Class 19/.56 - Combined


Subclass of Class 19 - Textiles: fiber preparation
Definition: Processes and apparatus constituting combinations of staplizing
No. of patents: 12
Last issue date: 09/20/1988


NumberTitleIssue Date
4771596Method of making fiber composite
A fine heterogeneous hybrid spun yarn is blended from electrostatically conductive staple fibers and electrostatically non-conductive staple fibers so that the yarn is electrostatically conductive only over short discrete lengths. When used in pile fabric...

4569811Method of making a staple-fiber band
A staple-fiber band is made by first spinning synthetic-resin filaments with spinnerets and drawing the filaments as roving at a predetermined feed speed from the spinnerets. The roving is then cooled without greatly stretching it so it has relatively hig...
