Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a polyester horny yarn having a natural dyed shade and a method for manufacturing the same,

More particularly, the present invention relates to a polyester horny yarn having a natural dyeing and tinting color which smoothly improves the touch feeling of a fabric, and more particularly, To a polyester horny yarn having a natural dyeing and shading color with remarkably improved touch feeling and a manufacturing method thereof.

In order to have a natural surface effect on the polyester fiber, it is possible to have a thin and thick (TTD) effect having a natural dyeing shade difference in the direction of the silk thread by controlling the speed acting on the filament, the stretching ratio and the stretching temperature. Specifically, in order to have a natural dyeing shade difference, conventionally used methods are to uniformly impart the emulsion imparted to the filaments radiated in the yarn manufacturing process, or to disperse the irradiated filaments through a low heat fixation temperature, Monosaccharide The difference in dyeing tint was expressed through the preparation of the stamina so that the fineness was uneven in the longitudinal direction.

On the other hand, the process of dyeing a polyester fiber including ordinary yarn or a yarn-containing yarn is generally performed under high pressure and high pressure. Specifically, dyeing of the polyester fiber is mainly performed by using a disperse dye at a high temperature and a high pressure. It is almost impossible to use other dyestuffs in polyester dyeing. The main reason that disperse dyes are mainly used is that the seated seats of polyester fibers (hollow spaces in which the dyes enter into the fibers, intervals of fiber molecules) are small and hydrophobic, Because there is almost no coupling capability between the two. As a result, a dye having a small molecular weight, a hydrophobic (lipophilic) property and a non-ionic property is required as a dye capable of being dyed, and thus a disperse dye may be more suitable than other dye . However, even though such dispersed dyes have the smallest cross-sectional area of about 10 to 20 Å in diameter (about 20 Å in diameter), even such small disperse dyes in polyester fibers are difficult to penetrate into the fibers, C. or higher) or Carrier dyeing to increase the spacing of the fiber molecules and forcing the disperse dye molecules to penetrate into the fiber. Korean Patent Publication No. 1993-0013361 discloses a dyeing method of polyester fibers .

Accordingly, in the case of the polyester staple yarn among the above-mentioned methods for manifesting the difference in dyeing density, high temperature and high pressure conditions are required in the step of dyeing the yarn or dyeing the fabric after the yarn is woven.

However, in the case of the polyester staple fiber, since the polymer contained in the fiber is produced by performing the low heat fixation temperature and the heterogeneous stretching so as to have low orientation, the yarn is shrunk and shrunk in the high temperature and high pressure dyeing process, And the drapeability is remarkably reduced, so that it is very difficult to develop the fabric into clothes, and even if the fabric is made into a garment, the feeling of wearing is remarkably deteriorated.

4 is an enlarged cross-sectional view of a cross-linked yarn according to a preferred embodiment of the present invention.

Hereinafter, the present invention will be described in more detail.

As described above, in the case of the conventional polyester fiber, high temperature and high pressure conditions are required in the process of dyeing yarn or dyeing a fabric after weaving the yarn, and this is a method of producing a difference in dyeing density, It was no exception. However, in the case of the polyester staple fiber, since the polymer contained in the fiber is produced by performing the low heat fixation temperature and the heterogeneous stretching so as to have low orientation, the yarn is shrunk and shrunk in the high temperature and high pressure dyeing process, The fabric is very difficult to develop into clothes, and even if it is made into clothes, the feeling of wearing is considerably deteriorated.

Therefore, in the present invention, it is preferable that the first yarn is a polyester yarn having a non-uniform monosaccharide fineness, and the second yarn has a monosan fineness of 0.3 to 1.2 denier Polyester yarn and polyester yarn having a natural dyeing and shading color which is soft and improved in touch feeling of the fabric. As a result, after the dyeing of the fabric, the fabric exhibits a natural dyeing and shading effect, and at the same time, the touch feeling of the fabric is improved, so that the softness of the fabric can be improved.

First, the blended yarn according to the present invention is not a yarn blended yarn that is mixed through one spinneret, but is a mixed yarn produced by fusing at least two kinds of yarns separately and independently manufactured.

