Abstract
The process of reducing dust particles formed in the fibrillation of tape yarns of synthetic material by applying a sufficient amount of heat to the fibrillated tape yarn to cause said synthetic dust particles to fuse into said tape yarn.
Claims10
A process for reducing dust particles in a fibrillated tape yarn of synthetic material in which said dust particles are formed in the fibrillation of said tape yarn, comprising the steps of:
- a. relatively moving fibrillated tape yarn of synthetic material past a heating station,
- b. applying a critical amount of heat to said tape yarn at said heating station sufficient to fuse only said dust particles into said tape yarn,
- c. said critical amount of heat being sufficient to melt said dust particles but insufficient to melt or damage said tape yarn.
