The fabric prepared by waterproof fibers with a special porous structure is used in the embodiment of the present application. For details, refer to the microporous waterproof fiber dyeing and finishing fabric described in the patent document 202210750293.X; the fiber surface has a special groove structure, and after waterproof finishing, the capillary effect is used to form a water-repellent cavity underwater, so that a certain amount of air is locked inside the fiber, thereby increasing the buoyancy of the fabric.

[0043] The stretch fabric described in the embodiment of the present application is a woven blended dyed fabric product with a plain weave and a gram weight of 90-110 g / m 2 There is no special restriction on the color pattern, such as black, gray, blue, red, etc., and there may also be printed patterns.
