Description
Technical field
The present invention relates to comprise the textured yarn of synthetic fiber multifilament, it has filoplume and the bulkiness that is similar to staple fibre yarn, is used to make the woven fabric of soft feeling and commodity position feel, and also relates to its production method.
Background technology
Up to now, carried out various effort and made synthetic multifilament have such filoplume of staple fibre yarn and bulkiness, and proposed the long filament of many kind band filoplumes.The filament yarn of common band filoplume is with such method production, and in the method, multifilament is nuzzled up on an edge of a knife by false twisting or twisting simultaneously.But this method has a shortcoming, and promptly the passing edge of a knife of subsidiary time can wear and tear gradually, thus in the longitudinal direction As time goes on the intensity of the number of filoplume and yarn also can change, the result causes the yarn evenness of band filoplume filament yarn irregular.
A kind of long filament with filoplume is disclosed in unexamined Japanese Patent Application Publication specification No.3-64546, it has overcome the evenness fault of yarn, it is to produce like this, two multifilament self that go to thread-carrier and return from thread-carrier are intersected, hang over by the multifilament that will have first twist and twist with the fingers eventually and apply distortion on the thread-carrier and friction makes the multifilament fluffing.
The filament yarn quality of the band filoplume of Sheng Chaning improves in this way, As time goes on still has stable hairiness number and yarn intensity in the longitudinal direction.But the filoplume of this band filoplume filament yarn is very short, has only 1mm long or shorter, makes bulkiness very poor.Therefore the woven fabric made from this band filoplume long filament can not make woven fabric have soft feeling and high-grade feel.In addition, this band filoplume filament yarn is owing to intersect mutually standing first twist and twist with the fingers eventually processing back multifilament, thereby can not obtain gratifying yarn intensity.
On the other hand, when using as sewing thread, above-mentioned common band filoplume filament yarn can cause following problem.
Cotton sewing thread has good sewing performance, thereby is widely used in family's sewing and the industrial sewing.But the shortcoming of cotton sewing thread is an intensity difference, the dyefastness deficiency.In addition, it is that it can cause change in size that cotton sewing thread also has shortcoming, the feasible needle tracking appearance poor of finishing.On the other hand, occupy the polyester staple fibers sewing thread of half or the more sewing thread market share, have the sewing performance similar, and high intensity, dyefastness and DIMENSIONAL STABILITY are arranged to continuous sewing thread.But, because the polyester staple fibers sewing thread is to be made by staple fibre yarn, be unsafty qualitatively, for example, there is the very wide tieing of distribution to exist.Also have, because the appearance poor of needle tracking, the polyester staple fibers sewing thread is not used in the sewing of high-quality ready-made clothes.
On the other hand, by silk, the sewing thread that polyester or polyamide filaments yarn are made has been widely used as sewing thread, and it has overcome the problem that above-mentioned cotton or polyester staple fibers sewing thread are caused.Producing common long filament sewing thread is that many single thread that will have first twist lump together, and then carries out whole sth. made by twisting.Correspondingly, depend on the fineness of single thread and total yarn fineness, the long filament sewing thread can have good physical property, and this makes the long filament sewing thread that stabilized quality be arranged.
Chang Gui long filament sewing thread promptly can not cause any trouble with an extreme trace Sewing machines in sewing forward in common sewing like this.But such long filament sewing thread can cause serious problem in sewing backward, because the power that is added on the long filament sewing thread is the untwisting direction of twisting with the fingers eventually along it, can produces sewing thread and rupture because of the twist disappears.In other words, common long filament sewing thread can not be used for the machine stitching of automation, and the frequency of sewing backward in the sort of sewing Shen is very high.When the long filament sewing thread is used for the high speed sewing of industrial sewing machine, the fracture of line also takes place possibly, this is that heat by the machine stitching pin causes, and heat is because the big frictional resistance on long filament sewing thread surface and the long filament sewing thread penetration resistance to clothes is produced.
