Technical Field

The invention relates to a spinning method, in particular to a spinning method of long-segment section color yarns in air spinning.

Background

The rotor spinning is mature in the yarn market, has the advantages of high speed, large yarn roll, wide adaptability, simple mechanism, no need of spindles, rings, steel wire rings and the like, and greatly improves the yield of spun yarns. However, the current open-end spinning varieties are coarse count yarns and low-grade yarns, and are used for jeans and other varieties, and the price of the open-end spinning yarns is much lower than that of other spinning types such as vortex spinning, ring spinning and the like due to the spinning type and the spinning count. The main reasons are that the air spinning lacks innovation in many aspects such as fabric style, the design is stiff, the style is old and the like, and the low value-added air spinning product seriously restricts the development of the air spinning in a novel spinning technology and a novel fabric.

Disclosure of Invention

The invention aims to overcome the defects of the prior art and provides a spinning method of long-segment sectional color yarns in air spinning.

The invention relates to a spinning method of medium-length segment colored yarn in air spinning, which comprises the following steps:

step 1: preparing air-spun short fiber slivers;

step 2: preparing common slivers;

and step 3: the air spinning short fiber slivers and common slivers are mixed to be made into final drawing, and air spinning sectional color yarns are spun.

In the method for spinning the long-piece segment-color yarns in the air spinning, the strips of the air-spun segment-color yarns are any fibers with different lengths.

In the method for spinning the long-segment colored yarn in the air spinning, the method for mixing the fibers with the selected length and the common fibers is a drawing and mixing process.

In the spinning method of the long-piece segment-color yarn in the air spinning, the length of the selected raw material for spinning the segment-color yarn in the air spinning is about 10mm-25 mm.

In the spinning method of the long-piece segment-color yarn in the air spinning, the raw material of the selected air spinning segment-color yarn is any textile fiber raw material used in spinning.

In the method for spinning the middle-long segment-colored yarns in the air spinning, the air spinning segment-colored end drawing is grabbed and carded by a carding roller, the grabbed and carded fibers are different in length, the fibers with different lengths are different in carding degree under different actions of centrifugal force of a rotor, and the fibers firstly enter an air cup to form large cheese by feeding the fibers and kneading the yarns, namely the novel style of the middle-long segment-colored yarns in the air spinning.