The first yarn is a polyester yarn having a non-uniform monosaccharide fineness and the second yarn has a monodispersity of 0.3 to 1.2 denier Lt; / RTI >

According to a preferred embodiment of the present invention, the blended yarn may be a blend of the first yarn and the second yarn at a weight ratio of 1: 0.15 to 2.0, through which the woven or knitted fabric or knitted fabric including the horny yarn is dyed It is very advantageous for the development of the intended physical properties such as expressing the dyeing shade tea which is remarkably natural afterwards and at the same time the fabric is not hardened even after dyeing at high temperature and a remarkably smooth touch feeling is expressed. If the amount of the second yarn is less than 0.15 by weight, the fabric including the mixed yarn may not have a soft touch feeling such as a hardened fabric after the high-temperature dyeing process. In addition, when the second yarn is contained in an amount of more than 2.0 wt% as compared with the first yarn, the fabric may not exhibit a natural dyeing tint difference after dyeing.

In addition, the mixed yarn may have a total fineness of 100 to 500 denier in which the first yarn and the second yarn are hybridized. If the yarn is less than 100 denier, the productivity is lowered due to too low denier, There is a problem in that the desired processability can not be secured and even if the first yarn and the second yarn are mixed at an appropriate weight ratio, there is a problem that desired physical properties such as lowered sharpness of the dyeing difference, . In addition, if it exceeds 500 denier, the use may be limited due to too high denier, and there may be a problem that the uniformity of the cross-linked membrane is lowered due to the high denier at the time of producing the hornblende. However, the total fineness of the cross-linked yarn can be designed differently depending on the purpose, and is not limited to the above-mentioned range.

On the other hand, the mixed yarn according to one preferred embodiment of the present invention can satisfy the following conditions (1) to (4).

(1) Shrinkage 20 to 70% (2) Shrinkage rate 15 to 25% (3) Risona shrinkage 15 to 25% (4) Shrinkage rate 25 to 45%.

The mixed yarn according to the present invention can satisfy the elongation of 20 to 70%, more preferably 20 to 55%, and even more preferably 20 to 40% as the preferable condition (1) Or more, it is possible to improve the durability of the fabric by improving the processability in the production of the fabric. If the elongation is less than 20%, the elasticity of the cross-linked yarn is weak, which may result in deterioration in processability in weaving or knitting, and there may be a problem in that the fabric is hardened after dyeing the fabric including the filament yarn at high temperature and high pressure, The sense of touch of the fabric is remarkably reduced, so that it may be inappropriate for use as clothes, and the feeling of wearing at the time of manufacturing may be lowered as clothes. In addition, if the elongation exceeds 70%, the mechanical strength may be remarkably lowered, and the ability to perform the weaving process may be remarkably deteriorated, and even if the fabric is made into a fabric, the durability during use may be significantly reduced.

Next, the blended yarn according to the present invention can satisfy the non-water shrinkage ratio of 10 to 25% as a preferable condition (2), and the shrinkage or hardness of the fabric is significantly prevented in the high-temperature dyeing process, Can be improved. If the difference in the stiffness of the first yarn is low, it may be difficult to develop a natural shade difference. If the shrinkage percentage of the non-shrinkage exceeds 25%, the shrinkage of the yarn due to the high temperature may cause shrinkage of the fabric during high- If a shrinkage occurs, the fabric may be staggered, and the fabric may become stiff and the touch feeling may be significantly reduced.

Next, the mixed yarn according to the present invention is a preferable condition (3), and the rinse or shrinkage ratio can be 15 to 25%, whereby when the woven fabric is woven, the stretchability of the conventional polyester yarn having unevenness in fineness is improved And the yarn can be remarkably prevented from being woven in the weaving process so that the productivity of the fabric is improved and the fabric can express a soft touch even in a high temperature dyeing process.

The recurrence rate is a percentage of the original length of the shrunk length after heat treatment in water at 82 +/- 3 DEG C for 10 minutes with a load of 20.5 g applied to the yarn in the yarn state, Shrinkage characteristics and elongation and shrinkage characteristics, and the higher the value, the stronger the shrinkage and stretch properties.

If the shrinkage ratio is less than 15%, the yarn is remarkably truncated in the weaving process and is difficult to be made into a fabric, and even if it is produced, there may be a problem in that the fabric is hardened after a high temperature dyeing process. On the other hand, if the shrinkage percentage of the yarn exceeds 25%, there is a problem that the shrinkage characteristics of the yarn are excessive, and the fabric may become stiff due to excessive shrinkage after the fabric is dyed.

