Abstract

The invention discloses a molding method of liquid cooling polymer monofilament. The method includes that polymer melt ejected by a spinneret plate component enters a liquid box to perform liquid cooling molding and is delivered out of the liquid box through front and back winding rollers in the liquid box to enter a sequence process; the front and back winding rollers are on a same horizontal plane, and the distance between the front and back winding rollers is in a range of 50cm to 200cm, wherein liquid temperature in the liquid box is in a range of 5 DEG C to 95 DEG C, the distance between a spinneret end of the spinneret plate component and the liquid level of liquid box is in a range of 1cm to 10cm, and the distance between the roller in the liquid box and the liquid level is in a range of 10cm to 150cm; the liquid in the liquid box is a circulation liquid with a flow rate of 25-150kg / h, and the liquid in the liquid box is a mixture of water, triethylene glycol liquid or paraffin liquid. The molding method has the advantages that the process is simple, the operation is convenient, and molded fibers have high strength, roundness and uniformity, and the like; and the method is particularly suitable for being used by paper making molding nets, filter fabrics, special screens and the like.

Description

technical field [0001] The invention relates to a polymer monofilament forming method. Background technique [0002] The conventional cooling molding method of polymer monofilament is mainly in the form of wind blowing cooling, etc., and the strength, roundness and uniformity of the fiber have defects, which affect the working performance. Contents of the invention [0003] The object of the present invention is to provide a polymer monofilament forming method with reasonable structure and good fiber performance.
