The existing hollow fiber thermal insulation material adopts a design scheme of a hollow through hole pipe with an ultrafine wire diameter, and does not adopt a technical scheme of sealing the whole hollow fiber pipe in a whole section or in a segmented manner, because the closed hollow pipe cavity is deformed and broken under pressure due to the use environment temperature difference change and external force extrusion factors, the water resistance and the moisture resistance of the hollow tubular thermal insulation material are reduced. Affecting the stability of heat preservation and heat insulation. The technical scheme of the material has complex manufacturing process and high cost.
