The fiber aggregate is characterized in that: when spinning, the red sliver, yellow sliver and blue sliver obtained by the drawing process are fed through the upper carding device of the sliver feeding device. At this time, the red sliver, Yellow cooked sliver and blue cooked sliver are fed into the bell mouth through the left carding, the middle carded into the bell mouth, and the right carded into the bell mouth respectively. The strips are firstly combed between the upper and lower comb teeth on the rear side of the bell mouth through the left open comb, the middle open comb into the bell mouth, and the right open comb into the bell mouth. Then, the upper and lower comb teeth on the front side of the bell mouth are fed into the bell mouth through the left split comb, the middle split comb is fed into the bell mouth, and the right split comb is fed between the upper and lower comb teeth on the front side of the bell mouth. The sliver, yellow sliver and blue sliver are carded into fibers, and then sucked into the carding device and under the action of the negative pressure of the left negative pressure suction port, the middle negative pressure suction port and the right negative pressure suction port. In the connecting device between the twisting devices, at this time, the negative pressure of the left negative pressure suction port, the middle negative pressure suction port and the right negative pressure suction port is adjusted through the left negative pressure control valve, the middle negative pressure control valve and the right negative pressure control valve. In the connecting device, with the decrease of the inner diameter of the connecting device, the inhaled red, yellow and blue fibers conduct initial The mixed fibers are continuously sucked into the lower twisting device under the action of the negative pressure of the twisting negative pressure suction port. At this time, the negative pressure generated by the negative pressure fan enters the twisting cavity through the twisting negative pressure suction port. Spiral channel, and then generate a clockwise or counterclockwise vortex flow in the spiral channel, and then twist the roving with Z twist or S twist on the inhaled mixed fiber, and then obtain the colored roving with weak twist, and the obtained colored roving It is output from the lower circular surface of the twisting chamber, and then enters the roving drafting device. At this time, the front top roller, middle top roller and rear top roller of the roving drafting device are pressed down and are respectively connected with the front roller, middle roller and rear roller. Pressing and contacting closely, the main motor drives the front roller to rotate, and then drives the front top roller to rotate synchronously. The front roller rotates and then drives the middle roller to rotate through the first gear, and then drives the middle top roller to rotate synchronously. The roller rotates, and then drives the rear top roller to rotate synchronously. The colored roving first enters the rear roller pair, then enters the middle roller pair, and is drafted by the rear drafting area formed between the rear roller pair and the middle roller pair, and then enters the front roller. Yes, under the drafting action of the front drafting area formed between the middle roller pair and the front roller pair, a colored fiber sliver with extremely weak twist is obtained, and the colored fiber sliver is twisted under the action of the twist of the spun yarn to obtain the final Colored yarns, in which the twist of the roving and the twist of the spun yarn are in the same direction.
