A method for producing bulky spun yarn, bulky yarn, fabric including a bulky spun yarn, and bulky spun yarn manufacturing equipment

摘要

While maintaining the tensile strength of the spun yarn, high yield strength for ironing on yarn surface, and, the manufacturing method for manufacturing a bulky yarn with a bulkiness, and the bulky yarn, the bulky spun yarn a fabric formed from, and is to provide an apparatus for producing the bulky yarn. Method for producing a bulky spun yarn, while it was drafted staple fiber bundle by using a roller pair for a plurality of succinimide to form a drafted fiber bundle, the downstream side of the rollers for multiple succinimide by guiding the rollers on the core yarn and drafting the fiber bundle at the same time, succinimide of forming a bulky fiber bundle by passing the downstream pair of rollers at a higher linear velocity than the linear velocity of the core yarn drafted fiber bundle I comprises a step, and a process of twisting the bulky fiber bundle and core yarn.
