The heavy coat comes out of storage at the first cold snap, and nine times out of ten the cloth is in better shape than the things holding it shut. The body is dense wool. It copes with weather, with years of wear and with a careful wash now and again. The fastenings are another matter: a barrel of wood or horn, a loop of leather or braided cord, and a few stitches or a single rivet holding that loop to the cloth. Three or four unlike materials, each with its own answer to water and warmth, all expected to work as one thing.
Three materials in one fastening
Before anything else, it is worth looking at what you actually have, because these are built several ways. The barrel is usually wood, sometimes horn, sometimes a molded imitation of either. The loop is leather, braided cord or a rolled tube of the coat fabric. The loop is attached either by stitching through a small tab or by a rivet set through the cloth. Any combination of those is normal.
A garment is at its most durable when it is one material behaving one way. Every junction between unlike materials is a place where two different rates of movement meet. Wool swells a little in water and relaxes. Wood swells a lot and unevenly. Leather shrinks when it dries warm. Put all three within an inch of each other and something has to give at each wash.
That is the short explanation for why a toggle fastening goes first on a coat that is otherwise sound. It is not that they are made badly. It is that the wash which suits dense wool is not the wash that suits wood, and neither of those is the one that suits leather, and nobody gets to choose three different treatments for one garment.
What water does to wood
Wood is cellulose fiber held in a matrix of lignin, and those fibers all run roughly one direction. It takes up water readily and swells as it does, but it swells much more across the grain than along it. That unevenness is the root of everything that goes wrong with a wooden barrel, because the piece grows in one direction while holding its length in the other.
Repeated wetting and drying builds stress into the piece. Each cycle swells it and shrinks it again, never quite back to where it started, and eventually small splits open along the grain. These are called checks, and they start where the stress is highest. On a toggle that means the drilled holes, because a hole interrupts the fibers and concentrates stress at its edges.
Warm drying is the harsher half of the cycle. The outside of the piece dries and tries to shrink while the inside is still wet and still swollen, which puts the surface in tension against a core that will not let it move. Wood answers tension across the grain by splitting. This is why a barrel that went through a warm dryer can come out cracked from a hole to an end.
Most wooden barrels are lacquered or oiled, and while the finish is intact it slows water down considerably. The trouble starts once the finish has its first hairline crack, usually at a hole. Water now has a route in and a poor route out, so the inside of the piece takes up moisture and holds it while the surface looks dry and sound.
Horn behaves like wool does
Horn is keratin, the same protein family as wool and hair, laid down in overlapping sheets. That origin tells you most of what you need to know, because anything that damages wool damages horn in the same way and for the same reasons. The difference is that a horn barrel is solid, so damage shows as warping and dulling rather than as shrinkage.
Keratin softens when it is warm and wet. A horn barrel in a warm wash can lose its curve, twist slightly, or go a little translucent along an edge, and none of that comes back when it cools. Dry warmth does the opposite and drives moisture out of the material until it goes brittle, and a brittle barrel snaps across a hole at the first hard pull.
Strongly alkaline detergent attacks the protein directly, breaking the bonds that hold the sheets together. The early sign is a chalky, dull surface where there was a polished one. Later the layers begin to separate at an end, which is delamination, and once a horn piece is lifting in layers there is nothing to be done with it.
If you are not sure whether a barrel is horn or a molded imitation, weight and surface tell you more than color. Horn is cool to the touch, slightly uneven in its markings and often shows fine lengthwise lines. Imitations tend to have a seam or a sprue mark somewhere and a repeating pattern. Treat an unknown barrel as though it is horn.
Leather loops, stitched or riveted
Leather is collagen fiber stabilized by tanning, and it has a particular response to being wet and then dried in warmth. The fiber network draws together and sets in the drawn position, so the piece comes out smaller, harder and less willing to bend. On a coat this is immediately obvious, because a loop that has shrunk will no longer pass over the barrel it was sized for.
Stiffness does the second kind of damage. A loop that used to bend along a gentle curve now has one hard point where it folds, and leather that is stiff cracks at that point rather than flexing through it. The crack starts on the outside of the bend, works inward, and the loop eventually parts there. You can usually see the line before it gives.
A stitched loop carries its load through the thread, and the thread passes through punched holes in the leather. Each hole is a small stress concentration, and wet leather is softer than dry leather, so the thread presses into the hole and begins to cut rather than to hold. Over enough cycles the row of holes becomes a tear line, and the loop lifts away from the tab as a strip.
A rivet spreads its load over the area of its head and washer, which is a better arrangement in principle, but it has no give at all. The cloth and leather around a rivet cannot stretch to share a sudden pull, so when a riveted loop fails, it usually tears through the material around the rivet rather than breaking the rivet. A stitched loop can be stitched again. A torn one has lost material.
Why coat and fastenings want opposites
Dense wool cloth is a forgiving material in the right wash. It tolerates cool water and gentle handling, and the thing it will not tolerate is warmth plus agitation together, which makes it felt and draw in. So the sensible treatment for the body of a heavy coat is cool, slow and brief, with as little mechanical action as the soil level allows.
The fastenings want cool and slow as well, but they also want short. Every extra turn of a wet drum is another swelling cycle for a wooden barrel, another flex of a soaked leather loop, and another chance for a barrel to swing against the drum and crack where it is drilled. Time in water is the variable that matters most to them, far more than temperature.
What follows from that is simple and mostly mechanical. Fasten every toggle before the coat goes anywhere near water, so the loops are held and the barrels cannot swing. If the barrels are the kind that are tied on through a knot rather than stitched, they come off first. If they are stitched in place, accept that the fastenings are the part of the coat being spent.
Afterwards, the three places worth looking at are the stitch line where each tab meets the cloth, the holes through each barrel, and the fold in each leather loop. A cut thread, a hairline from a hole, or a crease going pale on the outside of a bend are all early stages of the same failures. Seeing them early is the whole benefit of knowing how the parts behave.
Coats and storage in Jacksonville
A heavy coat spends three seasons of the year in storage in Jacksonville, and storage here means warm air carrying plenty of moisture. Wood and horn both take up moisture from the air around them, so a barrel that has been in a closet all year is not dry in the way a piece of furniture indoors is dry. It has reached a balance with humid air.
That changes how it answers a wash. A piece already carrying moisture swells less in water but dries less evenly, and it takes longer to settle afterward. The practical upshot is that a coat brought out of storage here is better left to sit indoors for a while before being washed, so the fastenings and the cloth start from the same place.
WaveMAX Jacksonville is at 929 McDuff Ave S, easy to reach from Jacksonville and the surrounding area. A heavy wool coat is a load of its own, and the main thing it needs is a drum large enough that the garment turns over gently instead of being packed against the wall with its fastenings pressed into the cloth.
One coat, one load
A dense wool coat soaked through weighs far more than it looks like it should, and a crowded drum cannot turn it. That matters here for an unusual reason: the gentler the tumble, the less the barrels knock about and the less the loops are flexed while they are wet and soft. Space is the setting that counts.
The machines at our self-service laundry on McDuff Avenue South give a heavy coat a drum of its own, which keeps the tumble gentle and keeps wooden barrels from knocking against the wall of the machine while they are swollen with water and at their most likely to split.
Our machines and the store are cleaned daily.

The short version
The fastenings on a heavy coat are usually three materials at once, and each answers water differently. Wood swells more across the grain than along it, so repeated wetting and warm drying splits it from the drilled holes outward. Horn is a protein and softens, dulls or delaminates much as wool does. Leather loops shrink and stiffen when they dry warm, then crack at the fold. Fasten everything before a wash, keep the time in water short, and check the stitch lines afterward.
