摘要 |
A fabric of a polymer material useful for filtration and other purposes can be treated with a mixture of a solvent for the polymer material in a liquid which is not a solvent for the polymer material and which is more volatile than the solvent for a time and at a temperature sufficient to dissolve some polymer material in the strands. As this occurs the surface tension of the dissolved polymer will cause the dissolved polymer to move to create a continuous, smooth walled, curved surface connecting adjacent strands and extending between such strands.