Next, as the preferable condition (4), the residual shrinkage ratio of the present invention can be 25 to 45%, more preferably 30 to 45%, and when the knitted fabric is knitted therewith, It is possible to have more improved stretchability than a polyester post-warp yarn, to improve the productivity of the knitted fabric by significantly preventing yarn splicing in the knitting process, and to soften the touch feeling of the fabric even in a high- can do.

The residual shrinkage percentage is a percentage of the original length of the shrunk length after heat treatment for 10 minutes in water at 82 ± 3 ° C with a load of 1.5 g applied to the drawn yarn in the twisted state, Shrinkage characteristics and elongation and shrinkage characteristics, and the higher the value, the stronger the shrinkage and stretch properties.

If the residual shrinkage ratio is less than 25%, the yarn is remarkably truncated in the knitting process, so that the knitted fabric is difficult to be knitted, and even if it is produced, there is a problem that shrinkage of the fabric becomes large and hard after a high-temperature dyeing process. On the other hand, if the residual shrinkage ratio exceeds 45%, there is a problem that the shrinkage characteristics of the yarn are excessive, and the fabric is hardened due to excessive shafts after the fabric is manufactured after the dyeing process.

Hereinafter, each of the first yarn and the second yarn included in the mixed yarn according to the present invention will be described in detail.

First, the first yarn will be described.

The first yarn may be a fiber capable of exhibiting a difference in dyeing density on the fabric after dyeing, and may be used without limitation in the case of a polyester yarn having a monoclinic non-uniformity in fineness. Unevenness of the monosaccharide fineness means that the homogeneity degree (U) is not good and may mean a posture to be used in the art.

The material of the first yarn may be any one or more of fibers selected from the group consisting of polyethylene terephthalate, polytrimethylene terephthalate and polybutylene terephthalate, but is not limited thereto. In the case of polyethylene terephthalate, polyethylene terephthalate, for example, may be a sulfonic acid metal salt as an acid component or a modified polyethylene terephthalate further containing components such as isobaride as a diol component in order to improve the heat resistance, in addition to the main repeating units of ethylene and terephthalic acid.

In addition, the first yarn may have a fineness of 30 to 200 denier and a number of strands of 24 to 144, but the present invention is not limited thereto. However, when the fineness of the first yarn is less than 30 denier, the difference in dyeing density after the desired dyeing may be weak, and when the fineness is more than 200 denier, .

According to a preferred embodiment of the present invention, the first yarn may satisfy the following conditions (5) and (6).

(5) elongation of 50 to 100%, and (6) non-water shrinkage of 20 to 40%.

Firstly, as a preferable condition (5) for the first yarn, the elongation may be 50 to 100%, and thereby, a further improved dyeing tint difference can be expressed. When a stretching process is conducted to orient the polymer in the fiber after it is usually radiated, the mechanical strength of the fiber may be increased but the elongation may be reduced. However, such an increase in the orientation of the polymer in the fibers may not make the fineness of the desired mono-yarn uneven, and in the case of the fibers in which the fineness of the mono-yarn is not uneven, the dyeing does not generate a salt after the dyeing, I can not. Accordingly, the yarn can be produced by spinning in a state in which the orientation in the fiber is suppressed, so that the elongation can be 50% or more, and the yarn can exhibit a further enhanced dyeing shade difference after dyeing. However, when the elongation is too high, the strength of the first yarn is improved through the second yarn which will be described later, so that the strength and elongation of the yarn are similar or higher than those of the fibers exhibiting the difference in the conventional dyeing density. It is advantageous in that it can exhibit even more excellent dyeing and tinting difference. However, when the elongation is more than 100%, the strength of the yarn is weak, so that it may be difficult to produce the yarn with blended yarn.

Next, as a preferable condition (6) for the first yarn, the non-water shrinkage ratio may be 20 to 40%. If the non-water shrinkage ratio exceeds 40%, there may be a problem that the fabric is shrunk or shrunk during the high-temperature dyeing process, and if the shrinkage ratio of the non-water shrinkage is less than 20%, such a yarn is produced by high stretching ratio and heat fixation And thus there is a problem in that it is not possible to develop a natural jade tea.

Next, the second yarn to be mixed with the above-mentioned first yarn will be explained.

The second yarn may be a polyester twist yarn having a monosan fineness of 0.3 to 1.2 denier, and may serve to complement the strength of the first yarn and prevent the fabric from being hardened after being dyed.

