Fabric softener, does it help or not

Short answer: For bamboo clothing, fabric softener does not help. It leaves a film on the fibres, and that film makes the fabric worse at absorbing and moving moisture, which is one of the reasons to choose bamboo.

What fabric softener does

Fabric softener leaves a thin layer of fat on the fibre surface. It feels smooth and soft when clothes come out of the machine, but the layer also seals the fibre off from moisture. It builds up over several washes, so the effect grows the longer you use it. It affects the qualities of most popular for women.

Why the fabric loses its function

Bamboo viscose is known for absorbing moisture and moving it away from the skin. A fabric that cannot absorb moisture cannot move it either. Sweat then stays on the skin instead of spreading into the fabric. That is exactly the quality you choose a bamboo tank top for men for.

Bamboo is already soft

Many people use fabric softener to make clothes soft. But bamboo viscose has a smooth fibre that is soft in itself. It does not need softener to feel pleasant. If your clothes no longer feel soft, there is usually another explanation, and it is easier to fix.

Why the fabric turns stiff

If fabric turns stiff after washing, the cause is usually detergent residue or limescale from hard water. The residue dries into the fibres and hardens them. Softener only covers the problem with a film and does not remove the cause. That is why the stiffness returns as soon as you stop using it.

What to do instead

The simplest fix is an extra rinse. It removes detergent residue that would otherwise stay in the fabric. You can also try using a little less detergent than before. That solves it in most cases, also for bamboo sweatwear, where there is a lot of fabric to hold residue.

Air drying and softness

Air dried clothes can feel slightly stiff right after drying. That usually passes after a few minutes of wear, as the fabric warms up and moves with the body. You can also shake clothes well before hanging them and pull them into shape. That keeps the fibres looser as they dry.

How to remove the film

If you have used fabric softener for a long time, there is probably a film on the fibres. It can be washed out. Wash the clothes two to three times without softener, ideally with an extra rinse. That removes most of the layer, and the fabric absorbs moisture more easily again.

Check the drawer in the machine

Softener residue can sit in the detergent drawer and in the hoses of the washing machine. When you stop using it, it is a good idea to clean the drawer and run an empty wash. That way old residue does not end up in your next loads and form a new film.

Frequently asked questions

Does it also apply to towels

Yes. Fabric softener makes towels less absorbent for the same reason. The film on the fibres makes it harder for the fabric to take up water, so the towel dries you less well.

What about static electricity

Softener helps against static, but air drying solves the same problem without the film. Static mostly builds up in the tumble dryer, where clothes rub against each other.

Can the film be washed out again

Yes. Two to three washes without softener remove most of it. An extra rinse with each wash speeds this up, and the fabric absorbs moisture better afterwards.
