Description

Technical Field

[0001] The present invention relates to the field of fabrics, and more particularly to a mattress fabric containing phase change fibers and a preparation process thereof. Background Art

[0002] Traditional phase change material mattresses are woven using traditional weft-stitch structures. Because the weft-stitch structure has a fixed weaving pattern, when the phase change material is woven together with other fibers, due to the continuous horizontal arrangement characteristics of the weft-stitch structure, the phase change material fibers may tend to be distributed along the needle pitch direction, thereby gathering in certain areas and being less distributed in other areas, which in turn causes a delay in the temperature regulation response of the fabric layer. Summary of the Invention

[0003] The present invention aims to overcome the shortcomings of the prior art by providing a mattress fabric containing phase change fibers and a preparation process thereof. By weaving the phase change fibers into the middle layer in a floating yarn structure and evenly distributing the phase change fibers in the middle layer in the same coil rows, the phase change fibers can reduce regional clustering caused by weaving. Furthermore, when the perceived temperature is high or low, the phase change fibers absorb or release heat in the middle layer and undergo a phase change, thereby slowing the transfer of heat into the depths of the mattress. The second region within the reverse curved region forms a mesh structure, allowing air to flow freely, thereby improving the air permeability and thermal conductivity of the mattress fabric layer. The phase change fibers expand or contract during the phase change process, so the mesh structure provides a buffer, thereby increasing the phase change fiber's fracture resistance. Furthermore, because the second region is located at the trough of two adjacent, symmetrically distributed wave-shaped raised regions, the oblique distribution of the mesh structure suppresses stretchability along the length of the fabric, thereby reducing fiber breakage due to excessive stretching. The curved structure increases the surface area of ​​the mattress fabric layer, allowing the phase change fibers to sense temperature changes over a wider range, thereby improving the mattress's thermoregulatory response.

[0004] In order to achieve the above-mentioned objectives, the present invention adopts the following technical solution: a mattress fabric containing phase change fiber, which includes a front area, a middle layer and a back area from the outside to the inside, and the front area and the back area are connected by the middle layer. The front area includes a front curve area and a wave depression area symmetrically distributed on both sides of the front curve area. The back area includes a back curve area and a wave convex area symmetrically distributed on both sides of the back curve area. The back curve area includes a first area and a second area. The first area is located at the crest of two adjacent symmetrically distributed wave convex areas, and the second area is located at the trough of two adjacent symmetrically distributed wave convex areas.

[0005] The present invention is further configured such that the wave concave area is opposite to the wave convex area, and the front curved area is opposite to the back curved area.

[0006] The present invention is further configured such that, along the length direction of the fabric, the first area and the second area are alternately arranged, and along the width direction of the fabric, the first area and the wavy raised areas located on both sides of the first area are a group, and each group of the first areas is located between two adjacent second areas.

[0007] The present invention is further configured such that a plurality of meshes are distributed in the second area.

[0008] The present invention is further configured such that the height H1 of the intermediate layer between the wave recessed area and the wave raised area is smaller than the height H2 of the intermediate layer between the second area and the front curve area, and the height H2 of the intermediate layer between the second area and the front curve area is the same as the height of the intermediate layer between the first area and the front curve area.

[0014] S5: Finishing: liquid ammonia finishing.

[0015] The present invention is further configured such that the phase change fiber adopts miniemulsion polymerization technology, disperses the phase change material in the shell material monomer with a diameter of 100nm, and then polymerizes to prepare nano-microcapsules of the phase change material, and then composites the nano-microcapsules with polyester fibers.

[0016] The present invention is further configured such that, in one tissue cycle, 6 rows of coils are woven to form the wavy concave area and the wavy convex area, 16 rows of coils are woven to form the front curved area and the back curved area, and 32 rows of coils are woven to form the middle layer.

