Description

Technical Field

[0001] The utility model belongs to the technical field of mattresses and relates to an anti-deformation 3D material and a mattress. Background Art

[0002] As an advanced textile structural material, 3D materials offer broad application prospects across multiple fields due to their unique three-dimensional structure and excellent breathability. However, traditional 3D materials are prone to deformation when subjected to external forces, limiting their use in certain applications requiring high stability. For example, some mattresses using 3D materials can cause the mattress to sag during handling due to their excessive softness. For example, lifting the ends of the mattress causes the center to sag first, increasing the difficulty of handling. Summary of the Invention

[0003] In view of the problems existing in the prior art, the present invention proposes an anti-deformation 3D material and a mattress, aiming to overcome the defect that the existing 3D material mattresses are prone to significant deformation.

[0004] The utility model is achieved in this way:

[0005] A deformation-resistant 3D material includes an upper mesh cloth, a lower mesh cloth, and a support wire connected between the upper mesh cloth and the lower mesh cloth. At least one layer of the upper mesh cloth and the lower mesh cloth is woven from a composite braided wire, and the composite braided wire includes yarn and hot-melt yarn attached to the yarn.

[0006] The addition of hot-melt yarn to the composite braid significantly enhances the material's structural stability. The hot-melt yarn melts at high temperatures and bonds to the yarn, creating a tighter and stronger braid that effectively resists deformation. The addition of hot-melt yarn not only enhances the material's structural strength but also improves its durability.

[0007] Preferably, the yarn and the hot-melt yarn are intertwined and twisted together. This physical interweaving not only increases the overall strength of the material but also strengthens the bond between the yarn and the hot-melt yarn. This tightly bound structure effectively resists deformation when subjected to external forces, maintaining the material's shape.

[0008] Preferably, the support filaments are C-shaped. C-shaped support filaments provide better support. When the 3D material is subjected to pressure, the C-shaped support filaments can more effectively disperse the pressure, reducing single-point pressure and thus enhancing the support force of the 3D material. The numerous tiny gaps formed between the C-shaped support filaments facilitate air circulation and improve the breathability of the mattress.

[0009] Preferably, the upper and / or lower mesh fabrics are hexagonal or quadrangular warp knitted mesh fabrics. Hexagonal warp knitted mesh fabrics, due to their unique hexagonal mesh structure, offer greater structural stability and strength than quadrangular mesh fabrics. This stability helps resist deformation under external forces, thereby extending the service life of the 3D material.

[0010] Preferably, the support wires at opposite ends of the 3D material have opposite bending directions. Support wires with opposite bending directions can better disperse pressure.

[0011] Preferably, the support filaments have a diameter of 0.25-3 mm. Compared to the approximately 0.16-0.18 mm diameter support filaments used in existing 3D materials, the increased diameter of the support filaments allows the high-viscosity polyester material more time to react when heated. The longer the reaction time, the more opportunities for molecular chains to rearrange and crosslink, resulting in an increase in molecular weight and viscosity, making it less susceptible to deformation due to temperature changes.

[0012] Preferably, the lower mesh fabric is woven from composite braided yarns, and the upper mesh fabric is woven from single braided yarns. The lower mesh fabric is hardened, while the upper mesh fabric can still be used as a normal surface, making it easier to apply the 3D material to the top layer of the mattress.

[0013] A mattress comprises the above-mentioned 3D material.

[0014] This utility model has the following beneficial effects: the addition of hot-melt yarn to the composite braid significantly enhances the structural stability of the material. The hot-melt yarn melts at high temperatures and bonds to the yarn, forming a tighter and stronger braided structure that effectively resists deformation. The addition of hot-melt yarn not only enhances the structural strength of the material but also improves its durability. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The following is a further detailed description of the specific implementation of the present invention in conjunction with the accompanying drawings to make the technical solution of the present invention easier to understand and grasp. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0020] This embodiment provides a mattress, including a 3D material that resists deformation, which is a specific application of the 3D material of the utility model on a mattress. Figure 1 As shown, the anti-deformation 3D material includes an upper mesh cloth 100, a lower mesh cloth 200 and a support wire 300 connected between the upper mesh cloth 100 and the lower mesh cloth 200, and at least one layer of the upper mesh cloth 100 and the lower mesh cloth 200 is woven from a composite braided wire, and the composite braided wire includes a yarn 210 and a hot-melt yarn 220 attached to the yarn 210.

