Bunchy yarn, its spinning method and special spinning frame

Abstract

The present invention discloses a kind of bunchy yarn and its spinning method and special spinning frame. The bunchy yarn includes connected nodes and sections, and the each of the nodes consists of twisted main yarn fiber and auxiliary yarn fiber. The special spinning frame has middle and later horn cotton collectors, and the front, middle and later rollers driven separately with the programmable controller controlled front, middle and later servo motors. The main yarn fiber is fed through the middle horn collector on front of the middle roller for single drafting; and the auxiliary yarn fiber is fed through the later horn collector on front of the later roller for twisting in the middle horn collector and double region drafting. The present invention makes it possible to produce bunchy yarn with less opening and different node and section colors.

Description

technical field [0001] The invention relates to a slub yarn, and also relates to a spinning method of the slub yarn and a spinning machine for spinning the slub yarn. Background technique [0002] In recent years, slub yarn has been widely used in the market because of its strong three-dimensional effect and good air permeability. A known slub yarn comprises a core and a cover with knots distributed therein. This kind of slub yarn is formed by wrapping wire around the core wire to form knots of the main body of the yarn, and the core wire and the covering wire are continuous on the main body of the yarn. Its disadvantages are: 1) the core wire and the covered wire are easy to scatter; 2) the knot and the knot bar cannot form different colors. Known spinning frames, such as the A513 type spinning frame, can only spin plain yarns, but cannot spin slub yarns, have a single variety, and cannot adapt to the individual needs of the current market.

Its disadvantages are: 1) the core wire and the covered wire are easy to scatter; 2) the knots and knots cannot form different colors

Known spinning frames, such as the A513 spinning frame, can only spin plain yarns, but cannot spin slub yarns. The variety is single and cannot meet the individual needs of the current market.
