Training course in wet spinning (solution spinning) of man-made fibers
This course will provide you with essential knowledge of the fundamentals of wet spinning technology used in man-made fiber production. We cover both traditional wet and air-gap (dry-jet wet) spinning, guiding you through the entire process from polymer dissolution to ready yarn, focusing on key considerations that arise during process upscaling.
Purpose
The purpose of the course is to provide you with a comprehensive overview of wet and air-gap spinning processes, highlighting key technological developments. We cover the essential stages, starting with polymer dissolution (dope preparation) and its characterization, and guide you through the steps required to produce filament or staple fibre yarn. You will learn about common challenges encountered during process upscaling and receive practical advice on how to address them. The course primarily focuses on man-made cellulosic fibers, but the content can be customized to meet your company's specific needs. Depending on the desired content and format, by the end of the course, you can gain a deeper understanding of the process, acquire hands-on experience in wet spinning, learn about tools for effective dope and fiber characterization, etc.
Target Audience
The course is oriented toward companies in the early stage of developing their wet (air-gap) spininning technology. It is primarily designed for researchers, engineers, technicians, and operators involved in process development. An academic degree in material science, chemistry, chemical engineering, polymer technology or related fields is advantageous but not mandatory. The course is also valuable for professionals in marketing, sales and business development who seek a deeper understanding of the technology.
Format
The course is organized on demand and is given exclusively to a group of participants from your company. Therefore, the contents can be customized to meet your company’s specific needs. The typical group size is 3 to 10 participants. The course can be conducted either on-site at RISE in Mölndal, Sweden, or digitally. The typical course duration is 1 day for theory or 2 days for theory and practice.