[0017] The present invention is further configured such that the 1st, 2nd, 7th, 8th, 13th, 14th, 19th, 20th, 28th, 29th, 34th, 35th, 40th, 41st, 46th, and 47th rows of stitches are knitted to form the front curved area and the back curved area, and the top needles in the 1st, 2nd, 7th, 8th, 13th, 14th, 19th, 20th, 28th, 29th, 34th, 35th, 40th, 41st, 46th, and 47th rows of stitches are knitted to form the front curved area, the bottom needles in the 1st, 2nd, 7th, 8th, 13th, 14th, 19th, 20th, 28th, 29th, 34th, 35th, 40th, 41st, 46th, and 47th rows of stitches are knitted to form the back curved area, and the bottom needles in the 25th, 26th, and 27th rows of stitches are knitted to form the back curved area. , 52, 53, 54 rows of coils are knitted to form the wavy recessed area and the wavy raised area, and the upper needles in the 25th, 26th, 27th, 52nd, 53rd, 54th rows of coils are knitted to form the wavy recessed area, the lower needles in the 25th, 26th, 27th, 52nd, 53rd, 54th rows of coils are knitted to form the wavy raised area, and the 3rd, 4th, 5th, 6th, 9th, 10th, 11th, 12th, 15th, 16th, 17th, 18th, 21st, 22nd, 23rd, 24th, 30th, 31st, 32nd, 33rd, 36th, 37th, 38th, 39th, 42nd, 43rd, 44th, 45th, 48th, 49th, 50th, 51st rows of coils are knitted to form the middle layer.

[0018] The present invention is further configured such that the 3rd, 4th, 5th, 6th, 9th, 10th, 11th, 12th, 15th, 16th, 17th, 18th, 21st, 22nd, 23rd, 24th, 30th, 31st, 32nd, 33rd, 36th, 37th, 38th, 39th, 42nd, 43rd, 44th, 45th, 48th, 49th, 50th, and 51st coil rows adopt the phase change fiber.

[0019] In summary, the present invention has the following beneficial effects:

[0020] The middle layer formed by the phase change fiber can reduce the wear and tear of the phase change fiber, and the phase change fiber is distributed in the middle layer with a floating line structure and the same coil horizontal rows, so that the phase change fiber is evenly distributed. At the same time, when the body temperature is high or low, the phase change fiber absorbs or releases heat in the middle layer of the fabric and undergoes phase change, thereby slowing down the transfer of heat to the deep part of the mattress. The second area in the reverse curved area forms a mesh structure, which increases the air permeability while providing a buffer space for the phase change fiber when the phase change occurs, thereby increasing the fracture resistance of the phase change fiber. At the same time, the oblique distribution of the mesh structure can suppress the stretchability of the curved structure in the length direction of the fabric, thereby reducing the fiber breakage caused by excessive stretching. The curved structure increases the surface area of ​​the mattress fabric layer, so that the phase change fiber can sense temperature changes in a larger range, thereby improving the temperature regulation response of the mattress.

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] This embodiment discloses a mattress fabric containing phase change fiber, the fabric includes a first yarn of polyester special-shaped cross-section fiber, a second yarn of phase change fiber, and a third yarn of combed cotton yarn, wherein the first yarn is polyester special-shaped cross-section fiber with a cross-shaped cross-section, and the phase change fiber adopts mini-emulsion polymerization technology, by dispersing phase change material in shell material monomer with a diameter of 100nm, and then polymerizing to prepare nano-microcapsules of phase change material, and then compounding the nano-microcapsules with polyester fiber. The fabric is arranged in 54 coils horizontally. In a weaving cycle, the needle selection in each row of coils is that the upper needle plate needles are in 2 sections and the lower needle cylinder needles are in 4 sections. The upper needle plate needles are arranged in the order of 1212..., and the lower needle cylinder needles are arranged in the order of (12)*6(34)*6. In a weaving cycle, each row of coils in the 1st, 2nd, 7th, 8th, 13th, 14th, 19th, 20th, 25th, 26th, 27th, 28th, 29th, 34th, 35th, 40th, 41st, 46th, 47th, 52nd, 53rd, and 54th rows is knitted with two yarns. , each of the 3rd, 4th, 5th, 6th, 9th, 10th, 11th, 12th, 15th, 16th, 17th, 18th, 21st, 22nd, 23rd, 24th, 30th, 31st, 32nd, 33rd, 36th, 37th, 38th, 39th, 42nd, 43rd, 44th, 45th, 48th, 49th, 50th, 51st rows of stitches are knitted with one yarn, and the 1st, 2nd, 7th, 8th, 13th, 14th, 19th, 20th, 25th, 26th, 27th, 28th, 29th, 34th, 35th, 40th, 41st, 46th, 47th The upper needle disc of each of the 52nd, 53rd and 54th coil rows is made of polyester cross-section fiber, and the lower needle cylinder is made of combed cotton yarn, while the 3rd, 4th, 5th, 6th, 9th, 10th, 11th, 12th, 15th, 16th, 17th, 18th, 21st, 22nd, 23rd, 24th, 30th, 31st, 32nd, 33rd, 36th, 37th, 38th, 39th, 42nd, 43rd, 44th, 45th, 48th, 49th, 50th and 51st coil rows are made of phase change fiber, and the fabric is finished with liquid ammonia after leaving the machine.

