Five-channel hollow-spindle fancy yarn forming device and method

Abstract

The invention provides a five-channel hollow-spindle fancy yarn forming device and method. The yarn forming device comprises a first channel, a second channel, a third channel, a fourth channel and afifth channel; first component yarn, second component yarn, third component yarn, fourth component yarn and fifth component yarn are alternately twined and twisted at a first twisting point to form afancy yarn main body; a hollow spindle is arranged at a second twisting point, and the sixth component yarn on the hollow spindle and the fancy yarn main body intersect and the fancy yarn main body iscoated. Alternate drafting, alternate twining and twisting and coating processes are performed in one step, and one-step spinning of fancy yarn is achieved; besides, on-line change of colors and shapes of the fancy yarn such as slub yarn, big-belly yarn, knot yarn, loop yarn and pigtail yarn is achieved with technological means of adjusting and controlling the speed at which decorative yarn and core yarn are cooperatively fed into the twisting points, the line density and blending ratio of the decorative yarn, twist of the core yarn, switching between the core yarn and the decorative yarn andthe like, and new varieties of the fancy yarn are expanded.

Description

technical field [0001] The invention relates to the technical field of spinning in textile engineering, in particular to a five-channel hollow spindle fancy yarn forming device and method. Background technique [0002] The production of fancy yarns on hollow spindle spinning machines usually adopts a two-step method. In the first step, the core yarn, decorative yarn and fixed yarn are spun separately; in the second step, the core yarn fed at different speeds is False-twisting of the decorative yarn, through the overfeeding of the decorative yarn to the core yarn, the decorative yarn is twisted on the core yarn to form knots, circles, braids and other patterns, and then the fixed yarn unwound from the hollow spindle is used to wrap the The formed flower knot is fixed to form a hollow spindle fancy yarn. The main problems in the production of fancy yarns on hollow spindle spinning machines are as follows: [0003] 1) The color change of the fancy yarn cannot be controlled wh...

AI Technical Summary

Problems solved by technology

[0003] 1) The color change of the fancy yarn cannot be controlled when the hollow spindle is spinning the fancy yarn: In order to realize the color change of the fancy yarn, one is to control the mutual wrapping relationship of the decorative yarn, the core yarn and the fixed yarn, and the other is to control the color change of the fancy yarn. Control the color of the decorative yarn

The traditional hollow spindle spinning machine still lacks the means to control the intertwining relationship of decorative yarn, core yarn and fixed yarn in the production of fancy yarn, and it is also unable to control the color of decorative yarn, so it is impossible to control the change of fancy yarn color;

[0004] 2) The size and color of knots, loops, and braids cannot be controlled when hollow spindles spin fancy yarns: hollow spindle fancy yarns contain three components (core yarn + decorative yarn + fixed yarn), of which decorative yarn It is the main body to form fancy knots, loops, and braids. The traditional hollow spindle spinning machine cannot control the thickness and color changes of decorative yarns online, so it is impossible to control the size and color changes of knots, loops, and braids;

[0005] 3) The combination of the core yarn and the decorative yarn cannot be adjusted when the hollow spindle spins the fancy yarn: when the hollow spindle spins a three-thread fancy yarn including (core yarn + decorative yarn + fixed yarn), only one decorative yarn can be realized. The simple combination of yarn and core yarn cannot realize multiple combinations of multiple decorative yarns and multiple core yarns, so the online regulation of the combination of decorative yarns and core yarns cannot be realized

[0006] 4) When the hollow spindle spins fancy yarns, it is impossible to control the change of the covering ratio of the core yarn, decorative yarn and fixed yarn: when the hollow spindle spins a three-thread fancy yarn containing (core yarn + decorative yarn + fixed yarn), at There is no control means in the process of twisting the core yarn and decorative yarn and then covering with fixed yarn, so it is impossible to control the change of core yarn, decorative yarn and fixed yarn covering ratio online

[0007] 5) Low efficiency, high production cost, etc.

[0008] Due to the above-mentioned problems in the hollow spindle spinning machine, it is difficult to change the wrapping structure, shape, color, The style and feel cannot meet the needs of fancy yarn clothing fabrics with various shapes, rich and delicate colors, and smart and avant-garde styles.
