Description

Method and Apparatus for Planting Flock on Textile Paper {Method and appararus for adhesion a flock on a textile}

The present invention relates to a method and apparatus for seeding flock on textile paper, and more particularly, to stably flock the floc in a predetermined pattern on the surface of the textile paper and to reuse the remaining floc. The present invention relates to a method and apparatus for planting flocs on fabric paper which are material-saving and advantageous for improving the working environment.

In general, transfer paper is generally used as a method of planting flock on the surface of the textile paper.

The method of planting the floc from the transfer paper to the fabric paper firstly attaches the peelable adhesive 2 to the desired shape in order to plant the functional powder onto the paper 1 as shown in Fig. 1A, and shown in Fig. 1B. As shown in FIG. 1C, the flock 3 made of short fibers containing functional powder is stacked on the entire surface of the sheet 1 to which the adhesive 2 is attached as shown in FIG. A floc 3 is attached and a thermal adhesive 4 acting by heating is attached on the floc 3 as shown in FIG. 1D, and then thermally pressurized as shown in FIG. The thermal adhesive 4 is heated and pressed to attach, and then the ground 1 is removed.

However, when the floc 3 is attached to the surface of the textile paper 5 in the above manner, there are the following problems.

First, the process is cumbersome by including a process of adhering two kinds of adhesives (2) (4).

Secondly, the process of removing the floc 3 which is not attached to the adhesive 2 by a brush and a suction method is added separately, so productivity is bad.

Third, by transferring and attaching the floc to the surface of the fabric paper using the transfer paper to which the floe is separately attached, the process is complicated and a separate transfer paper is required, thereby reducing productivity. In addition, it is disadvantageous for material saving, such as waste of the remaining transfer paper by shearing and using the transfer paper in a required pattern.

The present invention has been made to solve the above problems, and an object of the present invention is to provide a method and apparatus for attaching an improved floc to textile paper so that the flocs can be directly planted on the surface of the textile paper.

It is another object of the present invention to provide a method and apparatus for planting flocs onto fabric paper which can prevent the environmental pollution from dropped flocs generated during the process of planting flocs on the surface of fabric paper.

It is still another object of the present invention to provide a method and apparatus for planting flocs onto fabric paper to recover flocs that have not been planted on fabric paper and to reuse them.
