side of the twisted needle, so the twisted warp will be turned to the right under the action of the jacquard needle hole on the right side; similarly, the weft yarn is introduced and interwoven with the turned twisted warp to form the pattern on the other side;

[0015] The combined use of left and right jacquards can achieve the left and right flipping and fixing of the twisted warp; through different jacquard needle hole arrangements and combinations, complex and varied patterns can be created; in this process, the twisted warp is firmly fixed in the fabric under the interweaving action of the weft yarn, forming a unique twisted structure.

[0016] Furthermore, the weft yarn includes a first weft yarn, a second weft yarn, a third weft yarn, a fourth weft yarn, a fifth weft yarn and a sixth weft yarn; the fifth weft yarn is a 0.20mmTPU bright high-elastic monofilament, and the first weft yarn, the second weft yarn, the third weft yarn, the fourth weft yarn and the sixth weft yarn are all polyester DTY167dtex / 36F semi-bright high-elastic yarn; the ground warp includes a first ground warp and a second ground warp, and the twisted warp and the ground warp required to form a yarn hole are defined as a twist group, and there is a twisted warp and a first ground warp in one twist group, that is, the twisted warp: the first ground warp = 1:1, and the interweaving method of one twist group is one twist, and the second ground warp is 5 0.12mmPTPEE bright folding-resistant yarns; the twisted warp and the first ground warp are 0.20mmTPU high and low temperature composite low-elastic monofilament.

[0017] Furthermore, the warp density of the creel-woven twisted heddle upper is 52 strands / cm, and the finished product density is 17 shuttles / cm.

[0018] Furthermore, the weaving method of the polygonal woven mesh structure is as follows: the twisted warp and the ground warp are inserted into a reed together; two or more of the twisted groups are staggered and the yarn structure and the rib structure are twisted at the same time, that is, after one or more weft yarns are woven into a certain horizontal row, the yarn structure is twisted once, and at the same time, after three or more odd-numbered weft yarns are woven into the next horizontal row, the rib structure is twisted once.

[0019] Furthermore, the weaving method of the raised texture structure is: utilizing the controllable design of the floating length of the weft yarn on the surface of the fabric body, so that the weft structure points are continuously arranged on the surface of the fabric body, and when shaping, the part of the area is exposed to the raised texture on the surface under the shrinkage effect of the TPU high-low temperature composite low-elastic monofilament;

[0020] The floating length refers to the continuous uninterwoven part formed by the yarn on the fabric surface; the raw materials of the TPU high-low temperature composite low-elastic monofilament and TPU glossy high-elastic monofilament are thermoplastic polyurethane. During the shaping process, the TPU material will shrink due to the action of heat and external force. This shrinkage will cause the part of the fabric in contact with the TPU to be squeezed and stretched, thereby forming a convex or concave texture effect on the fabric surface.

[0021] Furthermore, the TPU high-low temperature composite low-elastic monofilament is a skin-core structure, and the skin-core structure includes an inner core layer and an outer skin layer, the melting point of the core layer is 190°C, and the melting point of the skin layer is 170°C; when the setting temperature is higher than 170°C, the core layer does not melt, the skin layer melts and solidifies, bonding the woven warp and weft points, and fixing the mesh shape at the same time. TPU is transparent, soft and fold-resistant, which can not only retain the original color of the fabric to the maximum extent, but also enhance the strength and wear resistance of the fabric. The specification of the high-low temperature composite low-elastic monofilament is 400D, and there will be no yarn breakage even if it is twisted continuously for multiple times.

[0022] Furthermore, the specification of the 0.20mmTPU high-low temperature composite low-elastic monofilament is 400D; the specification of the 0.20mmTPU glossy high-elastic monofilament is 400D.

[0023] Furthermore, the presetting temperature is set at 150-180°C, the fabric speed is set at 15 yards / min, the tentering setting temperature is set at 140-160°C, and the fabric speed is set at 125 yards / min.

[0024] Furthermore, the number of warp yarns of the twisted warp is 2568, and the number of warp yarns of the ground warp is 6430; the number of shuttles of the first weft yarn, the second weft yarn, the third weft yarn, and the fourth weft yarn is 539, the number of shuttles of the fifth weft yarn is 179, and the number of shuttles of the sixth weft yarn is 40.

[0025] Furthermore, the colors of the twisted warp, ground warp and fifth weft yarn are all transparent.

[0026] By adopting the above technical solution, the beneficial effects of the present invention are:

[0027] 1. The raw materials of TPU high-low temperature composite low-elastic monofilament and TPU glossy high-elastic monofilament are thermoplastic polyurethane. During the shaping process, the TPU material will shrink due to the action of heat and external force. This shrinkage will cause the part of the fabric in contact with TPU to be squeezed and stretched, thus forming a convex or concave texture effect on the fabric surface.

