Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a feather having excellent water repellency, water resistance, moisture release, heat retention, and oil absorption.
An object of the present invention is to provide a novel water-repellent treatment composition for clothing which is environmentally friendly because it is a natural product and which is provided with design properties including post-printing and a coated product thereof.

2. Description of the Related Art Conventionally, Japanese Patent Application Laid-Open Nos. 10-266053 and 10-31 disclose a method utilizing fine feather powder.
No. 0962, a feather fiber entangled nonwoven fabric, a method for producing the same, a heat insulating material using the nonwoven fabric, a humidity control material, and a water entangled feather fiber-containing oil absorbing nonwoven fabric are known.

[0003] However, these methods are a method in which feather fibers and pulp fibers are simultaneously made and composited, and therefore have a drawback that they cannot be easily coated by post-treatment. on the other hand,
A method of coating a corrugated cardboard or the like with feather fine powder and a special chemical has been proposed. However, there is no proposal for a method of coating a cloth, a non-woven fabric, a fiber, or the like, which is mainly made of a paper substrate and used for clothing.

[0004] On the other hand, a method of treating with a wax or the like is known. These methods can maintain water repellency, but have poor adhesion to fibers. Also, treatment of silicon or the like has been proposed. Although this technique is a method having high water repellency while maintaining a hand, it tends to be inferior in heat retention and adhesion when printing later.

[0005]

In particular, the texture is important when coating on clothing, and it is difficult to maintain the texture only by a resin coating method. The point is how to reduce the amount of the binder and fix it to the fiber. The present invention has excellent water repellency, water resistance, moisture release, heat retention, and oil absorbency of feathers, and furthermore, imparts design properties including post-printing, and is a natural water-repellent new water repellent for clothing. The present invention provides a treatment composition and a coated product thereof.

[0006]

According to a first aspect of the present invention, there is provided a garment comprising at least 5 parts by weight to 500 parts by weight of fine feather powder based on 100 parts by weight of the solid content of the resin composition. It is a new water repellent treatment composition for use.

In a second aspect, the resin composition comprises an acrylic resin, a rubber resin, a urethane resin, an olefin resin,
The novel water-repellent composition for clothing according to the first invention, which is a resin composition comprising at least one or more epoxy-based resins.

The third invention is characterized in that the feather fine powder is 1 μm to 5 μm.
The novel water-repellent composition for clothing according to the first or second invention, wherein the composition has a thickness of 00 μm.

A fourth invention is a coated article using the novel water-repellent composition for clothing according to either the first invention or the third invention.

[0010]

BEST MODE FOR CARRYING OUT THE INVENTION According to the present invention, it is possible to maintain texture and water repellency by a conventional pigment printing technique using a printing method and an application technique using feather fine powder.

More specifically, a resin composition having a solid content of 100
At least 5 parts by weight of fine feather powder to 5 parts by weight
Although it can be used in the range of 00 parts by weight,
If the amount is less than the weight part, excellent water repellency, water resistance, moisture release and heat retention of the feather cannot be obtained. If the amount is more than 500 parts by weight, the adhesive force of the fine feather powder when coated is inferior.

The resin used here can be a resin composition comprising at least one of acrylic resin, rubber resin, urethane resin, olefin resin and epoxy resin. As the resin type, any of a solvent type, an aqueous type and a non-solvent type can be used, but the aqueous type is preferred from the viewpoint of the environment and the feeling as a garment. In particular, the emulsion type is more preferable in the aqueous type.

The acrylic resin emulsion type can be easily obtained by ordinary emulsion polymerization. That is, it can be obtained using water, a monomer having an α, β unsaturated double bond, an emulsifier, and a polymerization initiator. Examples of the monomer having an α, β unsaturated double bond include an alkyl (meth) acrylate having 1 to 14 carbon atoms, a carboxyl group, a hydroxyl group, an epoxy group, an amino group, an alkoxylyl group, an amide group, and the like. (Meth) acrylic acid ester can be used.

As the emulsifier, nonionic, anionic,
Cationic emulsifiers can be used. In the present invention, the polymerizable emulsifier can be selected from the viewpoint of copolymerizability with a monomer, monomer-emulsifiability, and dispersion stability of polymer particles. As a polymerizable emulsifier, a surfactant having an allyl group, a (meth) acrylic acid group, a styrene group, or an isopropenyl group in a molecule as a polymerizable group is known, and these may be used as the emulsifier of the present invention. it can.

If the amount is less than 0.1% by weight, a stable emulsion polymer cannot be obtained, and there are many aggregates. If it is 5% or more, it is difficult to obtain the water repellent effect of the feather fine powder.

Examples of the polymerization initiator used herein include t-butyl hydroperoxide, benzoyl peroxide, potassium peroxodisulfate, ammonium peroxodisulfate, an azo polymerization initiator, and a reducing agent,
For example, a redox polymerization initiator combining ascorbic acid, sodium bisulfite, iron ions and the like is appropriately used. As the polymerization method, a usual monomer-dropping method, a monomer-
At polymerization temperature of 40 ° C to 90 ° C by emulsion dropping method, etc.
The emulsion polymerization product is obtained by heat polymerization for about 5 hours.

Examples of the rubber-based resin include styrene-butadiene emulsion, nitrile-butadiene emulsion, butadiene emulsion, and acryl-modified rubber emulsion.

Examples of the urethane resin include a method using a monomer having a sulfone group in the polyol component and a polyol component having a large number of moles of ethylene oxide added thereto, and a method of introducing a carboxyl group with an acid anhydride after forming a urethane bond. Aqueous conversion is possible.

Examples of the olefin resin include an ethylene copolymer emulsion and an α-olefin / maleic anhydride copolymer resin.

Bisphenol A is used as the epoxy resin.
Epoxy resin with a skeleton as a skeleton is mechanically emulsified and dispersed in the presence of an emulsifier, an epoxy resin emulsion modified with a water-soluble acrylic resin, an epoxy resin emulsion modified with an acid anhydride, an ethylene oxide-added epoxy resin, and the like. Can be

Further, if necessary, a curing agent such as an aziridine type, a melamine type, a phenol type, a blocked isocyanate type, a metal cross-linking type or a ketone / hydrazide type can be used.

On the other hand, the feather fine powder used here is obtained by milling with a grinding wheel having a clearance of 1 to 500 μm. When the thickness is 1 μm or less, the number of feather-branched fibers is relatively small, so that the heat retention after coating is reduced. On the other hand, if it is 500 μm or more, when printing is performed on the coated surface after coating, the finish of the printed surface is reduced. However, the size is not necessarily limited in consideration of designability and the like.

The above composition can be coated by a screen coating method, a spraying method, an impregnation method, a roll coater method, a gravure coating method, or the like. As a method, a printing method by a pigment printing method is preferable. The printing method is basically screen coating, but use a thixotropic reducer obtained by emulsifying a high-boiling hydrocarbon solvent with an emulsifier to increase the viscosity to several centipoise or more to make screen coating easier. Is preferred. Since the effect of the reducer can be screen-coated even with a small amount of the resin component, it is effective from the viewpoint of texture, especially when applied to clothing fibers.

Further, as an application of the application of fine feather powder, a method of coating moisture-permeable urethane on a cloth of nylon, polyester, or the like is known, and a method of coating these materials with fine feather powder is also effective. It is. On the other hand, the fabric dyed with the natural pigment safflower has an effect on the heat retention, and the method of coating the fabric dyed with the safflower is also effective on the heat retention.
