Description

Technical Field

[0001] This invention belongs to the field of fleece technology, specifically relating to a tensile-resistant fleece and its manufacturing process. Background Technology

[0002] Fleece refers to cotton or polyester fabric with a pile on the surface. Through special processing, a soft and dense pile is formed on the surface of the fabric. This type of fabric is soft and skin-friendly, and has good warmth retention and comfort.

[0003] Patent CN217863159U discloses a heat-insulating fleece for electrical appliances. The fleece body includes a first heat-insulating component, a tensile component, and a second heat-insulating component. The tensile component comprises a first tensile layer, a second adhesive layer, and a second tensile layer. The second tensile layer is disposed above the first tensile layer and above the second adhesive layer. The second heat-insulating component is disposed below the first tensile layer and above the second tensile layer. Both the first and second heat-insulating components include a first heat-insulating layer, a first adhesive layer, and a second heat-insulating layer. The first heat-insulating layer is disposed above the first adhesive layer. Both the first and second tensile layers are made of spandex fibers. Made of woven fabric, the thermal insulation fleece for electrical appliances has excellent tensile properties due to the good tensile properties of spandex fibers. When using the thermal insulation fleece, the user applies glue to one side of the fleece, aligns it with the appliance, and then applies external force towards the appliance until the fleece is glued to the designated working position on the appliance. Although this patent improves tensile properties through spandex fibers, it still suffers from insufficient tensile strength. In addition, the fleece needs to be glued to the appliance surface during use, and frequent disassembly and reassembly not only easily leads to wear on the fleece surface but also reduces its service life. Summary of the Invention

[0004] The purpose of this invention is to provide a tensile-resistant fleece fabric and its manufacturing process, which improves the tensile strength and abrasion resistance of the fleece fabric, while simplifying the installation process and extending its service life.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a tensile-resistant fleece fabric, comprising a heat-insulating substrate, a tensile-resistant base layer disposed on the outside of the heat-insulating substrate, an antibacterial layer disposed on the outside of the tensile-resistant base layer, a polyamide fiber layer disposed on the outside of the antibacterial layer, wherein steel wires are embedded inside the polyamide fiber layer, and a wear-resistant fleece layer is disposed on the outside of the polyamide fiber layer.

[0006] As a preferred embodiment of the present invention, it further includes fasteners symmetrically arranged on the outer surface of the wear-resistant fleece layer, and connecting pieces arranged on the side surface of the fasteners.

[0007] As a preferred embodiment of the present invention, the fastener has a "U" shaped structure and a rectangular longitudinal section.

[0008] As a preferred technical solution of the present invention, it further includes a hook and loop fastener surface disposed at the bottom of the connecting piece, and the hook and loop fastener surface has a cuboid structure.

[0009] As a preferred technical solution of the present invention, it further includes a fixing block disposed at the bottom of the connecting piece, and the fixing block is a cylindrical structure.

[0010] This invention also discloses a manufacturing process for tensile-resistant fleece fabric, comprising the following steps: Raw material preparation Thermal insulation substrate: High-temperature resistant glass fiber or ceramic fiber materials with low thermal conductivity are selected and cut according to requirements; Tensile base layer: made of aramid fiber or carbon fiber, woven into a mesh or cloth after pretreatment; Polyamide fiber layer: Fine steel wires are evenly embedded in it to form a composite fiber layer; Antibacterial layer: Made of nano-sponge containing silver ions; Abrasion-resistant fleece layer: woven from nylon fibers; Multi-layer composite structure The thermal insulation substrate, tensile base layer, antibacterial layer, and polyamide fiber layer are stacked in sequence and initially fixed by hot pressing or sewing. A wear-resistant fleece layer is then covered on the polyamide fiber layer, and the layers are firmly bonded together by hot pressing or sewing to form a complete tensile fleece. Post-processing The composite tensile-resistant fleece is subjected to a shaping treatment to ensure the stability of its shape and size; Trim excess nap and edges, and smooth the surface of the velvet to make it flat and beautiful.

[0011] Compared with the prior art, the beneficial effects of the present invention are: By combining the tensile-resistant base layer and the polyamide fiber layer embedded with steel wires, the tensile-resistant fleece of the present invention has excellent tensile strength and tear resistance, which can meet the high requirements of electrical insulation protection. No glue is required; it can be easily installed on the surface of electrical appliances by mechanical fixing or Velcro, improving installation efficiency and convenience. The antibacterial layer design ensures the cleanliness and hygiene of the fabric, preventing bacterial growth and making it suitable for electrical appliance usage environments with high hygiene requirements.

The Velcro 610 on the connecting piece 61 is bonded to the Velcro 71 on the top of the support plate 7, so that the tensile-resistant velvet is firmly connected, improving installation efficiency and convenience.

[0018] A manufacturing process for a tensile-resistant fleece fabric includes the following steps: Raw material preparation Thermal insulation substrate 1: Select high temperature resistant and low thermal conductivity glass fiber or ceramic fiber material, and cut according to requirements; Tensile base layer 2: Made of aramid fiber or carbon fiber, woven into a mesh or cloth after pretreatment; Polyamide fiber layer 4: Fine steel wires are evenly embedded in it to form a composite fiber layer; Antibacterial layer 3: Made of nano sponge containing silver ions; Abrasion-resistant fleece layer 5: woven from nylon fibers; Multi-layer composite structure The heat insulation substrate 1, tensile base layer 2, antibacterial layer 3, and polyamide fiber layer 4 are stacked in sequence and initially fixed by hot pressing or sewing.
