A woven tape with automatic recovery function after folding and its production process

Abstract

This invention relates to the field of webbing manufacturing technology and discloses a webbing with an automatic recovery function after folding and its manufacturing process. It includes two main parts: ordinary warp yarns and a grooved section with several sets of ordinary weft yarns distributed on the outside. In this invention, the grooved section and the main parts employ different weaving methods. By using fine warp yarns and ordinary warp and weft yarns of different grades, the grooved section is made thinner, forming sections of different widths. The narrower section makes it easier for the webbing to fold along the grooved section, allowing it to quickly rebound when there is no external pressure. The wider section ensures proper stress distribution during wear, without affecting comfort, thus improving comfort. It also facilitates rapid rebound after folding in the narrower section without the need for manual smoothing. The grooved section provides better breathability, sweat-wicking, and quick-drying properties.

Description

Technical Field

[0001] This invention relates to the field of webbing manufacturing technology, specifically to a webbing with an automatic recovery function after folding and its manufacturing process. Background Technology

[0002] Waistbands are typically wide fabrics woven from two or more layers of warp and weft yarns, possessing a certain thickness. The webbing itself (including wide jacquard webbing, which only features flat or raised patterns in certain areas without altering the webbing's structure) is a planar structure, allowing for a relatively uniform weave. Obese individuals or those with large bellies often experience discomfort when wearing wide waistbands (e.g., wider than 30mm) as the webbing tends to fold and flip when sitting down, and doesn't easily return to its original shape when standing up. Existing improvements to waistbands typically use thicker yarns to increase the overall thickness of the webbing, thus improving its resilience.

[0003] The existing technology has the following disadvantages:

[0004] Firstly, when standing, the wide waistband is completely close to the body. However, when sitting, it will be squeezed by the belly and body, causing the waistband to fold down and flip. When standing up, the folded and flipped part may automatically return to its original state when the fold width is small. However, when the fold width is large, the wide waistband is difficult to return to its original state automatically. At this time, it needs to be smoothed out manually, which may cause discomfort in some public places.

[0005] Secondly, the thicker yarn material commonly used in the market increases the stiffness and fold resistance of the belt, but it is difficult to restore after being folded, and the thick belt affects the comfort and also increases the production cost.

[0006] Thirdly, stiff and rigid yarns can be used on the market, which enhances the resistance to bending and folding recovery of the belt. However, due to the limitations of the yarn material itself, the recovery ability is poor, and the stiff belt reduces the wearer's comfort.

[0007] Fourthly, the webbing is generally denser and thicker than the fabric, which makes it less breathable and sweat-wicking, especially during exercise, resulting in a stuffy feeling. Summary of the Invention

[0008] (a) Technical problems to be solved

[0009] In view of the above-mentioned shortcomings of the prior art, the present invention provides a webbing with automatic recovery function after folding and its manufacturing process, which can effectively solve the problems of the prior art.

[0010] (II) Technical Solution

[0011] To achieve the above objectives, the present invention provides the following technical solution:

[0012] This invention discloses a webbing with an automatic recovery function after folding and its manufacturing process, comprising two main parts, wherein several sets of elastic warp yarns are distributed on the outer walls of both ends of the main parts, and recessed stripes are distributed between the elastic warp yarns;

[0013] The main body contains eight ordinary warp yarns, and the eight ordinary warp yarns are divided into two groups and distributed alternately.

[0014] The concave section contains eight fine warp yarns;

[0015] The outer surface of the ordinary warp yarns and the concave stripe portion is provided with several sets of ordinary weft yarns.

[0016] To elaborate further, one end of the main body has a set of elastic warp yarns distributed on its outer wall, and the other end of the main body has two sets of elastic warp yarns distributed thereon. The two sets of main body parts and elastic warp yarns are mirror-symmetrical during weaving.

[0017] To go further, the recessed stripe portion is located between two sets of elastic warp yarns distributed on the outside of the main body portion.

[0018] To go further, the ordinary weft yarn is interwoven perpendicularly with the ordinary warp yarn and the concave stripe portion.

[0019] To elaborate further, the main body consists of upper layers of ordinary warp and weft yarns woven in an orderly alternation, with the ordinary warp yarns positioned above three ordinary weft yarns and then below the next ordinary weft yarn. The main body also includes lower layers of ordinary warp and weft yarns woven in an orderly alternation, with the ordinary warp yarns positioned above the next ordinary weft yarn and then below three ordinary weft yarns.

[0020] To elaborate further, the elastic warp yarns and ordinary weft yarns are woven in an orderly alternation, with the elastic warp yarns positioned above one ordinary weft yarn and the elastic warp yarns positioned below the next ordinary weft yarn.

