Embroidery technique

A particular importance is placed on the position of the conductive yams in order for it to connect the sensors to the power source without restraining the wearer s mobility. Often, the yarns alone will be placed along the seam so they will not be felt. In this case, the embroidery technique is often used and allows the conductive yams to be kept in place thanks to another thinner, nonconductive yam as shown in Fig. 23.1. The weaving or knitting techniques are also possibilities if the position of the conductive yam is predetermined. 

Conventional components are implemented into a textile substrate, eg, flexible planar circuit board. These conventional components could be sensors, OLEDs, and actuators. The circuit can be achieved by three methods (1) weaving conducting wire, (2) sewing and embroidery technique, and (3) screen print and inkjet. 

Combined embroidery techniques mean that, apart from the ground material and basic embroidery, other additional materials and techniques are used. These products are still categorized as embroidery, even though other techniques such as padding, shearing, etc. are also involved. This is explained by the fact that these are primarily embroidery products. All other techniques are subordinate and merely serve the purpose of the embroidery process, exercising no major influence on the end result. 

Furthermore, even though the machines are mechanically different, they both use a similar embroidery technique. Moss embroidery is created by a single-thread system. In this system, the needle goes through the carrier material and pulls the thread out... 

The chain stitch, also known as the Ari stitch, is similar to crochet and is generally used for kettle and moss embroidery. Moss embroidery machines are built differently than traditional embroidery machines however, they use a similar embroidery technique. Moss embroidery is created by a one-thread system. In this system, the needle goes through the carrier material and pulls the thread out from under the needle, plate side up (Figure 7.6). Then, a loop is created by a rotary motion of the needle on the upper side of the carrier material. Repeating this pattern frequently produces a mosslike surface.
