Four-channel hollow ingot fancy yarn forming device and method

Abstract

The invention provides a four-channel hollow ingot fancy yarn forming device and method. The yarn forming device comprises a first channel, a second channel, a third channel and a fourth channel. First and second twisting points are arranged on the channel; the first to fourth components are inter-twisted to form a fancy yarn main body through the first twisting points; a hollow ingot is arrangedat the second twisting points, and the fifth component on the hollow ingot is jointed with the fancy yarn main body to wrap and twist the fancy yarn main body. The device spins the fancy yarn in one step by implementing alternating drawing, inter-twisting and wrapping processes through a one-step method. By regulating the speed of feeding the decorative yarn and the core yarn synergically into thetwisting points, the linear density and the blending ratio of the decorative yarn, the twisting degree of the core yarn and switching of the corn yarn and the decorative yarn and the like, online changes of colors and shapes of bamboo joints, paunches, knots, rings and pigtails of the fancy yarn are achieved, so that the novel variety of the fancy yarn is expanded.

Description

technical field [0001] The invention relates to the technical field of spinning in textile engineering, in particular to a four-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.
