[0002] With the improvement of people's living standards, the consumption concept is also upgraded, and the demand for products not only meets high quality, but also chases products with novel functionality. The emergence of one-way perspective material meets the increasing new needs of high-end market and consumers. The existing one-way perspective material is usually a woven fabric. The woven fabric is a fabric formed by interweaving yarns of two systems according to certain rules. Because the warp and weft yarns are independent of each other, when the fabric is deformed under external tension, the corresponding weft and warp yarns do not convert each other.
[0003] The one-way perspective material of the woven fabric relies on coating or composite and raw materials to achieve external shading. In order to ensure the internal light transmission, the material needs to be made light and thin. Such one-way perspective material not only has poor elasticity and high processing difficulty, but also has poor air permeability in use.
[0004] And as a kind of knitted fabric, warp knitting fabric is very suitable for producing one-way perspective material due to its characteristics of weaving method. The fabric performance is between woven fabric and weft knitting fabric, with good dimensional stability, anti -shedding, elasticity and air permeability, etc. Even if the fabric is very thick, the weaving structure can still ensure high light transmission.

[0023] The preferred embodiments of the utility model are described below in conjunction with the drawings, and it should be understood that the preferred embodiments described here are only used to illustrate and explain the utility model, and are not used to limit the utility model.
[0024] Embodiment: as Figures 1-2 Indicated, a kind of new one-way perspective material, including warp-knitted base cloth 1, two sides of the base cloth 1 are fabric loop surface and extension line surface respectively, two sides of the base cloth 1 are woven by high reflectance yarn 2 and low reflectance yarn 3 respectively, the base cloth 1 adopts warp-knitted composite pattern design, two sides of the base cloth 1 are dense structure and mesh structure respectively, provide structural basis for the realization of the one-way perspective functionality of the base cloth 1.
[0025] High reflectance yarn 2 is located in the extension line surface of base cloth 1, and low reflectance yarn 3 is located in the fabric loop surface of base cloth 1.
[0026] The extension line surface of base cloth 1 is light-reflecting surface, and the fabric loop surface of base cloth 1 is light-reflecting surface.
[0027] As Figures 3-4 Indicated, extension line surface is dense structure, beneficial to the reflection of light, and fabric loop surface is mesh structure, beneficial to the transmission of light.
[0028] When light passes through medium, its transmittance (T), reflectivity (R) and absorptivity (A) follow the law of conservation of energy:
[0029] Transmittance (T)+Reflectivity (R)+Absorptivity (A)=100%
[0030] Transmittance is the percentage of light flux when light transmits through medium and its incident light flux, and the higher the transparency of transparent medium (or the thinner the non-transparent medium), the easier light transmits through medium. In order to improve the transmittance of transparent medium, large-bright polyester FDY silk without TiO2 is selected and woven into mesh aperture to form a thin layer, and in order to reduce the transmittance of non-transparent medium, full-dull polyester fine denier fiber DTY silk with high proportion of TiO2 is selected and woven into mesh structure to form a thick layer
[0031] Reflectivity is the percentage of the light flux reflected by the medium after the light is incident on the medium, and the reflectivity increases with the increase of the difference of the refractive index of the two media, and the refractive index of the air medium is usually 1. In order to realize the difference of the double-sided reflectivity, the large-brightness polyester FDY yarn without TiO2 and the full-dull polyester fine denier fiber DTY yarn with high proportion of TiO2 are designed on the two sides of the fabric respectively, and they do not affect each other.
[0032] Absorptivity is the percentage of the light energy absorbed by the medium to the total light energy, and the absorptivity increases with the decrease of the transparency of the material. Because of the selection of the raw material, the transparency of the medium on the back light side is obviously lower than that on the light side, so the absorptivity of the light on the back light side is higher, and the light transmittance of the light on the back light side is also reduced, which promotes the one-way perspective effect.
[0033] The new one-way perspective material utilizes the reflection and transmission principles of light, with the extended line surface as the light side and the fabric loop surface as the back light side. When the incident light is shot to the mesh area corresponding to the high reflectivity yarn 2, partial reflection and partial transmission occur due to the "thin" and "sparse" of the area, and at the same time, when the incident light is shot to the non-mesh area, only reflection occurs due to the "thick" and "dense" of the area. The reflected light superimposes each other, affecting the weak light transmitted from the back light side of the base fabric 1, i.e. the light side cannot see the things on the back light side, while the back light side can see the things on the light side due to the transmitted light 1, thereby realizing the one-way perspective function in vision.
[0034] The raw material fineness of the base fabric 1 ranges from 15D to 600D, and the raw material hole number of the base fabric 1 ranges from 1F to 20000F.
[0035] The raw material of the fabric loop surface of the base fabric 1 is preferably full-dull polyester fine denier fiber DTY yarn with fineness of 75D and hole number of 72F, which has a lower reflectivity and a mesh structure. The raw material of the extended line surface of the base fabric 1 is preferably large-brightness polyester FDY yarn with fineness of 60D and hole number of 36F, which has a higher reflectivity and a dense structure.
[0036] The base fabric 1 is preferably designed by using single needle bed four comb complex pattern, utilizing three kinds of organization modes of chain stitch organization, weft insertion organization and changed satin organization for composite design, and combining GB1 full threading and GB2 / GB3 / GB4 partial empty threading threading mode to complete the development.
[0037] Working principle: the new one-way perspective material, in use, with the extended line surface as the light side, the fabric loop surface as the back light side, when the incident light is shot to the mesh area corresponding to the high reflectivity yarn 2, partial reflection and partial transmission occur due to the thin and sparse of the area, and at the same time, when the incident light is shot to the non-mesh area, only reflection occurs due to the thick and dense of the area, the reflected light is superimposed on each other, affecting the weak light transmitted from the back light side of the base cloth 1, that is, the light side cannot see the things on the back light side, while the back light side can see the things on the light side due to the transmitted light 1, thereby realizing the one-way perspective function in vision.
[0038] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and not for limiting the present application, although the foregoing embodiments of the present application have been described in detail, for those skilled in the art, it still can be modified, or part of the technical features of the equivalent replacement. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
