Single jersey, used in the majority of T-shirts and lightweight knit apparel worldwide.
Weft knit uses one yarn traveling horizontally (jersey, rib, interlock). Warp knit uses multiple yarns vertically (tricot, raschel). Weft knits run; warp knits are more stable.
Single jersey curls at the edges due to the loop structure - a defining behavior that complicates sewing. Controlled by starching, edge coating, or fabric weight selection.
Loops relax in the wash, especially first wash. Knits typically shrink 3-7% on first wash, more than wovens. Pre-shrunk or sanforized knits shrink less.
A ring-spun yarn produced with a suction zone that reduces hairiness by 30-50%. Better pilling resistance and smoother hand. Used in premium knits where surface quality matters.
