PRE-TREATMENT SOLUTION OF DYEING FOR ULTRA HIGH MOLECULAR WEIGHT POLYETHYLENE YARN

摘要

PURPOSE: A method for preprocessing of ultra high molecular weight polyethylene yarn for dyeing is provided to dye the ultra high molecular weight polyethylene yarn with a general dyeing chemical through a simple physical process. CONSTITUTION: A method for preprocessing of ultra high molecular weight polyethylene yarn for dyeing includes the following steps: applying a lubrication solution on the ultra high molecular weight polyethylene yarn; preparing a cylindrical blowing pipe(10) connected to an air supply pipe(20); and striking the ultra high molecular weight polyethylene yarn while passing the ultra high molecular weight polyethylene yarn through the blowing pipe. A pair of front rollers(50) are installed at the front of the blowing pipe. A pair of back rollers(40) are installed at the rear of the blowing pipe.
