What is Cupro Fabric?
Invented first in Germany in the 1900s, Cupro or Cuprammonium rayon is a semi-synthetic fabric made of cotton linter, a by-product of cotton which is considered as textile waste. This cotton linter is a by-product of cotton that is too tiny to spin and would otherwise become textile waste. After undergoing heavy processing, Cupro becomes a much softer fabric than conventional cotton, having a similar weight, luster, and silky feel. Cupro can also be extracted from recycled cotton garments.
Cupro is also known as Ammonia silk and Bemberg (the American patented name by the company J.P. Bemberg). The cupro fabric is thin, silky, and sheer, making it perfect for form-fitting dresses. Coordinated with other materials, apparel like t-shirts, blouses, intimate wear, scarves, etc. can also be produced from cupro. Indeed a curious combination of plant-based fibers, processed with chemicals but resembles silk.
Currently, China is the leading producer and exporter of cupro. Apart from China, Asahi Kasei Corporation also produces a large portion of the world’s cupro fabric. However, environment-friendly cupro fabric is, its processing does involve large quantities of toxic chemicals like caustic soda, ammonia, and copper. All these chemicals if not disposed off carefully may end up causing more harm than good to the environment.
How is Cupro Fabric Made?
Cupro or Cuprammonium rayon is made of regenerated cellulose from cotton linter (the fluff that sticks around the cotton seeds after being harvested). As part of the production process of cupro, these fuzzy cotton fibers are immersed in a mixture of copper and ammonia, resulting in a new substance, which is again soaked into a caustic soda solution
After being dunked into chemical solutions at different levels, the final substance gets pushed through spinnerets to form threads. These threads undergo a variety of hardening baths to rebuild the cellulose and eliminate the presence of ammonia, copper, and caustic soda remnants, making the threads fit to be woven into cupro fabric.
Is Cupro Fabric Sustainable?
Cupro is a plant-based fabric, making it cruelty-free, vegan, and 100% biodegradable, however, it is not a fully sustainable fabric. In addition, it is made of cotton by-products and since conventional cotton production is a wasteful and water-intensive process, using every bit of the cotton helps massively in environmental conservation. Also, unlike silk and its dry-cleaning requirements, cupro is machine-washable which makes it more eco-friendly. So yes, definitely a step closer to being a sustainable fabric.
Asahi Kasei Corporation, a leading producer of cupro globally has announced zero emission and energy conservation goals in its cupro production process. This company thoroughly recycles 100% of the waste generated during Cupro processing. The Asahi Kasei Corporation’s Cupro is Eco Mark certified which is a recognized certification by the Japan Environment Association.
But Wait! Cupro production is not all glitters. If cupro is not manufactured in a closed-loop system where its toxic waste is recycled and reused, it may have a severe impact on the environment. As we’ve already mentioned, China is the largest producer of Cupro, and this country’s textile factories are infamous havens for both reckless usage of harmful chemicals and the modern-day slave system.
With zero efforts towards environmental conservation, China has mastered the science of making money by transforming waste products into cheap semi-synthetic and synthetic fabrics. Cupro manufacturing is inexpensive because Hello! we’re talking cotton waste, ammonia, caustic soda, and copper, all of which, well, are downright cheap and highly toxic.
Is Cupro Fabric Affordable?
Yes, cupro fabric is quite cheap compared to natural fabrics like linen, cotton, silk, and hemp. However, it undoubtedly gives a soft, smooth, and silky feel just like the exotic and expensive silk fabric. Since the base material of cupro remains to be cotton linter, a huge amount of this textile waste can be acquired at very little price. All the cupro manufacturers need to do is, whip this cotton waste into a mixture of cheap toxic chemicals and form a totally new material.
Cupro is affordable because it is sold at extremely low prices but with enormous profit margins, making it a win-win for both the consumers and the producers.
Cupro Fabric Certifications
Cupro production has ended in the United States because manufacturers were unable to observe basic water and air protection regulations. But some sustainable brands do work with certified cupro as their base fabric. So far a sustainable cupro manufacturer can apply for these 3 certifications.
