PROBLEM TO BE SOLVED: To solve new problems that the transparency of a spun fiber is not at a satisfactory level in order to obtain the fiber of a clear tone and the extrusion rate cannot be increased by the amount suppressed of a lubricant used though a hydrotalcitic heat stabilizer is used in the vinyl chloride fiber. SOLUTION: A system of 100 pts.wt. of a vinyl chloride resin, 0.1-2.0 pts.wt. of the hydrotalcitic heat stabilizer and 0.2-2.0 pts.wt. of a lubricant is compounded with 0.5-5 pts.wt. total of one or more kinds of acrylic polymer having≥0.08 to <0.5 specific viscosity in the fiber obtained by carrying out melt extrusion spinning of a vinyl chloride resin composition. Thereby, gelation of the vinyl chloride resin composition is promoted and moderate lubricity and viscosity are imparted. The dispersibility is improved to reduce resinous deposits around a resin outlet and the spinnability is stabilized. The extrusion efficiency of an extruder can be improved to increase the extrusion rate. COPYRIGHT: (C)2006,JPO&NCIPI
