Lotus (Lotus Silk)
The rarest and most precious of the plant fibres used in knitting: cool and light like linen but noticeably softer, with a dry, breathable hand. It is a luxury for special garments, to be treated with care because it has no elastic memory.

History
It comes from the stems of the lotus flower and has its roots in the Buddhist tradition of Southeast Asia, where lotus cloth dressed statues and monks as a sacred offering. The historic centre is Inle Lake in Myanmar, where whole communities of weavers extract and spin the fibre by hand; similar production later took hold in Cambodia and Vietnam. Volumes remain tiny: a few metres of cloth take tens of thousands of stems and weeks of work, which makes it one of the most expensive natural fibres in the world.
How the yarn is made
The stems are gathered fresh, scored and snapped by hand: from the break emerge very fine filaments that the worker immediately rolls together, before they dry, into a continuous thread. The work must be done within a few hours of harvest, because the extracted fibre does not keep. There is no shearing and no extrusion: it is a slow handcraft that no machine has yet replaced, and this is the main reason for its rarity.
Why it is prized
It combines the coolness typical of bast fibres with a softness and lightness that raw linen does not reach. The slightly uneven thread gives a lively, breathable hand, ideal for summer garments that must stay cool on the skin. What makes it precious, even more than its performance, is its scarcity and the handwork it demands: every skein is in effect one of a kind.
Dyeing
Being cellulosic, it takes direct and reactive dyes well, with soft, natural results. Tradition often leaves it in its raw tone, a warm beige ranging from ivory to hazel, so as not to hide the handmade character of the thread. Pastel shades and plant dyes suit it better than saturated, flat colours.
Care
Treat it as a delicate, precious garment: hand wash in cold water with a neutral detergent, without wringing or twisting, and dry flat away from direct sun. It does not felt and sheds very little fuzz, but it gives under strain and does not recover: avoid hangers and prolonged tension, which would leave it stretched.
End of life
It is pure, untreated plant cellulose: fully biodegradable and compostable at end of life. Processing has a very low impact, with no solvents or heavy chemistry, and the leftover stems go back to the soil. Mechanical recycling makes little sense given its rarity: the value lies in keeping and mending the garment.
How to recognise it
| Hand | Cool and dry to the touch like linen, but softer and silkier, and remarkably light. The thread feels slightly uneven, never slippery or cold like a synthetic. |
|---|---|
| Look | Matt or faintly satiny, in a natural colour ranging from ivory to hazel. The thread shows small irregularities and a lively texture, the unmistakable sign of hand spinning. |
| Behaviour | It drapes fluidly and coolly, creases easily like other plant fibres and, when pulled, does not return: it has no elastic memory and tends to keep the stretch. |
| Burn test | Cellulosic signature: it burns quickly with a bright flame, smells of burning paper or leaves, and leaves a light, crumbly grey ash, without forming beads. |
| Home tests | Burn test: quick flame, smell of burning paper, crumbly ash · Wet stretch test: like plant fibres it holds up well to pulling when damp, unlike wool · Stretch test: pull and release, the thread stays stretched and does not bounce back |
| Confused with | Linen and ramie: cool and matt like lotus, but with a stiffer, wirier hand · Vegetable silk and viscose imitating its look: shinier, more even and slippery, and when wet they lose much of their strength, while lotus keeps it |
| Only in a lab | Telling lotus with certainty from other cellulosic bast fibres and identifying its structure requires laboratory microscopy (ISO 17751) and solubility tests (ISO 1833). |
