Description

Technical Field

[0001] This application relates to the field of warp-knitted flexible composite materials technology, and in particular to an anti-creep fabric and its preparation method. Background Technology

[0002] With the accelerating pace of life and the increasing need for spiritual enrichment, physical and mental health has become a topic of growing concern. Meanwhile, massage chairs with rehabilitation and health-preserving functions are becoming increasingly well-known. Massage can promote blood circulation, repair soft tissue adhesions, stimulate bone growth, regulate endocrine disorders, and improve cerebral cortex function and brain microcirculation.

[0003] Massage chairs are commonly found in shopping malls, office buildings, and residences, and are used by a wide range of people. They can replace physical labor by providing a series of acupressure massages, and are increasingly accepted by many. However, due to the nature of massage chairs, the materials used in them will undergo creep during prolonged use, resulting in unsightly deformation and even damage, posing a threat to personal safety. Therefore, it is necessary to research flexible composite materials with excellent creep resistance and analyze their mechanical properties.

[0004] Aramid fiber is a type of polyamide fiber composed of aromatic groups. In its molecular structure, all aromatic groups are linked to amide groups, giving aramid fibers low density, high tensile modulus, and good creep resistance. Furthermore, due to its relatively low chemical reactivity, aramid fiber exhibits strong flame retardancy, high temperature resistance, and corrosion resistance. These advantages have led to its widespread application in numerous industries worldwide. Initially, aramid fiber was used as a reinforcing material for epoxy resins, producing high-strength composite materials for applications in aerospace equipment, military supplies, and shipbuilding.

[0005] Therefore, this application uses aramid fibers in seat fabrics to improve the creep properties of current massage chair fabrics, enhance the long-term usability and safety of the materials, and has a wide range of applications. Summary of the Invention

[0009] The fabric layer is an aramid warp-knitted fabric, which includes a first group of fiber components and a second group of fiber components. The first group of fiber components and the second group of fiber components are woven together to form at least one of a double warp plain weave structure, a warp velvet weave structure, and a warp twill weave structure.

[0010] A resin coating is sprayed onto the fabric layer;

[0011] The resin coating comprises the following components:

[0012] Resin, 100 parts by weight;

[0013] Plasticizer, 1-3 parts by weight;

[0014] Crosslinking agent, 1 part by weight;

[0015] Foaming agent, 0.5-1 parts by weight;

[0018] In one possible implementation, the aramid warp-knitted fabric has a thickness of 0.6-0.7 mm and a basis weight of 160-210 g / m². 2 .

[0019] Secondly, this application provides a method for preparing an anti-creep fabric, the method being used to prepare an anti-creep fabric as described in any of the above-mentioned methods, the method comprising:

[0020] S1. After washing, vacuum drying, and heat setting, the aramid warp-knitted fabric is fixed flat on the needle plate frame to obtain the aramid warp-knitted base fabric.

[0021] S2. Plasticizer, crosslinking agent, foaming agent and flame retardant are added slowly and evenly to a container containing polyvinyl chloride resin. After magnetic stirring, a coating solution is obtained.

[0022] S3. The coating solution is evenly sprayed onto the aramid warp-knitted base fabric, and then subjected to hot pressing and heat curing treatment. Afterwards, it is vacuum dried at 80°C for 10-20 minutes and then placed in a ventilated place to air dry, thus obtaining the creep-resistant fabric.

[0023] In one possible implementation, in step S1: the vacuum drying temperature is 60-80℃ and the time is 1-4h.

[0024] In one possible implementation, in step S1: the temperature of the heat setting treatment is 200-280℃, and the time is 15-20 min.

[0025] In one possible implementation, step S2 specifically includes: magnetically stirring at a stirring rate of 100-300 r / min for 30-60 min under a temperature of 20-60°C.

[0026] In one possible implementation, step S3 specifically includes applying a pressure of 50-100 kPa at a temperature of 100-120°C for a hot-pressing time of 10-60 min.

[0028] Thirdly, this application provides an application of the anti-creep fabric according to any of the above descriptions in a massage chair.

[0029] The beneficial effects of the technical solution provided in this application include at least the following:

[0030] Aramid warp-knitted fabric is washed, vacuum-dried, and heat-set, then flattened and fixed on a needle plate to obtain an aramid warp-knitted base fabric. Plasticizer, crosslinking agent, foaming agent, and flame retardant are slowly and uniformly added to a container containing polyvinyl chloride resin. After magnetic stirring, a coating solution is obtained. The coating solution is uniformly sprayed onto the aramid warp-knitted base fabric, followed by hot-pressing and heat curing. After vacuum drying, it is removed and air-dried in a ventilated area to obtain an anti-creep fabric. In this process, the anti-creep fabric exhibits a transformation of filler from granular to two-dimensional sheet-like structure during isoaxial stretching and heat reshaping, forming an in-plane oriented structure. This results in the composite material possessing excellent anti-creep properties in all directions within the plane. Furthermore, this application utilizes a thermoplastic polymer as the matrix, and through heating and stress reshaping, preserves the microstructure of the material in a stretched state to a stress-free state, achieving a combination of flexibility and anti-creep properties in the knitted fabric.