[0031] In one weaving cycle, the 1st, 2nd, 7th, 8th, 13th, 14th, 19th, 20th, 25th, 26th, 27th, 28th, 29th, 34th, 35th, 40th, 41st, 46th, 47th, 52nd, 53rd, and 54th rows of stitches are all knitted on the 2-stage needles of the upper needle dial and the 4-stage needles of the lower needle cylinder. In this embodiment, the upper needle dial knits to form the front side of the fabric, and the lower needle cylinder knits to form the back side of the fabric, while the 3rd, 4th, 5th, 6th, 9th, 10th, 11th, 12th, 15th, 16th, 17th, 18th, 21st, 22nd, 23rd, 24th, 30th, 31st, 32nd, 33rd, 36th, 37th, 38th, 39th, 42nd, 43rd, 44th, 45th, 48th, 49th, 50th, and 51st rows of stitches are all knitted on the 3rd, 5th, 9th, 11th, 15th , 17, 21, 23, 30, 32, 36, 38, 42, 44, 48, 50 courses are knitted only on the lower needle cylinder, and the 4th, 6th, 10th, 12th, 16th, 18, 22, 24, 31st, 33rd, 37th, 39th, 43rd, 45th, 49th, 51st courses are knitted only on the upper needle dial. Therefore, in this embodiment, the two sections of knitting needles of the upper needle dial of the 1st, 2nd, 7th, 8th courses knit to form the front area 100 of the fabric, and the four sections of knitting needles of the lower needle cylinder of the 1st, 2nd, 7th, 8th courses knit to form the back area 200 of the fabric. At the same time, because the 3rd, 4th, 5th, 6th courses are knitted only on the upper needle dial or the lower needle cylinder, the 1st, 2nd, 7th, 8th courses on both sides of the 3rd, 4th, 5th, 6th courses are knitted only on the upper needle dial or the lower needle cylinder. Because of the internal stress of the loops formed by the knitting of the upper needle plate and the lower needle cylinder in the 7th and 8th courses, the yarns of the 3rd, 4th, 5th and 6th courses are hidden under the loops of the 1st, 2nd, 7th and 8th courses. At the same time, because the knitting of the lower needle cylinder of the 3rd and 5th courses is not connected with the knitting of the upper needle plate of the 4th and 6th courses, the 3rd, 4th, 5th and 6th courses are connected to the 1st, 2nd, 7th and 8th courses by the floating thread of the changing plain stitch. Therefore, the 3rd, 4th, 5th and 6th courses are knitted to form an intermediate layer 300, and the front area 100 and the back area 200 are connected through the intermediate layer 300. Similarly, the front area 100 and the back area 200 formed by the knitting of the 7th, 8th, 13th and 14th courses are connected through the 9th, 10th, 11th and 14th courses. The front area 100 and the back area 200 formed by the 12th course of stitches are connected through the middle layer 300 knitted by the 13th, 14th, 19th and 20th courses, respectively. The front area 100 and the back area 200 formed by the 15th, 16th, 17th and 18th courses are connected through the middle layer 300 knitted by the 19th, 20th, 25th, 26th, 27th, 28th and 29th courses are connected through the middle layer 300 knitted by the 21st, 22nd, 23rd and 24th courses. The front area 100 and the back area 200 formed by the 25th, 26th, 27th, 28th, 29th, 34th and 35th courses are connected through the middle layer 300 knitted by the 30th, 31st, 32nd and 33rd courses.The front area 100 formed by knitting the 34th, 35th, 40th and 41st coil courses is connected to the back area 200 through the middle layer 300 knitted by the 36th, 37th, 38th and 39th coil courses. The front area 100 formed by knitting the 40th, 41st, 46th and 47th coil courses is connected to the back area 200 through the middle layer 300 knitted by the 42nd, 43rd, 44th and 45th coil courses. The front area 100 formed by knitting the 46th, 47th, 52nd, 53rd, 54th and 55th coil courses is connected to the back area 200 through the middle layer 300 knitted by the 41st, 46th and 47th coil courses. The back area 200 is connected to the middle layer 300 formed by knitting the 48th, 49th, 50th and 51st stitches in the course. Therefore, the 3rd, 4th, 5th, 6th, 9th, 10th, 11th, 12th, 15th, 16th, 17th, 18th, 21st, 22nd, 23rd, 24th, 30th, 31st, 32nd, 33rd, 36th, 37th, 38th, 39th, 42nd, 43rd, 44th, 45th, 48th, 49th, 50th and 51st stitches in the course are knitted to form the middle layer 300. In one weave cycle, 32 stitches in the course are knitted to form the middle layer. 300, and the fabric includes the front area 100, the middle layer 300 and the back area 200 from the outside to the inside, and the front area 100 and the back area 200 are connected through the middle layer 300, so that the phase change fiber of the middle layer 300 not only connects the front area 100 and the back area 200 with a floating line structure, but also is distributed in 4-way coil rows between the front area 100 and the back area 200, so that the phase change fiber can be evenly distributed between the front area 100 and the back area 200, reducing the occurrence of local coils during the weaving process. At the same time, when the perceived temperature is high or low, the phase change fibers can absorb or release heat and undergo phase change, thereby slowing the transfer of heat to the mattress, thereby protecting the comfort layer and reducing the problem of material aging caused by excessive temperature differences. At the same time, the phase change fibers are located in the middle layer 300 and hidden under the coils of the front area 100 and the back area 200. The phase change fibers have a floating wire structure, so the phase change fibers will not be excessively squeezed or constrained during phase change, thereby preventing the phase change fibers from breaking or damaging.