Consider these situations, proposed the sewing thread of some kind, they can overcome these shortcomings of common short fiber sewing thread or long filament sewing thread.For example, Japan Patent prospectus No.63-3977 discloses a kind of core pattern sewing thread, and it has the skin-core structure of long filament and staple fibre yarn composition.Unexamined Japanese Patent Application Publication specification No.2-33341 discloses a kind of sewing thread with improvement sewing performance, and it is formed in conjunction with yarn by the staple fibre yarn of the band twist and the twisting that long filament constitutes.But because these sewing threads are made by spinning process, they have tieing or the uneven part of size probably, and this can cause thread breakage in the sewing process.
On the other hand, unexamined Japanese Patent Application Publication specification No.2-104733 and 5-106134 disclose the method that is used to improve long filament sewing thread sewing performance, in the method long filament is carried out fluid treatment and produces looped pile, obtain the long filament textured yarn sewing thread of like staple fiber yam thus.Though sewing thread of being made up of such long filament textured yarn and short fiber sewing thread or uniform structure is arranged by comparison by the sewing thread that staple fibre yarn and long filament constitute, its high-speed sewing performance is very poor, and the needle tracking after making also is difficult to see.
In order to improve the shortcoming of common band filoplume long filament textured yarn, the present invention is at unexamined Japanese Patent Application Publication specification No.1-2722840,2-91236,2-216233,3-27144, among 3-64546 and the 4-091245, the spun replacement yarn textured yarn of yarn and yarn self friction fluffing has been proposed.
But long filament textured yarn although it is so can improve the uniformity of filoplume in the longitudinal direction, is not exclusively gratifying but conduct has the long filament textured yarn of filoplume similar to staple fibre yarn and bulkiness.
Therefore, target of the present invention provides a kind of long filament textured yarn that has spun yarn like fluff, and promptly it has filoplume similar to staple fibre yarn and bulkiness, is used to make the woven fabric of soft feeling and high-grade feel, and the production method of this yarn is provided.

The specific embodiment
The long filament textured yarn that the present invention has spun yarn like fluff is a kind of long filament textured yarn, it is to produce like this, there is the multifilament of first twist to flock together with many, then they are twisted with the fingers eventually, a part of monofilament of wherein forming multifilament is cut into short silk, at least one ends of these short silks by or first twist or twist with the fingers eventually be fixed in the multifilament, thereby the outstanding filoplume that becomes from the multifilament surface, have on every meter of such long filament textured yarn 100 to 400 length be 1 to 5 millimeter filoplume and 30 or more a plurality of length be 1.5 to 5 millimeters filoplume, and the intensity of yarn was 4.7 to 6 gram/dawn.
Show that in Fig. 1 the present invention has an embodiment of the long filament textured yarn of spun yarn like fluff.In Fig. 1, Y
KBe the long filament textured yarn that has spun yarn like fluff, Y is the multifilament that first twist is arranged, and A and B are each filoplumes.
The long filament textured yarn Y that in Fig. 1, has spun yarn like fluff
KComprise the many multifilament Y that first twist is arranged, multifilament is collected at together, and awards sth. made by twisting processing eventually.Each comprises the multifilament of a lot of monofilament naturally multifilament Y, and wherein a part of monofilament is cut into short silk randomly at length direction.At least one end of each short silk by or first twist or twist with the fingers eventually be fixed in the multifilament, and the other end can be freely outstanding as filoplume A from the multifilament surface, also can still be fixed in the multifilament and gives prominence to as looped pile shape filoplume B from the multifilament surface.Preferably these two kinds of filoplume A and B do not have to curl, and the shape that is in line basically.
