The present invention relates to a method for producing a composite functional fabric having different functionalities on the front and back sides of the fabric and the fabric.

In more detail, the fabric has a new concept of high quality with different properties on both sides by maintaining different functions such as water absorbency on the back of the fabric or maintaining functional properties to complement the above function, and water repellent on the surface. To provide a product.

Generally, it is easy to give only one function such as water repellency to a single layer of fabric, but it is very difficult to simultaneously express other complex functions at the same time.

For example, coexisting extremely contradictory two qualities of water repellency and water absorbency has been difficult for the prior art.

In other words, in order to impart functionality such as water repellency to the fabric, it is a means of immersing the fabric to be treated in a functional solution such as a water repellent, and in the process, water repellent penetrates to the front and back and inside of the fabric to impart only one function to the entire fabric. This is because you have to.

However, conventionally, unlike the method of the present invention, a means for simultaneously imparting water repellency and water absorption has been provided.

That is, a method of imparting water repellency through surface modification by low temperature plasma discharge of the surface of the fabric and a method of imparting water repellency by treating the surface of the fabric with a spray method on the surface of the fabric are provided.

In the case of the above method, it is difficult to achieve the desired level of performance fundamentally, and there are problems such as instability of quality and reproducibility due to limitation of processable fabric and difficulty of setting processing conditions, problems such as poor quality, excessive loss, and manufacturing cost burden. It was difficult.

As another method, there is a method of bonding a two-ply fabric having water repellency and absorptivity with an adhesive, but this is different from the present invention, and the use is also limited.

The present invention is to solve the above-mentioned conventional problems, and has a different function on the surface and the back of a single layer of fabric, the method of producing a multi-functional fabric and the fabric so that the specific function can be exactly to the desired part of the fabric Its purpose is to provide.

In order to achieve the above object, the present invention forms a barrier coating layer on a side of the fabric with a material such as a filler, immersed the fabric in a functional aqueous solution having a water repellency-like function, and then heat-treated, washing the heat treated fabric with water By removing the coating layer, one side of the fabric is to maintain the properties of the fiber unique and at the same time the other side to be provided with a multi-functional fabric in which the functional holding layer of the functional aqueous solution is formed.

In carrying out the present invention, a barrier coating layer is formed of a material such as a filler on a surface to which the functional functional layer is applied to the composite functional fabric treated as described above, and the fabric is immersed in another functional aqueous solution and then blocked by heat treatment and washing with water. Removing the coating layer may impart the necessary functionality to both sides of the fabric.

If necessary by means of the above means, such functionality may be selectively provided in part, which may be appropriately selected and processed according to the needs and intended use.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 is a side configuration diagram of a general fabric 10 showing an untreated state fabric for manufacturing a multifunctional fabric of the present invention.

FIG. 2 shows that the barrier film layer 20 is formed on the one side 11 of the fabric 10 by being edged or coated, so that the barrier film layer 20 is formed only on one side 11 of the fabric 10 and then dried.

3 is a functional imparting layer 30 only on the other side 12 in which the barrier layer 20 is not formed by immersing the fabric 10 in which the barrier layer 20 is formed only on one side of the fabric 10 in a functional aqueous solution. ) Is formed.

As shown in FIG. 3, the barrier film layer 20 is formed on one side 11 of the fabric 10, and the functional solution is fabricated by heat-treating the fabric 10 on which the functional retention layer 30 is formed on the other side 12. To the other side 12 of (10).

The heat treated fabric is washed with water in a washing tank sufficiently to remove the barrier film layer 20 formed on one side 11 of the fabric 10, and then dried, and the other side of the fabric 10 as shown in FIG. 12) it is possible to provide the multifunctional fabric 40 in which the functional retaining layer 30 remains.

In the practice of the present invention, the concept of the fabric can be used, such as woven fabrics, knitted fabrics and non-woven fabrics.

The material of the barrier coating layer 20 applied to one side of the fabric 10 uses natural paints, processed paints, synthetic paints, etc., and the foils are uniformly inlaid or coated on only one side of the fabric 10, but the cross section of the fabric is applied. It is important to properly penetrate only a few areas.

The function of the barrier coating layer 20 is to prevent the functional aqueous solution from penetrating into the portion where the barrier coating layer 20 is formed during the functional solution immersion process, which is a post-process, and is easily removed from the fabric 10 when washing the barrier coating layer 20. The part that has been applied is exposed to restore the original function of the fabric.

