Novel environmentally-friendly textile protection for maritime antifouling applications based on basalt thread in order to reduce maintenance efforts and costs significantly

Country of Origin: Germany
Reference Number: TODE20191018001
Publication Date: 21 October 2019

Summary

A small German company specialized in knitted clothing and technical textiles has developed a non-toxic textile-based antifouling and protecting material based on basalt thread for maritime buildings, sea-marks, bridges, wind mills and other applications in seawater environment. Efforts and costs are reduced significantly through considerable extension of maintenance intervals. Seeking industrial partners from the maritime sector and maritime operators for technical cooperation agreements.

Description

Maritime buildings and equipment such as bridges, wind mill foundations, piers, harbour foundations, sea-marks, bouys etc. are located in harsh environments and are affected by strong biological and physical influences. In particular algae growth and permanent seawater exposure are causing adverse and harmful damages on their surfaces. In order to ensure function, operability and safety of the equipment regular and periodic maintenance and service measures are required which are cost-intensive with regard to personnel and machine times. The market for maintenance and service products offers a wide range of solutions, mostly special antifouling paints with low durability or harmful synthetic plastic foils and coatings.
To close this gap the company has developed a textile-based protection material made of pure basalt yarn, which is able to extend the regular cleaning and processing cycles significantly. The basalt thread is processed on knitting machines forming and producing a knitted fabric, which is able to cover and enclose the parts of maritime devices under water. The excellent surface properties of this basalt-based material prevent algae growth and extend the operating life in maritime environment significantly.
Basalt thread is a natural raw material and can be used as a draping and elastic knitted construction for tailor-made protective applications with antibacterial, antimicrobial and high-strength properties. The new material protects the environment from contamination by synthetic materials and offers a wide range of further applications for offshore technologies and seawater structures.

Application fields: on and off shore industry, wind mill manufacturers and operators, manufacturers of equipment and devices for harbours (piers, sea-marks, bouys etc.), planners and manufacturers of maritime buildings and bridges

The company is seeking industrial partners from the maritime sector and maritime planners/operators with interest in customized applications. The company offers individual support to realize products and reliable solutions and prefers technical cooperation agreements. Ideas for non-maritime applications or joint projects are welcome.

Advantages and Innovations

-	Excellent antibacterial, antimicrobial and high-strength properties
- Long-term protection of maritime devices
- Reducing the maintenance efforts and budget of maritime companies by 40%
- Sustainable protection of the maritime environment:
Replacing the use of synthetic coating material for antifouling elements
Replacing the use of plastic foils against antifouling
- Why basalt:
 Preventing or clearly deceleration of fouling/vegetation,
 Ecologically harmless/non-toxic, pure basalt, no additives
- Why knitted: Solid, flexible, moldable, excellent drapability
