Description

TECHNICAL FIELD The present invention relates to a coated fabric having a dry-touch texture.

(Prior Art) Conventionally, a coating process on cloth has been widely carried out in order to impart functions such as waterproofness, water repellency, and windproofness, and to impart surface changes such as color, gloss, and tactile sensation. In recent years, synthetic polymers such as polyacrylic acid ester, polyurethane and silicone resin have been used as the coating resin. Among the coated fabrics, those used for clothing tend to prefer a soft texture, and a soft synthetic polymer having a low glass transition temperature is often used. However, many soft synthetic polymers having a low glass transition temperature are remarkably sticky, and therefore, the surface of the coated cloth has a drawback that it becomes sticky and wet-touch.

Therefore, various methods have hitherto been tried in order to obtain a dry-touch coated cloth. One is surface treatment on the coating surface. This forms a thin film of a smoothing agent such as a silicon compound or a fluorine compound or a resin having a high glass transition temperature and a low stickiness on the surface of the coating film. The other method is a method of adding fillers to the coating resin liquid, and silica, titanium oxide, pulp powder or the like is used as the fillers. (For example, Japanese Unexamined Patent Publication No. 61-19877) (Problems to be solved by the invention) However, in many cases, a smoothing agent cannot sufficiently prevent stickiness, and a silicon compound causes unique sliminess. On the other hand, with a resin having a high glass transition temperature, the prevention of stickiness is sufficient, but the texture is apt to be hardened.
There are large changes in gloss and color.

In addition, in the method of adding fillers, a large amount of fillers must be added in order to sufficiently prevent stickiness, and the texture is likely to be hardened accordingly.

Therefore, conventionally, it has been impossible to obtain a dry-touch coated cloth which prevents stickiness of the coated surface without impairing the texture, the color of the coated surface, the gloss, and the like.

The present invention solves the above drawbacks by preventing the coating surface from changing in color and luster, and preventing the stickiness of the coating surface from being dry-touched without hardening the texture, especially making it paper-like. An object of the present invention is to provide a coated fabric.

(Means for Solving Problems) The present invention provides a coated fabric having a synthetic polymer film on at least one surface of a fiber structure, wherein the synthetic polymer film layer is partially exposed from the film surface. The dry-touch coated cloth is characterized in that metal soap particles having a melting point of 120 ° C. or higher are scattered.

The fiber structure referred to in the present invention includes woven fabrics, knitted fabrics, non-woven fabrics, and the like, and the constituent fibers thereof include natural fibers such as cotton, hemp, wool and silk, synthetic fibers such as nylon, polyester and acrylic, and those. May be mixed, but 20-60
A woven fabric containing 20% by weight or more of cotton yarn of a count is preferable for keeping the texture.

Examples of the synthetic polymer referred to in the present invention include polyacrylic acid ester resin, polyurethane resin, silicone resin, vinyl chloride resin and the like, and silicone resin is particularly preferable in terms of texture.

Further, the metal soap of the present invention refers to a metal salt other than an alkali salt such as fatty acid, resin acid, naphthenic acid, and examples of the fatty acid include oleic acid and stearic acid.
Metals other than alkali metals, such as calcium, zinc, aluminum, and the like, which are insoluble or sparingly soluble in the solvent of the resin liquid and have a melting point of 120 ° C. or higher, particularly calcium stearate, zinc stearate are melting points. It is preferred because it has high toxicity and is nontoxic.

The metal soap is in the form of particles obtained by a precipitation method or the like, and the shape thereof is not particularly limited, but fine particles having a particle size of 50 μm or less are preferable, and if the particle size exceeds 50 μm, spots and streaks are generated during coating processing. May occur.

The coated fabric of the present invention has a synthetic polymer film in which the metal soap particles are dispersed in the layer, and the metal soap weight is 5 to 50% by weight, more preferably 15 to 50% by weight based on the weight of the synthetic polymer film. It should be 35% by weight. However, it is necessary that a part of the metal soap particles is exposed from the surface of the synthetic polymer film, and the exposed portion is preferably about 5 to 30 μm.

Further, in order to prevent the hardening of the texture, the thickness of the coating film is preferably 20 μm or less, and the coating method may be either dry coating or wet coating. A floating knife coater, a knife over roll coater, A coating method such as a reverse roll coater, a roll doctor coater, a gravure roll coater, or a kiss roll coater can be used.

The exposed portion of the metal soap particles thus formed imparts lubricity to the surface of the coating film, and the lubricity suppresses slimy feeling and has a function of producing a dry tactile sensation.

In the present invention, it goes without saying that various treatments such as water repellency and softness may be applied in addition to the coating process. However, the water-repellent treatment can be performed either before or after coating, but if it is performed before coating, it is necessary to pay sufficient attention to the adhesive strength.

(Example) Example 1 A cotton yarn of 40 count twin yarn was used as a warp and a weft, and a warp density of 90
A plain woven fabric having a / inch and a weft density of 75 yarns / inch was dyed to obtain a cloth. Then, a resin solution prepared by mixing 10 parts of calcium stearate powder (particle size: about 10 μm) with 100 parts of a polyacrylic acid ester resin emulsion aqueous solution (solid content: 30%) was used on one side of the cloth using a floating knife coater. And then immediately dried at a temperature of 120 ° C.
Next, the cloth was subjected to padding treatment with a 5% by weight aqueous solution of a fluorine-based water repellent, followed by drying (120 ° C.) and heat treatment (150 ° C.).

When the surface of the coated cloth was observed under a microscope of 300 times, the exposed portion of the metal soap particles having a size of 5 to 10 μm was present.
The coating amount was 12 g / m ² (solid content), the surface had a dry touch without stickiness, and the texture was good. or,
After 3 times of washing (JIS L-217 103 method) and 3 times of dry cleaning (JIS L-217 401 method), neither damage to the coating film nor change in touch was observed.

Comparative Example 1 The coated fabric obtained by removing calcium stearate from the resin liquid of Example 1 had a content of about 10 as shown in Table 1.
The coating amount was g / m ² (solid content), and the coating surface was extremely sticky and had a wet touch.

Example 2 A 70d / 18f nylon filament bifilament was used as a warp and a weft, and a plain fabric having a warp density of 112 threads / inch and a weft density of 90 threads / inch was subjected to dyeing and water repellent treatment with a fluorine-based water repellent. A cloth was obtained. Subsequently, a resin solution prepared by mixing 5 parts of zinc stearate powder (particle size: about 10 μm) with 100 parts of acrylic ester resin perchlorethylene solution (solid content 12%) was applied to one side of the cloth by a floating knife. It was applied using a coater and immediately dried (120 ° C) and heat-treated (150 ° C).

When the surface of the coated cloth was observed under a microscope of 300 times, the exposed portion of the metal soap particles having a size of 5 to 10 μm was present.
The coating amount was 7 g / m ² (solid content), the surface had a dry touch without stickiness, and the texture was good. Further, after 10 times of washing, neither damage to the coating film nor change in touch was observed.

Comparative Example 2 The coated fabric obtained by removing zinc stearate from the resin liquid of Example 2 was about 5 g / m ^{2 as} shown in Table 1.
