Description

  The present invention relates to a cover for bedding having excellent stretchability.

  Currently, hotels use a single sheet of cloth to wrap a bed mattress when making a bed. Also, in ordinary households, bed making has been performed in accordance with the method conventionally used in hotels. However, this method is very time consuming. Under such circumstances, a sheet was devised in a box shape without a bottom, and rubber was sewed on the outer periphery (bottom of the side surface), and now this type of bed sheet for general households has become the mainstream. ing.

  By the way, in the modern society, various sizes of beds and mattresses for beds are being sold in consideration of the problem of housing conditions in addition to various lifestyles and various heights of people. . As an example, the size of a mattress for a single size bed will be described. In Japan, the size of a housing complex is about 90cm x 195cm x 18cm, but for those who want a relaxing sleeping life. The so-called single wide long size provided in is about 110 cm × 215 cm × 18 cm. Thus, even those that fall within the category of single-size bed mattresses have a difference of 20 cm in width and 20 cm in length between large and small. Moreover, even if the height of the bed mattress is high, some products provided for those who seek cushioning have a height of about 40 cm. In this way, it is a burden for furniture stores, bedding stores and bedding departments to arrange various sizes of bed sheets according to the size of various bed mattresses. There is a risk of purchasing the wrong item.

  Currently, not only bed mattresses but also futons of various sizes are on sale. It is a burden for bedding stores and bedding departments to arrange various sizes of wrappings according to the size of such various futons, while consumers mistakenly choose items that do not fit the size. There is a risk of purchasing. Moreover, in the case of a wrapping cloth, if it is made of cotton, for example, it may shrink due to washing, become short in length, and may not be usable.

  In recent years, there has been an interest in getting good quality sleep. Pillow size, height, and shape are important for good quality sleep. Pillows with specific curvilinear shapes that have been studied from an ergonomic perspective are available on the market or made to order. It is getting to be. However, it is difficult to manufacture a pillow case (pillow cover) that fits a pillow having such a curved shape if a normal fabric (cloth) is used, and a box-type pillow case is used instead. There is.

  Patent Document 1 discloses a stretchable yarn in which a splicing yarn and a stringing yarn are arranged around an elastic yarn. Patent Document 1 describes that such a stretchable thread is used for clothing such as socks.

  Non-Patent Document 1 is a product guide for a covered yarn called “Marlon (registered trademark)”. According to this, the use of the covered yarn is socks, pantyhose, tights, and the like.

  As described above, there are various sizes of bedding, and various types of bedding are sold because it is necessary to match the size of the bedding. The inventors of the present invention have considered that developing bedding that can be used for various sizes of bedding eliminates the problem of store assortment and the problem of consumer mis-purchase. In addition, the inventors considered that the above-described stretchable yarn could be used for manufacturing such a bedding. And if we developed a stretchable bedding using stretchable yarn, we thought that we could solve the problem that wrapping and the like could not be used due to shrinkage in washing.

  Further, the present inventors considered that a pillow case is manufactured by using an elastic yarn, so that it is possible to meet the demand for a pillow case that fits a pillow having a curved shape.

  An object of the present invention is to provide a bedding cover that solves the above-described problems, specifically, a bedding cover in which at least a part of the material has elasticity.

  The present inventors have intensively studied to achieve the above object, and have completed the present invention.

  That is, the present invention is a cover for bedding, at least a part of which is made of a knitted or woven fabric made of covered yarn, and the covered yarn has a core portion made of elastic or stretchable fiber, and its core. The bedding cover is characterized in that the weight of the elastic or stretchable fibers constituting the portion occupies 1 to 20% of the total weight of the covered yarn.

  This bedding cover may be in any of the following modes (1) to (5) or in a combination of two or more of them.

(1) A covered yarn is formed by coating a core made of polyurethane fiber with a coating material made of one or more fibers selected from the group consisting of cotton, polyester, acrylic, rayon, polypropylene, wool, hemp and nylon. The above-mentioned cover for bedding.

(2) The cover for bedding, wherein the unit weight of the knitted fabric or the fabric made of covered yarn is 100 g / m ^{2 to} 360 g / m ² .

(3) The bedding cover described above, wherein the bedding cover is at least one selected from the group consisting of bed sheets, pillow cases, mattress wrapping, mattress sheets and pillow covers.

