Detailed Description Of The Invention
Polyester capillaries of the present invention is in fact the composite filament that is formed by PTT.
Among the present invention, consist of the polyester of polyester capillaries, its Component units at least 90mol% is take terephthalic acid (TPA) as main acid constituents, the PTT (PTT made in following brief note) that the diol component take 1,3-PD as the master makes. Here, also can contain 10mol%, preferably contain the copolymer composition that other following ester bond of 6mol% forms. But can enumerate such as glycols such as omega-dicarboxylic acids, ethylene glycol, diethylene glycol (DEG), dipropylene glycol, butanediol, neopentyl glycol, cyclohexanedimethanol, polyethylene glycol, polypropylene glycol such as M-phthalic acid, succinic acid, cyclohexane cyclohexanedimethanodibasic, adipic acid, cannabinoid acid, decanedioic acid, 5-sodium sulfonate M-phthalic acids as the compound of copolymerization, but, be not limited to these. In addition, also can add as required TITANIUM DIOXIDE DELUSTRANT, lubricant silica and/or alumina particulate, antioxidant ヒ Application ダ one De phenol derivatives, coloring pigment etc.
In addition, the intensity of polyester capillaries of the present invention is very important more than the 3cN/dtex. If intensity below 3cN/dtex, then will cause the phenomenons such as fluffing, broken string in the senior manufacturing procedures such as the system of knitting, the goods tearing strength that makes simultaneously is low.
Elongation at break with knit the frequency relation of being inversely proportional to that fluffing occurs when processed, elongation at break more can satisfy the intensity of practicality, then more can suppress the generation of fluffiness. For this reason, residual percentage elongation be more than 40% for good, be preferably more than 45%.
Polyester Filament of the present invention, Young's modulus are below the 25cN/dtex, and percentage elongation is that the minimum of a value of 3～10% o'clock differential Young's modulus is very important below the 10cN/dtex.These characteristics are all closely related with tensile properties, the resilience of elasticity cloth and silk, and in order to satisfy the gentle elasticity of requirement of the present invention, above-mentioned no matter which kind of characteristic is got low value for well.That is, owing to satisfied above-mentioned characteristic fully, so when making cloth and silk, the initial stage stretches easy (low Young's modulus).In addition, owing to can unhinderedly stretch (low differential Young's modulus) in the scope of 3～10% percentage elongation of in actual use stretching resilience, so can make gentle elasticity cloth and silk comfortable and easy to wear.
The flexural rigidity of Young's modulus and cloth and silk is also proportional, and Young's modulus is low more, and soft hand feeling is just arranged more.For this reason, Young's modulus with below the 22cN/dtex for well, serving as better below the 20cN/dtex.
Equally, percentage elongation be 3～10% o'clock the differential Young's modulus minimum of a value with below the 8cN/dtex for good, with below the 5cN/dtex for better.
It is more than 90% that Polyester Filament of the present invention extends 10% later rebound degree.If rebound degree less than 90%, then after the elongation, the part of residual part plastic deformation down can produce the shortcoming that is called " loose twist ", therefore, and the decline of the grade of fabric.The rebound degree of elongation after 10% more than 95% for well, then better more than 98%.
The silk resilience that is formed by PTT well mainly results from its molecular structure.In the crystalline texture of PTT, the methylene chain of alkylene glycol part is a domination left and right sides structure arranged, because phenyl ring overlaps each other and interact to reduce and density reduces, flexible raising, so, can make strand extend easily, bounce back by the turning effort of the methylene chain of aforementioned alkylene glycol part.
In addition, in the inventor's experiment as can be known: degree of crystallinity is high more, and resilience is high more.Therefore, degree of crystallinity with more than 30% for well, better more than 35%.Here, the mensuration of degree of crystallinity is pressed the density tapering pipe method of JISL1013 (chemical fiber filament test method) 7.14.2, is tried to achieve by density.
Polyester Filament boiling water shrinkage of the present invention is 3～15%, and the maximum of shrinkage stress is below the 0.3cN/dtex, and the temperature when showing the shrinkage stress maximum is for good more than 120 ℃.
Boiling water shrinkage is design one of most important factor during cloth and silk, and boiling water shrinkage is set in 3% when above, and the shape stability in senior operation is relatively good, is set at 15% when following, and can make does not have cloth and silk coarse hard sense, soft.Equally, if thermal shrinkage stress is too high, the superfluous contraction then arranged, just the feel of coarse hard sense is arranged.Therefore, for obtain not have coarse hard sense, soft hand feeling, the maximum of shrinkage stress is that 0.3cN/dtex is following for good, with 0.15～0.25cN/dtex for better.In addition, in order to formalize easily and to improve senior processing such as bulk, the temperature when showing the shrinkage stress maximum to be being good more than 120 ℃, with more than 130 ℃ for better.
Polyester Filament of the present invention, the continuous shrinkage factor CV% on the draw direction of silk with below 5% for well.Shrinkage factor CV% is one of index of reflection silk homogenieity disadvantage on draw direction continuously, and this value is more little, quality is high more.In order to make high-quality cloth and silk, CV% with below 5% for well, serving as better below 4%.
