Abstract
The invention relates to a method for forming dual-component heat-insulating wadding by combining molten-spraying nonwoven fabrics and down. Specifically, the method comprises the following steps: heating polymer resin slices into molten state, then extruding, measuring and distributing the resin slices evenly to a hole of a spinneret device, and then stretching the resin slices into superfine fiber by hot air. Then the down is adhered with polymer fiber which is treated with fiber-stretching and is still not cured so as to form a net after being distributed by loosening, velvet-supplying and velvet-filling , and then a receiver and a finishing reel wind the net into the wadding. The invention adds down material into the existing molten-spraying production process, which can improve the heat-insulating rate and rebound elasticity of the wadding and can improve the transverse and longitudinal tensile strength of the wadding.
