DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a moisture-absorbing and quick-drying fabric according to a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

As shown in FIG. 2, the moisture-absorbing and quick-drying fabric of the double weave structure according to the present invention comprises a backing fabric layer 10 provided in a direction contacting the skin and a surface weaving layer 10 disposed on the top backing fabric layer 10, (20).

The weaving layer 10 and the surface woven layer 20 are formed by weaving a material having an inherent characteristic in a double weaving manner as will be described later. The double weaving structure is well known in which, for example, It is interwoven.

At this time, the surface woven layer 20 of the fabric knitted with the double structure is hydrophilic, while the back woven layer 10 that touches the skin has water repellency (hydrophobic) so that the hydrophilic portion sucks and evaporates the sweat, To provide quick drying and moisture absorption.

In general, the sweat-absorbing and quick-drying property of sweat or water vapor generated from the human body is absorbed and removed quickly by wearable clothes. By this, it means watering and drying amount in the entire fabric. As a structure for this, Have been proposed.

However, the sweat-absorbing and quick drying property provided by the present invention does not mean the absolute moisture content, but rather the moisture retained in the backing weft layer 10, which is in contact with the skin, is quickly transferred to the surface weave layer 20, .

Therefore, if the moisture retained in the backside layer can be rapidly diffused into the surface layer, assuming that the total amount of moisture contained in the entire fabric is the same, the skin can feel a feeling of dryness and freshness, and irrespective of the absolute evaporation or drying amount of moisture The sweat-fast drying property can realize physical properties.

To this end, the backing layer 10 is disposed on the back face contacting the skin of the fabric of the present invention, which is knitted in a double structure and is made of hydrophobic material fiber so as not to absorb gas phase or liquid phase perspiration.

At this time, the above-mentioned gas phase sweat means perspiration (persistent evaporation) constantly evaporating from the body, and sweat of the liquid phase means liquid phase sweat (detection extension) discharged according to exercise or the surrounding environment.

Of course, since the present invention provides a moisture-absorbing and quick-drying property to make the skin comfortable, the 'sweat' removed for the quick-drying moisture absorption may also include various 'moisture' touching the skin in addition to sweat discharged from the human body.

The surface woven layer 20 is knitted in a double structure with the above-mentioned backing weave layer 10 and is woven with hydrophilic material fibers to absorb perspiration in a gaseous or liquid state differently from the back woven layer 10.

In particular, the backing layer 10 of the present invention includes a water-repellent portion 11, which is a passage through which sweat migrates. On the other hand, the surface woven layer 20 includes an absorbent portion 21 for absorbing sweat introduced through the water-repellent portion 11, a diffusion portion 22 for dispersing sweat absorbed by the absorbent portion 21, And a evaporator 23 for evaporating the sweat diffused in the diffuser 22.

Therefore, since the back woven layer 10 exposed to the skin is made of a hydrophobic material, the sweat moves (penetrates) through the water-repellent portion 11, and the sweat moved at the same time passes through the surface woven layer 20 of hydrophilic material, And is spread in the entire surface woven layer 20 in the diffusion portion 22 after the absorption (left and right diffusion), and evaporated in the evaporation portion 23.

FIG. 3 conceptually illustrates the fabric of the present invention as described above. As shown in the figure, the water repellent portion 11 of the back woven layer 10 is woven with hydrophobic material fibers that do not absorb sweat (moisture) and is formed in the gap between the woven hydrophobic material fibers.

At this time, the surface woven layer 20 is woven with a hydrophilic material fiber capable of absorbing sweat, and the absorbent portion 21 is woven so as to be exposed between the water-repellent portions 11 of the back woven layer 10. The diffusion portion 22 is provided continuously to the absorption portion 21 and the evaporation portion 23 is provided on the outermost surface exposed to the atmosphere. Thus, the diffused sweat is evaporated into the outside atmosphere.

