The stops behind the false twist device move synchronistically with the yarn, and stop when the twirling reverse dot is shaped in the yarn. At least one another stops is jointed with yarn and alternate S twisting and z twisting is provided by the airflow with one or more air jets used as false twist device.
Description
The present invention relates to a kind of be used to make have add alternately that S twists with the fingers and multifilament (yarn) method (Filamentgarn) of Z sth. made by twisting, wherein at least one silk thread two space certain distance settings stop move between the twister, and be arranged on the false-twisting device that stops between the twister by at least one and twist with the fingers alternately for silk thread S and the Z sth. made by twisting, they are by means of a shaping device setting after the silk thread direct of travel is connected false-twisting device, wherein after the silk thread direct of travel is arranged on false-twisting device stop twister and silk thread is synchronized with the movement, and keep stopping twisted engaging with silk thread, till the twisting reversal point obtains determining in silk thread at least, and another twister that stops that stops a distance, twister back that is connected described motion keeps stopping twisted engaging with silk thread at least, and and it continue motion together, up to give by false-twisting device silk thread reciprocal twisted till.
Method by known a kind of this class of DE-198 27 870 C1.In this method, feed and give a smooth multifilament to handle.Silk thread must stretch in an independent operation before this processing stage, so that for example improve silk thread intensity and/or adjust shrinkage.This additional operation causes additional expense.Because the characteristic of finished product silk thread is influenced by this preliminary stage parameter greatly, must stock the infed material that differently stretched for the product that meets user's specific (special) requirements definitely.
Therefore the objective of the invention is, optimization starts described method aspect different.
Realize by such method that by this purpose of the present invention the jet thrust that adopts one or several motion is as false-twisting device, alternately acting on air-flow on the silk thread along tangent line and give the S that silk thread replaces and twist with the fingers and the Z sth. made by twisting by them with opposite direction.
Shower nozzle compares L because the motion that its smaller physical dimension reduces to twist the initiation point and be each positioned at its back stops the distance between the twister otherwise strengthen length when same machine dimensions
0/ L
1(referring to Fig. 2 and 5).Both the twist that can reach can be increased thus, speed of production can be improved again.Twisting both can be by a shower nozzle that has an alternation moment direction, also can by two mutually the shower nozzles that respectively carry the different rotary direction of serial connection carry out.By adopting shower nozzle no longer to need moving parts, make switching frequency not become the limiting factor in the speed of production, significant wearing and tearing do not appear simultaneously yet.
Next starts described method and can optimize by such method by the present invention, makes to stand in the zone of silk thread before first stops twister to stretch.
Stretch and to be integrated in the handling process by loading onto another transport before stopping twister at first.Can feed to handling process in this way and give suitable raw material, predraft multifilament (POY or LOY).In the drawing zone that can make stretching cold or heat, can exert one's influence to the numerous characteristics of finished product silk thread.Integratedly saved an additional work step, be used for the machine and the expensive shelter cost of feeding of this work step to material.
The embodiment that this method is good is represented in the dependent claims.

Schematically illustrate the structure of finished product multifilament among Fig. 1.It alternately has band S silk thread section 1a that twists with the fingers and the silk thread section 1b that is with Z to twist with the fingers.Have two silk thread section 1a of twisting in the other direction, having one to twist with the fingers between the 1b respectively to reversal point 2, use by method reversal point of the present invention spread length longitudinally can but whether must do very for a short time.Silk thread section 1a, the length of 1b can change.Should adopt smooth and Texturized multifilament as feeding to material.Fig. 2 represents the schematic diagram of technological process.Silk thread 1 ' move to B from A along silk thread direct of travel C.Silk thread arrives transport 6 as the finished product multifilament 1 that S alternately twists with the fingers and Z twists with the fingers that has as shown in fig. 1, and this transport can advantageously directly be made winder unit.One first is stopped twister 7 and fixedly installs, and especially can make transport or silk thread brake.Fixing stop twister 7 after distance be L
0The place is provided with a shower nozzle 8 as false-twisting device at least, can give the silk thread 1 ' alternately S of variation twisting and Z twisting in turn with this shower nozzle.After false-twisting device 8, be provided with one have a plurality of along silk thread direct of travel C move stop twister 3 stop twist device 9.Each stops twister 3 respectively by at least two coefficient clamping area 3a, and 3b constitutes.Its extending longitudinally length depends on later application target.The reverse position (fabric) on finished product weaving surface that has minimum spread length is not noticeable as fault, and desirable effect can be caused in long reverse position on the weaving surface.Stop twister 3 and can be installed on the belt 10a or 10b of annular driving, thereby it can be return.Also can adopt other conveyers for stopping twister 3.Motion stop distance L between the twister 3
2Expression.The distance L 2 of stopping between the twister 3 of motion can change, and perhaps motion stops twister 3 and conveyer 10a, but the connection between the 10b is a switch.Stop twister 3 and pass a setting device 11, shaping device is made up of the cooling zone 5 that a thermal treatment zone 4 and is connected the back.Here stop the spacing L of twister
2Length L less than shaping device 11
3Guarantee in this way, give silk thread 1 ' alternately reverse, and when finished product silk thread 1 leaves shaping device 11, add heat setting further two twisting that stop temporary set between the twister 3.
