Abstract
The production process of microfibrous materials or fibrils in which polyolefinic polymers are spun through an orifice under high temperature and high pressure is called flash spinning. A study was made to determine the high strength fibril producing conditions by dry-spinning a solution of polypropylene in dichloromethane through an orifice at high temperature and high pressure. The water system used in conventional paper forming processes is not applicable in forming a sheet of polyolefine fibrils. In order to develop a solvent system for a sheet forming process capable of dealing with hydrophobic fibrils, a comparative study of various solvents was made to determine how the solvent might facilitate the sheetforming operation. Solvents having solubility parameters near those of polyporpylene promoted the formation of paper-like sheets of fibrils with satisfactory physical properties. We developed new technology for a solvent forming system by modifying a conventional water system so that polypropylene fibrils could be introduced as synthetic pulp.
