Description

Manufacture method of packable wear-resistant moisture-resistant waterproof fabric and excellent moisture-proof waterproof fabric produced by the present invention {Preparing method of packable fabric having excellent dry property and durability and fabric

The present invention relates to a manufacturing method of a packable wear-resistant moisture-proof waterproof fabric excellent in dryness and a moisture-permeable waterproof foam produced by the present invention, and more particularly, coating the surface treatment agent resin composition of a specific composition on the fabric by direct coating or transfer coating method The present invention relates to a method for producing a packable wear-resistant moisture-permeable foam having excellent dryness and improved lightness and packability by maximizing abrasion resistance, dryness and comfort when contacting the skin, and thus eliminating lining. .

The waterproof coating fabric is widely used in various active sportswear and casual wear such as skiing, golf wear, hiking, mountain climbing, jogging clothes, etc. The outer textile fabric is mainly manufactured by the waterproof coating of non-thick synthetic fiber fabric. It is common. In addition, the water-repellent waterproof fabric is usually applied to water repellent in order to reject moisture from the outside is applied to the water repellent (executed before the moisture-repellent waterproof coating) or after water repellent (after the moisture-repellent waterproof coating) is applied.

In general, the moisture-permeable waterproof fabric has a two-layer structure consisting of a fiber layer and a coating layer, and a three-layer structure consisting of a fiber layer (outer fabric), a coating layer, and a fiber layer (lining). In the end, it will be a three-layer fabric. Therefore, due to the addition of the lining paper, the touch becomes dull, the volume and weight are increased, and the manufacturing cost has been disadvantageous.

In addition, there has been a problem that the volume and weight becomes very uncomfortable when folded and packed for portable for intermittent use for summer or temporary waterproof windproof.

Conventionally, products for which the gravure printing or the intaglio pattern surface treatment were designed on a two-layer coating fabric for packable purposes for the purpose as described above, but these have no unevenness or wear resistance, It is not scratch-resistant and lacks the peculiar smooth and dry feeling.

 In addition, even if given the unevenness, there is a weak wear resistance or scratch resistance due to insufficient washing durability and poor antibacterial deodorization performance of the coating surface, there is a disadvantage that can not prevent the occurrence of odor due to sweat during exercise.

For example, in Korean Patent Laid-Open Publication No. 2004-0004301, a method of foaming a surface treatment agent with a foaming agent is used to give an unevenness, but since a foam cell is formed on the surface, abrasion resistance is poor, leaving marks on scratches. I have a problem. In addition, stone powder, silicon earth, calcium carbonate, etc., which are used as an uneven subsidiary, have difficulty in providing slip property of the surface after processing, and have a disadvantage in that they are not robust to washing or dry cleaning.

In terms of the appearance of unevenness by the design of the plate making roller, when designing with a depth of about 7 to 12 microns by the film corrosion method as in the patent, there is an intrinsic solid content of the surface treatment agent formulation, and usually from gravure roll to fabric It is practically difficult for the transition rate of to exceed 70%, so the adhesion height from the surface of the actual coating fabric after the surface treatment is very low, about 30% or less of the depth on the plate making.

The present invention has been made to solve the problems of the prior art as described above, the object of the present invention is not only good wear feeling due to excellent dry feeling and wear resistance, but also light weight and small volume when folded, excellent packable properties when sewing lining paper It is to provide a method of manufacturing a moisture-proof waterproof cloth that is not required.

Another object of the present invention is to provide a packable moisture-proof waterproof fabric excellent in the dry feeling and wear resistance produced by the above method.

Another object of the present invention is to provide a coating surface treatment resin composition that is used in the manufacturing method and can impart excellent dry feeling and wear resistance to the product.

The manufacturing method of the packable wear-resistant moisture-proof waterproof fabric excellent in the dryness of the present invention comprises the first step of performing a water-repellent process on the fabric; A second step of performing a waterproof coating on the water repellent fabric; A third step of transferring and coating the surface treatment agent resin composition containing glass pearl on the fabric which has been supplied to the roll by the moisture-permeable waterproof coating; And a fourth step of drying the precoated fabric.

In the present invention, the transfer coating of the third step is to supply the surface treatment agent resin composition on the surface of the intaglio roll to block both sides to prevent the deviation of the resin composition, scraping the surface of the roll uniformly with a scraper outside the intaglio After removing the resin composition in the region of the coating is preferably performed to the transfer coating to a predetermined thickness on the surface of the waterproof fabric.

The inorganic antimicrobial agent is preferably an inorganic ceramic material zeolite.

In addition, in the surface treating agent composition, the glass pearl may have a particle size distribution of 5 to 100 microns and a spherical shape, and may be any one or a mixture of two or more of barium oxide, titanium oxide, and silica (SiO ₂ ). In addition, the blocking agent is preferably a fine silica powder.

In the surface treatment agent composition, the polyurethane resin is preferably a 1-component polyurethane resin.

In the surface treating agent composition, the mixed organic solvent is one or two or more mixtures selected from the group consisting of toluene, methyl ethyl ketone, dimethylformamide, isopropyl alcohol, xylene, perchloroethylene, acetone, and ethyl acetate. It is preferable.

