Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wash-resistant silk-based garment which does not cause tangles or the like on the surface even when washed.

[0002]

2. Description of the Related Art Silk fabric has a unique texture, luster, drapability and the like, and has been praised for high-grade clothing for a long time. However, since it is likely to be damaged by friction, it is generally difficult to wash, and dry cleaning is performed under extremely mild conditions.

Recently, however, the present applicant has developed a method for producing a washable silk fabric that can be machine washed by subjecting such a silk fabric to a special resin treatment (Japanese Patent Application No. No. 182957, July 1990
A variety of garments are manufactured from this watchable silk fabric. Hereinafter, these clothes are collectively referred to as wash-resistant silk-based clothes.

[0004]

However, the washable silk fabric, which is the outer material of the above-mentioned wash-resistant silk-based clothing, has the following problems.
Since it has a unique contraction / expansion property that it contracts in the warp direction and expands in the weft direction during washing, it is sewn or glued to the collar, placket, and sleeves of clothing made for shirts, etc. There is a problem that the interlining material shrinks due to shrinkage characteristics different from that of silk which is the outer material and causes trinkage and wrinkling on the outer material.

The present invention has been made in view of the above circumstances, and an object thereof is to provide a wash-resistant silk-based garment which does not cause tugging or the like on the surface even when washed.

[0006]

In order to achieve the above-mentioned object, the laundry-resistant silk clothing of the present invention comprises at least one of an epoxy compound (A), a silicone resin (B), an aminoplast resin and a glyoxal resin. When treated with (C), it has a solubility of 30% by weight or less when immersed in a 5% by weight aqueous sodium hydroxide solution at 65 ° C. for 60 minutes, and the change rate of the softness before washing and that after 10 times of washing is 4 %Less than,
A washable silk fabric having a wash shrinkage of 0 to 3% in the warp direction and a wash shrinkage of -3 to 0% in the weft direction is used for the outer material,
A clothing in which an interlining is bonded to a predetermined part, wherein the interlining has a washing shrinkage rate in the warp direction of 0.1 to 3.0% and a washing shrinkage rate in the weft direction of -2.5 to -0. The construction is such that a woven fabric with a shrinkage characteristic of 1% is used.

[0007]

In other words, the present inventors have conducted a series of studies in order to develop an optimal interlining material for clothing, which uses the watchable silk fabric according to the previous application as the outer material. As a result, when a woven fabric having the above-mentioned special shrinkage characteristics, which is close to the stretch and stretch characteristics of silk fabric, is used as the interlining, the silk fabric as the outer material shrinks in the warp direction and stretches in the weft direction after washing. However, since the interlining is also deformed by the contraction / extension characteristic that is almost similar to this deformation, it is found that the outer material has no trinkles or wrinkles and that the overall shape of the garment is excellent in shape retention. did.

Next, the present invention will be described in detail.

First, the dress material of the present invention is made of a washable silk fabric that has been subjected to a special treatment. This special treatment means that at least one of epoxy compound (A), silicon compound (B), aminoplast resin and glyoxal resin (C) is added to ordinary silk fabric.
No. 3 is fixed, and then the silk fabric is moistened, kept under low tension, and dried by heating.

The above-mentioned epoxy compound is one containing an epoxy group, and a water-soluble type is the most preferable in the process. Examples of the water-soluble epoxy compound include ethylene glycol, polyethylene glycol, propylene glycol, polypropylene glycol, glycerin, sorbitol, polyglycerol, pentaerythritol, tris (2-hydroxyethyl) isocyanurate, trimethylolpropane, neopentyl glycol, phenol ethylene. Oxides, lauryl alcohol, and mono- and polyglycidyl ethers of ethylene oxide. Among them, ethylene glycol, polyethylene glycol,
Polyglycidyl ethers such as propylene glycol, polypropylene glycol, phenol ethylene oxide, lauryl alcohol ethylene oxide, glycerol and polyglycerol, and polyglycidyl ethers such as polyglycerol are preferable, and ethylene glycol diglycidyl ether and polyethylene glycol diglycidyl ether are particularly preferable. Optimal in terms of effectiveness. However, these compounds may be used alone or in combination of two or more kinds. As the catalyst, for example, when ethylene glycol diglycidyl ether is used, sodium chloride, diethylenetriaminepentaacetic acid 5 sodium, etc. are suitable.

As the above-mentioned silicone resin, silicone elastomer can be mentioned, and among them, epoxy modified silicone, amino modified silicone, polyether modified silicone and rubber silicone are preferable from the viewpoint of feeling. In particular, rubber silicone is preferable because of its compatibility with the epoxide, and terminal diol type rubber silicone is most preferable. However, these silicone resins may be used alone or in combination of two or more kinds.

Further, as the aminoplast resin, melamine formalin resin, triazine formaldehyde resin, urea diformaldehyde resin, ethylene urea formaldehyde resin, other N-methylol resin, N
-Methylol ether resins and the like are mentioned, and among them, melamine formalin resins are preferable in terms of texture and durability. These may be used alone or in combination of two or more.

