Scientists reveal the surprising secret to UNSHRINKING clothes after a laundry mishap

No matter how hard you try, some clothes inevitably shrink in the wash.

And it can be devastating to see your favourite shirt or dress shrivel before your eyes.

While many might simply just throw them away at this point, experts have now revealed there might be a way of saving them.

And all your need is a common bathroom product.

Dr Nisa Salim, from the Swinburne University of Technology in Australia, said understanding more about the science of textile fibres can not only help you prevent the shrinkage of clothing, but might also help you 'rescue' the occasional garment after a laundry accident.

'If a favourite garment has shrunk in the wash, you can try to rescue it with this simple method,' she wrote on The Conversation.

'This process can't completely reverse extreme shrinkage but it can help recover some of the lost size, making the clothes wearable again.'

So, here's what to do next time your best jumper emerges from the wash 10 sizes smaller.

Dr Salim suggests soaking the shrunken item in lukewarm water mixed with hair conditioner or baby shampoo, at a measurement of around one tablespoon per litre.

Then, you can carefully stretch the fabric back into shape and dry it flat under gentle tension – for example, by hanging it on a drying rack.

This solution all comes down to the fibres that clothes are made of, she explained.

Common textile fibres, such as cotton and linen, are made from plants and are irregular and crinkled in their natural form.

During textile manufacturing, these fibres are mechanically pulled, stretched and twisted to make them straighten and align, creating long, smooth threads.

However, when these fibres are exposed to heat, moisture or mechanical action – for example, when in a washing machine – they have a tendency to relax and return to their natural state.

'This fibre memory is why some fabrics wrinkle so easily and why some of them may even shrink after washing,' Dr Salim said.

Her unshrinking method works because hair conditioners and baby shampoos contain chemicals called cationic surfactants.

'These will temporarily lubricate the fibres, making them more flexible and allowing you to gently pull everything back into place,' she said.

To minimise shrinkage, people could try using cold water, the lowest spin speed or the gentlest cycle available, she explained.

And when in doubt, choose a 'delicate' setting.

Textile scientists are now working on fabrics that resist shrinkage.

Promising innovations include blended yarns that combine natural and synthetic fibres.
