[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dyeing method and a dyeing apparatus for raised fiber products such as fleece.

[0002]

2. Description of the Related Art In recent years, a light, warm and inexpensive fleece (polyester raised knit) material has been widely used as a material for textile products such as outdoor wear and casual wear. The surface of brushed fiber materials such as fleece materials is brushed, and dyeing by simple screen printing method or transfer label method does not allow dyes or pigments to enter the fabric, and the dyes or pigments are fixed. Therefore, it was not possible to provide the dyeing fastness that can be practically used.

Further, as a method for dyeing a textile material, a paste obtained by mixing a discharge printing agent and a dye is printed on a plain dyed cloth,
2. Description of the Related Art Color discharge printing is known, in which steaming heat is applied to bleach a previously dyed color and a printed dye is colored. When the raised fiber material is dyed by this color discharge, the fixing degree of the dye or pigment is improved as compared with the above-mentioned dyeing method, and thus it has been used as a dyeing method for the raised fiber material.

For example, as shown in FIG. 4, when dyeing a dyeing section 30e of a garment 30 made of a fleece material,
Each of the constituent materials was sewn and dyed on the finished garment 30. That is, the sizing agent 30 in which the discharge agent and the dye are mixed is added to the dyeing section 30e which is a part of the wear 30.
Is printed, and a heater is pressed against the dyeing part 30e on which the sizing agent 40 has been printed and the area 20 around the dyeing part 30e to heat and press the bleaching of the cloth in the dyeing part 30e, and the dye contained in the sizing agent 40 It was colored.

[0005]

However, the dyeing of the fleece material by the above-described color discharge printing involves heating and pressurizing a partial range 20 of the finished wear 30 with a heater. There was a problem that the texture of the dough changed between the heated and pressurized part and the other part, such as the part that was heated shrinks into a felt compared to other parts and the thickness of the dough becomes thin. . In addition, a boundary is formed between the heated / pressurized portion and another portion, and the heated / pressurized portion is faded, resulting in color unevenness with the other portion.

[0006] Therefore, in order to reduce the change in texture and color unevenness due to heating and pressurization, the heating temperature and pressure are set low. However, when the heating temperature and pressure are low, the dye There was a problem that the coloring quality of 40 was poor and the dyeing quality was poor, such as blurring of the edge portion of the pattern of the dyed portion and dull coloring.

[0007]

The problem to be solved by the present invention is as described above, and the means for solving this problem will be described below.

That is, according to the first aspect of the present invention, a coloring dye is printed on a portion to be dyed of a constituent material of a raised fiber product using a raised fiber material, and then the constituent material is sewn to produce a raised fiber product. First, heat and pressure are uniformly applied to all the constituent materials constituting the napped fiber product to carry out color discharge printing.

In the second aspect, the heat and pressure are applied from the side surface of the dyeing target portion in each constituent member.

According to a third aspect of the present invention, there is provided a heater and a work table arranged so as to face the heater, and a raised fiber product using a raised fiber material is formed on a mounting surface of the work table. All the constituent materials before sewing can be placed,
The heater can be pressed against almost the entire area of the mounting surface.

In the present invention, the work table is arranged below the heater and is vertically movable.

In the present invention, the heating temperature of the constituent material placed on the work table by the heater is 200 ° C. or higher.