The second yarn includes a polyester false yarn having a monosaminate fineness of 0.3 to 1.2 denier. The monosan filament yarn has a fineness of 1 denier or less to prevent the first yarn from being hardened by a high-temperature dyeing process So that the fabric can express a more smooth touch feeling. More preferably, the monosaminate fineness of the second yarn may be in the range of 0.5 to 1.0 denier, so that a more excellent touch feeling of the fabric can be exhibited. If the monosaccharide fineness of the second yarn is less than 0.3 denier, such a yarn is difficult to produce at the current level of technology, and even if it is produced, the productivity is poor. Because of the low mono fineness, There may be an increased problem. In addition, if the monosaminate fineness of the second yarn exceeds 1.2 denier, the monosan fineness of the false-twist yarn after the production of the mixed yarn is too high, so that the soft touch deteriorates, Can be.

On the other hand, the second yarn may be a polyester false yarn, and it has an advantage of being excellent in stretchability compared to a general filament yarn through a false twist and having a soft touch.

The second yarn may have a fineness of 20 to 450 denier and a strand number of 24 to 432, but the present invention is not limited thereto.

According to a preferred embodiment of the present invention, the second yarn may satisfy the following conditions (7) and (8).

(7) a shrinkage ratio of 5 to 20%, and (8) a shrinkage percentage of 20 to 60%.

As the condition (7), the second yarn can satisfy the residual shrinkage rate of 5 to 20% and the condition (8) to satisfy the residual shrinkage ratio of 20 to 60%, and through this, And it is possible to prevent hardening of the fabric by suppressing the excessive shrinkage phenomenon that occurs during the final fabric processing through high expansion and contraction characteristics. If the above range is unsatisfactory, there is a problem that the fabric is hardened due to the shrinkage phenomenon that occurs when the final fabric is processed using the filament yarn, so that the present invention may not be suitable for the filament yarn exhibiting the desired properties.

In addition, the second yarn may have a strength of 4 to 5 g / de 'as a condition (9), and thus the strength of the mixed yarn can be further improved. Particularly, when the first yarn exhibits a natural dyeing shade difference There is an advantage that the strength that can be lowered can be supplemented by the second yarn.

The blended yarn according to the present invention can be produced through the following production process. However, the present invention is not limited to the following production method.

The mixed yarn according to the present invention is a method for producing a mixed yarn comprising a first yarn and a second yarn, the method comprising the steps of: (1) a polyester yarn in which the monosaminate fineness is uneven by the first yarn, Preparing a polyester polycrystalline yarn of 0.3 to 1.2 denier; And (2) mixing the first yarn and the second yarn; . ≪ / RTI >

In the step (1) according to the present invention, a step of preparing a polyester yarn having a non-uniform monosaccharide fineness with the first yarn and a polyester false yarn having a monosan fineness of 0.3 to 1.2 denier as the second yarn are carried out .

First, a step of preparing a polyester yarn in which the monosaccharide fineness is nonuniform with the first yarn will be described.

The description of the polyester yarn itself having a mono-filament fineness unevenness is the same as that described above, so that a detailed description thereof will be omitted, and a method of producing a fiber in which the above- Any of which can be employed.

Preferably, however, 1-1) a step of melting and spinning the polyester polymer; And 1-2) stretching the spun polyester fiber between a first godet roller having a speed of 1500 to 2200mpm and a stretching temperature of 30 to 70 ° C and a second godet roller having a speed of 3000 to 4000 mpm and a heat treatment temperature of 90 to 130 ° C A first yarn may be produced.

FIG. 1 is a schematic view showing a process for producing a polyester yarn in which mono-filament fineness is nonuniform according to a preferred embodiment of the present invention, wherein a polyester polymer having an intrinsic viscosity of 0.5 to 0.9 dl / g is melted at 230 to 280 ° C And then discharged into the circular cross-section spinneret 2.

In this case, the diameter of the polymer discharge hole may be 0.16 to 0.36 mm, preferably 0.20 to 0.30 mm in the case of the circular cross-section spinneret, but the present invention is not limited thereto. Depending on the fineness of the desired first yarn, . Further, the shape of the hole of the spinneret may also be radiated through a hole of a non-circular shape in accordance with the purpose.

