Method for precursor fiber curing molding during ultrahigh-molecular-weight polyethylene dry spinning

The invention relates to a method for precursor fiber curing molding during ultrahigh-molecular-weight polyethylene dry spinning. The method is characterized in that ultrahigh-molecular-weight polyethylene spinning solution is extruded through a spinning nozzle and then enters a processional road for curing molding in a tow form, the processional road comprises an evenly heating area and a circulating blowing area which are arranged with one above the other, and the tow passes through the evenly heating area and the circulating blowing area in sequence to form precursor fiber with certain crystallization orientation degree. Compared with the prior art, the method has the advantages that organic solvents in the precursor fiber can be effectively removed, the crystallization orientation degree of the precursor fiber can be increased, and fiber strength can be improved. The tow passes through the processional road to form the precursor fiber with certain crystallization orientation degree, and the precursor fiber has certain strength, can be subjected to ultra-hot-drawing and is especially suitable for the field of ultrahigh-molecular-weight polyethylene fiber dry spinning.
