Here, the chemical foam is a microcapsule excellent in elastic recovery after expansion by heat. The true density of the microcapsules before expansion is 1,250 to 1,300 kg / m 3, and after full expansion, the true density decreases to 20 kg / m 3 or less. This means that the volume increases more than 50 times. It is preferable that the initial diameter before expansion is 6-18 mu based on the volume average. The chemical foam is expanded at 130 ° C. by heat treatment, and expansion is completed in the final heat treatment step, and the volume expands from the initial diameter of 6 to 18 μ to 40 to 120 μ.

As the composition used for the surface heat absorbing layer 4, not only the solvent type described in the embodiment of the present invention but also the following emulsion type can be used.

100 parts by weight of one component or a mixture of two or more thereof selected from the group consisting of urethane resin emulsions, acrylic resin emulsions, and nitrile rubber emulsions having a solid content of 30 to 95% by weight, isocyanate type, melamine type, epoxy type, and ethylene 1-5 parts by weight of a crosslinking agent selected from the group consisting of imine-based crosslinking agents or a mixture of two or more thereof, 3-15 parts by weight of carbon black, and 5-30 parts by weight of zirconium carbide are coated on the thermal insulation foam layer It is applied to form a surface absorbing layer (4).

The heat-retaining heat-insulating material is a material that gives about 4 to 5 times more heat insulation than general materials due to absorption of solar heat and infrared heat insulation of body temperature. In general, 95% of the light is absorbed and converted into energy in the clothes to radiate into the far infrared. In this far-infrared region, energy is accumulated in the clothes due to high reflectance. In addition, the human body emits far infrared rays in the vicinity of 10㎛ when the near the object of the same wavelength is a resonance phenomenon occurs, then heat is generated and blood circulation in the human body is promoted. In particular, zirconium carbide (ZrC), which is widely used for heat storage, is known as an ideal material having high absorption power in the short wavelength region of infrared rays and visible rays, which occupy 95% of sunlight. Heat storage thermal insulation materials that can be used in clothing include aluminum, carbon, alumina-based materials, zirconium carbide and the like. Aluminum is easily oxidized in air, and carbon has a large endothermic effect but a poor thermal effect. Alumina-based materials emit most of light at wavelengths in the far infrared region, and thermal insulation is not excellent. Zirconium carbide has a very high light absorption rate, high far-infrared emissivity, and excellent heat absorption, heat storage and radiation performance. Taking advantage of this, the inventor included carbon black and zirconium carbide in the surface endothermic layer 4.

After applying the composition consisting of the adhesive layer (2) (optional), the thermal insulation foam layer (3), the surface heat absorbing layer (4) on the bubble paper (1) sequentially, the resultant is preliminary at 100 to 120 ℃ After drying, it is introduced into a dryer having a three-stage structure to minimize the air volume of all the dryers and gradually increase the air volume toward the middle and rear parts, and finally, heat treatment at 150 to 170 ° C., and then cool to apply the present invention.
