Definition
A drawn sliver is a fiber sliver that has been further processed in a drafting system by controlled drawing to parallelize the fibers it contains and bring the sliver to a more uniform linear density. Multiple slivers are combined (doubled) and drafted together, which compensates for irregularities. The result is a refined, oriented fiber sliver with improved evenness that serves as a semi-finished product for subsequent spinning processes.
Use in the textile industry
In the spinning process, the drawn sliver is typically used after carding or combing and passes through several drafting passages to achieve the required evenness. It forms the basis for roving production on the flyer or speed frame and is equally relevant for staple fibers such as cotton, wool, and man-made fibers. High evenness of the drawn sliver is critical for yarn properties such as count variation and tensile strength.
