Description

TECHNICAL FIELD [0001] The present invention relates to a method for producing a functional fabric using a polyester yarn,

The present invention discloses a functional fabric using a polyester raw material and a manufacturing method thereof, and it is provided by a spinning process using a pigment rather than a production method by dyeing or processing using a dye, It is possible to maximize the antioxidant effect due to the functional material as well as to reduce the degree of dyes and to be able to maximize the antioxidant effect due to the functional material. Further, by mixing the original yarn with the fusion yarn, The present invention relates to a method for manufacturing a functional fabric using a polyester raw material that is configured to actively induce a material such as lining.

The polyester polymer obtained by adding carbon black during the polymerization reaction or the stage from the polymerization reaction to the fiber formation by the conventional method and the fabrics fabricated therefrom are inferior in dyability due to the red hue as compared with those after dyed with a black dye.

In addition, carbon black particles having high cohesiveness are dispersed finely in the polymer due to agglomeration of carbon black or poor dispersion of carbon black during the polymerization reaction to form coarse particles. As a result, clogging of the filter or rupture of filaments occurs in the spinning step, It is not preferable that the spinning pressure during spinning sharply increases or yarn is not stretched at the time of drawing, and the affinity with the polymer is small, so that the strength and elongation are decreased even after the fiber is produced.

Japanese Patent Publication Nos. 49-87 and 49-792 disclose the use of copper phthalocyanine green in order to remove the red hue and prevent agglomeration. In Japanese Patent Publications 35-835 and 35-78 Although the use of copper phthalocyanine blue has been disclosed, the polyester fibers produced by these disclosed methods did not block visible red tones.

As a solution to this problem, Japanese Patent Application Laid-open No. 60-45689 and U.S. Patent No. 3,992,218 disclose dope staining methods using tonicity concentrates. However, since the liquid colorant reduces the content of carbon black, There is another drawback that the carbon black content in the carbon black is lowered.

As a result, there is a demand for a more improved form of the decorating yarn having various functions such as antimicrobial action and a functional fabric with good dyeability.

On the other hand, there are knitting methods and weaving methods mainly used for fabric processing, and the double knitting method is a method in which loops are continuously supplied from knitting machines of one or more allotted gauges , And the weaving method is a method of knitting a fabric by sequentially inputting weft yarns and warp yarns into the warped yarns.

In this case, since the knitting method is mainly used for knitting a fabric having a low density of tissue such as a sweater or a knit, in order to obtain a fabric having a high density of tissue, such as a cloth or a lining fabric of a suit, Is generally used.

As a method for weaving a fabric to be used as a lining, there are a continuous thread type in which the weft thread is sequentially wound on a regular thread, and a fusing system in which a constant heat is applied to the warp thread and the weft thread.

To briefly describe a method of weaving a lining made of double continuous yarn, a weft yarn or two strands are wound on a warped yarn. However, the lining which is made of one strand or two strands of weft has a problem in that the texture is not strong and the shape of the lining is easily deformed. In addition, the lining made of the fusing method has a problem that when the heat is applied to the fabric as in the case of ironing, the shape of the lining is easily deformed and the width of the lining is reduced.

For example, Korean Patent No. 10-1440388 discloses a method of weaving a lining having a silk feel as in the present invention, and a method of weaving a staff member using a silk yarn and a polyester fused yarn.

However, all of the conventional weaving methods including the above-mentioned prior arts are to attach a specific material to the basic yarn and to simply modify the texture or texture of the lining or to simplify the weaving process. There is no solution for ultimate durability and shape change in use.

Disclosure of Invention Technical Problem [8] Accordingly, the present invention has been made in view of the above problems, and it is an object of the present invention to provide an improved type of fabric by adding a functional element to the original.

Another object of the present invention is to realize a more aggressive color by combining the original yarn and the fused yarn which are formed in a predetermined process, and to realize another color in the stretching process of the fabric.

Another object of the present invention is to provide a weave of silver warp and weft by separately processing warp and weft yarns while weaving warp yarns in a warp yarn in a warp yarn without warp yarns and weft yarns.

Further, according to the present invention, the number of strands of the weft is set so as to optimize the density of the lining when the weft is warped on the warped warp yarns to enhance the durability of the lining, and even when the initial quality of the fabric It is another challenge to provide for sustainability.

The yarn was stretched by applying heat at 180 DEG C to a bright yarn of 50 inches in width, which was manufactured by sieving at a width of 50 inches in a canonical beam. Thus, a yarn of 50 denier was obtained Fusing yarn as a main component.

For this purpose, a method for producing a functional fabric using the polyester raw material proposed in the present invention will be described.