[0028] 2. TPU high-low temperature composite low-elastic monofilament is a skin-core structure, with 190℃ high melting point TPU as the core layer and 170℃ low melting point TPU as the skin layer. When the setting temperature is higher than 170℃, the core layer does not melt, the skin layer melts and solidifies, bonding the woven warp and weft points and fixing the mesh shape at the same time. TPU is transparent, soft and fold-resistant, which can not only retain the original color of the fabric to the maximum extent, but also enhance the fabric strength and wear resistance.

[0029] 3. The warp yarn is twisted and woven by a twisted heald weaving method. The warp yarn is a transparent TPU high-low temperature composite low-elastic monofilament. The ratio of the twisted warp to the ground warp in a twisted group is 1:1. The two are twisted with each other to make the surface present clear and evenly distributed yarn holes. Two or more twisted groups are staggered and the yarn structure and the grommets are twisted at the same time, breaking through the square shape of the traditional shuttle-woven yarn holes, so that the mesh shape is diamond or hexagonal, just like a knitted mesh. Compared with traditional shuttle-woven twisted palm products, while having the woven twisted palm partial opening to meet the breathable function of the upper, due to the participation of different specifications of yarns in the warp creel, it can increase the wrapping capacity by 30% and reduce the product weight by 20%.

[0030] 4. The pre-setting process is high temperature and fast, and the finished product is set at a slightly lower temperature and slow speed, so that the surface of the finished product is stable during setting, and the internal structure of the raw material is not damaged, which prolongs the service life of the fabric. The fabric is woven from colored yarn and does not require post-dyeing treatment. It only needs to be washed in open width, and the fabric is degreased and modified with additives.

The specification of the high-low temperature composite low-elastic monofilament is 400D. Even if it is twisted continuously for multiple times, there will be no yarn breakage.

[0043] (2) Weaving

[0044] refer to Figure 2 , using a creel weaving twisted heald machine to weave raw yarn into a grey cloth, the creel weaving twisted heald upper 3 includes a polygonal woven mesh structure 4 and a raised texture structure 5, the grey cloth is woven from warp yarns and weft yarns, and the warp yarns include a twisted warp 11 and a ground warp 12;

[0045] (2-1)Reference Figure 3 The weft yarns include a first weft yarn 21, a second weft yarn 22, a third weft yarn 23, a fourth weft yarn 24, a fifth weft yarn 25 and a sixth weft yarn 26; the fifth weft yarn 25 is a 0.20 mm TPU glossy high elastic monofilament, the first weft yarn 21, the second weft yarn 22, the third weft yarn 23, the fourth weft yarn 24 and the sixth weft yarn 26 are all polyester DTY167dtex / 36F semi-gloss high elastic yarn; the ground warp 12 includes a first ground warp 121 and a second ground warp 122, it is defined that the twisted warp 11 and the ground warp 12 required to form a yarn hole are a twist group, and there is a twisted warp 11 and a first ground warp 121 in one twist group, that is, the twisted warp 11: the first ground warp 121 = 1:1, and the interlacing mode of one twist group is one twist one, and the second ground warp 122 is 5 0.12mmPTPEE glossy and fold-resistant yarns; the twisted warp 11 and the first ground warp 121 are 0.20mmTPU high-low temperature composite low-elastic monofilaments;

[0046] The number of warp yarns of the hank warp is 2568, and the number of warp yarns of the ground warp is 6430; the number of shuttle yarns of the first weft yarn, the second weft yarn, the third weft yarn, and the fourth weft yarn is 539, the number of shuttle yarns of the fifth weft yarn is 179, and the number of shuttle yarns of the sixth weft yarn is 40; the colors of the hank warp, the ground warp, and the fifth weft yarn are all transparent;

[0047] (2-2) The grey fabric is woven by two methods: twisted heald weaving and partial twisted heald weaving. The twisted heald weaving is as follows: the twist is controlled by the jacquard needle holes on both sides of the twisted needle. In the left jacquard, the twisted needle is on the left side of the twisted needle; in the right jacquard, the twisted needle is on the right side of the twisted needle. The left and right jacquard makes the twisted needle flip left and right and fixed by the weft yarn;

[0048] The local twisted heald weaving is as follows: the twisted needles and the weft yarns are interwoven perpendicularly to each other, and the twisted needles are hidden on the reverse side so that the twisted needles are not exposed on the reverse side and are in a non-twisted state;

[0049] The left jacquard is specifically as follows: when the left jacquard is needed, the jacquard needle hole located on the left side of the twisted needle will lift the corresponding warp (including the twisted warp and the ground warp); the twisted needle is on the left side of the twisted needle, so the twisted warp will be turned to the left under the action of the left jacquard needle hole; at the same time, the weft yarn is introduced and interwoven with the turned twisted warp to form a specific pattern;

[0050] The right jacquard is specifically as follows: when the right jacquard is needed, the jacquard needle hole located on the right side of the twisted needle will lift the corresponding warp thread; the twisted needle is on the right side of the twisted needle, so the twisted warp will be turned to the right under the action of the jacquard needle hole on the right side; similarly, the weft yarn is introduced and interwoven with the turned twisted warp to form the pattern on the other side;

