Description

Technical Field

[0001] This utility model relates to the field of fabrics, and more specifically, to a deformation-resistant fabric. Background Technology

[0002] Currently, mattress fabrics are usually made by plain knitting fibers. However, because of the plain knitting structure, the loops formed by the fabric fibers are more prone to unraveling. As a result, the fabric cannot form more support points inside, causing long-term friction between the fibers and the human body and long-term pressure. This causes the fabric to gradually lose its original shape and elasticity, thus deforming the mattress fabric. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a deformation-resistant fabric. The fabric is formed by fiber weaving into a single-layer structure, and rectangular groove units and rectangular protrusion units are formed on the single-layer structure. The alternating arrangement of the groove units and protrusion units makes the fabric form a multi-point support structure and restricts the degree of fiber movement in multiple directions, thereby reducing the friction between fibers and increasing the dispersion of pressure on the fabric surface. The support strips and protrusion units in the groove units reduce the overall deformation of the fabric.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: an anti-deformation fabric, comprising a groove unit and a protrusion unit, wherein the groove unit is rectangular, and the two short sides of the groove unit are connected to the protrusion unit, with four protrusion units forming a group, the groove unit being located at the center of the protrusion unit, and support strips being connected at the two diagonals of the groove unit, and the two support strips located within the groove unit being arranged in a crisscross pattern.

[0006] The present invention is further configured such that the ratio of the length D of the groove unit to the width C of the groove unit is 1.8:1 to 2.5:1.

[0007] The present invention is further configured such that, along the fabric width direction, the stagger distance between the two groove units in the lateral direction is 1 / 2 to 1 / 4 of the length D of the groove unit.

[0008] The present invention is further configured such that the length E of the protruding unit is equal to the width C of the groove unit, and the width F of the protruding unit is 1 / 6 of the length D of the groove unit.

[0009] The present invention is further configured such that a height difference H is formed between the protruding unit and the groove unit, and a height difference L is formed between the support strip and the groove unit, wherein the ratio of the height difference H to the height difference L is 3:1 to 5:1.

[0010] The present invention is further configured such that the fabric is woven in a 22-way loop as one cycle, a 14-way loop as one cycle to form the groove unit, a 4-way loop as one cycle to form the protrusion unit, and a 4-way loop as one cycle to form the support strip.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figure 1 — Figure 4 As shown, this embodiment discloses an anti-deformation fabric, including groove units 30 and raised units 40. The fabric is woven in 22-way coil rows as one cycle, with 14-way coil rows forming the groove unit 30, 4-way coil rows forming the raised unit 40, and 4-way coil rows forming the support strip 301. In one weave cycle, the 1st, 2nd, 3rd, 4th, 5th, 10th, 11th, 12th, 13th, 14th, 15th, 16th, 21st, and 22nd coil rows form the groove unit 30, and each of the 1st, 2nd, 3rd, 4th, 5th, 10th, 11th, 12th, 13th, 14th, 15th, 16th, 21st, and 22nd coil rows contains 3 coils. Knit the stitches into a circle, then knit 3 stitches to create a float, repeating this cycle. For rows 1, 2, 3, 4, 5, 10, 11, 12, 13, 14, 15, 16, 21, and 22, the knit stitches in adjacent rows form circles symmetrically with the float stitches. Rows 6, 7, 17, and 18 form raised units 40. In each row of rows 6, 7, 17, and 18, the purl stitches form a circle, then knit 3 stitches into a circle, then knit 3 stitches to create a float, repeating this cycle. The knit stitches in rows 6 and 7, and rows 17 and 18, form circles symmetrically with the float stitches. (Refer to...) Figure 4 Because the loop positions of the 6th and 7th loop rows are the same as those of the 1st, 3rd, 5th, 11th, 13th, 15th, and 21st loop rows, and the loop positions of the 17th and 18th loop rows are the same as those of the 2nd, 4th, 10th, 12th, 14th, 16th, and 22nd loop rows, the fabric knitting forms a three-layer structure. At the same time, along the length of the fabric, the groove units 30 and the raised units 40 are arranged alternately. Along the width of the fabric, two adjacent groove units 30 are arranged in an alternating pattern, and two adjacent raised units 40 are arranged in an alternating pattern. This creates multi-point support for the fabric, thereby increasing the structural stability of the fabric.

[0022] Because the groove unit 30 has 14 rows of stitches as a cycle, but each row of stitches has 6 knitting needles and 6 purlting needles, the groove unit 30 is rectangular. Since the knitting needle loop positions of the 6th and 7th rows of stitches are the same as those of the 1st, 3rd, 5th, 11th, 13th, 15th, and 21st rows of stitches, and the knitting needle loop positions of the 17th and 18th rows of stitches are the same as those of the 2nd, 4th, 10th, 12th, 14th, 16th, and 22nd rows of stitches, the length E of the protruding unit 40 is equal to the width C of the groove unit 30. This allows the two short sides of the groove unit 30 to be connected to the protruding unit 40, and... Figure 1 The fabric consists of four raised units 40 as a group, with the grooved unit 30 located at the center of the raised unit 40. This causes the raised unit 40 to create resistance to the grooved unit 30 at the four sides of the grooved unit 30. Therefore, when the fabric is subjected to external stress, the raised unit 40 and the grooved unit 30 form an interaction force in multiple directions, thereby restricting the movement of the fibers inside the fabric in multiple directions. This not only disperses the stress on the fabric surface but also reduces the friction between the fibers, thus preventing the fibers inside the fabric from becoming uncoordinated due to external stress, thereby increasing the fabric's resistance to deformation.

