<\/figure>\nWhat a pill actually is<\/h2>\n
A pill is not worn out fabric. It is fabric that has moved.<\/p>\n
Every yarn in a sweatshirt is spun from short fibres twisted around each other. The twist is what holds them in place, and it holds them imperfectly.<\/p>\n
With use, the ends of those short fibres work their way out of the twist and stand up on the surface. That happens to every spun yarn ever made.<\/p>\n
Friction then rolls the standing ends around each other into a small tangled ball, and the ball stays attached because a few fibres in it are still anchored in the yarn.<\/p>\n
So the garment is not thinner where it pills. The fibre is still there, just gathered into knots instead of lying flat.<\/p>\n
That distinction tells you what to do about it. Reduce friction and you reduce pilling, and nothing else comes close to having the same effect.<\/p>\n
Where sweatshirts pill, and why those exact places<\/h2>\n
Under the arms first, every time. The underside of the sleeve and the side of the body are two fabric surfaces pressed together and moving against each other with every step.<\/p>\n
Along the sides below the arm, for the same reason. Arms swing against the ribs all day and that is thousands of small rubs.<\/p>\n
Across the upper back and over one shoulder, which is a backpack, a shoulder bag or a strap. A strap holds fabric against fabric under load, and load plus movement is the worst combination there is.<\/p>\n
The cuffs, which catch on desks, on the sleeves of a coat, and on each other when they are pushed up.<\/p>\n
The front hem, where it sits against a seat belt, a counter edge or a car seat.<\/p>\n
Nothing pills across the middle of the back or the centre of the chest, because nothing rubs there. The pattern is that literal.<\/p>\n
Why cotton and polyester blends pill worse than pure cotton<\/h2>\n
Pure cotton pills too. It just does not keep the pills it makes.<\/p>\n
A cotton fibre in a short length is not very strong, so the two or three fibres anchoring a pill snap under a bit of tumbling and the pill drops off in the wash.<\/p>\n
Polyester is much stronger for its thickness. The anchoring fibres in a blend do not break, so the pill stays attached and it keeps collecting more loose fibre.<\/p>\n
Which is why a cheap cotton and polyester fleece can look shabby after one season while a heavy all cotton one still looks reasonable, even though the blend is the more durable fabric in every other respect.<\/p>\n
The higher the polyester content the more of this you get. A fifty fifty blend shows it faster than an eighty twenty cotton.<\/p>\n
Yarn softness matters as much as fibre content. Loosely spun, very soft fleece has more fibre ends near the surface from the day it is made, which is why the softest sweatshirts on the rack are often the first to go bobbly.<\/p>\n
Washing sweatshirts inside out, the one habit that matters<\/h2>\n
Turn it inside out before it goes in the drum. That single change does more than everything else on this list combined.<\/p>\n
The outside of the garment is the face people look at. Inside out puts the inside face against the drum, against the zips and against the other clothes, and the surface that gets the abrasion is the one nobody sees.<\/p>\n
Do the same in the dryer, since the dryer is where a lot of the tumbling happens.<\/p>\n
Fasten every zip and hook in the load. An open zip pull is a small file dragging across fleece for forty minutes.<\/p>\n
Keep sweatshirts away from towels, from denim and from anything with a hook and loop fastener. Terry loops and raw denim are abrasive and hook tape is worse than either.<\/p>\n
Wash warm or cold rather than hot. Heat swells and relaxes the fibre and lets more ends migrate to the surface, and it does nothing useful on a garment that is mostly lightly soiled.<\/p>\n
Pick a shorter cycle where the machine offers one. Time in the drum is time under friction.<\/p>\n
Overloading, and what a packed drum does<\/h2>\n
A full machine feels like the efficient choice and it is the biggest cause of pilling that is entirely within your control.<\/p>\n
Clothes in a packed drum cannot move through water. They compress into a solid mass and grind against each other in place instead of tumbling.<\/p>\n
Grinding under compression is precisely the load that rolls loose fibre ends into balls, and in an overfilled machine it goes on for the whole cycle rather than in short bursts.<\/p>\n
Sweatshirts are bulky, so a load of them fills a drum faster than it looks like it should. Fill to about three quarters and leave room to lay a hand flat on top of the load.<\/p>\n
The same rule applies in the dryer, and it is ignored more often. An overloaded dryer rotates one heavy lump rather than separate garments, which is both slower and rougher.<\/p>\n
