[0002] Traditional denim fabrics are made of cotton fibers. With the development of the times, various new raw materials are used in denim fabrics. Silk and linen are both natural fibers with excellent performance. Silk fabrics are soft, smooth, breathable and not stuffy. Linen fibers have excellent air permeability and moisture absorption, and also have antibacterial and deodorizing properties, making them suitable for use in light and thin fabrics in summer. The use of natural fibers with special functions in denim fabrics has great market prospects, but silk and linen blended fabrics have disadvantages such as easy wrinkling and poor strength. Utility Model Content

[0010] In some embodiments, the outer covering layer is a blended yarn formed by at least one of cotton fiber, tencel fiber and viscose fiber with silk and linen fiber; and / or, the weft yarn is a blended yarn formed by silk and linen fiber with cotton fiber.

[0011] In some embodiments, in the outer covering layer, the silk fiber accounts for 10% to 50%, the flax fiber accounts for 10% to 50%, and the total amount of the cotton fiber, tencel fiber and viscose fiber accounts for 30% to 70%.

[0012] In some embodiments, in the weft yarn, the silk fiber accounts for 10% to 50%, the flax fiber accounts for 10% to 50%; and the cotton fiber accounts for 30% to 70%.
