On the other side of the air pad 30, the upper nonwoven fabric supply step (D) of winding and supplying the upper nonwoven fabric 40 of 50 g to 60 g weight% of polypropylene SS component per 1 m2 to the winding roller is performed on the lower nonwoven fabric 10 , The insulating nonwoven fabric 20, the air pad 30, and the upper nonwoven fabric 40 operate in the same direction,

The lower non-woven fabric 10, the heat-insulating non-woven fabric 20, the air pad 30, and the upper non-woven fabric 40 are simultaneously pulled in and moved in the longitudinal direction while being overlapped in a multi-layered state, making the stitching 50 uniform, and such a stitching Through step (E), it is manufactured as one multi-layered finished thermal cover (1) and discharged.

As shown in FIG. 6, in the step (B) of supplying the insulating nonwoven fabric,

It can be selectively sprayed on the upper or lower surface of the insulating nonwoven fabric 20 through the airgel spraying step (B-1) in which the airgel 210 is sprayed so as to maintain the porous form of nanoparticles, providing breathability for various purposes. It works to adjust the insulation and warmth,

The heat-insulating nonwoven fabric 20 discharged through the airgel spraying step (B-1) is passed through the chamber space (B-2) where the temperature is maintained at 100 to 150 ° C. to promote curing, and the curing space (B It is cured in -3) to prevent it from escaping to the outside from the surface of the heat-insulating nonwoven fabric (20).
