What Is Rayon Fabric and Is It Sustainable?

What should our approach be to rayon? Is it the latest trend, or is it something we should avoid in our sustainable fashion collections?

Semi-synthetic viscose fabric, also known as viscose, is often hailed as eco-friendly. It is also the world’s third most popular textile fiber, after cotton and polyester. Do you think this is a good thing?

How does rayon fabric compare with hemp, cork, wool, and cashmere? But what about rayon’s eco-friendliness?

Throughout this article, we at SewingWithEase have explored the ins and outs of cellulosic fabrics and how some brands may not be as authentic as they claim.

Key Takeaways

  • Rayon, a hybrid textile, skillfully imitates organic fibers such as silk and cotton yet necessitates an intricate, chemical-reliant creation method.
  • This fabric’s manufacturing might exacerbate air and aquatic contamination, prompting deforestation.
  • Although it emerges from natural sources, the biodegradability of rayon suffers due to lingering chemicals under landfill scenarios.
  • Esteemed for its adaptability, comfort, graceful draping, vivid color preservation, and economic value, rayon stands out.
  • In contrast to cotton, it is less durable, requires more meticulous care, and is more damaging to the environment.

What Is Rayon Made Of?

Cellulose is the main ingredient in rayon. A variety of plants produce cellulose from their fibers. You can get rayon from one type of plant or a mixture of plants and other materials. The following plants are used to make rayon:

  • Bamboo
  • Wood pulp
  • Agricultural byproducts
  • Cotton waste
  • Oranges

How is Rayon Made?

Each type of rayon is made using a slightly different process. However, here are some basic guidelines.

The plant fiber is first turned into pulp by rayon manufacturers. In the next step, cellulose solution is formed by treating the pulp with chemicals. This dense material is then extruded into fibers through a spinneret. A chemical bath follows the extrusion of the fibers.

Finally, rayon cloth is woven from the fibers spun into thread.

Different Kinds of Rayon

What Is Rayon Fabric and Is It Sustainable?

It is possible to find rayon in several different types.

The viscose process is used to manufacture viscose. Wood and bamboo are most commonly used as fibers for viscose rayon, used to make various products, including clothing, industry, and cosmetics.

Reconstituted cellulose is used to manufacture Modal. Fabrics with Spandex or cotton usually contain this material. Clothing is the most common application for Modal.

Dry jet-wet spinning is the process used to make Lyocell. Primarily, it is used in clothing as a replacement for cotton. There are also some types of medical dressings, conveyor belts, and papers that contain them. A large amount of bamboo is used in Lyocell, but it is not the only source.

There are different types of Lyocell, including TENCEL™.

In the production of Cupro (also known as Bemberg), copper is combined with ammonia for a crystalline structure.

Lyocell and modal rayon

Lenzing has led the responsible production of rayon.

A sustainable beech tree makes TENCEL™ modal, and eucalyptus trees are used to make TENCEL™ lyocell.

Those names are probably familiar to regular readers of Sustainable Jungle, but you might not be aware that they are technically rayons. The main difference is that lyocell fibers are spun using solvents, which do not undergo significant chemical changes.

Despite not being the only company producing Modal and Lyocell, Lenzing is considered the most sustainable.

In contrast to other producers, they employ a closed-loop system to recycle nearly all water and chemicals instead of dumping them into the environment.

In addition to being environmentally friendly, Lyocell and Modal (especially TENCEL™) are also more robust, absorbent, and durable. Their elasticity and moisture resistance are superior to regular rayon but are generally more expensive.

What material is bamboo rayon?

Our following fabric news is about a common misconception about bamboo rayon: that it is a sustainable fabric. Bamboo is undoubtedly eco-friendly from the start.

In addition to its fast growth, the base grass does not require much water, pesticides, or herbicides to grow. Plants with rapid growth consume more carbon dioxide (and produce more oxygen) than plants with slower growth.

Turning bamboo into rayon also requires a great deal of chemical input. As you may recall from our article on bamboo fabric, around 50% of bamboo rayon’s chemicals are released into the atmosphere. We don’t want that to happen to our planet.

What material is cotton rayon?

Textiles such as cupro fabric (Cupra rayon) are made by recycling cotton garments or linter byproducts.

