What Is Silk Fabric?

Silk is the strongest natural textile in the world. This textile was just recently surpassed in strength by alab-engineered biomaterial, but it remains the strongest fabric made through natural processes.

Despite its immense tensile strength, silk is generally prized for other reasons. Silk's softness has made it a hotly desired commodity throughout history, and this simple fiber has built legendary trade routes and transformed cultures throughout the Old World.

Comprised of a natural protein fiber, silk mainly consists of fibroin, which is a protein that certain types of insect larvae secrete to make cocoons. While other insects also produce silk-like substances, most of the world's silk is derived from Bombyx mori larvae, which are worms that only live on mulberry trees.

In certain lighting conditions, silk produces a shimmering optical effect, which is due to the triangular prism-like structure of silk fibers. These prisms reflect light at various angles, which results in the subtle rainbow hue that has made silk so famous.

Originally, human beings harvested wild silk to make rudimentary fabrics. While worms spin silk in the wild in parts of China, India, and Europe, wild silk is never available in large enough quantities to satisfy the needs of full-blown textile production.

Cultivation of domesticated silk originated in China. One piece of archaeological evidence dates the use of silk textiles in China back to 6500 BC, and the ancient Chinese certainly used silk as early as 3600 BC.

While historical records of the origin of silk manufacturing in China are largely lacking, Chinese legends credit Empress Leizu with the development of sericulture, which is the art of making silk. In the early days of Chinese culture, only the nobility wore silk, but as Chinese civilization developed and became wealthier, commoners started wearing this soft and durable fabric as well.

Silk production in China eventually led to the development of prominent pre-industrial trade routes. The Silk Road stretched from China to Western Europe, and Chinese merchants traveled up and down this trade route to exchange silk for the commodities of distant nations.

For generations, the secrets of sericulture were the most prized and guarded pieces of knowledge of the Chinese nobility, but eventually, information on how to make refined silk spread to Korea and India during the first few centuries AD. India, Thailand, and other Asian nations already had highly-developed sericulture processes at this point, but the Chinese method of making silk was considered to be superior.

Based on limited legends and historical records, silk may have also been produced in the West during the distant past. Whatever the case may be, silk was highly prized by Westerners as far back as Roman times, and the popularity of this rare and mysterious substance only grew during the Medieval period.

By the 11th century AD, silk production was widespread throughout Europe. Many Italian city-states, such as Lucca, Venice, and Florence, were highly economically reliant on silk production during the Middle Ages, and the silk industry gradually spread to France and Spain.

King James I introduced silk production to the New World in the 17th century, and American states such as Connecticut and Massachusetts rapidly became hubs of silk production. World War II cut America off from Asian silk, and as a result, American corporations developed synthetic replacements such as nylon.

How Is Silk Fabric Made?

While the silk industry has expanded greatly during the last century, the processes used to make this fabric are still largely the same as they were in the ancient world.

Once silkworm breeders have harvested silkworm cocoons, they usually expose them to high heat to prevent the mature worms from emerging. Some animal rights activists protest this practice; they contend that it's possible to harvest silk without killing silkworms, but not much credence is given to this position.

After the cocoons have been heated, silk producers carefully unravel the threads that the silkworms meticulously put into place. To do so, the silk cocoons may be boiled briefly to remove a small amount of the sericin in the cocoons, which is the glue-like substance that silkworms excrete to form their metamorphosis chambers.

Silkworms make cocoons out of one long strand of fiber, which means that a fully unraveled cocoon results in a single string of silk. To unravel a cocoon, a silk worker or an automated machine will brush the cocoon to find the loose end and load it through a porcelain eyelet onto a reel that unravels silk strand.

'/>Bow-tie Neck Silk Blouse

As the silk strand loads onto the reel, it is automatically attached to another strand to make a continuous string. The sericin in the silk strand helps the strands stick together. Next, silk producers twist these long strings together to make yarn.

Silk producers may perform a variety of post-production processes to create silk yarn that has certain desired attributes, and then the silk yarn is put through a roller to make it more uniform. At this point, the yarn is ready to be woven into a garment or another type of textile.

Before they weave it, most silk textile manufacturers dye their yarn, and they may bleach it. These manufacturers may also stiffen or steam silk to achieve desired attributes.

How Is Silk Fabric Used?

'/>

Silk can be used in thousands of different ways. For our purposes, however, we'll separate the potential purposes of this fabric into consumer and industrial categories:

Consumer

The most common consumer application of silk is apparel production. Silk has been prized for thousands of years for its incredible softness and durability, and to this day, consumers prefer real silk over its synthetic alternatives.

Examples of consumer apparel items made from silk include scarves, shirts, blouses, and eveningwear. Due to its lightweight and soft attributes, silk is also a favorite material for lingerie and underwear for men. In the home, silk might be used to make decorative pillows, curtains, or wall hangings.

Industrial

Even though there are synthetic alternatives for this application, many parachute manufacturers still make their products with silk due to this material's durable and lightweight applications. In addition, medical practitioners and surgeons use silk surgical sutures to close wounds and surgical openings. This fiber is very thin, and it has antibacterial attributes, which makes it ideal for this application.

Where Is Silk Fabric Produced?

'/>

According to World Atlas, China holds a dominant position as the world's largest silk manufacturer. At 146,000 metric tonnes of silk per year, this East Asian nation vastly outstrips its largest competitor, India, which only produces 28,708 metric tonnes of silk every year.

