Cork Fabric – Production, Properties & Applications
How Natural Cork Becomes a Flexible Textile Material
Cork fabric combines the characteristic surface of natural cork with the flexibility of a textile backing material.
To produce it, cork is processed into very thin layers and bonded to a flexible backing. This creates a material that, depending on the specific type, can be cut, sewn, glued and processed into a wide variety of products.
The natural structure of the cork remains visible on the surface. Pores, grain patterns and slight variations in colour are part of its characteristic appearance and make every cut unique.
Thanks to its special combination of natural cork surface, low weight and textile flexibility, cork fabric is used for bags, wallets, accessories, jewellery, home accessories and creative projects, among other applications.
At korkie, we have also been working with cork fabric in our own workshop for many years. This allows us to share not only our knowledge of the material in this guide, but also practical experience in processing and care.
👉 Which Type of Cork Is Right for Your Project?
What Is Cork Fabric?
Cork fabric is a multi-layer material with a surface made from genuine cork.
The visible cork layer is processed to a very thin thickness and bonded to a flexible textile backing. This creates a material that combines the natural look and feel of cork with properties that allow it to be processed like a textile.
Cork fabric is therefore sometimes also referred to as cork leather. This term mainly describes its leather-like applications and processing possibilities. However, cork fabric is not animal leather.
Depending on the specific type, cork fabrics can differ in terms of:
✔ Thickness
✔ Backing material
✔ Surface structure
✔ Colour and grain
✔ Coating or surface treatment
✔ Flexibility
✔ Stretch behaviour
💡 Good to Know
Cork fabric is neither solid natural cork nor agglomerated cork.
The visible surface is made from genuine cork, which is processed into a very thin layer and bonded to a flexible backing material.
As a result, cork fabric has different processing properties from cork sheets or cork rolls and can, for example, be sewn.
How Is Cork Fabric Made?
Cork → selection and preparation → thin cork layer → bonding to textile backing → surface finishing → cutting and further processing
1. The Cork Is Prepared for Further Processing
The process starts with natural cork. Suitable cork material is prepared so that a very thin and even cork surface can be produced.
2. A Thin Cork Layer Is Produced
The cork is processed into a very thin layer. This preserves the characteristic natural cork structure while making the material considerably more flexible than solid cork bark.
3. The Cork Layer Is Bonded to a Backing
To make the thin cork surface stable while retaining its flexibility, it is bonded to a textile backing material.
The exact construction can vary depending on the cork fabric quality.
4. The Surface and Design Are Created
Depending on the specific type, cork fabric can retain its natural appearance or be further finished and decorated.
Examples include:
✔ Natural-coloured cork surfaces
✔ Coloured varieties
✔ Printed designs
✔ Metallic effects
✔ Different grain patterns and structures
5. The Finished Cork Fabric Is Further Processed
The finished material can then be cut, sewn, glued and processed into a wide variety of products.
Technical Properties of Cork Fabric
Despite its very thin cork surface, cork fabric is a flexible and durable composite material. Its properties result from the interaction between the cork layer, bonding layer and backing material.
For one tested cork fabric quality for which technical documentation is available to us, the following values are specified:
| Property | Documented value |
|---|---|
| Tensile strength | 20 kg / 3 cm |
| Elongation – weft direction | ≥ 20% |
| Elongation – warp direction | ≥ 15% |
| Tear strength | 1.8–2.5 kg / 3 cm |
| Peeling strength | ≥ 2 kg / 3 cm |
| Abrasion resistance | 50,000 Martindale cycles |
Tensile strength was tested according to ISO 13934-1, tear strength according to ISO 13937, and abrasion resistance according to ISO 12947-1 Martindale.
💡 Good to Know
These values refer to one tested cork fabric quality for which technical documentation is available to us and should not be applied generally to all cork fabrics.
The backing material, cork layer and overall construction influence the technical properties of the finished material.
Different Backing Materials for Different Applications
Cork fabric can be produced with different backing materials. Which type is most suitable depends on what the material will ultimately be used for.
Depending on the manufacturer and quality, possible backing materials include:
✓ Cotton
✓ Polyester
✓ Polyester-cotton blends
✓ Non-woven backing
✓ Other textile composite backings
The technical data sheet for one quality documented by us specifies, for example, a textile composition of 65% polyester and 35% cotton. Other cork fabric qualities may have a different construction.