[0021] To elaborate further, the fine warp yarns and ordinary weft yarns are woven in an orderly alternation, with the fine warp yarns positioned above one ordinary weft yarn and then the fine warp yarns positioned below the next ordinary weft yarn.

[0022] Furthermore, the fine warp yarn can be denier yarn.

[0023] Furthermore, the ordinary warp yarn can be 70 denier yarn, and the ordinary weft yarn can be 150 denier yarn.

[0024] To elaborate further, the process operation flow is as follows:

[0025] S1. Material preparation for ordinary warp yarns, ordinary weft yarns, elastic warp yarns, and fine warp yarns;

[0026] S2. Depending on whether there is a color requirement, select ordinary warp yarns, ordinary weft yarns, and fine warp yarns for dyeing and color-changing operations.

[0027] S3. Wind the ordinary warp yarn, ordinary weft yarn, and fine warp yarn onto the winding machine to remove weak points and yarn defects in the ordinary warp yarn, ordinary weft yarn, and fine warp yarn.

[0028] S4. Ordinary warp yarns, ordinary weft yarns, elastic warp yarns, and fine warp yarns are wound parallel and evenly on the warp beam at a certain length;

[0029] S5. Pass the ordinary warp yarns, elastic warp yarns, and fine warp yarns on the warp beam through the heddle wires and reed in the order shown in the heddle pattern, and then place the stop warp piece;

[0030] S6. The ribbon weaving machine, according to the structural diagram, controls the up and down movement of the heddles by the pattern chain or the generation of electronic pattern plates, interweaves ordinary warp yarns and ordinary weft yarns to form the main body containing two layers of face yarn and base yarn, and interweaves fine warp yarns and ordinary weft yarns to form the concave stripe part.

[0031] S7. The main body, elastic warp yarns, and concave stripe sections are woven and dyed to form a webbing;

[0032] S8. Test the mechanical properties, wash fastness, color fastness, shrinkage rate, etc. of the webbing as required, and inspect the appearance and dimensions of the webbing.

[0033] S9. Pack the inspected and qualified webbing into the warehouse according to the requirements.

[0034] (III) Beneficial Effects

[0035] The technical solution provided by this invention has the following advantages compared with known public technologies:

[0036] In this invention, the concave strip portion and the main body portion employ different weaving methods. By using fine warp yarns and ordinary warp yarns and ordinary weft yarns of different grades, the concave strip portion is made thinner, forming a concave strip portion that divides the webbing into sections of different widths. The narrower section makes it easier for the webbing to fold along the concave strip portion, allowing it to quickly rebound when there is no external pressure. The wider section of the webbing ensures proper stress distribution during wear without affecting comfort, thus improving comfort. It also facilitates the rapid rebound of the webbing after folding in the narrower section without the need for manual smoothing. The concave strip portion provides the webbing with better breathability, sweat-wicking, and quick-drying properties. Attached Figure Description

[0043] The present invention will be further described below with reference to embodiments.

[0044] Example

[0045] This embodiment describes a webbing with an automatic recovery function after folding and its manufacturing process, such as... Figure 1-2 As shown, it includes two main body parts 1. Several sets of elastic warp yarns 4 are distributed on the outer walls of both ends of the main body parts 1, and concave stripes 6 are distributed between the elastic warp yarns 4.

[0046] The main body 1 contains eight ordinary warp yarns 2, and the eight ordinary warp yarns 2 are divided into two groups and distributed alternately. The ordinary warp yarns 2 and ordinary weft yarns 3 in the upper layer of the main body 1 are woven in an orderly alternation with the ordinary warp yarns 2 above the three ordinary weft yarns 3 and then the ordinary warp yarns 2 below the next ordinary weft yarn 3. The ordinary warp yarns 2 and ordinary weft yarns 3 in the lower layer of the main body 1 are woven in an orderly alternation with the ordinary warp yarns 2 above the next ordinary weft yarn 3 and then the ordinary weft yarns 3 below the three ordinary weft yarns 3.

[0047] The concave section 6 contains eight fine warp yarns;

[0048] Several sets of ordinary weft yarns 3 are distributed on the outside of the ordinary warp yarn 2 and the concave stripe portion 6.

