Abstract
Provided are antistatic polyester ultrafine fibers of superior durability. Also provided is a method for producing the same. Antistatic polyester ultrafine fibers are endowed with a variety of properties, such as UV-blocking activity, cation dyeability, flame retardence, spun-like bulkiness, soft surface texture and spring, repellency, dry texture, natural texture and spunized appearance, wool-like texture, wrinkle resistance, water absorbency and fast dryability, by introduction of a third component to the antistatic polyester ultrafine fibers, the formation of composite fibers with other fibers, modification of the cross-sectional shape, and the like.
Description
Technical field
The present invention relates to the polyester superfine fibre with antistatic behaviour and the manufacture method thereof of excellent in te pins of durability.In more detail, relate to can be by the 3rd composition importing or with compoundization of other fiber, the change of cross sectional shape etc. give the flexible touch on fluffy sense, surface of ultraviolet screening effect, cation dyeable, anti-flammability, spinning sample and elasticity, resilience, dry feeling, naturally sense and Si Bennaizi Texturized (ス パ Na イ ズ) outward appearance, imitate the antistatic polyester superfine fibre and the manufacture method thereof of various functions such as wool sense of touch, fold are restorative, water-absorbing fast-drying.
Background technology
In the past, carried out giving hydrophily and the trial that makes it to show antistatic behaviour, proposed to have a large amount of motions up to now polyester.Known for example have a method (Japanese Patent Publication 39-5214 communique) that cooperates poly (oxyalkylene) base system polyether compound in polyester, method (the Japanese Patent Publication 44-31828 communique that in polyester, cooperates the ionic compound of the poly (oxyalkylene) base system polyether compound of non-intermiscibility basically and organic-inorganic, Japanese Patent Publication 60-11944 communique, Japanese kokai publication sho 53-80497 communique, Japanese kokai publication sho 53-149247 communique, Japanese kokai publication sho 60-39413 communique, Japanese kokai publication hei 3-139556 communique etc.).In these methods,, be truth but the inequality of the inequality that ultra fine yarn SMIS/sheath forms, single thread fiber number causes the situation with antistatic behaviour if the single thread fiber number greater than 1.6 dtex, then has antistatic behaviour.
Yet in recent years, requirement for the quality (texture) of woven and knit goods (woven and knitted fabrics), feel, outward appearance etc. improves day by day, use ultra-fine drawn polyester yarn in the past and carry out knitting or woven (knitting or weaving) though the cloth and silk of gained can obtain soft quality, performances such as heat insulating ability, suction, hygroscopicity also improve, but the what is called that can suppress Pi crack static has the cloth and silk of antistatic behaviour and does not almost completely have, so and insufficient.Especially, motion dress material, uniform etc. cover ultraviolet ray and suppress on the purposes of static without, and the cloth and silk that can not get having antistatic behaviour is a present situation.
In addition, polyester be cannot say for sure also that dyeability is good, is had the shortcoming of the vivid degree variation of product dyed thereby with fiber as dress material.At present, in order to remedy such shortcoming, be well known that copolymerization with M-phthalic acid 5-sodium sulfonate etc. be that the composition that contains azochlorosulfonate acid alkali of representative obtains, to basic-dyeable fibre be stainability polyester (below, abbreviate cation dyeable polyester as), the fiber that comprises this polyester is used in the dress material field.
Yet these cationic dyeable polyester fibers the time are difficult to take place fusion than common polyester fiber melt viscosity height, burning and drop, so have the shortcoming of easy fire spreading, the problem that existence requires the use in the field of anti-flammability to be restricted.
In order to solve such problem, also copolymerization proposed except that the composition that contains azochlorosulfonate acid alkali there has been to propose in the polyester of specific phosphorous dicarboxyl oxygen compound, the TOHKEMY 2005-273043 communique polyester that copolymerization has specific organic phosphorus compound in the Japanese kokai publication hei 7-109621 communique.