Strictly speaking, the absorbing portion 21, the diffusing portion 22, and the diverging portion are integrally provided in one surface woven layer 20 woven with a hydrophilic material fiber, so that the entire woven surface woven layer 20 provide both the characteristics of the absorber 21, the diffuser 22 and the diverging portion.

4A is a woven fabric showing a moisture-absorbing and quick-drying fabric of a double weave structure according to an embodiment of the present invention. FIG. 4B is an enlarged view of an actual fabric woven in a manner as shown in FIG. Respectively.

FIG. 4A illustrates a case where the backing layer 10 is applied to a fabric woven in a PK (PIQUE) manner. The PK fabric is a structure in which the surface touching the skin is oblong, and the state after the weaving is honeycombed, do.

In this case, the hydrophobic material fibers shown in black in FIG. 4A form the backing weave layer 10, and the hydrophobic material fibers are spaced apart at regular intervals to form the water repellent portion 11. The water-repellent portion 11 protrudes toward the human body and touches the skin.

On the other hand, the hydrophilic material fiber expressed in white forms the surface woven layer 20, and the hydrophilic material fiber is knitted into the double structure by interweaving with the hydrophobic material fiber, (22) and the evaporator (23) are formed.

More specifically, FIG. 4B shows the actual fabric to which the present invention is applied in a magnification of 2000, where white is hydrophobic material fiber (opposite color in FIG. 4A) and black is hydrophilic material fiber (opposite color in FIG. 4A) .

Fig. 4b differs from that of Fig. 4a in the color of the fibers. That is, the hydrophobic fibers and the hydrophilic fibers applied to the present invention are not particularly limited in their hue. The water repellent portion 11 is formed on the back woven layer 10, and the absorbent portion 21, the diffusion portion 22, and the evaporation portion 23 are formed.

5 is a photograph of a moisture-absorbing quick-drying fabric of a double weave structure according to another embodiment of the present invention. As shown in the drawing, the present invention is also applicable to a case where the back woven layer 10 of the fabric is woven in a corrugated manner.

In this case, the water-repellent portion 11 of the woven layer 10 may be formed as a line like a rib structure (e.g., a wrist serpentine). That is, FIG. 5 differs from FIGS. 4A and 4B in that the water repellent portion 11 of the backing layer 10 is a hole (for example, a mesh or a zigzag structure).

Accordingly, the present invention is not limited to the case in which the water repellent portion 11 is provided on the backing layer 10, and the absorbent portion 21, the diffusion portion 22 and the evaporation portion 23 are provided on the surface woven layer 20 , There is no particular restriction on the weaving method, the weave pattern or the texture.

The water repellent portion 11 of the back woven layer 10 forms a water repellent space for each gap between the hydrophobic material fibers and the water repellent space itself forms the capillary so as to be directed toward the surface woven layer 20 by the capillary phenomenon It is preferable that the size of the sweat is controlled so as to move.

For example, since the size of the sweat of the liquid phase is in the range of about 100 .mu.m to about 3000 .mu.m, the gap between the water repellent portion 11 of the back woven layer 10, that is, the woven hydrophobic material fibers may be 100 .mu.m to 3000 .mu.m or more so that capillary phenomenon can occur.

The hydrophobic material fiber that does not absorb sweat (moisture) to constitute the backing layer 10 is a polypropylene fiber. The hydrophilic material fiber is made of a hydrophilic material fiber so as to absorb sweat (moisture) to form the surface woven layer 20 Polyester fibers or nylon fibers.

In addition, the hydrophobic material fiber is preferably a circular cross section having a circular section so as not to stimulate the skin, and the hydrophilic material fiber is preferably a polygonal cross section having a larger surface area than the circular cross section yarn.

By using the backing layer 10, which is in contact with the skin, as a circular cross-section yarn, it is possible to contact the skin to give a soft feeling without stimulation. On the other hand, the surface woven layer 20, which has to absorb sweat, can greatly improve the absorption surface area and improve the evaporation characteristics by using a deformed cross-section yarn such as a four channel structure, a triangular structure and a lattice structure.