In addition, in order to properly penetrate the barrier coating layer 20, that is, the material into the fabric 10, the viscosity is adjusted according to the conditions of the fabric 10 such as the type and thickness of the fabric, but the viscosity is in the range of approximately 500 to 70000 cps. Use appropriately within.

At this time, since the viscosity of the paint used as the barrier coating layer 20 is 500 cps or less, it is difficult to maintain its own viscosity, so that the barrier coating layer 20 applied to one side 11 of the fabric 10 is the other side 12. There is a risk of penetrating until the penetration of the functional aqueous solution that gives the functionality is limited, causing problems.

Contrary to the above, if the viscosity is more than 70000 cps, the viscosity is too strong, which makes it difficult to work, and it is difficult to penetrate into the fabric 10 surface, so that the original function recovery of one side 11 of the fabric 10 is completed. It is not desirable because problems arise.

Means for forming the barrier film layer 20 on the fabric (10) can be used in a variety of applications, such as the commonly used method, such as the coating method, and when the barrier film layer 20 is formed on the fabric 10, the blocking Allow the coating layer 20 to dry.

The functional holding layer 30 treated on the other side 12 of the fabric 10 varies in functionality depending on the function of the functional aqueous solution for forming the functional holding layer 30.

As an example of the functional aqueous solution used in the above can be selected a water repellent, and the type of water repellent used here can be applied to various types of water repellents, such as wax emulsion type, metal complex salt type, silicone type, ball type, and the use of the fabric What is necessary is just to use suitably according to a kind and thickness.

The condition of the water repellent used in the present invention is in accordance with the normal working standards, the concentration of the water repellent is 2% OWS to 10% OWS aqueous solution of about 70% to 100% of the weight of the fabric (pick-up) of the fabric type, uses, etc. Please choose according to your use.

The general method of the means for forming the functional aqueous solution of the above conditions on the other side 12 of the fabric 10, the barrier film layer 20 is formed can be selected by dipping method, in addition to the above method may be a spray method.

The immersion or spray can be conveniently handled in the equipment and apparatus installed at the inlet of the tenter for conventional fabric heat treatment.

As described above, by heat-treating the fabric formed with the barrier film layer 20 and the functional retaining layer 30 on both sides of the fabric 10, the functional holding layer 30 is fixed to the other side 12 of the fabric 10 At this time, the heat treatment condition is a heat treatment for about 20 to 180 seconds at 120 ~ 180 ℃, the above conditions are treated by adjusting according to the type and nature of the fabric.

In order to minimize the change in functionality, washing of the heat-treated fabric is carried out in a normal temperature washing tank and a hot water washing tank of about 50 to 70 ° C. without using a separate washing agent, and at this time, to form the barrier film layer 20. The washing conditions are adjusted according to the type of filler used and the degree of penetration.

The washed fabric is dried in a conventional manner to complete the manufacture of the multifunctional fabric 40 to be provided in the present invention.

In manufacturing the multifunctional fabric of the present invention, it may be treated as shown in Figs.

That is, as described above, in the state in which the functional holding layer 30 is formed on the other side 12 of the fabric 10, the barrier coating layer 20 'by using a paint on the functional holding layer 30 as shown in FIG. ) Is superimposed, and in the above state, another functional holding layer 30 'is formed by infiltrating a functional aqueous solution having different functionalities on one side 11 as shown in FIG. Drying may be performed to form functional retaining layers 30 and 30 'having different functions on both surfaces as shown in FIG.

As another example, as shown in Figs. 9 to 12, partial functionality may be imparted to one side 11 of the fabric 10. Figs.

That is, as shown in Figure 10, the one side 11 of the fabric 10, the barrier coating layer (20 ") using the paint is partially formed in a printing method, and the fabric 10 is immersed in a functional aqueous solution and As described above, the functional retaining layer 30 " is formed in the remaining portions except for the barrier coating layer 20 ", and then the composite functional fabric 40 can be manufactured by heat treatment, washing with water, and drying.

In imparting functionality on the fabric by the method of the present invention, it is desirable to ideally select the fabric according to the purpose of obtaining the functionality.

As an example, one side 11 is intended for the purpose of excellent absorbency, the other side 12 is to provide a textile product for the purpose of water repellent function, when weaving of the fabric, the exposure of the fiber having excellent absorbency on one side In this case, it would be more effective for the functional expression to select a fabric with a higher exposure to the synthetic fiber yarn having a relatively poor absorbency on the other side 12.

This may be selected and used according to the purpose and use of the functionality.

Hereinafter, an embodiment of the present invention will be described.

<Example 1>

The fabric 10 is prepared with the warp yarn dyed 100% nylon, 100% cotton weft, 215 grs / yd and tissue 1/2 twill fabric.

