In the evolving landscape of sustainable textiles, cupro fabric has emerged as a frontrunner for brands seeking eco-conscious luxury. Because let’s face it, nobody wants to wear a plastic bag in the name of sustainability.
You likely struggle to find a material that mimics the effortless drape of silk but maintains the breathability and practical durability of cotton—the “unicorn” of textiles, if you will.
This balance is particularly vital for lingerie manufacturers, who know better than anyone that “itchy” and “intimate” are two words that should never go together. This guide provides a technical breakdown of Cupro’s properties and commercial applications.
You will gain the critical data needed to confidently integrate this regenerated fiber into your product lines, ensuring your collections meet modern demands for both style and sustainability.

What is Cupro Fabric?
Cupro fabric is a regenerated cellulose fiber made from the waste fibers found on cotton seeds, known as cotton linter. This makes it a unique and eco-friendly alternative because it uses byproducts that would otherwise be discarded. You might also hear Cupro called Cuprammonium rayon, Cupra, ammonia silk, or Bemberg.
| Parameter | Specification |
|---|---|
| Fiber Type | Regenerated cellulose (cotton linter-based) |
| Fabric Weight | 80-180 GSM (typical range) |
| Weave Types | Plain, twill, satin, jersey knit |
| Tensile Strength | 2.0-2.6 g/denier (dry) |
| Moisture Regain | 11-13% |
| Shrinkage Rate | 3-5% (first wash) |
| Abrasion Resistance | Moderate to high |
| Dyeing Temperature | 60-80°C |
| Colorfastness | Grade 4-5 (wash/light) |
How Cupro Fabric is Made
The production of Cupro fabric involves a detailed process:
- First, cotton linter is collected as the raw material.
- It’s then dissolved in a special copper-ammonia solution, creating a viscous liquid called spinning dope.
- This liquid is pushed through tiny holes into a bath where it solidifies into fibers.
- These fibers are washed, neutralized, and spun into yarn for fabric weaving.
This process is impressive because it recovers about 98% of the chemicals used. That’s much more efficient and eco-friendly than traditional methods, which only recover 50%-60%. This closed-loop system helps reduce environmental impact significantly.
Properties of Cupro Fabric
When you choose Cupro fabric, you get a unique blend of comfort, durability, and style. Here are some key properties that make Cupro stand out for your products:
Lightweight with Versatile GSM Options
Cupro fabric typically ranges from 80 to 180 gsm (grams per square meter). This makes it perfect for lightweight fashion items. For example:
- A blend of 55% Cupro and 45% EcoVero Viscose weighs about 125 gsm.
- Another mix of 54% Cupro and 46% EcoVero Viscose comes at 150 gsm.
These weights give you flexibility in creating different garments tailored for various climates and uses.
Exceptional Breathability and Moisture Management
Cupro is known for its high breathability, allowing excellent airflow. It performs better than many synthetic fabrics in handling sweat, keeping garments fresh. Its moisture regain rate of 11%-13% is close to natural silk, meaning it absorbs sweat efficiently and releases it quickly. So, your products will feel dry and comfortable throughout the day.
Thermal Regulation
One of Cupro’s standout features is its low heat retention and excellent thermal regulation. It keeps you cool in the summer by letting heat escape and offers gentle insulation during the cooler months. This adaptability adds value and comfort to any collection.

Benefits of Cupro Fabric
Cupro fabric offers you an impressive range of advantages that make it a smart choice for your products. Here are the key benefits:
Silk-like Feel with Affordable Luxury
- Soft and smooth texture: Cupro feels incredibly silky and cool against the skin. It rivals natural silk in softness, giving garments a luxurious drape without the high price.
- Vegan and sustainable alternative: Unlike silk, Cupro uses cotton waste and requires less energy, making it an eco-friendly luxury that suits conscious consumers.
Superior Breathability and Moisture Management
- Highly breathable: Cupro outperforms many synthetics by allowing air and moisture to pass through easily, keeping wearers cooler and drier.
- Thermoregulating properties: It helps regulate body temperature by cooling in summer and warming in winter, thanks to its natural cellulose base.
- Moisture-wicking: Like cotton, it absorbs sweat quickly and reduces odor, which means less frequent washing and improved comfort.
Durability and Easy Care
- Strong and resilient: Cupro is more durable than silk, resisting wrinkles, shrinkage, and pilling. It holds its shape well, keeping products looking new longer.
- Easy maintenance: Machine washable on gentle cycles, Cupro maintains dimensional stability, making it hassle-free for consumers.
Eco-Friendly and Sustainable
- Made from cotton linter waste: This closed-loop process recycles solvents, minimizing environmental impact.
- Biodegradable within 6 to 12 months: Unlike synthetic fibers that last over 200 years in landfills, Cupro breaks down quickly, supporting a circular economy.
- Certified quality: Available with OEKO-TEX STD 100, GOTS, and BSCI/SEDEX certifications, ensuring ethical and sustainable production standards.
Vibrant Colors and Versatile Use
- Excellent dye uptake: Cupro takes dyes well, resulting in vivid, fade-resistant colors that meet Pantone standards, ideal for fashion brands requiring consistent color quality.
- Multi-purpose fabric: Perfect for linings, dresses, blouses, scarves, and even activewear. Its fine jersey and sateen weaves provide versatility across many apparel lines.
Expert Advice: Replace standard polyester linings with Cupro in your premium tailored garments. This change cuts down on static cling and boosts breathability. By addressing the common complaint of “sweaty” linings, you can easily justify a higher price.

FAQs About Cupro Fabric
1. Is the production of Cupro truly biodegradable?
Yes, as a cellulose-based fiber, the fabric itself is biodegradable and compostable at the end of its lifecycle. To make a sustainable claim, brands must ensure their manufacturing facility uses a closed-loop system. This system recovers ammonia and copper used in processing, which helps prevent water pollution.
2. How does Cupro handle moisture and temperature regulation?
Cupro is microporous, meaning it breathes and wicks moisture rapidly—often faster than cotton. It regulates temperature. In summer, it keeps you cool by wicking away sweat. In cooler seasons, it retains body warmth. This provides year-round versatility for fashion collections.
3. What is the difference between Cupro and standard Viscose?
While both are regenerated cellulose fibers, the raw material differs. Viscose is typically made from wood pulp, whereas Cupro is made from cotton linter. Cupro has a smoother, rounder fiber cross-section. This leads to a silkier feel and improved moisture management when compared to regular viscose.
