Abstract
The invention relates to an unstretched multifilament yarn made of a PET type aromatic polyester containing a polyoxyalkylene polyether and an organic ionic compound is stretched and simultaneously false-twisted under specific conditions. The false twisting is stably conducted at a high speed without causing section deformation or fluffing to thereby give a yarn of a fibrous structure having an excellent texture and unsusceptibility to fibrillation. Thus, a polyester false twist yarn having excellent long-term antistatic properties is produced. The unstretched yarn in combination with an unstretched polyester yarn comprising a poly(methyl methacrylate) polymer and/or polystyrene polymer is stretched and simultaneously false-twisted under specific conditions to thereby stably produce at a high speed a composite false twist yarn which is free from fluffing, has excellent bulkiness, gives a spun-yarn feeling, and has excellent long-term antistatic properties. This composite false-twisted yarn is useful especially in applications where static electricity is desired to be diminished, such as school uniforms, uniforms, and dust-proof clothing.

In the melt spinning stage, preferably above-mentioned composition of aromatic polyester is discharged from spinning spinning head fusion, carry out cooling curing and form the long filament shape, with each long filament plying, giving the finish that needs, is to draw under 2000～4500m/ branch, the special 2500～3500m/ condition of dividing at spinning speed.
At this moment, the birefringence of the not stretch yarn (multifilament) that has spinned need be in 0.02～0.05 scope.When birefringence less than 0.02 the time, the tension force that false twisting adds man-hour is low, is easy to produce bound edge (サ one ジ Application グ), and cause because the heat setting inequality that reeling causes, and form the uneven bad reason of dyeing, and closely add the draw ratio rising in man-hour and form tender yarn in false twisting, not preferred therefore.On the other hand, when birefringence greater than 0.05 the time, be easy to take place the raw yarn fluffing, make operation inharmonious, be not preferred therefore.
In the method for the invention, preferably in the operation of spinning and/or draw false twisting processing, carry out the interleaving treatment of sliver by air turbulence.Above-mentioned air interleaving treatment also can be carried out with other operations different with draw false twisting processing, but preferably as shown in Figure 1, interlacing nozzle (4) is set in the draw false twisting processing unit (plant), and just implements this processing in the draw false twisting first being processed.Can suppress to produce fluffing thus, the influence of bringing for the operability of finished yarn.And then, under false twisting, the sliver after the heat setting is implemented air by the interlacing nozzle (not having diagram) that utilizes other and interweave, can fully mix fibre and interweave, make yarn length direction homogenising.By this effect, can form and have at the antistatic property of yarn length direction homogenising and have the finished yarn of feeling of high class.
In the method for the invention, preferably just for example hang on as shown in Figure 1 the draw false twisting processing machine and make and have curling polyester false twist yarn with 2 segmentation heaters at the not stretch yarn that the draw false twisting first being processed is implemented interleaving treatment.And in the example of Fig. 1, above-mentioned polyester not stretch yarn (1) is drawn from package (パ ッ ケ one ジ), carries out the air interleaving treatment through thread-carrier (2) and by the interlacing nozzle (4) that is arranged between 2 pairs of feed rollers (3,3 ').Here, the not stretch yarn that carries out interleaving treatment on one side is stretched to specified multiple between feed roller (3 ') and the 1st outlet roller (8), by the false twisting instrument (7) of 3 spool friction circle dish-types rotating twist on one side.At this moment, false twisting instrument (7) uses following such instrument, that is, the material of disk that this instrument is positioned at the hypomere at backtwisting position is pottery, the contact length of this disk and mobile sliver is 2.5～0.5mm, and the diameter of this disk be adjacent its top disk diameter 90～98%.
Therebetween, sliver is used coldplate (6) cooling of downstream side after utilizing the 1st section heater (5) to carry out heat setting under the twisting state, and carries out backtwisting by false twisting instrument (7).And then, mobile sliver carries out heat-set treatment again with the 2nd section heater (9) that is arranged between the 1st outlet roller (8) and the 2nd outlet roller (10) as required, and then after implementing air and interweaving, be wound into bobbin shape package (12) with batching licker-in (11), thereby be made as the antistatic polyester false twist yarn of purpose.
Consider and carry out draw false twisting processing under high speed, the 1st section heater (5) and the 2nd section heater (9) all are preferably contactless.Especially, the 2nd section heater (9) omits SW-OFF (not using) mostly, but according to the needs of desired liquor style of finished yarn etc., also can use.
