Textile Milk Cotton Yarn
What Is Milk Cotton Fabric?
- Cotton yarn can be woven or knitted into fabric. While weaving, users can interlace the yarns to make a solid, sturdy cloth. It can be done by hand or with a machine. Silk, a type of protein fiber, woven from materials created by insects like silkworm, caterpillars, bees and wasps, is made from the cocoons of the.

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.
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.
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.

At this point, the production of milk cotton worldwide is very minimal. While this fabric experienced its heyday in the early decades of the 20th century, it fell into obscurity as other synthetic or semi-synthetic fabrics became cheaper and more prevalent. While milk cotton made with acrylonitrile is unlikely to make any gains in popularity, it's possible that pure casein fabric will become more popular as time goes by due to its unique allergen profile and the environmentally sustainable production processes that are used to make this textile. Across the world, textile producers are focusing on the potential that protein-based fibers have to solve the environmental issues associated with producing cotton and other staple textile crops.
Consumers prize milk cotton for its softness and smoothness, and it is often used for apparel products that are worn close to the skin. However, it is relatively difficult to produce casein fiber, which means that most consumers are unlikely to have experienced the benefits of this fabric. Those who have worn milk cotton report that it has very pronounced moisture wicking abilities, and pure forms of casein fabric can be washed at high temperatures. Since they contain acrylic, however, semi-synthetic forms of this fabric can only be washed in cold or warm water.
How Is Milk Cotton Fabric Made?
The process used to produce this type of fabric depends on the version of casein fiber that is being made. However, no matter which subtype of casein fabric is produced, the first step in making this textile is obtaining milk.
In most cases, the milk used to make milk cotton is waste milk that is otherwise unusable. This product is generally obtained directly from a dairy, and it is then skimmed to remove fat and dewatered. The end result is similar in appearance to milk-based protein powder, but to make fabric, the casein protein still needs to be extracted from this powdered substance.
The powdered milk is then dissolved and purified to remove any substances that are not casein. Past this point, however, the production process diverges based on the methods that are being used.

The original production process for casein fabric entails the immersion of powdered casein in alkali to make a solution that is then passed through a spinneret. After it has made its way through the spinneret, the solution is immersed in sulfuric acid to remove the alkali. The resulting fibers are then stretched and spun into yarn, and they are tanned with aluminum salts and formaldehyde to render them into usable textile yarn.
It's easy to see the problems with this production method. Formaldehyde is toxic, and a variety of other chemicals are also used in this process that may also be harmful to workers, the environment, or the end consumer.
The modern method of producing casein fiber involves chemically grafting pure casein to acrylonitrile in a process called graft copolymerization. This process doesn't entail the use of formaldehyde or any of the toxic chemicals that were used in the original casein fiber production method, but acrylonitrile is also a known toxin and carcinogen. While this modern method is more efficient and potentially safer, it still has its fair share of problems.
Recently, a variety of milk cotton producers have reported their newfound capacity to manufacture stable and tensile forms of this textile without mixing it with any synthetic materials. Ostensibly, this new production method is much more environmentally-friendly and results in a safer workplace, but there's just one catch: There's no detailed information available that explains the exact nature of the processes used to make this sustainable form of casein fabric.
For instance, the makers of Qmilk claim that their production process produces zero waste and that their fabrics are entirely biodegradable. However, they do not indicate which methods they use to avoid the necessity of including acrylonitrile or formaldehyde in the production process.
As casein fabric becomes more popular, it's likely that scholarly articles and other sources of information will appear with more details on how these new fully-organic versions of milk cotton are made. At this point, it's necessary to simply trust that manufacturers like Qmilk are living up to their promises.
How Is Milk Cotton Fabric Used?
Due to its glossy and rich texture, casein fabric has been widely used as an alternative to silk since its invention. While this fabric is inferior to real silk, it can replicate the lightness and softness of this textile if it is manufactured properly.
One of the main purposes of milk cotton in the 1930s and 1940s, however, was as a replacement for wool for members of the military. It was quickly determined, however, that milk fiber products, which were branded as Lanatitil, Merinova, and Aralac, were inferior to wool, and production of these fabrics ceased as purely synthetic materials, such as nylon, became increasingly popular in the post-war period.

