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 a hygroscopic property.

[0002]

2. Description of the Related Art In recent years, in the field of napped fabrics, particularly in the field of blankets, a Meyer blanket made of a spun yarn of synthetic fibers, in particular, acrylic synthetic fibers has become mainstream. However, the napped fabric made of a synthetic fiber has a problem that it has a low hygroscopic property and causes stickiness due to sweating, thereby giving discomfort. In order to solve the above problem, a raised fabric using a spun yarn mixed with cellulose fibers 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 is improved in moisture absorbency, 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 impairing the appearance.

[0003] The cause of the problem of the pile fabric is firstly due to the inherent characteristics of the hydrophilic fiber that when the hydrophilic fiber absorbs moisture, the fibers are bundled together and easily adhere when dried. Secondly, a large amount of 50-80% by weight of hydrophilic fibers that converge when absorbing moisture 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.

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

[0005]

The invention claimed in the present application is as follows. (1) A raised fabric in which a blended yarn of cellulosic fibers (excluding fibers containing sulfur) and synthetic fibers forms a pile,
The number X of cellulosic fibers and the number Y of synthetic fibers in the blended yarn are in the range of 30 ≧ Y / X ≧ 2, and
The average fineness of the base fiber is 5.5 dtex or less,
The average fineness of the fibers is 3.3 dtex or less, and the pile surface of the napping cloth is uniformly cut and clean-cut, and the washing resistance when washed according to JIS-L-0217 method is 4 or more. A napped fabric, characterized in that: ( 2 ) The raised fabric according to (1) , 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 (excluding fibers containing sulfur) and synthetic fibers. The cellulosic fiber is not particularly limited as long as it can be blended with a synthetic fiber. For example, cotton or regenerated cellulosic fiber is used. 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 Kogyo Co., Ltd.), acetate and the like are used. Among these, from the viewpoint of increasing the average fiber length and reducing the dropout of fibers during processing of the nappied fabric,
Rayon, polynosic rayon, Bemberg, acetate, lyocell, newcell and the like are preferred.

[0007] Rayon is preferred from the viewpoint that the average fiber length is easily increased and can be obtained at relatively low cost, and cotton is preferably used from the viewpoint of being obtainable at low cost. In the case of dyeing only synthetic fibers in printing or anti-dyeing of a nap-clothed 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 function imparting may be used. In addition, the average fineness of the cellulosic fiber is from the viewpoint of preventing the texture of the napped fabric from lowering.
It must be 5.5 dtex or less , preferably 3.
3 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. In addition, the average fineness of the synthetic fibers must be 3.3 dtex or less from the viewpoint of preventing the texture of the napped fabric from lowering.
2dtex or less.

In the present invention, the blended yarn comprising the cellulose-based fiber and the synthetic fiber can be obtained by a known method, but the relationship between the number X of the cellulosic fiber and the number Y of the synthetic fiber is 30 ≧ Y / X ≧ 2, preferably 20 ≧ Y / X ≧ 3
Must be within the range. The relational expression between X and Y indicates the extent to which the synthetic fibers surround the cellulosic fibers. When Y / X is less than 2, a large amount of the cellulosic fiber is used, and when the nap cloth is washed, the fibers on the nap face are bundled by drying, the adhesive state becomes strong, and the morphological change such as a brush tip is caused. Easy to occur. Y /
When X exceeds 30, a large amount of synthetic fiber is used, and it is difficult to secure the hygroscopicity of the napped fabric. Further, in order to obtain a typical bore or Meyer as a raised fabric, it is preferable to use a material in which a spun yarn as a raw material contracts in hot water and exhibits bulkiness. Those that do not exhibit bulkiness are less likely to give a volume feeling and tend 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%.

The napped fabric of the present invention can be obtained by a known method using the above spun yarn as a pile yarn.
The ground yarn other than the pile yarn is not particularly limited, and generally, a polyester fiber is used. Moreover, the piled surface in the present invention requires that the pile surface is 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 gathered and adhered to form a brush tip. Therefore,
In order to prevent such a phenomenon, it is important to uniformly clean-cut the napped surface.

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

Examples 1 to 4 and Comparative Examples 1 to 4 As pile yarns, shrinkable acrylic fibers and non-shrinkable acrylic fibers having a fineness (dtex) shown in Table 1 (both manufactured by Asahi Kasei Kogyo) and Table 1 A spun yarn (meter count: 2/36 s (390/220)) obtained by blending rayon fibers having a fineness (dtex) shown in Table 2 in a predetermined weight ratio was used. Polyester fibers (110 dtex / 24f) were used as the inlay yarn and the chain yarn. Using the above yarn, a blanket is knitted using a Karl Meyer double Russell machine (total packing, 16GG, pot distance 22 mm, 18
C / inch), dyeing, washing with water, and drying, followed by brushing, shearing, polishing, and shearing, to produce 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 were all preserved.
Humidity resistance, friction voltage resistance, is excellent in texture and washing resistance, but in Comparative Examples 1-4, it was not possible to obtain an excellent blanket all the above characteristics.

[0013]

[Table 1]

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

[0015]

The raised fabric of the present invention has a specific average fineness.
A spun yarn obtained by mixing two types of fibers, cellulosic fibers (excluding sulfur-containing fibers) and synthetic fibers, at a specific ratio is used as a pile yarn, and the pile surface is evenly cut and clean-cut. Since the washing resistance is higher than or equal to 4 grades, it is possible to prevent the fibers from converging and bonding to form a brush when washing the napped fabric, and to improve the moisture absorption and feel of the cellulose fibers. It can have the comfort and the heat retention and volume feeling of synthetic fibers.
