What is Cupro Fabric – The Ultimate Guide

The textile industry has evolved to meet the changing needs of people. In today’s world, individuals not only prioritize comfort in fabrics but also seek environmentally friendly options. Not only does cupro fabric meet these requirements, but it also serves as a vegan alternative to silk. This post will show you the world of cupro fabric.

What is Cupro Fabric?

Cupro fabric, also known as Cupra, cuprammonium rayon,  ammonia silk, and Bemberg, is a semi-synthetic, regenerated cellulosic fabric made from cotton linter fibers. It shares similarities with silk, a lightweight feel, and excellent breathability. Due to these qualities, it is highly esteemed in the industry.

What is the History of Cupro Fabric?

The origin of cupro fabric can be traced back to the late 19th century. In 1897, the German company J.P.Bemberg pioneered the industrialization of cupro fibers with a new manufacturing method. 1928 Asahi Kasei Corporation introduced this technology in Japan, and production commenced in 1931. It was marketed as an exclusive product under its brand name, Bemberg.

Once introduced, this fabric quickly gained popularity. During World War II, when silk became scarce and expensive, cupro fabric emerged as the preferred choice. Today, as people’s environmental concerns have grown, the demand for cupro fabric has increased. China has become the primary producer of cupro fabric.

How is Cupro Fabric Produced?

The primary raw material used in producing cupro fabric is cotton linter, which refers to the short fibers that may be discarded during cotton production and processing.

The production begins by dissolving the short cotton fibers wrapped around the cotton seeds in a copper ammonia solution prepared from copper hydroxide or alkaline copper salts. The dissolved cellulose solution is then carefully filtered to remove impurities or undissolved fibers.

Next, the filtered solution is extruded through spinnerets to form fine filaments. These filaments are then immersed in a coagulation bath containing sulfuric acid, solidifying them into a more robust state.

The solidified long filaments undergo a thorough washing process to eliminate impurities and residual chemicals. They are subsequently aged to enhance their strength and stability. The aged filaments are then spun into yarns and processed into fabrics.

Cupro fabric can also undergo additional finishing processes, such as dyeing, printing, or other special treatments, according to your specific requirements. These options allow you to confidently explore a wide range of creative possibilities with these fabrics.

Environmental Impact of the Cupro Fabric

Positive Impact

Cupro fabric is considered environmentally friendly as it utilizes cotton linter, a byproduct of the cotton industry, as its raw material. This efficient use of the raw material helps reduce waste, making cupro fabric an eco-conscious choice. Additionally, cotton is a renewable resource, further enhancing the sustainability of cupro fabric.

Cupro fabric is biodegradable, meaning it naturally decomposes over time without causing long-term harm to the environment. This characteristic aids in minimizing the accumulation of synthetic waste in landfills. Furthermore, the closed-loop production process of cupro fabric promotes resource recycling, including the reuse of various chemical solvents. This approach effectively reduces pollution and minimizes the impact on water resources.

Negative Impact

The production of cupro fabric has certain drawbacks, including its energy-intensive nature and significant water and electricity consumption. Specifically, the stages involving dissolution and washing require substantial amounts of water. This can strain local water resources, especially in areas already facing water scarcity.

Furthermore, the production process of cupro fabric involves using chemicals such as copper hydroxide and sulfuric acid. Mishandling of these chemicals or the absence of closed-loop production processes can result in the discharge of wastewater containing chemicals or residual substances. This not only pollutes water and poses a threat to aquatic ecosystems but also has the potential to contaminate soil.

However, it’s important to note that cupro fabric itself adheres to sustainability principles and is more environmentally friendly than other synthetic fabrics. When making a purchase, you have the option to choose manufacturers that strictly implement sustainable practices and employ closed-loop production. This ensures proper chemical management, water conservation measures, and responsible waste management.

Cupro fabric is equally suitable for household textiles, whether it’s commonly used bedding like sheets and duvet covers, or curtains and interior decorations. It delivers outstanding performance in these applications.

How to Care for Cupro Fabric?

Whether it’s cupro fabric or any other textile, when it comes to cleaning, the first and crucial step is to check the care label and understand the specific care instructions. This ensures that the fabric remains undamaged due to improper care.

Whether you choose machine washing or hand washing, you should avoid using bleach or harsh chemicals. When machine washing, use gentle cycles with cold water.

Afterward, dry the fabric by either hanging it or laying it flat. Since cupro fabric is prone to wrinkling, ironing can help restore its smooth appearance. However, make sure to use a pressing cloth and iron at a low temperature, as high temperatures may cause the fabric to shrink or deform.

Is Cupro Fabric Better than Cotton?

While both cupro fabric and cotton are derived from cotton fibers, cupro fabric stands out with its smoother and more delicate texture, often serving as an alternative to silk.
