Description

Technical Field

[0001] This utility model relates to the field of fabric technology, specifically to a cushion fabric. Background Technology

[0002] As people's requirements for seat cushion comfort, functionality, and environmental friendliness increase, the limitations of traditional seat cushion fabrics in terms of structural design and material application are becoming increasingly apparent.

[0003] Currently, most seat cushion fabrics on the market use static support structures such as sponges and springs, or simple flat woven mesh. These structures cannot dynamically adjust their support stiffness according to the distribution of body pressure and temperature changes. Prolonged sitting can easily cause soreness in the buttocks and lumbar spine areas where pressure is concentrated. Excessive stiffness in low temperatures reduces comfort, while a lack of rigid support in high temperatures can easily lead to posture deformation. Furthermore, to improve antibacterial effects, chemically synthesized antibacterial agents (such as quaternary ammonium salts and silver ion complexes) are added to the fabric. While these can inhibit bacteria in the short term, there is a risk of chemical residues, which can easily cause allergies upon skin contact, making them particularly unsuitable for sensitive groups such as infants and the elderly. Therefore, new technical solutions are needed to address these issues. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a cushion fabric to solve the technical problems that current cushion fabrics cannot dynamically adjust the support stiffness according to the distribution of human body pressure and temperature changes, thus affecting the comfort of sitting. In addition, although the addition of chemically synthesized antibacterial agents (such as quaternary ammonium salts and silver ion complexes) to the fabric can inhibit bacteria in the short term, there is a risk of chemical residue and poor safety.

[0005] To achieve the purpose of this utility model, the technical solution adopted by this utility model is as follows: design a cushion fabric, including: a support layer and an antibacterial layer arranged sequentially from bottom to top;

[0006] The support layer includes:

[0007] The honeycomb grid is woven from elastic memory fibers, and the honeycomb grid is hexagonal;

[0008] Silica aerogel microcapsules are filled into the cavities of the honeycomb grid.

[0009] Shape memory alloy micropillars are embedded at the nodes of a honeycomb grid;

[0010] The antibacterial layer is woven from konjac glucomannan antibacterial fibers, and nano-silver wires are mixed in the konjac glucomannan antibacterial fibers. The surface of the konjac glucomannan antibacterial fibers is coated with a titanium dioxide / graphene composite photocatalytic coating.

[0011] Preferably, the elastic memory fiber is a TPU-modified polyester fiber with a diameter of 0.4 mm and a honeycomb grid spacing of 2 mm.

[0012] Preferably, the shape memory alloy micropillar has a diameter of 1 mm, a phase transformation temperature range of 28-35℃, maintains flexibility at low temperatures, and hardens to form a rigid support point at high temperatures.

[0013] Preferably, the content of the silver nanowires in the antibacterial layer is 1%, the fiber diameter is less than 15 μm, and the surface of the contact layer is plasma-treated to form a skin-friendly interface with a contact angle of less than 60°.

[0014] Preferably, the silica aerogel microcapsules have a diameter of 200 μm, a wall thickness of 10 μm, and a porosity of ≥90%, and are fixed to the honeycomb grid wall by hot melt adhesive with a diameter of 0.5 mm.

[0015] Preferably, the konjac glucomannan antibacterial fiber is made by blending 79% konjac glucomannan and 20% polycaprolactone and spinning, with a fiber diameter of 10 μm.

[0016] Preferably, the support layer and the antibacterial layer are composited using a multi-layer co-weaving technique, with an overall thickness of 3 mm.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] 1. Dynamic pressure distribution: The hexagonal honeycomb mesh adapts to the human body's pressure, evenly bearing the pressure on the buttocks and lumbar spine, relieving soreness from prolonged sitting, and improving comfort during long-term use.

[0019] 2. Intelligent temperature regulation: Silica aerogel microcapsules combined with shape memory alloy micropillars maintain flexibility at low temperatures to avoid an overly hard feel, while high-temperature hardening provides rigid support, dynamically adapting to changes in ambient temperature and reducing the risk of posture deformation.

[0020] 3. Natural, safe, and antibacterial: Konjac glucomannan fiber blended with silver nanowires, along with a photocatalytic coating, achieves long-lasting antibacterial effects without the need for chemical antibacterial agents, eliminating the risk of residual allergies. Skin-friendly surface treatment further enhances its suitability for sensitive individuals.

