Problems solved by technology

Since the position of the roving sliver in the drafting zone is not adjusted and controlled, the position of the roving sliver may be shifted, and it is difficult to ensure that the position distance in the drafting zone remains constant. There are certain difficulties. Uneven tension is prone to occur in spinning production, resulting in changes in the yarn structure. Therefore, it is also difficult to spin composite yarns with a skin-core structure in this way in actual spinning production.

Abstract

The invention provides a processing method and a device for full-short-fiber composite structure yarns. The processing device comprises a roving feeding coordination device (8), a roving coordination adjusting device (9), a roving coordination maintaining device (10), and a twisting device. The roving feeding coordination device (8) is provided with a first hole (19) for a second short fiber roving fiber strand (2) to pass through, and a second hole (20) for a first short fiber roving fiber strand (1) to pass through. The first hole and the second hole are arranged in an up and down manner. The roving coordination adjusting device (9) is used to adjust left and right relative positions of the first short fiber roving fiber strand and the second short fiber roving fiber strand. The upper surface of the roving coordination maintaining device (10) is provided with a semi-circular groove (33) for the second short fiber roving fiber strand to pass through, and the lower surface is provided with a round concave arc arch groove (34) for the first short fiber roving fiber strand to pass through. The twisting device is used to wind the first short fiber roving fiber strand on the second short fiber roving fiber strand. The processing method and the device for full-short-fiber composite structure yarns are clever in structure and good in practicality.

Description

technical field [0001] The invention relates to the technical field of ring spinning, in particular to a processing method and equipment for all-short fiber composite structure yarn. Background technique [0002] In recent years, with the continuous development of spinning technology, the continuous improvement of textile equipment and the increasing market requirements for the use of various new textile fabrics, the research and development of new structural yarns has become a key direction of the textile industry. , which includes the research and development of multi-component yarns. By spinning different fibers into the same yarn, multi-component yarns can realize the complementary advantages of different fiber properties and greatly improve the performance of yarns. At present, there are two main types of multicomponent yarns: blended yarns and composite yarns. [0003] Blended yarn is to mix two or more fibers according to a certain ratio in the previous process of s...
