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 one natural color stainless steel fiber tube and one white cotton fiber tube, and the composite ratio is 50 / 50. After the two bundles of roving are positioned and gathered by the clusterer, they are fed into the nip of the front roller with the natural tension of the drafting and 8mm spacing. For details, see figure 1 shown. After the two-axis fiber strip exits the nip of the front roller, the twist coefficient α tex is 340, and the spindle speed is 10500rpm, 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 located at the center point of the U-shaped needle. A structural functional yarn that is naturally coupled and intertwined at the converging points is formed. Then move the U-shaped needle left and right back and forth with the set yarn gradient function waveform (trapezoidal wave) and wavelength (24m) to make a tra...

[0056] Take a gold-plated polyester filament bobbin and a polyester-cotton blended roving bobbin each, and the composite ratio is 50 / 50. After the two bundles of fibers are positioned and gathered by the bundler, they are fed into the nip of the front roller with the natural tension of the drafting and a distance of 10mm. For details, see figure 1 shown. After the two-axis fiber strip exits the nip of the front roller, the twist coefficient a tex is 345, and the spindle speed is 11500rpm and naturally gathers at point A. Move the U-shaped needle so that the natural convergence point A is located at the center point of the U-shaped needle. A structural functional yarn that is naturally coupled and intertwined at the converging points is formed. Then move the U-shaped needle left and right back and forth with the set yarn-forming gradual change function waveform (sine wave) and wavelength (16m) to make a sine wave gradual change, that is, move left to point B with a sine wave...

[0058] Take one white polyester yarn bobbin and one white cotton roving bobbin, and the composite ratio is 50 / 50. After the two bundles of fibers are positioned and gathered by the bundler, they are fed into the nip of the front roller with the natural tension of the drafting and a distance of 9mm. For details, see figure 1 shown. After the two-axis fiber strip exits the nip of the front roller, the twist coefficient α tex It is 320, and the spindle speed is 10000rpm and naturally gathers at point A. Move the U-shaped needle so that the natural convergence point A is located at the center point of the U-shaped needle. A structural functional yarn that is naturally coupled and intertwined at the converging points is formed. Then move the U-shaped needle left and right back and forth with the set yarn gradient function waveform (variable frequency triangular wave) and wavelength (64m) to make frequency variable triangular wave gradual change, that is, the variable frequency t...

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-wrapping gradient structure spinning mechanism, method and application thereof, belonging to the technical field of ring spinning, in particular to a coupling-wrapping gradient function spinning mechanism, method and application thereof. Background technique [0002] The spinning method with controllable gradual change function directly on the spinning machine appeared after the composite spinning technology on the ring spinning machine in the 1940s and 1950s, that is, staple staple / short staple staple (S / S) The composite spinning method was followed by innovative spinning methods, almost at the same time as the filament tow / short fiber (F / S) composite spinning. In the late 1960s and 1970s, it was still a laboratory technology and not disclosed. The most essential difference between gradient color spinning and compound spinning is that in gradient color spinning, the fiber content changes along the circumference of ...