Cupra rayon isn’t for everyone, but if you’re looking for a vegan silk alternative and have found a transparent brand about how they produce it, it might be worth considering (if you promise to wear it forever!).

The Difference Between Rayon And Cotton

Sometimes, rayon is used instead of cotton as a cheaper alternative. Although rayon and cotton may be found in similar products like underwear, activewear, and industrial goods, they have some significant differences to consider.

  • Colors may fade more quickly with rayon because of its weak colorfastness.
  • Cotton’s durability is far superior to rayon’s. In addition to being more robust, cotton is water-resistant (whereas rayon loses some of its strength when wet).
  • Cotton is not as flammable as rayon, which is also very flammable.
  • Silky peace silk can be mimicked by rayon, but fancy silk dresses are hard to replicate with cotton.

Although rayon is semi-synthetic and cotton is natural, rayon biodegrades more efficiently than cotton. Rayon is among the best fabrics for beginners.

How eco-friendly is rayon compared to cotton? Cotton and rayon both play a role in this. Organic cotton still trumps even the most sustainable rayon, TENCEL™ Lyocell rayon (the cleanest crop on the planet).

Is Rayon Fabric Ethical?

What does this mean for rayon textile workers? Those chemicals sound scary, so what does this mean for them?

As you might remember from high school chemistry class, caustic soda and sulfuric acid aren’t the gentlest chemicals. Caustic soda’s corrosive nature can damage your eyes.

In addition to causing skin and eye problems, sulfuric acid (aka battery acid) can also cause reproductive complications, lung damage, and burns.

According to the National Institutes of Health, a mist contains human carcinogens. Carbon disulfide is another chemical that is especially problematic in rayon manufacturing.

About 150 years of evidence show that the colorless liquid has been harmful to workers while used in rayon production for as long as it has existed.

A unique and undesirable effect of carbon disulfide is that cellulose must be removed to make rayon. Still, removing the cellulose is necessary to further transform it into rayon.

As a result, the nervous system is adversely affected by a toxic degenerative brain disease. In addition to subtle personality changes, dizziness, anxiety, anorexia, vision changes, and Parkinson’s paralysis, this condition may manifest chronically over time.

Acute complications can also occur in the kidneys, blood, nerves, heart, liver, eyes, and skin outside the nervous system. Long-term exposure (i.e., garment workers) may result in mental deterioration and insanity.

Is Rayon Fabric Sustainable?

Another complication with carbon disulfide is that the environment is still unprotected from harmful effects, regardless of whether workers are adequately protected.

Carbon disulfide is released into the environment for every gram of viscose rayon produced. Since rayon production mainly produces carbon disulfide, it is no surprise that it is found in the environment.

When rayon enters the environment, it indirectly enters drinking water, animals, and humans. Furthermore, rayon must be produced in large factories with chemical storage and heavy manufacturing equipment. These trends affect Chinese, Indian, Indonesian, and Pakistani countries the most.

Because rayon is too toxic for EPA regulations, it isn’t produced in the U.S. due to the chemical-intensive process. Additionally, wood pulp from endangered forests is being sourced from deforested and other areas (e.g., biodiversity loss) due to the extraction of pulp for cellulose.

An estimate is that 30% of the world’s rayon comes from ancient and endangered forests. The look of a rayon jumpsuit does not justify these losses.

What is the biodegradability of rayon?

From an ecological viewpoint, rayon has one significant advantage: it’s biodegradable. A recent study found that rayon biodegrades more quickly than other fabrics (like cotton). However, a biodegradable item doesn’t necessarily mean that it can be thrown away in the garden heap.

Consider whether a torn rayon shirt has been processed with toxic chemicals before tossing it into your indoor compost bin. Keep this in mind when spreading your finished compost over your vegetable beds.

There is no doubt that rayon is (in almost all cases) not a sustainable fabric – which is good for us who wear greenwashing-proof spectacles.

Some fabric producers have changed their practices in response to this conscious commotion. However, the question remains, “Can rayon ever be eco-friendly?”

Growing numbers of companies are utilizing this material. Most top viscose producers have complied with the EU BAT (Best Available Techniques) criteria.