The spun polyester fiber can be cooled by the cooler (1). At this time, the wind speed of the cooler 1 is set to 0.30 to 0.70 m / sec, the temperature of the cooling air is set to be in the range of 16 to 25 占 폚, preferably the air velocity of the cooling air is set to 0.4 to 0.6 m / sec, It is good to do. Thereafter, the quenched filament may be supplied with the oil by the oil supply device 3, and the oil supply may be performed by the oil injection method or the oil roller method, and either method may be used.

Thereafter, the stretching process may be performed. At this time, the stretching process is performed through the first godet roller 4 and the second godet roller 5. The temperature of the first godet roller 4 may be in the range of 30 to 70 占 폚 and the speed may be 1500 to 2200 mpm. If the temperature of the first godet roller 4 is 30 DEG C or lower, there is a problem of being cut at the time of stretching. When the temperature is 70 DEG C or higher, hot rolling occurs, which makes it difficult to obtain the posture effect as in the present invention. If the speed of the first godet roller 4 is 1500 mPa or less, the spinning speed is too slow to cause a problem in the production process and the productivity is lowered. When the speed is 2200 mpm or more, the stretching effect is increased, There may be a problem that the appearance of the jade tea is remarkably lowered.

The temperature of the second godet roller 5 is ideally 90 to 130 DEG C. When the temperature of the second godet roller 5 is 90 DEG C or lower, the thermal stability becomes unfavorable. When the temperature of the second godet roller 5 is 130 DEG C or higher, There is a problem that the posture effect is reduced. When the stretching ratio is less than 1.4, there is a problem that the posture effect is weak and the stretching ratio is too low, so that the strength is lowered. When the stretching ratio exceeds 2.0, there arises a problem that the posture effect is reduced.

Next, a step of preparing a polyester false yarn having a monosamtha fineness of 0.3 to 1.2 deniers as the second yarn will be described.

The polyester false-twist yarn itself having the monosaccharide fineness of 0.3 to 1.2 denier is the same as that described above, so that a detailed description thereof will be omitted, and it is to be understood that the polyester yarn can be manufactured from fibers having desirable physical properties satisfying the above- Any method that can be used can be employed.

On the other hand, in the case of the false yarn in which the monosan fineness satisfies 0.3 to 1.2 denier, the second yarn is not limited in its manufacturing method. The polyester resin can be produced through melting and spinning after the polyester resin is melt-spun by a known production method, and the polyester resin can be produced by composite spinning together with the polyester resin as another method, And then flaking the obtained isobutane. If the monofilament yarn of the second yarn and the twin yarn satisfying the properties according to a preferred embodiment are used, a known method can be adopted, and a detailed description of the manufacturing method will be omitted.

Next, in step (2) according to the present invention, a step of mixing the first yarn and the second yarn prepared by the above-mentioned method is performed.

The mixed fibers may be mixed with each other without interrupting any of the above-mentioned different kinds of fibers and making the other one a superfine fiber.

The specific method of the cross-linking may be performed by air entanglement preferably with a sublimation speed of 200 to 900 mpm, and more preferably by air entanglement with an air pressure of 1.0 to 4.0 kg / cm2. If air pressure is less than 1.0 kg / cm < 2 > If 4.0 Kg / cm < 2 >, air loops are generated, and the quality of the blended yarn is deteriorated.

Meanwhile, the present invention includes a fabric including the horny yarn according to the present invention described above. The term " fabric " used in the present invention is meant to include both fabric and knitted fabric.

First, the fabric may be a fabric that has been weaved using at least one of warp yarns and weft yarns according to the present invention.

The weaving may be performed by any one method selected from the group consisting of plain weave, twill weave, water weave, and double weave.

If the plain weave, twill weave, and water weave are three-dimensional tissue, the specific weaving method of each of the three-dimensional tissue is determined by a conventional weaving method, and it is possible to modify the tissue based on the three- There are, for example, changing jobs, changing jobs, changing jobs, changing jobs, changing jobs, non-working jobs, and twisting jobs. .

The double yarn is a method of weaving a fabric in which either one of warp yarns or weft yarns is doubled or both yarns are doubled. The specific method may be a conventional double yarn weaving method.

However, the present invention is not limited to the base fabric of the above-mentioned fabric, and is not particularly limited in the case of the warp yarn density in weaving.

Also, the fabric may be a knitted fabric including a horny yarn as a yarn. The knitting can be performed by a method of stitch knitting or knitting, and a specific method of stitch knitting and knitting can be performed by a conventional method of stitch knitting or knitting.
