Abstract
Description
Technical Field
[0001] The utility model relates to the field of textiles, and more specifically to a high-elasticity breathable fabric. Background Art
[0002] Elastic fabrics currently on the market generally have elasticity only in a single direction or in several directions, but have poor elasticity in other directions, and the elasticity uniformity is not ideal. In addition, many elastic fabrics reduce the breathability of the fabrics while increasing the elasticity. Therefore, existing fabrics have the problems of poor elasticity, unsatisfactory elasticity uniformity, and poor breathability. Utility Model Content
[0003] The purpose of the utility model is to overcome the deficiencies of the above-mentioned prior art and provide a highly elastic breathable fabric, which realizes the elasticity of the fabric and continuously maintains the elasticity of the fabric through a composite structure, improves the elasticity of the fabric through elastic fibers, and increases the breathability of the fabric by forming air holes through the structure, so that the fabric can maintain its elasticity while also increasing its breathability.
[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:
[0005] The utility model discloses a high-elastic breathable fabric. The front coil row and the back coil row of the fabric are alternately arranged in a 4:4 combination. The first needle, the second needle, the third needle and the fourth needle in the first coil row are upper needles and are in a back coil state. The fifth needle, the sixth needle, the seventh needle and the eighth needle are lower needles and are in a front coil state. The second coil row, the third coil row and the fourth coil row are all distributed in accordance with the first coil row. The first needle, the second needle, the third needle and the fourth needle in the fifth coil row are lower needles and are in a front coil state. The fifth needle, the sixth needle, the seventh needle and the eighth needle are upper needles and are in a back coil state. The sixth coil row, the seventh coil row and the eighth coil row are all distributed in accordance with the fifth coil row. The coil arrangement of the first four coil rows and the coil arrangement of the last four coil rows are opposite to each other so as to form a concave and convex square block.
[0006] Furthermore, the coil of the 5th needle and the coil of the 4th needle in the second row of coils of the fabric are combined to form a double coil at the position of the 4th needle to form a breathing hole at the position of the 5th needle, and the coil of the 4th needle and the coil of the 5th needle in the sixth row of coils are combined to form a double coil at the position of the 5th needle to form a breathing hole at the position of the 4th needle.
[0007] Furthermore, the area of the square block is 0.64mm^2-4mm^2.
[0008] Furthermore, the fabric is woven by nylon core-spun yarn of 44.4dtex-77.7dtex, and the core yarn of the nylon core-spun yarn is spandex yarn.
[0009] Furthermore, the number of knitting needles of the fabric is 32 inches / 24 needles to 32 inches / 32 needles.
[0010] Furthermore, the fabric has a weaving weight of 95 g / m^2-120 g / m^2.
[0011] The beneficial effects of the utility model are:
[0012] By weaving the composite tissue, the elastic tissue is used to form concave and convex square blocks on the elastic surface, which not only improves the fabric but also improves the structural stability of the fabric elasticity, allowing the fabric to continue to maintain its elasticity. Breathable holes are formed on the breathable surface through the transfer tissue to improve the breathability of the fabric. The two tissues are woven at the same time and combined with elastic fibers to steadily improve the elasticity of the fabric while maintaining the breathability of the fabric. The extensibility of the fabric largely meets the needs of different body shapes, giving users more choices while also giving users better comfort. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0017] like Figure 1—2 shows a highly elastic breathable fabric, which is interwoven by alternating front coil rows and back coil rows in a 4:4 combination. The 1st, 2nd, 3rd and 4th needles in the first coil row are upper needles, which are in a back coil state, and the 5th, 6th, 7th and 8th needles are lower needles, which are in a front coil state. The second, third and fourth coil rows are all distributed consistently with the first coil row. The 1st, 2nd, 3rd and 4th needles in the fifth coil row are lower needles, which are in a front coil state, and the 5th, 6th, 7th and 8th needles are upper needles, which are in a back coil state. The sixth, seventh and eighth coil rows are all distributed consistently with the fifth coil row.
[0018] The 1st, 2nd, 3rd and 4th needles in the first four rows of coils form a reverse row of coils, and the 5th, 6th, 7th and 8th needles form a front row of coils. The 1st, 2nd, 3rd and 4th needles in the last four rows of coils form a front row of coils, and the 5th, 6th, 7th and 8th needles in the last four rows of coils form a reverse row of coils. Therefore, with four rows of coils as a cycle, the front coils and the reverse coils appear alternately in eight rows of coils, and with 4 needles as a cycle, the front coils and the reverse coils appear alternately in eight longitudinal rows.
