Bamboo viscose is a soft and silky man-made cellulosic fibre (MMFC) extracted from bamboo plants.

• Bamboo fibre is known for its breathable, cooling and smooth properties.
• Bamboo's natural habitat includes regions with mild winters and abundant rainfall, such as the Sichuan province in China, a leading exporter globally.
• A key advantage of bamboo is its rapid growth rate. It can reach up to 1 metre per day without the need for pesticides or fertilisers.
• The base of the bamboo plant can be harvested again within 3-5 years, unlike cotton, which is harvested twice a year, leading to greater soil stress.
• Bamboo uses only a third of the water required by cotton.
• Bamboo is effective in CO2 sequestration, with an average of one hectare of bamboo stands absorbing about 17 tonnes of carbon annually. 
• Demand for viscose is expected to double over the next eight years, increasing pressure on deforestation. At DUALLE, we choose FSC-certified viscose to promote deforestation-free practices, support biodiversity, and protect local communities. 
• Our bamboo yarn is also OEKO-TEX® certified, guaranteeing that it is free from harmful substances and safe for human health.
• Bamboo fibre is considered 100% biodegradable in soil, though the decomposition rate and method can be affected by synthetic additives and chemical dyes used in textiles.
• A small percentage of polyamide and elastane is blended into the bamboo fabric to provide additional elasticity, a better fit and increased comfort.

Method: Cold dyeing
Dyed in: Aosta Valley, Italy

• We use a new, innovative cold dyeing method to dye the majority of our textiles in a small atelier in the Italian Alps.
• Our innovative method involves very low water consumption, using up to five times less water than warm dyeing.
• The process uses minimal energy since it avoids prolonged heating; yarn and garments are aired at room temperature.
• The dye bath can be reused multiple times.
• Only natural ingredients, such as different trees, plants, roots, fruits are used in our dyes.
• Our drying process can take up to three weeks, depending on weather conditions, making it longer than warm dyeing methods.
• The absorption of colour in our natural fibres is much stronger due to the extended drying time in the open.
• Our yarns and textiles achieve the highest scores in standardised dyeing tests (ISO Standards) for sun exposure, friction, and wash fastness.
• The ingredients used in the dyes have antioxidant, antimicrobial, anti-moth, and anti-UV properties.
• Over time, our natural dyes can feel beneficial on the skin, especially for sensitive skin, and promote comfort through odour control.
• Deep black and white are the most challenging colors to achieve with natural dyes, with no current textile industry solutions. Thus, we use an eco dye process for these colors, which is more responsible than traditional methods in terms of resource use and environmental impact.
• Large-scale production for natural dyes and their long processing times are still a hurdle in the textile industry and more research is required to promote wider adoption and more cost-efficient solutions. 

Recommended to wash at 30°C in DUALLE’s laundry bag with mild detergent, eco-labelled if possible.