[0021] The addition of hot-melt yarn 220 significantly enhances the structural stability of the composite braided yarn. Hot-melt yarn 220 melts at high temperatures and bonds to yarn 210, forming a tighter and stronger braided structure that effectively resists deformation. The addition of hot-melt yarn 220 not only strengthens the material's structural strength but also improves its durability.

[0022] The composite braided cord is resistant to breakage and maintains its shape and performance even under frequent use or high pressure. This means that when used in mattresses, the lifespan of the mattress will be significantly extended, reducing the frequency and cost of mattress replacements.

[0023] Despite the addition of the hot melt yarn 220, the composite braid retains the breathability of the mesh. The bonding effect of the hot melt yarn 220 does not completely seal the mesh, so the mattress still has good breathability. This helps keep the mattress interior dry and clean, reducing the growth of bacteria and mold, and maintaining a hygienic and healthy mattress.

[0024] The use of composite braided yarns makes the processing of 3D materials more flexible and convenient. Parameters such as the material, diameter, and weaving method of yarn 210 and hot-melt yarn 220 can be adjusted to meet different needs and design requirements. This provides more possibilities for customized mattress production, meeting the diverse needs of consumers.

[0025] like Figure 3 As shown, the yarn 210 and the hot-melt yarn 220 are intertwined and twisted together. This physical interweaving not only increases the overall strength of the material but also strengthens the bond between the yarn 210 and the hot-melt yarn 220. This tightly bound structure effectively resists deformation when subjected to external forces, maintaining the material's shape.

[0026] like Figure 1 As shown, the support filaments 300 are C-shaped. These C-shaped support filaments 300 provide enhanced support. When the 3D material is subjected to pressure, the C-shaped support filaments 300 more effectively disperse the pressure, reducing single-point pressure and thereby enhancing the support of the 3D material. Numerous tiny gaps are formed between the C-shaped support filaments 300, which facilitate air circulation and improve the breathability of the mattress.

[0027] like Figure 1 、 2 As shown, the upper mesh fabric 100 and the lower mesh fabric 200 are hexagonal warp knitted mesh fabrics. Due to its unique hexagonal mesh structure, hexagonal warp knitted mesh fabrics offer greater structural stability and strength than mesh fabrics with other shapes, such as square or triangular. This stability helps resist deformation under external forces, thereby extending the service life of the 3D material. In other optional embodiments, one of the upper mesh fabric 100 and the lower mesh fabric 200 may be a hexagonal warp knitted mesh fabric, while the other may be a square warp knitted mesh fabric.

[0028] Furthermore, the support wires 300 at opposite ends of the 3D material have opposite bending directions. The support wires 300 with opposite bending directions can better disperse pressure. In other optional embodiments, the support wires 300 at opposite ends of the 3D material can also have the same bending direction.

[0029] Furthermore, the support filaments 300 have a diameter of 0.25-3 mm, for example 0.28 mm. Compared to the approximately 0.16-0.18 mm diameter of the support filaments 300 in existing 3D materials, the increased diameter of the support filaments 300 allows the high-viscosity polyester material more time to react when heated. The longer the reaction time, the more opportunities for molecular chains to rearrange and crosslink, resulting in an increase in molecular weight and viscosity, making it less susceptible to deformation due to temperature changes.

[0030] In this embodiment, the lower mesh fabric 200 is woven from composite yarn, while the upper mesh fabric 100 is woven from a single yarn. While the lower mesh fabric 200 undergoes a hardening treatment, the upper mesh fabric 100 remains functional, facilitating the application of 3D materials on the top layer of the mattress. In other alternative embodiments, both the upper and lower mesh fabrics 100, 200, can be woven from composite yarn, or only the upper mesh fabric 100 can be woven from composite yarn.
