Mean fabric weight refers to the average fabric weight of all yarn types in term of fabric structure. Mean UPF refers to the average of UPF all yarn types in term of fabric structure. Statistical relationship for all single knitted structures (plain, pineapple, lacoste, KT11, KM11, KT22W, KM22W, KT22C, and KM22C) with all yarn types. Statistical relationship for all double knitted structures (half milano, full milano, half cardigan, full cardigan, 1 × 1 rib, and interlock) with all yarn types.