Yarn Y from the band filoplume
KOutstanding filoplume A and B are at the yarn Y of band filoplume
KLast every meter to each have 100 to 400 length be that 1 to 5 millimeter filoplume and 30 or more a plurality of length are 1.5 to 5 millimeters filoplume.Because the yarn Y of such band filoplume
KComprise a large amount of filoplumes, every meter have respectively as many as 100 or more a plurality of length be 1 to 5 millimeter filoplume with 30 or more a plurality of length be 1.5 to 5 millimeters relative long filoplumes, it has extremely soft hand feeling of like staple fiber yam, but does not examine the disclosed common just never so excessively feel of band filoplume filament yarn among the Japanese Patent Application Publication specification No.3-64546.
The feature of long filament textured yarn of the present invention will be elaborated with reference to figure 2.
Among Fig. 2, the quantity of each the curve shows filoplume that shows and the correlation between the length, represent the long filament textured yarn (it obtains) that has spun yarn like fluff according to of the present invention separately from following example 1, a kind of common band filoplume filament yarn (it obtains from following comparative example 1), another kind of common band filoplume filament yarn (it obtains from an above-mentioned comparative example 2), (can buy on the market with a kind of staple fibre yarn of comparative example 3, spin (Toyobo) Co., Ltd produce and market by Japan, model is " C100#60 ").
The data of Fig. 2 are to be to measure under 60 meters/minute the condition to obtain in the yarn speed of service with " DT-104 type filoplume counter " (by east beautiful (Toray) Engineering Co., Ltd produce and market).In Fig. 2, its length is drawn on the figure as ordinate (being the filoplume number) greater than the filoplume sum of abscissa numeral.
As shown in Figure 2, about length at 1 millimeter or above filoplume number, the staple fibre yarn of comparative example 3 has 160 filoplumes for every meter, and the long filament textured yarn of example 1 has 140 filoplumes for every meter, and comparative example 1 and 2 common band filoplume filament yarn all have 30 or less filoplume for every meter.At 1.5 millimeters or above filoplume number, the long filament textured yarn of the staple fibre yarn of comparative example 3 and example 1 all has 50 filoplumes for every meter about length, and the common band filoplume filament yarn of comparative example 1 and 2 has 5 or less filoplume for every meter.
Reach a conclusion from this result, as shown in Figure 2,1 millimeter or above filoplume distribution, long filament textured yarn of the present invention and staple fibre yarn are quite similar for length in multifilament.Therefore, although be the feel that filament yarn also demonstrates like staple fiber yam.
In this test, term " filoplume number " refers to the sum of these filoplumes, is cut off freely (filoplume A) outstanding from the yarn surface and an end in the filament yarn surface and (the filoplume B) of sagging formation looped pile comprising an end of filoplume.Especially, the sum of filoplume can be to measure under 60 meters/minute the condition to obtain in the yarn speed of service by " DT-104 type filoplume counter " (by east beautiful (Toray) Engineering Co., Ltd produce and market).
When length in the long filament textured yarn at the number of 1 to 5 millimeter filoplume less than every meter 100 and length at the number of 1.5 to 5 millimeters filoplume during less than every meter 30, the long filament textured yarn no longer shows the feel of like staple fiber yam.On the other hand, when length in the long filament textured yarn at the number of 1 to 5 millimeter filoplume during greater than every meter 400, in (use long filament textured yarn) woven fabric or knitwear, can produce pilling effect probably, perhaps penetrating of cloth be become very poor with the sewing thread that the long filament textured yarn is made.
Have in the long filament textured yarn of spun yarn like fluff in the present invention, as described in the production method described as follows, filoplume is to produce on yarn in the step of first twist.Therefore the long filament textured yarn has high yarn strength, and fracture strength was 4.7 to 6 gram/dawn.Because high like this yarn strength, when using sewing thread with the long filament textured yarn as machine, it demonstrates fabulous high-speed sewing performance and automatic sewing performance.