In the method for the invention, as mentioned above, importantly false twisting instrument (7) is 3 friction circle dish-types as shown in Figure 2, and the disk that is positioned at the hypomere at its backtwisting position is the disk of pottery system, the diameter of this disk be adjacent its upper reaches disk diameter 90～98%, the contact length that makes this disk and mobile sliver is 2.5～0.5mm.Promptly, false twisting instrument (7) shown in Figure 2 is the instrument that 3 friction circle dish-types that 2 false twisting disks (13) form are installed respectively on 3 rotating shafts (15), each rotating shaft (15) rotates with fixing speed by the synchronous belt (16) that drives with driving belt (17), thereby makes false twisting disk (13) rotation on each.In the method for the invention, the disk of the hypomere that is arranged in the backtwisting position at least in the false twisting disk (13) (the example of Fig. 2 be mounted in the left side spin rotating shaft below disk) be the pottery system, and the diameter of this disk be adjacent its upstream side disk (in the example of Fig. 2, be mounted in central rotating shaft below disk) diameter 90～98%.And should pottery rounding dish and the contact length of mobile sliver be 2.5～0.5mm.
The disk material of hypomere is a pottery in the false twisting instrument (7), and this angle from the disk wearing and tearing considers it is preferred.In addition, knowledge based on people of the present invention, the contact length that makes this disk and mobile sliver is 2.5～0.5mm, when this sliver in twisting end, rolled state enters last backtwisting position, can do one's utmost to reduce the contact area of this disk and sliver, and reducing resistance, this is being effective aspect remarkable minimizing fluffing.Similarly, find by the disk diameter that makes hypomere be adjacent its top disk diameter 90～98%, can reduce the resistance when making guide shift to next step (that is, heat setting), sliver can move smoothly.
In the method for the invention, owing in the long filament that constitutes the sliver that do not stretch, contain above-mentioned 2 kinds of antistatic additive, thereby the method according to this invention, originally be easy to produce the situation of the fluffing that causes by draw false twisting processing, can significantly reduce the generation that draw false twisting adds the processing fluffing in man-hour by adopting above-mentioned condition.Yet, in the time of outside this scope, producing the processing fluffing, the quality that forms for weavability, easy zbility, fabric product causes dysgenic major reason.People of the present invention carry out various researchs, and the result shows in the processing of the draw false twisting of the inventive method, and making the mobile sliver and the contact length of hypomere disk is 2.5～0.5mm, and this angle from remarkable minimizing processing fluffing considers it is effective especially.
False twisting processing temperature among the present invention need be 170～300 ℃.When this temperature during less than 170 ℃, crimp property is low, and liquor style is hard, when greater than 300 ℃, extremely carries out the flattening of finished yarn, produces the processing fluffing, is not preferred therefore.The device that has a contactless heater when use is during as false twist processing machine, and the design temperature that preferably makes the 1st section contactless heater is 170～300 ℃ and heat-treats like this.And, here so-called suitable heter temperature is set according to commercially available false twist processing machine (Supreme Being people's making mechanism 216 hammers are built HTS-15V), suppose its be contactless 1.0～1.5m length, yarn speed for the 800m/ branch～etc. the false twist processing machine of type, therefore, for the situation of using special heater or processing with ultraspeed etc., should suitably adjust design temperature certainly.
And, the heat treatment time of sliver in the 1st section heater is as long as suitably set according to kind, its length and its temperature etc. of heater, when heat treatment time too in short-term, it is insufficient that the crimp percent of finished yarn is easy to become, in addition, be easy to produce because the dyeing inequality in the fluffing of the draw false twisting broken yarn that causes of tension variation, finished yarn, woven or knitted fabric.On the other hand, when heat treatment time was too long, crimp percent had the tendency that too increases.Usually, for the situation of contactless heater, the scope at 0.04～0.12 second, special scope at 0.06～0.10 second is suitable.
And then the draw ratio in the draw false twisting processing is 1.4～2.4th, and is only, the low multiple district beyond in this zone, there is bound edge to take place, and produces the heat setting inequality that causes by reeling, in high multiple district, carrying out the flattening of finished yarn, and then produce the processing fluffing, is not preferred therefore.