[0021] 4. Structural optimization and synergy: Multi-layer co-woven technology combines the support layer and the contact layer. The 3mm thin design balances functional integration and portability. Elastic memory fiber ensures structural durability and breathability, achieving an organic unity of support and antibacterial properties. Attached Figure Description

[0025] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0026] Example 1: A cushion fabric, see [link to example]. Figures 1 to 2 The structure includes: a support layer 1 and an antibacterial layer 2 arranged sequentially from bottom to top. The support layer 1 and the antibacterial layer 2 are composited by multilayer co-weaving technology, with an overall thickness of 3mm. The support layer 1 includes: a honeycomb grid 11 woven from elastic memory fibers, and the honeycomb grid 11 is hexagonal; silica aerogel microcapsules 3, which are filled in the grid cavities of the honeycomb grid; and shape memory alloy micropillars 4, which are embedded at the nodes of the honeycomb grid 11. The antibacterial layer 2 is woven from konjac glucomannan antibacterial fibers 21, and the konjac glucomannan antibacterial fibers 21 are mixed with silver nanowires. The surface of the konjac glucomannan antibacterial fibers 21 is coated with a titanium dioxide / graphene composite photocatalytic coating. The konjac glucomannan antibacterial fibers 21 are made by blending 79% konjac glucomannan (KGM) and 20% polycaprolactone (PCL) and spinning, with a fiber diameter of 10μm.

[0027] During operation, the hexagonal honeycomb grid 11, woven from elastic memory fibers, can adaptively deform according to the pressure distribution of the human body, evenly distributing pressure on the buttocks and lumbar spine, effectively relieving soreness caused by concentrated pressure areas during prolonged sitting. The silica aerogel microcapsules 3 filled in the grid cavity can regulate the temperature inside the cushion, improving the situation of excessive hardness in low-temperature environments and lack of rigid support in high-temperature environments, thus enhancing comfort in different temperature environments. The shape memory alloy micropillars 4 embedded at the nodes of the honeycomb grid 11 can dynamically adjust the support stiffness according to temperature changes, further enhancing the cushion's ability to adapt to different environmental temperatures and human body pressure. The antibacterial layer 2 is woven from konjac glucomannan antibacterial fibers 21, which naturally have antibacterial properties. The blended nano-silver threads can work together to exert antibacterial effects, avoiding the chemical residue risks of traditional chemically synthesized antibacterial agents and reducing the possibility of skin allergies. It is especially suitable for sensitive groups such as infants, the elderly, etc. In addition, the titanium dioxide / graphene composite photocatalytic coating on the fiber surface can continuously exert its antibacterial effect under light conditions, thus prolonging the antibacterial duration.

[0028] For details, see Figure 2The elastic memory fiber is a TPU-modified polyester fiber with a diameter of 0.4mm. The honeycomb grid 11 has a spacing of 2mm. By using TPU-modified polyester fiber for the elastic memory fiber, it has good elasticity and memory function, which can better adapt to changes in human sitting posture. It can also quickly return to its original shape after long-term use, ensuring the stability and durability of the seat cushion support. Combined with the structural design of the honeycomb grid 11, the seat cushion has good breathability, which is conducive to air circulation and timely dissipation of heat and moisture generated by the human body, thus improving the comfort experience during use.

[0029] Further, see Figure 2 The shape memory alloy micropillars 4 have a diameter of 1mm and a phase transition temperature range of 28-35℃. They remain flexible at low temperatures and harden to form rigid support points at high temperatures. Because the shape memory alloy micropillars 4 have a specific phase transition temperature range, they remain flexible at low temperatures, ensuring that the seat cushion does not affect comfort due to excessive hardness in low-temperature environments. At high temperatures, they harden to form rigid support points, providing sufficient rigid support for the human body and preventing posture deformation caused by lack of rigid support in high-temperature environments. This achieves dynamic adjustment of the seat cushion's support stiffness with temperature changes, enhancing the seat cushion's applicability in different temperature environments.

[0030] It is worth noting that, see Figure 1 The nano-silver wires in the antibacterial layer 2 contain 1% of the nano-silver wires, with a fiber diameter of less than 15μm. The surface of the contact layer is plasma-treated to form a skin-friendly interface with a contact angle of less than 60°. The nano-silver wires blended in the antibacterial layer 2 combine with the konjac glucomannan antibacterial fiber 21 to exert a synergistic antibacterial effect, which can more effectively inhibit bacterial growth and does not rely on chemically synthesized antibacterial agents, thus fundamentally eliminating the risk of chemical residues and protecting the user's skin health. The small fiber diameter makes the contact layer softer and more delicate, making it more comfortable to fit the skin. The plasma-treated surface of the contact layer forms a skin-friendly interface, which improves the compatibility between the contact layer and the skin, reduces friction and irritation to the skin, and further enhances the skin-friendliness and comfort of the cushion, making it especially suitable for sensitive people.

[0031] It is worth noting that, see Figure 2 The silica aerogel microcapsules 3 have a diameter of 200 μm, a wall thickness of 10 μm, and a porosity of ≥90%. They are fixed to the wall of the honeycomb grid 11 with hot melt adhesive with a diameter of 0.5 mm. By fixing the silica aerogel microcapsules 3 to the wall of the honeycomb grid 11 with hot melt adhesive, the stable distribution of the microcapsules is ensured without affecting the elastic deformation ability and overall air permeability of the honeycomb grid 11. This allows the temperature regulation function to be organically combined with the adaptive support structure, further improving the comfort of use in different environments.
