How to Stop a Blanket Shedding After Washing

If you keep blankets at home, you may recognise a recurring issue: as soon as one comes out of the washing machine, it starts shedding heavily, scattering lint across the floor and sometimes even blocking the appliance filter. This can be linked to the selected cycle, the detergent used, the blanket material and even the drying method, but a few straightforward adjustments to your laundry routine can greatly reduce it.

Why does a blanket shed so much after washing?

The large amount of shedding after washing is directly associated with mechanical wear on the fibres, which becomes worse when the machine runs at a high spin speed and produces excessive suds. With older blankets or those that have already seen heavy use, the effect is usually stronger, resulting in a greater amount of lint.

Powder detergent residue that builds up between the threads can make the fabric stiff, encouraging further lint shedding in later washes. Very hot water, concentrated products and an overloaded drum also create more friction, speeding up fibre breakage.

How do high spin speeds and powder detergent affect blanket fibres?

Using a fast spin cycle alongside too much powder detergent forcefully compresses and twists the blanket, breaking microfibres that later show up as lint. If the detergent does not dissolve properly, it becomes trapped in the weave, dries out the fabric and makes the threads more likely to break during subsequent washes.

To lessen this effect, many manufacturers advise gentler programmes, with a medium or low spin speed and preferably liquid detergent. It is also worth adapting a few parts of the wash to protect the blanket’s structure more effectively:

• Select the delicate-items programme or a blanket setting, where your machine offers one.
• Lower the spin speed, even if this makes drying take slightly longer.
• Measure the cleaning product according to the water level specified by the manufacturer.
• Do not use harsh additives, such as chlorine bleach on coloured or synthetic items.

What are the washing-care differences between microfibre, sherpa and wool blankets?

The material has a direct effect on how the blanket responds to washing and on how much it sheds. Microfibre, usually made from polyester, is lightweight and hard-wearing, but can develop pilling and lint when exposed to high temperatures or excessively long cycles.

Sherpa blankets mimic sheepskin wool, with a deep, dense pile that makes them especially cosy but vulnerable to friction and vigorous spinning. Natural or blended wool, meanwhile, may shrink, felt and shed fibres if washed in very hot water or on unsuitable programmes.

Which habits reduce shedding, protect the washing machine and extend a blanket’s life?

Washing a blanket with towels is a common practice that makes shedding worse, because towels have a looped surface that acts like “soft sandpaper” inside the drum. Combining heavy items also puts extra strain on the motor, raises internal agitation and increases fibre wear.

To minimise shedding, prevent the washing machine filter from becoming blocked and retain softness for longer, always check the care label. Wash the blanket on its own or with items of a similar texture, clean the filter after heavier loads, and dry it in a well-ventilated shaded place. Turn it over a few times to prevent trapped moisture and odours.
