"Denier" is the term used to define the diameter or fineness of a continuous or filament fiber such as silk or man-made fibers. Denier is the weight in grams of a 9000-meter length of fiber or yarn. The higher the number, the thicker the fiber. (source: http://www.dielectrics.com/technology.html)

RF (Radio Frequency) Welding The principle behind the process is the use of high frequency radio energy to produce molecular agitation in thermoplastic materials (ie:, polyurethane or pvc) to the point where they literally weld together, typically forming a bond that is as strong as the original material. To achieve the weld, sheets of flexible material are placed between a machined brass die (with raised areas representing the desired weld pattern) and a platen on the RF machine. The head of the machine comes down and generates pressure. The RF comes on and is channeled through the material in the pattern areas only, fusing the materials together at those points.