Yet, in this method, be the acid catalyst effect that utilizes phosphorus compound, the generation of diethylene glycol (DEG) is promoted in polymerization process, because diethylene glycol (DEG) content uprises, thereby has the problem of stringiness, light resistance variation.
Further, for polyester fiber, polyester long fiber particularly, as the quality of giving like staple fiber yam as the high wool or the method for bulkiness, Japanese Patent Publication 60-11130 communique for example, Japanese Patent Publication 61-19733 communique, Japanese kokai publication hei 8-13275 communique, shown in the TOHKEMY 2006-169697 communique etc., proposed to utilize and made up the long stapled like staple fiber yam sample of the polyester false twisting 2 layers of structure yarn that have the elongation rate variance more than 2 kinds bulkiness is improved, or, spontaneous elongation polyester mutifilament yarn and heat-contractable ployester multifilament textile knit by being mixed with air nozzle, or the lax heat treatment of enforcement, on one side to the polyester mutifilament yarn that the becomes spontaneous elongation heat treatment that relaxes, spontaneous elongation polyester mutifilament yarn after this lax heat treatment is supplied with the heat-contractable ployester multifilament textile continuously on one side, and mix method (for example, Japanese kokai publication hei 1-250425 communique) of knitting etc. with air nozzle.
Yet for common stretch yarn (FOY), even have antistatic behaviour, false twisting processing as described above or air are mixed to be knitted as if carrying out, the fluffing due to twisted distortion of generation or the friction easily, thereby actual conditions are to give sufficient antistatic behaviour.

Constitute polyester of the present invention mix knit yarn, antistatic polyester multifilament textile X is the core-sheath-type polyester complex fiber that core is made of copolyester B polyester A, sheath portion, this polyester A, B are the identical polyester of polyester A, B that uses in the core-sheath-type composite fibre with the application's the 1st invention.
And then the polyester A that requires the core/sheath portion in the cross section of polyester mutifilament yarn X and the area ratio of polyester B are 5: 95~80: 20 scope.The area ratio was less than 5: 95 o'clock, the embodiment of the antistatic property that is got by polyester a is insufficient, greater than 80: 20 o'clock, when then implementing the alkali decrement more than 10%, the antistatic polyester meeting stripping of core, antistatic property reduces, and the intensity of stretch yarn also reduces simultaneously, becomes below the 3.0cN/dtex, undercapacity when being made as cloth and silk, therefore be unsuitable for the purposes of desired strengths such as motion dress material, purposes is restricted, so not preferred.
Making polyester of the present invention mixes when knitting yarn, at first, as polyester filament yarn X ', employing utilizes present known compined spinning apparatus, higher spinning speed about aforementioned polyester a and b divided with 2000~5000m/ carry out spinning and polyester stretch yarn (usually, be called intermediate orientation yarn POY) not, perhaps use low oriented polyester that spinning speed about dividing with 1000m/ carries out spinning not stretch yarn or yarn that the intermediate orientation yarn is stretched and obtains with low range.
On the other hand, as polyester filament yarn Y ', preferably using boiling water shrinkage is polyester filament stretch yarn more than 8.0%, and then preferably to use boiling water shrinkage be 10~16% polyester filament stretch yarn.
As described polyester filament, but preferred illustration do not carry out heat setting the polyester filament stretch yarn, comprised copolymerization as the polyester filament stretch yarn of the polyester about 5~15 moles of % of for example M-phthalic acid of the 3rd composition.
As the fiber number of polyester filament yarn Y, preferred 2~10dtex.Then mixing the intensity of knitting yarn less than 2dtex can reduce, and so then quality hardening when surpassing 10dtex is not preferred.
Fig. 3 is that expression is used to make the front sketch that mixes an example of the device of knitting yarn of the present invention, polyester filament yarn X ' that will spontaneous stretching, draw together with polyester filament yarn Y ' by implementing lax heat treatment, by being arranged on the nozzle 3 that interweaves between donor rollers 1 and the 1st carry-over pinch rolls (warm-up mill) 2, under overfeeding, interweave.