Generally, the fracture strength of the high strength type filament yarn of no filoplume (having first twist and whole the sth. made by twisting) was 6 to 7 gram/dawn.But, when such filament yarn as machine when using sewing thread, its high-speed sewing performance and the automatic sewing performance extreme difference that becomes.This is because because such filament yarn do not have filoplume, the frictional resistance between line and the machine stitching pin becomes very high, thereby makes pin produce a large amount of heats and make and the line fusion cause broken end.In the present invention, term " intensity " refers to the value of measuring according to the method for stipulating among the JIS L-1073.
In the present invention, constitute each root in the many multifilament of the long filament textured yarn have spun yarn like fluff and comprise that long filament with thickness monofilament consistent with each other or at least two kinds have the mutual difference long filament of the monofilament of thickness separately.
In the multifilament that comprises last type of long filament, long filament is cut into short silk without exception by fluffing processing.On the other hand, in the multifilament that comprises back one type of long filament, the less long filament of monofilament fineness is cut into short silk selectively because the bigger long filament of monofilament fineness difficulty be cut into short silk.Thereby, at latter event, there is the long filament of less monofilament fineness preferentially to be cut into short silk, so that the filoplume of required quantity to be provided, and the long filament that big monofilament fineness is arranged provides the desirable strength of gained long filament textured yarn, thereby increases the number of filoplume and the intensity of long filament textured yarn is improved.
When multifilament comprises the long filament of two types of for example having different separately monofilament finenesses, preferably that the monofilament fineness of monofilament fineness 0.1 to 1.5 DENIER (denier) is less long filament and monofilament fineness are combined at the bigger long filament of the monofilament fineness of 3.5 to 10 DENIER, and the difference of two class long filament DENIER is in 2 DENIER or more some more.
From enough this viewpoints of filoplume are provided, the long filament number of forming multifilament preferably 30 or more, so that for woven fabric or knitwear provide soft hand feeling, produce uneven viewpoint from preventing suede balling-up and multifilament surface, long filament number preferably 300 or still less.
With regard to filamentary material,, there is not special restriction as long as long filament is that a kind of synthetic fiber are just passable as long filament textured yarn of the present invention.But preferably use a kind of thermoplastic synthetic fiber's long filament, low elongation and high-intensity polyester fiber and nylon fiber are for example arranged.
In the present invention, best multifilament has total fibre fineness of 50 to 500 DENIER.When long filament textured yarn of the present invention was used sewing thread as machine, preferably its multifilament had 100 to 300 DENIER total fiber fineness, and comprises 50 to 250 threads.
In general, one filament is circular cross section.But when being used for making ready-made clothes, one filament can be for other cross section, as triangle, the Y type, pentagon, hollow or flattened cross-section.Also can use the monofilament of specific type, as high glaze fiber or low luster fiber.
When multifilament comprises at least two kinds of long filaments that each have different monofilament finenesses,, the long filament that be cut into short silk can be provided and can not be cut into the difference of silk intensity between the long filament of short silk according to the difference of above-mentioned monofilament fineness.In addition, multifilament can include at least two kinds of long filaments of identical monofilament fineness, uses different materials or uses different processing methods by various long filaments, and the difference of silk intensity between them or percentage elongation can be provided.
In this case, preferably use two or three long filament that each has different monofilament finenesses.But also can use 4 kinds or more kinds of such long filament.From the angle of easy production, preferably simultaneously produce long filament that two or more each have different monofilament finenesses with a spinning head from a kind of polymer in this step of spinning by melt spinning.
But they also can be produced by this way, the long filament of less monofilament fineness is arranged and have the long filament of big monofilament fineness to spin respectively, then two kinds of long filaments that obtain are flocked together.
To illustrate that now production the present invention has the method for the long filament textured yarn of spun yarn like fluff.
