Abstract:
The present invention is a bulky yarn having: a sheath yarn (1) that has continuously formed loops without any breakages; and a core yarn (2) that substantially fixes the sheath yarn (1) by being interlaced with the sheath yarn (1). In the bulky yarn, the number of loops protruding from the yarn surface layer by not less than 3.0 mm is in a range of 1-30 loops/mm, the elastic modulus is not greater than 80 cN/dtex, and the extension recovery rate at the time of 10% extension recovery is not less than 50%. The present invention thus provides a bulky yarn having excellent touch feeling, excellent lightweight and heat retaining properties, and stretchability.
