Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a transfer paper which is capable of transferring various figures or characters to cotton fabric clothing by using disperse dyes.

[0002]

2. Description of the Related Art Transfer papers using disperse dyes are mainly used for chemical fiber fabrics which have a high degree of shrinkage and expansion of the fiber structure due to heat and are excellent in the penetration and absorption of the disperse dyes. When using a transfer paper to transfer to a chemical fiber fabric, the dye of the transfer paper is dispersed inside the fiber in the process of expanding and contracting the fiber structure by heat.
Penetration and clear transfer can be obtained.

However, the property that the chemical fiber woven fabric expands and contracts by heat is accompanied by drawbacks such as poor ventilation and poor texture. When using a transfer paper that uses a disperse dye on a natural fiber cotton fabric, excellent properties such as texture, hygroscopicity, and ventilation are provided.
On the contrary, it becomes a problem.

[0004] A cotton fabric has a very low degree of deformation due to expansion and contraction of a fiber structure due to heat, and it is difficult to transfer using a disperse dye, and it is difficult to obtain a clear state even when transferred. Especially when using a transfer paper that uses a disperse dye, the penetrating power of the dye is weak,
Since the dye is dispersed, it cannot be transferred to the cotton fabric as it is on the transfer paper.

Therefore, conventionally, a transfer method has been performed in which the surface of a cotton fabric is directly coated with a resin layer such as urethane, and the urethane resin layer increases the washing fastness of the disperse dye.

[0006]

As described above, in the transfer using the disperse dye for the cotton fabric of the natural fiber, the resin layer is directly coated on the surface of the cotton fabric corresponding to the transfer site.
Due to the coated resin layer, there is a problem that ventilation is reduced, the texture is deteriorated, and the original characteristics of the cotton fabric are impaired.

For this reason, transfer using disperse dyes is not suitable for cotton fabrics, and chemical fiber fabrics are mainly targeted. However, it is necessary to develop a transfer paper using a disperse dye, which does not impair the characteristics of a cotton fabric which has a characteristic different from that of the chemical fiber fabric.

It is an object of the present invention to develop a transfer paper using a disperse dye that does not impair the characteristics of a natural fiber cotton fabric and realize a clear transfer.

[0009]

In order to solve the above problems, in the present invention, the transfer site of the cotton fabric is first close to the chemical fiber so that the disperse dye is transferred while maintaining the hue and form. A urethane resin layer is provided on the transfer paper so that the disperse dye can change its properties and penetrate into the fiber structure. Further, a meltable release agent layer is placed between the urethane resin layer and the disperse dye layer so that the disperse dye is not dispersed in the urethane resin layer. By forming such a layer on the transfer paper, the disperse dye and the resin layer do not come into direct contact with each other. When heat is applied, the release agent melts and the disperse dye and resin mix,
Penetrated and transferred to cotton fabric.

The transfer paper of the present invention will be described below with reference to the drawings. FIG. 1 is a cutaway perspective view of the transfer paper of the present invention, and FIG. 2 is an enlarged sectional view of the transfer paper of the present invention. The transfer paper of the present invention has a disperse dye printing layer 2 formed on a mount 1, and a meltable transparent organic wax layer 3 is formed on the disperse dye printing layer 2.
The organic wax layer 3 is formed by coating the transparent urethane resin layer 4 mixed with the phosphorescent powder 4 '.

When transferring using the transfer paper of the present invention,
The procedure and transfer state will be described. The urethane resin layer 4, which is the surface layer of the transfer paper of the present invention, is brought into close contact with the surface of the cotton fabric, and heat is applied at a relatively low temperature of about 150 to 180 ° C. for pressure bonding. The organic wax layer on the disperse dye printing layer 2 printed on the mount 1 is rapidly melted. The heat-treated disperse dye printing layer radiates with the molten wax layer,
At the same time as the urethane resin layer coated on the surface, it melts and mixes with the disperse dye, and penetrates into the fiber structure of the cotton fabric. In this way, it is possible to perform the transfer as it is on the transfer paper.

In the transfer paper of the present invention, the urethane resin layer is melted and penetrates into the cotton fabric to enhance the properties of the cotton fabric to expand and contract like chemical fibers. Due to the expansion and contraction action of the urethane resin, the penetration of the disperse dye is improved, and the printed matter can be transferred as it is on the transfer paper. The organic wax layer between the disperse dye printing layer and the urethane resin layer prevents bleeding of the dye that occurs when the urethane resin layer is in direct contact with the disperse dye printing layer, and melts quickly when heat is applied to the transfer paper. Then, the disperse dye and the urethane resin layer are mixed.

[0013]

According to the transfer paper of the present invention, since the urethane resin mixed with the disperse dye permeates and is transferred into the cotton fiber structure, the original structure state is maintained. Since the ventilation of the fibers is not blocked, the characteristics and texture of the cotton fabric such as ventilation and hygroscopicity can be maintained. Since the image can be transferred as it is on the transfer paper, the hue becomes clearer.
The phosphorescent powder mixed with the urethane resin also has the effect of diverging light in the dark and enhancing the transferred state.