[0032] In the 1st, 2nd, 7th, 8th, 13th, 14th, 19th, 20th, 25th, 26th, 27th, 28th, 29th, 34th, 35th, 40th, 41st, 46th, 47th, 52nd, 53rd, and 54th rows of stitches in the front area 100 and the back area 200, the 4-segment knitting needles in the lower needle cylinder in the 1st, 2nd, 7th, 8th, 13th, 14th, 19th, 20th, 28th, 29th, 34th, 35th, 40th, 41st, 46th, and 47th rows of stitches are knitted with 1-segment tuck and 3-segment loops, and the 2-segment knitting needles in the upper needle disk in the 1st, 2nd, 7th, 8th, 13th, 14th, 19th, 20th, 28th, 29th, 34th, 35th, 40th, 41st, 46th, and 47th rows of stitches are knitted with 1-segment float and 1 Therefore, during the knitting process, by changing the shifting mechanism of the needle bed, the knitting needles of the upper needle disc and the lower needle cylinder cooperate with each other, so that the 1st, 2nd, 7th, 8th, 13th, 14th, 19th, 20th, 28th, 29th, 34th, 35th, 40th, 41st, 46th, and 47th rows of stitches are knitted to form the front curve area 102 and the back curve area 202, and the upper needles in the 1st, 2nd, 7th, 8th, 13th, 14th, 19th, 20th, 28th, 29th, 34th, 35th, 40th, 41st, 46th, and 47th rows of stitches are knitted to form the front curve area 102, and the upper needles in the 1st, 2nd, 7th, 8th, 13th, 14th, 19th, 20th, 28th, 29th, 34th, 35th, 40th, The lower needles in the course knit to form the reverse curved area 202, while the four sections of knitting needles of the lower needle cylinder in the 25th, 26th, 27th, 52nd, 53rd, and 54th courses are knitted with two sections of loops and two sections of floating yarn, and the two sections of knitting needles of the upper needle dial in the 25th, 26th, 27th, 52nd, 53rd, and 54th courses are knitted with one section of loops and one section of floating yarn. Therefore, the loops and floating yarns of the lower needle cylinder and the upper needle dial in the 25th, 26th, 27th, 52nd, 53rd, and 54th courses differ by two times. Therefore, in the knitting process, by using the same method as in the 1st, 2nd, 7th, 8th, 13th, 14th, 19th, 20th, 28th, 29th, 34th, 35th, 40th, 41st, 46th, and 47th courses, The shift mechanism of the needle bed is changed so that the knitting needles of the upper needle disc and the lower needle cylinder cooperate with each other, so that the 25th, 26th, 27th, 52nd, 53rd and 54th coil rows are knitted to form the wave concave area 101 and the wave convex area 201, and the upper needles in the 25th, 26th, 27th, 52nd, 53rd and 54th coil rows are knitted to form the wave concave area 101, and the lower needles in the 25th, 26th, 27th, 52nd, 53rd and 54th coil rows are knitted to form the wave convex area 201, and the 25th, 26th and 27th coil rows are located between the 1st, 2nd, 7th, 8th, 13th, 14th, 19th and 20th coil rows and the 28th, 29th, 34th, 35th, 40th, 41st, 46th and 47th coil rows.The 52nd, 53rd and 54th rows of stitches are located between the 28th, 29th, 34th, 35th, 40th, 41st, 46th and 47th rows of stitches and the 1st, 2nd, 7th, 8th, 13th, 14th, 19th and 20th rows of stitches in the next cycle. Therefore, the front area 100 includes the front curve area 102 and the wave recessed areas 101 symmetrically distributed on both sides of the front curve area 102. The back area 200 includes the back curve area 202 and the wave raised areas 201 symmetrically distributed on both sides of the back curve area 202. Therefore, in one weaving cycle, 6 rows of stitches are knitted to form the wave recessed areas 101 and the wave raised areas 201, and 16 rows of stitches are knitted to form the front curve area 102 and the back curve area 202. Because the front area 100 and the back area 200 are located in the same row of stitches, when the fabric is knitted, the wave recessed areas 101 and the wave raised areas 201 are symmetrically distributed on both sides of the back curve area 202. 1, the front curved area 102 and the back curved area 202 are opposite each other. Because the wavy concave area 101 and the front curved area 102 use polyester cross-section fibers, and the fabric is finished with liquid ammonia, the polyester special-shaped cross-section fibers increase the fabric's breathability. Combined with the heat absorption and melting of the phase change fibers in the middle layer 300, the surface temperature of the fabric is synergistically reduced. At the same time, the liquid ammonia finishing increases the surface softness. The wavy raised area 201 and the back curved area 202 use combed cotton yarn, which, in combination with the wavy concave area 101 and the front curved area 102, increases the overall breathability of the fabric. The curved structure of the front curved area 102 and the back curved area 202, combined with the wavy structure of the wavy concave area 101 and the wavy raised area 201, increases the surface area of ​​the fabric mattress layer, allowing the phase change fibers in the middle layer 300 to sense temperature changes over a wider range, thereby improving the mattress's temperature regulation response.