It measures many things, such as carbon disulfide requirements, freshwater, energy consumption, caustic soda use, and emissions. As a result, we are comfortable wearing two types of rayon fabric.

What is Rayon Used For?

Many people use this versatile material every day in a variety of household and industrial products:

  • Clothing—In the beginning, rayon was used to replace silk. However, it can also be used as a substitute for cotton and stand independently.
  • Silk Substitute – By nitrifying silk, Georges Audemars created the first artificial silk in 1855. As a result, he called the material “rayon.” Through a similar process, Hilaire de Charbonnet, the Comte de Chardonnet, created “Chardonnay silk” almost 30 years later. Ten years later, in 1894, Charles Frederick Cross, Edward John Bevan, and Clayton Beadle patented their viscose version.
  • Cotton Substitute—Some characteristics of rayon are similar to those of cotton. Despite their softness and breathability, they are both comfortable. Furthermore, both hold color well. Some rayons even use cotton fibers. The most crucial benefit of rayon, however, is that it is cheaper than cotton. Clothing manufacturers use rayon as a cotton substitute because of these reasons.
  • Yarn and Thread—All rayon yarns and yarns that combine rayon with other materials, such as wool, are called viscose, linen viscose, or vegan silk.
  • Bedding and Housewares—Rayon sheets, pillowcases, blankets, and bedspreads are popular because of their soft texture, breathability, and moisture-wicking properties.
  • Upholstery—While rayon isn’t durable enough as a standalone material for upholstery, it adds a softness to the fabric when blended with more muscular fibers. Upholstery fabrics made from rayon blends are popular.
  • Carpeting – Soft and dye-resistant, viscose rayon holds dye well. Area rugs made from this material are famous for this reason.
  • Medical Uses—Rayon can make cotton balls, wipes, cosmetic swabs, and dressings.
  • Tire Cords – Tire cords have been made from rayon since 1935.

What Is Rayon Material Like?

Since rayon is a silk substitute, it has a light and soft texture. The following are some of its other characteristics:

This shine is natural as a result of extrusion. There is a wide variety of appearances and intensities of this shine. Rayon can appear differently when viewed from different angles or under various lighting.

In addition to being breathable, rayon conducts heat well. In warm, humid climates, it is an ideal material for clothing. Among its many uses, rayon is a natural for cosmetics, medical applications, bedding, and home furnishings.

What are Rayon’s advantages and disadvantages?

Even though this fabric is revolutionary, it isn’t perfect for every application. Furthermore, it has unique drawbacks due to its unique qualities.

Rayon Advantages

  • Regarding industrial and home applications, rayon is an incredibly versatile fabric.
  • It has a natural shine and accepts dye well.
  • A high level of absorption is characteristic of rayon. The fabric is also moisture-wicking at the same time. Warm-weather clothing can be made from this material.
  • The natural properties of rayon make it resistant to mildew as well.
  • In addition, rayon does not accumulate static electricity.

Rayon Disadvantages

  • Rayon is a natural fiber, so it is not very strong. It is also less durable than silk or cotton because of its low resilience and lack of abrasion resistance.
  • Rayon is weakened by water. Hand-washing is recommended for most rayon items.
  • There is a tendency for rayon to shrink, sag, and wrinkle. Additionally, the edges are prone to raveling.
  • Rayon is heat-conducting, so heat can easily pass through it. It is a good fabric in warm weather but a poor one in cold weather.
  • There is a problem with the rayon holding its shape.

How Easy Is It To Sew Rayon?

What is the best way to sew rayon? It can be challenging. The rayon may slip, shifts and slides may occur, and pins and needles may leave their mark.

However, the biggest problem with sewing rayon is holding its shape. Fortunately, a few tips and tricks can simplify things.

