Description

Spinning method and preparation device of bidirectional wrapped super wear-resistant composite yarn

Technical Field

The invention relates to a device and a method for preparing bidirectional wrapped super wear-resistant composite yarn, and belongs to the technical field of spinning.

Background

The structure of the textile yarn body directly determines various properties of the yarn, and further limits the specific application field and scope of the yarn. The traditional ring spinning yarn is basically spun yarn formed by drafting, thinning, twisting and winding short fiber strands. The internal structure of the yarn formed by different yarn forming modes is greatly different, for example, in a ring spinning system, the internal and external transfer of the fiber is sufficient, and the fiber is mostly in a spiral arrangement track in a yarn body; in a compact spinning system, because a yarn-forming triangular area is narrowed, the internal and external transfer of fibers in a yarn body is insufficient; the siro spinning system has two spinning triangular zones, two strands of fiber strands respectively obtaining twist are twisted and then meet each other to be twisted into yarn again, and the yarn has obvious plied yarn style. However, the yarn is formed by short fibers according to different arrangement tracks, and the fibers exposed on the outer surface are easily drawn out during the rubbing process, which can cause the yarn structure to be disintegrated seriously, so the abrasion resistance is relatively poor.

The continuous filament has good snagging resistance and wear resistance, and has good application potential in the aspect of preparing high-wear-resistance yarns. The subsequent filament yarn combining spinning technology is to feed filament yarn from the front roller nip to combine the filament yarn with the short fiber bundle in the spinning triangle area to form yarn. Particularly, the filament can be coated on the surface of the staple fiber yarn by adjusting the feeding position of the filament, so that the hairiness on the surface of the staple fiber yarn is reduced, and the filament can be used as a wear-resistant support body. However, the stability of the covering effect of the single filament on the yarn body is relatively poor, and the phenomenon of white exposure can occur. Later, in order to improve the covering effect, two filaments are respectively arranged at two sides of a spinning triangular area, the covering effect is improved, but the filament covering method is used for passively covering by means of twist transmission, so that the filament covering direction is the same as the twisting direction of the yarn and is easy to slide, the yarn cannot form an effective locking structure, and the wear resistance is still poor.

Disclosure of Invention

Aiming at the technical problem that the wrapping direction of the filament in the filament/short fiber composite yarn body produced by the existing ring spinning technology cannot be opposite to that of the yarn, so that the structural stability and the wear resistance of the yarn are poor, the invention provides a spinning method of bidirectional wrapping type super wear-resistant composite yarn and a preparation device thereof, so as to solve the technical bottleneck, and the technical solution is as follows:

the invention discloses a spinning method of bidirectional wrapped super wear-resistant composite yarn and a preparation device thereof, which comprises an active filament winding unit and a ring spinning frame, wherein the active filament winding unit is arranged in front of the vertex of a spinning triangular area of a front roller jaw of the spinning frame, the active filament winding unit is formed by connecting two filament winding mechanisms and a bidirectional motor, the middle of the active filament winding unit is of a cylindrical hollow structure and coaxial with passing short fiber yarns, the filament winding mechanisms and the inner wall are respectively provided with a fiber conveying channel and a micro-tension regulator, and the bidirectional motor controls the filament winding mechanisms and the reverse rotation.

During spinning, roving sequentially passes through a rear drafting zone, a middle drafting zone and a front drafting zone and is output from a jaw of the front drafting zone to form a spinning triangular zone, filaments on the filament winding mechanism and the filament winding mechanism are unwound through respective fiber conveying channels and a micro-tension regulator respectively, the tension and the wrapping angle are regulated through the micro-tension regulator, the filaments are sequentially wrapped on the surface of the staple fiber yarn at a fixed inclination angle, the rotation direction of the filament winding mechanism is opposite to the twisting direction of the staple fiber yarn, the rotation direction of the filament winding mechanism is the same as the twisting direction of the staple fiber yarn, the filament winding mechanism and the staple fiber yarn are matched to form an obliquely-crossed wrapping structure, and the gathered filament/staple fiber composite yarn is wound on a spun yarn tube through a yarn guide hook.
