Hemp Fabric

Hemp fabric earns its eco reputation in the field, not on the cutting table. The plant grows dense enough to crowd out weeds without herbicide, matures in around 100 to 120 days, and needs only a fraction of the irrigation a cotton crop uses over a season, all without the fungicide and insecticide treatments conventional cotton often requires. The fiber comes off the stalk as a bast fiber, similar in principle to flax, and gets processed into yarn coarser and stronger than cotton.

Almost none of the hemp fabric on the market is pure hemp — most is cut with cotton, commonly close to a 55/45 hemp-to-cotton ratio, because 100% hemp jersey is hard to source at production scale and drapes stiff on its own. A blend like that prints cleanly on a screen press once the goods have had a wash or two to open the weave; straight off a fresh roll, ink can sit unevenly on the coarser hemp yarn.

Ask for the actual blend ratio before quoting a sustainability claim: more hemp means more of that water and pesticide savings but a stiffer hand and a higher price; more cotton softens the hand and eases printing but only holds its low-impact story if that cotton is organic too.

Buyers hear "hemp" on a hangtag and assume the whole shirt earned its eco claim. If the blend's cotton share is conventional, non-organic cotton, the water and pesticide savings only cover the hemp portion of the fabric — a 55% hemp shirt with 45% conventional cotton is a partial improvement, not a fully low-impact fiber.
