摘要： A process and apparatus is disclosed for preparing Moresque (multicolored) yarn from thermoplastic polymers. An elongated flat die is utilized to extrude parallel streams of molten polymers of alternating colors onto a casting roll to form a thermoplastic polymer film. Desired color combinations can be obtained by preselecting the colors of the molten polymer streams. The congealed film is oriented in the longitudinal direction to increase the longitudinal strength. The stretched film is cut in strips of uniform width by means of a cutting tool with a series of cutting heads. In order to obtain a random color distribution on the edges of individual strips, the film is oscillated across the direction of the longitudinal axis prior to cutting. These strips are fibrillated to produce a fibrous network which upon twisting simulates natural yarns suitable for indoor-outdoor carpets or general commercial textile use.