[0051] The combination of left and right jacquard can realize the left and right flipping and fixing of the twisted warp; through different jacquard needle hole arrangements and combinations, complex and varied patterns can be created; in this process, the twisted warp is firmly fixed in the fabric under the interweaving of the weft yarn, forming a unique twisted structure;

[0052] (2-3)Reference Figure 4 The weaving method of the polygonal woven mesh structure is as follows: the twisted warp 11 and the second ground warp 122 are inserted into a reed together; the two twisted groups are staggered and the yarn structure and the rib structure are twisted at the same time, that is, after five first weft yarns 21 are woven into a certain row, the yarn structure is twisted once, and at the same time, after five first weft yarns 21 are woven into the next row, the rib structure is twisted once;

[0053] (2-4)Reference Figure 5The weaving method of the raised texture structure is as follows: utilizing the controllable design of the floating length of the weft yarn on the surface of the fabric body to continuously arrange the weft structure points on the surface of the fabric body, and during shaping, under the shrinkage of the TPU high-low temperature composite low-elastic monofilament, the raised texture is revealed on the surface of the partial area; the weaving yarn of the raised texture structure includes: a first weft yarn 21, a fifth weft yarn 25, and a sixth weft yarn 26;

[0054] The floating length refers to the continuous uninterwoven part formed by the yarn on the fabric surface; the raw materials of the TPU high-low temperature composite low-elastic monofilament and TPU glossy high-elastic monofilament are thermoplastic polyurethane. During the shaping process, the TPU material will shrink due to the action of heat and external force. This shrinkage will cause the part of the fabric in contact with the TPU to be squeezed and stretched, thereby forming a convex or concave texture effect on the fabric surface;

[0055] (3) Pre-order type

[0056] The grey cloth is subjected to a pre-setting treatment, and the pre-setting machine adopts the EAG-2000-CBR-0 Taiwan-based Shengligen setting machine. This setting machine adopts high-temperature hot air setting technology, so that the hot air acts evenly on the front and back sides of the fabric. When the temperature in the closed oven of the setting machine is higher than the glass transition temperature of the fabric, the polymer inside the fiber raw material is reorganized, thereby changing the surface size of the fabric. The grey cloth is fed into the setting machine along the weaving direction, and firstly, the setting size of the fabric is stretched or shrunk by the overfeed roller device and the needle clip chain stretching device, and then it is set through multiple dry heat closed oven devices. The set fabric is cooled and the pre-setting is completed. The pre-setting temperature is set at 150°C, and the input fabric speed is set at 15 yards / min, so that the TPU cortex can be fully melted without affecting the setting effect of the cloth surface;

[0057] (4) Open-width washing

[0058] Dye auxiliaries are used for open-width water washing. The formula of dye auxiliaries includes: 3% refining agent, 4% degreasing agent 119, 2% degreasing agent Z83, 4% chelating dispersant, and the balance is water. The open-width water washing speed is 12 yards / min. At 60°C, the refining agent is first added to box one and stirred to mix evenly; then the temperature is raised to 80°C, and degreasing agent Z83 and chelating dispersant are added to remove impurities; then after hot boiling in boxes three and four, the cloth is transferred to box five, and the temperature is lowered to 60°C for washing; the temperature in box six is ​​lowered to room temperature, and water is squeezed and dried, and finally the cloth is discharged; the refining agent and degreasing agent 119 are used to remove impurities, stains and oil stains on the surface of the fabric, and the chelating dispersant is used to prevent the generation of metal ion precipitation from affecting the color of the fabric, thereby improving the water washing effect;

[0059] (5) Tentering and shaping

[0060] The principle of tentering setting is basically the same as that of pre-setting, and the most important difference lies in the setting temperature and setting time. The setting machine uses EAG-2300-CBR-0 Taiwan's Sang Li Gen setting machine. The tentering setting temperature is set at 140℃ to prevent TPU from melting again, and the input speed of the fabric is set at 12 yards / min.

[0061] (6) Then, the inspection, packaging and warehousing processes are carried out to obtain the creel woven tangle upper, wherein the density of the creel woven tangle upper is 52 strands / cm, and the finished product density is 17 strands / cm.

[0062] Table 1 is the test results of the example products.

[0063] Table 1

[0064]

[0065]

[0066]

[0067] It can be seen from Table 1 that the color fastness of the fabric prepared by the technical solution, such as resistance to dry and wet friction, sweat and soap washing, all reach above level 4-5, indicating that the fabric has good color fastness; the bursting strength of the fabric reaches 2.10×10 3 kPa, high tear strength, indicating that the fabric strength is very good. The fabric wear resistance reaches level 4, and the folding resistance at room temperature and low temperature is intact without damage, indicating that the fabric has very good wear and folding resistance. All the test indicators of the fabric meet the requirements, so the fabric quality meets the predetermined design requirements of the project.

[0068] Although the present invention has been specifically shown and described in conjunction with the preferred embodiments, it should be understood by those skilled in the art that various changes may be made to the present invention in form and details without departing from the spirit and scope of the present invention as defined by the appended claims, all of which are within the scope of protection of the present invention.
