Problems solved by technology

The rotor spinning technology has a history of 75 years since it was invented in 1937, but my country only started to study and apply the rotor spinning technology in the late 1960s. Due to various reasons, the current rotor spinning technology is only applicable to the cotton spinning industry. Production of low-count yarns, which has not yet been applied to multi-fiber yarns

Embodiment Construction

[0019] The invention relates to a method for producing multi-fiber yarns by rotor spinning, which comprises the following process: loose fiber dyeing → wool blending process → carding process → drawing frame → rotor spinning process → yarn doubling process → two-for-one twisting process, In the rotor spinning process, the fiber sliver is transported to the opening roller through the feeding mechanism, and under the action of the card clothing on the opening roller, the fiber sliver is combed into a single-fiber-like fiber flow again, and the single-fiber flow is Under the action of centrifugal force and negative pressure air, the comb roller separates from the pin teeth of the opening roller and enters the spinning cup under the action of negative pressure air. The spinning cup is a high-speed rotating part. After the single fiber flow enters the spinning cup , enter the coagulation groove under the action of its centrifugal force, so that the single fiber gathers again and for...

Abstract

The invention relates to a diversified fiber yarn production method by rotor spinning, which includes the following process steps: the bulk fiber dyeing step, the wool mixing step, the combing step, the drawing step, the rotor spinning step, the doubling step and the twisting step. In the rotor spinning step, fiber strips are conveyed to a combing roll through a feeding mechanism and are combed into single fibrous fiber flow under the action of the combing roll, the single fiber flow is separated from the combing roll and enters a spinning rotor under the action of centrifugal force and negative pressure of the combing roll, and enters a U-shaped concentrating groove under the action of the centrifugal force after entering the spinning rotor, so that single fibers can be reconcentrated to be in the shape of rings and form yarns under the action of seed yarns and a twister. The diversified fiber yarn production method by rotor spinning is superior to the ring spinning method in yarn quality, production capacity, energy consumption, labor using and benefits and the like.

Description

technical field [0001] The invention relates to a method for producing multiple fiber yarns by rotor spinning. Background technique [0002] Diversified fiber yarn is a composite fiber yarn developed by my country's independent innovation in the past 10 years. Diversified fiber spinning technology is based on cotton spinning equipment and technology, and integrates some wool spinning equipment and technology. The fibers used in the yarn cover functional fibers such as cotton, wool, silk, hemp, chemical fiber, and modified and denatured fibers. The suitable fiber length for spinning is above 20mm and below 60mm, and the suitable fiber fineness for spinning is below 3.0Dtex. The multi-fiber yarn fabric combines the advantages of the fibers used, improves the wearability of the fabric, and improves the sensual appearance of the fabric. [0003] Ring spinning and rotor spinning are two spinning methods widely used at present. The production process of ring spinning multi-fiber...
