BACKGROUND OF THE INVENTION 1. Field of the Invention [0001]

The present invention relates to a douvable fabric for summer use mainly used for clothes and bedding in summer, and a method of producing the same. More particularly, the present invention relates to a douvable fabric for summer use, which comprises a first warp yarn as a polyester yarn and a second warp yarn completed through an interlacing process The present invention relates to a douvage fabric for summer use, which is obtained by mixing natural fiber yarn and synthetic fiber yarn, and a method for producing the same.

As the temperature is rising in summer due to global warming, the demand for cooling energy is increasing day by day, so fabrics for cold fabrics that are excellent in cold sensation, quick drying and comfort are attracting attention.

As a conventional textile material for summer use, hemp fiber fabrics have been used in many cases, but they have been problematic in that they are rough and expensive, and in the case of cotton fiber fabrics or synthetic fiber fabrics, there is a problem of lack of quick sensibility .

In order to overcome such disadvantages, a variety of techniques have been developed, for example, synthetic fiber fabrics in which inorganic particles are dispersed in synthetic fibers to improve ultraviolet shielding effect, or fabrics woven with synthetic fibers in a cross-section are used as clothing materials for summer .

However, these techniques have been developed with a focus on functionality, so that the development of a technology that meets the beauty of the fabric is still insufficient.

In particular, due to the free trade agreement (FTA), the domestic textile market has been replaced by low-priced imports in a price-competitive manner, and the domestic textile market crisis is intensifying. Therefore, in order to resolve the domestic textile market crisis, Development of a high-quality fabric having a good fit with the visual effect of the fabric as well as the functionality of the fabric is urgently required.

BRIEF DESCRIPTION OF THE DRAWINGS Fig. 1 is a front view showing a preferred embodiment of the present invention. Fig.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Reference will now be made in detail to the preferred embodiments of the present invention, examples of which are illustrated in the accompanying drawings.

FIG. 1 is a front view showing a preferred embodiment of the present invention. In the present invention, a dovish fabric for summer use and a method for producing the same are provided with a first warp yarn as a polyester yarn and a second warp yarn as a finished yarn after interlacing the stretch yarn and the embroidery yarn By using the natural fiber yarn and the synthetic fiber yarn in combination, the first and second inclined yarns improve the touch feeling and the ventilation of the fabric, and the weft yarn has the two-tone color, Element.

For this purpose, the present invention prepares a finished first warp yarn through twist yarn twisted at 800-1200 t / m for polyester yarns of 75-150 denier / 36-192 filaments.

1, the first warp yarn and the weft yarn are fed to the base layer 10 and the pattern layer 20 to form a weft yarn, .

As shown in FIG. 1, the first warp yarn and the weft yarn are fed to the base yarn 10 and the weft yarn, Weave the dough fabric into the layer 20.

Here, the twisting process in which the first warp yarns are twisted at 800 to 1,200 t / m minimizes the rise of the nap onto the surface of the weft knitted fabric, thereby preventing the filling phenomenon and improving the quality of the fabric.

The reason why the twisting process is limited to the condition of 800 to 1200 t / m is that the phenomenon in which the feeling of repulsive elasticity is insufficient at the time of performing the twisting process to less than 800 t / m, To prevent the stretchability from being lowered during the execution of the twisting process.

The natural fiber yarns of the weft yarns are used in combination of any one or more of natural fiber yarns of 30 to 50 yarns, bamboo yarn of 30 to 50 yarns, and artificial yarn of 75 to 150 denier. The synthetic yarns of the weft yarns are polyester 75 to 150 denier / 36 to 288 filaments.

Here, cotton is a material widely used for underwear and bedding because it absorbs moisture well, is comfortable to wear, is soft and resistant to friction, and has advantages of durability and good ironing ability and not being damaged even when boiled.