[0033] In the lower needle cylinders of the 1st, 2nd, 7th, 8th, 13th, 14th, 19th, 20th, 28th, 29th, 34th, 35th, 40th, 41st, 46th and 47th courses for knitting the reverse curved area 202, the lower needle cylinders of the 1st, 2nd, 13th and 14th courses knit tuck stitches on the 1st needle, and the 2nd, 3rd and 4th needles are floated, the lower needle cylinders of the 7th, 8th, 19th and 20th courses knit tuck stitches on the 2nd needle, and the 1st, 3rd and 4th needles are floated, and the lower needle cylinders of the 28th, 29th, 40th and 41st courses knit tuck stitches on the 3rd needle, and the 1st, 2nd and 4th needles are floated, and the lower needle cylinders of the 34th, 35th, 46th and 47th courses knit tuck stitches on the 4th needle, and the 1st, 2nd and 3rd needles are floated. The first and second needles of the lower needle cylinder in the 7th, 8th, 13th, 14th, 19th, 20th, 28th, 29th, 34th, 35th, 40th, 41st, 46th, and 47th courses are grouped together, and the third and fourth needles are grouped together. The first and second needles of the lower needle cylinder in the 1st, 2nd, 7th, 8th, 13th, 14th, 19th, and 20th courses are knitted to form the second region 2022, and the third and fourth needles are knitted to form the first region 2021. The third and fourth needles of the lower needle cylinder in the 28th, 29th, 34th, 35th, 40th, 41st, 46th, and 47th courses are knitted to form the second region 2022, and the first and second needles are knitted to form the first region 2021. Therefore, the reverse curved area 202 includes the first region 2021 and the second region 2022. Therefore, the first region During the knitting process, the first area 2021 and the second area 2022 are positioned at the crest of two adjacent symmetrically distributed wave raised areas 201, and the second area 2022 is positioned at the trough of two adjacent symmetrically distributed wave raised areas 201, through the cooperation of the needle bed shifting mechanism. Because the first area 2021 and the second area 2022 are positioned in the same row of stitches but on different knitting needles, the first area 2021 and the second area 2022 are arranged alternately along the length direction of the fabric. When the first area 2021 is positioned at the 3rd and 4th needles of the 1st, 2nd, 7th, 8th, 13th, 14th, 19th and 20th rows of stitches, it is grouped together with the 3rd and 4th needles of the 25th, 26th and 27th rows of stitches, and the 28th, 29th and 30th rows of stitches are grouped together with the 3rd and 4th needles of the 28th, 29th and 31st rows of stitches. The 3rd and 4th bottom stitches of the 4th, 35th, 40th, 41st, 46th and 47th rows are the second area 2022. Therefore, in the weave cycle, along the width direction of the fabric, the first area 2021 and the wave raised areas 201 on both sides of the first area 2021 are a group, and each group of first areas 2021 is located between two adjacent second areas 2022. Because the coils are woven transversely, the fabric itself has a certain elasticity along the width direction. The curved structure of the wave recessed area 101, the wave raised area 201, the front curved area 102 and the back curved area 202 makes the fabric have a certain tensile resistance in the length direction, so that the phase change fiber of the middle layer 300 will not be easily displaced when the phase change occurs, thereby keeping the phase change fiber uniform.This will prevent the fabric from experiencing a temperature adjustment response lag.

