What does cotting mean?
Cotting is a specialised term from the textile industry referring to the troublesome build-up of fibres around the cots — the resilient-covered rollers — of spinning and drafting machinery. As fibres pass through the rollers during spinning, they can adhere to and wind around the roller surfaces, forming accumulations that disturb the even drafting of the yarn, produce faults in the thread, and force costly stoppages for cleaning. The problem is influenced by factors such as humidity, roller condition, and fibre type, so mill technicians manage it through careful climate control and regular maintenance of the roller coverings. Because it belongs almost entirely to the vocabulary of spinners and mill engineers, cotting is virtually unknown outside technical circles, yet within its field it names a familiar and persistent operational nuisance. Its similarity in sound to everyday words like 'coating' and 'clotting' can easily mislead readers who meet it out of context.
nounIn textile spinning, cotting is the undesirable build-up and winding of fibres around the cots (the covered rollers) of a spinning frame, which impairs the drafting process.
- The build-up and winding of fibres around the cots (covered rollers) of a spinning frame, causing faults in yarn production.
"The mill technician stopped the frame to clear the heavy cotting that had formed on the top rollers."
"Excessive humidity in the card room led to severe cotting on the drawing-frame rollers."
"Regular grinding and buffing of the cots helps prevent cotting during long spinning runs."
In a cotton mill, 'cotting' isn't about beds or cottages — it's what happens when stray fibres strangle your spinning rollers and grind production to a halt.

Etymology of cotting
The term derives from 'cot', the word for the covered roller used in spinning machinery, with 'cotting' functioning as a verbal-noun form describing the fouling of those rollers. The ultimate origin of the mechanical sense of 'cot' is uncertain, and no reliable account of the term's first recorded use can be given; it emerged within British and American textile engineering vocabulary.
How cotting is actually used
Cotting is a specialised term used mainly within the textile industry, particularly among spinners and mill engineers; it is rare outside technical contexts and would be unfamiliar to most general readers.
Easily confused with cotting
Clotting is the coagulation of blood or liquid into a thickened mass, whereas cotting is a technical term for fibre accumulating on the rollers of spinning machinery.
Coating means covering a surface with a layer of material, while cotting refers specifically to fibres fouling textile rollers.