The backing has a significant influence on how cork fabric can be cut, sewn, shaped and subjected to stress. When selecting the material, it is therefore important to consider not only the visible cork surface but also the reverse side and the overall material construction.
Dyeing, Printing, Embossing and Laser Processing Cork Fabric
The natural cork surface offers numerous possibilities for creative design.
Depending on the cork fabric quality and manufacturing process, the surface can, for example, be:
✓ Dyed
✓ Printed
✓ Embossed
✓ Laser processed
✓ Finished with special-effect surfaces
✓ Lacquered or sealed
This creates a wide variety of colours, patterns and surface structures in addition to natural-coloured cork fabrics. Depending on the design, the characteristic cork structure remains more or less visible.
However, not every surface treatment is suitable for every cork fabric quality. When printing, dyeing, embossing or laser processing cork fabric yourself, the material construction, backing and existing surface finish should be taken into account.
We recommend testing the process on a leftover piece before working on the final material.
Sewing Cork Fabric – What Should You Consider?
Thanks to its flexible textile backing, cork fabric can be sewn and made into bags, wallets, cases, accessories and many other products.
In our own workshop, we process cork fabric using industrial sewing machines. We use a special waxed thread, whose waxed surface helps the thread pass smoothly through the material and works well with the cork fabrics we use.
The appropriate needle, thread tension and stitch length depend on several factors:
✓ Specific cork fabric quality
✓ Material thickness and backing
✓ Number of material layers being sewn
✓ Type of sewing machine used
✓ Thread and desired seam
✓ Intended stress on the finished item
For this reason, we deliberately do not recommend a universal needle size or stitch length for cork fabric.
💡 Good to Know
Although cork fabric can be sewn, it does not behave exactly like a conventional woven fabric.
A needle puncture leaves a permanent hole in the material. Repeatedly unpicking and resewing in the same place should therefore be avoided wherever possible.
Pins can also leave visible puncture marks. Depending on the project, sewing clips or other fixing methods that do not create additional holes may be more practical.
🛠 Workshop Tip from korkie
Before sewing a larger project, test the seam, thread and machine settings on a leftover piece of the cork fabric you intend to use.
In our workshop, we use industrial sewing machines and special waxed thread. Settings from our professional production process therefore cannot automatically be transferred to domestic sewing machines.
The important thing is to achieve a clean seam without unnecessarily perforating the material and to ensure that the processing method is appropriate for the intended stress on the finished item.
Cutting Cork Fabric – Clean and Precise Cuts
Due to its relatively low material thickness, cork fabric is comparatively easy to cut.
Depending on the project, suitable tools include sharp scissors, a rotary cutter or a sharp cutting knife.
For visible pieces, attention should be paid not only to shape and dimensions but also to the grain, structure and colour variations of the cork surface. Especially when several pieces belong together, the orientation of the cork structure can significantly influence the appearance of the finished product.
🛠 Workshop Tip from korkie
Before making the first cut, check not only the dimensions but also the orientation of the cork surface.
When working with several matching pieces, we recommend arranging all cutting positions on the material first and cutting them only once the overall layout has been determined.
Cleaning and Caring for Cork Fabric
Cork fabric is comparatively easy to care for in everyday use. Light dirt on our cork fabric products can usually be carefully removed using water, curd soap and a soft cloth.
As cork fabrics can be natural, dyed, printed or surface-treated depending on the specific version, we recommend testing the cleaning method on an inconspicuous area first if the surface is unfamiliar or particularly delicate.
You can find detailed cleaning and care instructions in our dedicated care guide. We also show in a video how cork and cork fabric can be cleaned in practice.

Gluing Cork Fabric – Consider the Material and Backing
Depending on the project, cork fabric can be glued or bonded in addition to being sewn.
The appropriate adhesive depends on the cork fabric quality, backing material, material it is being bonded to and subsequent stress. An adhesive should therefore not be selected solely because it is generally described as being “suitable for cork”.
The reverse side is particularly important: different cork fabrics can use different textile backings. An adhesive that works well with a cotton backing may therefore not automatically be suitable for every other cork fabric quality.