[0034] Because the second area 2022 is located at the 1st and 2nd bottom stitches of the 1st, 2nd, 7th, 8th, 13th, 14th, 19th and 20th stitch rows and the 3rd and 4th bottom stitches of the 28th, 29th, 34th, 35th, 40th, 41st, 46th and 47th stitch rows, and there is a tuck stitch in the 1st and 2nd bottom stitches of the 1st, 2nd, 7th, 8th, 13th, 14th, 19th and 20th stitch rows, and there is also a tuck stitch in the 3rd and 4th bottom stitches of the 28th, 29th, 34th, 35th, 40th, 41st, 46th and 47th stitch rows, and the tuck stitch transfers the stitches to form mesh holes 2023 there, so there are multiple mesh holes 2023 distributed in the second area 2022, and because the second area 2022 is formed by tuck stitches and formed stitches, there is no float stitch, and the first area 2021 is all formed stitches. There is no floating line, and the wave raised area 201 is formed by loops and floating lines, so the loops of the second area 2022 and the first area 2021 squeeze the floating lines of the wave raised area 201 and bulge, so that the wave raised area 201 is higher than the second area 2022 and the first area 2021, and the front curve area 102 and the wave recessed area 101 are both loops and floating lines, but because the front curve area 102 is a 2-way coil row, and the wave recessed area 101 is a 3-way coil row, there are 8 front curve areas 102 between the wave recessed areas 101. Therefore, during the knitting process, due to the internal stress of the yarn, the wave recessed area 101 is lower than the front curve area 102, and because the front curve area 102 is opposite to the back curve area 202, the wave recessed area 101 is 01 is opposite to the wave raised area 201, so the height H1 of the middle layer 300 between the wave recessed area 101 and the wave raised area 201 is less than the height H2 of the middle layer 300 between the second area 2022 and the front curve area 102, and the height H2 of the middle layer 300 between the second area 2022 and the front curve area 102 is the same as the height of the middle layer 300 between the first area 2021 and the front curve area 102, so that the phase change fiber can form a gradient distribution in the middle layer 300, so the second area 2022 forms a mesh structure to allow air to flow freely, and the middle layer 300 of the front area 100 and the back area 200 are connected and change in a gradient, so that the air is allowed to flow in the fabric through the mesh 2023 of the second area 2022. The second region 2022 is a mesh structure, and the second region 2022 is obliquely distributed, so that when the phase change fiber changes volume during the phase change process, a buffer space for fiber change can be formed, thereby increasing the anti-fracture performance of the phase change fiber and improving the temperature regulation response of the mattress. The mesh structure of the second region 2022 is formed by tucking, and the tucking is to transfer the coil to form a mesh 2023 at this location, and to form multiple overlapping coils at another location.Therefore, while the curved structure increases the stretchability of the fabric in the longitudinal direction, the mesh structure will suppress some of the stretching due to the overlapping of multiple coils, thus preventing the fiber from breaking due to excessive stretching.
