Title:
DOWN AND POLYMER MIXTURE THERMAL INSULATING SHEET
Document Type and Number:
WIPO Patent Application WO/2020/178799
Kind Code:
A3
Abstract:
A light weight composite thermally insulating sheet is comprised of down insulation mixed with binding fibers and plant-based material fibers. The plant-based material fibers maintain their original state during heat treatment to bind the core material together. As the binding fibers soften, they bind together at their crossing and also attach to the plant-based material fibers which remain in their original state creating an inner bonded support fiber structure made of plant-based material fibers and binding fibers. This fiber structure maintains the loft in the core by resisting to heat deformation of the binder material during the heat treatment to reduce compression of core material. The plant-based material fibers also act as wicking conductors to conduct moisture out of the down material and providing a faster drying of the thermally insulating sheet. Carbon fibers may be added to the core mixture of the scrim sheets, if used, may be formed of charcoal yarn to absorb odors.