In recent decades, 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.
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.
On the one hand, there are consumers who have allergies to other common textiles who seek out pure casein fiber for its unique allergen profile and generally mild texture. On the other, some consumers prefer pure milk cotton because they perceive that it is made in an environmentally sound manner and that it actually reduces the milk waste that would otherwise be generated by major dairies.
Where Is Milk Cotton Fabric Produced?
No one country is considered to be a major producer of this type of textile because it is not produced in high quantities. As with most types of textiles, China is the single greatest producer of milk cotton, but even within the borders of this manufacturing powerhouse, casein fiber is not produced in any great quantities.
The milk cotton fabric that is produced in China, however, is almost invariably the type that is mixed with acrylonitrile, which means it is environmentally hazardous and harmful to workers. If you want milk cotton that is made from pure milk using environmentally friendly processes, you'll need to work with independent suppliers in Europe and elsewhere who are currently pioneering the renaissance of protein-based, sustainable fibers.
How Much Does Milk Cotton Fabric Cost?
Milk cotton is generally quite costly. The high price of this fabric was the primary factor that originally caused the decline of the casein fiber industry in the mid-1900s, and the cost to produce this textile hasn't reduced significantly despite the development of more efficient manufacturing processes.
Purely organic milk cotton costs significantly more than other types of this fabric. For instance, the fabric that Qmilk uses to make its textile products costs about 40 percent more than cotton, and these high prices will likely continue to disincentivize the popularity of this type of fabric.
What Different Types of Milk Cotton Fabric Are There?
While milk cotton made with formaldehyde is a thing of the past, semi-synthetic milk fiber made with acrylonitrile is the most commonly-produced type of this substance. Another type, however, that is made with pure casein is rapidly becoming the preferred form of milk fiber across the world.
How Does Milk Cotton Fabric Impact the Environment?
The environmental impact of casein fabric varies depending on the type of manufacturing process that is used. For instance, the original forms of milk cotton that were popular in the early 20th century were often processed with formaldehyde, which is a neurotoxin that contaminates the ecosystem. Any milk fabric that is made with formaldehyde is not environmentally sustainable, but it's unlikely that any casein fiber manufacturers continue to use this toxic substance to create their products.
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.

