A sewing method for a sock with an integrated lining

Abstract

This application provides a sewing method for an integrated sewn-on sock liner. The sock liner is knitted using a half-stitch technique and includes a main body, a small inner liner, a ribbing unit, and a sewing unit. The ribbing unit is connected to the sewing unit. The bottom edge of the small inner liner is sewn to the main body via the sewing unit. The steps include first attaching half-stitches, then knitting in the order of cast-on, small inner liner, ribbing unit, and heel, and finally undoing the half-stitches. Unlike existing technologies, this technical solution changes the position of the sewing unit, extending it along the ribbing unit and towards the bottom edge of the inner liner unit. This allows the inner liner unit to be integrally sewn to the sock liner body, eliminating the need for heat treatment to melt hot melt wire for bonding or other bonding methods. This significantly reduces the cost of manpower and material resources and improves the stability of the connection between the inner liner unit and the sock liner body.

Description

Technical Field

[0001] This application relates to the field of textile technology, specifically to a sewing method for an integrated sewn-on sock liner. Background Technology

[0002] There are many types of sock liners produced and designed, with different structures and processing methods. They come in three main specifications: single-layer, double-layer, and inner liner. Double-layer and inner liner liners must undergo heat treatment to bond the lining and the main body of the sock together after knitting. The inner liner protects the heel, making it more comfortable to wear, and can also conceal some of the weave lines on the heel, while also structurally increasing the strength of the heel.

[0003] Further information related to the above technical solutions can be found in the following documents: Patent document CN218219343 U discloses a sock with multifunctional eyelets, including an outer sock shoe, an inner sleeve unit, and a first eyelet. The outer sock shoe is integrally formed. The inner sleeve unit folds inside the outer sock shoe and fits onto it. The first eyelet protrudes from the outer sock shoe and includes a first eyelet unit and a second eyelet unit. By providing a protruding first eyelet on the outer sock shoe, and by providing first eyelet units and second eyelet units with different orientations, shoelaces can be threaded into and out of the first eyelet from different directions, allowing for free changes in the lacing method, thereby better controlling the shoelaces, improving tightness from multiple angles, and enhancing user comfort.

[0004] In the process of developing this invention, the inventors discovered the following problems with the existing technology: Currently, the main method of bonding the inner lining to the sock body involves adding hot-melt wire to the sock body and melting the hot-melt wire through heat treatment to bond the lining and the sock body together. This process is not only time-consuming and labor-intensive, but also relatively costly. Summary of the Invention

[0005] In view of the above problems, this application provides a technical solution for connecting the sock body and the inner sleeve, so as to solve the problems of high manpower and high cost in the prior art.

[0006] To achieve the above objectives, the inventor provides a sewing method for an integrated sewn-on sock liner. The sock liner is knitted using a half-needle technique. The sock liner includes a main body, a small inner sleeve, a ribbing unit, and a sewing unit, with the ribbing unit connected to the sewing unit. The bottom edge of the small inner sleeve is sewn to the main body via the sewing unit. The steps include:

[0007] Knit in the following order: beginning, inner loop, ribbing unit, and heel, then decrease with half stitches.

[0008] The half-stitch, also known as the closure stitch, comes in single-piece and double-piece types. It is used for the starting and closing of the double-layered cuff of folded socks. The double-piece half-stitch consists of two separate thin steel plates. The hook at the front end can hook the yarn to conceal the yarn arc, and the knitting needle can pass through the round hole formed in the middle to transfer loops. The heel plate can push the half-stitch forward or backward under the action of the half-stitch's triangle. The single-piece half-stitch consists of a single thin steel plate, and the knitting needle can pass through the space between the two half-stitches to complete the transfer loop.

[0009] In some embodiments, the rib unit is woven in the following order: rib, back rib back side, top rib ring, back rib front side, front rib front side, and back side.

