The most popular fiber in the world

Cotton is a seed fiber grown as a protective case around the seed of the cotton plant. Known to be the most popular natural fiber in the world, it is soft and fluffy to the touch and is usually off-white in color.



What Is Milk Cotton Fabric?

Milk cotton is a type of fabric that is made with the casein powder found in milk. This type of fabric is also called milk fiber or casein fiber, and it has historically been mixed with a number of substances to provide them with a cotton-like texture and tensility.

These days, most casein fiber is mixed with acrylonitrile, which is the same substance that’s used to make acrylic clothing. Therefore, milk cotton isn’t a truly organic fiber, and it is generally considered to be synthetic or semi-synthetic.

Interestingly, a German fashion designer named Anke Domaske claims to have created a form of milk cotton made from only casein fiber, which means that the fabric she produces can be considered to be entirely organic. Domaske’s company is called Qmilk, and she claims that she had the idea to develop a synthetic-free version of casein fabric after a family member became allergic to most types of clothing upon developing a certain type of cancer.

Intrigued by the potential of milk fiber but discouraged by the manufacturing process currently used to make this fabric, Domaske developed her own method of creating casein fabric without using any toxic chemicals. She claims to make all of her Qmilk garments from waste milk generated by German dairies that can’t be consumed by humans.

Milk Cotton Fabric Used

Milk cotton has primarily been used as an alternative to cotton or silk. While it’s sometimes possible to find apparel that is made entirely from this casein-based textile, it’s much more common to find milk fiber blended into other fabrics. For instance, it may be combined with silk or cotton to create a smoother texture or reduce costs.

Sustainable Options

Casein fiber is sometimes used for home textiles such as towels and bed sheets, but its primary application is as a material for apparel. As casein fiber made from pure milk with no added synthetic ingredients becomes more and more popular, this type of textile is carving out a market niche for distinct groups of consumers.


Milk cotton made with acrylonitrile is marginally better for textile workers and the environment, but the production of this subtype of casein fiber still can’t be considered to be truly sustainable. It is practically impossible to recycle acrylic textiles, and these fabrics do not decompose. In addition, most kinds of acrylic fabric are highly flammable, which poses another health hazard.
