Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for producing a dry-type moisture-permeable coated fabric, and more particularly, it has waterproof and moisture-permeable properties, has a soft texture, has a large tear strength, and is excellent in processing stability at low cost. The present invention relates to a method for producing a dry-type moisture-permeable coated fabric that can be produced in.

[0002]

2. Description of the Related Art A large number of waterproof and moisture-permeable coated cloths and manufacturing methods thereof have been disclosed. Typical examples thereof include a porous Teflon (registered trademark) film, a cloth laminated with a fiber base material using an adhesive agent on porous polyethylene, and a microporous film made of a polyurethane resin formed by a wet coagulation method and coated. Cloth (Japanese Patent Publication No. 60-47955, JP-A-8-3876)
Or a polyurethane in which a solvent-insoluble amino resin or silicon dioxide is mixed, an acrylic copolymer, or a silicone resin is formed on the fiber base material by dry coating (Japanese Patent Publication No. 62-53632,
JP-A-8-209541) and the like.

[0003]

However, the above-mentioned conventional coated fabrics have the following practical problems. That is, since the laminated cloth is laminated with the fiber base material using the adhesive, the obtained cloth has a very hard texture and the cost required for the processing is high.

Further, in the case of the cloth coated with the polyurethane resin microporous film by the wet coagulation method, the water-miscible organic solvent is mixed in the coagulation tank in the processing step, so that the labor and cost for distilling and recovering this solvent are high. However, there is a problem that the temperature control condition of the coagulation tank is narrow, or the processing speed is slow.

Further, regarding a dry coating moisture-permeable cloth made of a polyurethane, an acrylic copolymer, or a silicone resin mixed with a solvent-insoluble amino resin or silicon dioxide, if a general polyurethane resin for fiber processing is used, the viscosity of the resin is increased. Has a Newtonian viscosity. Therefore, when a base cloth having a low fiber density is used when a resin solution is applied to a fiber base material to obtain a coated fabric, a so-called back leakage phenomenon occurs in which the resin solution passes through the base cloth. In addition, when a base fabric having a feeling of unevenness is used, the coating amount is greatly different between the convex portion and the concave portion, which causes variations in various physical properties. Furthermore, even if the back leakage phenomenon at the time of processing is eliminated by selecting the base fabric, the coating compound liquid wraps around the back side of the coater at the time of coating with a floating knife, etc., and it looks like foreign matter on the processed fabric as a product. A so-called blade leakage phenomenon occurs, which occurs as uneven spots or stripes.

When the above polyurethane resin having Newtonian viscosity is used, an amino resin mixed with the polyurethane resin,
By selecting silicon dioxide, it is possible to change the viscosity of the coating resin solution to a non-Newtonian viscosity having a somewhat thixotropic property, but the amount of the amino resin, silicon dioxide, etc. mixed increases, and There is a problem of poor washing durability.

In the above, when the acrylic copolymer is used as the film forming component, the viscosity of the resin solution also becomes a non-Newtonian viscosity, and a fabric having a soft texture can be obtained. There is a problem that the seam tape used for the purpose of closing the hole of the needle formed at the time of sewing the sewing machine and maintaining the water resistance does not adhere to the coating cloth containing the acrylic copolymer as the film forming component when processing into .

The present invention solves the above-mentioned problems of the coated cloth by the conventional dry method, and achieves good water pressure resistance,
It has moisture permeability and soft texture, back leakage phenomenon during processing,
It is an object of the present invention to provide a dry, moisture-permeable coated cloth that is inexpensive, high-speed, and can be mass-produced without using a blade leakage phenomenon, by using materials and means different from conventional ones.

[0009]

A method for producing a dry and moisture-permeable coated cloth according to claim 1 is a polyfunctional monomer having two hydroxyl groups and / or amino groups in the molecule and a molecule having two or more hydroxyl groups and / or amino groups in total. A method in which an organic solvent solution of a hydrophilic polyurethane resin composed of a polyfunctional monomer having three or more hydroxyl groups and / or amino groups in total and an organic diisocyanate is applied to at least one side of a fiber substrate and dried. To do.

