Description

Flame-retardant elastic mesh structure and manufacturing method thereof

The present invention relates to a flame-retardant elastic mesh structure and a method of manufacturing the same; In particular, it relates to an elastic mesh cloth which is used for a chair type product, which replaces a conventional seat cushion with an elastic mesh cloth, and a manufacturing method thereof.

The structure of the cloth with the chair is already very common. Technology, in recent years, the use of mesh cloth to replace the traditional densely woven fabrics, used in furniture, vehicles and other supplies on the chair, especially in contact with the human body, mainly provides cushioning, heat dissipation, ventilation, prevention of injury, and Improve the comfort of use; common forms of cushions such as seat cushions, cushions, guardrails, etc., instead of traditional materials with cushioning and elastic properties, such as air, liquid, foam, sponge, spring, etc.

In recent years, mesh fabrics have been made using elastic fiber weaving, such as China. Patent No. I324645 "elastic yarn and elastic net for chair", which is mainly composed of elastic layer of elastic mesh cloth formed by co-extrusion of core layer and surface layer, wherein the core layer and the surface layer are elastic materials of the same material, the core layer and The surface layer is a Thermoplastic Ester Elastomer (TPEE) elastic material of the same material, and the melting point of the core layer is higher than the melting point of the surface layer, wherein the thickness ratio of the core layer to the surface layer is 9:1 to 7:3, the core Layer The melting point is higher than the melting point of the surface layer, and the problem that the different materials of the core layer and the surface layer are peeled off for a long time can be solved, and the elastic yarn is woven into an elastic net for the chair, and when the user leaves the chair, the elastic cloth is very Quickly restore the original shape.

Another U.S. Patent No. 5,533,789 discloses a seat structure. A knitted fabric comprising an elastic weft inserted into the warp yarn forms a mesh-like support mesh surface, and the support mesh surface is used to form a seat support net and a back support net, and the tensile strength of the weft yarn is set to support the weight of the human body and provide comfort. degree.

In the related art disclosed in the related art, only the structure and manufacturing technology of the elastic yarn and the weaving structure of the mesh are disclosed. In view of the current market demand and safety requirements, the technical solution mainly solved by the present invention is to provide a use. The flame-retardant elastic mesh cloth of the seat and the manufacturing method thereof, the elastic mesh cloth is mainly based on the multi-strand multi-strand multifilament of the warp elastic monofilament weaving in the weft direction, and then the multifilament yarn passes through the warp elastic sheet The high-strength multifilament cross-weaving of silk and weft is used to enhance the combination of warp and weft with crossed multifilament to make the fabric of the warp fabric not easy to be deformed. The elastic monofilament is used to provide elastic function, and the strength of the high tensile multifilament provides support. After completion, the coiled elastic mesh cloth is released by the roller and is expanded by the roller pressure, and then enters the impregnation tank to impregnate the flame retardant flame retardant. During the impregnation process, the pressure is controlled by the roller, and after impregnation, The impregnated elastic mesh cloth is dried by a heating device, the flame retardant is combined with the elastic mesh cloth, and then wound up by a roller to become a flame-retardant elastic mesh cloth.

After the elastic mesh fabric of the complete manufacturing method of the present invention, the mesh fixing device of the chair can be utilized, for example, the upper frame is pressed or fixed or covered by a frame. The combination of mesh cloth and chair can be applied to the chair of traffic equipment, or the chair of indoor furniture, providing the support rigidity of the chair chair surface, replacing the elasticity of the seat cushion with elastic function, and having the function of ventilation, supplemented by The flame retardant function provides higher safety and can effectively enhance the industrial value of the chair.

The elastic mesh of the present invention is after being impregnated with a flame retardant Originally provided with the chair surface to support the occupant's weight, back support, or arm support and other basic functions, it also provides flexibility and comfort, the most important is to provide flame retardant effect, can make the chair indoors Or in the traffic appliance, when indoor or traffic equipment is burned, it will avoid causing multiple injuries to the user due to the flammability of the chair.