At first, will have many multifilament of first twist to flock together, and hang on the thread-carrier then, and the guiding multifilament is with forward and return two kinds of directions and walk around thread-carrier.Then, make the multifilament fluffing by self the intersecting of two multifilament of going to thread-carrier and return from thread-carrier.At last, the multifilament that obtains is handled through twisting with the fingers eventually again, thereby obtains to have the long filament textured yarn of spun yarn like fluff.In this method, when being flocked together, multifilament adds big distortion and makes its phase mutual friction that this is very important to the multifilament fluffing that makes first twist.
With regard to the twisting machine that carries out first twist processing in being used in the first twist process, can use so-called uptwister, coating machine, conventional type (Italian type) twisting machine, downstriker twisting machine or two-for-one twister.Add man-hour when using such twisting machine to fluff, the multifilament that first twist arranged supply yarn with the recoil of vertical recoil or level, the yarn of many gained (promptly work as yarn flocks together or before yarn batches) processing of fluffing in the yarn Operational Zone then.
Fig. 3 shows the embodiment of the long filament textured yarn production method have spun yarn like fluff, and three multifilament that wherein will be in advance award first twist with uptwister flock together, and make its continuous fluffing then.In Fig. 3,1a, 1b and 1c are spools separately; 2a, 2b and 2c are spindles separately; The 3rd, driving belt; 4a, 4b and 4c are yarn feed rollers separately; The 5th, thread-carrier; The 6th, yarn feed roller; The 7th, bobbin; The 8th, winding roller; The 9th, the guide roller; The 10th, bearing pin; The 11st, guide roller, Y

As shown in Figure 4, the friction by multifilament they self makes the multifilament fluffing.In the embodiment depicted in fig. 4, by mode shown in Figure 4 two multifilament are crossed one another, to two multifilament Y
0And Y
0' can apply the distortion of about 90 degree.Make multifilament to pass through the crosspoint with the direction of returning forward, the result generally speaking has the distortions of 180 degree to be added on the multifilament approximately.
In this fluffing processing, be added in the distortion on the multifilament and the effect stability of friction in order to make at crosspoint P, bearing pin 10 (see figure 4)s or a roller are preferably disposed on the inboard of crosspoint P.As guide roller 9 (as shown in Figure 4) or bearing pin being placed on the multifilament supply side of crosspoint P, the multifilament outlet side that guide roller 11 (as shown in Figure 4) or bearing pin is placed on crosspoint P is just better.Thereby any one direction that refers to along each arrow shown in Figure 4 when guide roller or bearing pin at the multifilament outlet side moves the pipeline of moving direction and yarn when intersecting, and will be changed by multifilament that goes to the guide roller and the angle θ that multifilament constituted that returns from the guide roller.According to the size at θ angle, the intensity of distortion and friction just may change, thereby regulate the number of filoplume on the multifilament.
In this friction process, the tension force on being added to multifilament, on two multifilament that go to the guide roller and return, preferably add 0.3 gram/dawn or bigger tension force from the guide roller.In order to apply required distortion, angle θ is 180 degree or bigger preferably, as 360 degree or above just better.When the θ angle is 180 degree or bigger, when the distortion that causes by intersection was added on the multifilament, half of multifilament excircle or more than half multifilament that moves with opposite direction contacted, thereby are rubbed.
Concerning the direction of the distortion that caused by intersection, perhaps S direction or Z direction all can be used.But, two multifilament are crossed one another with the direction identical with the first twist direction and twisted from increasing the viewpoint of multifilament filoplume number.For the length of filoplume, length just shortens when giving the bigger first twist amount of twist of multifilament, and therefore length is just elongated when to the less first twist amount of twist of multifilament.Like this, the length of filoplume can be regulated in 1 to 5 millimeter scope.
In friction process, preferably the speed of service of multifilament is 3 to 100 meters/minute, this is favourable to the intensity that prevents to reduce yarn, because because fricative a large amount of frictional heats or owing to the scratch of long filament causes the fragility of long filament to degenerate, make intensity decreases, can also prevent multifilament the fading and on filament surface, produce the powdery chip of white of friction position, and boost productivity.
