Technical Textiles

A technical textile is a woven or knitted material with extremely precise dimensions. They are produced for a specific, functional purpose, and not produced for aesthetic purposes. Technical Textiles are constructed from mono- and multi-filament polymer or fabric based yarns. This material is similar in function to an extruded netting, but greater precision can be reached through the weaving process. The highly accurate dimensions of Technical Textiles make precise filtration a common application for this material, amongst many other applications.
Technical textiles can be either knitted or woven. These manufacturing techniques are the basis for their subtype categorization.

Knit Technical Textiles

Knitting is one of the most commonly used technical textile manufacturing methods. Some of the most common types of finished knitted technical textile products include geotextiles, spacer fabrics, and more. Typically, knit fabrics are composed of one (or close to one) piece of yarn or thread. There are two main types of knitting: warp and weft. Warp knitting occurs when the yarn is knit along the length of the fabric. Conversely, weft knitting occurs when the yarn is knit along the width of the fabric. Warp knitting utilizes several different stiches, including the tricot and raschel stitch. Weft knitting utilizes stitches such as purl and knit stiches.

Woven Technical Textiles

Unlike knit fabrics, woven fabrics are manufactured from multiple yarns or threads that are systematically overlapped to form a grid-like structure. Due to their rigid pattern, woven fabrics possess lower elongation in the MD and CD direction.
