Embodiment 1

[0037] The core-spun composite yarn is spun by using polyester spun rovings with a basis weight of 300tex and polyester filaments with a basis weight of 125dtex. The core-spun yarn of 21tex is spun on the JWFA1520 type spinning frame. The specific process parameters are as follows: roving basis weight 300tex; spun yarn basis weight 21tex; spindle speed 8000r / min; draft ratio 14.3; top roller 3 speed 14.3m / min; The polyester filament 8 passes through the arc surface of the protection block 5, and is sent into the accumulation groove 7 on the triangular stable block 6 along the surface of the counterweight plate, and the staple fiber roving 9 fed into the jaw line passes through the same accumulation process as the filament 8. Slot 7. The two-dimensional two-way bell mouth in the collecting groove 7 plays a whole bundle effect on the roving strands, and the polyester filament 8 passes through the top narrow opening of the same collecting groove 9, effectively positioning the po...

Embodiment 2

[0040] Siro-spun composite yarns were spun by using cotton staple rovings with a basis weight of 5.20g / 10m and polyester filaments with a basis weight of 2.44tex / 12f. The filament 8 is precisely positioned, and the feeding position of the filament 8 is adjusted by selecting the gathering groove 9 where the filament 8 penetrates and the gathering groove 9 where the cotton roving 8 penetrates, and the winding structure of the Siro spinning is adjusted. The specific spinning process is: spun weight 55.8tex; draft ratio 10.7; spindle speed 8000r / min; top roller 3 speed 14.3m / min; twist coefficient 380. The polyester filament 8 passes through the arc surface of the protection block 5, and is sent into the accumulation groove 7 on the triangular stability block 6 along the surface of the counterweight block, and at the same time, the staple fiber roving 9 fed into the jaw line passes through and accumulates with the filament 8. The grooves 7 are separated by 7 mm from the collecting...

Embodiment 3

[0043] The positioning and accumulating device for the filament 8 and the spun roving 9 will also be applicable to various composite spinning methods such as sirofil spinning and embedded composite spinning.

Abstract

The invention provides a short-fiber rove and filament positioning collector for composite yarn spinning. The positioning collector is arranged between a front roller and a top roller of a spinning frame and comprises a first counterweight plate, a second counterweight plate, two protection blocks and two triangular stabilizing blocks; the first counterweight plate and the second counterweight plate are rectangular plates which are horizontally arranged side by side, the upper ends of the sides, away from each other, of the two counterweight plates are connected with the lower ends of the protection blocks which are correspondingly arranged at the upper portions respectively, and the lower ends of the sides, away from each other, of the two counterweight plates are connected with the upperends of the triangular stabilizing blocks which are correspondingly arranged at the lower portions respectively; the two triangular stabilizing blocks are provided with collecting grooves for filaments and cotton roves to pass through, and the first counterweight plate and the second counterweight plate move in the horizontal direction to get close to or away from each other, so that the two collecting grooves are driven to move to get close to or away from each other. The short-fiber rove and filament positioning collector for composite yarn spinning is wide in application, simple in operation, precise in regulation, high in work efficiency and capable of improving the product quality.

Description

technical field [0001] The invention belongs to the technical field of textile equipment, and in particular relates to a spun roving and filament positioning collector for composite yarn spinning and an application thereof. Background technique [0002] The composite spinning technology of filament and staple fiber roving can make the yarn have the style, feel, hygroscopicity of natural staple fiber and the crispness and shape retention provided by the strong elongation of filament itself. This excellent yarn quality and The unique yarn structure has attracted more and more attention in recent years, and has rapidly developed into an important method to meet the diversity of textile properties. At present, the spinning methods that can produce filament and staple roving composite yarn mainly include ring spinning, air-jet spinning, rotor spinning, hollow spindle spinning, etc. Among them, the most mature and widely used is the ring spinning composite spinning technology. ...
