kuivakehräyksellä

Kuivakehräys, also known as dry spinning, is a textile manufacturing process used to produce synthetic fibers. In this method, a polymer solution is extruded through a spinneret into a heated chamber. The heat causes the solvent in the polymer solution to evaporate, leaving behind solid filaments. These filaments are then drawn and wound onto bobbins. Kuivakehräys is commonly used for polymers that can be dissolved in a volatile solvent. Examples of fibers produced by this method include acetate and acrylic. The process is characterized by its relatively simple equipment and ability to produce fibers with a wide range of deniers. The choice of solvent and the temperature of the evaporation chamber are critical parameters that influence the properties of the resulting fiber. Control over these factors allows for tailoring the strength, flexibility, and other characteristics of the manufactured yarn. This technique is a significant contributor to the production of various synthetic textiles.