The invention according to claim 2 is the method according to claim 1, wherein the molecule contains a polyfunctional monomer having at least 3 hydroxyl groups and / or amino groups in the molecule. 0.1 to 4.0 mol% of a polyfunctional monomer having two hydroxyl groups and / or amino groups in total
It is characterized by being used.

According to the invention described in claim 1, as a monomer to be reacted with an organic diisocyanate in the production of a hydrophilic polyurethane resin solution to be applied to a fiber base material in order to obtain a dry moisture-permeable coated cloth, , A polyfunctional monomer having two hydroxyl groups and / or amino groups in the molecule and a polyfunctional monomer having three or more hydroxyl groups and / or amino groups in the molecule in combination In this way, a branched structure is formed in the hydrophilic polyurethane resin so that a non-Newtonian viscous resin solution can be obtained. As a result, the coated fabric coated with this non-Newtonian viscous resin solution has good moisture permeability. It can be waterproof and excellent in workability.

[0012]

BEST MODE FOR CARRYING OUT THE INVENTION In obtaining a dry moisture-permeable coated fabric, a conventional Newton viscous polyurethane resin solution is used immediately after the resin solution is applied to the fiber substrate and before it is put into a dryer for drying. The polyurethane resin solution passes through the base cloth due to the pressure applied to the base cloth by the coating head of the coater, the capillary action of the fibers that make up the base cloth, and the gravity applied perpendicularly to the base cloth surface from the coating surface. Leakage phenomenon occurs. Further, even if the back leakage phenomenon does not occur, the penetration of the resin solution into the base cloth is large in the case of the conventional Newton viscosity polyurethane resin solution, which causes the deterioration of the texture of the cloth and the decrease of the moisture permeability. .

Even if the back leakage phenomenon at the time of processing is eliminated by selecting the base cloth, the coating compound liquid wraps around the back surface of the coater during coating with a floating knife or the like,
The so-called blade leakage phenomenon, which occurs as spots or stripes like foreign matter on the processed fabric as a product, frequently occurs in the case of the Newton viscosity polyurethane resin solution.

However, in the case of using a hydrophilic polyurethane resin solution obtained by using a specific monomer component as in the present invention and having a high degree of branching of the polymer and exhibiting a non-Newtonian viscosity, the viscosity of the base fabric causes Therefore, there is no fear of back leakage, deterioration of texture, deterioration of moisture permeability, etc. Further, there is no blade leakage phenomenon when applying the resin solution, and it is possible to stably produce a processed fabric having good productivity.

As described above, the hydrophilic polyurethane resin solution of the present invention is used as one of the monomer components and a polyfunctional monomer having three or more hydroxyl groups and / or amino groups in the molecule is used. The non-Newtonian viscosity is superior to conventional hydrophilic polyurethane resin solutions in that the increase in crosslink density due to branching of the polymer itself and the degree of entanglement between the molecules in the micro sense and to the base fabric fiber are superior to those of conventional hydrophilic polyurethane resin solutions. It is due to being.

Generally, the viscosity of a polymer solution has the formula S = μD
It is said that the non-Newtonian viscosity given by ⁿ (S: shear stress, μ: non-Newtonian viscosity coefficient, D: shear rate, n: non-Newtonian viscosity index 1>n> 0) indicates the Weisenberg effect. Its effects are complicated and difficult to measure because of the addition of effects such as xyxotropy and viscoelasticity. In the present invention, in order to quantify the non-Newtonian viscosity, the thixotropic index (Thixotrop) is used.
ic Index) measurement value (hereinafter referred to as TI value)
It was adopted.

This measurement is carried out by measuring the viscosity by changing the number of revolutions using a rotational viscometer and calculating the ratio of the two. In the present invention, the BH type rotational viscometer (manufactured by Tokyo Keiki Co., Ltd.) is used. ) Under a constant liquid temperature (30 ° C.), No. 7
The respective viscosities at rotation speeds 2 and 20 were measured with the rotor of No. 2 and the ratio of both was taken as the TI value.

As a result of this measurement, the TI value of the non-Newtonian hydrophilic polyurethane resin solution of the present invention was
It was found to be in the range of 1.10 to 2.00, preferably 1.15 to 1.50. This has a TI value of 2.00
When it is larger than 1, the liquid stability, liquid viscosity and solubility in a solvent are poor, and it is difficult to obtain a uniform resin solution. When it is smaller than 1.10, the non-Newtonian viscosity required in the present invention is low. Since it has not been obtained, it is difficult to obtain the dry moisture-permeable coated cloth having the above-mentioned performance.