Bamboo is chemically hydrolyzed by alkaline hydrolysis of bamboo raw material, and purified through multiple bleaching processes. It is made by injecting into fine pores. It does not detect any harmful components in the human body, so it is eco-friendly and has antibacterial and deodorizing function. So that the sweat can be quickly absorbed and discharged to the outside, so that a pleasant feeling can be exhibited.

Anthrax refers to a thread made by joining a series of long continuous fibers in a thread of a fiber (cellulosic), a chemical fiber (rayon, cupra, acetate), and is excellent in breathability and hygroscopicity, It is easy to ventilate without touching to the body because it is fast, and the skin touch is very cool, pleasant and easy to wash, and it is woven so that it can feel cooler feeling when used as the weft of the present invention.

DTY yarns made of polyester 75 ~ 150 denier / 36 ~ 288 filament are similar in thickness to the first warp yarn, so that the warp pattern is clearly realized along with the first warp yarn to improve the quality of the weft fabric, To be effective.

In addition, polyester DTY yarn is twisted after stretching, twisted and twisted yarn is set in the process of loosening to maintain its shape even in conditions such as heat or cooling, so that it is more soft than normal filament yarn and excellent Beddings and summer fabrics.

On the other hand, repeatedly sending the natural fiber yarn and the synthetic fiber yarn to the weft yarn is intended to improve the price competitiveness of the fabric by reducing the number of the natural fiber yarn having the advantages of the natural fiber yarn and relatively expensive.

In addition, since the weft yarn is repeatedly fed from the natural fiber yarn and the synthetic fiber yarn, the melange effect can be expected by implementing the two-tone color on the dobby fabric surface, so that the viscose dobby fabric can be woven.

That is, natural fiber yarn is used for dyeing by using natural dye, and synthetic fiber yarn is used for dyeing by using chemical dye.

Accordingly, the dobby cloth of the present invention may be subjected to two dyeing processes using natural dyes and chemical dyes, or may be dyed using any one of natural dyes and chemical dyes in a color comparable to that of natural fiber yarns and synthetic fiber yarns The two-tone color can be realized by performing the dyeing process. This can be done by selecting and choosing through convenience and productivity of work.

Here, in order to maximize such effects, it is preferable that the natural fiber yarn and the synthetic fiber yarn are respectively fed in a ratio of 1: 1 to 3 in number of strands.

On the other hand, in order to further improve the quality of the doughy fabric, the first warp yarns were interlaced with a stretch yarn made of polyester 45 to 55 denier / 48 filaments and a high-build yarn made of polyester 25 to 35 denier / 24 filaments, A second warp yarn completed through a twisting process in which the twist is performed at ~ 1200 t / m may be used.

The second inclination is subjected to an interlacing process between a stretching yarn and a high-stiffness yarn. The interlacing process causes the airflow to vertically collide with the filament axis and simultaneously generate turbulence parallel to the filament axis, And at the same time randomly mixing.

That is, the second slope is subjected to the interlacing process by interlocking the stretch yarn with the examination of the high-stature yarn, and the second slope subjected to the interlacing process is fixed and the stretch yarn is stretched on the high- It is possible to produce a fabric of good quality which improves the breathability and drying efficiency by minimizing the slipping phenomenon of the base layer 10 except for the pattern layer 20 while improving the comfort of the fabric by causing the elasticity of the fabric.

Further, unevenness is generated on the second inclined surface by the entangled stretch yarn, and the weft yarn is stably woven with the weft yarn mixed with the natural yarn fibers through the twisting process in which the second warp yarns are twisted at 800 to 1200 t / m, The phenomenon is minimized, and the touch feeling of the fabric is also improved.

The interlacing conditions of the second warp stretch yarn and the high stiff yarn are 2 ~

And at a treatment rate of 100 to 6000 m / min at a pressure of 5 kg / cm2.

In addition, the second warp yarn after interlaced processing is stained with a rapid dyeing machine maintained at 120 DEG C to adhere to the interlaced form.

Here, the first and second warp yarns of the present invention are preferably weaved using the first warp yarn when price competitiveness or productivity is given priority, and when the quality is preferentially taken into consideration, It is preferable to weave it.

