Description

Technical Field

[0001] This utility model relates to the field of knitted fabric technology, and in particular to a light-blocking and breathable knitted fabric. Background Technology

[0002] The main functions of blackout breathable knitted fabric include shading, breathability, and light regulation. This material, by incorporating a blackout layer into the knitted fabric, effectively blocks light penetration, protecting privacy and reducing the harmful effects of ultraviolet rays. Simultaneously, the breathable design of the knitted fabric allows outside air to enter through ventilation openings, ensuring indoor air circulation and solving the problem of traditional blackout curtains hindering airflow. Blackout breathable knitted fabric can be used to make curtains and blackout clothing, protecting privacy while maintaining indoor air circulation. For outdoor activities, this material can be used to make tents, parasols, etc., providing both sun protection and breathability, making it suitable for various outdoor activities.

[0003] Existing methods involve using breathable materials to create knitted fabrics that ensure light blocking while maintaining good breathability. This application provides an alternative technical solution to address this problem. Utility Model Content

[0004] The purpose of this invention is to overcome the aforementioned problems in traditional technologies and provide a light-blocking and breathable knitted fabric.

[0005] To achieve the above-mentioned technical objectives and effects, this utility model is implemented through the following technical solution:

[0006] A light-blocking and breathable knitted fabric includes a base layer, which is composed of an outer breathable layer, a first light-blocking fabric layer, a second light-blocking fabric layer, and an inner breathable layer bonded together in sequence.

[0007] The outer breathable layer and the inner breathable layer each have several rows of first breathable holes for ventilation, and the first breathable holes are cylindrical holes.

[0008] The first light-shielding fabric layer has several rows of second ventilation holes evenly distributed on it. The second ventilation holes are composed of a first arc-shaped groove, a rectangular groove and a second arc-shaped groove from the outside to the inside.

[0009] The second light-shielding fabric layer has several rows of third ventilation holes evenly distributed on it. The third ventilation holes are composed of a third arc-shaped groove and a V-shaped groove with the tip pointing upward, from the outside to the inside.

[0010] The second vent and the corresponding third vent form a connected light-extinguishing venting channel.

[0011] Furthermore, in the aforementioned light-blocking and breathable knitted fabric, the density of the first air pores in the outer breathable layer is greater than the density of the second air pores in the first light-blocking fabric layer, the maximum width of the first arc-shaped groove is greater than the spacing between two adjacent rows of first air pores, and at least one row of first air pores in the outer breathable layer is connected to the first arc-shaped groove of the second air pores in the first light-blocking fabric layer.

[0012] Furthermore, in the aforementioned light-blocking and breathable knitted fabric, the first air vent in the inner breathable layer is interconnected with the opening on the corresponding side of the V-shaped groove in the second light-blocking fabric layer.

[0013] Furthermore, in the above-mentioned light-blocking and breathable knitted fabric, the width of the rectangular groove in the second air vent is less than the maximum width of the first or second arc-shaped groove, and the maximum width of the second arc-shaped groove is equal to the maximum width of the third arc-shaped groove.

[0014] Furthermore, in the above-mentioned light-blocking and breathable knitted fabric, the included angle of the V-shaped groove is 45 to 60 degrees.

[0015] Furthermore, in the aforementioned light-blocking and breathable knitted fabric, both the outer and inner breathable layers are woven from yarns using a rib knit structure, and the yarns are formed by twisting polyester and spandex fibers.

[0016] The beneficial effects of this utility model are:

[0017] This utility model provides a light-blocking and breathable knitted fabric, which is mainly composed of an outer breathable layer, a first light-blocking fabric layer, a second light-blocking fabric layer, and an inner breathable layer bonded together. The outer and inner breathable layers each have several rows of first air vents for ventilation. The second air vents of the first light-blocking fabric layer and the corresponding third air vents of the second light-blocking fabric layer form a connected light-extinguishing and breathable channel. Outside air can enter the light-extinguishing and breathable channel through the first air vents of the outer breathable layer and finally enter the room through the first air vents of the inner breathable layer. It also passes through the light-extinguishing and breathable channel in different directions to reduce direct light, thus achieving good breathability while providing light blocking.