A half full drum on a normal cycle is gentler than a packed drum on a delicate one, which surprises people who have been relying on the setting to do the protecting.<\/p>\n
Fabric softener, and the fleece inside a hood<\/h2>\n
Fabric softener works by depositing a thin waxy layer on the fibre so it feels smooth to a hand. It does not make the fibre softer, it coats it.<\/p>\n
That coating accumulates wash after wash. On brushed fleece it flattens the raised pile and mats it into a dull board, and it holds loose fibre ends stuck to the surface where friction can get at them.<\/p>\n
It also reduces absorbency, which matters on sweatshirts because they are worn against skin on a warm afternoon.<\/p>\n
The fleece inside a hooded sweatshirt is raised fibre standing upright, and everything about a wash cycle works to lay it down. Once it has matted it does not come back fully, though a low heat tumble with a couple of wool dryer balls lifts some of it.<\/p>\n
White vinegar in the rinse gives you the soft feel without a coating, and it strips a little of the buildup while it is there.<\/p>\n
If a sweatshirt already feels waxy and looks flat, a hot wash with no detergent at all and half a cup of washing soda takes most of the residue off and is worth doing once before you decide the garment is finished.<\/p>\n
Taking the pills off without wrecking the fabric<\/h2>\n
Use a battery fabric shaver with a guard. It holds the blade a set distance off the fabric surface and cuts the ball without touching the weave underneath.<\/p>\n
Lay the garment flat on a table, pull the area smooth, and work in short passes in one direction. Never shave a garment while it is being worn or hanging, because slack fabric gets pulled into the head.<\/p>\n
Empty the catch tray often. A full tray stops the blade clearing and it starts dragging instead of cutting.<\/p>\n
A disposable razor works and it is the usual way people put a hole in a sleeve. There is no guard, so the blade sits on the fabric and cuts anchoring yarn along with the pill.<\/p>\n
A sweater comb or a pumice style block is slower and safer than a razor and fine for a small area.<\/p>\n
Dry on low heat and take the load out slightly damp. High heat is the setting that does the most fibre damage on fleece, and an over dried sweatshirt sheds more the next time it is worn.<\/p>\n
What you cannot undo is thinning. Shaving removes fibre permanently, so a garment that has been shaved several times gets visibly thinner and eventually goes sheer at the elbows and the sides. Most sweatshirts want this once or twice a year at the outside, not after every wash.<\/p>\n
The Boulder part<\/h2>\n
The air here is dry most of the year and dry air means static, which is the local factor that bears directly on this. Static is more than an annoyance in a dryer, because it changes how much friction a load takes.<\/p>\n
Charged garments cling to each other and to the drum instead of tumbling loosely, so the surfaces stay in contact longer and the rubbing is continuous rather than intermittent. Static also stands loose fibre ends upright, which is exactly the position in which they get rolled into pills.<\/p>\n
Cutting dryer time is the practical answer. Take the load out slightly damp, use wool dryer balls to keep garments separated, and add white vinegar to the rinse rather than reaching for a sheet, since a softener sheet solves the static by coating the fleece and that trade is a bad one on a sweatshirt.<\/p>\n
The other local factor is how much wear a sweatshirt gets here. Cold mornings and warm afternoons across a long spring and a long autumn mean a fleece top goes on and comes off daily for months at a stretch, which is a lot more use than a winter coat sees. That means more wash cycles, and cumulative cycles are where pilling comes from. Two sweatshirts in rotation halve the cycles on each, and the dry air means a heavy fleece laid flat indoors is dry in a few hours, so skipping the dryer entirely on the ones you care about is genuinely practical here.<\/p>\n
Where a fleece load has room to move<\/h2>\n
Most pilling on sweatshirts comes from garments grinding against each other in a drum that is too full, which is a question of machine size rather than technique.<\/p>\n
The machines at our self-service laundry on Broadway Avenue<\/a> hold a full winter load at three quarters full rather than packed, and that water volume lets a heavy fleece tumble freely instead of compressing against the drum for forty minutes straight.<\/p>\n Our machines and the store are cleaned daily.<\/p>\n Nou wash-dry-fold service<\/a> covers the everyday laundry.<\/p>\n
