DRAWING FRAME DEVICE, CORE-SHEATH COMPOUND SPUN YARN MANUFACTURING METHOD, CORE-SHEATH COMPOUND SPUN YARN, AND WOVEN OBJECT

摘要

When manufacturing a core-sheath compound spun yarn, a drawing frame device gathers and draws core-side slivers which are positioned on the core side and sheath-side slivers which are positioned on the sheath side. The drawing frame device comprises a condenser, further comprising: a gathering guide which is disposed upstream of a draft zone, and gathers the core-size slivers and the sheath-side slivers; and a wire-type guide which has a helical shape, is disposed downstream of the gathering guide, and heats the core-side slivers and the sheath-side slivers which the gathering guide has gathered.