In the method for the invention, will the false twisting that stretches and false twisting simultaneously adds man-hour count T (inferior/m) the fiber number Y (dtex) according to false twist yarn is set in (15000～35000)/Y
1/2, preferred (20000～30000)/Y
1/2Scope.When the false twisting number less than 15000/Y
1 / 2(inferior/as m) time, to be difficult to give fine and firm curling, the liquor style hardening is similar to paper when making cloth and silk, when the false twisting number greater than 35000/Y
1/2(inferior/m) time, the generation of broken yarn and fluffing increases, and is not preferred therefore.
In the method for the invention, at first, preferably for the polyester of supplying with the draw false twisting device not stretch yarn carry out interweaving between long filament by air flow in advance.This air interleaving treatment can be carried out draw false twisting processing individually, but preferably in the draw false twisting device interlacing nozzle is set as shown in Figure 1, carries out the method for air interleaving treatment before draw false twisting just.The degree that interweaves with the interleaving degree of in polyester false twist yarn, measuring be 30～80/m, more preferably 50～70/m implements like this.When interleaving degree during less than 30/m, constitute the not deterioration that becomes of the mix between the long filament of stretch yarn of polyester, therefore increasing of single thread fracture when easypro by separating in the draw false twisting operation (taking out from the raw yarn package) bad broken yarn that causes and twisting backtwisting be not preferred.When interleaving degree surpasses 80/m, constitute the obvolvent grow too between the long filament of polyester false twist yarn, yarn forms the state that solidifies, from rather than preferred.
In the method for the invention, preferably using diameter is 40～70mm, and more preferably diameter is that the false twisting disk of 45～62mm is twisted backtwisting.This false twisting disk is for example assembled 2 disks as shown in Figure 2 respectively and is used like this on the false twist unit that is disposed on 3.When the diameter of false twisting disk during less than 40mm, sharply increase at the frictionally damage that causes by the false twisting disk that comprises on the sliver of above-mentioned polymer blend, the generation of broken yarn and fluffing increases.When the diameter of false twisting disk during greater than 70mm, the twisting power that is produced by the false twisting disk reduces, have to obtain the fine and firm situation of curling more, from rather than preferred.In addition, twisting tension raises, and the generation of fluffing increases.And then the operation (lead-in wire) that mobile sliver is imported the false twisting disk becomes extremely difficult.
The move angle of the sliver by the false twisting disk (disk rotating shaft with contact the sliver angulation that moves on the disk periphery) is preferably 30～48 degree, the scopes of preferred especially 32～45 degree.Can reduce the twisting power that produces by disk thus, and can improve the yarn effect of sending, under stable status, twist backtwisting.At this moment, as mentioned above, making the disk of hypomere and the contact length of mobile sliver is 2.5～0.5mm, and this is being effective significantly reducing aspect the processing fluffing.
The antigen fibre of fiber that comprises above-mentioned polymer blend is poor, it is generally acknowledged that the low fiber of this antigen fibre can produce fluffing adding man-hour inevitably, but the method according to this invention, owing to adopted the fibre structure that sliver possessed have the antigen fibre, and the technology of processing simultaneously, therefore add in false twisting and do not produce man-hour such as section deformation, fluffing etc., false twisting processing can be at a high speed, stably carried out, high-quality false twist yarn can be prepared.
The antistatic behaviour false twist yarn of the present invention that obtains like this can be weaved under the state of non-twist, no sizing or be woven or knitting, makes good cloth and silk.At this moment, it is good to weave woven or knitting property, does not have broken yarn and comparatively level and smooth.In addition, according to above such the inventive method, can effectively, stably prepare the polyester false twist yarn of antistatic behaviour, excellent in te pins of durability.
The characteristic of＜composit false twisting finished yarn 〉
Secondly, the special composit false twisting finished yarn of antistatic behaviour of the present invention is the composit false twisting finished yarn that has composite construction as mentioned above, and described composite construction is that the skin yarn covers the structure that the periphery of the heart yarn that comprises above-mentioned antistatic polyester long filament forms basically.
Here, the skin yarn that constitutes composit false twisting finished yarn of the present invention comprises and cooperates polymethyl methacrylate based polymer and/or polystyrenic polymer to form as described above in aromatic polyester.Here, as aromatic polyester, 75 moles of % of its whole repetitives are above, special 85 moles comprise Polyethyleneglycol Terephthalate more than the %, preferably its inherent viscosity (using o-chlorphenol to measure down at 35 ℃ as solvent) is below 0.7, preferred especially 0.55～0.70.And this aromatic polyester can have identical composition with the aromatic polyester that constitutes heart yarn, also can have different compositions.
