Description

Technical Field

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

[0002] Existing mattresses often use a tightly woven structure to increase the strength of the mattress fabric layer. However, because the tight weave structure makes the gaps between the fibers smaller, the air circulation inside the fabric is poor. As a result, the mattress fabric layer cannot meet the body's heat dissipation needs, leading to increased moisture accumulation during sleep, which further affects the strength and durability of the mattress fabric layer. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a high-strength breathable fabric. This fabric is constructed using yarn weaving to form a three-layer structure: an outer layer, an air interlayer, and an inner layer. The obliquely raised outer layer reduces localized pressure concentration and guides airflow through the design of the oblique raised areas and grooves, thereby increasing breathability. The air interlayer, woven with yarn, cushions the fabric under external force while increasing its support, thus increasing its strength. Furthermore, the ventilation holes within the grooves enhance internal airflow, and the gaps between the fibers in the air interlayer reduce moisture accumulation, thereby increasing the fabric's structural stability.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a high-strength breathable fabric, comprising a surface layer, an air interlayer, and an inner layer, wherein the air interlayer is formed between the surface layer and the inner layer, the surface layer includes obliquely raised areas and grooves, the grooves being located between two obliquely raised areas and the obliquely raised areas being higher than the grooves, the fabric having breathable holes that penetrate the grooves, the air interlayer, and the inner layer.

[0005] The present invention is further configured such that the oblique protrusion area and the groove are arranged obliquely, and the inclination angle α between the oblique protrusion area and the groove is 30 degrees to 60 degrees.

[0006] The present invention is further configured such that the width ratio of the oblique protrusion area to the width of the groove is 1:1 to 3:1.

[0007] The present invention is further configured such that the height difference H between the oblique protrusion area and the groove is 2mm-5mm.

[0008] The present invention is further configured such that the distance between two obliquely adjacent vent holes is equal to the diameter of one vent hole.

[0009] The present invention is further configured such that the fabric is woven in a 24-way loop pattern, the outer layer is formed by knitting the down stitches in the 24-way loop pattern, the inner layer is formed by knitting the up stitches in the 24-way loop pattern, and the air interlayer is formed by knitting the 1st, 2nd, 4th, 5th, 7th, 8th, 10th, 11th, 13th, 14th, 16th, 17th, 19th, 20th, 22nd, and 23rd loop patterns.

[0010] The present invention is further configured such that, in the 16 coil rows of the air interlayer, the density of the coil rows 1, 4, 7, 10, 13, 16, 19, and 22 is 12 coils / cm, and the density of the coil rows 2, 5, 8, 11, 14, 17, 20, and 23 is 8 coils / cm.

[0011] The present invention is further configured such that the surface layer is woven from polyester and spandex fibers, and the air interlayer is made of polyester monofilament.

[0012] In summary, this utility model has the following beneficial effects:

[0013] The fabric is constructed using a three-layer structure consisting of an outer layer, an air-insertion layer, and an inner layer. The diagonal protrusions formed by the yarn weaving disperse external forces, while grooves are created between these protrusions, with ventilation holes located within these grooves and penetrating the fabric. This ventilation holes increase airflow within the fabric, and the protrusions and grooves guide this airflow, allowing for air exchange within the fabric. This increases the fabric's breathability while maintaining its internal structural stability. Furthermore, the air-insertion layer weaves a buffer against external forces on the outer layer and supports the outer layer, thus increasing the overall strength of the fabric.

[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 5 As shown, this embodiment discloses a high-strength breathable fabric, including an outer layer 100, an air interlayer 200, and an inner layer 300. The fabric has a weave cycle of 24 stitches per row. In each of the 24 stitch rows, there are 2 knitting needles in the purl row and 4 knitting needles in the purl row. The knitting sequence of the 2 knitting needles in each row is that the 2nd needle knits first, then the 1st needle knits. The knitting sequence of the 4 knitting needles in each row is that the 1st needle knits first, then the 2nd needle knits twice, then the 2nd needle knits twice, then the 4th needle knits twice, then the 3rd needle knits twice. After the third needle repeats the cycle twice, the first needle begins knitting. In the 24-row loop, the outer layer 100 is formed by knitting the knit stitches in the 24-row loop, the inner layer 300 is formed by knitting the purl stitches in the 24-row loop, and the air gap 200 is formed by knitting the 1st, 2nd, 4th, 5th, 7th, 8th, 10th, 11th, 13th, 14th, 16th, 17th, 19th, 20th, 22nd, and 23rd rows of loops. Therefore, an air gap 200 is formed between the outer layer 100 and the inner layer 300. This multi-layer structure is formed through fiber knitting, allowing the fibers of the three layers to interweave and support each other, thereby replacing the tightness of the fabric knitting. This maintains the strength of the fabric while increasing the gaps between the fibers, thus increasing the breathability of the fabric.