90 to 95% by weight of a polyester chip, 3 to 5% by weight of a color master batch and 2 to 5% by weight of a functional master batch having an antibacterial function and a deodorizing function, A polyester yarn forming step of melting at a temperature of a melting point or higher and extruding and cooling through a spinneret and a polyester yarn of 85 denier, A warp weaving step in which a warp yarn of 50 denier is formed by applying heat of 180 DEG C to a braid having a width of 50 inches and a warp yarn of 50 denier is formed to give a warp yarn density of 4800 dots and a warp width of 45 inches, The yarn is folded from the right side to the left side based on the direction in which the weaving is performed, And a fabric dyeing step of dyeing the fabric formed through the warp weaving step and the weaving step with a refeed machine having a temperature of 130 ° C for 40 minutes and a step of adding the antistatic agent while heating the dyed fabric to the temperature of 190 to 200 ° C .

The target polyester yarn obtained in the step of forming the polyester raw yarn can maximize the degree of coloring or color expression due to the production method due to the spinning process. This is because the dyeing process using the dye, Radiation process.

In the above-mentioned priesthood stage, as is well known, the present invention is implemented as a yarn-fed yarn, and then the fabric is dyed while the fabric is dyed. In this configuration, not only the color of the original yarn but also the dyed fabric So that it is possible to realize a dual color or a more vivid and differentiated color.

That is, in the present invention, in addition to the color representation of the original yarn, one finished fabric is subjected to another color processing by using the original yarn to thereby cause the color of the original yarn to be expressed externally when the fabric is expanded or contracted, The color used in the fabric dyeing step is expressed externally, and the purpose of the present invention is to realize a variety of colors with a difference in degree of sharpness of color.

In the present invention, the functional masterbatch further comprises a predetermined functional masterbatch so that the antioxidant function can be imparted. Preferably, the functional masterbatch is formed from a sage extract obtained from a sage stem and leaf .

In the upper priesthood stage, inclining to warp at warp 450TM, warp density per warp weft is 95T, and weft density per warp weaving stage is 70T.

In the present invention, warp and weft yarns are twisted to form weft yarns, and the warp yarns are formed by heating two 180 DEG C to 200 DEG C rows of bright yarns having a width of 50 inches and made of 85 denier polyester yarns 50 denier bonded yarn and 90 to 95% by weight of a polyester chip, 3 to 5% by weight of a color master batch and 2 to 5 of a functional master batch having antibacterial and deodorizing function % Of the raw material is melted at a temperature equal to or higher than the melting point and extruded and cooled through a spinneret to obtain a polyester yarn.

In addition, the above-described three strands of weft yarn are woven in such a manner that they are twisted from the right side to the left side of the warp yarn, so that a natural feeling such as a silk lining can be utilized, and when ironing, the fabric can be well deformed. In addition to maintaining the original fabric properties for a long period of time after washing or drying, the addition of antistatic agents prevents static electricity from being generated.

1 is an image of a functional fabric constructed in accordance with a preferred embodiment of the present invention.

As shown in FIG. 1, the present invention is characterized in that since the raw materials obtained in the polyester raw material forming step are woven together, the density is very high and the material is made of the same material as the silk lining while maintaining the tactile and semi- do.

The weaving pattern for this is the same as shown in Fig. 2, and the details thereof are as follows.

The warp yarns are prepared by processing a bright yarn of 50 denier applied to Bright yarn at 180 ° C, and further prepare three yarn yarns to be used as weft yarns of the above yarn yarn. At this time, the yarn of the fused yarn used as the warp yarn is made of bright yarn of 50 inch width made of polyester of 80 to 90 deniers, and is formed by blowing a bright yarn at 180 to 190 DEG C to form a yarn of 50 denier . In addition, the fused yarn at this time is judged to have a slope number of 4800 densities at a width of 45 inches.

For example, a high temperature of 180 to 190 ° C, which is provided to Bright for obtaining such a fused yarn, is an optimum temperature for converting bright yarn composed of 80 to 90 deniers into fusion yarn of 50 denier, If the fusing yarn provided with the temperature is used, the material of the fabric is stiff and it is difficult to use as a lining. On the contrary, when the fusing yarn provided with a temperature over the allowable range is used, the thickness of the fusing yarn becomes too thin, And damage may occur.

As described above, it is natural that the separately prepared yarns are weaved by warp, weft and plain weave by a water jet loom, and that the weft yarns are twisted from right to left based on the weaving direction of the fabric. For reference, it is preferable that the weft-water loom is weaved at a speed of 70 m / s in proportion to the thickness of the fused yarn composed of 50 denier, and the processing is performed at a temperature of 180 ° C for fusion of the warp yarn.

The most important part of the weaving method of the fabric according to the present invention is that when the weft yarn is warped to warp yarns, the weft yarn yarns are composed of three yarns and proceed together along the yarn yarn path for warp yarns.

For example, a conventional weaving method, which combines economy and functionality, is divided into a method in which warp and weft yarns are fused to each other and a method in which weft yarns are processed in a warp yarn. However, the lining having one strand or two strands of weft yarns has a problem in that the strength of the fabric is not strong and the shape of the clothes is easily deformed. In addition, in the case of the lining made of the fusing method, And the width of the bridge is also reduced.

