Not all yarns require sizing, only those prone to hairiness, abrasion, and breakage under loom tension. Spun yarns (cotton, viscose, polyester staple) usually need sizing, while smooth, continuous filament yarns (polyester filament, nylon filament) often do not. Proper sizing improves machine efficiency, fabric quality, and cost control. Advanced sizing systems like <a href=\"\/about\/\">Alpenol<\/a> make warp yarns smoother, stronger, and more stable at high loom speeds while requiring lower size add-on.<\/p>\n<h2 id=\"what-is-a-yarn\">What Is a Yarn?<\/h2>\n<p>A yarn is a continuous strand of textile fibers or filaments suitable for knitting, weaving, braiding, or sewing.