In addition, in these polyester, also can contain known additive, for example pigment, dyestuff, delustering agent, anti-fouling agent, fluorescent whitening agent, fire retardant, stabilizing agent, ultra-violet absorber, lubrication prescription.
The polymethyl methacrylate based polymer, the polystyrenic polymer that cooperate in the aromatic polyester that constitutes the skin yarn can be the amorphism polymer of atactic structure or syndiotactic structure, also can be the crystalline polymers of isotactic structure.In addition, in the scope of not damaging the object of the invention, also can contain copolymer composition.
When the molecular weight of these polymer too hour, following effect of the present invention has the tendency of reduction, therefore preferred its weight average molecular weight is more than 2000, preferred especially 5000～200,000 scope.Specifically, more preferred example can enumerate that weight average molecular weight is 8000～200,000, (with ASTM-D1238 is standard to melt index (MI) A, 230 ℃ of temperature, measure under the condition of heavy burden 3.8kgf) be that 10～30g/10 minute polymethyl methacrylate based copolymer or isotactic polystyrenic polymer or weight average molecular weight are 8000～200,000, melt index (MI) B (with ASTM-D1238 is standard, measures under the condition of 300 ℃ of temperature, heavy burden 2.16kgf) is syndiotactic polystyrene based polymer of 6～50g/10 minute etc.For these polymer, with its melting mixing and when carrying out melt spinning in above-mentioned polyester, therefore the excellent in stability of its heat endurance and dispersity is preferred.
Infer since by above-mentioned polymethyl methacrylate based polymer and/or polystyrenic polymer in polyester mixing and form the cause of fine protuberance on the surface of this fiber, found that the fibre-fibre friction resistance to descend and become and be easy to slide, can produce following such effect thus, promptly, can realize having the woven or knitted fabric of the liquor style of softness and smooth surface sense of touch, the gloss when dyeing on the other hand can maintain level equal when not adding.In order to produce above-mentioned effect, when being benchmark with the weight polyester, the content of above-mentioned polymer needs 0.5～3.0 weight %, preferred 1.0～2.0 weight % to close quantifier.When content during less than 0.5 weight %, the friction between fiberoptic fiber descends insufficient, and therefore the liquor style hardening of gained cloth and silk is not preferred.
On the other hand, when above-mentioned content during greater than 3.0 weight %, the effect that not only above-mentioned polymer adds is saturated, and the stability of the spinning of fiber, stretching process reduces, and broken yarn increases, and is not preferred therefore.And, also polymethyl methacrylate based polymer and polystyrenic polymer can be share, the weight % that this moment, both added up to is in the scope of above-mentioned content.
In the present invention, by the skin yarn is made this composition, can also reach the above-mentioned effects such as sense of touch of improving the composite yarn surface, the most important thing is when in the skin yarn, mixing polymethyl methacrylate based polymer or polystyrenic polymer, owing to compare with the identical unmixed yarn that spins speed, its percentage elongation uprises, so being carried out composit false twisting, they add man-hour, can obtain this mixed yarn and be easy to be engaged in the skin zone of composite yarn, the antistatic sliver as composite object is easy to be engaged in effect such in the core on the contrary.
And, under the scope that does not harm the object of the invention, in the above-mentioned polymer blend that forms the skin yarn, also can cooperate known additive as required, for example pigment, dyestuff, delustering agent, anti-fouling agent, fluorescent whitening agent, fire retardant, stabilizing agent, ultra-violet absorber, lubrication prescription etc.
In composit false twisting finished yarn of the present invention, need the yarn length of the sliver group B of the sliver group A of heart yarn and skin yarn to have difference, especially, the length of sliver group B is preferably long by 10～20% than sliver group A, more preferably long 12～18% scope.At this moment, form sliver group A and mainly be engaged in the core of composit false twisting finished yarn, sliver group B mainly is engaged in the core skin structure in the skin zone.By forming the long difference of this yarn, can stably encase heart yarn along the yarn length direction with antistatic behaviour with the skin yarn, formation can be than the high maintenance antistatic behaviour, and the good result of washing resistance.In addition, more very thin skin yarn can make finished yarn and the soft liquor style of woven or knitted fabric performance that comprises it.In addition, the operability in the woven or knitted fabric operation improves, and can obtain high-quality woven or knitted fabric.