It is preferable that the viscosity of the said surface treating agent resin composition is 2000 cps or more.

In the present invention, the heat treatment chamber employed in the drying step of the fourth step may be an indirect hot air type or a direct radiation heat method.

In the present invention, the solid content in the surface treating agent resin composition is preferably 30% or more.

According to another aspect of the present invention, the present invention is based on a weight ratio of 100 parts by weight of the liquid polyurethane resin, 10 to 100 parts by weight of mixed organic solvent, 10 to 100 parts by weight of glass pearl, 0 to 2 parts by weight of pigment pigment And it provides a fiber fabric surface treatment agent consisting of a mixture of 0.5 to 5 parts by weight of the antiblocking agent.

The present invention also provides a packable wear-resistant moisture-resistant waterproof fabric and clothes having the moisture-permeable waterproof foam excellent in dryness, characterized in that produced by the manufacturing method.

The present invention will be described in more detail below.

The manufacturing method of the packable wear-resistant moisture-proof waterproof fabric excellent in the dryness of the present invention comprises the first step of performing a water-repellent process on the fabric; A second step of performing a waterproof coating on the water repellent fabric; A third step of transferring and coating the surface treatment agent resin composition containing glass pearl on the fabric which has been supplied to the roll by the moisture-permeable waterproof coating; And a fourth step of drying the transfer coated fabric.

The moisture-permeable waterproof cloth is dyed and water-repellent processed after weaving the fabric, coated with a direct or transfer coating method with a synthetic resin coating solution, and then supplied in a rolled state, or after water dyeing after fabric weaving, the water-repellent processing is omitted, and the synthetic resin coating solution After the coating treatment to the water-repellent treatment (post-water repellent) can also be supplied to the transfer coating process of the third step in a rolled state.

Water-repellent coating and water-repellent coating of the first and second steps can be changed back and forth. If water-repellent processing before coating with synthetic resin coating solution from waterproofing fabric It is called hand processing.

After the transfer coating by the intaglio roll surface treatment method of the third step, a drying process of the surface treatment agent resin composition is included, which is performed in a chamber to which hot air is supplied.

On the other hand, when describing the surface treatment method of the intaglio roll in detail, the surface treatment agent resin composition is supplied on the surface of the intaglio roll to prevent both sides from being separated from the edge of the resin composition, and scraping the roll surface uniformly with a scraper, that is, After the removal of the resin composition in the portion other than the intaglio by the rotation of the roll to the fixed scraper to transfer coating to a predetermined thickness on the coating surface of the waterproof fabric.

The coating method is to take into account the viscosity of the surface treatment resin composition, of course, this coating method is to fill the resin composition in the pharmaceutical pan as in the prior art, when the roll is rotated and buried the resin composition scraped with a dog knife to adjust the pickup amount of the equator It will be understood by those skilled in the art that a conventional method may be employed.

That is, the surface treating agent resin composition may be transferred to a gravure roll for processing, but the high viscosity, that is, a solid drug may have a high viscosity due to its difficulty in working characteristics. 2,000 to 50,000 cps) resin composition can be uniformly and effectively transfer-fixed.

The transfer fixation principle of the surface treatment agent transfers the adherend between the intaglio roll and the cushion roll while passing the adherend, and transfers the surface treatment resin composition on the intaglio roll to the adherend. In the case where both the upper and upper ends are possible, it is more preferable to position the cushion roll at the lower end in view of the stability of the transfer.

The reason for the transfer coating method is to impart the unevenness to the coating surface of the waterproof fabric. To this end, the solid content of the surface treatment resin composition is required to be as high as possible, and the viscosity of the surface treatment resin composition is naturally increased due to the increase in the solid content. The higher will be readily understood by those skilled in the art.

As such, when the high viscosity is achieved, the amount of evaporation during the dry heat treatment process can be minimized, and further, the resin composition transferred from the intaglio roll can be transferred and fixed to a predetermined thickness.

In the present invention, when the intaglio roll coating, the depth of the intaglio roll is preferably 100 to 300 microns. If the depth of the intaglio roll is shallower than 100, the unevenness is insufficient, and when deeply plated more than 300 microns, uniform transfer of the resin composition may be difficult or the transfer pattern may be distorted. That is, when the depth is too deep compared to the size of the pattern, there is a fear that the transfer rate is poor.

The surface treatment agent resin composition used in the intaglio roll surface treatment step of the third step comprises a pigment pigment, a polyurethane resin, an inorganic antibacterial agent, an antiblocking agent, a glass pearl, and a mixed organic solvent.

Preferably, the surface treating agent resin composition is contained in a weight ratio of 100 parts by weight of the liquid polyurethane resin, 10 to 100 parts by weight of mixed organic solvent, 10 to 100 parts by weight of glass pearl, 0 to 2 parts by weight of pigment pigment, and blocking. It is preferably a mixture of 0.5 to 5 parts by weight of the inhibitor.

