Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a flocked printing material capable of obtaining a clear pattern and a method for producing the same.

[0002]

2. Description of the Related Art Conventionally, clothes, curtains, shoes, bags, etc. have been added in order to increase the added value such as three-dimensional feeling and touch, and to improve the commercialability.
A direct flocking method is known in which flocking is applied to various base layers such as floor mats.

Further, in the flocking process of coloring monochromatic or multicolored, after the pre-dyed flocking in which short fibers are first dyed and then flocked, short fibers are flocked to the base layer to form a flocked fabric having a flocked layer. Post-dying and flocking of a flocked layer to be dyed is known.

It is known that the dyeing method is mainly used for the pre-dyed flocking, and the various dyeing methods such as the dye printing and the pigment printing are used for the post-dyed flocking.

[Problems to be Solved by the Invention] By the way, in recent years, with the diversification and upsizing of user's taste, better variety of visual, tactile, texture, design, etc., small quantity production, variable area machining, precision machining There is a strong demand for easy multicolor processing.

[0006] In general, however, the pre-dyed flock is suitable for single-color flocking, and the post-dyed flock is suitable for multi-color flocking. However, when short fiber is dyed first to perform multi-color flocking and after-dyed flocking. When performing multicolor flocking processing with both, it is necessary to prepare special equipment to make both of them multicolored, and to remove excess dyes and pigments attached to the short fibers with the flocked layer. However, there is a drawback in that a laborious processing means must be adopted, and a multicolored flocked printing fabric according to a user's request cannot be easily provided.

The present invention solves the above problems, and uses a commercially available general-purpose inkjet printing machine that works in conjunction with a personal computer to perform a wide variety of products, small to large volume production, variable area machining, multicolor machining, and fine machining. It is an object of the present invention to obtain a flocked printing material which is easy and has a better visual feeling, touch feeling, and texture design property corresponding to the diversification of user's taste and higher quality, and a manufacturing method thereof.

EXAMPLE An example of the present invention will be described with reference to FIGS. 1 to 14. Fiber material 1 is a rayon filament bundle and a dye fixing layer 3.
Acrylic emulsion and silicaloid with a crystallization temperature of 40 ° C. are used as the material, a rayon non-woven fabric is used as the base layer 5, an acrylic emulsion is used as the material of the adhesive layer 6, and a bubble jet printer, which is one of thermal inkjet printers for the inkjet printer 11, is available as BJ -COLOR PRINTER BJC-600J
(Manufactured by Canon Inc.), dedicated 4 color independent inks were prepared for inkjet ink.

First, an acrylic emulsion having a crystallization temperature of 40 ° C. and silicaloid are prepared as a dilute aqueous solution, and the fiber material 1 which is a long fiber bundle of rayon is immersed in the acrylic emulsion and the silicaloid are adhered and taken out. Then, the silica was dried to fix the silica to the fiber material 1 which is a rayon long fiber bundle with acrylic, and this was cut to form short fibers 4 having the dye fixing layer 3.

Next, a rayon nonwoven fabric is used as a base layer 5 and coated with an acrylic emulsion to form an adhesive layer 6,
An adhesive layer formed by electrostatically flocking short fibers 4 having a dye fixing layer 3 previously formed on an adhesive layer 6 using an electrostatic flocking device called a flocking machine to form a flocked layer 7 and coating an acrylic emulsion. 6 was formed and dried to form a flocked dough 8.

Next, the formed flocking material 8 is cut into A4 size printable by the inkjet printing machine 11, and the photo original stored in the personal computer 9 is printed by the inkjet printing machine 11 on the flocking layer 7 of the flocking material 8. Printed pattern 12 was formed by outputting a photographic pattern by separating the four colors by discharging the dedicated ink.

Next, heat treatment is performed to firmly fix the base layer 5 which is a rayon nonwoven fabric and the short fibers 4 by the adhesive layer 6 which is an acrylic emulsion, and the dye in the ink of the ink jet ink is formed as a mixed layer of silk and acrylic. It firmly adhered to the dye fixing layer 3 thus formed to form a flock printing textile 20.

Next, the flocked printing cloth 20 is cut to form a flocked printing cloth piece 17, and the flocked printing cloth piece 17 is sewn to the sewing section 1.
