Abstract

The invention provides breathable and moisture permeable biodegradable thermal insulating flakes and a preparation method thereof. The thermal insulating flakes use Viloft fiber as the floc main bodyand three-dimensional crimped hollow fiber and far-infrared fiber as skeleton; ES fiber is made of hot adhesive by hot melt bonding. The present invention is a method of processing a thermal insulating flake using a nonwoven technique. The method uses a variety of different types and functions of new fibers, so that the flakes aggregate the good moisture absorption and desorption of viloft fibers,the curling properties of three-dimensional crimped hollow fibers and the health care function of far-infrared fibers. The invention has certain environmental protection property, and most of the products are biodegradable under certain conditions after the product is discarded.

Description

technical field [0001] The invention relates to the field of non-woven fabrics, in particular to a breathable and moisture-permeable biodegradable warm-keeping flake and a preparation method thereof. Background technique [0002] Most of the thermal insulation flakes are made of synthetic fibers, cotton fibers, silk fibers, down, etc., because the modified synthetic fibers have good heat retention and low price, so they are widely used in thermal insulation flakes. [0003] Synthetic fibers have poor hygroscopicity. When they are used as flocs, they cannot absorb the sweat on the surface of the human body in time. stuffiness. In addition, synthetic fibers have poor moisture release properties. After absorbing moisture in the air or human sweat, they cannot be discharged in time and remain between the fibers, making the flakes feel damp, and greatly reducing warmth retention and comfort. [0004] Synthetic fibers are mostly composed of high polymers, which are difficult to ...