However, if the first warp yarn and the second warp yarn are appropriately used at a ratio of 1: 1 to 2, the dough fabrics can be produced which can satisfy both productivity and quality.

Meanwhile, there are two manufacturing methods of the dobby fabric having the above-described construction, in which the first inclination and the second inclination are separately performed.

A method of producing a dope fabric using a first warp yarn comprises the steps of preparing a first warp yarn finished through a twisting process in which yarns of 75 to 150 denier / 36 to 192 filaments of polyester are twisted at 800 to 1200 t / m .

In addition, a natural fiber yarn mixed with one or more of any one or more of 30 to 50 cotton yarns, 30 to 50 yarn bamboo yarns, 75 to 150 denier yarn, and DTY sine synthetic fibers having a polyester 75 to 150 denier / 36 to 288 filaments And preparing a weft yarn.

In addition, the first warp and weft yarns may be weaved so that the weft yarns consisting of the base layer 10 and the pattern layer 20 are woven, wherein the natural fiber yarns of the weft yarns and the synthetic fiber yarns are each in a ratio of 1: And sending and weaving.

The dyed fabrics woven with the first warp yarns and the weft yarns are subjected to a primary dyeing process performed at 110-130 ° C for 5-15 minutes, a secondary dyeing process performed at 75-95 ° C for 25-35 minutes, And a third dyeing step performed at 65 DEG C for 35 to 45 minutes.

The reason why the dyeing process is performed by dividing the dyeing time at a high temperature to a low temperature is that the density of the first warp yarns woven after finishing the dyeing process is tightened So as to improve the warp of the fabric.

In addition, the step of performing the tentering process at a speed of 30 to 500 m per minute by the tenter machine in which the temperature is maintained at 80 to 90 ° C in a state where the dovi fabric having the dyeing process is opened at 20 to 50 m is included.

Since the tenter process is performed in a state where the tenter process is performed at a relatively low temperature in a state where the tenter process is performed at a relatively low temperature as compared with the tenter process performed on general fabrics, productivity can be improved as well as energy can be reduced. So that the softness of the surface is prevented from being drastically reduced, thereby maintaining the tension and density of the fabric at a constant level.

A method of manufacturing a dope fabrics using a second warp yarn comprises interlacing a stretch yarn made of polyester 45 to 55 denier / 48 filaments and a high-build yarn made of polyester 25 to 35 denier / 24 filaments, And a step of preparing a finished second warp yarn through a twist yarn process in which twisting is performed.

In addition, a natural fiber yarn mixed with one or more of any one or more of 30 to 50 cotton yarns, 30 to 50 yarn bamboo yarns, 75 to 150 denier yarn, and DTY sine synthetic fibers having a polyester 75 to 150 denier / 36 to 288 filaments And preparing a weft yarn.

The second warp yarn and the weft yarn are weaved so that the weft yarn consisting of the base layer (10) and the pattern layer (20) is woven, and the natural fiber yarn of the weft yarn and the synthetic fiber yarn are weighed at a ratio of 1: And sending and weaving.

Also, the dyed fabrics woven with the second warp yarns and weft yarns are subjected to a primary dyeing process performed at 110 to 130 ° C for 5 to 15 minutes, a secondary dyeing process performed at 75 to 95 ° C for 25 to 35 minutes, And a third dyeing step performed at 65 DEG C for 35 to 45 minutes.

The reason why the dyeing process is performed by dividing the dyeing time at a high temperature and the low temperature is to prevent the curing of the fabric due to high heat, To improve the ventilation and elasticity of the portion processed to be woven in the second warp yarn and to maintain the densities of the second warp yarns and weft yarns after finishing the dyeing process so as to improve the weavability of the fabric.

In addition, the step of performing the tentering process at a speed of 30 to 500 m per minute by the tenter machine in which the temperature is maintained at 80 to 90 ° C in a state where the dovi fabric having the dyeing process is opened at 20 to 50 m is included.