In the present invention, as a constituent component for obtaining a hydrophilic polyurethane resin solution having a TI value of 1.10 to 2.00 showing a non-Newtonian viscosity, a monomer capable of reacting with an organic diisocyanate is used in the molecule. This is to use a polyfunctional monomer having two hydroxyl groups and / or amino groups and a polyfunctional monomer having three or more hydroxyl groups and / or amino groups in the molecule.

First, as the polyfunctional monomer having two hydroxyl groups in the molecule, a highly hydrophilic polyalkylene ether glycol having an average molecular weight of 400 to 4000, a polyester polyol having a hydroxyl group at the terminal, and a poly ε-caprolactone polyol. Alternatively, polycarbonate diol or the like may be used alone or as a mixture. And as a polyalkylene ether glycol having a large hydrophilicity,
Examples thereof include polyethylene glycol, polytetramethylene ether glycol, polypropylene glycol, and the like, which are obtained by copolymerizing ethylene oxide, and which have hydroxyl groups at both ends and which have an average molecular weight of 400 to 5000.

As the polyester polyol having a large hydrophilicity, those having a highly hydrophilic alkylene glycol component such as diethylene glycol and saturated dicarboxylic acids dehydrated and condensed to react so that both terminals become hydroxyl groups are used.

Other examples of the polyalkylene ether glycol or polyester polyol which can be used in combination with the above hydrophilic polyol include the following.

That is, as the polyalkylene ether glycol, there are polytetramethylene ether glycol, polypropylene glycol, glycerin propylene oxide adduct, vinyl monomer grafted polyether polyol, etc., and as the polyester polyol, ethylene glycol, butylene glycol, Alkylene glycols such as hexylene glycol, dipropylene glycol, neopentyl glycol and carboxylic acids such as succinic acid, glutaric acid, adipic acid, sebacic acid, maleic acid, fumaric acid, phthalic acid, trimellitic acid Is preferably obtained by reacting to form a hydroxyl group.

Furthermore, it is also possible to use a polyalkylene ether glycol or polyester polyol, which is partially branched and has three or more hydroxyl groups and / or amino groups capable of reacting with an organic diisocyanate in the molecule. And these can also be used individually or in mixture.

The hydrophilic polyurethane resin exhibiting non-Newtonian viscosity in the present invention is prepared by mixing and reacting the above components so that isocyanate groups do not remain at the terminals.
It is desirable to obtain an average molecular weight in the range of 0 to 120,000. The amount of the monomer having 3 or more hydroxyl groups and / or amino groups in the molecule is
Alternatively, it is preferably 0.1 to 4.0 mol% of the monomer having two amino groups. This is because when the amount of the monomer having three or more hydroxyl groups and / or amino groups in the molecule is more than 4.0 mol%, the obtained resin solution lacks liquid stability, liquid viscosity, and solubility in a solvent. It is difficult to obtain a uniform resin solution, and when it is less than 1.0 mol%, the TI value that is a feature of the present invention is 1.10 to 2.
This is because it becomes difficult to obtain a resin solution having a non-Newtonian viscosity of 00.

In addition, a polyfunctional polyisocyanate (for example, Coronate HX or HL manufactured by Nippon Polyurethane Industry Co., Ltd.) is used as an additive in order to improve the adhesiveness to the base cloth.

To apply the non-Newtonian hydrophilic hydrophilic polyurethane resin solution obtained by the present invention to a fiber substrate,
A normal coating method such as a floating knife coater or a roll knife coater may be used, and the coating film thickness is suitably 5 to 100 μm.

A silicone-based or fluorine-based water repellent may be appropriately selected according to the application, and may be performed by a batting method, a coating method, a spray method, or the like.

The dry, moisture-permeable coated fabric of the present invention thus obtained has moisture permeability, water pressure resistance, a soft texture, and a large tear strength, so that it is suitable for sportswear such as golf wear and ski wear, and winter clothes and rain clothes.
