PURPOSE:To obtain the subject yarn giving a stain-resistant carpet having excellent stain-proofing property without using a water-washing process, etc., by melt-spinning a fiber-forming polymer containing a mass-coloring pigment or mass-coloring dye, applying a lubricant to the fiber and removing the lubri cant using a specific means. CONSTITUTION:A lubricant is applied to a yarn produced by the melt-spinning of a polymer forming a thermoplastic synthetic fiber and containing mass- coloring pigment and/or mass-coloring dye. The yarn is subjected to hot-drawing and/or drawing and crimping treatment and/or water is applied to the yarn after the hot-drawing and/or crimping treatment to remove the lubricant from the yarn. The objective yarn having <=0.3wt.% of oil component of the lubricant attached to the fiber surface is produced by this process. The lubricant is prefer ably the one containing a hydrophilic surfactant and an oleophilic smoothing agent. |
