As can be seen from table 4: the surface density of the modified PET/PA6 double-component spun-bonded spunlace non-woven layer and the hot rolling temperature in the preparation process have certain influence on the heat-insulating property of the heat-insulating material.
The thermal performance of the thermal material can reach 0.42012, the thermal performance of the thermal material in example 1 can reach 0.41392, and compared with the thermal performance of the outdoor material (polartec Crow value is 0.16-0.28) and the thermal underwear (thermal underwear Crow value is about 0.13), the Crow value shows that the thermal material has better thermal performance.
Combining the data in the table 4, if the areal density of the modified PET/PA6 bicomponent spun-bonded spunlace non-woven layer is changed, the Crohn value of the thermal insulation property is reduced to 0.36913; if the hot rolling temperature changes in the preparation process, the thermal performance Crot value is reduced to 0.33033, so that the thermal performance of the material can be completely influenced by the change of the hot rolling temperature.

As can be seen from table 5: the surface density of the modified PET/PA6 double-component spun-bonded spunlace non-woven layer and the hot rolling temperature in the preparation process have certain influence on the hydrostatic pressure resistance of the thermal insulation material.
The hydrostatic pressure of the warm-keeping material is 5330Pa, the warm-keeping material has excellent waterproof performance, and if the surface density of the PET/PA6 double-component spun-bonded spunlace non-woven layer changes, the hydrostatic pressure is reduced to 1214 Pa, so that the waterproof performance is obviously influenced.
The hot rolling temperature also has a certain influence on the hydrostatic pressure, and if the hot rolling temperature is too low, the hydrostatic pressure tends to decrease.
