Embodiment 1

[0057] 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 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 yarn that is naturally coupled and intertwined at the converging point is formed. Then move the U-shaped needle left and right back and forth with the set yarn gradient color waveform (trapezoidal wave) and wavelength (24m) to make a trapezoidal wave gradient, that is, ...

Embodiment 2

[0059] Take one yellow flame-retardant wool roving bobbin and one blue Nomex fiber roving bobbin, and the composite ratio is 50 / 50. After the two bundles of wool roving 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 the 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 α 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 yarn that is naturally coupled and intertwined at the converging point is formed. Then use the set yarn gradient color waveform (sine wave) and wavelength (16m), move the U-shaped needle left and right back and forth to make a sine wave gradient, and then measure the coverage c 5 , c 4 / 5 , c 4 value (see Table 1). It can...

Embodiment 3

[0061] Take one white polyester staple fiber roving bobbin and one natural silk fiber roving bobbin respectively, and the composite ratio is 50 / 50. After the two bundles of wool roving are positioned and gathered by the clusterer, they are fed into the nip of the front roller with the natural tension of drafting and 9mm 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 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 yarn that is naturally coupled and intertwined at the converging point is formed. Then move the U-shaped needle left and right back and forth with the set yarn gradient color waveform (frequency conversion triangular wave) and wavelength (64m) to make a frequency conversion triangle wave gradient, and then measure th...

Abstract

The invention relates to a front moving coupling wrapped gradient color spinning mechanism and a method and application thereof. The mechanism is formed by a U-shaped needle which is arranged in front of a front roller and can adjust the wrapping ratio of two staple fiber strips (S) leftward and rightward in a translation mode, a buncher which is used for the positioning of left and right staple fiber strips (S / S) and clustering the strips together, and a generation and executive mechanism which can move leftward and rightward in a translation mode. Through the leftward (rightward) translation of the U-shaped needle on a symmetrical point, the right (left) fiber strip conducts wrapping on the left (right) fiber strip, a resultant yarn displays a cyclic or non-cyclic gradient with the color or an apparent fiber component of the right (left) fiber strip as the principle, and the inter-wrapping mixing color ratio or the apparent fiber component ratio at the symmetrical position is the composite ratio of the prior fiber strips. The obtained gradient color yarn can be used for fabric with special colors and texture effects directly, or the obtained gradient component yarn can be woven into the fabric and then colored to obtain the special colors and the texture effects.

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 color spinning mechanism, method and application thereof. 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 the yarn; while ...