(5) The above-mentioned cover for bedding, wherein the knitted fabric or the fabric made of covered yarn is a knitted fabric.

  The present invention provides a bedding cover that can be used for various sizes of bedding.

  In addition, the present invention provides a bedding cover in which the problem of being unusable due to shrinkage in washing is solved.

  Furthermore, the present invention provides a bedding cover that fits a bedding having a curved shape, particularly a pillow.

  The present invention is described in detail below.

  In the present invention, the bedding cover refers to all bedding, that is, those used to cover a futon or a pillow. Specific examples thereof include bed sheets, pillow cases, mattress wrapping, mattress sheets, and pillow covers.

  Covered yarn is formed by covering a core made of elastic or stretchable fiber with a thread or fiber made of a material different from that used for the core.

  Examples of elastic or stretchable fibers constituting the core include polyurethane fibers and polyurethane fibers (mixed fibers of polyurethane and other materials). A typical example is a polyurethane fiber called spandex. The core is, for example, a polyurethane fiber thread.

  The covering material covering the periphery of the core part, specifically, the material of thread or fiber, for example, is not particularly limited as long as it is a different material from that used for the core part. Examples include cotton, polyester, acrylic, rayon, polypropylene, wool, hemp and nylon. These materials may be used alone or in combination of two or more. Note that “mixed use” is a concept including, for example, use as a blended yarn, use as a blended fiber, use of two or more kinds of different materials, and the like. The texture of the covering material covering the periphery of the core is recognized as the texture of the covered yarn.

  Typical examples of the covered yarn include a single covered yarn 10 shown in FIG. 1, a double covered yarn 20 shown in FIG. 2, and a core span yarn 30 shown in FIG.

  The single covered yarn 10 is, for example, a cotton yarn 3 wound around the core portion 1 made of polyurethane fiber, and the double covered yarn 20 is, for example, around the core portion 1 made of polyurethane fiber. The polyester yarn 3 is wound on the outer side, and the cotton yarn 5 is wound on the outer side. In addition, the thread | yarn wound twice around the core part 1 may be the same material.

  The core spun yarn 30 is a spun yarn obtained by putting the polyurethane yarn 1 in the core in a spinning process of, for example, cotton or wool short fibers 7. It is preferable to use a core span yarn for all or part of the bedding cover of the present invention.

  In such a covered yarn, the material of the core portion is an elastic or stretchable fiber, so that a knitted fabric or a fabric manufactured using the covered yarn exhibits elasticity or stretchability.

  The covered yarn used in the present invention has a core portion of 1 to 20%, preferably 2 to 15%, more preferably 4 to 12%, particularly preferably 6 to 10% of the total weight of the covered yarn. With such a ratio, the elasticity and stretchability of the core are exhibited, and the texture of the yarn or fiber covering the core is recognized.

In consideration of the strength and durability of the knitted fabric or woven fabric, the unit weight of the covered yarn knitted fabric or woven fabric constituting at least a part of the cover for bedding of the present invention is 100 g / m ^{2 to} 360 g / m ^2. Is preferably 130 g / m ^{2 to} 300 g / m ² , and particularly preferably 150 g / m ^{2 to} 250 g / m ² .

  At least a part of the cover for bedding of the present invention is made of the knitted or woven fabric made of the covered yarn.

  “At least a part thereof” means a part or all of the bedding cover. For example, in the mattress wrapping shown in FIGS. 4 and 5, a part 41 (FIG. 4) in contact with two of the four sides or a part 43 (FIG. 5) in contact with three sides is a covered yarn fabric. Manufactured and other locations 45 can be made of cotton broad. In addition, in the cylindrical pillow cover shown in FIG. 6, one half (the part constituting the half of the circumference of the cross section) 51 is made of a covered yarn fabric, and the remaining portion 53 is made of cotton / polyester blended yarn. Can be made of woven fabric.

  Alternatively, in the box-type bed sheet 60 shown in FIG. 7A, the upper lid portion 65 is made of quilting, and the other portions (locations corresponding to the side surfaces of the box) 63 are manufactured with a knitted fabric made of covered yarn. be able to. In such a box-type bed sheet 60, the quilted upper lid 65 serves as a bed pad that softens the surface of the bed mattress and enhances the sweat absorption.

  Of course, the entire bedding cover may be made of the covered yarn knitted fabric or woven fabric.
