The present invention relates to a moisture control fiber structure 100 of a double-sided pile fabric composed of a support layer 110 and a pile 130 formed on the upper and lower surfaces of the support layer as shown in FIG. 1.

The support layer 110 and the pile 130 of the double-sided pile fabric are formed of multifilament yarn, and the pile includes a pile having a hydrophobic coating layer 150 formed thereon.

The multifilament yarn has a structural feature in which a plurality of filaments are aggregated to form a single thread, and has a moisture control ability to absorb moisture by expressing a capillary phenomenon of moisture or to quickly transfer the absorbed moisture to another site.

It will be more preferable that the multifilament yarns of the support layer 110 and the pile 130 are formed of microfibers formed of split yarns or island-in-the-sea yarns in order to increase moisture control.

When the multifilament yarn is formed of microfiber, moisture absorption and transmission through the capillary phenomenon are greatly improved.The microfiber preferably has a fineness of 0.5 denier or less as a mono fineness, and it is more preferable that the microfiber is less than 0.1 day. .

The pile length (L) of the double-sided pile fabric means the length from the support layer to the surface contacting the outside as shown in FIG. 1, and the pile length (L) can be adjusted according to the purpose of use of the moisture control fiber structure, For moisture absorption and storage, it is preferable to be at least 0.5 mm.

The thickness of the double-sided pile fabric related to the pile length (L) can be adjusted according to the purpose of use of the moisture control fiber structure, and it is desirable to be adjusted to 2 to 20 mm depending on the purpose of use of the moisture control fiber structure. will be.

When the thickness of the double-sided pile fabric is less than 2 mm, the moisture retention power may be lowered, and when the thickness exceeds 20 mm, the moisture control power may be lowered.

The pile 130 on which the hydrophobic coating layer 150 is formed is included in the piles on the upper and lower sides of the double-sided pile fabric to limit the movement of moisture, and the double-sided pile fabric can absorb moisture into the space between the piles. All of the fabric may be formed of the pile 130 on which the hydrophobic coating layer 150 is formed.

The double-sided pile fabric may be formed of a pile 130 on which a hydrophobic coating layer 150 is formed and a pile 130 on which a hydrophobic coating layer is not formed in order to further increase moisture absorption. For smooth moisture control, the pile of the double-sided pile fabric is It would be desirable to be formed of a pile on which the hydrophobic coating layer 150 is formed at least 70%.

That is, it will be preferable that the pile on which the hydrophobic coating layer 150 is formed is included in 70 to 100% of the piles on the upper and lower sides of the double-sided pile fabric.

In addition, it is preferable that the piles formed on the upper and lower surfaces of the support layer are 35 to 80 piles/cm2, respectively. If the pile density is less than 35 piles/cm2, the gap between the piles increases to absorb moisture or limit the movement of moisture. If the pile density exceeds 80 pieces/cm2, the manufacturing processability of the double-sided pile fabric decreases, and the moisture absorption capacity may decrease due to the close contact between the piles, so it is preferable that the pile density is 35~80 pieces/cm2. More preferably, it is 50 to 65 pieces/cm 2.

In addition, as shown in FIG. 1, when the length of the pile is L and the length of the hydrophobic coating layer formed on the pile is L, it is preferable to satisfy the following equation (1).

Equation (1) 0.05∠ℓ/L∠0.95

If the value of ℓ/L is less than 0.05, the length of the coating layer or too short may reduce the hand control power. If the value of ℓ/L is more than 0.95, the length of the hydrophobic coating layer is too long, so moisture absorption is reduced and moisture is stored. Moisture retention power may be reduced due to a reduction in a possible area, and when a hydrophobic coating layer is formed on the support layer, the moisture retention power may be reduced.

It is preferable that the coating layer of the pile on which the hydrophobic coating layer is formed has a thickness of 20 to 150 μm. If the thickness of the coating layer is less than 20 μm, the coating layer may be peeled off during washing or rubbing. As it is attached, the texture of the fabric may be deteriorated.

Most preferably, the thickness of the coating layer of the pile on which the hydrophobic coating layer is formed is 50 to 80 μm.

The hydrophobic coating layer 150 is formed by coating the hydrophobic coating agent, and the hydrophobic coating agent is formed of a water-repellent agent and a binder as it is preferable that the hydrophobic coating agent is transparent and does not impede the inherent color of the fabric.

