Spinning technology will get further progress, among them annulus ingot spinning, close together spinning, turn a cup of spinning and eddy current spinning and system of short staple spinning will develop quickly.

One, annulus ingot is spun (Ring Spinning)

Annulus ingot is spun only then at 19 centuries, apply extensively already currently. Spinning quality reachs quite high level, applied limits and breed adaptability expand, already moved toward the manufacturing technology of high-tech.

The —— in showing skills of pair of annulus ingot spinning some problem cent narrates as follows:

1. Spun yarn decollations: Carry out a proof, rise ceaselessly as spinning speed, spun yarn broken end increases, flying destroyed spinning balloon to cause broken end to happen in weak link part. But to improve character of movement of spun yarn machine, must reduce flying, reduce spun yarn broken end.

2. A lot of flying are in clean base winding ministry time-sharing arises, this branch tears off gauze to provide avulsion yarn, and to the short fine hair with the tiny scattering in the workshop, create spun yarn broken end easily. In on machine of spun yarn of G33 annulus ingot 1000 spindle every 2 hours have 250 meters long gauze about outward be lost. Machine of spun yarn of G33 annulus ingot deserves to gauze of mechanical doffer servo is in charge of fire to run a system, the fiber in the yarn when through the experiment discovery eliminated bottom winding is many be lost phenomenon, and improved performance of movement of spun yarn machine.

Spun yarn workshop still must deserve to have first-rate air adjustment equips. Consider to make clear, machine of long model spun yarn is local broken end rises apparently, when with mouth of the 3rd aspiration the distance increases, broken end increases apparently, explain aspiration mouth amount ought to undertake adjustment.

Equidistance increases aspiration mouth amount, can improve position of movement of spun yarn machine, flying will enter — pace to improve as negative pressure air current, this indicates the potential of condition of movement of machine of annulus ingot spun yarn. The spinning factory of new design or the improvement that a few old spun yarn workshops can consider to suck wind.