In the present invention, the crimp percent of the above-mentioned the sort of composit false twisting finished yarn that is made of sliver group A and sliver group B need have curling of 2～8% scope, special 3～7% scope.
By making crimp percent, can obtain the woven or knitted fabric of soft liquor style excellence in this scope.With respect to this, when crimp percent less than 2.0% the time, too increase in the space between the sliver when forming woven or knitted fabric, is easy to enter the dyestuff more than the requirement when dyeing, it is uneven to be easy to generate dyeing, is not preferred therefore.On the other hand, when greater than 8.0% the time, gained grandrelle yarn woven or knitted surfaces forms the tone of white, and the quality of woven or knitted fabric shows as loose sense, is not preferred therefore.
And, from the sliver group A that constitutes the composit false twisting finished yarn or sliver group B, take out sliver separately, crimp percent when measuring separately respectively can be identical mutually, also can be different, when the crimp percent of sliver group B is big, be easy to this sliver B mainly is engaged in the skin zone of composit false twisting finished yarn, therefore making woven or during knitted fabric, can improve the liquor style of softness and level and smooth surface touch, be preferred therefore.
For composit false twisting finished yarn of the present invention, and then its charged friction is pressed to below the 2000V, preferably in the scope of 500V～1500V.Charged friction press be with the composit false twisting finished yarn carry out that tube is woven or knitting, after the dyeing, damping, utilize JIS L 1094 charging property test method B methods (frictional electrification pressure determination method) to measure the getable value of antistatic behaviour, when frictional electrification is pressed to (preferably below the 1500V) below about 2000V, can be evaluated as and have antistatic effect.
Composit false twisting finished yarn of the present invention is easy to when making woven or knitted fabric fine Auto-regulating System of Density of Heavy Medium to suitable scope, so its total fiber number is that the scope of 100～300dtex (dtex) is suitable, the scope of preferred 130～270dtex.When total fiber number during less than 100dtex, a little less than the TENSILE STRENGTH of woven or knitted fabric, and be difficult to obtain fully intensive woven or knitted fabric, not preferred therefore.On the other hand, when greater than 300dtex, because weight per unit area woven or knitted fabric too becomes greatly, so be not preferred as woven or knitting usefulness.And, consider from angle with finer property, the total fiber number of preferred sliver group A and sliver group B than with the former/latter counts 40/60～60/40, preferred especially 45/55～55/45 scope.
On the other hand, the filament fiber number of sliver group A and sliver group B can be identical, also can be different, and its average single fiber fiber number need be 1.0～5.0dtex, the scope of preferred 1.2～4.0dtex.When average filament fiber number during less than 1.0dtex, sliver group A carried out with mixing too of sliver group B, thereby was difficult to show the woven or knitted surfaces of gained, was not preferred therefore.On the other hand, when average single fiber fiber number during greater than 5.0dtex, thick and stiffization of liquor style of the woven or knitted fabric of gained brought bad sense of touch to the surface, is not preferred therefore.And, when the filament fiber number of heart yarn and skin yarn B not simultaneously, for the easier sliver group that is engaged in the core of composit false twisting finished yarn, the sliver group that preferably its filament fiber number is big.But if too big, then liquor style is easy to become thick and stiff, and therefore preferred filament fiber number is below the 5.5dtex.
The preparation method of＜composit false twisting finished yarn 〉
More than the of the present invention woven or knitted fabric of explanation can for example prepare by following method with polyester composit false twisting finished yarn.Promptly, in that being carried out draw false twisting, polyester multifilament adds man-hour, use polyester not stretch yarn (A ') and polyester not stretch yarn (B ') as the polyester raw yarn of processing usefulness, with they plying, satisfy at the same time and stretch under the condition of following (1)～(4) and false twisting is simultaneously processed and prepared, described polyester not stretch yarn (A ') cooperates above-mentioned polyoxyalkylene glycol (a) and forms with ionic antistatic additive (b), described polyester not stretch yarn (B ') mixes above-mentioned polymethyl methacrylate based polymer and/or polystyrenic polymer.