Furthermore, the Centers for Disease Control (CDC) has indicated that acrylonitrate enters the body via skin absorption, inhalation, and ingestion and that this substance is a carcinogen and mutagen. Wearing fabrics made with acrylonitrile may cause cancer, and workers who contact this substance during production may also encounter serious health difficulties.
If the acrylonitrile used in the milk cotton production process is not disposed of properly, it can negatively impact the environment. Also, according to some estimates, it takes about 100 gallons of milk to make three pounds of milk fiber, which means that the casein fiber production process could be wasteful. According to Anke Domaske, however, she can make six T-shirts with one kilogram of milk, which appears to indicate that the amount of milk needed to make this fabric is not standardized.
Until the production of milk cotton becomes more mainstream, it will remain unclear whether or not this substance is good or bad for the environment. On the one hand, it seems that making this substance can put waste milk to good use that would otherwise be thrown away, but on the other, it's clear that certain methods for producing milk cotton are profoundly environmentally hazardous.
Milk Cotton Certifications Available
What Material Is Silk Milk Fabric
In 2004, the entirety of the purely organic milk fiber industry was granted Oeko-Tek Standard 100 certification, which means that it is considered to be 100 percent environmentally sustainable. However, it is again important to stipulate that the largest producers of purely organic milk fiber have yet to disclose details on their production processes, so it's impossible to say exactly which aspects of this industry prompted this coveted certification.
At this point, neither the United States Department of Agriculture or the EU's organic standards organization have recognized milk fiber as a textile that can achieve organic status. As the production of this textile increases in volume and the recipes used to make purely organic casein fiber lose their trade secret value, it's possible that more certifications for this textile will be made available. Needless to say, the semi-synthetic fabric made by mixing casein fiber and acrylonitrile cannot be certified as organic or environmentally sustainable.
A FEW FACTS
- Milk fibre is made from casein, a protein in milk, and is normally blended with the chemical binder acrylonitrile – the main component of acrylic yarn.
- Milk fibres are made from sour, not fresh, milk.
- In Germany around two million tonnes of milk are thrown away each year. Milk fibre dyes and smells like wool.
- A drawback of milk fibre is that it wrinkles easily.
- Milk fibre has a PH similar to human skin, and is antibacterial and antifungal.
- Milk fibres can be used to make all sorts of clothing, including T-Shirts, sportswear, dresses and underwear.
A significant proportion of food waste is dairy. WRAP, a UK charity that helps individuals and organisations reduce waste, says that 20% of the estimated 1.7 million tonnes of annual waste created during food manufacturing in the UK is dairy, second in volume only to meat and fish. It is, however, possible to turn dairy waste into a surprising new material: fibres that can be spun and woven and used to make clothing and other textiles.
Beda Ricklin, CEO of Swicofil, a yarn and fibre company based in Switzerland, which sells milk fibres produced by manufacturers in China, says that milk fibre is “a very smooth and soft product” that is mainly used for clothing worn close to the skin, like socks and underwear.
In the past, Ricklin has had his own milk fibre socks, which were “very nice to wear, like cashmere or silk”. These luxury fibres, he adds, are the best conventional comparisons to milk.
Milk fibre isn’t new. It was being used for clothing and household items during the 1930s and 40s, as a substitute for wool. Later, cheaper synthetics like nylon became more popular.
Milk fibre belongs to a class of bio-based, man-made fibres known as regenerated protein fibres. It is made from the protein casein, which can be separated from sour milk. Casein is dissolved in a solution and then forced through a spinneret – a device that resembles a shower head – to produce long strands, which are then stretched, heated and chemically treated to increase their strength and stability.
In the past, unpleasant chemicals such as formaldehyde were used to strengthen the fibres. Today, most milk fibres are blended with the chemical binder acrylonitrile, which is also the main component of acrylic yarn.
“Formaldehyde is certainly not something you find in milk fibre today” says Ricklin. The fibres sold by Swicofil have been granted the international Oeko-Tex Standard 100 certification, which means they are free of various chemicals that are harmful to humans and the environment.
According to Ricklin, the plus points of the fibre are that it feels very nice, is good at wicking moisture from the body and has great insulation properties, but he adds that it has a limited market due to its cost. For comparison, polyester costs around $1–$2 per kilogramme, while milk fibre is approximately $25–$35, although this is cheaper than other luxury fibres like silk.
In Germany one producer claims to have developed a technique for creating milk fibres that uses only natural ingredients. Microbiologist, fashion designer and founder of Qmilk, Anke Domaske, first became interested in milk fibre when her stepdad developed allergies following a cancer diagnosis and struggled to find clothes he could wear.
Domaske was looking for a chemical and pesticide free fabric. “When I first heard about milk fibre I was very enthusiastic, because it is milk, it is natural and healthy,” she explains. “But when I found out that the manufacturing process uses lots of chemicals I was very disappointed.”
Domaske says that her process creates a fibre that is “so natural you can eat it”. “It is also antibacterial, flame retardant, and temperature regulating”, she adds. And it can be washed at 60°C.
Qmilk’s fibre is produced using waste from German dairies. “In Germany over two million tonnes of milk is wasted every year because it isn’t suitable for human consumption,” says Domaske.
According to Domaske, a kilogramme of milk fibre can make approximately six T-shirts, while two tonnes is enough to make a T-shirt for every person in America – all 323 million of them – although currently she only makes dresses.
Kay Politowicz, co-founder of Textiles Environment Design (TED) at Chelsea College of Arts, in London, says that “new protein fibres are going to be a great addition to the world of sustainability” as they offer “the possibility of a renewable starting and a recyclable end point, for materials that actually feel good and perform in the ways you need”.
She says, however, that there will always be detractors. People who question whether we should be using waste milk and argue that we should not base an industry on waste that should not occur.
But the waste is there. “You can have an idealist target and you can be practical, it is about finding that balance,” explains Politowicz.
According to WRAP, 200,000 tonnes of the 340,000 tonnes of milk wasted during the manufacturing of dairy products in the UK is avoidable. Leaving 140,000 tonnes of waste that may be unavoidable.