🛠 Workshop Tip from korkie
Before carrying out larger bonding jobs, make a test bond on a leftover piece.
Check not only whether the bond is strong enough, but also whether the adhesive shows through on the front, changes the surface or affects the flexibility of the cork fabric.
For items subject to greater stress, a sewn or combined connection may be more suitable, depending on the construction.
What Is Cork Fabric Used For?
The combination of a natural cork surface, flexible backing material and good workability makes cork fabric suitable for a wide variety of products.
Typical applications include:
✓ Bags and backpacks
✓ Wallets and cases
✓ Key and coin pouches
✓ Jewellery and fashion accessories
✓ Shoes and footwear details
✓ Home accessories and decoration
✓ Upholstery applications
✓ Creative sewing and DIY projects
Cork Fabric in Our Own Workshop
At korkie, we also process cork fabric in our own workshop – particularly for bags, wallets, cases and accessories.
Depending on the product, we combine different cork fabric designs, colours and surfaces. Which cork fabric quality is most suitable depends on factors such as backing material, material thickness, flexibility, intended stress and surface finish.

Is Cork Fabric Water-Repellent?
Yes. The cork fabrics we use for bags and accessories are water-repellent and have proven themselves very well in everyday use, even in heavy rain.
When exposed to rain, the outer surface generally becomes wet first and then dries again. No additional waterproofing treatment is required for normal everyday use.
It is important to distinguish between the two terms: water-repellent does not mean waterproof. With a finished bag, seams, zips, edges and the overall construction also play a role.
Does Cork Fabric Transfer Colour When Wet?
The cork fabrics we use are colourfast and do not transfer colour onto clothing during normal use, even when exposed to rain. This also applies to our dyed and printed cork fabrics.
💡 Good to Know
Got wet? Simply allow the material to dry at normal room temperature. There is no need to use strong heat from a radiator or hair dryer.
👉 How to Clean and Care for Cork
How Natural Is Cork Fabric?
The visible surface of cork fabric is made from genuine cork. However, cork fabric is not a pure natural cork product, but a multi-layer composite material.
Depending on the quality, it may include:
✓ Natural cork or agglomerated cork
✓ Textile backing material
✓ Bonding layer
✓ Colour finish or print
✓ Lacquer or sealing layer
The exact composition can vary depending on the specific cork fabric quality.
Is Cork Fabric Vegan?
Cork itself is a plant-based raw material, and cork fabric is often used as an alternative to animal leather.
However, whether a specific cork fabric can be described as vegan also depends on the backing material, adhesive, surface finish and other components. Any such claim should therefore always refer to the specific material quality.
Cork Fabric and Sustainability
The cork component of cork fabric is based on a renewable raw material. The cork oak is not felled when the cork is harvested; its bark regenerates and can be harvested again.
However, cork fabric does not consist exclusively of cork. Depending on the quality, textile backings, bonding layers and surface treatments are also part of the composite material.
Cork fabric should therefore not generally be described as “100% natural” or “fully biodegradable.”
Its distinctive feature lies in combining a very thin cork surface with a flexible and versatile backing material.

Cork Fabric, Leather or Faux Leather – What Are the Differences?
Cork fabric is often used as an alternative to leather or faux leather because of its appearance, flexibility and processing possibilities. However, the materials differ fundamentally in their construction.
Cork fabric: A cork surface on a flexible backing material. Depending on the quality, bonding layers and surface finishes may also be used.
Leather: Made from animal hide and processed using various tanning and finishing methods.
Faux leather: Typically consists of a backing material with a synthetic surface layer.
Cork fabric is therefore neither leather nor conventional faux leather, but a distinct cork composite material.
🌿 Conclusion – Cork Meets Textile
Cork fabric combines a genuine cork surface with a flexible backing material, creating a versatile composite material that can be processed in many different ways.
Depending on the quality, cork fabric can be cut, sewn, glued and finished in a variety of ways. It is used to create products such as bags, wallets, cases, accessories, shoes and home products.
From our own workshop experience, we know how versatile the material can be in practice. However, the specific cork fabric quality is always important, as the cork layer, backing material and surface finish can vary considerably.
