Technical Field

[0001] The utility model relates to the technical field of coated fabrics, in particular to a tear-resistant PVC coated fabric. Background Art

[0002] PVC coated fabric is a kind of fabric with a layer of PVC (polyvinyl chloride) material coated on its surface. This coating can endow the fabric with various excellent properties, such as waterproof, moisture-proof, anti-corrosion, wear-resistant, etc., and is widely used in various fields, such as construction, automobiles, ships, furniture, etc. Among them, awning fabric or partition fabric is one of the important application directions of PVC coated fabric.

[0003] Traditional PVC coated awning fabric or PVC coated partition fabric is generally used for covering or wrapping goods during transportation to provide protection for the goods and ensure that they will not be damaged during the transportation process. For some high-load and high-intensity work, the used PVC coated awning fabric or PVC coated partition fabric should have good tensile and anti-tearing properties. However, the anti-tearing structure of traditional PVC coated fabric is relatively simple, and the anti-tearing performance is average.

[0004] Therefore, it is necessary to design a tear-resistant PVC coated fabric. Summary of the Utility Model

[0005] In order to overcome the disadvantages that for some high-load and high-intensity work, the used PVC coated awning fabric or PVC coated partition fabric should have good tensile and anti-tearing properties, while the anti-tearing structure of traditional PVC coated fabric is relatively simple and the anti-tearing performance is average, the technical problem is: to provide a tear-resistant PVC coated fabric.

[0006] The technical solution is: a tear-resistant PVC coated fabric, including: a base fabric layer, a horizontal strengthening layer, a connecting layer, a glass fiber layer, a vertical strengthening layer and a PVC coating. Connecting layers are provided on both sides of the horizontal strengthening layer. The two sides of the base fabric layer are symmetrically provided with connecting layers to connect with the horizontal strengthening layer. Glass fiber layers are provided on the connecting layers of the two horizontal strengthening layers that are not connected to the base fabric layer. Connecting layers are provided on both sides of the vertical strengthening layer. One side of the glass fiber layer away from the horizontal strengthening layer is connected to the vertical strengthening layer through a connecting layer. One side of the vertical strengthening layer away from the horizontal strengthening layer is connected with a PVC coating through a connecting layer; both the horizontal strengthening layer and the vertical strengthening layer are structures with long rubber strips evenly spaced and embedded in the upper and lower sides of the fabric. The horizontal strengthening layer is horizontally and transversely embedded, and the vertical strengthening layer is horizontally and longitudinally embedded.

[0007] Further, the interval between the rubber strips on the same side of the upper and lower sides of the horizontal strengthening layer and the vertical strengthening layer is the width of one rubber strip.

[0008] Further, the connecting layer is woven from elastic yarn and only covers a thin layer on the surface of the horizontal strengthening layer or the vertical strengthening layer to make the surface of the horizontal strengthening layer or the vertical strengthening layer flat.

[0009] Further, the glass fiber layer has a grid structure and is connected to the transverse strengthening layer and the longitudinal strengthening layer by sewing.

[0010] Further, protrusions are sewn at the positions where the connection layer on the side of the longitudinal strengthening layer away from the transverse strengthening layer contacts the PVC coating.

[0011] The beneficial effects of the present utility model are as follows: In the present utility model, the transverse strengthening layer and the longitudinal strengthening layer are superimposed on the base fabric, and then the entire coated fabric is reinforced by the horizontally and vertically superimposed long rubber strips embedded in the transverse strengthening layer and the longitudinal strengthening layer. Moreover, a glass fiber layer is arranged between the transverse strengthening layer and the longitudinal strengthening layer, so as to thicken the base fabric while significantly improving the structural stability and strength of the present PVC coated fabric.

[0015] The preferred technical solutions of the present utility model will be described in detail below with reference to the drawings.