Examples of the glyoxal resin include dimethylol-dihydroxy-ethyleneurea resin and tetramethylol-acetylene diurea resin, which may be used alone or in combination of two or more kinds.

As a method for fixing the above three members to a silk fabric, for example, first, the epoxy compound is made into an aqueous solution or a dispersion liquid, and the dipping method, the pad dry steam method,
The pad dry dry bake method, the cold batch method, etc. are applied, and then the silicone dry resin (B) and the aminoplast resin and / or glyoxal resin (C) are made into an aqueous solution or a dispersion liquid and the pad dry dry bake method or the like is applied. There is a method of applying.

The silicone resin (B) and the aminoplast resin and / or glyoxal resin (C) are
It can also be given individually. However, in this case, it is preferable that the silicone resin (B) is applied first.

After the above three (A) to (C) are applied to the silk fabric, the silk fabric is dried and heat-treated to cure the resin component. The conditions at this time are 140 to 180 ° C.
It is preferably set to about 0.5 to 2 minutes.

The concentration of the aqueous solution or dispersion of the above three (A) to (C) is preferably 70 to 400 g / l for the epoxy compound (A) in the case of the padding method,
Above all, 100 to 300 g / l is most suitable, 5 to 50 g / l is preferable for the dipping method, and 10 to 40 g / l is particularly preferable.
l is optimal. In addition, the silicone resin (B) is 3 to
30 g / l is preferable, 5 to 55 g / l is most preferable, and 1 to 20 g / l is preferable for aminoplast resin and glyoxal resin (C), and 2-1 is especially preferable.
5 g / l is optimal. Outside these concentration ranges,
It is not possible to obtain a product having a sufficient anti-rubbing effect, a moisture anti-wrinkle effect, and a soft texture.

The amount of these resins deposited on the silk fabric is preferably set to ³ to 12 g / m ² as solid content. This is because if the adhesion amount is less than this range, sufficient washing durability cannot be obtained, and conversely if it is too large, the original texture of silk tends to be impaired.

In the present invention, the silk woven fabric to which the resin has been applied and dried and fixed in this way is held at a low tension in the final heating and drying step after wetting with water or an aqueous liquid. dry.

As a method of maintaining a low tension on the silk fabric, specifically, for example, when the fabric is supplied to a dryer, the amount of shrinkage or unevenness of the fabric is detected to change the supply speed. It is possible to supply the woven fabric together with the air flow. Further, since the drying treatment tends to have a high tension due to the drying shrinkage effect of the woven fabric, particular caution is required, and it is important to perform the treatment more gently than usual.
As such a drying device, it is preferable to use a short loop dryer or a net-shaped dryer which has been modified as described above. When the drying process is performed in this manner, dimensional stability is obtained due to sufficient shrinkage.

After the drying step, the above silk fabric was heated to 140-
The final product may be heat-set at about 170 ° C for about 30 to 60 seconds and combined with a semi-decatizer steamer or calendering to make the final product. As mentioned above, these steps are also kept under low tension. It is preferable to do it as it is. In addition, it is preferable that the width is limited to a minimum amount of 0 to 3%.

The silk fabric obtained in this manner was treated with a 5% by weight aqueous sodium hydroxide solution at 65 ° C. for 6 hours as described above.
Solubility when soaked for 0 minutes is 30% by weight or less, change rate of bending resistance before washing and bending resistance after 10 times of washing is 4% or less, and shrinkage rate in washing is 0 to 3% in the longitudinal direction. It becomes -3 to 0% in the weft direction. Therefore, it can be seen that this silk fabric tends to shrink slightly in the warp direction and stretch in the weft direction after washing.

The laundry-resistant silk-based garment of the present invention is obtained by cutting the silk fabric thus obtained according to a usual method,
It can be obtained by applying an interlining to a necessary portion such as a collar portion, a placket portion, and a sleeve portion, and stitching it, or adhering it and sewing it into a shape such as a shirt blouse or a dress.

The interlining has a washing shrinkage of 0.1 to 3.0% in the warp direction and a washing shrinkage of -2.5 to-in the weft direction.
It is necessary to have shrinkage properties that are 0.1%. If it does not have this shrinkage property, it cannot follow the shrinkage property of the silk fabric as the outer material. As the material of the woven fabric, filament yarn such as polyester fiber, polyamide fiber, polyacrylonitrile fiber or crimped yarn is suitable. Further, it is convenient to use a woven fabric coated with a thermoplastic adhesive on one side. That is, this can be easily attached to the back side of the outer material by heating with an iron.

As such an interlining material, ET10 (manufactured by Tokai Thermo Co., Ltd.) which is a commercial product is most suitable. This product has hitherto been used as an interlining material for nit products, and has never been used as an interlining material for clothing made of woven fabric.

Next, examples will be described.