Polyester Filament of the present invention is carried out interleaving treatment, and the CF value is good in 1～30 scope.The CF value is fixed to more than 1, when carrying out throwing, silk processing and knitting system, can suppress the fracture of monofilament.In addition, make the monofilament bar, mix when fine as the combined yarn that the shrinkage difference will be arranged, good in order to make animal migration, with CF value calmly to below 30 for well.It is then better that the CF value is controlled at 5～25 scope.
Constitute the section configuration of Polyester Filament fiber of the present invention, no matter be garden section, triangular cross-section, leafy shape section, flat partially section, X type section or other well-known section all can, without any restriction, can do suitable selection as required.
Flexibility when making fabric in order to improve, filament fiber number are that 5dtex is following for good, with below the 3dtex for better.
Polyester Filament of the present invention has very confidential relation between twist multiplier and the elasticity, if when twist multiplier surpasses a certain value, then elasticity has the tendency that is increased sharply.In fact, be about 5000 the fabric made of silk with twist multiplier, rebound degree is about 5%, and still, twist multiplier is 10000 o'clock, and rebound degree is about 15%, and twist multiplier is 14000 o'clock, rebound degree then brings up to about 30%.Therefore, though even the Polyester Filament no twist that makes among the present invention also can use,, it is then better to be by twist multiplier that high twist yarn is made in 10000～20000 middle twisted filament.
Twist multiplier is represented with following formula:
Twist multiplier K=T * U
0.5
T: the twisting count of every 1m filament length.D: the fiber number of strand
Here, the twisting count T of so-called every 1m filament length is meant with electronic inspection twister 90 * 10
-3Backtwisting under the loading of cN/dtex, the ratio value representation of separating filament length behind twisting count and the backtwisting when using up complete solution and twisting with the fingers.
Cloth and silk form of the present invention has fabric, compiles thing, nonwoven fabric and padded coaming etc., can do suitable selection according to the purposes difference, can be suitable for to make men's shirt, blouse, pants, suit, Block Le ゾ Application etc.
Enumerate a Polyester Filament preparation method's of the present invention example below.
Preparation method as the main raw material PTT of Polyester Filament of the present invention can directly use well-known method.Stringiness when improving spinning makes the silk with practical intensity, and the inherent viscosity of used PTT [η] is very important more than 0.7, is preferably more than 0.8.
In addition, Polyester Filament of the present invention, both direct spinning stretching carried out so-called continuous polymerization spinning behind the polymerizable, and also can cutting into slices, the back is dry, spin-drawing.
During melt spinning, for the spray silk that makes the nozzle place stable, spinning temperature than the fusing point of PTT high 10～60 ℃ for good, than fusing point high 20～50 ℃ better.In order to suppress separating out of oligomer in the spinning, improve spinnability, also can cartridge heater, suction device be set as required, for preventing the polymer oxidative degradation or preventing that nozzle from polluting the also generator of inert gases such as available air, water vapour, nitrogen at 2～20cm place under the nozzle.
In addition, when preparing Polyester Filament of the present invention, the most important thing is spinning after, the drawing process of the direct fabrics that stretch is immediately adopted in then not rolling.
By the undrawn yarn that PTT forms, as previously mentioned, its internal structure just begins to change after spinning, produces so-called lock seam phenomenon, and this becomes the reason that causes tow ectonexine poor properties.For this reason, in order to suppress the generation of this lock seam phenomenon, the inventor studies, know, after dividing above spinning speed to stretch with 2000m/, then not rolling and after the continuously elongated heat treatment, the heat treatment that relaxes continuously of the relaxation rate with 5～20% is effective.Adopt this method, can improve edge-curl phenomenon greatly, the difference of the inside and outside layer of tow is minimum, makes high-quality silk.In addition, also find the heat treatment that relaxes under high relaxation rate, then the Young's modulus in stretching resilience field is low, can make the gentle elastic yarn of easy stretching.
The strand inhomogeneities is little in order to make, the homogeneous silk of the shortcoming such as inhomogeneous that is difficult to occur to dye, and it is very important more than dividing that spinning speed is controlled at 2000m/.Improve spinning speed, also improved spinning tension, because of being difficult to be subjected to the influence of external interference, so the refinement operation is stable.For this reason, divide above speed spinning then better with 3000m/.In order further to guarantee stable stringiness, preferably spinning speed is controlled at below the 6000m/ branch.
Stretching ratio is set in and makes residual percentage elongation is for well more than 40%.
In order to make target polyesters silk of the present invention, it is 6～20% very important that the relaxation rate during with the lax heat treatment after stretching is controlled at.After the stretching, carry out the lax heat treatment more than 6%,,, can suppress edge-curl phenomenon and take place so the delay slack of permanent set diminishes because the deformation of fibrous inside can relax rapidly.As previously mentioned,, in the elongation range (percentage elongation is below 10%) of practicality, stretch easily, also can give excellent gentle elasticity owing to passed through lax heat treatment.Be more preferably relaxation rate more than 8%.On the other hand, in order to ensure the stability of tow operation in the silk producing procedures, relaxation rate is controlled at 20% below to well, and being controlled at below 18% is better.
