Description

Shading breathable knitted fabric Technical Field The utility model relates to the technical field of knitted fabrics, in particular to a shading breathable knitted fabric. Background The main functions of the shading breathable knitted fabric include shading, ventilation and light adjustment. The material can effectively block light penetration, protect privacy and reduce the damage of ultraviolet rays to human bodies by adding the shading layer into the knitted fabric. Meanwhile, due to the ventilation design of the knitted fabric, external air can enter through the ventilation opening, indoor air circulation is guaranteed, and the problem that the traditional window shade influences air circulation is solved. The shading breathable knitted fabric can be used for manufacturing curtains and shading clothes, so that privacy can be protected, and indoor air circulation can be kept. In outdoor activities, the shading breathable knitted fabric material can be used for manufacturing tents, sunshade umbrellas and the like, is shading and breathable, and is suitable for various outdoor activities. The existing knitted fabric is manufactured by using materials with good air permeability, so that the knitted fabric has good air permeability while light blocking is ensured. The application provides another technical scheme for solving the technical problem. Disclosure of utility model The utility model aims to overcome the problems in the prior art and provide a shading and ventilation knitted fabric. In order to achieve the technical purpose and the technical effect, the utility model is realized by the following technical scheme: The shading breathable knitted fabric comprises a base layer, wherein the base layer is formed by gluing an outer breathable layer, a first shading cloth layer, a second shading cloth layer and an inner breathable layer in sequence; The outer ventilation layer and the inner ventilation layer are respectively provided with a plurality of rows of first ventilation holes for ventilation, and the first ventilation holes are cylindrical holes; A plurality of rows of second ventilation holes for ventilation are uniformly distributed on the first shading cloth layer, and the second ventilation holes are sequentially formed by a first arc-shaped groove, a rectangular groove and a second arc-shaped groove from outside to inside; A plurality of rows of third ventilation holes for ventilation are uniformly distributed on the second shading cloth layer, and the third ventilation holes are sequentially formed by a third arc-shaped groove and a V-shaped groove with an upward tip from outside to inside; the second ventilation holes and the corresponding third ventilation holes form a light extinction ventilation channel which is communicated. Further, in the light-shielding breathable knitted fabric, the density of the first ventilation holes in the outer breathable layer is greater than the density of the second ventilation holes in the first light-shielding cloth layer, the maximum groove width value of the first arc-shaped grooves is greater than the distance value between two adjacent rows of the first ventilation holes, and at least one row of the first ventilation holes in the outer breathable layer is communicated with the first arc-shaped grooves of the second ventilation holes in the first light-shielding cloth layer. Further, in the light-shielding breathable knitted fabric, the first ventilation holes in the inner breathable layer are communicated with the openings on the corresponding sides of the V-shaped grooves in the second light-shielding cloth layer.