For this method is worked as far as possible effectively, should make and stop twister 3 at as close as possible false-twisting device 8 places and silk thread 1 ' entering stops splicing closes, then with silk thread 1 ' synchronously continue motion.Can give twisted direction by false-twisting device 8 conversion along with stopping the each new joint of twister.Stop between the twister 3 S twisted filament line segment 1a and the Z twisted filament line segment 1b that temporary transient " setting " replaces at two, be in the silk thread 1 of twisted state ', pass through cooling zone 5 then at first by the thermal treatment zone 4.Have only below silk thread is cooled to uniform temperature the back 5 just unclamping clamping when coming out from the cooling zone.By fixing stop different distance L0 between twister 7 and the false-twisting device 8 and false-twisting device 8 and with it from the different distance of stopping between the twister 3 of motion recently forms the different twists, the twisting revolution on false-twisting device 8 front and back unit lengths just.But in process of production only false-twisting device 8 and from nearest motion stops that part between the twister is twisted to obtain setting.Just backtwisting and sth. made by twisting are tight in theory for silk thread in stopping twister 7 and false-twisting device 8 zones.Therefore false twisting is divided into two and reciprocally really twist, and the twisting that wherein at every turn only is positioned at after the false-twisting device obtains formalizing.For this twisting no longer is subjected to the reverse influence of twisted direction subsequently, twisted direction only subsequently stop twister and silk thread 1 ' ability conversion after engaging.Here each next one stops twister and should move to closely by last false-twisting device 8, so that spacing L1 maintenance is as much as possible little.That is to say silk thread section backtwisting and the rotation in the opposite direction again that when twisted direction changes, at first is in the area L 1.Short more to the distance that begins to change twisted direction, the inventive method work must be effective more, as shown in Figure 4.
The same technological process that is used for giving twisted shower nozzle 8 and 8 ' time that Fig. 3 is provided with before and after being illustrated in and adopting two.Here each shower nozzle is used for a twist direction.Shower nozzle can and reduce energy consumption and optimize better for its function like this.
Be illustrated in false-twisting device fore-and-aft clearance L among Fig. 4
0And L
1Theory relation with the twist.Here can find out the advantage that adopts shower nozzle to compare significantly with the false-twisting device of pinching.Adopting shower nozzle time interval L
1Can be about 20mm.For the typical numerical value of the false-twisting device of pinching is 120mm.
Fig. 5 represents to have the schematic diagram of the method for preposition stretching device.Do not stretch or the silk thread 1 of predraft and " between transport 7 and 12, stretch, then flow in addition false twisting of handling process.Can carry out the hot-stretch in the thermal treatment zone 13, or carry out cold stretch.The characteristic of silk thread 1 after can directly influencing by means of the parameter of here adjusting.The type of a preposition drawing zone and false-twisting device is irrelevant.
Fig. 6 represents to stop twister, and it does not have moving parts just much of that fully.Here silk thread be clamped in clamping area 14 and 14 ' between.Clamping area 14,14 ' itself can make rectilinear or planar shaped.The power that clamps silk thread only produces by the spring force of used clamping element.Silk thread can pass through clamping area 14,14 ' between the component traction of silk thread tractive force, perhaps a special switching device is cancelled clamping action in short time when penetrating and pass.This sketch is just represented a kind of form of implementation of this clamping element for example.
Fig. 7 represents a kind of superior structural of clamping area.By adopting three clamping area 15a, 15b, 15c owing to form twine and have improved the clamping effect and stop twisting with the fingers function when less normal force.Thereby get rid of the damage of silk thread fully.
