PROBLEM TO BE SOLVED: To provide a lightweight and sufficiently bulky and strong bulky yarn which has soft texture and excellent heat insulation property.SOLUTION: The bulky single yarn 8 satisfies the following characteristic values (1) to (3): (1) the bulkiness is 13.5 to 25.0 cm/g, (2) the elongation is 7.98 to 36.0%/N per unit strength, (3) and the value obtained by dividing the maximum strength on a tensile fracture by the value of the bulkiness is 0.048 to 0.140 N/(cm/g). |
