Yarn with partial dyed side surface and device for adhering dye liquid to drying and taking up the same

Abstract

The invention provides a partial dyed yarn having a partial dyeing applied to a side surface of fibrous raw material and further provides a method for manufacturing thereof. A partial dyed yarn is provided by a dye liquid adhering method and a dye liquid adhering, drying and taking-up device which is capable of accomplishing a high quality dye printing yarn. A continuous fibrous raw material is passed through the dye liquid adhering roll, the dye liquid is partially or continuously adhered to the thread-like side surface of the fibrous raw material, and thereafter it is applied with a heat treatment to cause the yarn to be dyed in a desired color tone efficiently and quickly. The fibrous raw material is passed over a guiding groove formed at an outer circumference of the dye liquid adhering roll at a desired yarn speed while a tension force is being applied to it, the dye liquid adhering roll is properly rotated with its frictional force and at the same time, its amount of adhesion is controlled and the yarn is passed in a hot air drying device while it is turned therein so as to dry the adhered dye liquid. The yarn is then taken up as a dried cone and it is processed with heat treatment to obtain a yarn partially dyed on the side surface thereof.