[0022] Because the air interlayer 200 is formed by weaving together the 1st, 2nd, 4th, 5th, 7th, 8th, 10th, 11th, 13th, 14th, 16th, 17th, 19th, 20th, 22nd, and 23rd coil rows, and in the 16 coil rows of the air interlayer 200, refer to... Figure 5In the first four rows (1, 4, 7, 10, 13, 16, 19, and 22), all loops are knitted with knit stitches, and the ratio of knitted stitches to float stitches is 8:2. In the second four rows (2, 5, 8, 11, 14, 17, 20, and 23), all loops are knitted with purl stitches, and the ratio of knitted stitches to float stitches is 1:1. Therefore, the density of loops 1, 4, 7, 10, 13, 16, 19, and 22 is 12 stitches / cm, and the density of loops 2, 5, 8, 11, 14, 17, 20, and 23 is 8 stitches / cm. Knitted loops represent the outer layer 100 of the fabric, and purlted loops represent the inner layer 300. Therefore, the density of the connection between the air gap 200 and the outer layer 100 gradually decreases towards the density of the connection between the air gap 200 and the inner layer 300, thus improving the airflow within the fabric. As the permeability gradually increases, the use of polyester monofilament in the air layer 200 gradually increases the internal air circulation space of the fabric, thereby increasing the fabric's breathability. Furthermore, the use of polyester monofilament provides sufficient support for the air layer 200, increasing the fabric's durability. The high density at the connection between the air layer 200 and the outer layer 100 increases the support of the air layer 200 for the outer layer 100 under external force, reducing localized pressure on the outer layer 100 and maintaining the fabric's strength and structural stability. Simultaneously, the low density at the connection between the air layer 200 and the inner layer 300 reduces the impact force on the outer layer 100 under external force. The raised design reduces the contact area between the fabric and the skin, thereby reducing friction between the fibers of the air layer 200 and the inner layer 300, reducing fabric wear, and increasing fabric strength.

[0023] Because the knitting of the 24-row loops forms the surface layer 100, and in the 1st, 3rd, 4th, 6th, 7th, 9th, 10th, 12th, 13th, 15th, 16th, 18th, 19th, 21st, 22nd, and 24th loops, the ratio of the number of knitting stitches in the 1st, 4th, 7th, 10th, 13th, 16th, 19th, and 22nd loops to the number of knitting stitches in the 3rd, 6th, 9th, 12th, 15th, 18th, 21st, and 24th loops is 6:4, the surface layer 100 is knitted to form an oblique raised area 111 and a groove 112. This is because the 3rd loop is located between the 1st and 4th loops, the 6th loop is located between the 4th and 7th loops, the 9th loop is located between the 7th and 10th loops, the 12th loop is located between the 10th and 13th loops, and the 15th loop... The horizontal row is located between the 13th and 16th coil rows, the 18th coil row is located between the 16th and 19th coil rows, the 21st coil row is located between the 19th and 22nd coil rows, and the 24th coil row is located between the 22nd and 1st coil rows. Therefore, the groove 112 is located between the two obliquely raised areas 111. Because of the number of stitches in the loop, the obliquely raised areas 111 are higher than the groove 112. The height difference H between the obliquely raised areas 111 and the groove 112 is 2mm-5mm. Preferably, the height difference H between the obliquely raised areas 111 and the groove 112 is 3mm. Therefore, when subjected to an external force perpendicular to the fabric surface, the concave-convex structure design between the obliquely raised areas 111 and the groove 112 can increase a certain buffer, so that the fabric surface will not deform and produce a bulge.

[0024] Because the ratio of the number of knitting needles in the 1st, 4th, 7th, 10th, 13th, 16th, 19th, and 22nd loop rows to the number of knitting needles in the 3rd, 6th, 9th, 12th, 15th, 18th, 21st, and 24th loop rows is 6:4, and the 1st, 4th, 7th, 10th, 13th, 16th, 19th, and 22nd loop rows form a diagonally raised area 111, while the 3rd, 6th, 9th, 12th, 15th, 18th, 21st, and 24th loop rows form a groove 112, the ratio of the width of the diagonally raised area 111 to the width of the groove 112 is 1:1 to 3:1. Preferably, the ratio is 2:1, and the diagonally raised area 111 and the groove 112 are arranged diagonally. The inclination angle α between the oblique raised area 111 and the groove 112 is 30 degrees to 60 degrees. Preferably, the inclination angle α between the oblique raised area 111 and the groove 112 is 45 degrees. Since the surface layer 100 is woven with polyester and spandex fibers, the fabric surface can effectively disperse external forces, thereby avoiding the fabric strength reduction due to excessive local stress. At the same time, due to the presence of spandex fibers, the oblique raised area 111 has good resilience, thereby forming good air circulation between the three layers of the fabric. Furthermore, since the density of the oblique raised area 111 is higher than that of the groove 112, the oblique raised area 111 can guide air to circulate on the fabric surface, while the groove 112 can guide air to circulate inside the fabric, thereby increasing the breathability of the fabric.

[0025] Reference Figure 5Because in the 3rd, 6th, 9th, 12th, 15th, 18th, 21st, and 24th loop rows, the knit and purl stitches in the 3rd, 15th, 18th, and 21st loop rows form a "W" shape, while the knit and purl stitches in the 6th, 9th, 12th, and 24th loop rows form a "U" shape, the fabric has ventilation holes 1121. These ventilation holes 1121 penetrate the groove 112, the air interlayer 200, and the inner layer 300. Furthermore, two obliquely adjacent ventilation holes 1121 are spaced apart by the aperture distance of one ventilation hole 1121, thus promoting air circulation in the fabric. Because the ventilation holes penetrate the fabric, air inside the fabric can exchange with the outside, thereby reducing the internal air pressure and increasing the fabric's strength and structural stability. And because the ventilation holes 1121 penetrate the fabric, the obliquely convex... Because of its protrusion, the raised area 111 forms a cavity between the obliquely raised area 111 and the air gap 200. Therefore, when the fabric surface is subjected to external force from the human body, the external force is not only dispersed by the obliquely raised area 111, but the heat generated by the human body can also be squeezed through the obliquely raised area 111. As the air gap 200 gradually decreases in density, the air gap 200 and the vent 1121 form a through-flow and exchange space for air within the fabric. Thus, the heat generated by the human body is discharged into the air gap 200 and flows through the air gap 200 to the vent 1121, where air is exchanged and circulated. Therefore, it not only promotes vertical airflow within the fabric, but also creates multi-directional air permeability within the fabric, thereby increasing the breathability of the fabric while stabilizing its strength.

All technical solutions falling within the scope of this utility model's concept are protected by this utility model. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