(1) in the line space gas interleaving treatment of will false twisting advancing, form more than 30/entanglement of m,
(2) the false twisting instrument uses 3 friction circle dish-types, the material of disk that wherein is positioned at the hypomere at backtwisting position is pottery, the contact length of this disk and mobile sliver is 2.5～0.5mm, and the diameter of this disk be adjacent its top disk diameter 90～98%
(3) false twisting processing temperature is 170 ℃～300 ℃ a temperature,
(4) with respect to the fiber number (Y dtex) of false twist yarn, it is (inferior/as m) to be 15000/Y that T is counted in false twisting
1/2≤ T≤35000/Y
1/2
Here, the low elongation side that forms heart yarn not the high elongation rate side of stretch yarn (A ') and formation skin yarn do not have the elongation rate variance between the stretch yarn (B '), when the percentage elongation of stretch yarn B ' not be 70～150%, during especially in the big like this scope of 90～130% scopes, for gained composit false twisting finished yarn, sliver group B mainly is engaged in its skin zone, therefore gained liquor style woven or knitted fabric is more soft and have elasticity, from but preferred.And, when the elongation rate variance greater than 150% the time, liquor style presents loose sense, and is easy to produce tension variation in the draw false twisting manufacturing procedure, is therefore increased by its broken yarn frequency that causes, and can not stably process.
In addition, the low elongation side is stretch yarn (A ') and high elongation rate side after stretch yarn (B ') can not spin respectively and reel not, they are closed yarn supply with draw false twisting processing, also each polymer can be discharged from the fusion simultaneously of different spinning spinning heads, after cooling each sliver group being closed yarn also reels, the processing of supply draw false twisting, in the latter's method, when being 2500～4000m/ branch at spinning speed, when carrying out melt spinning under the scope that special 3000～3500m/ divides, for the polyester that contains 0.5～3.0 weight % polymethyl methacrylate based polymer and/or polystyrenic polymer, the not stretch yarn that gets with polyester is carried out melt spinning with identical speed is compared, can be easily and obtain 70～150% efficiently, therefore special 90～130% big like this percentage elongations is preferred.
Usually, the sliver that contains antistatic additive is easy to fibrillation, in false twisting processing, be easy to produce fluffing, in the present invention, antistatic sliver is engaged in the core, and encase heart yarn and reduce the distortion that adds man-hour with skin zone's sliver, be difficult to occur fluffing man-hour basically adding thus, even therefore in draw false twisting processing, also almost can't see the generation of fluffing.
In the method for the invention, at first need for as described above with the low elongation side not stretch yarn (A ') and high elongation rate side not stretch yarn (B ') close yarn or spinning and mix the not stretching sliver that fibre forms and carry out the air interleaving treatment.
The air interleaving treatment also can be carried out with other operations different with draw false twisting processing, but preferably as shown in Figure 1, interlacing nozzle (4) is set in the draw false twisting processing unit (plant), and just implements this processing in the draw false twisting first being processed.Can suppress to produce the influence that brings to operability thus by the burl that causes of elongation rate variance.
And then, interlacing nozzle by utilizing other (not having diagram) is implemented air to the sliver of heat setting under the false twisting and is interweaved giving, can make fully and mix the fibre homogenising that interweaves, and evenly encase heart yarn at yarn length direction epithelium yarn, by above-mentioned effect, can have the antistatic property of durability and can show feeling of high class.
The degree that interweaves when the air that utilizes interlacing nozzle to carry out too after a little while, low elongation side sliver group A separates with high elongation rate side sliver group B in draw false twisting processing, it is inhomogeneous that fabric face when making woven or knitted fabric is easy to become, particularly the elongation rate variance between stretch yarn A ' and the B ' is not that situation more than 30% increases, therefore preferably make the interleaving degree of in gained composit false twisting finished yarn, measuring be 30/more than the m, special 40/implement like this more than the m.On the other hand, when the interleaving degree of being given by interlacing nozzle was too big, the obvolvent between the single thread too strengthened, and it is thick and stiff that the liquor style when making woven or knitted fabric is easy to become, therefore preferred interleaving degree be 80/below the m.
Then, the not stretch yarn of implementing interleaving treatment for example hangs on as shown in Figure 1 the draw false twisting processing machine with 2 segmentation heaters and makes and have curling polyester false twist yarn.In the example of Fig. 1, as described above the not stretch yarn (1) that 2 kinds of polymer blends spin simultaneously, doubling forms is carried out the air interleaving treatment by the interlacing nozzle (4) that is arranged between 2 pairs of feed rollers (3,3 ').Here, the not stretch yarn of having given the interlacing degree of regulation stretches between feed roller (3 ') and the 1st outlet roller (8) on one side, one side by twisting with the friction of the disk of false twisting instrument (7)., under the twisting state, utilize the 1st section heater (5) to heat-treat therebetween, and, carry out backtwisting by false twisting instrument (7) with after coldplate (6) cooling.And then, mobile sliver carries out heat treatment again with the 2nd section heater (9) that is arranged between the 1st outlet roller (8) and the 2nd outlet roller (10) as required, and then for heat setting false twisting after sliver implement air and interweave, use batching licker-in (11) to be wound into bobbin shape package (12) then, thereby be made as the antistatic polyester composit false twisting finished yarn of purpose.
