Hemp in clothes: a plant fibre worth knowing

Why it matters for your body

Hemp cloth is a plant fibre from the stalk of the hemp plant. European fibre names call that strand true hemp, and they keep it separate from Manila hemp, which is a different plant (EU textile fibre names, Annex I). Think of it as linen’s neighbour: long fibres from the bark of the stem, spun into yarn.

On skin it behaves like other plant cloth. Air moves through it. A new piece can feel crisp, then soften with washing and wear. That hand comes from how the fibre was freed from the stalk. A review of hemp for textiles treats retting, the step that loosens the fibre from the woody core, as the point that decides how even the yarn can be (Zimniewska, Materials, 2022). Crisp is not a warning. It is unfinished softness.

The hangtag trap is a different fibre using the plant name. Hemp viscose or hemp rayon is pulp that has been dissolved and spun again. That is the viscose process. If the generic name is actually lyocell, read the lyocell page. This page is the bast fibre only.

The public read: Better choice

True hemp: Better choice.

Better choice means the bast fibre is a sound default for clothes that sit on skin. It is not a medical claim, and it is not a promise that the dyehouse was gentle. Farm marketing often calls hemp a lower input crop than conventional cotton. That can be a real difference in the field. It still does not describe the finish on the shirt in your hand.

Dye, finish, and the stretch line

Hemp takes dye, and it can be given the same easy care finishes as cotton: wrinkle resistance, stain resistance, extra softener. Those are finish questions. A water resistant or stain resistant claim is where you slow down, on hemp the same as on any other plant cloth.

GOTS can cover organic hemp because it is a processing standard for certified organic natural fibres (GOTS). OEKO-TEX Standard 100 tests an article for harmful substances and sets limits by how much skin contact the product is meant to have (OEKO-TEX Standard 100). Useful checks. Neither badge raises a TFD health number. A GOTS mark does not erase an elastane line, and an OEKO-TEX mark does not turn hemp viscose into bast hemp.

Blends are normal. Hemp with cotton is still plant cloth, and you read both names. Hemp with elastane is a plant fibre plus a stretch plastic. The hemp line can stay Better choice while the elastane line stays Prefer less.

What to look for on the label

• Hemp, or true hemp: the bast fibre. Public read: Better choice.
• Hemp viscose or hemp rayon: dissolved pulp. Read the viscose page.
• Lyocell made from hemp pulp: a solvent spun fibre. Read the lyocell page.
• Cotton or linen next to the hemp: a plant blend. Still check finishes.
• Elastane, spandex, or Lycra: a separate plastic line.
• GOTS or OEKO-TEX: process and limit checks, not a health number raise.

How to read a clothing label is the short version when the hangtag is mostly adjectives.