The water repellent may be a fluorine-based water repellent, a silicone water repellent, a fluorine-silicone water repellent, an acrylic water repellent, a polyethylene water repellent, a polypropylene water repellent, a polyamide water repellent, a polyester water repellent, polymethyl, etc. It is most preferable to use a silicone-based water repellent that is easy to form, and it will be preferable to use a silicone-based water repellent prepared by a sol-gel method using tetraethyl-orthosilicate (TEOS).

The water repellent may be used together with a solvent and a thickener to increase processability.

As the binder used in the present invention, any binder used for textile products may be used, and as an example, all of an acrylic binder, a silicone binder, a polyurethane binder, and the like may be used. Among the above binders, it would be preferable to use a transparent acrylic binder that has little skin irritation and is easy to use.

The water repellent and the binder are mixed and used, and the mixing ratio of the water repellent and the binder may be adjusted according to the water repellent and the binder used, and generally, the water repellent and the binder may be mixed in a weight ratio of 9:1 to 3:7.

The hydrophobic coating agent may form a hydrophobic coating layer on the pile of the double-sided pile fabric by various methods such as a spray spray method, a roll printing method, and a laminating method.

The double-sided pile fabric of the present invention preferably has a pile density of 35 pieces/cm2 or more.If the pile density is less than 35 pieces/cm2, the hydrophobic coating agent penetrates to the support layer when forming the hydrophobic coating layer, thereby reducing the moisture control and moisture retention of the moisture control fiber structure. have.

When the double-sided pile fabric of the present invention is formed of a pile with a hydrophobic coating layer and a pile without a hydrophobic coating layer, it is preferable to form a gap composed of a pile without a coating layer of 0.5 to 5 mm in order to more quickly absorb moisture. something to do.

The gap 400 serves as a passage through which moisture moves to a region formed of a pile in which the coating layer is not formed. When the width or length of the gap is less than 0.5 mm, the moisture absorption effect is not significantly increased, and when the width or length of the gap is greater than 5 mm, moisture is exposed to the top or bottom surface, thereby reducing the dryness of the fiber structure.

When the gap is formed as described above, the file on which the hydrophobic coating layer is formed is in the form of a dot as in FIG. 3(a), in the form of stripes as in FIG. 3(b), or in FIG. 3(c) It will be possible to design in a variety of designed patterns, such as in the form of a grid pattern.

The moisture control fibrous structure according to the present invention formed as described above is formed of an absorbing portion 200 through which moisture is absorbed through a pile in which a hydrophobic coating layer 150 is formed on the upper and lower surfaces of the double-sided pile fabric, as shown in FIG. A moisture storage unit 300 in which moisture is stored is formed between the hydrophobic coating layer 150.

In the present invention, the moisture control fibrous structure may absorb moisture through the gap or between the piles 130 formed of the hydrophobic coating layer 150 in the absorption part 200 due to the hydrophobic coating layer 150 at the top and bottom surfaces. In addition, the absorbed moisture is not exposed to the outside due to the pile formed with the hydrophobic coating layer formed on the upper and lower surfaces and stays in the inner space of the double-sided pile fabric.

The moisture storage unit 300 of the moisture control fiber structure of the present invention is a double-sided pile fabric that absorbs moisture due to a capillary phenomenon due to a large number of voids and microfibers inside, and the absorbed moisture moves to an inner space without moisture. Even if this is absorbed, moisture is controlled to be exposed through the upper and lower surfaces.

In addition, the moisture control fiber structure of the present invention has a high moisture retention power by controlling the movement of moisture from the upper and lower surfaces to the hydrophobic coating layer 150 with many voids therein, and has a moisture retention power of at least 5 times its own weight.

The moisture control fiber structure according to the present invention formed as described above absorbs moisture quickly, but controls the exposure of moisture to the outside by forcing the absorbed moisture to stay in the inner space of the fiber structure.

The moisture control fiber structure of the present invention preferably has a basis weight of 150 to 800 g/m 2, and the basis weight of the fiber structure may be adjusted according to the product to be manufactured.

With the above characteristics, the moisture control fiber structure according to the present invention may be applied to various products such as cleaners, bowel pads, towels, and flat sheets.

