Standard Staple Yarn Spinning Procedures

Air-Jet Spinning Open-End Spinning Ring-Spinning Yarn Textile School / June 21, 2011 / Leave a Comment

Yarn making from staple fibers involves picking (opening, sorting, cleaning, blending), carding and combing (separating and aligning), drawing (re-blending), drafting (drawing into a long strand) and spinning (further drawing and twisting). Silk and synthetic filaments are produced by a less extensive procedure. Current high-production yarn-making operations are performed on integrated machines that perform this entire sequence as one combined operation.
