【表】DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention provides a method of using a
The present invention relates to a breathable, waterproof, stretchable fabric with a soft texture and stretch properties. Conventional technology and problems to be solved by the invention In the past, many waterproof and breathable fabrics have been proposed in which urethane polymers, polyacrylic acid ester resins, tetrafluoroethylene resins, etc. are coated or laminated on fiber base fabrics. However, recently there has been an increasing need for fabrics that not only have the various functions that these fabrics have, but also maintain the elasticity of the fibers themselves, as well as having waterproofness and moisture permeability.
As a proposal to meet these needs, we applied a urethane polymer to water-repellent taffeta using a knife-over roll coater, then attached a stretchable base fabric under no load and no tension, and then bathed it in water. A method in which a microporous film is obtained by dipping the taffeta into a product, and then the taffeta is peeled off to obtain a product, or a method in which a polytetrafluoroethylene resin is coated in dots on a stretchable base fabric using a gravure roll, There are methods such as laminating a polyamino acid-modified urethane with a stretchable base fabric. Although waterproof properties can be obtained with any of these methods, there is a drawback that sufficient moisture permeability is difficult to obtain. The present invention aims to eliminate such drawbacks in the prior art and provide a stretchable fabric that is excellent in both waterproofness and moisture permeability. Means for Solving the Problems The present invention provides a moisture-permeable waterproof elastic fabric. The fabric of the present invention is a moisture-permeable, waterproof, stretchable fabric in which a microporous membrane made of a polymeric material is adhered in dots on at least one side of a stretchable fiber base fabric with an adhesive made of polyurethane. The adhesive exhibits a moisture permeability of 4000 g/m 2 /24 hours or more when formed into a film with a thickness of 1 μm. That is, the present invention is characterized in that, in the construction of a stretchable fabric in which a microporous membrane made of a polymeric material is bonded onto a stretchable base fabric, the membrane is bonded in dots using a polyurethane adhesive. Its moisture permeability is 4000g/m 2 /24 hours or more, and its water pressure resistance is
It is preferable that the peel strength is 900 mmH 2 O/cm 2 and the peel strength is 200 g/cm or more. In the production of the moisture-permeable waterproof elastic fabric of the present invention, examples of polymeric materials that provide a microporous membrane having moisture permeability and waterproof properties include polyester-based urethane polymers, polyale-based polymers, and polyacrylic acid. There are polymers, amino acid-modified urethane polymers, etc., but any material can be used as long as it has the function of forming a microporous film. However, in the present invention, it is necessary to form a film having extremely small pores in order to provide moisture permeability and waterproofness, and at the same time to form uniform cells inside the film. Therefore, in order to form a microporous membrane, it is common to form a film using a wet coagulation method using a polyurethane polymer. It is necessary to prepare the For example, a liquid preparation is prepared by blending 0.5 to 2 parts of a fluorine-based water repellent and 5 to 20 parts of aluminum hydroxide into a solution of a polar organic solvent such as dimethylformamide containing 100 parts by weight of a polyurethane polymer. gives good results. Addition of a water repellent is preferable because it has the effect of imparting durable water repellency to the resulting fabric. Water repellent content
When the amount is less than 0.5 parts by weight, sufficient water repellency cannot be obtained, while when it is more than 2 parts by weight, wet film formability and non-uniformity of the microporous film tend to occur during wet coagulation. Addition of aluminum hydroxide has the effect of improving the blocking properties of the wet film and also has the effect of forming uniform cells inside the film. Furthermore, being inexpensive leads to a reduction in resin cost. If the amount of aluminum hydroxide added is less than 5 parts by weight, adequate blocking properties cannot be obtained, and if it is more than 20 parts by weight, the moisture permeability of the microporous film will be reduced. The above-mentioned liquid mixture is coated uniformly to a desired thickness using a knife-over-roll coater or other conventional coating machine. Next, an adhesive made of polyurethane is applied dotted onto this microporous membrane using an appropriate means such as a gravure coating machine or a rotary screen printing machine, and then the elastic base fabric is placed in a no-load, no-tension state. Paste it with In this case, this polyurethane adhesive
When formed into a film with a thickness of 4000g/m 2 /
The material must have a moisture permeability of 24 hours or more. Examples of such polyurethane adhesives useful in the present invention include urethane resins obtained from polyamino acid-modified urethane resins, hydrophilic polyethylene glycol, etc., and porous resins obtained by chemical foaming, mechanical foaming, etc. be able to. Although the shape and form of the dots are not particularly limited, from the viewpoint of maintaining moisture permeability and improving peel strength, it is appropriate that the size of the dots is 0.01 to 10 mm 2 . If the size is less than 0.01 mm 2 , sufficient peel strength cannot be obtained, and if it is more than 10 mm 2 , this may result in a decrease in moisture permeability. Effects of the Invention The fabric of the present invention thus obtained is a fabric with excellent waterproofness, high moisture permeability, and high stretchability without any deterioration in feel. Examples Hereinafter, the present invention will be explained by giving specific examples. still,
In the following description, parts and percentages are by weight unless otherwise specified. Example 1 Nylon taffeta is treated with a silicone water repellent. Approximately 230 g/m 2 of a resin liquid having the following composition was coated on one side of the taffeta thus treated using a knife over roll coater method, and after coagulating in water, the solvent was removed and then dried to obtain a microporous material.

After printing with 40 mesh dots, the same stretchable knit base fabric as in Example 1 was laminated under no load and no tension, and after an aging process, the nylon taffeta was peeled off. Note that the moisture permeability of a 1 μm thick film obtained from this resin liquid was 900. Crisbon 5010 (semi-one-component urethane polymer manufactured by Dainippon Ink) 70 parts Crisbon 4010 (two-component urethane polymer manufactured by Dainippon Ink) 30 parts MEK 50 parts DMF 10 parts Crosslinking agent (isocyanate) 5 parts Immerse it in an aqueous solution of a fluorine-based water repellent (Asahi Guard AG710).
After padding, it was dried and cured. This was compared with the fabric of Example 1. Example 2 On the urethane surface of the two-layer stretchable, moisture-permeable fabric obtained in Example 1, the following resin solution was further printed in 20 mesh dots using a gravure coating machine, leaving no stretchable knit base fabric. Laminated under no load or tension,
A three-layer stretch fabric was obtained. After an etching process, water repellency was imparted using an aqueous solution of a fluorine-based water repellent (Asahi Guard AG710).
