Description

Drafting mechanism for feeding three thick yarns and spinning device

Technical Field

The utility model belongs to the technical field of the spinning, concretely relates to spun yarn technology and spun yarn device of three roving feeding.

Background

Spun yarn is a relatively thin yarn re-spun from roving and used for weaving or spinning. The spinning process is to spin the roving into spun yarn with certain number of figures and meeting the national quality standard for twisting, weaving or knitting and the like, and the spun yarn process mainly completes the following tasks: (1) drafting: uniformly drawing and thinning the fed roving or sliver to the special number required by the spun yarn; (2) twisting: the drafted fiber strands are added with proper twist, so that the finished yarn has certain physical and mechanical properties such as strength, elasticity, luster, hand feeling and the like. (3) Winding and forming: the spun fine yarn is wound on a bobbin according to certain forming requirements so as to be convenient for transportation, storage and subsequent processing. Spun yarn is an important process for spinning and is also the last process in spinning production.

Siro spinning is a spun yarn process realized on a traditional spinning frame, and is a double-yarn spinning twisting method, namely two pieces of roving are respectively drafted into fiber strips and then twisted into yarn. The sirospun yarn has the characteristics of less hairiness, smooth appearance, good wear resistance and soft hand feeling.
