The history of milk protein fabric: why milk underwear is nothing new
Share
Many people think that underwear made from milk protein is a complete novelty. But the truth is different. This material appeared in the 1930s. Today we are returning to it in the form of the innovation Milk Skin from Maryl .
Milk protein substance and its origins
Scientists had already discovered in 1935 that casein, the main protein in milk, could be used to make a silk-like fiber. In Italy, it was called Lanital , in Germany, Aralac . The milk-based material was soft, breathable, and had natural antibacterial properties.
Back then, the focus wasn't on eco-friendly clothing or sustainable underwear . The goal was to find a replacement for expensive and scarce fibers like wool or silk.
Use during World War II
During the war, milk fiber came to the fore. It was cheaper, more accessible, and used surplus milk that would otherwise have ended up as waste.
👉 Benefits of using it:
silk-like softness,
hypoallergenic underwear suitable for sensitive skin,
antibacterial effects,
waste utilization and saving natural resources.
From today's perspective, it sounds like the definition of circular fashion, only back then it was mainly about survival.
Why milk fiber has been forgotten
After the war, synthetic fibers like nylon and polyester boomed. They were cheap, widely available, and easy to maintain. Natural fibers like milk protein material took a back seat.
Return to sustainable fashion
Today, the substance from milk is making a comeback, this time in a more ecological and innovative form. Modern production uses milk protein from waste milk and gentle processes without chemicals and with low water consumption.
