What does azlon mean?
Azlon is the generic name for a class of manufactured textile fibres produced from regenerated natural proteins. Unlike fully synthetic fibres such as nylon, which are built from petrochemicals, azlons begin with proteins extracted from renewable sources — most famously casein from skimmed milk, but also soybeans, peanuts, and zein from maize. These proteins are dissolved chemically and forced through spinnerets to create filaments that can be spun into yarn, often blended with wool to reduce cost or stretch limited supplies. The term was adopted by the British textile industry in the late 1930s, drawing on 'azote', an old French name for nitrogen, reflecting the protein origin of the fibres. Azlon reached its peak of importance during and shortly after the Second World War, when natural fibres were scarce. Though largely a historical curiosity today, the word remains significant in textile science and in accounts of how industry responded to material shortages.
nounA manufactured textile fibre made from regenerated natural protein, such as casein (from milk), soybean, peanut, or zein (from maize) protein.
- A manufactured fibre composed of regenerated natural protein (casein, soy, peanut, zein, or similar), used as a wool substitute in textiles.
"During the wartime wool shortage, mills turned to azlon fibres spun from casein to stretch scarce supplies."
"The sweater's label listed azlon alongside wool, marking it as one of the early protein-based fibres."
"Textile historians regard azlon as an intriguing footnote in the search for alternatives to natural animal fibres."
Usually a mass noun referring to the fibre material; the plural is used mainly when distinguishing among different protein-fibre types.
"Early azlons varied considerably in strength depending on the source protein."
In the 1930s and 1940s, scientists literally spun clothing out of milk — and the resulting protein fibre got its own official name: azlon.

Etymology of azlon
The word azlon was coined in Britain in the late 1930s as a generic term for man-made fibres derived from regenerated natural proteins. It combines 'azote', the French name for nitrogen adopted from Greek roots meaning 'without life' (a name originally applied to nitrogen gas), with the suffix '-on'. Its coinage reflected the era's drive to classify new protein-based fibres alongside emerging synthetics like nylon.
How azlon is actually used
Azlon is a technical term used mainly in the textile industry and in histories of fibre science; it is rare in everyday speech. It functions as a mass noun when referring to the fibre material generally, though plural 'azlons' can refer to distinct types of protein fibre. The term is now largely historical, since most protein-based fibres were commercially unsuccessful.
Easily confused with azlon
Nylon is a fully synthetic polyamide fibre made from petrochemicals, whereas azlon is a semi-synthetic fibre regenerated from natural proteins such as milk casein or soy.
