Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a napped fabric, and more particularly, to a napped fabric having no pile of napped fibers on a pile surface even when washed at home and having hygroscopicity.

[0002]

2. Description of the Related Art In recent years, in the field of napped fabrics, especially in the field of blankets, a Meyer blanket made of spun yarn of synthetic fibers, in particular, acrylic synthetic fibers has become mainstream. However, the napped fabric made of synthetic fibers has problems such as low hygroscopicity, stickiness due to perspiration, and discomfort. In order to solve the above problem, a raised fabric using a spun yarn mixed with a cellulose fiber having hygroscopicity for a pile has been proposed. For example, Japanese Patent No. 2924145 discloses a mixed spinning wherein 50 to 80% by weight of hydrophilic fiber staples such as cotton, hemp and viscose rayon and 50 to 20% by weight of hydrophobic fiber staples such as polyester fiber and acrylic fiber are mixed. A pile fabric having a cut pile of yarn and having a length of hydrophilic fiber longer than a length of hydrophobic fiber by 1 mm or more is disclosed. Since this pile fabric is made by blending hydrophilic fibers, the pile fabric has improved moisture absorption, tackiness due to perspiration is improved, and a comfortable feel can be exhibited. However, when this pile fabric is washed at home, there has been a problem that hydrophilic fibers converge and adhere to each other to form a brush tip, making the skin feel poor and aesthetically impaired.

[0003] The cause of the problem of the pile fabric is firstly due to the intrinsic properties of the hydrophilic fiber that when the hydrophilic fiber absorbs moisture, the fibers are bundled together and easily adhered when dried. Secondly, a large amount of 50-80% by weight of hydrophilic fibers that converge when water is absorbed and easily adhere, and thirdly the length of the hydrophilic fibers constituting the cut pile Is longer than the hydrophobic fiber by 1 mm or more, so that substantially only the hydrophilic fiber is present on the pile surface, and the bundle and adhesion of the fiber are very likely to occur.

[0004]

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned problems of the prior art, improve the discomfort caused by stickiness of a nap cloth made of 100% synthetic fiber, and improve the nap when washed at home. It is an object of the present invention to provide a napped fabric that prevents convergence and adhesion to form a brush tip, has a low frictional voltage, is excellent in heat retention, and can maintain a soft texture.

[0005]

The invention claimed in the present application is as follows. (1) A raised fabric in which a blended yarn of cellulosic fiber and synthetic fiber forms a pile, wherein the number X of cellulosic fibers and the number Y of synthetic fibers in the blended yarn are 30 ≧ Y / X ≧ 2.
Characterized in that the pile surface of the napped fabric is clean-cut. (2) The average fineness of the cellulosic fiber is 5.5 dte.
x. The napped fabric according to (1), which is not more than x. (3) The raised fabric according to (1), wherein the average fineness of the synthetic fibers is 3.3 dtex or less. (4) The raised fabric according to (1) or (3), wherein the synthetic fiber is an acrylic fiber.

[0006] In the napped fabric according to the present invention, a pile is formed by a mixed spinning of cellulosic fibers and synthetic fibers. The cellulosic fiber is not particularly limited as long as it can be blended with a synthetic fiber, and examples thereof include cotton and regenerated cellulosic fiber. As the regenerated cellulosic fiber, rayon, polynosic, Tencel (purified cellulose fiber, trade name of Akzo Nobel), lyocell (purified cellulose fiber), Bemberg (cupra, trade name, manufactured by Asahi Kasei Corporation), acetate and the like are used. Of these, rayon, polynosic rayon, Bemberg, acetate, lyocell, newcell, etc. are preferred from the viewpoint of increasing the average fiber length and reducing the loss of fibers during processing of the nappied fabric.

[0007] Rayon is preferred because it can easily increase the average fiber length and can be obtained relatively inexpensively, and cotton is preferably used because it can be obtained at low cost. In the case of dyeing only synthetic fibers in printing or anti-dyeing of a nap-up fabric, it is preferable to use bright to help the sharpness. Further, the above-mentioned cellulosic fibers may be used singly, or a mixture of several kinds of fibers having different fineness, cross section and degree of imparting function may be used. In addition, the average fineness of the cellulosic fiber is from the viewpoint of preventing the texture of the nappi fabric from lowering.
It is preferably 5.5 dtex or less, more preferably 3.3 dtex.
dtex or less.

The synthetic fiber is not particularly limited, and examples thereof include polyester fiber, nylon fiber, acrylic fiber, and polypropylene fiber. These synthetic fibers may be used alone, or may be a composite of these fibers. It is preferable that shrinkable acrylic fibers are included from the viewpoint of the texture of the nappied fabric and the point that the spun yarn is easily dyed into a bulky yarn. The average fineness of the synthetic fiber is preferably 3.3 dtex or less, more preferably 2.2 d, from the viewpoint of preventing the texture of the nappied cloth from lowering.
dtex or less.

