Hank (textile)

In the textile industry, a hank is to a unit of yarn or twine that is in a coiled or wrapped form (as opposed to other forms such as a ball or a cone or a bobbin or a spool). This is often the best form for use with hand looms, compared to the cone form needed for power looms. Hanks come in varying lengths depending on the type of material and the manufacturer. For instance, a hank of linen is often 300 yards (270 m), and a hank of cotton or silk is 840 yards (770 m).

While hanks may differ by manufacturer and by product, a skein is usually considered 1/6th of a hank (either by weight or by length). One source identify a skein of stranded cotton as being 8.25 yards (7.54 m), of tapestry wool as being 10 yards (9.1 m), and crewel wool as being 33 yards (30 m).[1]

In yarns for handcrafts such as knitting or crochet, hanks are not a fixed length but are sold in units by weight, most commonly 50 grams. Depending on the thickness of the strand as well as the inherent density of the material, hanks can range widely in yardage per 50 gram unit; for example, 440 yards for a lace weight mohair, to 60 yards for a chunky weight cotton. Special treatments to the materials that add cost, such as mercerisation or labor-intensive hand-painting of colors, can influence a manufacturer's desired length per unit as well. Knitters and crocheters rewind the hanks into balls or centre-pull skeins prior to use, in order to prevent the yarn from becoming tangled.[citation needed]

Hog casings are sold in "bundles" or "hanks." This unit of measure equals 100 yards (91 m).
