Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a fabric having a partially water-repellent coating layer,

The present invention relates to a fabric having a partial water-repellent coating layer, and more particularly to a fabric having a partial water-repellent coating layer which effectively prevents clothing from wetting due to sweating on the skin and effectively adhering to the skin.

Generally, when wearing underwear, sports clothes, toys, etc., the sweat from the skin permeates the skin, which causes the inconvenient phenomenon that the entire clothes adhere to the skin.

Many technical developments have been made in this regard. Especially, in the case of sportswear or mountain climbing clothes, a lot of lightweight high-priced products that have waterproof function and water repellent function are mixed.

However, as can be seen from the prior art, there are many cases where the difference between waterproof and water repellent is not clearly recognized and is often misunderstood.

In other words, waterproof means water-proof, and water-repellent means water-repellent. Waterproofing is literally used as a concept to prevent water from penetrating through the cloth and penetrate into the inside of the cloth. As described in the prior art, most of them are mistaken as "breathing". In other words, waterproofing is to prevent water from penetrating, and water repellent is misunderstood much by discharging water inside.

However, the precise meaning of water repellency means that a thin film is coated on the fabric of the fabric so that it is repelled so that it does not penetrate the surface of the fabric when the water reaches.

So, although it seems closely related to the breathing, it is strictly different concept.

Therefore, it is better to wear sportswear, mountaineering clothes, and exercise or breathing when climbing up and down the mountain. In addition, in the case of clothes that are in direct contact with the skin, such as underwear or toys, It is necessary to apply the concept so that the sweat from the skin does not penetrate into the clothes.

However, as described above, in the prior art including the above-mentioned prior arts, the concept is limited to the concept of moisture permeability. In particular, in the case of a fabric in direct contact with the skin, .

Korean Patent Registration No. 10-1092611 (Dec. 25, 2011), "Partial water-repellent coated fabric and its manufacturing method & Korean Unexamined Patent Publication No. 10-2015-0034962 (Apr. 20, 2015), "Coating composition containing flame retardant styrene resin and a resin layer coated with the coating composition, multi-functional cover fabric with high durability water- Method of producing functional cover fabric "

SUMMARY OF THE INVENTION The present invention has been made in view of the above-described problems of the prior art, and it is an object of the present invention to provide a fabric with a partial water repellent coating layer which effectively prevents clothing from wetting due to sweating on the skin, Which has its main purpose.

The present invention relates to a fabric having a partial water repellent coating layer comprising a water repellent coating layer 14 which is partly coated and fixed on the surface of a velvet fabric 10 or a general fabric 10 ' ; The water-repellent coating solution for forming the water-repellent coating layer 14 comprises 40% by weight of polyurethane and 60% by weight of a solvent, the solvent being 20-25% by weight of N, N-Dimethyl Formamide, 1-3% by weight of benzoyl peroxide (BPO), 3-7% by weight of CADURA E-10, 1-5% by weight of 2-hydroxyethyl methacrylic acid (2-HEMA) 3-4 weight parts of squalane, 5-6 weight parts of indole-3-butyric acid (IBA), 5-6 weight parts of dichlorodimethylsilane, 2-4 weight of aminopropyltriethoxysilane A water repellent coating layer formed on the surface of the water repellent coating layer, 2-3 parts by weight of tragacanth and remaining methyl methacrylate (MMA).

At this time, in order to induce gelation on the surface of the water-repellent coating solution to increase surface strength, 5-8 parts by weight of sodium silicates are added to 100 parts by weight of the solvent, and the surface slip property of the water- It is also characterized in that 3-6 parts by weight of dimethylpolysiloxane is further added to 100 parts by weight of the solvent.

Further, in the water-repellent coating solution, 2-4 parts by weight of talc powder having 1-2 microparticles, 1-2 parts by weight of polysorbate 80 and 2-3 parts by weight of diisocyanate were added to 100 parts by weight of the solvent Can be added.

INDUSTRIAL APPLICABILITY According to the present invention, it is possible to obtain an effect of preventing the clothes from getting wet and sticking to the skin due to perspiration from the skin, mainly in the field of clothing.

1 is a schematic process drawing showing a production example of a fabric according to the present invention.
FIG. 2 is an exemplary sectional view showing an example in which a water repellent coating layer is partially formed on a velvet fabric according to a preferred embodiment of the present invention.
3 is an exemplary sectional view showing an example in which a water-repellent coating layer is partially formed on a general fabric according to a preferred embodiment of the present invention.
4 is an exemplary photograph of a velvet fabric used in the present invention.
5 is an exemplary photograph of a plain fabric used in the present invention.

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

Before describing the present invention, the following specific structural or functional descriptions are merely illustrative for the purpose of describing an embodiment according to the concept of the present invention, and embodiments according to the concept of the present invention may be embodied in various forms, And should not be construed as limited to the embodiments described herein.