In the present invention, the blended yarn comprising the above-mentioned cellulosic fiber and synthetic fiber can be obtained by a known method, but the relationship between the number X of cellulosic fibers and the number Y of synthetic fibers is 30 ≧ Y / X ≧ 2, preferably 20 ≧ Y / X ≧ 3
Must be in the range of The above relational expression between X and Y indicates how much the synthetic fiber surrounds the cellulosic fiber. When Y / X is less than 2, the use amount of the cellulosic fiber is large, and when the napping fabric is washed, the napped surface fibers are bundled by drying, the adhesive state becomes strong, and the morphological change such as a brush tip shape is caused. Easy to occur. Y /
When X exceeds 30, the amount of synthetic fibers used is large, and it is difficult to secure the hygroscopicity of the nappied fabric. Further, in order to obtain a typical bore or Meyer as a raised fabric, it is preferable to use a spun yarn as a raw material that shrinks in hot water and exhibits bulkiness. Those that do not exhibit bulkiness are less likely to produce a volume feeling and are likely to be heavy fabrics. A spun yarn having such shrinkage can be obtained, for example, by blending 30 to 70% by weight of shrinkable acrylic fibers having a shrinkage of 15 to 35%.

[0010] The napped fabric of the present invention can be obtained by a known method using the spun yarn as a pile yarn.
The ground yarn other than the pile yarn is not particularly limited, and polyester fibers are generally used. Moreover, the piled surface in the present invention needs to have the pile surface uniformly clean-cut (so-called trimmed). Generally, cellulosic fibers are non-shrinkable, and when combined with shrinkable acrylic fibers, cellulosic fibers tend to be unevenly distributed on the surface layer of the napped fabric, and the cellulosic fibers come into contact at the tip of the nap by washing. The fibers on the nap surface are bundled and adhered to each other to form a brush tip. Therefore,
In order to prevent such a phenomenon, it is important to uniformly clean-cut the napped surface.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described specifically with reference to examples. In addition, the evaluation of the texture and washability in the examples, and the measurement of static electricity were performed by the following methods. Texture: Determined as follows by sensory evaluation by five panelists. ◎ Very good ○ Good △ Moderate × Bad Washability: After washing continuously 5 times in accordance with JIS-L-0217, take out pile from naturally dried napping cloth, observe pile form, and see FIG. The grade was determined as a comparison with the side view photograph of the reference pile for grade determination shown. Static electricity: According to the JIS-L-1094 method, the withstand voltage against a cotton cloth was measured.

Examples 1 to 4 and Comparative Examples 1 to 4 Shrinkable acrylic fibers and non-shrinkable acrylic fibers (both made by Asahi Kasei Kogyo Co., Ltd.) having a fineness (dtex) shown in Table 1 were used as pile yarns. A spun yarn (meter count: 2/36 s (390/220)) obtained by blending rayon fibers having a fineness (dtex) shown in (1) at a predetermined weight ratio was used. Polyester fibers (110 dtex / 24f) were used as the inlay yarn and the chain yarn. Using the above yarns, a blanket is knitted using a Karl Meyer double Russell machine (total packing, 16GG, pot length 22mm, 18
C / inch), dyeing, washing with water, and drying, followed by brushing, shearing, polishing, and shearing to prepare various Meyer blankets in which the nap of the blanket was clean-cut. The characteristics of each blanket obtained were examined, and the results are shown in Table 1. The blankets obtained in Examples 1 to 4 are all excellent in heat retention, friction withstand voltage, hand and washability. However, in Comparative Examples 1 to 4, blankets excellent in all of the above characteristics could not be obtained.

[0013]

[Table 1]

Comparative Example 5 A blanket having a raised surface with irregularities was prepared in the same manner as in Example 2 except that the uneven cut was finished in the process of manufacturing the blanket. The characteristics of the blanket thus obtained were examined. As compared with the clean-cut blanket of Example 2, the hand and the friction band voltage were the same, but the washability was inferior and at the second level.

[0015]

The raised fabric of the present invention uses a spun yarn obtained by mixing two types of fibers, a cellulosic fiber and a synthetic fiber, at a specific ratio as a pile yarn, and the pile surface is clean-cut. Therefore, when the napping fabric is washed, the fibers converge and can be prevented from adhering to form a brush point, and the hygroscopic property and comfortable feeling of the cellulose fiber and the heat retention property of the synthetic fiber. It can have a sense of volume.
