How to Stop a Blanket Shedding After Washing

People who keep a blanket at home often notice the same recurring issue: once it comes out of the washing machine, it sheds heavily, leaves lint across the floor and can even block the appliance filter. This can be linked to the selected wash cycle, the type of detergent, the blanket material and even the drying method, but a few straightforward changes to the laundry routine can greatly reduce it.

Why does a blanket shed so much after washing?

Heavy shedding after washing is closely associated with mechanical wear on the fibres, particularly when the machine uses a high spin speed and produces excessive foam. With older or heavily used blankets, the problem is usually more pronounced, resulting in larger amounts of lint.

Powder detergent residue trapped between the fibres can make the fabric stiff and encourage further lint shedding during later washes. Very hot water, concentrated products and overloading the drum also increase friction, speeding up fibre breakage.

How do high-spin cycles and powder detergent affect blanket fibres?

Using a high spin speed alongside an excessive amount of powder detergent compresses and twists the blanket forcefully, breaking microfibres that subsequently appear as lint. If the detergent does not dissolve properly, it remains within the weave, dries out the fabric and makes the threads more likely to break in future washes.

To limit this damage, many manufacturers advise gentler cycles, using a medium or low spin speed and preferably liquid detergent. A few other parts of the process should also be adjusted to protect the blanket's structure:

• Select the delicates programme or a blanket-specific setting, where the machine has 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 directly affects how a blanket responds to washing and how much it sheds. Microfibre, generally made from polyester, is lightweight and durable, but can develop bobbling and lint when exposed to high temperatures or very long programmes.

Sherpa blankets replicate sheepskin wool and have a deep, dense pile. Although especially cosy, they are sensitive to rubbing and vigorous spinning. Natural or blended wool, meanwhile, may shrink, felt and shed fibres if washed in overly hot water or unsuitable cycles.

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, since towels have a looped surface and act like “soft sandpaper” inside the drum. Combining heavy items also puts extra strain on the motor, raises internal agitation and increases wear on the fibres.

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