ABSTRACT:
A method of manufacturing polychromatic artificial yarns incorporating liquid crystals is provided.
According to this method, a transparent film sheet of plastic or other suitable material having a row of a plurality of longitudinally extending grooves on its outer surface is prepared and then coatings of micro-encapsulated liquid crystals, and particles of an ultra-violet light adsorbent are applied onto the grooves. After these processes, the entire outer surface of the film sheet is coated with a thin layer of carbon black and is then covered adhesively with another transparent film sheet of the same material. The entire material is finally cut out, across the second and first mentioned film sheets, longitudinally along the grooves to produce linear strips to be spun into yarns.