It is preferable that the surface treating agent composition further include an inorganic antibacterial agent or a bioceramic deodorant to 10 parts by weight or less.

The inorganic antimicrobial agent is a zeolite-based inorganic antimicrobial agent, which is an inorganic ceramic material and contains a silver (Ag) and zinc (Zn) in an ionic form. Excellent and desirable.

The surface treating agent composition may also be added with a substance for known anion release.

The glass pearl used as a preparation for complex functionalities such as dryness, abrasion resistance, unevenness and slipperiness is preferably a spherical form having a diameter of 5 to 100 microns, more preferably 8 to 40 microns, and as a composition example, BaO 45%, 40% TiO ₂ , and 15% SiO ₂ .

If the diameter of the glass pearl is less than 5 microns, the effect of complex functionalities is insufficient, and if the diameter of the glass pearl exceeds 100 microns, the surface touch is rough, and the wearability is poor. If the viscosity of the surface treatment resin composition is 2,000 cps or less, precipitation of spherical glass pearl is caused In this case, when spherical glass pearls are precipitated, the physical properties of the complex functionalities due to the treatment of the surface treating agent resin composition may be uneven, so that the viscosity of the resin composition is preferably 2000 cps or more.

In addition, it is preferable that the shape of the glass pearl is spherical. If the protruding portion of the surface becomes hemispherical or spherical, the slipperiness due to friction is excellent, and when the skin is in contact with the skin, it is not sticky and feels dry and comfortable. It can be given.

A commercially available fine silica-based powder may be employed as the antiblocking agent employed for the synergistic effect of drying.

In the surface treatment agent composition, the polyurethane resin is preferably a 1-component type polyurethane resin.

In addition, in the surface treating agent composition, mixed organic solvents used for dissolving and controlling the viscosity of the surface treating agent resin composition may include toluene, methyl ethyl ketone, dimethylformamide, isopropyl alcohol, xylene, perchloroethylene, acetone, It can be used alone or in combination of two or more solvents such as ethyl acetate.

The surface treating agent resin composition is preferably one-component polyurethane resin used as the main resin binder because it has good transferability in the intaglio roll and also eliminates surface stickiness after drying.

The pigment pigment is used from an aesthetic point of view since no lining paper is used.

Moreover, in this invention, it is preferable that the viscosity of the said surface treating agent resin composition is 2000 cps or more. If the viscosity is less than 2000 cps, it is not preferable because precipitation of glass pearl occurs and the dimensional stability of the pattern to be transferred during transfer coating may be destroyed.

Another effective way to impart unevenness to the coating surface is to design a high solids content of the final blended resin composition within a range that does not impair workability, specifically, if the solid content of more than 30% will be useful for expressing the effect.

In addition to adjusting the solid content of the formulation to impart a sense of unevenness, the effect of the increase in the depth of engraving at the time of roll engraving can be expected.

Usually, the rolled plate making method can be divided into a film corrosion plate and engraving plate, the film corrosion plate is subjected to corrosion by about 5 ~ 20 micron depth by applying a photosensitive solution to the copper plated cylinder, then developing the film. It is a way of expressing the intaglio pattern, and generally low depth pattern formation is possible.

On the other hand, engraving engraving method using the mill to express the intaglio pattern on the roll cylinder, and can usually express a depth of 100 ~ 500 microns, it will be easy to maximize the amount of coating transfer of the surface treatment agent resin composition. Of course, it will be readily understood by those skilled in the art that the size of the pattern, that is, the depth of the equator according to the number of necks, must be adjusted.

When sewing the surface-treated coating fabric instead of the lining paper of the present invention, in particular, in the case of waterproof or breathable waterproof fabric, it is natural that the surface treatment should be treated with the same pattern as the fabric even in the asymmetrical tape.

In the present invention, the heat treatment chamber employed in the drying process of the fourth step may be an indirect hot air type or a direct radiation heat method.

After surface-treating the surface-treated resin composition blended by the above method by intaglio roll coating or conventional front coating method, it is necessary to pass the heat treatment chamber to evaporate the used solvent, harden the resin binder and fix it to the fabric. Do. The heat treatment chamber may be indirect hot air or direct radiant heat. However, the direct heat radiation method requires special attention from the viewpoint of fire, etc., and preferably an indirect hot air method is preferable.

On the other hand, the use of a material that reduces the surface tension, for example, water repellents, softeners, waxes, etc. in the treated fabric during the treatment of the resin composition of the surface treatment agent not only reduces the transfer rate of the resin composition but also causes an increase in unevenness. This is good to avoid.

According to another aspect of the present invention, the present invention is based on a weight ratio of 100 parts by weight of the liquid polyurethane resin, 10 to 100 parts by weight of mixed organic solvent, 10 to 100 parts by weight of glass pearl, 0 to 2 parts by weight of pigment pigment And it provides a fiber fabric surface treatment agent consisting of a mixture of 0.5 to 5 parts by weight of the antiblocking agent.

The present invention also provides a packable wear-resistant moisture-permeable waterproof cloth excellent in the dry feeling, characterized in that produced by the manufacturing method.
