The plant's journey to underwear, step by step

Short answer: Underwear made from bamboo starts as a bamboo plant that becomes cellulose, then viscose fibres, yarn and finally knitted fabric, which is cut and sewn into knickers and tops. Here is the journey in broad strokes, without promising anything about a particular factory.

From bamboo plant to cellulose

Underwear made from bamboo begins with the plant itself, a fast-growing type of grass. The bamboo stalks are broken down so that cellulose, the building material of the plant, can be extracted. That cellulose later becomes fibres, so the finished fabric is not raw bamboo but a processed fibre.

From cellulose to viscose fibres

The cellulose is dissolved and pressed through tiny holes so that long, thin fibres form. This is called viscose, and when it is made from bamboo it is often called bamboo viscose. The fibres are smooth, and that is one of the reasons underwear made from bamboo can feel soft against the skin.

From fibre to yarn

The fibres are spun together into yarn, which is long threads that can be knitted. How thick the yarn is and how tightly it is spun affects how the finished fabric feels and drapes. The yarn can be blended with other fibres to give stretch, so the underwear can follow your body and move with you.

From yarn to fabric

The yarn is knitted into fabric on large machines, where threads run in tight loops. The knit gives the fabric its flexibility and is the reason underwear can stretch and return to shape. This is also where it is decided how dense and thick the fabric becomes and how well it fits the body.

From fabric to knickers and tops

The fabric is dyed, cut into pattern pieces and sewn together. How many seams there are and how they sit matters for comfort. Look at our bamboo underwear for women if you want to see how different styles are built and where the seams lie.

What it means for you as a wearer

When you know the journey it is easier to understand why you should wash according to the label and why seams and fit matter. Viscose is a cellulose material and can react to heat and rough handling. So follow the care instructions, and the underwear will keep its shape for longer.

What to be critical about

A product's origin and manufacture can vary, and not every claim is equally good. Read the product description and the label, and ask the shop if you are unsure about the material. Look at the composition, not only at the word bamboo, so you know exactly what is in your clothes.

How to look after the finished clothes

Wash the underwear on a gentle programme, avoid high heat and let it dry flat or on a rack. Combine with bamboo T-shirts for women and bamboo socks in the same wash if the instructions match. That gives the whole soft basic set a longer life.

Frequently asked questions

Is bamboo underwear made from raw bamboo

No, bamboo in clothing is viscose, where cellulose from the plant is turned into fibres. The finished fabric is therefore a processed fibre, not raw bamboo.

Why does bamboo feel soft

Viscose fibres have a smooth surface, and that can give a soft feel. Knit, seams and fit matter at least as much as the fibre itself.

What should I look for on the label

Look at the composition and the care instructions. There you can see what the fabric is made of and how best to look after it.