In addition, since the embodiments according to the concept of the present invention can make various changes and have various forms, specific embodiments are illustrated in the drawings and described in detail herein. However, it should be understood that the embodiments according to the concept of the present invention are not intended to limit the present invention to specific modes of operation, but include all modifications, equivalents and alternatives falling within the spirit and scope of the present invention.

As shown in FIGS. 1 to 5, a fabric having a partial water repellent coating layer according to the present invention may include a water repellent coating layer 14 partially coated on one side of a fabric 10 or 10 ' 14 are dried through a dryer 40 and then the fabric 10 or 10 'is passed between the rubber roller 50 and the heat roller 60 so that the water repellent coating layer 14 is pressed against the fabric 10, Lt; / RTI >

At this time, the fabric 10, 10 'may be divided into a velvet fabric 10 having a nap 16 and a plain fabric 10' without a brushed 16 as shown in FIG.

In addition, the water-repellent coating layer 14 should be formed on the surface which is in direct contact with the skin when it is worn after being made into clothes.

The surface of the fabric 10 or 10 'itself is minimized to the contact area with the skin by partially forming the water repellent coating layer 14 at a predetermined interval, .

In addition, in the case of the velvet fabric 10 having the brim 16, it is particularly preferable to obtain the embossing effect by placing the brim 16 and the water-repellent coating layer 14 lower than the upper end of the brim 16 with a step difference Do.

The cloth 10 and 10 'are coated with the water-repellent coating solution 22 by a coating roll 30 rotated on a solution pan 20 in which the water-repellent coating solution 22 is stored, A coating is formed by a transfer method. For this, a groove 32 is formed on the outer circumferential surface of the coating roll 30.

In addition, the dryer 40 preferably maintains a drying temperature of about 140 ° C.

In order to realize such a fabric, in the present invention, a water-repellent coating solution for forming the water-repellent coating layer 14 is prepared as follows.

First, the water-repellent coating solution is composed of 40 wt% of polyurethane and 60 wt% of solvent, wherein the solvent is 20-25 wt% of N, N-Dimethyl Formamide, 3 to 7% by weight of 2-hydroxyethylmethacrylic acid (2-HEMA), 2 to 4% by weight of silicone, 3-4 parts by weight of squalane, 5-6 parts by weight of indole-3-butyric acid (IBA), 5-6 parts by weight of dichlorodimethylsilane, 2-4 parts by weight of aminopropyltriethoxysilane, -3 parts by weight and the balance methyl methacrylate (MMA).

At this time, the polyurethane is dissolved as a solid component by the solvent to form a liquid coating liquid.

Particularly, the polyurethane is composed of a combination of an alcohol group OH and isocyanate NCO, and there are polyester-series and polyether-series, but polyether-series is preferable in the present invention.

The polyether-based urethane is prepared by mixing propylene oxide with ethylene oxide and reacting OH groups at both ends with toluene diisocyanate to produce a high molecular weight polyurethane. The polyurethane thus produced has good ozone resistance and abrasion resistance.

N, N-Dimethyl Formamide (N, N-Dimethyl Formamide) in a solvent is a high polarity organic solvent and is a component mainly used in the production of urethane-based synthetic leather.

When the amount of the organic solvent is less than 20% by weight, the solubility of the solid polyurethane decreases. When the amount of the organic solvent exceeds 25% by weight, It is required to be limited to the above range because it decreases the adhesiveness.

In addition, benzoyl peroxide (BPO) in a solvent is a white solid and has a characteristic of easily breaking oxygen bonds due to heat or ultraviolet rays, and is usefully used as an initiator in radical polymerization.

That is, in the present invention, the coating layer function is lost due to the decrease in rigidity, and when it is added in an amount of less than 1% by weight, the hardness increases and the water-repellent coating layer 14 tends to be fragile It should be limited to the above range.

In addition, Cadura E-10 (CADURA E-10) in the solvent is a transparent water-white liquid as glycidyl neodecanoate, And particularly functions to maintain transparency by suppressing color development.

Therefore, if it is added in an amount of less than 3% by weight, it is difficult to maintain transparency. If it exceeds 7% by weight, adhesiveness is deteriorated.

In addition, 2-hydroxyethyl methacrylic acid (2-HEMA) in the solvent is sensitive to light and moisture, and the monomer is hydrophilic, and is mainly used as a raw material for paints and adhesives.

In the present invention, it is added to improve the durability of the water-repellent coating layer 14 in contributing to stabilization during the polymerization reaction.

Therefore, if it is added in an amount of less than 1% by weight, durability tends to be poor, and if it exceeds 5% by weight, hydrophilicity is deteriorated. Therefore, it should be limited to the above range.

Here, the water repellency is not a concept of moisture permeation, but rather induces water to flow from the surface of the fabric 10, 10 'to the surface of the fabric 10, 10' .

However, it is preferable that the velvet fabric 10 is added twice as much as the general fabric 10 'within the above range in order to maintain the fixing force because of the brushed 16.

And squalene is usually used as a health supplement, but in the present invention it is added for increasing the surface tension on the surface of the fabric 10, 10 '. That is, it is added to induce the surface to be as homogeneous as possible so that water droplets can be easily deposited.