[0023] The 8th, 9th, 19th, and 20th row stitches form support strip 301. The 8th row stitch consists of 3 knit stitches forming a loop, with 3 knit stitches forming a float, but no purl stitches. Similarly, the 9th row stitch also consists of 3 knit stitches forming a loop, with 3 knit stitches forming a float, but all purl stitches are knitted. The position of the 3 knit stitches forming a loop in the 9th row stitch is symmetrical to that of the 8th and 10th row stitches. Likewise, the 19th row stitch consists of 3 knit stitches forming a loop, with 3 knit stitches forming a float, but no purl stitches. The 20th row stitch also consists of 3 knit stitches forming a loop, with 3 knit stitches forming a float, but all purl stitches are knitted. The position of the 3 knit stitches forming a loop in the 20th row stitch is symmetrical to that of the 19th and 21st row stitches. Furthermore, the 8th, 9th, 19th, and 20th row stitches form a loop. The 9th and 20th coil rows are located in the middle of the coil rows of the groove unit 30 and below the protruding unit 40. Therefore, the 8th, 9th, 19th and 20th coil rows are woven to form two support strips 301, and the two support strips 301 are arranged in a cross pattern within the groove unit 30. Thus, the support strips 301 are connected to the two diagonals of the groove unit 30. This allows the groove unit 30 and the support strips 301 to share the external stress while the support strips 301 reinforce the support of the groove unit 30, thereby reducing the fabric from loosening and deforming due to excessive external stress. Furthermore, the support strips 301 reduce the stress borne by a single groove unit 30, allowing the external stress to be dispersed and transmitted to the surrounding area, thereby reducing local deformation of the fabric.

[0024] Because the groove unit 30 is rectangular, and the ratio of the length D to the width C of the groove unit 30 is 1.8:1 to 2.5:1, preferably 2:1, this is because when a person lies on the fabric, the pressure exerted by the person on the fabric along its length is greater than the pressure exerted by the person on the fabric along its width. Therefore, the groove unit 30 distributes external stress more evenly when subjected to external stress. Simultaneously, the groove unit 30 can better bear and distribute body weight along its length, thus maintaining the flatness and stability of the fabric surface. Furthermore, because the two transverse groove units 30 are staggered and extend along the width of the fabric... In terms of direction, the staggered distance between the two transverse groove units 30 is 1 / 2 to 1 / 4 of the length D of the groove unit 30. Preferably, the staggered distance between the two transverse groove units 30 is 1 / 2 of the length D of the groove unit 30. Therefore, when the fabric is subjected to external stress, the movement of the fibers inside the fabric will be limited to a certain range, thereby avoiding deformation caused by excessive stretching. And when the external stress is removed, because the width F of the protruding unit 40 is 1 / 6 of the length D of the groove unit 30, the protruding unit 40 is sandwiched between the staggered groove units 30. Therefore, under the interaction force, the fibers inside the fabric will quickly return to their original state, thereby reducing the possibility of deformation.

[0025] Because the grooved unit 30 is only woven into loops on the lower needle, while the four loops of the raised unit 40 are woven into loops on both the upper and lower needles, a height difference H is formed between the raised unit 40 and the grooved unit 30. Since two of the four loops forming the support strip 301 are woven into loops only on the lower needle, and the other two loops are woven into loops on both the upper and lower needles, a height difference L is formed between the support strip 301 and the grooved unit 30. The ratio of height difference H to height difference L is 3:1 to 5:1, preferably 3.5:1. This creates multi-point support and gradient stress distribution in the fabric. Through the combined action of multiple support points, the fabric interacts internally, and the gradient stress distribution reduces excessive local pressure, thus reducing fabric deformation due to uneven stress. Furthermore, the height difference between the raised unit 40 and the support strip 301 forms a three-dimensional structure, providing additional support to the fabric and allowing the fabric surface to maintain its shape and structure stably.

[0026] In the selection of fabric raw materials, the 1st, 2nd, 3rd, 4th, 5th, 10th, 11th, 12th, 13th, 14th, 15th, 16th, 21st, and 22nd coil rows use 100D polyester low-elasticity yarn to reduce the deformation inside the fibers of the groove unit 30. The 6th, 7th, 17th, and 18th coil rows use spandex core-spun yarn to increase the elasticity of the raised unit 40, thereby adding cushioning for the groove unit 30 and reducing the deformation of the groove unit 30. The 8th, 9th, 19th, and 20th coil rows use 60D double-ply yarn. Because the fibers of the support strip 301 are the thickest, it can effectively stabilize the structure of the groove unit 30, thereby improving the overall structural stability of the fabric.
