A throw spends this part of the year on the back of a sofa or over the arm of a chair, which is exactly what it is for. It also spends it being sat on, pulled around and dragged across the floor, so at some point it has to be washed. The cloth itself usually survives that without complaint. The decorative edge does not. It comes out matted into ropes, knotted into itself, or noticeably shorter on one side than the other, and none of that is the detergent’s fault.
What a fringe actually is
A fringe on a throw is a row of loose yarn ends hanging off a finished edge. Sometimes those ends are the warp threads of the cloth itself, left long instead of being hemmed, which is how a woven throw with a self fringe is made. Sometimes the fringe is a separate trim mounted on a tape and stitched along the edge afterward.
Those two constructions behave differently from the first wash onward. A self fringe is continuous with the cloth, so it cannot pull out, but any damage to it travels straight into the weave. An applied fringe is anchored only by the stitching holding its tape, so it can come away as a whole strip while the cloth stays untouched.
A tassel is a different object again: a bundle of yarn bound at the top and hanging free below, often with a decorative head over the binding. It is much heavier than a fringe of the same length, because all that yarn is concentrated into one point of attachment rather than spread evenly along an edge.
The yarn is usually not the same as the yarn in the body of the throw either. Fringe yarn is often more tightly twisted, to make it hang straight, or loosely spun and fluffy, to make it look soft. Either choice changes how it takes up water and how it behaves when it is rubbed, and neither one matches the cloth it is attached to.
Tangling is mechanical, not chemical
The reason a fringe knots in a wash has nothing to do with what is in the water. It is a bundle of long flexible strands, free at one end, being moved through a confined space by a rotating drum. Strands in that situation cross each other constantly, and once two strands have crossed, the same motion that crossed them can cross them again.
Each crossing is a half knot waiting to be pulled tight. The drum supplies the tightening by dragging the cloth one way while friction holds the strands the other way. Nothing ever unties anything, because the motion is random and a tightened crossing is more stable than a loose one. Tangling only runs in one direction.
Matting is the same mechanism taken further. Where the yarn is wool, or anything with surface scale to it, the fibers on one strand catch on the fibers of the next, and heat and agitation press them into each other until they interlock. The strands stop being separate strands and become a single felted mass, with no route back to individual yarns.
This is why gentle detergent, cool water and a short cycle all help less than people expect them to. They reduce the chemistry and the heat, which does matter for felting, but they do not reduce the tumbling, and tumbling is what makes the knots. The only real lever available is stopping the strands from moving independently of each other.
A knot is the only thing holding it
A great deal of the fringe on a throw is knotted, either in a simple row of overhand knots along the edge or in a macrame pattern that builds a decorative band before the strands hang free. In both cases the knot is doing all of the work. There is no stitching below it, no tape, and nothing else to take the load if it slips.
A knot grips by friction, with the strands pressing against each other. Soak it and two things change at once. The yarn swells, which tightens the knot, and the yarn surface becomes more slippery, which loosens it. Which effect wins depends on the fiber and the twist, and that is why two similar throws can come out of the same wash in different conditions.
When a knot does slip, the failure runs from the end inward. The strand pulls through, the knot opens, and the strands above it are left loose, so the next wash has more free length to work with than the last one had. Each cycle undoes a little more than the one before, which is why unraveling always seems to accelerate.
Retying is genuinely possible and worth doing early. One knot replaced while its neighbors are still tight keeps the whole row even. A dozen loose knots later, the strands are all different lengths, some have pulled out of the row entirely, and matching the original spacing by eye has become a job rather than a moment’s work.
Why a wet tassel pulls on the cloth
Dry yarn weighs very little. Wet yarn weighs a surprising amount, because the fiber absorbs some water and the spaces between the filaments hold a good deal more by capillary action. A thick tassel can come out of a wash at several times its dry weight, and all of that weight is hanging from one small point of attachment.
That point is a few stitches through the cloth at the corner or along the edge of the throw, and those stitches now have to carry a swinging weight through an entire spin. The force is not steady either. It rises and falls as the drum turns, and repeated loading of that kind is exactly what works stitching loose over time.
What shows afterward is a puckered corner, or a small distortion in the weave where the tassel hangs, or in the worst case a pulled hole with threads running from it. The tassel itself may be in perfect condition. The damage is to the cloth that was asked to carry it while it was heavy.
Heavier yarn also dries far more slowly than the throw does, for the same reason that it holds more water. A bound bundle has a dense core with no airflow reaching it, so the body of the throw finishes long before the trim does. A throw folded away at that point has a damp spot in every corner where a tassel sits.
Braiding and bagging before a wash
Two things actually work, and both are about preventing independent movement rather than about the wash itself. The first is braiding. Gather the strands along each edge into loose plaits, three or four to an edge, and secure the end of each one with a soft tie. Braided strands cannot cross each other, so they cannot knot.
The second is containment. A fringe tucked inside a mesh bag, or the whole trim rolled in toward the middle of the throw and the roll tied loosely with a length of cotton tape, keeps the strands away from other items and away from the drum wall. Most tangling involves something other than the fringe, so removing the contact removes the problem.
For tassels, the useful move is to support the weight rather than let it hang. Rolling the corners inward and tying the roll means each tassel travels inside the bundle instead of swinging from a few stitches, which removes the loading that distorts the cloth at the point of attachment.
Drying is the last step and the one most often skipped. Lay the throw out flat, comb the strands straight with your fingers while they are still damp, and leave them separated from each other. Yarn dries in whatever shape it is left in, so straight damp strands dry straight and bunched damp strands dry bunched into exactly that shape.
Throws in Fort Worth homes
Fort Worth gets dust on the wind and heat for a long stretch of the year, and a throw that lives on a sofa picks up both of them. The body of the cloth takes that fairly evenly. The strands along the edge take more, because they hang down into the moving air and touch the floor, the furniture and whatever brushes past them.
This is the season when throws come out of storage and into daily use, which means a wash is coming whether it was planned or not. A throw that was folded away with a tangled or matted edge has had that edge compressed in a box for a long stretch, and compressed matting is considerably harder to open out than fresh tangling is.
WaveMAX Fort Worth is on Meadowbrook Drive, and a throw is a good example of something that does better in a drum with room to spare in it. Trimmed items need to move freely rather than be packed in, because a packed load holds the strands against the drum wall and against each other for the whole cycle.
Throws and blankets with trim
A throw washes best with room around it and nothing abrasive in the load beside it. Larger drums let a big piece of cloth open out and turn over instead of balling up, which keeps the trim off the wall of the drum, and a low heat setting keeps wool from felting along the edges while it dries.
The machines at our self-service laundry on Meadowbrook Drive give a trimmed throw the room it needs, with a drum big enough for a large piece of cloth to turn over freely and a low heat setting for the drying, which between them is most of what keeps an edge from matting into ropes.
Our machines and the store are cleaned daily.
Our wash-dry-fold service covers the everyday laundry.

The short version
A fringe is a row of long free strands, so a turning drum crosses them and then tightens the crossings. That is mechanics rather than chemistry, and a gentler detergent does not help. Knotted fringe is held by the knot alone, so it unravels from the end once a knot slips. A wet tassel weighs many times its dry weight and hangs from a few stitches. Braid or bag the edge first.