In addition, IBA is indolebutyric acid, which is normally involved directly in the growth of plants, leading to hormone in the direction of carbohydrate flow, but in the present invention is added as a component to push moisture away from the surface to the edge.

In addition, the dichlorodimethylsilane has a very strong hydrophobic property due to the presence of two chlorine atoms, which are second electronegativity after fluorine (F), so that the water-repellent coating surface is not as close to water as possible, When added to induce the droplets to flow down into spheres by their surface tension, they are added in the same amount as IBA.

In addition, the aminopropyltriethoxysilane is added to increase the coupling property between the resin and the talc powder, which is an inorganic additive, and contributes to enhancement of bonding property, adhesiveness, and surface strength.

Further, the tragacantha is added as a kind of rubber component for viscosity control.

In addition, methyl methacrylate (MMA), which is the last component to be added to the solvent, is a colorless transparent liquid organic compound that causes polymerization well and is mainly used as raw material for producing organic glass, and is particularly important as an industrial raw material for unsaturated polyester resin.

In addition, the water-repellent coating layer 14 may be formed to be transparent or, in some cases, to have a color by adding a pigment.

In the present invention, it is added for improvement of impact resistance and improvement of durability in collision (not easily cracked or peeled), high strength and transparency, and excellent adhesive property.

In addition, in order to induce gelation on the surface of the water-repellent coating layer 14 to increase the surface strength, 5-8 parts by weight of sodium silicate is added to 100 parts by weight of the solvent, and the surface slip property of the water- , 3-6 parts by weight of dimethylpolysiloxane may be further added.

Further, 2-4 parts by weight of talc powder having 1-2 micrograms, 1-2 parts by weight of polysorbate 80 and 2-3 parts by weight of diisocyanate can be further added to 100 parts by weight of the solvent The talc powders were found to be useful minerals containing silicon oxide, magnesium, calcium and other materials. As a result of the analysis, talc itself was found to be a medicinal mineral having a far infrared emissivity of 93%.

Particularly, it is known that the water-repellent coating layer according to the present invention has an effect of promoting cell metabolism through expansion of capillaries by adsorption and convergence of magnesium, and further, It is added to maintain benefit to health promotion considering direct skin contact.

In addition, Polysorbate 80 (Polysorbate 80) is one of the non-ionic surfactants derived from sorbitol, added to prevent the spread of water, and diisocyanate can be added to accelerate curing.

Hereinafter, examples will be described.

[Example 1]

First, the following experiment was conducted to confirm the peeling possibility and cracking characteristics of the water-repellent coating layer according to the present invention. And, the object was performed only for general fabric.

The water repellent coating solution was composed of 40 wt% of polyurethane and 60 wt% of solvent. The solvent contained 22 wt% of N, N-Dimethyl Formamide, 2 wt% of Benzoyl Peroxide (BPO) 3 parts by weight of a polyvinyl butyral resin, 3% by weight of CADURA E-10, 2% by weight of 2-hydroxyethyl methacrylic acid (2-HEMA), 2% by weight of silicone, 3 parts by weight of squalane, -Butyric acid, 5 parts by weight of dichlorodimethylsilane, 2 parts by weight of aminopropyltriethoxysilane, 2 parts by weight of tragacanth and remaining methyl methacrylate (MMA).

In the experiment, a plain fabric with a water-repellent coating layer was put in a washing machine, followed by standard washing for 30 minutes using a neutral detergent, followed by rest for 10 minutes, followed by standard washing for 30 minutes, and then washing was taken out to check whether the water- (First wash).

After the drying, the fabric was allowed to stand at room temperature for 1 hour, then again for 30 minutes, then for 10 minutes, then again for 30 minutes, After the laundry was removed, it was checked whether the water-repellent coating layer was peeled off or cracked (second washing).

Lastly, the second fabric was allowed to stand at room temperature for 3 days, then washed for 60 minutes under the same conditions for 10 minutes, followed by standard washing again for 30 minutes, and then the laundry was taken out and checked for separation and cracking (Third wash).

No washing, peeling, or cracking occurred over the first, second, and third grades.

Then, in order to confirm whether or not water repellency was confirmed, water was sprayed on the inner surface of a general fabric having a water-repellent coating layer, that is,

At the start of the experiment, the water sprayed on the water - repellent coating layer was collected and flowed immediately. As a result, it was confirmed that the water repellent function was excellent.

[Example 2]

In the same manner as in Example 1, 5 parts by weight of sodium silicate and 3 parts by weight of dimethylpolysiloxane were added to 100 parts by weight of the solvent in the composition of the water repellent coating solution.

As a result of the experiment, it was confirmed that the water-repellent effect was better than that of Example 1 when observed visually.

[Example 3]

2 parts by weight of talc powder having a micro-particle size of 1-2, 2 parts by weight of Polysorbate 80, 2 parts by weight of diisocyanate Was added.

As a result of the experiment, it was confirmed that the same water repellency effect as in Example 1 was visually observed.
