Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a nubuck upholstered blanket, and more particularly to a nubuck upholstered blanket suitable for flocked clothing.

[0002]

2. Description of the Related Art The flocking process of applying an adhesive to the surface of a fabric and planting short fibers (pile) has been carried out for a long time, but most of the flocking process is performed by an electrostatic flocking process which can be manufactured relatively inexpensively. Most of them are the mainstream, and the obtained fabric has a nubuck-like excellent appearance. However, since the conventional flocked fabric is not sufficiently durable even if it is electrostatic flocked fabric, not only the nubuck-like texture is significantly deteriorated due to friction and impact, but also the pile However, there is a problem in that the appearance of the cloth that has been hair-removed and flocked is impaired. Particularly when applied to clothing, there is a problem that an unexpected external force is often applied when putting on and taking off or wearing, and the appearance is significantly impaired.

[0003]

SUMMARY OF THE INVENTION It is an object of the present invention to solve the above-mentioned problems of the prior art and to provide a nubuck upholstered blanket excellent in abrasion resistance, appearance and texture, which is particularly suitable for clothing applications. is there.

[0004]

According to the present invention, a length of 0.2 to 0.4 mm and an average fineness of 0.1 are formed on a surface of a base fabric having a thickness of 2 mm or less with an adhesive layer having a thickness of 0.5 mm or less. The present invention relates to a nubuck-like upholstered woolen fabric in which napped hair composed of cellulose fibers having a denier of 5 to 2.0 is provided by electrostatic flocking.

The base fabric used in the present invention is not particularly limited as long as it has a thickness of 2 mm or less, preferably 0.1 to 2.0 mm, and more preferably 0.2 to 1.0 mm. Any fabric such as a non-woven fabric and a knitted fabric can be used. Also, there is no particular restriction on the material, nylon,
Synthetic fibers such as polyester, regenerated fibers such as viscose rayon and cuprammonium rayon, natural fibers such as cotton, hemp, and wool, or mixed fibers thereof can be used.
Further, a cloth obtained by interwoven or interwoven synthetic fibers and natural fibers can also be used. When the thickness of the base fabric exceeds 2.0 mm, the base fabric is too thick and the texture is deteriorated, and it becomes difficult to sew or mold. If the thickness is less than 0.1 mm, the base fabric may be too thin and the rate of defective products such as breakage may increase.

The adhesive used in the present invention is not particularly limited as long as it has excellent adhesiveness to both the base cloth and the cellulosic fiber, and a known adhesive may be appropriately selected depending on each material. used. Examples of such an adhesive include urethane adhesives and acrylic adhesives. From the viewpoint of the texture of clothing, the adhesive strength to fibers, etc., a urethane adhesive was mixed with an acrylic adhesive for clothing. Those are preferably used. The thickness of the adhesive layer is 0.5 mm or less, preferably 0.1 to 0.5 mm, more preferably 0.1 to 0.3 mm. The adhesive layer preferably has a thickness as uniform as possible and is preferably not foamed.
If the thickness of the adhesive layer exceeds 0.5 mm, the amount of the adhesive applied becomes excessive and the texture of the garment is deteriorated, making it difficult to sew or mold and to reduce the economical efficiency. If the thickness of the adhesive layer is less than 0.01 mm, the pile amount of the cellulosic fibers may be easily removed due to the insufficient amount of the adhesive applied.

Cellulosic fibers used in the present invention include regenerated fibers such as cellulose fibers and viscose rayon. Particularly, regenerated fibers such as viscose rayon are excellent in abrasion resistance and dyeability and have a texture. It is also preferred because it has a nubuck-like smooth, slimy feel and a luxurious feel. The average fineness of the cellulosic fiber is 0.5 to 2.0 denier, preferably 0.8 to 1.0 denier. When the average fineness is less than 0.5 denier, the pile strength is low and it is difficult to cut the pile uniformly. If it exceeds 2.0 denier, the pile density will decrease, and the nubuck appearance will be slightly impaired.
The touch is also reduced.

The cellulosic fiber has a content of 0.2 to 0.4.
It is used after being cut into short fibers (pile) having a length of mm, preferably 0.22 to 0.35 mm, more preferably 0.225 to 0.25 mm. If the pile length is less than 0.2 mm, the wear resistance is poor, and the pile is scraped and falls off, and the appearance is significantly impaired. If the pile length exceeds 0.4 mm, the nubuck-like texture is lost, and when touching or touching something with the hands, the pile's coat of hair collapses and appears discolored, causing problems such as appearing whitish. The cutting of fibers is generally performed by using a push-cut guillotine cutter and wetting the fibers with water. There are a method of cutting after dyeing the fiber and a method of cutting after dyeing, and either method may be adopted. After cutting, screen mesh is used to remove miscuts. After dyeing,
It is treated with an electrodeposition treatment agent such as silica or salts in order to increase the dielectric constant and improve the flight properties of the pile.

The pile composed of the above-mentioned cellulosic fibers is planted in a napped state on a base cloth having an adhesive layer by a known electrostatic flocking method. FIG. 4 shows a general electrostatic flocking device. In the figure, an electrostatic field is created between a positive electrode 5 and a negative electrode 6 provided at the bottom of the pile dropping device 4 in which the pile 3 is stored, and a positive charge is applied to the pile 3 to move the pile 3 along the lines of force. And propel it downwards at high speed. Then, the pile 3 sticks on the adhesive layer 2 on the base cloth 1 which moves horizontally above the negative electrode 6, and stands on the base cloth. The base cloth 1 with piled piles is guided to an electrostatic suction device 7 and an electric suction 8 installed downstream of the pile to remove excess pile. For example, a voltage of 10 to 100 KV is applied between the electrodes 5 and 6 to form a magnetic field, and thus the pile 3 is planted on the adhesive layer 2. As for the napped state of the pile 3, when the pile is upright, the wear resistance is better, and the appearance and texture of a nubuck tone are also excellent.

That is, the flocked cloth is cut out into a circle with a diameter of 3.9 cm, and a standard friction cloth (cardboard cloth) is applied with a pressing load of 9 KPa to rub it in multiple directions 500 times, 1000 times and 1500 times, and after rubbing, The appearance change was evaluated according to the following three grades. ○: No change from before friction. Δ: The pile was scraped off slightly, and the base cloth was slightly exposed. X: The pile was almost scraped off and the base cloth was exposed.

(2) Standing state The cross section of the flocked fabric is magnified 75 times with a scanning electron microscope to take an electron micrograph, and the standing state of the pile is observed and evaluated in the following three stages. did. ○: Good (the pile is upright and the pile coat is even). Δ: Slightly good (in the intermediate state between ○ and ×). X: Poor (the piles are tilted obliquely and intersect with each other and are disturbed, and the pile hairs are also uniform). (3) Texture ◯: Excellent in nubuck texture, smooth and slimy. B: Somewhat lacking in nubuck-like texture and slightly smooth with a feeling of roughness. X: There is no nubuck-like texture at all, and the texture is remarkable. (4) Color tone ◯: Excellent. B: Good. X: Inferior
