Description
Technical field
The invention belongs to field of textiles, is related to a kind of spinning method for genuine of enveloped composite yarn and the equipment using this method, tool
Body is related to a kind of spinning method for genuine of composite yarn of endless tow looping Gas in Ultra-thin Metal Wires and the equipment using this method.
Background technology
The fasciated yarn of comprising metal wire is widely used to the neck such as textile garment, mechano-electronic, space flight and aviation, energy conservation and environmental protection
Domain, particularly Gas in Ultra-thin Metal Wires/chemical-fibres filaments enveloped composite yarn are usually used in high-performance textile product, high-tech aerospace components and surpass
Thin electronic wire etc..But the application of these high-technology fields is to the covering property of wire/chemical-fibres filaments enveloped composite yarn
Energy, evenness quality etc. propose harsh requirement, are difficult to meeting these requirements using the processing method of traditional approach at present
On the basis of complete the looping of microfilament and wire.
Traditional fasciated yarn processes generally use Novelty twisters, its principle is piece tension rail of pile warp after heart yarn passiveness back yarn
And pressure roller, and the front draft zone being made of three row rollers and first break draft area are passed sequentially through, again pass by one group of pressure roller and tension rail
Afterwards, with the outsourcing yarn unwind out on rotating hollow spindle, together into hollow spindle core, the rotation of hollow spindle is passed through
So that outsourcing yarn is looped around heart yarn outer layer, finally finished yarn bobbin is obtained via winding mechanism.Its gained fasciated yarn heart yarn be in
Stretched straight parallel shape, remaining weak twist without the twist or only caused by outsourcing, outsourcing yarn is twist around overlaying on core yarn
Outside.When heart yarn is Gas in Ultra-thin Metal Wires, since contact produces excessive frictional resistance in process, easily occur abrasion and
Broken end, causes overall looping technique unstable, reduces production efficiency；When outsourcing yarn is microfilament beam, due to endless tow without
Sth. made by twisting or weak twist, it is easily scared to cause to break end during rotation is unwind.In addition, because Gas in Ultra-thin Metal Wires and microfilament surface
Friction coefficient is small, in order to increase cohesive force between the two, it is necessary to increase the tightness of outsourcing yarn, and the component of traditional looping effect
Only rotatable hollow ingot, structure is simple and crude, lacks effective looping control device, and the spun fasciated yarn structure of institute is excessively fluffy
Pine.And during looping, looping point is typically in the inside of hollow bolster, is unfavorable for controling effectively to its displacement,
The thickness of yarn knot spun out is frequent, and bar is done extremely irregular.
Therefore, a kind of great realistic meaning of spinning method for genuine for the enveloped composite yarn that can overcome drawbacks described above is developed.
The content of the invention
The purpose of the present invention is overcome the prior art easily to be worn when spinning Gas in Ultra-thin Metal Wires/chemical-fibres filaments enveloped composite yarn
