Why bamboo t-shirts stretch and lose shape
Short answer: Bamboo t-shirts stretch and lose shape when the viscose is pulled while wet, when they are hung by the shoulders or when they are washed and dried too hot. With the right washing and drying the shape often lasts well.
Why bamboo t-shirts lose their shape
Bamboo in clothing is viscose made from bamboo, and viscose gets weaker when it is wet. That means bamboo t-shirts are pulled out of shape more easily than dry fabric. Once you know the causes they are easy to avoid, and the t-shirt stays tidy for longer.
Wet viscose gives way
The most common cause is that the shirt is pulled or hung up while it is wet. The weight of the water drags at the fabric and makes it longer. Take it out of the machine at once and lift it gently. Look at bamboo T-shirts for men and remember that they need a little more care than thick cotton.
The hanger and the shoulders
Hanging a wet t-shirt by the shoulders on a hanger drags the fabric downward and leaves a long shirt with bumps at the shoulders. Lay it flat on a drying rack or a towel instead, or fold it over a rail at the middle. That spreads the weight evenly, and the shoulders keep their shape.
Hot washes and the dryer
High heat can make viscose shrink in length and go slack in width, so the shape changes. Use a gentle programme at a moderate temperature and skip the tumble dryer if the label does not allow it. Hard drying wears on the fibres and can leave a limp shirt.
Hard spinning and wringing
A strong spin and wringing pull at wet fibres and can stretch the t-shirt. Use a low speed and press the water out with a towel instead of wringing. It takes an extra minute but protects the shape, especially at the neck and sleeves, where the fabric is under most strain.
The neck and the hem
The neckline is often stretched when you pull the shirt over your head, and the hem when you tug at it. Take hold of the shoulders and not the neckline when you take it off. If the neck has already gone slack, a little steam from an iron on a low setting can help, if the label allows it.
Use and rotation
If you wear the same t-shirt every day, it wears out faster. Rotate between several so the fabric can rest between uses. Close-fitting garments such as bamboo long johns can work as a layer, so a single t-shirt does not carry all the strain on cold days.
Size and washing together
A t-shirt that is too small is stretched every time you put it on, and that wears the fabric quickly. Choose a size that gives a little room. Do not wash it with heavy items such as jeans, and think of socks like all bamboo socks for men, which can go in the same machine.
Frequently asked questions
Can a limp t-shirt be rescued?
Sometimes you can get part of the shape back by washing it at a low heat and drying it flat. It does not always work, so prevention is better.
Why does the neck get long?
Because it is stretched when you put the shirt on and take it off. Grip the shoulders rather than the neckline, and do not hang it up by the neck.
Should I dry the t-shirt flat?
Yes, it is the gentlest way, especially while the fabric is wet. Only hang it up if you fold it over a rail at the middle.
