Embodiment 1

[0023] A variable twist yarn, including a strong twist yarn section and a weak twist yarn section. The yarn composition of the variable twist yarn is short fiber pure spinning or multi-component blending. The yarn thickness of the variable twist yarn remains unchanged, and the twist of the yarn along the yarn The axis of the line changes;

[0024] The twist ratio of the strong twisted yarn segment to the weak twisted yarn segment is 1.2-1.8, and the length of the strong twisted yarn segment to the weak twisted yarn segment is 1m-20m;

[0025] The ratio of the twist size of the strong twist yarn segment to the weak twist yarn segment is 1.5;

[0026] The length of the strongly twisted yarn section and the weakly twisted yarn section is 10m.

Embodiment 2

[0028] Depend on figure 1 As shown, in the embodiment of the present invention, a variable twist yarn production device based on the variable twist yarn described in Embodiment 1 includes a front roller 1, a middle roller 2 and a rear roller 3, and both the middle roller 2 and the rear roller 3 are connected with the servo The motor 5 is electrically connected, the servo motor 5 is electrically connected with the servo motor controller 7, the servo motor controller 7 controls the operation of the servo motor 5, the servo motor controller 7 is also electrically connected with the front roller speed tracking device 6, and the front roller The speed tracking device 6 is electrically connected to the front roller 1 in two directions;

[0029] The front roller 1 and the front roller speed tracking device 6 are also electrically connected with the main motor 4 .

Embodiment 3

[0031] A variable twist yarn spinning method based on the variable twist yarn production device described in embodiment 2, the steps are as follows:

[0032] S1. The fiber is processed into roving that meets the requirements through the pre-spinning process. The spun yarn is spun by a ring spinning frame equipped with a variable twist yarn control device. The ring spinning frame is spun into a siro spinning frame and a compact spinning spun yarn One of the spinning machines and Siro compact spinning frames;

[0033] S2. Disconnect the transmission between the drafting roller and the spindle of the spinning frame, install a servo motor 5, and control the servo motor 5 to run by a servo motor controller 7, drive the drafting roller, and the original motor of the spinning frame drives the spindle;

[0034] S3. According to the process design, the output line speed of the front roller 1 is driven by the servo motor controller 7 to produce speed changes, and the spindle speed remai...

Abstract

The invention discloses a yarn with variable twist and a spinning method thereof, belongs to the technical field of spinning, and solves the problem that the thickness of yarns produced by an existingspinning technology cannot be maintained. The method is characterized in that a strong twist yarn section and a weak twist yarn section are included, the components of the yarn with variable twist are formed by staple fiber pure spinning or multi-component blending, the thickness of the yarn with variable twist maintains unchanged, the twist of the yarn varies in the axial direction of the yarn,and the twist ratio of the strong twist yarn section to the weak twist yarn section is 1.2-1.8. The prepared yarn with variable twist can ensure that the thicknesses of the yarns with variable twist are the same, and the lengths of the strong twist yarn section and the weak twist yarn section can be flexibly changed to help popularization and use.

Description

technical field [0001] The invention relates to the technical field of spinning, in particular to a variable twist yarn and a spinning method thereof. Background technique [0002] The original meaning of textile is taken from the general term of spinning and weaving, but with the continuous development and improvement of the textile knowledge system and subject system, especially after the production of non-woven textile materials and three-dimensional composite weaving technology, the current textile is not only a traditional manual Spinning and weaving also include clothing, industrial and decorative textiles produced by non-woven technology, modern three-dimensional weaving technology, and modern electrostatic nano-netting technology. [0003] With the development of textile and clothing fabrics in the direction of leisure and fashion, fancy yarns with structural changes are gradually favored by people because of their unique fabric styles. The structurally changing yar...
