Description
Technical field
The present invention relates to textile technology field, particularly relate to a kind of unwinding yarn system.
Background technology
With stainless steel etc. for the simple metal fabric of representative is because of advantages such as three-dimensional bending when its high strength, corrosion-resistant, high temperature resistant, anti-cutting, covering surface are good, just obtaining applying more and more widely in fabrics for industrial use field.Especially in recent years, the fineness of metal fibre can reach micron order, and the textile process performance of fiber obtains further optimization, makes the textile processing of simple metal fiber become possibility.But owing to being obviously different from the performance characteristics of conventional textile fabric, making the textile process process of simple metal fiber also there is various problem has to be solved, especially needs more difficult for the knitting process of yarn bends lopping in process.The circular knitting machine weaving of simple metal fiber is the current difficulties being devoted to solve.
The textile process performance feature of simple metal fiber is obviously different from traditional textile fabric.The most outstanding performance characteristics of simple metal fiber mainly comprises about 6 times that fiber quality density is conventional textile fabric, and between fiber and fiber, between fiber and loop-forming element, frictional resistance is much larger than conventional textile fabric.These performance characteristics make the circular knitting machine production process of simple metal fiber there is many difficulties.In the textile process process of simple metal fiber, rational unwinding condition send the basis of yarn on request, is to ensure that simple metal fiber normally completes the most important condition of weft-knitted process.
But, on the one hand, because production metal fibre being applied to circular knitting machine is a new field; On the other hand, compared with simple metal fiber yarn, traditional weaving yarn qualities density is little, and yarn deadweight is little, and in unwind process, frictional resistance is little.Therefore, in metal fibre unwind process, cause the factor of significant impact can not produce great impact on unwinding when conventional textile fabric weaves, correspondingly, in prior art, there is no the special unwinding system for metal fibre yarn.
When using traditional circular knitting machine to carry out unwinding to metal fibre yarn, following problem will be there is: when yarn is along horizontal aspect unwinding, air ring will be rotarily formed around bobbin, the shape of deadweight to air ring of yarn has certain influence, yarn and bobbin surface are rubbed, yarn when shaft centre line is upper and lower and the friction yarn segment length of bobbin surface and unwinding condition inconsistent, cause tension force irregular, unwinding change in resistance is large.In order to address this problem, the position of outer creel first guide eye of the machine that current circular knitting machine generally uses is slightly higher than bobbin shaft center line, about high about 10cm.But this regulative mode is not suitable for the simple metal fiber yarn that mass density is about 6 times of conventional textile fabric, and, this regulative mode will cause guaranteeing yarn along the shaft centre line unwinding of yarn cylinder and unwinding can be caused time yarn cylinder cross section on diverse location unwinding condition inconsistent.
In addition, multiple solution is also proposed in prior art, if Authorization Notice No. is the Chinese utility model patent of CN200940189Y, describe a kind of steady yarn device of guide tubular type creel switch of circular knitting machine, this patent can stablize the delivery of yarn, nationality tunes by regulating wheel the angle changing upper and lower steady yarn bar, and then can adjust the delivery tension force of yarn, to be applicable to the yarn delivery of heterogeneity, specification; Publication number is the Chinese invention patent of CN1200152A, discloses a kind of circular knitting machine yarn feeder, is driven be used for lock around the revolving part of yarn and a mechanical type unwinding for revolving part by motor, to be wound up into by yarn to store in yarn device by revolving part; Publication number is CN101023013A Chinese invention patent application, discloses a kind of yarn feeding device of control yarn tension of circular knitting machine, regulates yarn tension by the cooperation regulator of fixing storage member, tension link.But these improvement opportunity existing, not only complex structure, adds equipment cost, and the horizontal unwinding fundamentally not changing the outer creel of circular knitting machine machine is the vertical unwinding meeting simple metal yarn feature, is not suitable for the unwinding feature of simple metal yarn.
Therefore, need to design a kind of unwinding yarn system being specially adapted for simple metal unwinding yarn condition.
