Embroidered semi-finished products and embroidery techniques

Abstract

Since antiquity, embroidery has been known as a familiar textile method for applying yarns to textile surfaces, mostly as decoration. There are many variations as to the manner and direction in which the yarn material is placed and how much of it is used. Owing to modern drive and calculation technology, embroidery machines offer nearly unlimited pattern variety at high productivity and reproducibility. One enhancement of embroidery technology is constituted by Tailored Fiber Placement (TFP). This technically fully developed method enables a targeted local reinforcement or functionalization of textile semi-finished products and the production of textile preforms with required reinforcement yarn arrangement for the manufacture of fiber composite components. This chapter provides an insight into the embroidery technology of technical textiles for fiber composite applications. It will deal with process-relevant parameters regarding mechanical properties and conveys an overview of two- and three-dimensionally embroidered semi-finished products. The potential of semi-finished products and preforms functionalized with embroidery technology will be illustrated by examples.
