Bobbling, also known as pilling, is a common issue with knitwear that many people find frustrating. While friction is a primary cause, several other factors contribute to the formation of those unsightly little balls of fibre on your favourite jumpers and cardigans.
What Causes Bobbling?
Bobbling occurs when short fibres on the surface of a fabric become tangled and form small balls. The type of fibre, the softness of the yarn, the stitch pattern, and washing methods all play a role. For instance, knit stitch (characterised by overlapping V shapes) tends to bobble more than garter stitch (with wavy horizontal lines). This is because fibres run vertically in knit stitch, making them more susceptible to horizontal friction.
The outside of a garment always experiences more friction than the inside. Your arms rubbing against the body of a cardigan, a bag strap, or a seatbelt can all cause pilling. The inside is more protected, being closer to your body and often covered by an underlayer like a T-shirt.
Softer fibres such as acrylic, merino wool, and loosely spun yarns pill faster than rustic Norwegian wool. Synthetic knitwear, which dominates the high street, is particularly prone to bobbling.
How to Prevent Bobbling
One simple preventive measure is to wash your garments inside out. This reduces friction on the outer surface and protects the fibres. For woollens, using a gentle cycle and a mild detergent can also help. Additionally, choosing garments made from tightly spun, long-staple fibres can minimise pilling.
How to Remove Bobbles
If bobbles have already formed, there are several effective removal methods:
- Electric debobbler: A battery-powered device that glides over the fabric, shaving off pills. The sound is oddly satisfying.
- Disposable razor: An old razor can be used to shave bobbles off, but keep the fabric taut to avoid damage.
- Lint roller or tape: For light pilling, a lint roller can pick up loose fibres.
- Fabric comb: A special comb designed to lift and remove pills.
One reader suggests making firelighters from harvested bobbles. Combine the lint with molten wax in an egg box to create effective fire starters.
Expert Tips from Readers
Readers have shared their own experiences and advice. Daisy Robinson notes that the inside of her cardigans never bobbles, suggesting that wearing the garment inside out could be an option, though it may look odd. Another reader, HemingfieldTwit, washes all clothes inside out for protection. FrankieandDexy encountered a cotton sweatshirt that started bobbling after just two days of wear, highlighting how quality varies.
In conclusion, bobbling is a natural phenomenon that can be managed through careful washing, choosing the right fabrics, and using simple removal tools. With a little effort, your knitwear can stay looking new for longer.
