Fabric and preparation method thereof The application relates to a functional yarn, a preparation method thereof and a fabric, which are divisional patent applications of the application with the application date of 2023, 11, 24, the application number of 202311581459.0. Technical Field The invention relates to the technical field of textile, in particular to a fabric and a preparation method thereof. Background Studies have shown that excessive uv radiation is detrimental, and thus there is an increasing demand for anti-uv and cool feel functions in garment materials. Most yarns in the market at present have only a single function, such as ultraviolet resistance or cool feel. The existing ultraviolet-resistant fabric is generally thicker, is not in accordance with the use scene in summer, and in the environment with high temperature, the clothes can be stuffy when worn on the body, and the body can sweat greatly when worn on the body for a long time, so that the water loss of the human body is quickened, and the wearing experience of a user is reduced. In the preparation process of the existing light and thin sun-proof fabrics, after-finishing or film coating is needed, which can lead to the ultraviolet resistance of the fabrics to be greatly reduced after water washing. Disclosure of Invention In view of the above, in order to overcome the defects of the prior art, the invention aims to provide a fabric and a preparation method thereof, wherein the fabric woven by using functional yarns has a cool feel directly without after-finishing or film coating, and the ultraviolet resistance of the fabric is not affected.
