Weight consistency, fuzz, and lint
Three complaints reach a towel supplier more often than any other: it sheds on the client, it feels different from the last order, and the carton weighs less than the paperwork says. The first two are usually described with the same words, and they are not the same fault. This page separates them.
In short
- Fuzz and lint are different. Fuzz is fiber standing up on the surface; lint is fiber or debris leaving the towel.
- Fuzz has two drivers: fiber composition and water-jet entangling. More polyester means more fuzz.
- Higher water pressure entangles the web more and reduces fuzz, but stiffens the cloth and reduces its thickness. The setting is a balance, not a maximum.
- Lint follows the fiber: Polyester > Viscose ≈ Lyocell ≈ Cotton.
- Delivered weight drifts from nominal GSM in two places: web forming (across and along the web) and slitting and rewinding (core versus outer of the same roll).
- In a pearl texture above 80 g/m², a viscose share below about 70% tends to fuzz; above 90 g/m² the practical floor rises to about 80% viscose.

05.1 · Vocabulary
Two words that get used as one
Fuzz
Fiber ends lift from the surface and the cloth looks hairy or rough. The fiber is still attached. A fuzzed towel can still be used; it feels wrong and photographs badly, which is usually why it comes back.
Lint
Fiber or debris leaves the cloth and ends up on skin, on a mirror, or on a dark surface. The fiber is gone. This is the fault that ruins a salon service, because the client sees it before the staff does.
The distinction matters commercially: a buyer who reports "shedding" may be describing either one, and the corrective action is different. A photograph of the towel surface, plus a dark cloth wiped across it, separates the two in about a minute.
05.2 · Fuzz — cause one
Fuzz starts with the fiber
In our own production of viscose / polyester towels, the higher the polyester share, the more readily the surface fuzzes. That is why a blend has to be written with its ratio. "Viscose / Polyester" describes two materials; it does not describe a product, because 70/30 and 80/20 do not behave the same at the same GSM and the same texture.
The practical consequence is a threshold, not a straight line. In a pearl texture:
| GSM | Viscose share below which fuzzing is likely | How to use this |
|---|---|---|
| Above 80 g/m² | About 70% | Write the ratio into the specification and confirm on a sample at the intended GSM |
| Above 90 g/m² | About 80% | The floor rises with weight, so a ratio that passed at 80 g/m² may not pass at 95 g/m² |
These thresholds come from our own pearl-texture production and were approved for publication on 2026-10-13 as an illustration of what we encounter. They are not a standard, not a test result, and not a guarantee for another supplier or another texture. Plain and EF surfaces behave differently.
05.3 · Fuzz — cause two
Fuzz also starts with the water
Spunlace cloth is made by laying fibers into a web and then entangling them with high-pressure water jets, fired from a row of injectors. The more energy the web absorbs, the more the fibers wrap around each other, and the harder it is for an end to lift.
So pressure reduces fuzz. It also does two other things: it stiffens the cloth and it reduces its thickness. Push pressure up to win the fuzz argument and the towel stops feeling like a towel. The setting is therefore a balance across three properties at once — fuzz resistance, hand, and thickness — and the balance point moves with the fiber, the GSM, and the texture.
| Change | Effect reported from our line | What to watch |
|---|---|---|
| Raise pressure | Fiber entanglement increases; the surface fuzzes less | Confirm the hand and thickness still match the approved sample |
| Raise pressure too far | Cloth becomes stiffer and thinner | Thickness is not in the GSM figure, so it has to be checked on the piece |
| Balance fiber and pressure together | Fuzz resistance, hand, and thickness are traded against each other | This is the setting that gets approved, and it is specific to the specification |
No pressure value, thickness change, or stiffness measurement is published here. The direction of each effect is what has been confirmed; the numbers are set per specification and per machine.
05.4 · Lint
Lint follows the fiber
At equal GSM, the tendency for fiber to leave the cloth ranks by fiber rather than by construction: polyester sheds most, and viscose, lyocell, and cotton sit close together at the low end.
| Rank | Fiber | Reading |
|---|---|---|
| Most | Polyester | Sheds most readily of the four |
| ≈ | Viscose · Lyocell · Cotton | Close together, and all substantially lower than polyester |
"Does not shed easily" is not "sheds nothing". No fiber in this range is zero-lint, and a supplier who promises zero has either not measured it or is describing something else. The order above is a qualitative comparison from our own product at equal GSM; no lint count, test method, or threshold is attached to it.
05.5 · Weight
Nominal GSM is not a delivered weight
GSM is measured on a square meter of cloth. A towel is a cut piece of that cloth, so its weight is the GSM times its area — and any variation in the cloth becomes variation in the piece. Two places on the line produce that variation, and they produce it in different directions.
Web forming
Fiber is laid into a web before bonding. The lay-up is not perfectly even, so weight varies across the width and along the length of the web. A piece cut from one edge and a piece cut from the middle can differ even when both are nominally the same size.
Slitting and rewinding
When the bonded cloth is slit and wound, tension and compression differ between the core of the roll and its outer layers. Thickness — and with it the weight of a fixed-area piece — can differ between the start and the end of the same roll.
The visible result is a small number of packs whose piece weight, or whose packed height, falls outside the agreed figure. It is a tail-end problem, not a systemic one, which is exactly why it survives a casual inspection: the first ten pieces from a carton can be perfect and the eleventh is not.
Three things that control it
Batch consistency. The lot is controlled to the approved specification, not left to drift. This is a controllable commitment rather than an assumption that cloth is uniform.
The CV value. The coefficient of variation makes the spread visible. A mean piece weight on target with a wide CV is a worse product than the same mean with a tight one, and only the CV shows the difference.
Rewinding unevenness. Watching the core-to-outer difference in the same roll catches the drift that cross-web measurement misses.
05.6 · Specification
What to write into the specification
Five lines that prevent most disputes
- The material with its ratio, for example 80% viscose / 20% polyester — not the fiber names alone.
- The nominal GSM, and a piece weight tolerance expressed in grams per piece.
- The texture, named against an approved reference sample.
- The acceptance rule for fuzz and lint — how it will be judged, on what surface, by whom.
- The packed height or pack weight tolerance, if the pack has to sit in a dispenser, a shelf, or a fixed carton.
A specification that names only the material and the size leaves both defect questions and the weight question open, and they will be reopened at the first complaint.
05.7 · Limits
What this page does not claim
No test numbers
Nothing here is a laboratory result. No absorbency rate, wet strength, lint count, or pressure value is reported, because none was measured for this page.
No comparison with other suppliers
These observations describe our own line. They are not a statement about how another factory runs, and should not be read as one.
No zero-defect promise
Fuzz, lint, and weight variation are controlled, not eliminated. Any supplier offering zero on all three is describing something other than a manufactured textile.
No fixed process recipe
Pressure, fiber ratio, and bonding settings are chosen per specification. The directions above hold; the numbers do not transfer from one product to another.
