Technical Field

[0001] The utility model relates to the field of outdoor product fabrics, and particularly relates to a one-way visible anti-perspective fabric. Background Art

[0002] The mesh fabrics used in outdoor leisure products such as tents are required to be light and breathable. However, due to people's need for privacy and some special situations such as hunting tents, when looking from the outside into the tent, it is required that the people inside cannot be clearly seen, but when looking from the inside of the tent to the outside, it is required to be relatively clear. This requires the mesh fabric to have the function of one-way anti-perspective. Content of the Utility Model

[0003] The utility model aims to at least solve one of the technical problems in the above technologies to some extent. For this reason, the purpose of the utility model is to provide a fabric that is transparent in one direction and not easily transparent in the other direction.

[0004] To achieve the above object, an embodiment of the utility model provides a one-way visible anti-perspective fabric, which includes, arranged in sequence:

[0018] Reference Signs Explanation:

[0019] Reflective layer 1, Filling layer 2, Reinforcing layer 3. Detailed Embodiments

[0020] The embodiments of the present invention will be described in detail below. Examples of the embodiments are shown in the drawings, wherein the same or similar reference signs denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

[0021] In the present invention, since the relatively light - colored reflective layer reflects the external ambient light, and the filling layer is made of a material with a darker color to block the hollow of the reflective layer, during use, the external light is either reflected or absorbed by the filling layer, thus achieving a one - way weakening of the light - transmission degree.

[0022] To better understand the above - mentioned technical solution, the exemplary embodiments of the present invention will be described in more detail below with reference to the drawings. Although the exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0023] To better understand the above - mentioned technical solution, the above - mentioned technical solution will be described in detail below in combination with the drawings of the specification and the specific embodiments.

[0024] Figures 1 to 4 A one - way visible anti - see - through fabric according to an embodiment of the present invention includes, in sequence:

[0025] Reflection layer 1: It is formed by a plain weave. Vertically, it consists of loop wales and floats of triangular-shaped polyester bright filaments. Horizontally, the same material is used to fully penetrate a multi-needle plain weave. The angle between the wales and floats of the horizontal structure is an acute angle.

[0026] The structure composed of polyester bright filaments. Since the triangular bright filaments can reflect the external light, it reduces the penetration of external light into the interior. Here, the interior refers to the internal space enclosed by the fabric. When in use, the reflection layer 1 is on the outside (such as the outer surface of a tent), and the other layers are arranged inside in sequence.

[0027] While providing the function of one-way light transmission, this fabric also provides functions of lightness and breathability, which is different from some existing fabrics with coatings or dense weaving structures. The latter can provide better light-shielding performance, but basically sacrifice breathability and it is difficult to achieve a light and thin effect.

[0028] Filling layer 2: It is formed by a weft insertion structure composed of polyester semi-dull filaments with a darker color than the reflection layer 1.

[0029] The reason for using the darker filling layer 2 is that, from the perspective of the vision of animals, a combination of light and dark makes it easier to notice the brighter part. For the finished product of this fabric, when viewed from a medium distance, it is a light-colored cloth with black dots. The visual intersection will gather on the light-colored part. Without the filling layer 2, it is possible to glimpse the internal space through the gaps between the reflection layer 1. Therefore, the function of the filling layer 2 is to control the visual focus on the fabric through artificially creating a contrast between light and dark, rather than converging behind the fabric.

[0030] Specifically, the angle between the wales and floats of the horizontal structure of the reflection layer 1 is 10 - 30°. At the micro level, this structure has no pattern compared with the vertical structure. Combined with the triangular-shaped bright filaments, it makes the light reflect multiple times at different angles in the structure, giving the reflection layer 1 a silver effect.

[0031] The loop wales and floats formed by the triangular bright filaments are used to reflect the external light, preventing the penetration of external light to the inside. At the same time, the multi-needle plain weave is applied to increase the horizontal density of the fabric. Due to the multi-needle plain weave, adjacent two needles are connected by multiple floats. In this way, the gap between adjacent two loops can prevent see-through, and several floats are evenly distributed on each loop wale to prevent see-through by the loop wales.

[0032] When some embodiments use the natural white full-drawn triangular-shaped polyester bright filaments with a size of 75 - 150D for the reflection layer 1, it is also possible to use the semi-drawn black polyester filaments with a size of 50 - 150D in combination with the filling layer 2, so that the fabric presents an overall silver-gray color perception, similar to the effect of other fabrics with coatings.

[0033] Reinforcement layer 3: It is composed of polyester filaments to form a tricot stitch. The loop stems of the reinforcement layer 3 are wound around the loop stems of the reflection layer 1, and the extension yarns of the reinforcement layer 3 are wound around the yarns of the filling layer 2. Specifically, the reinforcement layer 3 uses profiled round bright fully drawn polyester filaments with a size of 75 - 150D. By adopting this solution, the reflection of light in it is enhanced, and the extension yarns wind around the yarns of the filling layer 2 to reinforce it, preventing the filling layer 2 from shifting out of place.

[0034] This fabric is a warp-knitted mesh structure. The first layer is a reflective layer, and super bright yarns are selected to form the reflection layer 1. The second layer is a dark or black filling layer 2. The third layer is a reinforcement layer 3. The advantages are as follows: The three-layer structure is integrally formed, with a stable structure and high strength. The reflection layer 1 is used to reflect light and prevent external light from penetrating. The dark filling layer 2 in the middle further enhances the prevention of external light penetration. The reinforcement layer 3 of the third layer further stabilizes the structure and enhances the reflection effect. Multiple barriers prevent external light from entering and form a strong contrast between the internal and external light. At the same time, the warp-knitted mesh structure is beneficial for ventilation and visibility from the inside to the outside, and the gram weight is between 90g / m2 and 150g / m2.
