Description

  The present invention relates to a solid delineation material for washable fabrics that can be used in applications such as dressmaking or embroidery.

  In the field of dressmaking and embroidery, means for drawing a sewing pattern or line on a cloth in advance before cutting, sewing or embroidering the cloth is widely used. In this means, a so-called solid drawing material called chaco, copy paper called chaco paper, or a marking pen called chaco marker is used. These materials are required to have a capability of clearly observing the depiction at the time of cutting, sewing or embroidering the fabric, and easily erasing the depiction after cutting, sewing or embroidery. .

  Chaco or chaco paper has been widely used conventionally. For example, Japanese Patent Laid-Open No. 49-96841 (Patent Document 1) discloses choking paper. However, such a choking paper requires a considerably strong pressing force when the drawing portion is written on the fabric. Therefore, it is not easy to mark the depiction part on the fabric. In addition, it is difficult to completely drop the depiction portion described in this way by washing with water. In this case, there is also a problem that the fabric and the embroidery may be damaged if the drawing portion is thoroughly washed until it is completely dropped.

  Marking pens called chaco markers are a tool whose use is expanding in recent years. Such a chaco marker is described in, for example, Japanese Patent Laid-Open No. 10-220675 (Patent Document 2) or Japanese Patent Laid-Open No. 2000-26783 (Patent Document 3). The depiction portion described by these chaco markers is opaque and visible at room temperature, but has the property that the depiction portion becomes transparent by heating the depiction portion using an iron or the like. However, these chaco markers tend to be inferior in visibility as compared with the depiction portion described by the chaco or the chaco paper. In particular, there is a problem that visibility is inferior when a white or light-colored drawing portion is written on a dark fabric.

The solid delineation material for a washable fabric of the present invention contains a colorant (A). In the present specification, the “colorant (A)” means a component capable of visually recognizing a drawing portion when the drawing portion is written on the fabric using a solid drawing material for a washable fabric. As this coloring material (A), a coloring material having a chromatic color or an achromatic color can be mentioned. Various pigments and dyes can be used as the colorant (A). Specific examples of pigments include organic pigments such as azo pigments, nitroso pigments, nitro pigments, basic dye pigments, acid dye pigments, built dye dye pigments, mordant dye pigments, and natural dye pigments. Inorganic pigments such as ocher, barium yellow, ultramarine, bitumen, cadmium red, barium sulfate, titanium oxide, dial, iron black and carbon black. Specific examples of the dye include acid dyes, direct dyes, basic dyes and the like. These colorants (A) may be used alone or in combination of two or more. Two or more kinds of colorants (A) may be mixed and adjusted to a desired hue.

As a preferred coloring material (A),

  In the solid drawing material for water-washable fabric of the present invention, the total content of the coloring material (A) composed of these inorganic pigments, organic pigments and / or dyes is based on 100 parts by weight of the solid drawing material for water-washable fabric. It is preferable that it is 10-35 mass parts. When content of a coloring material (A) is the said range, there exists an advantage that the favorable visibility and water-washing removability of a description part can be ensured.

Polyethylene oxide adduct of long chain aliphatic alcohol (B)
The solid delineation material for water-washable fabrics of the present invention contains a polyethylene oxide adduct (B) of a long-chain aliphatic alcohol. By including the polyethylene oxide adduct (B) of a long-chain aliphatic alcohol in the solid delineating material for water-washable fabrics of the present invention, it becomes possible to erase the described descriptive part very easily by washing with water.

  In the case of chaco or chaco paper, a softness is required in order to easily attach the depiction part to the fabric. On the other hand, the hardness is also required to prevent the coloring from appearing in a place other than the place where the depiction portion is attached and staining the fabric. Further, after slicing, sewing or embroidery, water erasability that can easily erase the depiction portion by water rinsing means is also required.

  In conventional chaco, a wax component such as a plant wax is generally used in order to develop the above-mentioned softness, hardness, and water washability. By using such a wax component, good softness is expressed, and it becomes possible to easily attach a drawing portion to the fabric. However, since the wax component is generally highly lipophilic, there has been a problem that the water erasability is poor.

  In the case of using a wax component in chaco, the washing erasability can be improved by using a certain amount or more of a surfactant. However, when a certain amount or more of the surfactant is used in order to improve the washing erasability, there is a problem that the fabric is contaminated by coloring in a place other than the place where the drawing portion is attached.

  In this invention, it became possible to solve the said problem by using the polyethylene oxide adduct (B) of a long-chain aliphatic alcohol in the solid depiction material for washable cloths. The solid descriptive material for water-washable fabrics of the present invention does not contain vegetable wax generally used in conventional chaco or contains only a very small amount compared to the conventional content. In the present invention, by using a specific compound called a polyethylene oxide adduct (B) of a long-chain aliphatic alcohol in place of the vegetable wax, extremely high water erasability is ensured while preventing contamination of the fabric. It was to be done.