[0010] In some embodiments, the ribbing uses a forward rotation, half-position + full-position knitting method; the back of the rear ribbing uses a forward and reverse rotation, full-position + half-position + empty stitch knitting method; the top ring of the ribbing uses a forward rotation, full-position knitting method; the front of the rear ribbing uses a forward and reverse rotation, full-position + half-position + empty stitch knitting method; and both the front and back of the front ribbing use a forward and reverse rotation, full-position + empty stitch knitting method.

[0011] In some embodiments, the stitching unit extends along the bottom edge of the ribbed unit toward the inner sleeve unit.

[0012] In some embodiments, the starting stitch is performed clockwise, with three and a half rows of full stitches and empty stitches, followed by the addition of half stitches and full stitches. The starting stitch is essential; it must be done before adding the half stitches.

[0013] In some embodiments, three rows of backflip pins are left during the closing step.

[0014] In some embodiments, the heel is woven with a plain weave.

[0015] In some embodiments, the heel uses a forward and reverse knitting pattern, with full-position weaving.

[0016] In some embodiments, the socks are woven using a single-sided circular knitting machine.

[0017] In some embodiments, the step of filling the interior of the small inner sleeve.

[0018] Unlike existing technologies, the above-mentioned technical solution changes the weaving process of the one-piece sewn sock liner. It eliminates the need for heat treatment to melt the hot melt yarn for bonding, and also eliminates the need for other bonding methods. The inner liner and the sock body are molded as one piece, making the inside of the sock liner simpler, reducing the time cost of post-processing, greatly reducing the cost of human and material resources, and improving the stability of the connection between the inner liner unit and the sock body.

[0039] Please see Figure 1 , Figure 1 This is a reverse view of an existing sock design. Most current sock types include a small inner sleeve at the heel. This inner sleeve is only attached to the cuff on one side and can be folded up and down. After knitting, these socks require manual heat treatment, typically involving using tools to melt the heat-fused fibers of the inner sleeve and bond them to the main body of the sock.

[0040] This embodiment provides a sewing method for an integrated sewn-on sock liner, using a half-needle stitch in conjunction with knitting. The steps include:

[0041] Begin with the first three and a half rows, then attach the half stitches. Knit in the order of the inner sleeve, ribbing unit, and heel, then decrease the half stitches. The inner sleeve unit and heel unit are sewn together after decreasing the half stitches.

[0042] The sprue unit is woven in the following order: sprue, back of rear sprue, top ring of sprue, front of rear sprue, front of front sprue, and back.

[0043] The ribbing uses a forward rotation, half-position + full-position knitting method; the back of the rear ribbing uses a forward and reverse rotation, full-position + half-position + empty stitch knitting method; the top ring of the ribbing uses a forward rotation, full-position knitting method; the front of the rear ribbing uses a forward and reverse rotation, full-position + half-position + empty stitch knitting method; the front and back of the front ribbing both use a forward and reverse rotation, full-position + empty stitch knitting method.

[0044] The term "knitting technique" refers to the method of creating a pattern by changing and combining the way the knitting needles appear. This combination does not necessarily have to follow a set pattern. Different patterns require different knitting techniques, which can be freely combined to produce varying effects.

[0045] The stitching unit extends along the bottom edge of the ribbed unit towards the inner sleeve unit.

[0046] The starting position is clockwise, and after three and a half rows of full stitches plus empty stitches, begin to knit with half stitches and continue knitting in full position.

[0047] After the syringe has traveled three and a half rows, the half needle emerges and hangs the yarn. At the end, leave three blank rows before withdrawing the half needle.

[0048] The heel is woven with a plain weave.

[0049] The heel uses a forward and reverse knitting method, covering the entire area.

[0050] Please see Figure 2 The sock body 1 includes a ribbed cuff unit 11 and a sewing unit 12, wherein the ribbed cuff unit 11 is connected to the sewing unit 12. A small inner sleeve 2 is disposed on the inner side of the sock body; the bottom edge of the small inner sleeve 2 is sewn to the sock body 1 through the sewing unit 12; the sewing unit 12 extends along the ribbed cuff unit 11 toward the bottom edge of the small inner sleeve 2.

