Description

Technical Field

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

[0002] Currently, mattresses use soft fabric layers. However, because the fabric layer has a flat structure, it comes into direct contact with the filling layer, resulting in a large contact area. This causes friction between the fabric layer and the filling layer. Furthermore, when a person falls asleep, the flat structure of the fabric layer causes pressure to concentrate, thus reducing the lifespan of the mattress. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a flexible mattress fabric. The fabric is formed by weaving fibers into diamond-shaped units, and each diamond-shaped unit has a fan-shaped recess inside. Because the fan-shaped recess has an arc and a certain depth, the first area inside the diamond-shaped unit, which also has an arc, is raised. The fan-shaped recess forms multiple buffer zones on the surface of the fabric, thereby reducing the wear of the filling layer. Furthermore, the specific oblique arrangement of the arc and the concave-convex structure allows the fabric layer to distribute external stress over a larger area, reducing pressure points and thus increasing the lifespan of the mattress.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a flexible mattress fabric, comprising rhomboid units, each of the rhomboid units being arranged obliquely at a 45-degree angle, each of the rhomboid units comprising a first region and a second region, the second region being fan-shaped, and the center of the second region being located at one corner of the rhomboid unit, and the first region being higher than the second region.

[0005] The present invention is further configured such that each of the second regions is a quarter circle, and the center of each of the second regions is located at the lower corner of the rhombus unit.

[0006] The present invention is further configured such that the radius L2 of each second region is half the side length L1 of the rhombic unit.

[0007] The present invention is further configured such that the height difference H between the first region and the second region is 0.36mm-0.72mm.

[0008] The present invention is further configured such that the fabric is woven in a 24-way loop as one cycle, a 16-way loop as one cycle to form the first region, and an 8-way loop as one cycle to form the second region.

[0009] The present invention is further configured such that the first region is formed by weaving together the first to eighth coil rows and the 13th to 20th coil rows, and the second region is formed by weaving together the 9th to 12th coil rows and the 21st to 24th coil rows.

[0010] The present invention is further configured such that the coil density of the first region is 18 pins / inch and the coil density of the second region is 15 pins / inch.

[0011] The present invention is further configured such that all 24 rows of coils in the fabric are made of 70D / 144F polyester elastic yarn.

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

[0013] The fabric is woven with fibers to form diamond-shaped units, and each diamond-shaped unit has a fan-shaped depression and a first area inside. The first area is higher than the fan-shaped depression, thus creating a certain curvature and uneven structure on the fabric surface. The fan-shaped depression increases the cushioning of the filling layer, thereby reducing wear on the filling layer. At the same time, the specific diagonal arrangement allows the fabric layer to disperse external stress, increasing the feel of the fabric layer while reducing local pressure concentration, thereby increasing the lifespan of the mattress.

[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 flexible mattress fabric, including a diamond-shaped unit 30. The fabric is woven in a 24-row stitch pattern, forming a loop. In one weave loop, 16 rows of stitches form a first region 301 within the loop, and 8 rows of stitches form a second region 302 within the loop. Each row of stitches in the 24-row stitch pattern includes one row of purl stitches and two rows of knit stitches. Rows 1-8 are woven into a loop at the first knit stitch, with no purl stitches. Rows 13-20 are woven into a loop at the second knit stitch, with no purl stitches. Therefore, rows 1-8 and rows 13-20 form the first region 301, while rows 9-12... All rows of loops are knitted into loops at the first knit stitch and all purl stitches are knitted into loops. The 21st to 24th loop rows are knitted into loops at the second knit stitch and all purl stitches are knitted into loops. Therefore, the 9th to 12th loop rows and the 21st to 24th loop rows are knitted to form the second region 302. Thus, each diamond unit 30 includes the first region 301 and the second region 302. Furthermore, each diamond unit 30 is knitted in a 45-degree angled arrangement. This allows the fabric to adapt to deformation under stress in the length direction, width direction, and diagonal direction. It can also quickly rebound when the external stress disappears, keeping the fabric surface in its original state. When a person lies on it, the fabric layer can distribute the external stress over a larger area, thereby reducing pressure concentration.

[0022] Because the 9th, 10th, 11th, and 12th loop rows and the 21st, 22nd, 23rd, and 24th loop rows are woven into loops on both the purl and knitting needles, but the number of loops on the purl needles is twice the number of loops on the knitting needles, the second region 302 becomes fan-shaped due to the traction between the fibers after the fabric is woven. Furthermore, because the number of loops on the purl needles is large, the traction between the fibers in the purl direction of the second region 302 is greater than the traction between the fibers in the knitting needle direction. Therefore, the first region 301 is higher than the second region 302, and the height difference H between the first region 301 and the second region 302 is 0.36mm-0.72mm, preferably 0.6mm. This results in the second region 302 forming a fan-shaped depression. The first region 301 is formed by weaving the 1st to 8th loops and the 13th to 20th loops. The number of loops formed by the down stitches in the first region 301 is half the number of loops formed by the up stitches in the second region 302. Therefore, due to the traction between the up stitches in the second region 302, the first region 301 is always higher than the second region 302. Thus, when the mattress fabric layer is wrapped, the uneven structure of the fabric layer reduces the contact area between the fabric layer and the filling layer, thereby reducing the wear of the filling layer. Furthermore, because the second region 302 is fan-shaped and has a certain curvature, the first region 301 also has a certain curvature, thus the second region 302 forms a buffer zone. When the fabric layer is subjected to external stress, it can disperse the external stress, thereby reducing the deformation or damage of the mattress fabric layer and extending the service life of the mattress.

[0023] Because the knitting positions of the 9th to 12th loops of the second region 302 are the same as those of the 1st to 8th loops of the first region 301, and the knitting positions of the 21st to 24th loops of the second region 302 are the same as those of the 13th to 20th loops of the first region 301, each second region 302 is a quarter circle. The center of each second region 302 is located at one corner of the rhombus unit 30, and the center of each second region 302 is located at the lower corner of the rhombus unit 30. The number of loops formed by the upper needle in each second region 302 is twice the number of loops formed by the lower needle, and also twice the number of loops formed by the lower needle in the first region 301. Therefore, the radius L2 of each second region 302 is half the side length L1 of the rhombus unit 30. Thus, through the fan-shaped indentation of the second region 302, the stress can be dispersed along the arc path when the fabric is subjected to external stress, thereby avoiding deformation caused by stress concentration. At the same time, the curvature of the edges of the first region 301 and the second region 302 increases the degree of freedom of fabric layer deformation, thereby adapting to the deformation of the fabric when subjected to external stress.

[0024] Because the 16-way coil row of the first area 301 uses a coil density of 18 stitches / inch, and the 8-way coil row of the second area 302 uses a coil density of 15 stitches / inch, the coil rows of the diamond unit 30 decrease in angle from the three corners downwards. Furthermore, all 24-way coil rows of the fabric use 70D / 144F polyester elastic yarn, thus creating an elastic gradient in the fabric. This allows for increased structural deformation of the diamond unit 30 in multiple directions, while also expanding the direction of elastic action, giving the fabric a good hand feel when subjected to external stress.

All technical solutions falling within the scope of this utility model's concept are protected.
