Title:
SLEEPING BAG HAVING IMPROVED THERMOKEEPING PROPERTY
Document Type and Number:
WIPO Patent Application WO/2020/184957
Kind Code:
A1
Abstract:
The present invention provides a sleeping bag provided with a thermokeeping improvement part comprising: a first insulation layer positioned on one inner direction surface of a covering of the sleeping bag and blocking inflow of external cold air; a first compressed fiber layer positioned on one surface of the first insulation layer; and a thermokeeping layer positioned on one surface of the first compressed fiber layer. According to the present invention: through the first insulation layer, external cold air can be blocked, and a leakage of internal warm air can be prevented, so that thermokeeping performance can be maximized; through the thermokeeping layer, heat is generated on the basis of each of vapor outside the sleeping bag and vapor inside the sleeping bag, so that a temperature inside the sleeping bag can be easily increased and maintained even without a separate heat source; and through the first compressed fiber layer, an inward convection current of cold air outside the sleeping bag is hindered, so that thermokeeping efficiency can be remarkably enhanced.
