Sewing Machine embroidery

Machine embroidery

Machine embroidery is an embroidery process whereby a sewing machine or embroidery machine is used to create patterns on textiles. It is used commercially in product branding, corporate advertising, and uniform adornment. It is also used in the fashion industry to decorate garments and apparel. Machine embroidery is used by hobbyists and crafters to decorate gifts, clothing, and home decor. Examples include designs on quilts, pillows, and wall hangings.

To create free-motion machine embroidery, the embroiderer runs the machine and skillfully moves tightly hooped fabric under the needle to create a design. The "feed dogs" or machine teeth are lowered or covered, and the embroiderer moves the fabric manually. The embroiderer develops the embroidery manually, using the machine's settings for running stitch and fancier built-in stitches. In this way, the stitches form an image on a piece of fabric. An embroiderer can produce a filled-in effect by sewing many parallel rows of straight stitching. A machine's zigzag stitch can create thicker lines within a design or be used to create a border. Many quilters and fabric artists use a process called thread drawing (or thread painting) to create embellishments on their projects or to create textile art.

Most modern embroidery machines are computer controlled and specifically engineered for embroidery. Industrial and commercial embroidery machines and combination sewing-embroidery machines have a hooping or framing system that holds the framed area of fabric taut under the sewing needle and moves it automatically to create a design from a pre-programmed digital embroidery pattern.

In 1973 Tajima introduced the TMB Series 6-needle (6 color) full-automatic color-change embroidery machine. A few years later, in 1978, Tajima started manufacturing the TMBE Series Bridge Type Automatic Embroidery machines. These machines introduced electronic 6-needle automatic color change technology.

In 1982, Tajima introduced the world's first electronic chenille embroidery machine, called the TMCE Series Multi-head Electronic Chenille Embroidery Machine. In the same year, they developed the automatic frame changer, a dedicated apparatus for rolled textile embroidery. Also in 1982, Pulse Microsystems introduced Stitchworks, the first PC based embroidery software, and the first software based on outlines rather than stitches. This was monumental to decorators, in that it allowed them to scale and change the properties and parts of their designs easily, on the computer. Designs were output to paper tape, which was read by the embroidery machine. Stitchworks was sold worldwide by Macpherson.

In the late 1990s, Pulse Microsystems introduced networking to embroidery machines. It added a box, which allowed them to network and then pull designs from a central server. It also provided machine feedback, and allowed machines to be optically isolated to protect machines in an industrial environment. Since then, computerized machine embroidery has grown in popularity as costs have fallen for computers, software, and embroidery machines. Many machine manufacturers sell their own lines of embroidery patterns. In addition, many individuals and independent companies also sell embroidery designs, and there are free designs available on the internet.

A person who creates a design is known as an embroidery digitizer or puncher. A digitizer uses software to create an object-based embroidery design, which can be easily reshaped and edited. These files retain important information such as object outlines, thread colors, and original artwork used to punch the designs. When the file is converted to a stitch file, it loses much of this information, rendering editing difficult or impossible.

Finally, the embroidery machine is started and monitored. For commercial machines, this process is more automated than for the home machines. Many designs require more than one colour and may involve additional processing for appliques, foam, or other special effects. Since home machines have only one needle, every colour change requires the user to cut the thread and change the colour manually. In addition, most designs have one or more jumps that need to be cut. Depending on the quality and size of the design, sewing a design file can require anywhere from a few minutes to over half a day.
