The viscose fibre ‘Leonardo’ is an extremely smooth and flat viscose fibre with a width to thickness ratio of up to 1:40. “This geometry with parallel sides gives the fibre its unique characteristics: In wet laid nonwovens, Leonardo scores with skin friendliness and high liquid storage capacity, typical properties of viscose fibres, which are further improved in Leonardo,” the company said on its website.
In contrast to other viscose fibres, Leonardo also offers high transparency—a property that is much sought after in cosmetic facial sheet masks in the Asian market. Here, transparency not only suggests a high load of moisture, but it also enables a discreet use of the mask even in everyday situations, the company said.
But transparency also offers benefits for other nonwovens products, e.g. for tea bags where the contents can be clearly seen. The possible applications of Leonardo are not limited to nonwovens either: processed into effect yarns, the transparent Leonardo fibre can provide a special look in textiles.
Leonardo—as all viscose specialities from Kelheim Fibres—is made of 100 per cent renewable cellulose and is therefore fully biodegradable. (RKS)