It is preferable that the hydrophobic material fibers constituting the back surface woven layer 10 have a low density and the hydrophilic material fibers constituting the surface woven layer 20 are three dots of high density having higher density than the hydrophobic material fibers.

The fineness means mono-denier of short fibers (monofilament), and the hydrophobic material fiber makes it possible to constitute micro-capillaries by using a taekwondo yarn. The hydrophilic material fiber makes it possible to improve the sweat absorbing performance remarkably by using the high-density three-ply yarn.

Further, it is preferable that the mixing ratio of the hydrophobic material fibers is 25% to 55% of the total fabric, and the mixing ratio of the hydrophilic material fibers is 75% to 45%. At this time, it is preferable that the surface area of the hydrophobic material fibers contacting the skin is 90% or more.

As shown in FIGS. 4A and 4B, hydrophobic material fibers constituting the woven layer 10 are adjusted to 25% to 55% to form fine capillary tubes between the fibers when the fabric is doubly woven.

At the same time, the hydrophilic material fibers constituting the surface woven layer 20 are adjusted to 75% to 45% to improve the absorption, diffusion and evaporation characteristics by providing a hydrophilic material fiber of sufficient density to absorb sweat and moisture.

In addition, the hydrophobic material fibers of the backing weft layer (10) contacting the skin when worn are made to have a surface area exceeding 90% of the skin so that the sweat is evaporated while minimizing the contact of the hydrophilic material fibers absorbing the sweat to the skin I will.

As described above, the present invention provides a water-repellent form having a woven fiber-like nature, rather than providing a water-repellent treatment with chemicals, while the water-repellent portion 11 provided on the fabric provides excellent moisture-absorbing and quick-drying property.

Therefore, the water-repellent portion 11 is fully preserved in spite of the external impact applied to the fabric, such as when the fabric is post-processed or the finished textile is worn or washed, so that the moisture- The life span becomes longer.

In addition, the moisture-absorbing and quick-drying fabric according to the present invention is formed on the back surface of the water-repellent portion 11 in contact with the wearer's skin, and the hydrophilic portion is formed on the outer surface of the wearer.

Accordingly, the sweat is quickly moved to the hydrophilic part of the fabric through the plurality of absorption holes provided in the water-repellent part 11, and then diffused and evaporated into the air, so that the skin surface is always kept dry without moisture and the wearing comfort is greatly improved I will.

In addition, the moisture-absorbing and quick-drying fabric according to the present invention is optimized in terms of the structural side surface and the surface area, thereby maximizing the moisture-absorbing quick-drying function.

In addition, the back surface, which is in contact with the skin according to the present invention, is harmless to the human body with an eco-friendly material, thereby providing a safe feeling to the user of the sensitive skin.

In addition, since the back surface contacting with the skin according to the present invention does not contain moisture, it does not cause propagation of germs and maintains a pleasant condition. Also, it provides antifouling property with high resistance to contamination and also reduces the damage degree of the fabric, Let it grow longer.

Furthermore, the moisture permeability according to the present invention proves that excellent moisture permeability of 10,000 g / m 2/24 h or more is obtained in the moisture permeability test according to calcium chloride which measures the amount of water vapor passing through a unit area for a unit time in prescribed temperature and humidity. Therefore, it plays a role of maintaining the internal temperature and is excellent in the property of keeping the body temperature of the user by shutting off the external temperature due to the thermal conductivity.

In addition, the weight of the present invention is lower than that of the same thickness due to the intrinsic characteristics of the fiber material, and the back surface is free of moisture, so that the surface woven layer except the woven layer (10) 20), it is lighter than other fabrics with high moisture-absorbing and quick-drying fiber mixing ratio even when sweat is absorbed.
