Pilling
Treatment — one of 37 in the glossary
The small balls of tangled fibre that form on a fabric surface where it rubs, most visibly under the arms, at the waistband and on the back of a sweatshirt. Short fibres work their way loose, roll up and stay anchored by the longer fibres around them. It is driven by fibre and yarn choice rather than by wear alone: short-staple, open-end and blended yarns pill fastest, while combed ring spun, air jet and long-staple cottons resist it. Since customers read pilling as the garment wearing out, yarn quality is worth more than ounce weight on anything meant to last.
What is actually happening
Pills are short fibres that have worked their way to the surface, rolled into a ball under friction, and stayed anchored by the longer fibres still held in the yarn.
That description contains the whole story. A fabric pills when it has plenty of short fibre ends to shed and enough strong fibre to stop the pills falling off. It is why a cheap cotton-poly blend is the classic offender: the cotton sheds and the polyester holds the pills in place.
Pure wool pills too, but the pills break away, so it looks better for longer than a blend that traps them.
Which blanks pill fastest
Open-end carded yarns pill fastest, because they are full of short fibre ends by construction. Combed ring spun pills far less, because combing removed most of those ends before spinning.
Blends pill more visibly than either pure fibre, for the anchoring reason above. A 50/50 is the usual worst case in a blanks catalogue.
Where it shows first is predictable: under the arms, at the waistband, across the back of a sweatshirt where a chair rubs, and anywhere a bag strap sits.
What reduces it
Choosing the fabric. Combed ring spun over carded, and a single fibre over a blend, does more than any laundry habit.
Washing inside out, cold, on a gentler cycle and with a full load helps at the margin by reducing abrasion. So does line drying. None of it will save an open-end blend.
A garment already pilling can be shaved — a fabric comb or a battery shaver — which removes the pills without touching the fabric underneath. It is cosmetic, and it will need doing again.
Common questions
- What causes pilling on shirts?
- Short fibre ends working loose under friction, rolling into balls, and being held in place by the longer fibres around them. It is driven by how the yarn was made rather than by how the shirt is washed.
- Which fabrics pill the most?
- Open-end carded yarns and cotton-polyester blends. The cotton sheds short fibres and the polyester holds the resulting pills in place, which is why a 50/50 looks worse sooner than either fibre alone.
- How do you stop a shirt from pilling?
- Mostly by buying differently: combed ring spun cotton rather than open-end carded, and a single fibre rather than a blend. Washing inside out and cold helps a little; it will not rescue a fabric that was always going to pill.
- Does pilling mean a shirt is low quality?
- It means the yarn was built to a price, which is not the same thing. A heavy carded shirt can be tough and long-wearing and still pill under the arms.
