Abstract

PURPOSE:To obtain high-quality moisture-permeable fabric by casting a polyester resin incorporated with fine particles of a water-soluble compound or these particles plus fine particles of a water-insoluble protein on fabric followed by curing under an electric field and then washing out the water-soluble compound to effect formation of a porous film. CONSTITUTION:Fabric comprised of e.g. synthetic fibers is coated with a polyester resin solution prepared by incorporation a polyester resin with fine particles of a water-soluble compound (e.g. sodium chloride, sodium sulfate, or organic carboxylic acid, organic sulfonic acid) or these particles plus fine particles of a water-insoluble protein (e.g. cross-linked gelatin), followed by curing through application of a voltage on the surface and back surface of the fabric to effect formation of a resin film. Thence, the fine particles of the water-soluble compound in the film are washed out, thus forming a porous resin penetrated onto the surface and back surface. The resulting objective fabric having this porous film is high in moisture permeability, also excellent in the prevention of moisture condensation and touch feeling.

Means for Solving the Problems As a result of intensive studies to achieve the above object, the inventors of the present invention knead fine particles of a water-soluble compound in a solution of an organic solvent of a polyester resin, and use this as a cloth. After coating, when the resin film is cured while applying a voltage in the front and back directions, the obtained resin film is oriented with the fine particles connected in the front and back direction, and when washed with water thereafter, the fine particles are removed. It was found that the existing portions became voids, whereby a large number of micropores penetrating the front and back sides were formed, and the moisture permeability of the fabric was remarkably increased.

Further, according to the subsequent studies by the present inventors,
The resin film in the state where the fine particles of the water-soluble compound are connected in the front-back direction, that is, the latent porous resin film, instead of directly coating the kneaded product on the cloth, such as a glass plate or release paper. By casting the above to a desired thickness and curing it in an electric field in the same manner as above, it is possible to obtain a single resin film which is separate from the cloth, and after this film is attached to the cloth. Even if the fine particles were washed out with water to form a porous film, or the fine particles were washed out in the state of the film alone to form a porous film and then adhered to a cloth, the moisture permeability was remarkably increased. It has been found that a fabric is obtained as above.

Furthermore, the present inventors knead the water-insoluble protein fine particles together with the above fine particles in the polyester resin solution in which the fine particles of the water-soluble compound are kneaded in forming the latent porous resin film. In other words, by curing in an electric field after coating or casting, the protein particles are also oriented in a state of being connected in the front and back direction, and the protein particles are washed out with water like particles of a water-soluble compound. Without using a porous film, it is oriented in the above state even after it is made into a porous film, and since water vapor permeates through the protein particles connected in the front and back direction, the moisture permeability is further improved, and water absorption and condensation prevention Further, they have found that good results can be obtained also in improving the tactile sensation, which has been considered as a difficulty of the polyester resin moisture-permeable film.

Constitution and operation of the invention In the method for producing a moisture-permeable cloth of the present invention, the most significant feature is that the cloth is directly coated on the cloth or is cast on a glass plate or release paper to obtain a desired thickness. The point is to cure the resin solution containing the fine particles of the water-soluble compound or the fine particles of the water-insoluble protein cast in the above under an electric field, which is due to the fact that polar substances are oriented in the electric field direction under the electric field. It is based.

The present inventors chose fine particles of a water-soluble substance or fine particles of this and water-insoluble protein fine particles as the polar fine particles, and selected polyester resin as the medium, and the fine particles are oriented in the electric field direction under an electric field. In particular, if an electric field is applied in the front and back directions of the fabric or the casting layer, it is considered that the fine particles are oriented in the front and back directions. Based on this, after the resin is cured, the oriented fine particles of the water-soluble substance are washed out with water. Then, the place where the above-mentioned fine particles were present becomes a void, and a hole penetrating the front and back of the same diameter as the diameter of the fine particles is obtained, while the oriented water-insoluble protein fine particles are not washed out with water and are as they are. I thought that it would remain in the film in the state of, and this might give good results to moisture permeability and touch.