Here are a few examples:

  • Choosing the Right Rayon—Working with pure rayon can be challenging. However, you might be able to simplify your job by using rayon blends on the market. You can combine rayon’s softness with polyester’s stability by choosing the right rayon blend.
  • Choose the Right Pattern – Flowing, and drapey garments are perfect for rayon’s light, silky texture. However, those with sharply shaped, tight-fitting items won’t like it so much. The right type of garment will maximize your chances of success.
  • Prewash – Some experts recommend pre-washing rayon fabric in a washing machine before sewing with it, even though the labels of rayon garments recommend handwashing or dry cleaning. As a result, rayon tends to shrink very quickly. Before you begin assembling your garment, you must remove any shrinkage.
  • Needles and Pins—Use needles and pins appropriate for the weight of your fabric. Ensure that both tools are sharp so you don’t make unnecessary holes in it.
  • Rotary Cutter – A rotary cutter can provide greater accuracy when cutting rayon, according to some experts.
  • Stitch Curves and Edges – Stay stitch curves before assembling your pieces to help them maintain their shape. Keep your raw hem edges from unraveling by stitching them.
  • Give it a Rest – Heming, your almost-finished garment, can be done after it has been hung on a hanger for 24 hours. The reason for this is that rayon tends to sag and bag. You can sew the hem after the fibers have settled into their final configuration by hanging it.

How Durable Is Rayon?

Unfortunately, rayon isn’t very durable. Abrasion and shrinkage are common problems. Over time, the shape can be lost. Getting wet also weakens the fibers.

However, the durability of some rayon blends varies. There are rayon blends with cotton, wool, and linen.

How to Care for Rayon?

The feel and look of rayon garments are lovely. How can you do it if you want them to look their best? How can you fix the worst-case scenario if it happens?

What Is The Best Way to Clean Rayon?

First and foremost, you should dry-clean your clothes. However, if you intend to wash the garment yourself, you should treat it delicately. In other words:

  • Mild detergent
  • Cold water
  • Machine wash on a gentle cycle or hand wash
  • The garment should be turned inside out and washed inside a mesh bag when being machine-washed
  • The fabric should never be twisted or wrung. Instead, squeeze gently.
  • Dry by hand only.
  • The garment should be air-dried flat or hung on a padded hanger.

When rayon is washed, it shrinks, no doubt about it. Its color and softness can also fade. Modal and Lyocell are better suited to machine washing, and they have chemical finishes. However, it’s still important to handle them delicately and avoid using a dryer.

When rayon garments are air-dried, they might be stiff, scratchy, and wrinkled. Ironing can reduce wrinkles, but you must be extremely cautious.

How to Iron Rayon?

It’s almost as tricky as washing delicate fabrics like rayon as ironing them. Getting the fabric scorched is the greatest danger. Rayon can also be left with an unattractive shine after ironing. As a result:

  • You should set your iron to medium heat (setting 3).
  • Your garment should be placed between the iron and a pressed cloth.
  • To be safe, iron the garment on the wrong side.

Getting wrinkles out of rayon might initially seem intimidating, but it’s pretty simple once you know how.

How to Shrink Rayon?

For example, when prewashing rayon before sewing with it, you might want to shrink it. It’s simple. You can do it safely in a few ways.

Method 1: Hand Washing

To begin with, gently hand wash it and soak it in water for several minutes.

Once the fabric has been dried, it can be used. Press out the excess water and air-dry your flat or hung fabric if you want subtle shrinkage.

Use the gentle setting if you want your fabric to shrink more dramatically.

Method 2: Machine Washing

Due to the possibility of shrinkage, we recommended against machine washing earlier. However, to shrink your rayon, use warm or hot water and cycle gently. Turn your garment inside out and wash it in a mesh bag.

In addition to air drying your fabric, you can use the dryer’s gentle cycle to maximize shrinkage.

How to Unshrink Rayon?

The best defense against rayon shrinking is to prevent it from shrinking in the first place. In any case, there is no need to worry once the deed has been done. You can take a few steps. Even if you can’t restore your garment precisely to its original state, you may be able to improve it.

Method 1: Relax and Stretch

Imagine your shrunken fibers as tense muscles. It’s time to wrap them in a fuzzy towel and give them warmth and TLC.

  1. Put warm water (not hot!) in a bucket.
  2. If you want to add conditioner or baby shampoo, add one capful.
  3. Relax the fibers of your garment by soaking it in warm water and gently massaging it.
  4. Cold water should be used to rinse your garment.
  5. Make sure the excess water is pressed out. Avoid wringing!
  6. Place your garment on a towel.
  7. Place your garment inside the towel and gently roll it up. The fibers will be stretched.
  8. More water can be released by pressing.
  9. It is time to unroll the towel.
  10. Resize the garment by gently stretching it with your hands.
  11. Lay your garment flat to dry.