Accordingly, unlike the conventional method, the present invention provides a feeling of silk lining as well as a feeling of being strong against heat, so that the initial properties of the fabric can be maintained for a long period of time even after ironing and frequent washing and drying operations. In particular, when the weft is warped on warp yarns, the yarn strength is 440 ~ 460TM, which maximizes the feel of the silk lining and enhances the durability of the fabric.

As described above, setting the yarn endurance between warp and weft at 440 to 460TM is due to the ability to maintain the best fit between warp yarns composed of 50 denier yarns and weft yarns composed of 20 denier yarn. The durability of the fabric may be reduced or unwanted stretchability may be caused. On the contrary, if the allowable range is exceeded, the dense density at the time of weaving between warp and weft causes problems such as stiff fabric, .

As shown in FIG. 2, an oblique yarn for regulating the inclination of the present invention comprises yarns 1 to 8 in order, and yarns 1 to 2, 3 and 4, 5, 6 and 7, 8 are twisted in a twisted shape to each other.

For example, when the yarn No. 1 is moved from the left side to the right side, the yarn No. 2 crosses with the yarn No. 1 from the right side to the left side, and the yarn No. 2 is directed to the lower side of the yarn No. 1 Is passed. Then, the yarn No. 1 moved to the right is moved to the left side, and the yarn No. 2 on the left side is crossed again with the yarn No. 1 to the right side, where the yarn No. 2 is passed above the yarn No. 1. Due to the above-described twisted shape, an elliptical ring is formed between the first yarn and the second yarn.

In addition, yarns 3 and 4 are made in a direction symmetrical to the twisted form of yarns 1 and 2, and yarns 5 and 6 are wound in the same direction as the twisted yarns of yarns 1 and 2, And No. 8 yarn are performed in the same direction as the No. 2 and No. 3 yarns.

The weft yarns are led through the respective rings of the warp threads so as to form the elliptical rings as described above. The elliptical rings for guiding the entry of the weft yarns are arranged in the order of the first access roads 10, The second access road 20, and the third access road 30, as shown in FIG.

The upper yarn is passed three yarns per each entry, and the form in which the yarn passes through the elliptical ring first goes up the first yarn of the first entryway 10 and passes downward of the second yarn, The yarn enters the lower direction of the yarn and passes the yarn in the upper direction of the fourth yarn. The yarn passed through the yarn No. 4 enters the upper side of the yarn No. 5, passes through the lower side of the yarn No. 6, enters the lower side of the yarn No. 7 again, and passes the yarn in the upper direction of the No. 8 yarn.

Further, in the form in which the weft passes through the second runway (20), the yarn enters under the first yarn and passes in the upper direction of the second yarn, and again enters the upper direction of the third yarn, It passes. The weft yarn passed through the yarn No. 4 enters the lower side of the yarn No. 5 and passes through the upper side of the yarn No. 6, and again enters the upper side of the yarn No. 7 and passes through the lower side of the No. 8 yarn. (10) and pass therethrough.

In addition, when the weft passes through the third entryway (30), the yarn enters the upper direction of the yarn No. 1 and passes downwardly of the yarn No. 2, again enters the lower side of the yarn No. 3 and passes through the upper side of the No. 4 yarn do. The yarn passed through the yarn No. 4 enters the upper side of the yarn No. 5 and passes through the lower side of the yarn No. 6 and again enters the lower side of the yarn No. 7 and passes the yarn in the upper direction of the No. 8 yarn, (Not shown), but it is natural that the fourth entry ramp is continuous with the second ramp 20 in the same direction.

In the above procedure, the weft yarn composed of three yarns and a warp yarn composed of 50 denier yarns is weighed at a speed of 70m / s and a temperature of 180 ° C through a water jet loom, while the density of the fabric is 96T Densities and weights with a weft density of 70 T are offered as excellent fabrics.

The fabric is then dyed with a feeder machine, and the feeder machine is preferably dyed at a temperature of 120-140 ° C. for 40 minutes.

The reason for using the above temperature and time is that when the slope is coated with the fused silica at a temperature of 180 ° C, the temperature can be dyed in a range that does not damage the coating, and the density is 96T per inch This is because the dyeing liquid can penetrate the fabric with the weft density of 70T most effectively.

As the dyeing process progresses sequentially, the fabric provided is again processed through a water jet loom, wherein the water jet loom is processed at a speed of 55 m / s and a temperature of 190 to 200 ° C, Prevent static electricity.

According to the present invention, it is possible to maximize the antioxidant effect by adding a functional element to the raw cotton yarn, and to provide the raw cotton yarn and the fusing yarn in a predetermined process. Thus, It is possible to realize another color in the process of stretching.

In addition, since the warp yarn and the weft yarn are individually processed while weaving the weft yarn in a manner that weft yarns are warped on the warp yarn without warp and weft yarns mutually fused, the present invention provides the texture of silver yarn lining, The durability of the lining is enhanced by setting the number of weft threads so as to optimize the density of the lining so that the original quality of the fabric can be maintained even in the case of external interference such as washing or drying.
