Abstract

PROBLEM TO BE SOLVED: To provide a system for producing a single full color pattern flocked emblem in low cost by using an ink jet printer. SOLUTION: Ink containing a sublimable dyeing agent is ejected to the pile- flocked surface of a flocked sheet, which is constituted by laminating a thermal adhesive resin layer 2 in which polyester fiber piles are implanted is laminated on a release sheet 1, corresponding to a pattern by using an ink jet printer and the pile-flocked surface is heated to be subjected to sublimation dyeing. This dyed flocked sheet is cut into a desired shape by a cutting plotter and the flocked resin layer is peeled from the release sheet and the surface thereof is brought into contact with an objective material to be bonded thereto under heating and pressure.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to flocking. More specifically, the present invention relates to a transfer flocking sheet capable of providing a full-color pattern.

[0002]

2. Description of the Related Art Originally, flocking is called a pile by an electrostatic flocking machine before a resin is solidified by screen printing in accordance with a pattern of an object material, and then before the resin is solidified. The dyed fiber cut to about 1 mm is skipped and pierced into the resin-pulled portion to be fixed.

As a subsequent improvement, there is a transfer type flocking sheet system. This is done by applying a resin with weak adhesion to the entire surface of the base sheet and then providing a flocking sheet with a uniform pile of flocking from the flocking manufacturer, so the flocking processor purchases a flocking sheet of the required color In this method, it is only necessary to apply a heat-adhesive resin having strong adhesiveness to the pile surface by screen printing in accordance with a pattern.
After that, simply pile the thermo-adhesive resin surface of the flocking sheet on the target material and thermocompress it, and the pile pierced by the weakly adhesive resin is pulled out by the thermo-adhesive resin with stronger adhesiveness and the pile The heat-adhesive resin is simultaneously heat-bonded to the target material while holding the substrate. As a result, a flocked patch of a single color pattern is formed on the target material.

Another improvement is a transfer type,
In addition, there is a sublimation dyeing flocking sheet system that supports full-color patterns. This means that the flocked sheet method is to print a full-color pattern on the base sheet in advance using an ink containing a sublimable dye, and to limit the pile material to white polyester. It differs from using fibers. By heating the flocking sheet, for which pattern printing and flocking work has been completed by this method, at about 200 ° C. for about 1 minute, the sublimable dye is diffused into the resin, and the polyester pile group piercing it is removed.
Dyes faithfully on printed patterns. Subsequent steps are exactly the same as those of the flocking sheet method, whereby it is possible to form a flocking patch of a full-color pattern on the target material.

[0005]

The above prior arts are all
Since it requires screen printing for resin coating according to the pattern, it can only handle large lots. In the case of a full-color pattern, four-plate printing with ink containing the sublimable dye is required, so that the burden is even greater.

[0006]

Means for Solving the Problems As a result of diligent studies, the present inventor has found that, on a release sheet, a heat-adhesive resin layer in which a pile of polyester fibers is implanted is laminated, on the pile-implanted surface of the flocking sheet. By jetting ink containing a sublimable dye using an inkjet printer, the ink is received on the pile flocked surface without bleeding,
By heating this surface, the pile is dyed in a deep color up to the root portion, and by cutting this flocking sheet with a cutting plotter, the flocking resin layer cut into a desired shape can be easily taken out. By thermocompression bonding in the way that the surface contacts the target material,
The inventors have found that a full-color flocked patch can be formed on a target material, and have reached the present invention.

[0007]

In general, a receiver that receives ink droplets from an ink-jet printer is made of a resin that absorbs ink on the substrate surface and swells so that the ink does not bleed and dries rapidly.
It has a structure in which a resin containing a large amount of porous silica or the like is applied. The technique of directly spraying a dye ink onto a fabric to dye it has also been generalized, but in this case, it is essential to provide a coating layer on the fabric surface in order to prevent bleeding. However, even with the same fiber material, the surface of the flocking sheet of the present invention has a structure in which upright piles having a length of 1 mm or less are densely packed, and ink droplets adhering to the pile tip or the middle of the pile straddle the pile. There is no horizontal bleeding. For this reason, even if it is not dried, it does not bleed even if it is left in a liquid state while being attached to the pile, so that the pile surface is heated without contact or light contact after an arbitrary time,
The pile surface can be dyed very finely.

The heat-adhesive resin layer laminated on the release sheet of the flocking sheet of the present invention does not necessarily have to be a single layer. First, a two-layer configuration in which a heat-adhesive resin layer is laminated and a pile-implanted resin layer on which piles are implanted has different functions of thermal adhesion and pile graspability.
This is convenient because it can be performed with different resin designs. As the heat-adhesive resin, a thermoplastic resin having heat-adhesion in a range of about 100 to 160 ° C. may be appropriately selected. For example, polyvinyl acetate copolymer, polyvinyl alcohol, polyvinyl formal, polyvinyl butyral, acrylic adhesive, ethylene-vinyl acetate copolymer, ethylene-vinyl alcohol copolymer, ethylene-ethyl acrylate copolymer, ethylene-acryl Examples include acid copolymers, vinyl chloride-vinyl acetate copolymers, vinyl chloride-vinyl acetate-maleic anhydride copolymers, polyvinyl ethers, polyester resins (saturated amorphous polyesters), and cellulose derivatives.

As the resin layer for flocking, an acrylic resin used in a conventional method may be used as it is. However, the flocked sheet is formed by flocking a white polyester pile on the entire surface. However, in view of the length and density of the pile, there is no shielding property that only blocks the color of the target material after thermocompression bonding. For this reason, it is necessary to improve the white shielding property by blending a white pigment such as titanium oxide into the resin layer for flocking. In some cases, a white pigment may be blended in the heat-adhesive resin layer. The heat-adhesive resin layer and the flocking resin layer may be laminated so as to have a total thickness of about 50 to 200 microns.

[0010]

EXAMPLE A polyester-based thermo-adhesive resin was first laminated on a release paper having a thickness of 120 microns to a thickness of 50 microns. Next, an acrylic flocking resin containing titanium oxide was laminated to a thickness of 30 microns. Thereafter, a white polyester pile having a length of 0.5 mm was implanted using an electrostatic flocking machine to obtain a flocking sheet of the present invention.

[0011]

According to the present invention, it is possible to produce a flocking patch of a full-color pattern individually using an ink jet printer at low cost.