Method 2: Steam Ironing

Moisture, heat, and warmth. What’s the theme here? Steam ironing can also restore your rayon garment to its original shape. The following steps will guide you through the process.

  1. Prepare a spray bottle by filling it with warm water.
  2. The lowest setting on your steam iron should be used.
  3. It would be best to lay your garment flat on the ironing board after turning it inside out.
  4. It would be best if you spritzed your garment with water.
  5. Be gentle when ironing your garment. Don’t let it dry out.
  6. Regain the garment’s original dimensions by stretching it gently.
  7. Put your garment on a non-metal hanger or air dry it.
  8. If you weigh down the fabric while drying or use clothespins to hold it in place, you can increase its stretch.

Can Rayon Be Considered Eco-Friendly?

It’s a good question. A sustainable crop like bamboo is often used as a source of waste materials for rayon production, which is great.

While eco-friendly materials are environmentally friendly, processing them involves enormous amounts of toxic chemicals. As an exception, modal and lyocell are produced by reusing chemicals rather than releasing them.

Further confusing matters, rayon is biodegradable in some form. The biodegradability of viscose is even faster than that of cotton. What is the eco-friendliness of rayon? Yes, in some ways. The situation is different in other ways.

Are There Alternatives to Rayon?

Natural fabrics like silk and cotton were cheaper before rayon was invented. It’s still worth considering these options even if price isn’t your top concern.

An excellent alternative to cotton is linen, made from flax fibers. Warm weather makes it an excellent choice, and its ease of use also makes it great.

The feel of hemp fabric is similar to that of cotton and linen. Compared to cotton crops, hemp uses half the amount of water. A woven or knitted fabric can also be used.

Rayon FAQs

What is rayon, and how is it produced?

Rayon is a semi-synthetic fiber derived from natural sources of regenerated cellulose, such as wood and agricultural products. It undergoes a solubilizing process to be turned into fibers. The most common production methods are the viscose process, using alkali and carbon disulfide, and the Lyocell process, which uses amine oxide and is more environmentally friendly.

What are the different types of rayon, and what are their properties?

Rayon comes in various types, mimicking the texture and feel of natural fibers like silk, wool, cotton, and linen. Types resembling silk are often termed artificial silk. Rayon is versatile, soft, smooth, and absorbent, making it suitable for hot and humid climates. However, it does not always insulate body heat well. High-wet-modulus (HWM) rayon is stronger and more durable than regular rayon.

Can you explain the environmental impact of rayon production?

The production of rayon, especially using the viscose process, has been criticized for its environmental impact. This method generates significant amounts of contaminated wastewater and uses toxic chemicals like carbon disulfide. The Lyocell process, however, is less harmful and avoids neurotoxic chemicals. Rayon is more biodegradable than some synthetic fibers, but its manufacturing process, particularly in developing countries, raises concerns about deforestation and carbon disulfide emissions.

What are the main uses of rayon in textiles?

Due to its silk-like feel, rayon is extensively used in clothing, making it a popular choice for dresses, blouses, and linings. It’s also used in home textiles like bed linens and upholstery. Its ability to blend with other fibers, like cotton and spandex, enhances its versatility in various fabric compositions.

How should rayon products be cared for?

Care for rayon products depends on the type. Regular viscose rayon is typically dry-cleaning only, as it is less durable when wet. HWM rayon, on the other hand, can be machine-washed. To maintain the quality and longevity of rayon fabrics, it’s essential to follow specific care instructions on garment labels.

Conclusion

Plant fibers are chemically processed to make rayon, a semi-synthetic fabric. Rayon is suitable for textile manufacturing, medical applications, and industrial uses.

Producing rayon from natural materials is generally eco-friendly and sustainable. However, rayon production can lead to high levels of pollution. The biodegradability of rayon varies depending on the type.

The versatility of rayon is unmatched. It can also be delicate. Special care must be taken when cleaning and sewing with it.

However, rayon remains one of the most affordable alternatives to silk and cotton. The silky texture and durability of this fabric are unparalleled.