In this device, the 1st carry-over pinch rolls 2 are heated, and between donor rollers 1 and the 1st carry-over pinch rolls 2, above-mentioned 2 kinds polyester filament yarn is by overfeeding, so circumvolution is subjected to lax heat treatment and spontaneous stretching in the polyester filament X ' of the 1st carry-over pinch rolls 2 on this roller.Then,, implement the 2nd lax heat treatment and mix the heat fixation of knitting yarn, batch and be package 6 by being arranged at the noncontact heater 5 between the 1st carry-over pinch rolls 2 and the 2nd carry-over pinch rolls 4.
When above-mentioned 2 kinds polyester filament yarn is interweaved, preferably use the longitude and latitude of 60~70/m staggered, therefore making over feed rate(OFR) usually is 1.0~1.5%, suits.
In addition, as above-mentioned example, with 2 heating of the 1st carry-over pinch rolls, implement lax heat treatment thereon when carrying out spontaneous stretching, it is compact that device becomes, so preferably, but compare with the over feed rate(OFR) that interweaves at nozzle 3 places that are suitable for interweaving, carry out the required over feed rate(OFR) of spontaneous stretching (relaxation rate) by lax heat treatment when bigger, carry-over pinch rolls also can further be set in the downstream of the 1st carry-over pinch rolls 2, and and these carry-over pinch rolls between implement the lax heat treatment of regulation.In addition, with the 1st carry-over pinch rolls 2 during as warm-up mill, it is littler than the diameter that strand advances side to make the strand of this roller 2 go out the diameter of side, and heat-treats with the over feed rate(OFR) (relaxation rate) of regulation on this roller.
The lax heat treated temperature and the over feed rate(OFR) (relaxation rate) of the spontaneous stretching of polyester filament yarn X ' according to which kind of yarn of use are changed as polyester filament yarn X ', for example, the intermediate orientation yarn (POY) that the spinning speed that use divides with 3000~3500m/ has carried out spinning, when relaxing heat treatment on the 1st carry-over pinch rolls (warm-up mill) 2, preferably to make roll surface temperature be 100~130 ℃, make over feed rate(OFR) (relaxation rate) is 1.0~1.5%.
The lax heat treatment that utilizes the 2nd stage of noncontact heater 5 is to be used for of the present invention mix knitted yarn and given the heat fixation of the characteristic of the spinning sample fabric that is suitable for making high resilience simulate wool sense of touch and handle, preferably 220 ℃~240 ℃, handle with 1.5~2.0% over feed rate(OFR), the processing time is generally 0.01~0.30 second.The gained polyester mixes the boiling water shrinkage of knitting yarn and is generally about 5~13%.As noncontact heater 5, can use slit heater, pipe heater etc.
Of the present invention mixing knitted in the yarn, after the polyester filament yarn X ' of the spontaneous stretching by lax heat treatment is interweaved with polyester filament yarn Y ', relax heat treatment so that the spontaneous stretching of polyester filament yarn X ', make polyester filament yarn Y ' carry out thermal contraction simultaneously, thus, can when the 2nd relaxes heat treatment, not contact under the situation of noncontact heater 5 by strand, stably make the mixed yarn of knitting of polyester, reduce the generation of broken end.
Polyester filament yarn X ' is relaxed heat treatment separately with after making it spontaneous stretching and carrying out heat fixation by the lax heat treatment in the 2nd stage, interweave with polyester filament yarn Y ' again and make polyester and mix and to knit in the method for yarn, when utilizing the noncontact heater to carry out the 2nd lax heat treatment, because strand contacts with the noncontact heater, it is also many to break end, so be not suitable for.
