Zips and hook and loop fastenings that ruin bamboo fabric in the wash

Short answer: Open zips and hook-and-loop fasteners snag thin fibres throughout the whole cycle. Close them before washing, or put fine items in a wash bag.

What happens in the drum

During a wash cycle, clothes keep moving and rub against each other constantly. An open hook-and-loop fastener grabs onto every loop it meets along the way, and an open zip acts like a row of small hooks. The result is pulled threads and small holes in the thinnest fabric after just one wash.

The two minutes before washing

Close every zip, press hook-and-loop fasteners flat, and do up buttons fully. Turn jackets and trousers inside out before they go into the drum. It only takes two minutes and noticeably extends the life of thin garments in the same load, without adding any real time to your routine.

A wash bag for fine items

A fine mesh wash bag protects underwear, bras and thin t-shirts throughout the whole cycle. Do not pack the bag too full, since clothes still need room to move to actually get clean. See bamboo underwear for women for fabric that handles this treatment well time and again.

Sort by how rough it is

Wash jackets, workwear and anything with hard details separately in its own load. Keep underwear, sleepwear and t-shirts in their own wash every time. See bamboo sleepwear for women and bamboo t-shirt for women for garments that do best without hard neighbours in the drum.

Why hook-and-loop fasteners are the worst

Hook-and-loop grabs anything with a loose loop or thread, and that includes drawstrings, knitted edges and even other hook-and-loop fasteners in the same load. A single open strip can therefore damage several garments at once, not only the one the strip itself is attached to from the start.

What about metal buckles and eyelets

Metal parts like buckles, eyelets and buttons with sharp edges can also scratch soft fabric if they hit it directly throughout the spin cycle. Turn that kind of garment inside out, and place it toward the outside of the drum, where it touches other clothes the least over time.

When to use a gentle cycle

Using a cycle with low spin speed and slower drum movement for fine items further reduces the damage from open details. See bamboo t-shirt for women and choose a gentle cycle whenever you mix thin fabric with clothes that have buckles, zips or hard studs.

Can the damage be repaired afterward

Pulled threads can often be gently eased back into place with a sewing needle, if caught early enough. Small holes are harder to fix invisibly. Prevention is therefore far more effective than repair, especially on thin fabric, where even minor damage is hard to hide completely.