[0016] Embodiment 1

[0017] As Figure 1 and 2 shown, the present utility model provides a tear-resistant PVC coated fabric, which specifically includes a base fabric layer 1, a transverse strengthening layer 3, a connection layer 2, a glass fiber layer 4, a longitudinal strengthening layer 5, and a PVC coating 6;

[0018] Among them, connection layers 2 are provided on both sides of the transverse strengthening layer 3, and connection layers 2 are symmetrically provided on both sides of the base fabric layer 1 and are connected to the transverse strengthening layer 3 through the connection layers 2;

[0019] Among them, glass fiber layers 4 are provided on the connection layers 2 of the two transverse strengthening layers 3 that are not connected to the base fabric layer 1;

[0020] Among them, connection layers 2 are provided on both sides of the longitudinal strengthening layer. The sides of the glass fiber layers 4 away from the transverse strengthening layer 3 are all connected to the longitudinal strengthening layer through the connection layers 2, and the side of the longitudinal strengthening layer away from the transverse strengthening layer 3 is connected to a PVC coating 6 through a connection layer 2;

[0021] The horizontal reinforcement layer 3 and the vertical reinforcement layer are both structures in which long rubber strips are evenly spaced and embedded on the upper and lower sides of the fabric. The horizontal reinforcement layer 3 is horizontally and transversely embedded, and the vertical reinforcement layer is horizontally and longitudinally embedded. The intervals between the rubber strips on the upper and lower same sides of the horizontal reinforcement layer 3 and the vertical reinforcement layer are both the width of one rubber strip.

[0022] Exemplarily, in this coated fabric, by symmetrically stacking the horizontal reinforcement layer 3 and the vertical reinforcement layer on both sides of the base fabric, while thickening the base fabric, the entire coated fabric is reinforced by the horizontally and vertically stacked long rubber strips embedded in the horizontal reinforcement layer 3 and the vertical reinforcement layer, significantly improving the structural stability and strength of this PVC coated fabric 6, enhancing the tear resistance. Moreover, the glass fiber layer 4 between the horizontal reinforcement layer 3 and the vertical reinforcement layer has high strength in the 0-degree direction of the horizontal warp and weft main directions, which can further enhance the tear resistance of this PVC coated fabric 6. And the structure of setting long rubber strips at intervals up and down between the horizontal reinforcement layer 3 and the vertical reinforcement layer can embed as many long rubber strips as possible while maintaining the integrity of the reinforcement layer itself, ensuring the tear resistance of this PVC coated fabric 6.

[0023] The connecting layer 2 is woven from elastic yarn and only covers a thin layer on the surface of the horizontal reinforcement layer 3 or the vertical reinforcement layer, making the surface of the horizontal reinforcement layer or the vertical reinforcement layer flat.

[0024] The connecting layer 2 woven from elastic yarn has a certain elasticity, used to cover and connect the horizontal reinforcement layer 3 or the vertical reinforcement layer to form a structure of soft and hard multi-layer superposition, which can increase the tear resistance strength and the overall strength of the fabric.

[0025] The glass fiber layer 4 is a grid-shaped structure and is connected to the horizontal reinforcement layer 3 and the vertical reinforcement layer by sewing.

[0026] The grid-shaped glass fiber layer 4 can better adhere closely to the connecting layer 2 of the horizontal reinforcement layer 3 and the vertical reinforcement layer while saving raw materials, ensuring the tear resistance, and sewing together with the horizontal reinforcement layer 3 and the vertical reinforcement layer can ensure the stability of the connection.

[0027] At the position where the connecting layer 2 on the side of the vertical reinforcement layer away from the horizontal reinforcement layer 3 contacts the PVC coating 6, a protrusion is sewn.

[0028] The protrusion of the connecting layer 2 can make the PVC coating 6 better coated and fixed on the connecting layer 2.

[0029] The technical principles of the embodiments of the present utility model are described above in combination with specific embodiments. These descriptions are only for explaining the principles of the embodiments of the present utility model, and cannot be interpreted in any way as limiting the protection scope of the embodiments of the present utility model. Based on the explanations here, technicians in this field can think of other specific implementation methods of the embodiments of the present utility model without creative work, and these methods will fall within the protection scope of the embodiments of the present utility model.