For the mixed yarn of knitting of polyester of the present invention, preferred single thread fiber number is that following ultra-fine fiber number of 1.5dtex and the polyester filament yarn X that contains antistatic additive are located opposite from the mixed outside of knitting yarn, polyester filament yarn Y mixes the inboard of knitting yarn with respect to being positioned at, in addition, polyester filament yarn X knits than (weight ratio) with the mixed of polyester filament yarn Y, the viewpoint of expanding from dark color, in weight ratio in 8: 2~5: 5 scope.Be preferably 8~6: 2~4.During for this scope, sense of touch, quality, soft feeling, intensity, etc. obtain balance, have good flexibility, resilience, sense of touch when being made as cloth and silk.
In addition, also preferably will be heat-treated in the temperature more than 100 ℃ by the gained woven and knit goods knit yarn or this fiber manufacturing that mixes of the present invention, be the suitable arrangementization due to the migration of polyethers and contained as required various additives with contained polyoxyethylene in the stabilisation of promotion structure and the fiber.And then also can and use lax heat treatment etc. as required
In addition, as required, can implement to process after the suitable hydrophiling to mix the woven and knit goods of knitting yarn or this fiber manufacturing by antistatic polyester of the present invention, and so be preferred.As processing after this hydrophiling, preferably for example can adopt, the method of handling with the aqueous liquid dispersion of the polyester polyether block copolymer that comprises terephthalic acid (TPA) and/or M-phthalic acid or their lower alkyl esters, low-grade alkylidene glycol and poly alkylene glycol, or hydrophilic monomers such as acrylic acid, methacrylic acid are carried out glycerol polymerization, then with method of its sodium saltization etc.
It is below the 2000V that mixed antistatic behaviour of knitting yarn of the present invention needs frictional electrification voltage.If then the generation of static is big more than the 2000V, when using, dress feels bad, and not preferred on safety yet.
Then, the application's the 4th working of an invention mode is elaborated.

Constitute polyester of the present invention mix knit yarn, antistatic polyester multifilament textile X ' is the core-sheath-type polyester complex fiber that core is made of copolyester B polyester A, sheath portion, this polyester A, B are the identical polyester of polyester A, B that uses in the core-sheath-type composite fibre with the application's the 1st invention.
It is more than 80% that above-mentioned antistatic polyester filament yarn X ' needs percentage elongation (ELA), be preferably 100~200%, elastic recovery rate (ERA) when needing 10% to stretch is below 50%, is preferably below 40%, and needing stretching modulus of rigidity (EMA) is 5.89GPa(600kg/mm
2) below, be preferably 1.96~4.91GPa(200~500kg/mm
2), needing crystallization degree (XpA) is more than 25%, is preferably 36~60%, the thermal stress (TSA) under needing 160 ℃ is 0.44mN/dtex(50mg/de) below, and then to need boiling water shrinkage (BWSA) be below 3%.
When showing above-mentioned characteristic, antistatic polyester filament yarn X ' is becoming float state to mixing to knit when yarn carries out heat treated, and applies loading at draw direction and also do not have the stress burden and only help bulkiness to improve, and the result has suppressed the generation of fold.
Antistatic polyester filament yarn X ' with above-mentioned characteristic, can be for example, utilize present known compined spinning apparatus, with aforesaid polyester a and b in 280~300 ℃ of following fusions of temperature, discharge from the spinning nozzle fusion, and give finish to the strand that spins of cooling curing, the use air jet hole is the device that longitude and latitude interlocks of giving more than 3 holes, the air of expulsion pressure 0.1~0.3MPa with give longitude and latitude staggered after, via preheat roll below the glass transition temperature that is set in polyester and draw roll (preheat roll hauling speed: 1500~2500m/ branch, stretching ratio: 1.1~1.5) temporarily batch on winder.
