Description

Technical Field

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

[0002] Curtains are fabrics used to cover windows, usually hanging above them. They can be made of various fabrics and are used to block outside views, block strong light, and protect privacy. They can not only effectively regulate the intensity of indoor light, making the indoor environment more comfortable, but also block outside noise to a certain extent, enhancing the tranquility of living.

[0003] Nonwoven fabric is a nonwoven material, with polypropylene being one of the main raw materials. It has the characteristics of short process flow, fast production speed, high output, light weight, softness, low cost, wide application and multiple raw material sources. These characteristics make nonwoven fabric an ideal material for curtain manufacturing.

[0004] Meanwhile, the design and manufacturing technology of non-woven curtains is constantly developing and improving. By adopting advanced production processes and technologies, non-woven curtains with better performance and appearance can be produced, such as better waterproof performance, better light transmission, and greater aesthetics. These technological advancements have further promoted the application and development of non-woven curtains in the market.

[0005] However, due to the high thermal conductivity of polypropylene nonwoven fabric and the lack of an effective insulation layer, heat can easily penetrate it, and its effect of blocking outdoor heat radiation in summer is limited, thus affecting indoor temperature control. Summary of the Invention

[0006] To overcome the shortcomings of the prior art, this utility model proposes a polypropylene nonwoven fabric, comprising several nonwoven fabric units stacked vertically in sequence, the several nonwoven fabric units being combined to form a nonwoven fabric curtain body, each nonwoven fabric unit consisting of two symmetrically arranged nonwoven fabric slats with a V-shaped cross section, each nonwoven fabric unit having an air storage hole penetrating through it, and each air storage hole being provided with a heat insulation component to enhance heat insulation.

[0007] To achieve the above objectives, several nonwoven fabric units are combined to form the nonwoven curtain body, which facilitates the folding and unfolding of the nonwoven curtain body. When the nonwoven curtain body is folded, the footprint is reduced and several air storage holes are folded. When the nonwoven curtain body is unfolded, several air storage holes are exposed. At this time, by preventing heat insulation components inside the air storage holes, an air insulation layer is formed, which effectively blocks heat transfer.

[0008] Furthermore, the heat insulation component includes a heat insulation core board adapted to the size of the air storage hole, the heat insulation core board being inserted into the air storage hole and connected to the non-woven curtain body, the heat insulation core board being made of polystyrene foam board.

[0009] Furthermore, the heat insulation core board has a number of through holes evenly distributed throughout, and the number of through holes are arranged in an array along the long side of the heat insulation core board.

[0010] Furthermore, rubber sheets are fixed at both ends of the outer wall of the heat insulation core plate, and the rubber sheets abut against the ends of the air storage holes.

[0011] Furthermore, an aluminum foil layer is bonded to one side of the nonwoven curtain body.

[0012] Furthermore, each of the nonwoven fabric slats extends upward at its upper end and downward at its lower end. The extension ends of every two adjacent nonwoven fabric slats are fixedly connected as a joining line, and the joining line positions of every two adjacent nonwoven fabric units are fixedly connected.

[0013] In summary, the polypropylene nonwoven fabric has the following beneficial effects: several nonwoven fabric units are combined to form the nonwoven curtain body, which facilitates the folding and unfolding of the nonwoven curtain body. When the nonwoven curtain body is folded, the space occupied is reduced. Several air storage holes are folded. When the nonwoven curtain body is unfolded, several air storage holes are exposed. At this time, by preventing the heat insulation components in the air storage holes, an air heat insulation layer is formed, which effectively blocks the heat transfer. Attached Figure Description

[0020] The technical solution of this utility model will be more clearly and completely explained below with reference to the accompanying drawings and through the description of the preferred embodiments of this utility model.

[0021] like Figure 1-4As shown, the preferred embodiment of this utility model is a polypropylene nonwoven fabric, which includes several nonwoven fabric units 1-1 stacked vertically. The several nonwoven fabric units 1-1 are combined to form a nonwoven fabric curtain body 1. Each nonwoven fabric unit 1-1 is composed of two symmetrically arranged nonwoven fabric slats 1-2 with a V-shaped cross section. The upper end of each nonwoven fabric slat 1-2 extends upward and the lower end extends downward. The extended ends of every two adjacent nonwoven fabric slats 1-2 are fixedly connected as a joint line. The joint line positions of every two adjacent nonwoven fabric units 1-1 are fixedly connected. The several nonwoven fabric units 1-1 are combined to form a nonwoven fabric curtain body 1, so as to facilitate the folding and unfolding of the nonwoven fabric curtain body 1.

[0022] like Figure 2 and 3 In order to improve the heat insulation effect of the non-woven curtain body 1, each non-woven unit 1-1 is provided with an air storage hole 2. Each air storage hole 2 is provided with a heat insulation component 3 to enhance heat insulation. The heat insulation component 3 includes a heat insulation core board 301 that is adapted to the size of the air storage hole 2. The heat insulation core board 301 is inserted into the air storage hole 2 and connected to the non-woven curtain body 1. The heat insulation core board 301 is made of polystyrene foam board.

[0023] like Figure 1 and Figure 2 and Figure 3 Before folding the non-woven curtain body 1, the heat insulation core board 301 inside the air storage hole 2 is removed. When the non-woven curtain body 1 is folded, the space occupied is reduced, and several air storage holes 2 are folded. When the non-woven curtain body 1 is unfolded, several air storage holes 2 are exposed. When heat insulation is required, the heat insulation core board 301 is inserted into the air storage hole 2 to block a large amount of heat radiation and enhance the heat insulation effect of the non-woven curtain body 1. The heat insulation core board 301 is connected to the non-woven curtain by plugging and unplugging, which facilitates the disassembly and replacement of the heat insulation core board 301 and does not affect the folding of the non-woven curtain. The heat insulation core board 301 is made of polystyrene foam board, which has the characteristics of being lightweight while providing heat insulation.

[0024] like Figure 3 and Figure 4 The heat insulation core board 301 has several through holes 302 evenly distributed. The through holes 302 are arranged in an array along the long side of the heat insulation core board 301. By opening several through holes 302 on the heat insulation core board 301 to store air, a natural heat insulation barrier is formed, which effectively blocks solar radiation heat. At the same time, it greatly reduces the overall weight and reduces the possibility of deformation of the non-woven curtain body 1 due to excessive weight.

[0025] like Figure 3 and Figure 4Rubber sheets are fixed at both ends of the outer wall of the heat insulation core board 301, and the rubber sheets abut against the ends of the air storage hole 2. The rubber sheets fixed at both ends of the heat insulation core board 301 increase the friction between the heat insulation core board 301 and the non-woven fabric curtain body 1, reducing the possibility of the heat insulation core board 301 detaching from the air storage hole 2. When removing the heat insulation core board 301, the user needs to slowly lift the heat insulation core board 301 so that the rubber sheets on the heat insulation core board 301 are disconnected from the wall of the air storage hole 2 so that the heat insulation core board 301 can be removed.

[0026] like Figure 1 and Figure 2 An aluminum foil layer is bonded to one side of the non-woven curtain body 1. By setting an aluminum foil layer on one side of the non-woven curtain body 1, more than 80% of solar radiation heat is reflected, further improving the heat insulation effect of the device.

[0027] The above-described specific embodiments are merely preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Various modifications, substitutions, and improvements made by those skilled in the art to the technical solutions of the present invention based on the provided description and drawings, without departing from the design concept and spirit of the present invention, should all fall within the scope of protection of the present invention. The scope of protection of the present invention is determined by the claims.