Hereinafter, examples of a method for manufacturing a moisture control fiber structure according to the present invention are shown, but the present invention is not limited to the examples.

Examples 1 to 6

Using 150D/72F (18 divisions) N/P dividing yarn, a tricot double-sided pile fabric having a thickness of about 5 mm (pile length of about 2 to 2.5 mm) was prepared.

A hydrophobic coating agent was sprayed on the upper and lower surfaces of the double-sided pile fabric by spraying the hydrophobic coating agent and heat-treated at about 160 to 170° C. to form a hydrophobic coating layer to prepare the moisture control fiber structure of the present invention.

A value of ℓ/L of the length (L) of the pile of the double-sided pile fabric and the length (ℓ) at which the hydrophobic coating layer is formed was adjusted to about 0.3 to 0.4.

The thickness of the hydrophobic coating layer was adjusted by controlling the surface area of the fabric and the hydrophobic coating agent sprayed, and the actual thickness of the hydrophobic coating layer was measured through SEM and shown in Table 1.

The hydrophobic coating agent was prepared by mixing a silicone-based water repellent prepared by a sol-gel method and an acrylic binder in a weight ratio of 8:2 using tetraethylosilicate (TEOS).

The tri-coated double-sided pile fabric was prepared by varying pile density and basis weight according to Examples, and the pile density and basis weight according to the Examples are shown in Table 1.

Comparative Example 1

The same tricot double-sided pile fabric as in Example 1 was used.

Comparative Example 2

Although prepared in the same manner as in Example 1, a moisture-controlled fiber structure was prepared by spraying so that a hydrophobic coating layer was formed up to the support layer of the tricot double-sided pile fabric.

* Tactile evaluation: Tricot double-sided pile fabric formed of N/P split yarn of 150D/72F (18 divisions) without a hydrophobic coating layer was evaluated as a comparative example, and relative sensory evaluation by 5 experts compared to the comparative example was conducted (100 If there is no difference in touch from the comparative example with a perfect score, give a high score)

* Moisture retention: 4g of fabric was immersed in distilled water for 30 seconds, suspended in the air for 10 seconds to remove excess moisture, and then the weight of the fabric was measured and calculated by the following equation.

Moisture retention (%) = (Weight of fabric absorbed moisture)/(Weight of fabric before moisture absorption) X 100

As shown in Table 1, as the thickness of the hydrophobic coating layer decreases, the touch is similar to that of Comparative Example 1. The lower the thickness of the hydrophobic coating layer, the better the touch, and the larger the thickness, the lower the touch. In the case of 50 to 80 μm, the tactile feel does not significantly decrease.

Durability will improve as the thickness of the hydrophobic coating layer increases.

In addition, as shown in Table 1, the moisture control fiber structure having the hydrophobic coating layer of the present invention has a moisture retention capacity of about 800 to 1100%, and it can be seen that the moisture retention capacity is significantly improved compared to Comparative Example 1 in which the hydrophobic coating layer is not formed.

In addition, as in Comparative Example 2, when the value of ℓ/L in which the hydrophobic coating layer is formed up to the support layer is 1 or more, it can be seen that the flexibility of the fabric is lowered, the touch is rapidly deteriorated, and the moisture retention power is greatly lowered.

◎ Evaluation experiment

The moisture control force measurement of the moisture control fiber structure of the present invention prepared above was measured by the method of AATCC 195-2009 (water behavior measurement).

The experiment was an experiment in which distilled water was dropped on one side of the fabric to measure the moisture behavior in the fabric. The water behavior was measured by dropping distilled water on one side of the moisture control fiber structure of the present invention prepared in Example 4. For the comparative evaluation, the tricot double-sided pile fabric of Comparative Example 1 was used.

As shown in Table 2, in the comparative example not having the pile with the hydrophobic coating layer formed, the R value was 307.684%, indicating that the moisture was absorbed from one side to the other side, but the moisture control fiber structure of the present invention of Example 6 was R As the value is negative, it can be seen that the one side and the other side where moisture is absorbed are not transferred and are stored inside.

That is, it can be seen that moisture absorbed by the pile having a hydrophobic coating layer formed on the upper and lower surfaces of the double-sided pile fabric of the present invention is stored without being exposed to the upper and lower surfaces.