Then, with the gained stretch yarn with speed 500~1400m/ branch, via being heated to 70~110 ℃ preheat roll and being set in 170~240 ℃ contactless heater, implement heat setting (stretching ratio 1 is with the next relaxation heat setting that becomes) and obtain with 0.8~1.1 times stretching ratio.
Then, as constituting the polyester filament yarn Y ' (abbreviating filament yarn Y ' sometimes as) that mixes other composition of knitting yarn of the present invention, the loading of main burden draw direction and keep stability in morphological stability or the back manufacturing procedure, thereby to need percentage elongation (ELB) be below 40%, be preferably below 30%, needing stretching modulus of rigidity (EMB) is 7.85GPa(800kg/mm
2) more than, be preferably 8.83~14.7GPa(900~1500kg/mm
2).In addition, in order to show good bulkiness by heat treatment, needing boiling water shrinkage (BWSB) is more than 5%, be preferably 7~20%, and then, when after being made as cloth and silk, carrying out heat setting with pin stenter etc., not to aforementioned polyester filament yarn X ' stress application, and the reduction of inhibition quality, need make the thermal stress (TSB) under 160 ℃ be 0.88mN/dtex(100mg/dtex) more than, be preferably 1.76mN/dtex(200mg/dtex) more than.
For filament yarn Y ', for example, when the not drawing of fiber that will comprise aforementioned polyester stretches, can suitably regulate its draft temperature or stretching ratio etc. with above-mentioned characteristic.
For example, percentage elongation or modulus of rigidity are regulated by stretching ratio, and the heat-setting condition of boiling water shrinkage when stretching regulated and got final product.When particularly the expectation height shrank, non-plate stretching (non-plate drawing) etc. was suitable.Thermal stress can be by stretching ratio or the heating-up temperature when stretching and not the spinning speed of drawing of fiber regulate.But, when the spinning hauling speed is too high, the thermal stress after the stretching is uprised, so preferably divide following, preferred 1700m/ to divide the following low not drawing of fiber that spins speed to stretch to 2500m/.Should illustrate, the method for copolymerization the 3rd composition in polyester is arranged, for example, during copolymerization M-phthalic acid composition, can easily obtain having the product of high shrinkage character as other method of regulating above-mentioned characteristic.
Knit yarn for of the present invention mixing, after heat treatment that above-mentioned antistatic polyester filament yarn X ' is relaxed, need interweave with mixing with polyester filament yarn Y ' and knit.To strand implement to give thermal deformation, for example false twist crimping processing is not preferred, described method can not obtain the fold recovery effects.Its reason is speculated as, first, heat treated in the false twist crimping processing, stretch, reverse etc. causes the rerum natura of polyester filament yarn X ' to change, thereby percentage elongation reduces, thermal stress uprises or elastic recovery rate improves, thereby the character that forfeiture is extended is with a swish given when curling polyester filament yarn X ', interweave or resistance (opposing) increase with adjacent yarn, in fabric tissue, the position of departing from yarn is difficult to reinstatement, and easily fold takes place during cloth and silks such as formation fabric.
Should illustrate, in utilizing the situation that interweaves of aerojet, the injection direction of air can be and the rectangular direction of yarn, also can spray along the direct of travel of yarn, but can obtain the more excellent product of gloss by the former, then can obtain the soft product of quality by the latter.
Further, between polyester filament yarn X ' and the polyester filament yarn Y ' the overfeeding difference can be set and carry out air combined processing, but difference is when excessive, then coil is a large amount of easily produces, thereby adopts roughly the same over feed rate(OFR) usually.
The compositely proportional of polyester filament yarn X ' and polyester filament yarn Y ' (mix and knit ratio) in the weight ratio of polyester filament yarn X ', polyester filament yarn Y ', need be 45/55~70/30.
