▎ 摘  要

NOVELTY - Preparing heat-conducting non-woven fabric material involves cutting the polyester slice, drying the color masterbatch for future use. The polyester slice and color masterbatch after drying are put into the screw extruder, then the polyester slice is extruded and filtered for future use. The polyester slice melt is poured after filtering into the spinning box body, and quantitatively conveyed by a metering pump. The melt is cooled from the metering pump to wire, and stretched by air flow traction, after the drawn yarn is scattered by the swinging machine, then absorbed to the transmission net curtain, and compacted by the pre-pressing roller. The net wire after compacting through the first needle machine is repeatedly puncturing for primary connection, and then performing reverse repeated puncture by the second needle machine for strong locking, obtaining non-woven fabric. USE - Method for preparing heat-conducting non-woven fabric material for electric blanket used for improving temperature of quilt in quilt when people sleep and for dehumidifying bedclothes. ADVANTAGE - The method is carried out in a simple, convenient, and cost-effective manner, and the prepared non-woven fabric material has good heat conducting performance, and it is not easy to drop hair. The method improves the heating efficiency and effect of the electric blanket, because the needle-punched nonwoven cloth is made of long fiber, and before soaking for blanching, distinguishing the surface of hair, which effectively solves the problem that the short fiber needling non woven fabric has serious hair loss. DETAILED DESCRIPTION - Preparing heat-conducting non-woven fabric material involves cutting the polyester slice, drying the color masterbatch for future use. The polyester slice and color masterbatch after drying are put into the screw extruder, then the polyester slice is extruded and filtered for future use. The polyester slice melt is poured after filtering into the spinning box body, and quantitatively conveyed by a metering pump. The melt is cooled from the metering pump to wire, and stretched by air flow traction, after the drawn yarn is scattered by the swinging machine, then absorbed to the transmission net curtain, and compacted by the pre-pressing roller. The net wire after compacting through the first needle machine is repeatedly puncturing for primary connection, and then performing reverse repeated puncture by the second needle machine for strong locking, obtaining non-woven fabric. The non-woven fabric is subjected to hot ironing, removing the surface burr, placing the non-woven fabric in the graphene dipping glue solution for soaking. The redundant liquid is extruded in the soaked non-woven fabric, and dried to obtain finished product.
