The utility model discloses a kind of ventilated porous composite sponge pad, it is related to sponge pad technical field, including pad body and the heat dissipation cavity being set on it, pad body top and bottom two ends are respectively adhered and fixed with solid surface layer, pad body top is communicated with pad body periphery by heat dissipation cavity;It also includes the bamboo charcoal fiber filling layer in heat dissipation cavity;Solid surface layer is breathable, and solid surface layer is ice silk fiber layer;The utility model has the advantages that: after bamboo charcoal fiber filling layer is inserted into heat dissipation cavity, certain support can be provided to increase the stability of heat dissipation cavity when being pressed, to strengthen the ventilation and heat dissipation property;Bamboo charcoal fiber filling layer can also provide moisture absorption and perspiration function and itself has certain thermal conductivity, can promote the diffusion and emission of heat;Solid surface layer is as surface layer and uses ice silk fiber layer or flax fiber layer, can provide thermal conductivity to transfer heat to bamboo charcoal fiber filling layer, and itself has good moisture absorption and perspiration performance, can improve the cool feeling.

The invention belongs to the technical field of textile, and relates to a preparation method of a polyester fabric with moisture absorption and sweat releasing functions, which comprises the following steps: reacting waste leather scraps with phosphoric acid to prepare a regenerated collagen modifier; coating slurry is prepared, polyester fabric is soaked in the coating slurry and then subjected to two-stage standing treatment, and the polyester fabric with the moisture absorption and sweat releasing functions is obtained; the coating slurry contains a regenerated collagen modifier, an anionic waterborne polyurethane dispersion, a polyisocyanate curing agent and a cross-linking agent. The method is simple, and the moisture absorption and sweat releasing functions of the polyester fabric are improved.