As a material for forming the barrier coating layer 20 on the fabric 10, a mixture adjusted to a carboxymethyl cellulose (CMC) solid 10% OWS and adjusted to a viscosity of 10000 cps is prepared.

Using a printing printing machine on the one side 11, the cotton yarn is exposed a lot from the top fabric 10 uniformly in the front of the paint of about 150gr / yd and dried to form a barrier film layer (20).

The fabric 10 was immersed in a functional solution of 3% ows of fluorine-based water repellent, and then picked up by 80% owf and heat treated at 160 ° C. at a rate of 40 m / min for 25 seconds to maintain a water-repellent layer having a water-repellent function on the other side 12 ( 30) is formed.

The fabric 10 treated as described above was washed in a cold and hot water bath at 25 ° C. and 60 ° C. to wash and remove the barrier coating layer 20 that was inlaid on one side 11 at a speed of 80 m / min at 120 ° C. Drying for 10 seconds was completed the manufacture of the multifunctional fabric 40 to be obtained in the present invention.

<Example 2>

The fabric 10 is prepared with the warp yarn dyed 100% nylon, 100% cotton weft, 280 grs / yd, and tissue 2/2 Twill.

The fabric 10 was treated in the same manner as in <Example 1> to complete the composite functional fabric 40.

<Example 3>

The fabric 10 is prepared in a state where the warp yarn is dyed 100% polyester, 100% cotton weft, 265 grs / yd, and 5 tissues Satin fabric.

The fabric was treated in the same manner as in <Example 1> to complete the composite functional fabric 40.

Comparative Example 1

By using the same fabric used in the <Example 1> by immersing in a functional aqueous solution having a water-repellent function in the conventional immersion formula to prepare a water-repellent functional fabric.

Comparative Example 2

Using the same fabric used in <Example 2>, a water-repellent functional fabric was prepared by immersing in a functional aqueous solution having a water-repellent function in a conventional immersion method.

Comparative Example 3

Using the same fabric used in the <Example 3> by immersing in a functional aqueous solution having a water-repellent function in the conventional immersion formula to prepare a water-repellent functional fabric.

Water repellency and water absorption were measured and evaluated for the fabrics prepared in the examples of the present invention and the conventional comparative example, and the results are shown in Table 1.

TABLE 1

※ How to measure water repellency

Test Method: Spray Method (KS K 0590)

The water repellency of Table 1 is the result measured by the water repellency measurement method, the water absorption was not measured because there is no test method and standard, but the sensory evaluation was performed.

In Table 1, the other side water repellency was not particularly different between the Example and the comparative example.

In the evaluation of Table 1, the other side water repellency was evaluated to be equally excellent in the Examples and Comparative Examples, but the one side absorbency showed the opposite evaluation.

This means that in the case of the comparative example, the extremely poor one side absorbency means that the water repellency is good, that is, one side and the other side have the same water repellency.

On the other hand, in the case of the embodiment, the absorbency of one side is good, and it can be seen that the other side water repellency and the one side absorbency coexist on one layer of fabric.

Therefore, forming a coating material or barrier coating layer on only one side of the fabric which must maintain absorbency with a specific viscosity of the coating material, and then immersing it in a functional aqueous solution, that is, a water repellent, to remove the barrier coating layer by washing with water, This makes it possible to produce excellent multifunctional fabrics that are dualized into water repellent and absorbent zones.

In addition, according to an embodiment of the present invention after forming a barrier film layer on one side of the fabric as a foil water-repellent treatment with a water repellent, and removing the barrier film layer can produce a composite functional fabric which is dual in water repellency and absorbency in a single layer of fabric In addition, various fiber materials, such as chemical fibers and natural fibers, can be easily applied to woven fabrics, knitted fabrics, nonwoven fabrics of the same concept or the like manufactured by a single or mixed, blended, teaching, etc. method, thereby exhibiting excellent composite functionality.

According to the present invention, as it is possible to impart complex functionalities in a single layer of fabric, by using the multifunctional manufacturing method of the present invention, Soil Resistant, Rapid Absorption and Evaporation of Sweat, Fire Retardant ), Anti-static (Anti-Microbial and Deodorizing), Perfume processing, such as a combination of functional fabrics can be produced a variety of complex functional fabrics.

As described above, the present invention uses a single layer of fabric to manufacture and use a multifunctional fabric having different functionalities on the surface and the back, thereby increasing the desire for a comfortable human body-friendly garment material such as sports, leisure, and health. And it is effective to be widely used as a high quality material.
