Description

LASER TEXTILE PROCESSING MACHINE
Technical Field
The present invention relates to a laser textile processing machine which is used for all types of textile products, primarily denim, which brands point or line based images on textile products by means of the laser technology it comprises, and which allow textile products to possess a more natural worn out look without having to be repaired after the wearing out process carried out by means of a laser beam.
State of the Art
The "denim" fabric woven consists of two layers. In newly produced textile products, the top layer of the fabric is worn manually by using rotary sanders to give it a worn out look. Alternatively, this process is carried out by directing a laser beam to the desired area on the fabric. After the top layer has been eroded by a laser beam or manual labor, the threads in the bottom layer of the fabric become exposed.
When it is desired to perform this process using a laser beam, the scanner head directs the laser beam to the fabric surface row by row. The intensity of the laser light is adjusted according to the properties of the fabric or the washing steps of the product.
The burning image, which is drawn point or line based, is examined by a design program and prepared to be burned in rows with a laser beam. The rows or lines obtained from the examination are sent to the scanner head so that these rows or lines are burnt by laser beam.
The laser beam, which is round, travels in a linear direction while each laser beam overlap with another. Therefore, the head and end of the line are exposed to laser beam for less time than the middle part of the line.
In order to fill the interior of the burning image in rows (lines), it is necessary to place the next line by moving away a certain distance from the previous line. In this way, the burning image is transferred onto the fabric in lines until the image is completed.
Lines or rows are placed by shifting a certain distance so that they overlap. As a natural result of this process, the first and last line are exposed to less laser beam than the inner parts of the drawing.
The perimeter of the pattern is scanned with fewer laser beams. Since the laser beam acts on the perimeter of the bunt image less, the desired natural worn out look cannot be achieved. The upper layer of the fabric around the pattern is not worn enough, which causes white areas to form around the drawing after burning.
In order to resolve this error, establishments are trying to repair the products again by manual labor. Most of the time, due to this error, this process cannot be done by laser, and it is done entirely by manual labor. A large amount of dust is formed as a result of the manual labor process, which seriously threatens the health of the workers. In addition, the required standard quality is not established in the products.
The problem occurs in the form of a whiteness around the drawing in the worn image that has been washed after laser printing. White threads are not fully opened up to the colored places in the color of the fabric.
In the patent application document no. WO2018127838 in the literature, burning is performed on fabrics using laser beam. The process carried out in the relevant document has differences with the invention of this description in terms of content and method.
As a result, due to the negativity described above and the inadequacy of the existing solutions on the subject, an improvement in the relevant technical area has been made necessary.
Object of the Invention
The invention is inspired by existing situations and aims to solve the above-mentioned disadvantages.
The purpose of this invention, based on the laser technology, is to provide branding point or line based images on textile products.
Another purpose of this invention is to ensure that textile products have a more natural worn out appearance without having to be repaired again as a result of the wear processes performed using a laser beam.
The structural and characteristic features and all advantages of the invention will be understood more clearly through the detailed explanation written with the following figure and references to this figure, and therefore assessment should be made by considering this figure and detailed explanation.

Digitally prepared burning images are required for performing wearing operation with laser technology on textile products (A) such as denim and such fabrics. These pictures are prepared to be sent to the control unit (5) by means of the computer (6).
The computer (6) adjusts the placement of the burning image in the burning area on the textile product (A) and the laser generator's (2) power is adjusted to the desired value using various parameters.
The computer (6) sends the collected and prepared data to the control unit (5). The control unit (5) examines this data and commences operations.
After placing the textile product (A), which is to be worn by laser beam, is placed under the scanner head (4), the processes begin. The laser beam is produced by means of the laser generator (2) and this beam is directed over the textile product (A) to be burned with the help of the optical setup (3) and the scanner head (4).
The computer (6) sends the burning image to the scanner head (4) in rows for the orientation of the laser beam. These lines can be at any angle relative to the burning area. The burning image is burnt on the textile product (A) row by row.
Firstly, the computer (6) finds the perimeter points of the burning image so that the burning image is burned by laser beam on the textile product (A). The computer (6) point by point scans the burning image in rows and columns. If the scanned point is black and there is a white spot around it, the computer (6) determines this point as the perimeter point.
The computer (6),
❖ shifts the perimeter point 1 to 10 mm to right if the left side of the perimeter point is white,
❖ shifts the perimeter point 1 to 10 mm to down if the upper side of the perimeter point is white,
❖ shifts the perimeter point 1 to 10 mm to left if the right side of the perimeter point is white,
❖ shifts the perimeter point 1 to 10 mm to up if the lower side of the perimeter point is white
The computer (6) determines the target interval distance between the perimeter points according to the structure and characteristics of the textile product (A). The target interval distance can be between 2 and 30 millimeters.
The resulting perimeter points are re-examined by the computer (6) from the first point to the last point.
The computer (6) assigns the first point as the reference point A. The computer (6) finds the distance between two points by finding the distance from the reference point A to the next point with the help of the following formula.
Figure imgf000007_0001
(formula , )
If the distance found is shorter than the target interval distance, the computer (6) removes this point from the perimeter points. If the distance found is equal to or greater than the distance of the target interval, the computer (6) reassigns this point as a reference point. The computer (6) continues to examine perimeter points until all perimeter points are covered using this algorithm.
The computer (6) uses this algorithm to ensure that the distances between the perimeter points are not shorter than the distance of the specified target interval.
The scanner head (4) uses information determined by the operator using the computer (6), the maximum exposure time for the point to be exposed to the laser beam, and the maximum exposure time for the point to be repeated several times in a row. Using this information, the scanner head (4) burns the perimeter points with the laser beam.
The computer (6) is able to perform linear operations for the specified points, in addition to pointwise application. Linear operation can be in geometric shapes such as circles, ellipses, squares or rectangles or similar at determined points.
If it is desired by the operator to treat the points linearly, the information related to the branding speed that the scanner head (4) follows on the textile product and the number of times that the linear drawing will be repeated is received by the computer (6) from the operator. The computer (6) operates based on this information.
