Description

Technical Field

[0001] The utility model relates to the technical field of coated fabrics, in particular to an engineering PVC coated fabric. Background Art

[0002] Coated fabrics mainly refer to fabrics coated with a special functional material by a special process on the basis of the fabric, so that the fabric has special functions. Therefore, it is also called a functional coated fabric. PVC coated fabric is one of them. When used in the engineering field, such as construction engineering, civil engineering, mechanical engineering, etc., it is mainly for temporary shielding, waterproofing, dustproofing, etc.

[0003] At present, the PVC coated fabric used in engineering is generally used in an environment with more outdoor dust, or directly contacts with dust or crushed stone soil. Especially for some newly built buildings that need to avoid direct sunlight, it is covered to reduce the direct irradiation of ultraviolet rays. However, although the existing sunscreen fabrics that can be used in the construction site environment can block the sunlight, it still feels very stuffy, and it cannot well block the temperature irradiated by the sun.

[0004] Therefore, it is necessary to design an engineering PVC coated fabric that can be used for sunscreen in the construction site environment. Content of the Utility Model

[0005] In order to overcome the disadvantages that although the existing sunscreen fabrics that can be used in the construction site environment can block the sunlight, it still feels very stuffy, and it cannot well block the temperature irradiated by the sun, the technical problem is: to provide an engineering PVC coated fabric.

[0006] The technical solution of the utility model is: an engineering PVC coated fabric, comprising: a base fabric and a fiberglass layer, the fiberglass layer is fixedly arranged on one side of the base fabric by needle and thread interweaving; a PVC coating, the PVC coatings are arranged on the sides of the fiberglass layer and the PTFE film away from each other; a PTFE film, the PTFE film is compounded on the side of the base fabric layer away from the fiberglass layer.

[0007] Furthermore, it further comprises: holes evenly distributed and penetrating through the PVC coating.

[0008] Furthermore, it further comprises: the glass fibers of the fiberglass layer are interwoven in warp and weft and have a certain gap.

[0009] The beneficial effects are: 1. Polyester has excellent ultraviolet protection effect and low cost. The cotton has good air permeability, which can promote the circulation of air between the fabrics. By blending in the way of warp and weft interspersion, it can not only prevent ultraviolet rays but also be breathable.

[0010] 2. A glass fiber layer is compounded with the base fabric by means of needle and thread interweaving, avoiding the problem of poor air permeability caused by traditional gluing, not conflicting with the air permeability of the base fabric, and fixing the glass fiber layer on one side of the base fabric to provide heat insulation effect.

[0015] The utility model will be further described below with reference to the drawings and embodiments.

[0016] Embodiment 1

[0017] As Figures 1 to 3 shown, the utility model provides an engineering PVC-coated fabric, specifically including: a base fabric 1, a glass fiber layer 2, a PVC coating 3, and a PTFE film 4;

[0018] Among them, the glass fiber layer 2 is fixedly arranged on the lower layer of the base fabric 1 by needle and thread interweaving for isolating the downward transfer of heat;

[0019] Among them, a PTFE film 4 is compounded on the side of the base fabric layer away from the glass fiber layer 2, and the PVC coating 3 is arranged on the side of the glass fiber layer 2 and the PTFE film 4 away from each other for improving the temperature resistance and physical strength of the fabric.

[0020] In the present invention, the base fabric 1 is a woven fabric blended from polyester and cotton. The woven fabric has a tighter structure and a lower porosity than knitted fabric, and can prevent more sunlight from penetrating. The polyester has an excellent UV protection effect and is inexpensive. The cotton has good air permeability and can promote the circulation of air between fabrics. The base fabric 1 is blended by interlacing warp and weft to form the base fabric 1, which not only has the function of blocking ultraviolet rays but also has the function of air permeability. A glass fiber layer 2 is compounded on one side of the base fabric 1 by interlacing the base fabric 1 with needles and threads. The interlacing method avoids the problem of poor air permeability caused by traditional gluing and does not conflict with the air permeability of the base fabric 1. The glass fiber layer 2 is also fixed to one side of the base fabric 1. The glass fiber layer 2 is a material with poor thermal conductivity, which can play a good role in heat insulation and prevent the temperature of the outer side of the cloth from rising due to sun exposure and transferring the temperature to the inside. The PVC coating 3 can provide a certain sunshade and UV protection effect and is also very wear-resistant, which can increase the service life of the utility model. A PTFE membrane 4 is compounded on one side of the base cloth 1, and the side is set to the outside facing the sun. The PTFE membrane 4 has a waterproof and breathable effect. By compounding the membrane on one side of the base cloth 1 and setting the side where the membrane is located as the outer side, a waterproof effect can be achieved, which prevents rainwater from penetrating into the base cloth 1, resulting in poor water absorption and air permeability of the cotton, etc., thereby improving the waterproof performance of the cloth of the utility model and ensuring breathability.

[0021] Example 2

[0022] like Figure 3 As shown, based on Example 1, the PVC coating 3 has evenly distributed penetrating holes.

[0023] By evenly opening holes on the PVC coating 3, the wear resistance and durability of the PVC coating 3 are retained, and the air permeability of the PVC coating 3 is enhanced, so that it can better provide a more comfortable environment for workers in environments such as construction sites while ensuring the durability of the utility model.

[0024] like Figure 2 As shown, based on Example 1, the glass fibers of the glass fiber layer 2 are arranged in a warp and weft interlaced manner with certain gaps.

[0025] The structure of interweaving warp and weft and retaining gaps ensures that the glass fiber layer can have a good thermal insulation effect during use while ensuring the breathability of the coated cloth.

[0026] The above are only specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model can easily think of changes or substitutions, which should all be covered within the protection scope of the present utility model. Therefore, the protection scope of the present utility model should be subject to the protection scope of the claims.