Especially, the ratio of polyester filament yarn X ' is many more, then is easy to generate effect of the present invention more, thereby in the part by weight of polyester filament yarn X ', polyester filament yarn Y ', preferred especially 55/45~70/30.Should illustrate that now for polyester filament yarn X ', polyester filament yarn Y ', each is that example is illustrated with 1 rhizoid bar, but from needless to say be the strand that also can use more than 2, in brief, so long as satisfy fiber, then use how many rhizoid bars can as the rerum natura of important document of the present invention.
Further, even the 3rd strand that the discontented unabridged version of interpolation is invented described above-mentioned rerum natura carries out compound also passable.For example, can composition metal plating fiber or carbon particle sneak into fiber, giving electric conductivity, but the ratio of such fiber is when too much, restorative improvement becomes insufficient as the fold of purpose of the present invention, so it is desirable to and be up to 30% with rate.
Should illustrate, the antistatic behaviour core-sheath-type polyester fiber that uses in the application's the 1st invention~the 4 invention, on its filament cross section, the projection coefficient that preferably has 3~8 following formulas definition be 0.3~0.7, from the outstanding laterally fin of fibre section core
The projection coefficient=(a1-b1)/a1
A1: from the length on inscribed circle center to the fin summit of fibre section inner surface
B1: the inscribe radius of a circle of fibre section inner surface (core extrapolation inscribed circle).
Polyester complex fiber of the present invention with above-mentioned characteristic and cross sectional shape, can tolerate draw false twisting and add the impact that is subjected to man-hour, even under common condition, carry out draw false twisting, also can under adding the few condition of generation of the broken end (processing broken yarn) in man-hour and fluffing, draw false twisting stretch, because polyether polyols is that antistatic additive exists with elongated bar form on the fiber axis direction fully, so antistatic behaviour is good.In addition, for gained draw false twisting processing yarn, the flat degree of its fiber cross section appropriateness on the fiber axis direction is disperseed, on the fiber axis direction, become and fibre section inequality, form the big fiber assembly in space between fiber, bring the effect of the washing resistance raising of water-absorbing fast-drying performance and this performance.Further, the flat degree in the fibre section fiber assembly that appropriateness is disperseed on the fiber axis direction also has the performance of bringing the natural dry feeling in the cloth and silk simultaneously.
In addition, water absorbing properties, antistatic behaviour and the process stability of above-mentioned antistatic behaviour core-sheath-type polyester fiber are good.Its reason is still indeterminate, but can be presumed as follows: be used as the core antistatic additive by using hydrophilic polyether polyols system and ionic compound as antistatic additive, cause water imbibition to be promoted to more than single water imbibition by the capillarity due to the projection of given shape, in addition, when spin-drawing, particularly when stretching, resistance decreasing between fiber, so antistatic additive is stretched on the fiber axis direction equably, become and have proper aspect ratio, fluffing simultaneously takes place few, and process stability is good.
The projection coefficient of the filament cross sectional shape of antistatic behaviour core-sheath-type polyester fiber (concrete example is Fig. 5) is 0.3~0.7, more preferably 0.4~0.6.Requirement presents following shape, and promptly the number that exists from the outstanding laterally fin of fibre section core (Fig. 5 1) is 3~8, is preferably 4~6.
This projection coefficient does not have the function that forms sufficient capillary interstice on the fibre section after the draw false twisting processing less than 0.3 fin, can not embody the water-absorbing fast-drying performance.And then this short and small fin diminishes because cloth and silk is applied the anchor effect of suction during finishing agent, so there is the tendency of the washing resistance reduction that makes this finishing agent.In addition, the quality of cloth and silk becomes smooth paper sample.On the other hand, the projection coefficient surpasses 0.7 fin, concentrates machine tensions on man-hour, this fin easily because draw false twisting adds, so produce the partial destruction of fibre section, can not form capillary fully, and it is insufficient that water absorbing properties becomes.In addition, broken end in the draw false twisting operation (processing broken yarn) or fluffing also take place frequently.