Uzbekistan comes in at third place, and Thailand is fourth in silk production worldwide. China is the world's largest silk market as well as the largest producer of this textile, and the United States and European Union also consume a lot of the silk produced in India and China.

How Much Does Silk Fabric Cost?

The site EmergingTextiles.com releases quarterly reports indicating the current prices of silk in China. According to the latest report, Chinese silk currently ranges between $50 and $55 per kilogram. The Indian government also keeps track of the prices of silk produced in this nation.

There's no getting around the fact that silk fabric is expensive. This type of fabric is hard to produce, and due to shipping costs, it is expensive to move silk from its point of origin to the end consumer. Keep in mind, however, that a kilogram of raw silk can go a long way when you're producing garments.

What Different Types of Silk Fabric Are There?

'/>

While mulberry silk is, by far, the most widely produced type of this fabric, there are a few other types of silk fabric worth mentioning as well:

1. Mulberry Silk

Mulberry is the easiest and least expensive type of silk fabric to make. Almost all the silk in the world is mulberry silk, and like other types of this textile, mulberry silk fabric is renowned for its strength, softness, and durability.

2. Eri Silk

Since the production of eri silk fabric doesn't require killing silkworms, this textile variety is also called 'peace silk.' While hardly any eri silk is made throughout the world, this fabric is heavy and even more durable than mulberry silk. Since eri silkworms live on castor trees, this type of silk is sometimes known as 'castor silk.'

3. Tasar Silk

Next to mulberry silk, tasar silk is the second-most produced type of silk fabric. This variety of silk is wild, and it is produced by silkworms native to India. Japan is also home to tasar silkworms, but the silk these worms produce is green.

4. Spider Silk

Certain types of spider silk are highly tensile, but spiders can't be bred like silkworms. Therefore, spider silk is extremely expensive to produce, which makes it invalid for textile production. Instead, producers use spider silk to make bulletproof vests, microscopes, telescopes, and other industrial or niche products.

5. Muga Silk

Muga silk fabric is only produced in the state of Assam in India, and muga silkworms are semi-domesticated. While muga silk isn't widely known in the rest of the world, generations of Assam residents have made muga silk garments for the nobility of this region.

6. Sea Silk

A certain species of mussel native to the Mediterranean Sea produces small quantities of a silk-like fiber. Residents of Taranto, Italy have domesticated these mussels, and this town produces small quantities of sea silk fabric, which is also called 'mussel silk.'

7. Coan Silk

A species of silkworm called Pacypasa atus produces coan silk, which is native to certain parts of Greece, Turkey, and Italy. These silkworms feed on pine, juniper, and oak trees, and while coan silk was widely used in Ancient Rome, coan silk fabric production today is limited, and this type of silk is mainly used to strengthen other types of silk fibers.

How Does Silk Fabric Impact the Environment?

Since silk is a natural fiber, it is inherently sustainable and non-damaging to the environment. The harvesting and production of wild silk does not have any negative environmental impact, but cultivating silk and transporting it around the world may harm the environment in a variety of ways.

'/>Retro Style Silk Blouse

Animal rights organizations, such as PETA, protest silk production because silkworms are killed in the process. However, silk production remains one of the cleanest textile industries; mulberry trees do not require fertilizers or pesticides, which means it's possible to harvest cultivated silk without introducing any toxic chemicals into the environment.

Over the years, silk moths have mutated due to domestication. Mature moths are no longer able to eat due to underdeveloped mandibles, and they are blind. They only live long enough to lay approximately 500 eggs on the leaves of nearby mulberry leaves.

Concerns for silkworms and silk moths aside, silk production in countries like China and India often involves worker exploitation. While automation has made silk production easier and fairer for workers in every part of the world, not all production facilities have access to the same forms of automation.

Since most areas of the world don't produce much silk, it's necessary to ship this substance long distances to reach its final destination. Therefore, fossil fuels are expended in the process of shipping silk. Despite these minor concerns, silk production does not significantly harm the environment, and since silk is 100 percent biodegradable, it does not contribute significantly to pollution.

Silk Fabric Certifications Available

'/>

There are a variety of silk certifications that manufacturers of this textile can use to express the value of their products to customers.Silk Mark certifies Indian textiles, and if a silk garment or another silk product features the Silk Mark logo, it has been judged as being compliant with the strict standards that this organization demands.

Even though silk production is extremely limited in the United States, it's possible to have American silk certified by the United States Department of Agriculture (USDA). In addition, the European Union's organic certification body can certify silk grown within this bloc of European countries as being cultivated with organic or sustainable processes.

Most consumers, however, look for the logo of the Global Organic Textile Standard (GOTS) to determine whether a silk garment is up to snuff. The majority of silk is produced in China, but this country doesn't impose any meaningful regulation on its silk producers. Instead, it's up to organizations like GOTS to inform consumers about the organic status of the silk they're purchasing.

Textile Milk Cotton Yarn

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.

Milk Cotton Bodysuits

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 Yarn

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.

New Knitting wool soft milk Cotton Hand-woven Crochet Chunky Yarn

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.

Aisuru Club X Uglee Milk Cotton Crop Top

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.

What Is Milk Silk Fabric

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?

Is Milk Silk Material Stretchy

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.

Cotton sleeves - Milk silk body

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

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.
