Abstract

This invention is a method of creating a pattern by spraying a chemical over a base material to stick the flocks, used in artificial suede production, upholstery, clothing, automotive etc.

SPECIFICATION

TECHNIQUE FOR STICKING FLOCK PATTERNS ON FLOCKS

TECHNICAL FIELD

KNOWN STATUS OF THE TECHNIQUE

Currently, the flock sticking on flock method is performed by flocking the whole surface and then treating the flocked surface with adhesives to create patterns totally or by using rotary press or similar means, finally re-flocking the surface once more. This method requires that in order to increase the offered product variety, different templates have to be made for each different pattern design. Preparation of each template costs money and time and moreover, the template method is not fit for production of patterns with fine designs.

The most widely used method in our times is a patented method where the adhesive is applied on artificial suede to create patterns by using a rotary press or other similar printing means. The drawback of this method is the costs and loss of time involved for producing the different templates required for each pattern design. Moreover, the template method is not fit for production of fine pattern designs.

DESCRIPTION OF THE INVENTION

The invention comprises of a computer controlled method for creating patterns, which can overcome the drawbacks mentioned above, not by rotary press or similar means, but by spraying a chemical for providing sticking the flocks on artificial suede. The desired pattern is prepared on the computer and the computer controlled system applies the chemical for sticking the flocks on the textile or artificial suede, by opening and closing the spraying nozzle holes, to create the pattern design. Thus, problems rooted in the costs involved and time lost in preparing different templates for each pattern design, time lost in cleaning of the different templates, inability to print fine pattern details, are all being removed. The desired flocked pattern design thus becomes applicable only upon creation of that particular pattern design on the computer.

This invention is used in the fields of artificial suede production, upholstery, clothing, automotive etc.

Through the use of flock sticking method, the textiles become entitled to features such as pleasant appearance, flexibility, protection against scratches. This method is preferred as it is less costly, saves time and is capable of creating more sensitive pattern designs. The supremacy of the invention lies in the fact that money and time is saved without having to create different templates for each pattern design. Moreover, all types of pattern designs allowing for the minute details are possible to create and to apply. Besides, when flocks are being applied by using the spraying system, it is also possible to use adhesives with different colors which in turn help create striking appearances and feelings of depth.

The essential motive of the invention is, when applying the flock on top of flock process, to apply pattern designs by using only the templates to create the design instead of coating all of the flocks. The most important differentiating factor of the invention is the utilization of computer controlled chemical spraying system for sticking the flocks instead of the rotary pressing or similar techniques used by the contemporary methods. The working principle of this system is preparation of a pattern design on the computer. Then the pattern design heads, in the machine which is made up of a matrix of nozzle holes, spray the chemical which helps sticking of flocks on the textile, by opening and closing the spray nozzles according to a defined pattern and sequence. The chemical bubble intended to stick the heated and then cast flocks, sticks onto the textile directly. Thus it is intended to create a patterned flock, as after the flocks are cast they shall only stick on the chemical which shall provide the sticking of flocks only according to the intended design configuration. Without the need for preparing a template, as it is the case with the existing methods, lower manufacturing costs can be attained by faster production, without requirement for templates and by being capable of creating more refined pattern designs.

EXPLANATION AND APPLICATION OF THE INVENTION

The invention comprises of textile or artificial suede on which flocks shall be applied (1), the computer controlled chemical spraying system providing for sticking of flocks (2), flock casting unit (3), collecting unit (4), drying unit (5), artificial suede (6), flock (7), adhesive (8) and textile material (9).

Artificial suede or textile (1) are the materials on which flocks shall be applied. The computer controlled chemical spraying system (2) which shall provide for sticking of flocks is a computer controlled system designed to spray the chemical on the textile (9) in order to provide for sticking of flocks into the desired pattern design. The flock casting unit (3) is the unit which provides spraying of the chemical with the desired colors and features, which shall stick (8) the flocks intended for application on the textile. The collecting unit (4) is the unit which collects the excessive flocks (7) and feed them into the flock casting unit (3). Drying unit (5) is the unit which provides for drying of the chemical which provides sticking (8) of flocks and their fixing on the textile, and the cast flocks on which it is sprayed. The textile which is printed with the desired pattern designs is the artificial suede (6).

The textile or the artificial suede (1) material which has been pre treated with flock application is placed where the application shall be made. The adhesive (8) is sprayed onto the textile in the desired design pattern by using the computer controlled chemical spraying system (2) providing sticking of flocks. Flock casting unit (3) casts the flocks with the desired colors and features (short monofilaments such as natural or synthetic cotton, rayon, nylon, polyester etc.) onto the textile. Collecting unit (4) collects the excessive flocks (7) on the textile and feeds the excess flocks to the casting unit (3). The adhesive (8) and the flocks (7) on the textile which is pushed through the drying system (5) are dried and fixed to the textile.

The chemical spraying system (2) providing sticking of flocks is connected to the computer and controlled by the computer. The spraying nozzles, making up the chemical spraying system (2) providing sticking of flocks (7), are operated for opening and closing by the impulses received from the computer.
