摘要： An object of the present invention is to provide a chenille yarn having a superior bulkiness suitable as a stuffing material for clothing and bedding, and a textile product including this yarn. This object can be achieved by a chenille yarn including a twisted yarn formed of a core yarn and a pressing yarn, in which a decorative yarn is fused and fixed between the core yarn and the pressing yarn, and the decorative yarn has a crimp having a radius of curvature of 0.5 mm or more to 5.0 mm or less.

摘要： An object of the present invention is to provide a bulky yarn made of synthetic fibers, which is suppressed in tanglement between filaments while having a loop shape in the surface layer thereof, and has a soft texture and is light and excellent in heat retention properties while being good in handleability in high-order processing. The present invention provides a bulky yarn made of synthetic fibers, including: a sheath yarn (1) having a three-dimensional crimped structure; and a core yarn (2) twisted with the sheath yarn (1) to fix the sheath yarn (1), wherein the sheath yarn (1) is not substantially broken and continuously forms loops.

摘要： 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.
