Title: Production of pile yarn for carpet
Inventor: MISAKI AYUMI
IPC: D06P5/00
Filed: 1992-11-26
Abstract: PURPOSE:To provide a method for producing pile yarns capable of easily obtaining multicolor-patterned cut-and-loop carpets. CONSTITUTION:Dyed or undyed pile raw yarns are imparted with a water repellent and heat-treated in order to firmly stick this water repellent to the yarns, and the resultant yarns are then dyed by an established means. Thereby, since the dyeing liquid does not penetrate into the center of the pile raw yarns, the objective pile yarns having sheath-core structure in terms of colors which are mutually different at the center and the periphery can be obtained. Using this pile yarns, cut-and-loop carpets whose colors at the cut portions and loop portions are different from each other can be obtained. Otherwise, after the heat treatment, the yarns are imparted with a dyeability-variable chemical agent to another version of pile yarns having a mutually different dyeability at the center and the periphery can be obtained. Using these pile yarns, multicolor-patterned cut-and-loop carpets can also be obtained.