At this moment, consider and under high speed, carry out draw false twisting processing that the 1st section heater (5) and the 2nd section heater (9) all are preferably contactless.Especially, the 2nd section heater (9) mostly is SW-OFF (not using this heater), but according to needs such as the desired liquor styles of finished yarn, also can use.
In the method for the invention, importantly false twisting instrument (7) is the instrument of 3 friction circle dish-types as shown in Figure 2, the disk material that is positioned at the hypomere at its backtwisting position is pottery, and the contact length that makes mobile sliver and this disk is 2.5～0.5mm, so the diameter of this disk be adjacent its upper reaches disk diameter 90～98%.
Promptly, false twisting instrument (7) shown in Figure 2 is that 3 friction circle dish-types that 2 false twisting disks (13) form are installed respectively on 3 rotating shafts (15), each rotating shaft (15) rotates with fixing speed by the synchronous belt (16) that drives with driving belt (17), thereby makes each false twisting disk (13) rotation.In the method for the invention, the disk of the hypomere that is arranged in the backtwisting position at least in the false twisting disk (13) (the example of Fig. 2 be mounted in the left side spin rotating shaft below disk) be the pottery system, and the diameter of this disk be adjacent its upstream side disk (in the example of Fig. 2, be mounted in central rotating shaft below disk) diameter 90～98%.And should pottery rounding dish and the contact length of mobile sliver be 2.5～0.5mm.
At this moment, consider that the disk material of preferably hypomere is a pottery from anti abrasive angle.People's the research according to the present invention, as can be known in composit false twisting processing of the present invention, by the contact length that makes mobile sliver and this disk is 2.5～0.5mm, can do one's utmost to reduce and finish in twisting, contact area when the sliver of rolled state enters last backtwisting position, and reduce resistance, consequently significantly reduced fluffing, the diameter that makes this disk then is 90～98% a scope of the disk diameter of adjacent its top, the Resistance Value when this makes guide shift to next step (being heat setting specifically) for minimizing and can level and smooth mobile this respect effective etc.Confirming that wherein by the contact length that makes mobile sliver and above-mentioned disk be 2.5～0.5mm, is effective especially for remarkable minimizing processing fluffing.
In the method for the invention, by the combination of above-mentioned each condition, can significantly reduce the generation of processing fluffing.Yet, in the time of outside this scope, producing the processing fluffing, the quality that forms weavability for product on the market, easy zbility, fabric product causes dysgenic major reason.
False twisting processing temperature of the present invention need be at 170～300 ℃.When this temperature during less than 170 ℃, crimp property is low, and liquor style is hard, when greater than 300 ℃, extremely carries out the flattening of finished yarn, produces the processing fluffing, is not preferred therefore.The device that has a contactless heater when use is during as false twist processing machine, and the design temperature that preferably makes the 1st section contactless heater is 170～300 ℃ and heat-treats like this.And, here so-called suitable heter temperature is set according to commercially available false twist processing machine (Supreme Being people's making mechanism 216 hammers are built HTS-15V), suppose its be contactless 1.0～1.5m length, yarn speed for the 800m/ branch～etc. the false twist processing machine of type, therefore, for the situation of using special heater or processing with ultraspeed etc., should suitably adjust design temperature certainly.
Here, the 1st heater in twisting zone is used to improve the do not stretch draftability and the false twisting processability (twisting) of sliver, is during less than 170 ℃ temperature in its temperature for the situation of noncontact heater, the reduction of twisting property, can not give as the curling of the object of the invention, the liquor style when making woven or knitted fabric is similar to paper.In addition, draw false twisting adds the broken yarn in man-hour and the generation of fluffing increases, and therefore the dyeing inequality when also being easy to take place to curl uneven or dyeing is not preferred.On the other hand, when surpassing 300 ℃, add at draw false twisting and to be easy to produce the single thread fracture man-hour, (B ') is easy to produce the single thread fracture for the not stretching sliver of high elongation rate side especially, gained polyester composit false twisting finished yarn has more fluffing, is not preferred therefore.And according to the type of draw false twisting processing machine, the 1st section heater has first half and the latter half of situation of being divided into, in the method for the invention, as long as the first half of the 1st section heater and latter half ofly set same temperature for.
