How Does Industrial Embroidery Work?
However, how does such an embroidery design get onto caps, pullovers or pockets?
At the beginning stands the idea of a design, mostly in the form of a company logo together with a slogan. If the idea only exists on paper, the design must be digitized into computer readable data. This takes place e.g. by reading in with a scanner. Then if the concept is obtainable as a file, it must be converted into vector graphics. In this case, individual pixels are no more calculating for the design but the lines, which separate a color field. One recognizes vector graphics also by the fact that one is able to enlarge them infinitely without quality loss, because the dividing lines always keep sharp.
These vector graphics are loaded into the punch program. The semantics of the information is to be traced back to the procedures before the computerized embroidery program creation where the commands were nevertheless pricked by hand in a punch card made of hard paper.
The puncher on the software decisively determines the quality of the finished stitch content. Here there are dozens of parameters such as stitch density, stitch direction, stitch distance, stitch pattern and the precedence of stitch work correctly on the concept, the embroidery machine and the textiles to be embroidered. consequently a cap requires a different embroidery program than a leather jacket, already if it concerns one and the same embroidery concept.
Not without reason there are companies which have specialized one and only in the production of the embroidery motifs.
Then if the embroidery program is ready, it is transmitted either by network, direct connection or floppy disk to the embroidery machine.
Again also in the embroidery machine there are different parameters which can enhance the embroidery consequence or make it worse. The most important ones here are above and under thread tension and embroidery speed.
Then the real conversion of the program into the textile embroidery is only routine. The embroidery machine is made, in rule, just like a normal house sewing machine, many elements, e.g. the under thread guidance looks very similar.
The basic difference is the amount of needles, which reaches from 6 up to 18 automatically changing needles and consequently usable colors in one concept.
Then when the concept is constructed, a quick change of the embroidery piece can be done, which makes the embroidery very interesting especially for bigger works orders. Bigger embroidery machines are so-called multi head machines, here i.e. up to 24 embroideries are done at the same time. This increases the economic efficiency and consequently makes the price per piece more attractive.
With the use of the finished product there are hardly any restrictions. consequently, work clothes are embroidered with pleasure. Also clothes that needs chlorine laundry, like for example doctor’s smocks can be permanently improved with special sewing cotton.