Should illustrate, even the projection coefficient is 0.3~0.7 fin,, then is closed in inboard fibre section part and can only forms maximum 1 if when the number of this fin is 1~2 on the filament cross section, so can not embody sufficient capillarity, it is insufficient that water absorbing properties becomes.In addition, the quality of cloth and silk also becomes smooth paper sample.On the other hand, when surpassing 8, the machine tensions that draw false twisting adds on man-hour, the generation fin is concentrated, and causes the partial destruction of fibre section, can not fully form capillary, and it is insufficient that water absorbing properties becomes.In addition, broken end in the draw false twisting operation (processing broken yarn) or fluffing also take place frequently.Should illustrate that the projection coefficient also can exist above 8 less than 0.3 fin.
Above Shuo Ming antistatic behaviour core-sheath-type polyester complex fiber of the present invention, can make by the tap of regulating known core sheath composite spinning machine, for example, can form the radius (a2 of Fig. 6) that portals with circular row, central point to fin that this circular row is portalled and form with the length (b2 of Fig. 6) of the leading section of tap etc. by changing core, be 0.3~0.7 mode and setting arbitrarily with the projection coefficient of fibre section.In addition, by changing the temperature and/or the cooling air quantity of spill spin block (spin block), the also projection coefficient in controlling fiber cross section to a certain extent.
In addition, the antistatic behaviour core-sheath-type polyester fiber that uses in the 1st invention~the 4 invention for the application, requiring the cross section vertical with the single thread length direction is flat pattern, have the shape that 3~6 circular section single thread engage in the vertical, and the bonding part is formed with necking section (constricted part) (with reference to Fig. 7).
In the situation of the shape that common circular section single thread or 2 circular section single thread engage, core-sheath-type polyester flat cross section fiber in the fabric is difficult to be formed on the set form of expanding on the cross direction, the space (tissue space) that is formed by warp thread and weft yarn becomes big, its result, light passes through from this space, might can not get anti-fully observability, so not preferred.On the contrary, when surpassing 7, then throwing becomes difficult, so not preferred.
Then, aforesaid necking section shown in pattern ground among Fig. 8, is meant the part that the length of minor face shortens.In the described necking section,,, be preferably the degree of depth of (preferred more than 1.1) more than 1.05 in the ratio B/C of maximum (B) with the minimum of a value (C) of the length of minor face as concave depth.In addition, among Fig. 8, illustration recess be formed at the example of both sides, but also can only on a side sidepiece, form recess.And the number of this necking section need be for more than 2, and the necking section is 1 and can not get gratifying anti-observability can not get the diffuse reflection of sufficient light or the refraction of transmitted light in the next necking section, so not preferred.As long as the number of this necking section is then to be not particularly limited more than 2, but when considering throwing, 3~5 is suitable.Should illustrate that Fig. 8 is illustrative to be that the necking section is 2 a situation.
For above-mentioned antistatic behaviour core-sheath-type polyester fiber, because its shape of cross section is special flat, so when weaving, owing to the contact pressure of fabric tissue point, and the structure that has densification and on cross direction, expand.Its result, the space that is formed by warp thread and weft yarn diminishes, and reduces from the throughput of the light in this space.At this moment, the transmitted light generation diffraction of the trace by this space by interfering mutually with adjacent transmitted light, and obtains excellent anti-visual effect.
Further, because making the shape of cross section of long filament is the flattened with specific necking section, and the content that makes delustering agent is below the specified quantitative, so compare with smooth flat cross section yarn, circular section yarn, triangle section yarn with fiber number, the diffuse reflection of light or the refraction that sees through the transmitted light of long filament become big, can obtain excellent anti-visual effect and do not damage daylighting.
In addition, core-sheath-type polyester flat cross section fiber is owing to having the structure of expanding, so the flexural rigidity step-down also has been endowed soft quality on cross direction.And then on fabric tissue point, necking section (recess) is difficult to contact other yarn, so the less traction of warp thread and weft yarn can obtain further tender texture than having smooth flat pattern person.
