Problems solved by technology

However, for the short fiber slivers, the air jet method will firstly cause flying flower color mixing defects and fiber arrangement disorder to be blurred, that is, the passivation and gelatinization of gradient colors; secondly, the air jet will significantly increase energy consumption and noise; Third, there is also the above-mentioned method that cannot achieve complete wrapping, that is, wrapping of 0 or 1

Embodiment 1

[0054] Take a natural stainless steel fiber tube and a white cotton fiber tube, and the compounding ratio is 50 / 50. After the two bundles of rovings are positioned and gathered by the bundler, they are fed into the front roller jaws with the natural tension of drafting and 8mm spacing, see details figure 1 shown. After the two-axis fiber strip exits the front roller jaw, the twist coefficient α tex It is 340, and the spindle speed is 10500rpm and it naturally converges at point A, and the convergence angle of convergence point A is about 60°, which is on the center line. Move the U-shaped needle so that the natural convergence point A is at the center of the U-shaped needle. It forms a structural functional yarn that is naturally coupled and twisted at the convergence point. Then move the U-shaped needle left and right back and forth to make a gradient of the trapezoidal wave with the set yarn-forming gradient function waveform (trapezoidal wave) and wavelength (24m), that ...

Abstract

The invention relates to a gradual change function spinning mechanism with front movable coupling wrapping, a method and application. The mechanism is composed of a U-shaped needle, a pair of bunchers and a happening and executing mechanism, wherein the U-shaped needle is arranged in front of a front roller, can achieve left-right translation adjustment, has different characters or functions and has the Sa / Sb wrapping ratio of two short fiber strands, the pair of bunchers are used for left-right short fiber strand Sa / Sb positioning and bundling gathering, and the happening and executing mechanism achieves left-right translation. The right(left) fiber strand performs wrapping on the left(right) fiber strand through left(right) translation of the U-shaped needle at the symmetric point, and spun yarn resultant yarn has periodic or nonperiodic gradual changes adopting the right(left) fiber strand function or apparent fiber components as main parts, and the wound mixing ratio at the symmetric position or the apparent fiber component ratio is the composition ratio of two original fiber strands. The obtained gradual change color yarn can be directly used for a fabric with the special function and the texture effect.

Description

technical field [0001] The invention relates to a coupling and wrapping gradient structure spinning mechanism, method and use thereof, belonging to the technical field of ring spinning, in particular to a coupling wrapping gradient function spinning mechanism, method and use. Background technique [0002] The spinning method with controlled gradient function directly on the spinning machine appeared after the compound spinning technology on the ring spinning machine in the 1940s and 1950s. Innovative spinning methods followed the composite spinning method, around the same time as the filament tow / staple sliver (F / S) composite spinning. In the late 1960s and 1970s, it was still a laboratory technology and was not disclosed. The most essential difference between gradient color spinning and composite spinning is that in gradient color spinning, the content of fibers changes along the circumference of the yarn; while in composite spinning, the distribution of fibers changes in ...