Here, with Fig. 1 and Fig. 2 the heat-treating methods that relaxes is described.
Fig. 1 is in the lax heat treatment process, adopts the schematic diagram of cold roller method.By the tow of spinning-nozzle 1 ejection, after ventilator 2 coolings, refuel convergence in the guide groove 3, give finish after, after 4 tractions of the 1st hot-rolling, heating up, between the 1st hot-rolling 4 and the 2nd hot-rolling 5, stretch, HEAT SETTING.After the drawn operation, utilize the heat of the 2nd hot-rolling 5 again, the heat treatment that relaxes between the 2nd hot-rolling 5 and cold roller 6 is by winder 8 rollings.For the heat treatment that more effectively relaxes, between the 2nd hot-rolling 5 and cold roller 6, adopt with hot-air and/or steam as the annealing device of thermal medium or the 3rd hot-rolling is set, carrying out the second step relaxation processes also is the effective ways that reach the object of the invention.
Fig. 2 is the schematic diagram that adopts the method for the spinnerets that interweaves in the lax heat treatment process, and the spinnerets 7 that interweaves plays a part control tow cooling device and tension gradient.That is, owing to, the tow tension before interweaving is descended, so the shrinkage stress that utilization is produced by the effect of the heat of second hot-rolling 5 can and interweave at second hot-rolling 5 and carry out hot relaxation processes between the spinnerets 7 through interleaving treatment.At this moment, relaxation rate can be controlled by the interweave air pressure of spinnerets action of change.In addition, at the 2nd hot-rolling 5 with interweave between the spinnerets 7 also and can carry out the second step relaxation processes by adopting with hot-air and/or steam as the annealing device of thermal medium or the 3rd hot-rolling is set.
These methods are all controlled relaxation rate easily, are the desirable methods of preparation Polyester Filament of the present invention.
In addition, double as stretches, HEAT SETTING reaches lax heat treated warm-up mill (the 2nd hot-rolling in Fig. 1, Fig. 2 example), and the most handy surface roughness is the wrinkle roller of 1.5S～8S.Surface roughness is the fragmentation value of the maximum height (Rmax) put down in writing among the JIS B0601, and in fact 1.5S～8S is equivalent to the fragmentation value of 1.6S, 3.2S, 6.3S.Its maximum height surpasses 0.8 μ m, corresponding with below the 6.3 μ m.This Roughness Surface on Control more than 1.5S, because the coefficient of friction between tow and the roller descends significantly, is had moderately and skids, so even under high relaxation rate, tow can warp, stably throwing on warm-up mill yet.When surface roughness is high, though tow can stably move in lax operation,, if surpass 8S, because tow surface excessive friction, so cause intensity decreases.The optimal surface roughness of warm-up mill is 3.2S～6.3S (Rmax:1.7～6.3 μ m).The mensuration of surface roughness is pressed the regulation of JIS B 0601, measures with the ホ Application メ Le テ ス -T1000 type instrument of ホ Application メ Le corporate system and asks for maximum height Rmax.
In order there not to be fracture of wire, stably carry out throwing, draft temperature (temperature of the 1st hot-rolling) is advisable for high 10～50 ℃ to be controlled at than the glass transition temperature of PTT, and it is then better to stretch under the temperature of glass transition temperature+20～40 ℃.HEAT SETTING and lax heat treated temperature (the 2nd heat roller temperature) are though can be in 90～180 ℃ temperature range, set according to desirable percent thermal shrinkage, but, in order not have uneven silk and to make the residual deformation that causes by stretching lax, be controlled in 105～180 ℃ of scopes temperature then better.
Spinning oil will contain flatting agent, emulsifying agent and antistatic agent etc.Specifically can enumerate mineral oil such as atoleine, octyl palmitate, laurel oleate, fatty acid esters such as stearic acid isotridecyl ester, dioleyl adipate, binary acid dibasic esters such as di-n-octyl sebacate, trimethylolpropane trilaurate, coconut wet goods polyol ester, aliphatic such as dilauryl thiodipropionate contain thioesters, polyoxyethylene oleyl ether, Emulsifier EL-60 base ether, the polyoxyethylene nonylplenyl ether, non-ionic surface active agents such as trimethylolpropane trilaurate, alkylsulfonate, anion surfactants such as the slaine of alkylphosphonic etc. or amine salt, Sodium docusate salt, oxolane/ethylene oxide copolymers such as sodium alkanesulfonate salt, expoxy propane/ethylene oxide copolymer etc., be throwing, warping, knit in each operation of system, when particularly knitting system, for improving reed, the trafficability characteristic of harness cord and the prescription that adopts.As required, also can with rust inhibitor, antiseptic, antioxidant, bleeding agent, surface tension reducer, commutation viscosity reducers, anti-abrasion agent, other modifier etc. and use.
The adhesion amount of finish for tow, is controlled at 0.3～1.2 weight %, and this is being favourable aspect senior operation trafficability characteristic.
