Founded in 1956, Calvo Izquierdo S.L is a family-owned company devoted to the design and manufacture of bandages and textiles for the human health industry, mainly cohesive bandages.
Cohesive support bandages are a kind of bandages that are able to adhere to themselves, but not to skin or clothes. They are generally used by professionals of the sanitary sector, for fixing dressings and immobilization splints on different parts of the body, or as protective bandages in sports playing.
Carrying a bandage can be comfortable when there is no humidity. However, the microclimate in contact with the skin should be dry and pleasant, not only to abide by the treatment instructions, but also to avoid the feeling of heat, friction between the skin and the bandage, and injuries and skin diseases. Friction increases with humidity which in turn increases the risk of skin irritation and the formation of blisters.
The persistence of a humid microclimate can also promote certain skin diseases and injuries. It aggravates when patients must wear bandages for long periods of time, as occurs with cohesive supporting bandages. For this reason, the possibility of conferring cohesive bandages with antimicrobial and hydrophobic properties, without loosing breathability, has become of great interest for the company Calvo Izquierdo S.L.
Current solutions are based mainly in the use of chemical surface treatments and/or synthetic fibres, which can modify the final performance and the feel to touch of the bandage, reducing patient/user comfort and wellbeing.
Overall VENDA NATU-haft objectives
VENDA NATU-haft aims to change the landscape of cohesive bandages by introducing a novel antimicrobial and hydrophobic cohesive bandages based on natural fibres and produced by an innovative manufacturing process that incorporates the Multiplexed Laser Surface Enhancement (MLSE). MLSE is able to produce surface modifications at nanoscale, providing with functional properties without significant modification of material appearance. Our new cohesive bandage will offer the following benefits to the end-users:
- Hydrophobic and antibacterial products, thus reducing the possibility of infections.
- Due to the elimination of conventional synthetic fibres and coatings, the bandage will be breathable, maintaining its original performance.
- Very kind to skin improving wearing comfort unlike current solutions that are not 100% based on natural fibres.
