Textile yarn spun and twisted from staple length fiber, either natural or synthetic. Yarns of one filament are referred to as mono-filament yarns of several filaments as multi-filament. Synthetic yarn composed of one or more filaments that run the whole length of the yarn.
Or flanged bobbins are used for parallel winded yarn packages Or cops are the most flexible base for a wide range of package shapes (e.g.: cylindrical - no taper / biconical - double taper / single taper / bottle shape), depending on the winding unit (type of winding)