[0051] The sock body 1 includes a ribbed cuff unit 11 and a sewing unit 12. The ribbed cuff unit 11 is the unit for the foot to be inserted into the shoe. The sewing unit 12 is the unit for sewing the inner sleeve 2 to the sock body 1. The sock body 1 is symmetrical about its center line.

[0052] The inner sleeve 2 is placed inside the sock body 1, and its bottom edge is connected to the sock body 1 through the sewing unit 12.

[0053] like Figure 2 As shown, the sewing unit 12 is sewn along the ribbing unit 11. When sewing reaches the small inner sleeve 2, it continues to be sewn downwards along the bottom edge of the small inner sleeve 2. The sewn-up one-piece sewn stocking is as follows: Figure 3 As shown.

[0054] Unlike existing technologies, the above-mentioned technical solution changes the weaving process of the one-piece sewn sock liner. It eliminates the need for heat treatment to melt the hot melt yarn for bonding, and also eliminates the need for other bonding methods. The inner liner and the sock body are molded as one piece, making the inside of the sock liner simpler, reducing the time cost of post-processing, greatly reducing the cost of human and material resources, and improving the stability of the connection between the inner liner unit and the sock body.

[0055] In some other embodiments, the sock body 1 includes interconnected toe unit, upper unit, midsole unit, and heel unit.

[0056] In some other embodiments, the heel is woven with a plain weave. A plain weave fabric is woven in a way that the warp and weft yarns interweave every other yarn. During the weaving process, the warp and weft yarns interweave to form parallel patterns. Plain weave fabrics are characterized by numerous interlacing points, a strong texture, a smooth surface, identical appearance on both sides, and are relatively lightweight and breathable.

[0057] The heel is made using a plain weave because the yarn on the half needle has not yet been used when the heel is being woven, so the needle cylinder cannot use more yarn to work. The plain weave method can avoid yarn tangling.

[0058] In some other embodiments, the stitching unit 12 is completely closed at the bottom or side of the inner sleeve 2 without any opening.

[0059] In some other embodiments, the process further includes filling the interior of the inner sleeve. The sewing unit 12 has an opening 13 at the bottom or side of the inner sleeve 2. The sewing unit 12 connects to the edge of the inner sleeve 2, linking the inner sleeve 2 to the stocking body 1. The sewing unit 12 has an opening 13 at the bottom or side edge of the inner sleeve 2, and the other edges of the inner sleeve 2 are sewn together normally. Specifically, the position of the opening 13 of the sewing unit 12 can be set and adjusted according to the needs of post-processing.

[0060] In some other embodiments, a filler is provided within the opening 13. Specifically, the filler can be foam. Foam is a material made by foaming plastic particles, and is simply referred to as foam. Foam is classified into PU foam, antistatic foam, conductive foam, EPE, antistatic EPE, CR, EVA, crosslinked PE, SBR, EPDM, etc. Foam is elastic, lightweight, allows for quick pressure-sensitive fixation, is easy to use, flexible, and ultra-thin. After filling the opening 13 of the sewing unit 12 with foam, the opening 13 is tied and closed, thereby achieving a soft and puffy cushioning effect at the heel.

[0061] In some other embodiments, the ribbed unit 11 is made of polyester high-elastic yarn with elastic bands. Both polyester high-elastic yarn and elastic bands have good elasticity, so this arrangement allows the ribbed area to have good stretchability and better fit the foot.

[0062] In some other embodiments, the socks are woven using a single-sided circular knitting machine. Circular knitting machines can be divided into two categories: single-sided circular knitting machines (with only a cylinder) and double-sided circular knitting machines (with both a cylinder and a dial, or two cylinders). They are typically named according to their main characteristics and the fabric structure they process. Single-sided circular knitting machines include four-needle-track machines, twill machines, jacquard machines, padding machines (commonly known as sweatshirt machines), terry machines, four-tone yarn machines, warp-winding machines, and artificial fur (pile) machines, etc. Double-sided circular knitting machines include rib knitting machines, double rib (cotton / wool) machines, multi-needle-track machines (two tracks on the upper dial and four tracks on the lower cylinder, etc.), jacquard machines, four-tone yarn machines, transfer rib knitting machines, and piecework garment machines, etc. Some circular knitting machines combine the functions of two or three single machines, expanding the range of products that can be knitted, such as jacquard four-tone yarn machines and jacquard four-tone yarn transfer machines.

