Four-channel alternating drafting, winding-twisting and coating ring-spun fancy yarn forming device and method

Abstract

The invention provides a four-channel alternating drafting, winding-twisting and coating ring-spun fancy yarn forming device and method. The four-channel alternating drafting, winding-twisting and coating ring-spun fancy yarn forming device comprises a first channel, a second channel, a third channel and a fourth channel; first twisting points and second twisting points are arranged on the channels; first component yarn, second component yarn and third component yarn are interactively wound and twisted through the first twisting points to form a fancy yarn body; and the fancy yarn body is coated and twisted through the second twisting points and fourth component yarn to form fancy yarn. According to the four-channel alternating drafting, winding-twisting and coating ring-spun fancy yarn forming device and method, alternating drafting, interactive winding-twisting and coating processes are implemented through a one-step method, the fancy yarn is spun through the one-step method, meanwhile, through the technological means of regulating and controlling the speed of collaboratively feeding decorative yarn and core yarn into the twisting points, regulating and controlling the yarn density and the blending ratio of the decorative yarn, regulating and controlling the twist of the core yarn, regulating and controlling switching of the core yarn and the decorative yarn and the like, thecolors and the forms of nubs, slub, knots, circles and braids of the fancy yarn are changed online, and the new 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 alternating drafting, twisting, and coating ring spinning fancy yarn forming device and method. Background technique [0002] Fancy yarn generally includes three components: core yarn, decorative yarn and fixing thread. Usually, the strength of fancy yarn is guaranteed by the core yarn, so the core yarn needs higher strength; the change of shape and color of fancy yarn is It is provided by decorative yarns, so colored yarns, slub yarns, and belly yarns are generally used for decorative yarns; the stability of the fancy yarn structure depends on the positioning of the fixing thread, so the fixing thread is usually thinner and stronger. [0003] The use of ring spinning equipment to make fancy yarns is mainly carried out on ring twisting machines. The production of fancy yarn by ring spinning usually adopts a three-step method. In the first s...