And, the heat treatment time of sliver can be according to the suitably decision such as kind, its length and its temperature of heater in the 1st section heater, but work as heat treatment time too in short-term, it is insufficient that crimp percent is easy to become, in addition, be easy to produce because the dyeing inequality in the fluffing of the draw false twisting broken yarn that causes of tension variation, false twist yarn, woven or knitted fabric, on the other hand, when too long, crimp percent has the tendency that too increases.Therefore when heat-treating with contactless heater, this heat treatment time was 0.04～0.12 second scope usually, and special scope at 0.06～0.10 second is suitable.
And then, for the draw ratio that adds man-hour, 1.4 the～1.7th, only zone, in this zone beyond the time, for low multiple side, there is bound edge to take place, and produce the heat setting inequality that causes by reeling, for high multiple side, carry out the flattening of finished yarn, and produce the processing fluffing, not preferred therefore.
When the fiber number note of composit false twisting finished yarn was made Y (dtex), the false twisting number was set in [(15000～35000)/Y
1/2] inferior/m, more preferably [(20000～30000)/Y
1/2] scope of inferior/m.When false twisting number during less than 15000/Y1/2 time/m, be difficult to give fine and firm curling, the hardening of gained cloth and silk liquor style is similar to paper.When the false twisting number greater than 35000/Y
1/2(inferior/m) time, the generation of broken yarn and fluffing increases.
In the present invention, at first need for supply with the draw false twisting device, close yarn or spinning mix polyester that fibre forms not stretch yarn carry out air in advance and interweave.Air interweaves and can carry out draw false twisting individually and handle, but preferably in the draw false twisting device interlacing nozzle is set as shown in Figure 1, carries out the method for air interleaving treatment before will draw false twisting.The degree that air interweaves with the interleaving degree of in polyester false twist yarn, measuring be 30～80/m, more preferably 50～70/m implements like this.When interleaving degree during less than 30/m, constitute not deteriorations that become of the mixed state between the sliver of stretch yarn of polyester, the generation of the single thread fracture in the draw false twisting operation when separating broken yarn that Shu Buliang causes and twisting backtwisting etc. increases, so is not preferred.On the other hand, when interleaving degree surpassed 80/m, the obvolvent that constitutes between the single thread of polyester false twist yarn too strengthened, and yarn presents the state of curing, from rather than preferred.
The disk size of false twisting instrument is not particularly limited, and preferred diameter is the disk of 40～70mm, and more preferably diameter is the disk of 45～62mm.For example respectively assembling 2 disks as shown in Figure 2 on the false twist unit that is disposed on 3 uses like this.When disk diameter during less than 40mm, the frictionally damage that is caused by disk of sliver group A ' increases, and the generation of broken yarn and fluffing is easy to increase.On the other hand, when greater than 70mm, the twisting power that is produced by disk reduces, and is difficult to give fully and curls.
The move angle of the sliver by this disk (disk rotating shaft with contact the sliver angulation that moves on the disk periphery) is preferably 30～48 degree, the scopes of preferred especially 32～45 degree.Can reduce the twisting power that produces by disk thus, and can improve the yarn effect of sending, under stable status, twist backtwisting.
Usually, the sliver that contains antistatic additive is easy to fibrillation, in false twisting processing, be easy to produce fluffing, in the present invention, antistatic sliver be engaged in the core, and encase heart yarn and reduce the distortion that adds man-hour with skin zone's sliver, be difficult to occur fluffing man-hour adding thus, and select the false twisting processing conditions as described above, so both cooperatively interact, the few generation fluffed, and obtains very good composit false twisting finished yarn.
The composit false twisting finished yarn of the present invention that obtains so for example can be under the state of non-twist, no sizing be made fabric by water jet looms etc., and this moment can be good in weavability, does not also have under the situation of broken yarn etc. and successfully weaves.The cloth and silk that comprises polyester composit false twisting finished yarn of the present invention has good antistatic behaviour, in addition, even aspect the sense evaluation, very satisfied thickness is arranged also, and have feeling of high class, form soft and present the cloth and silk of the like staple fiber yam presentation quality style of good expansion sense.