[0063] In some embodiments, the single-sided circular knitting machine is a Galers sock knitting machine. The Galers sock knitting machine is the original sock knitting machine among single-sided circular knitting machines, capable of producing single / double-layer full socks, half socks, as well as sock cuffs and socks. Its principle is that the yarn enters the yarn guide through the yarn frame, the yarn guide distributes the yarn tension, then enters the lifting rod, and finally enters the inner and outer holes of a shuttle in a specific path for weaving. Structurally, the machine has four shuttle paths, each containing 1-5 shuttles. Their function is to provide yarn for weaving different parts. Each shuttle path is threaded according to the actual process sheet requirements. For example, if the process sheet requires elastic bands for the No. 1 inner hole in path 1, the corresponding position needs to be found on the machine. The corresponding cylinder has four needle selectors, each containing two needle selectors, whose function is to control the state of the knitting needles according to the program requirements. For example, if a certain step in the program requires an empty needle or a half-position needle, the selector controls the knitting needles to achieve this. The knitting needles come in different specifications, such as 120-200.

[0064] To enable readers to more intuitively understand some specific embodiments of this application, the following embodiments are also provided for reference.

[0065] In this embodiment, "forward rotation" and "forward and reverse rotation" indicate the direction of the syringe's movement. If the syringe rotates straight in one direction, it is considered forward rotation; if the syringe rotates forward a short distance and then reverses, it is considered forward and reverse rotation.

[0066] The ways in which the needle exits the needle tube (the length of the needle extending out of the needle tube) include: full position, half position, and empty position; full position is a full position needle, half position is a half position needle, and empty position is an empty needle.

[0067] The working method of the Huff needle is as follows: first, the syringe moves three and a half rows, then the Huff needle chain instruction is added to the right instruction bar, and at the end, three rows of Huff needle are left to retract.

[0068] Figure 4 This is a computer-generated knitting program diagram for existing socks. The old knitting method was: first, make a small inner liner - then attach the half stitch - knit the ribbing - finish by binding off the half stitch.

[0069] The computer-generated knitting program diagram for the one-piece sewn-on sock liner provided in this application is as follows: Figure 5 As shown. The knitting method for the one-piece sewn-in lining sock provided in this solution is as follows: start with a half stitch - knit the small inner lining - knit the ribbing - knit the heel - decrease the half stitches.

[0070] ① Beginning: Turn clockwise, complete three and a half rows with a full position and an empty needle, then begin hanging a half needle and completing the full position.

[0071] ②Inner sleeve: rotates clockwise and counterclockwise, full position, plain weave.

[0072] ③Roller opening: Forward rotation, half position + full position.

[0073] ④ Back of the spool: Forward and reverse rotation, full position + half position + empty needle.

[0074] ⑤ Rotate around the top of the auger: clockwise, move to the full position.

[0075] ⑥ Rear screw head front: forward and reverse, full position + half position + empty needle.

[0076] ⑦ Front and back of the front spool: both rotate forward and backward, with full position and empty needle.

[0077] ⑧ Heel: Turn clockwise and counterclockwise, full position, plain weave.

[0078] ⑨ End with: Huff stitch.

[0079] The working method of the Huff needle is as follows: First, the syringe moves three and a half rows, then the Huff needle chain instruction is added to the right instruction bar, and at the end, the Huff needle moves three rows and then retreats.

[0080] Finally, it should be noted that although the above embodiments have been described in the text and drawings of this application, this should not limit the scope of patent protection of this application. Any technical solutions that are based on the essential concept of this application and utilize the content described in the text and drawings of this application, resulting in equivalent structural or procedural substitutions or modifications, as well as the direct or indirect application of the technical solutions of the above embodiments to other related technical fields, are all included within the scope of patent protection of this application.
