Embodiment 1

[0060] Take one black and one white cotton fiber roving bobbin, and the composite ratio is 50 / 50. After the two bundles of cotton roving are positioned and gathered by the cluster, they are fed into the nip of the front roller with the natural tension of the drafting and an 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 gathers at point A to form a convergent point coupling and wrapping gradient structure yarn 71. Move the trident needle 1 to make it reciprocate left and right on the variable-span arc trajectory line 9, and simultaneously rotate clockwise and counterclockwise around the center of mass axis. Then move the trident needle 1 to make a gradual change from left to right with the set yarn gradient color waveform (trapezoidal wave) and wavelength (32m), that is, the trapezoidal wave is the length of the gradient yarn se...

Abstract

The invention relates to a variable-span track-type coupling gradient-color high-elastic-difference structure spinning mechanism and method and application. The mechanism is composed of a trifurcate needle which is arranged in front of a front roller, can perform initial converge angle adjustment on a natural convergent point axis and performs left-right movement in the wrapping fiber strand convergence angle axis direction in a variable-span arc-shaped trajectory mode, a pair of bunchers for positioning, collecting and gathering left and right short fiber strands (S / S) and a generating and executing mechanism moving in a variable-span arc-shaped track. Left (right) fiber strands are wrapped by the right (left) fiber strands through leftward (rightward) translation of the trifurcate needle moving along the variable-span arc-shaped track, while resultant yarns show periodic or non-periodic gradual change oriented to right (left) fiber strand colors or apparent fiber components. The obtained gradient-color yarns can be directly used for fabrics having special colors and function texture effects, or the obtained gradient-component yarns can be knitted into fabrics, then the fabrics are dyed to obtain the fabrics having special colors and function texture effects.

Description

technical field [0001] The invention relates to a coupling-wrapping gradient color spinning technology and its application, and belongs to the technical field of ring spinning, in particular to a variable-span orbital coupling-wrapping gradient color and low elastic difference structure spinning technology. Background technique [0002] The spinning method of controllable gradient color directly on the spinning machine appeared after the composite spinning technology on the ring spinning machine in the 1940s and 1950s, that is, staple fiber / short fiber strand (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 t...