[0019] Reference Figure 1 The fabric is woven by connecting the front coil and the back coil through the coil column. Because the front coil row and the back coil row are not in the same plane, the arc of the front coil row is tilted backward and the arc of the back coil row is tilted forward under the action of yarn bending. The arc of the coil is convex on both the front and back sides of the fabric, and the coil column is concave. The fabric is woven in a 4:4 coil combination arrangement configuration in the transverse direction. The arc of the coil in the first four back coil rows is convex on the back, and the arc of the coil in the second four front coil rows is convex on the front, so as to form an interlacing cycle. The front coil row and the back coil row are both four-way coil arc convex, and the four-way coil arc in the middle interval is not convex, so that longitudinal contraction is formed between adjacent convex arcs. When the fabric is stretched longitudinally, the longitudinally contracted arc is pulled apart from the middle interval. When the longitudinal stretching force is lost, the longitudinal contraction returns to the original position, thereby making the fabric rich in longitudinal elasticity.
[0020] The fabric is also arranged in a 4:4 coil combination in the longitudinal direction. The loops of the first 4 needles in the back coil longitudinal row are protruding on the back, and the loops of the coils in the next four front coil longitudinal rows are protruding on the front, forming an interlaced cycle. The front coil longitudinal row and the back coil longitudinal row both have 4 needles for the coil arcs to protrude, and the 4 needles in the middle interval are not protruding, so that lateral contraction is formed between adjacent protruding loops. When the fabric is stretched laterally, the laterally contracted loops are pulled apart from the middle interval. When the lateral stretching force is lost, the loops shrink laterally back to their original positions, thereby making the fabric rich in lateral elasticity.
[0021] Reference Figure 2 The first four rows of coils and the first four needles are the back coils, and the coil arcs protrude on the back to form a concave square block 500. The last four rows of coils and the first four needles are the front coils, and the coil arcs protrude on the front to form a convex square block 500. The first four rows of coils and the last four needles are the front coils, and the coil arcs protrude on the front to form a convex square block 500. The last four rows of coils and the last four needles are the back coils, forming a concave square block 500 (in the figure, "○" represents the back coil and "×" represents the front coil). Because all the square blocks 500 are configured in a 4:4 combination, their area is 0.64mm^2-4mm^2. Such square blocks 500 will not shrink the fabric coils too tightly due to a small area, thereby making the fabric feel hard, nor will they be scattered too much due to a large area, thereby reducing the elasticity.
[0022] The raised square blocks 500 and the recessed square blocks 500 are arranged diagonally, so when the fabric is stretched longitudinally or transversely, the recessed square blocks 500 and the raised square blocks 500 stretch the front and back sides at the same time, so that the fabric has enhanced elasticity, and the recessed square blocks 500 and the raised square blocks 500 are arranged 1:1 in the longitudinal and transverse directions. When the fabric is stretched longitudinally, the raised square blocks 500 are stretched longitudinally, but after being stretched to the length of four horizontal rows of coils, the recessed square blocks 500 on the back side are stretched longitudinally. Similarly, when the fabric is stretched transversely, the raised square blocks 500 are stretched transversely, but after being stretched to the length of 4 stitches, the recessed square blocks 500 on the back side are stretched transversely, so that the elastic stretching is evenly distributed, which not only improves the elasticity of the fabric, but also increases the stability of the elasticity of the fabric, so that the fabric will not lose its elasticity due to repeated stretching, and will not be deformed due to excessive stretching.
[0023] The fabric is formed with ventilation holes 400 by coil transfer. Figure 1In the first four rows of stitches, the stitch on the 5th needle in the second row of stitches is transferred to the 4th needle in the same row, forming a double stitch on the 4th needle in the second row of stitches, so that the 5th needle in the second row of stitches lacks a stitch. Therefore, the stitch on the 5th needle in the third row of stitches is not covered by the stitch on the 5th needle in the second row of stitches, and the two sides of the stitch column of the 5th needle in the third row of stitches are respectively pulled apart from both sides by the stitch on the 4th needle and the stitch on the 6th needle in the third row of stitches, forming an air hole 400 (the gray dotted part in the figure is the air hole 400). The same is true for the last four rows of stitches. In the sixth row of coils, the coil on the 4th needle in the sixth row of coils is transferred to the 5th needle in the same row, and a double coil is formed on the 5th needle in the sixth row of coils, so that the 5th needle in the sixth row of coils lacks a coil. Therefore, the coil on the 4th needle in the seventh row of coils is not covered by the coil on the 4th needle in the sixth row of coils, and the coil column of the 4th needle in the seventh row of coils is pulled apart from both sides by the coil on the 3rd needle and the coil on the 5th needle in the seventh row of coils, respectively, to form a ventilation hole 400, so that the fabric can maintain air circulation inside and outside when in use, thereby increasing the breathability of the fabric.
[0024] The fabric is made of 44.4dtex-77.7dtex nylon core-spun yarn woven in the weft direction with a needle count of 32 inches / 28 needles. The core yarn of the nylon core-spun yarn is spandex yarn. The tensile properties of spandex yarn can increase the elasticity of the fabric. The fabric weighs 108g / m^2 after weaving, making the fabric more elastic and able to wrap people of more body shapes. It gives users more space while making the fabric lighter and more comfortable to use.
[0025] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
