In order to improve the shading effect, the thickness and weaving density of knitted fabrics are usually increased, or chemical fibers with good shading effects are used for weaving. However, while conventional methods improve the shading properties of knitted fabrics, the air permeability will decrease, making the fabric easily feel stuffy when worn, affecting the use effect.
