Description

The present invention relates to a cover using a grass stalk fabric laminate.

  Grass stalk fabrics made by weaving grass stalks with warp threads have long been used for various purposes as a natural material.

  For example, igusa is a plant belonging to the department of licorice family, and is used as a tatami mat, overlay, cocoon, and flower bud by making it into a woven fabric. It is used by being molded into miscellaneous goods such as book covers.

  In addition, rice bran is a dried product of the stems of gramineous plants typified by rice and wheat, and is used as a tatami floor and rice cake (rather) by making it into textiles. Has been.

  When these grass stalk fabrics are used for miscellaneous goods, they are often used or processed by being folded or rolled parallel to the longitudinal direction of the stem part, but there are not many items described in the literature. They are sold exclusively through mail order.

  Moreover, although it is known that a tatami surface is made into a laminated body (patent documents 1 and 2), most are used indoors as a tatami mat, and the core material etc. are essential, and the document used as a material of miscellaneous goods It doesn't hit.

In Patent Document 1, the front surface, end surface, and back surface of a square core plate are covered with a surface sheet such as a tatami mat, and the back sheet is attached to the back surface, and is used indoors as a tatami mat.
Patent Document 2 is one in which two tatami mats in which two long and narrow rectangular tatami mats are stacked are woven together in a lattice pattern, and is also used indoors as a tatami mat.

  When using tatami mats, cocoons, flower buds, cocoons, etc. as materials for miscellaneous goods, it is necessary to cut them to a certain size, but on the cut surface parallel to the stems of the grass stems (hereinafter referred to as side surfaces) The problem of so-called fraying occurs that the grass stalk is detached from the warp by cutting, and the cut surface parallel to the thickness direction of the grass stalk (hereinafter referred to as the cross section) exposes the cross section of the grass stalk. There is a problem of rushing.

  In order to solve these problems, even when using grass stalk fabric as miscellaneous goods, the side and cross-section of the grass stalk fabric (hereinafter collectively referred to as the end surface), such as the edges of tatami mats, overlays and straws. The peripheral parts of the front and back are sewn so as to cover the front and back of the grass stalk fabric with a certain width with a cloth (hereinafter referred to as an edge cloth).

  In addition to the rim fabric, either the front or back of the grass stalk fabric can be easily damaged even if a rim fabric is attached. It will be covered with.

  At this time, as shown in FIG. 3 (2), since the lining cloth and the edge cloth are sewn together, the thickness of the edge portion is increased, and the cross-section of the grass stalk fabric is linear with the edge cloth and the lining cloth. It will be fixed to.

As a result, when the grass stalk fabric is bent or rolled in parallel with the longitudinal direction of the stem part, resistance by the rim cloth (hereinafter referred to as bending resistance) occurs, and the user feels this as elasticity. However, because the thickness of the front and back edge fabric parts is large, the bending resistance increases, and when used for miscellaneous goods with opening and closing, for example, book covers, the book opens and the followability of the cover is bad Problems arise.
In addition to the book cover, if the bending resistance is large, the moldability is deteriorated, and there is a problem that it takes time and effort when manufacturing the sundries.

  In addition to the above, the inventors of the present invention have a bending force that is too strong by differently attaching the edge cloth and the backing cloth, that is, by sewing the edge cloth and bonding the backing cloth to the edge cloth with an adhesive. The present invention has been completed by finding that the resistance is appropriate as miscellaneous goods.

  The object of the present invention is to solve the above-mentioned problems, and to take advantage of the Japanese-style taste of grass stalk fabrics, the functions of moisture absorption and dehumidification, and the good sensation, while being light, moderate elasticity and good tracking It is intended to provide material.
