Detailed Description

The present invention will be further described with reference to the accompanying drawings and specific embodiments.

Example one

The present embodiment will be described in detail with reference to fig. 1 and 2. The compound non-woven fabrics of cool sense of hydroscopicity that this embodiment relates includes cool sense top layer 1, polylactic acid fibrous layer 2 and the viscose fiber layer 3 of hydroentangling reinforcement, one side that the polylactic acid fibrous layer 2 was kept away from to viscose fiber layer 3 is provided with prevention of seepage membrane 4.

The cool surface layer 1 is a pearl pattern bulge formed by cool fibers; the cool fiber comprises a core layer fiber 11 and a cool mineral layer 12 arranged on the outer surface of the core layer fiber 11; the cross section of the polylactic acid fiber used in the polylactic acid fiber layer is in a cross shape or a Y shape.