[0049] like Figure 1-2 As shown, one set of elastic warp yarns 4 is distributed on the outer wall of one end of the main body 1, and two sets of elastic warp yarns 4 are distributed on the other end of the main body 1. The two sets of main body 1 and elastic warp yarns 4 are mirror-symmetrical during weaving. The concave stripe 6 is located between the two sets of elastic warp yarns 4 distributed on the outside of the main body 1. The ordinary weft yarn 3 interweaves perpendicularly with the ordinary warp yarn 2 and the concave stripe 6. The elastic warp yarns 4 and ordinary weft yarns 3 are woven in an orderly alternation, with the elastic warp yarn 4 above one ordinary weft yarn 3 and then below the next ordinary weft yarn 3. The fine warp yarns and ordinary weft yarns 3 are woven in an orderly alternation, with the fine warp yarn above one ordinary weft yarn 3 and then below the next ordinary weft yarn 3. The ordinary warp yarns 2, elastic warp yarns 4, and fine warp yarns and ordinary weft yarns 3 follow the following pattern during weaving: Figure 1 The diagram shows the organizational structure.

[0050] like Figure 1-2 As shown, the process operation flow is as follows:

[0051] Preparation of materials for S1, ordinary warp yarn, 2, ordinary weft yarn, 3, elastic warp yarn, and fine warp yarn;

[0052] S2. Depending on whether there is a color requirement, selectively perform yarn dyeing and color-changing operations on ordinary warp yarn 2, ordinary weft yarn 3 and fine warp yarn;

[0053] S3. Wind ordinary warp yarn 2, ordinary weft yarn 3 and fine warp yarn onto the winding machine to remove weak points and yarn defects in ordinary warp yarn 2, ordinary weft yarn 3 and fine warp yarn;

[0054] S4. Ordinary warp yarn 2, ordinary weft yarn 3, elastic warp yarn 4 and fine warp yarn are wound parallel and evenly on the warp beam at a certain length;

[0055] S5. Pass the ordinary warp yarn 2, elastic warp yarn 4 and fine warp yarn on the warp beam through the heddle wires and reed in the order of the heddle threading diagram, and then place the stop warp piece;

[0056] S6. According to the structural diagram, the ribbon loom controls the heddle wires to move up and down by using a pattern chain or generating an electronic pattern plate. Ordinary warp yarns 2 and ordinary weft yarns 3 are interwoven to form the main body 1, which includes two layers of face yarn and base yarn. Fine warp yarns and ordinary weft yarns 3 are interwoven to form the concave stripe part 6.

[0057] S7. The main body 1, elastic warp yarns 4 and concave stripe part 6 are woven and dyed to form a webbing 5;

[0058] S8. Test the mechanical properties, wash fastness, color fastness, shrinkage rate, etc. of the webbing 5 as required, and inspect the appearance and dimensions of the webbing 5.

[0059] S9. Pack the qualified webbing 5 into the warehouse according to the requirements.

[0060] In summary, please refer to the following when weaving: Figure 1 As shown, the horizontal numbers 1 to 30 represent warp, and the vertical numbers 1 to 8 represent weft. Then, the horizontal numbers 2 to 9 represent eight ordinary warp yarns. The eight warp yarns are grouped into the upper layer as the second, fourth, sixth, and eighth warp yarns, and into the lower layer as the third, fifth, seventh, and ninth warp yarns. Figure 1 The black frame indicates that the ordinary warp yarn 2, elastic warp yarn 4, or fine warp yarn is located above the ordinary weft yarn 3, while the white frame indicates that the ordinary warp yarn 2, elastic warp yarn 4, or fine warp yarn is located below the ordinary weft yarn 3. This results in the main body 1 having a double-layer structure after weaving, while the concave stripe portion 6 has a single-layer structure. Since the fine warp yarn can be 40 denier, the ordinary warp yarn 2 uses 70 denier, and the ordinary weft yarn 3 uses 150 denier, the concave stripe portion 6 and the main body 1 use different weaving methods, and the fine warp yarn can be of different grades than the ordinary warp yarn 2 and ordinary weft yarn 3, allowing the concave stripe portion to be thinner. The fine warp yarn forming the concave stripe portion 6 divides the webbing 5 into sections of different widths. The narrower section makes it easier for the webbing 5 to fold along the concave stripe portion 6. When the webbing 5 is not subjected to external force... It can quickly rebound when squeezed; the wider part of the webbing 5 can ensure the stress distribution of the webbing 5 when worn without affecting comfort. In actual production, the number of fine warp yarns contained in the concave part 6 can be changed according to the needs of different widths to control the overall foldability and resilience of the webbing 5, which improves the comfort of wearing the webbing. It is easy for the narrower part of the webbing 5 to quickly rebound after being folded without the influence of external force, without the need to manually smooth the webbing 5. The concave part 6 contained in the webbing 5 makes the webbing 5 have better breathability, sweat wicking and quick-drying effect. It should be noted that even if the fine warp yarn and the ordinary warp yarn 2 and ordinary weft yarn 3 use the same specification of yarn, the concave part can still be formed. However, if the fine warp yarn and the ordinary warp yarn 2 and ordinary weft yarn 3 use different types of yarn, the concave part formed can be thinner.

[0061] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
