Applications Talud
Applications Talud protection Biodegradable non-wovens made from PLA DS Technical Nonwovens, a Belgian company based in Flanders, offers Hortaflex ® , a biodegradable non-woven with or without the inclusion of (grass) seeds. The non-woven is used as agro, geo or horticultural fibre fleece. It can be used as protection against erosion of slopes, battering, and as landscape protection. DS Technical is currently looking for customers interested in further developing the possibilities of this new biomaterial. Soil and root protection The new product is a fully biodegradable non-woven made of PLA fibres and is an answer to various EU regulations (e.g. Kyoto, REACH, reduced use of herbicides, etc.). Originally it was developed for the carpet and technical textiles industry. The production process has been developed in-house. The non-wovens can be offered with different properties: mass per unit area (from 120g/m² up to 1.5 kg /m²), needlepunched or not; structured and calendered. Also tenacity, elongation or other mechanical properties can be varied. Other options are the introduction of additives, lamination, etc. The recently-developed biodegradable non-woven has been used as a base for the new product, and the process has been adapted to include (grass) seeds. First tests show that the results when growing grass were better than when using carpets with a cellulose base, which is a promising sign for other applications. First ideas for possible applications of this product are as a substitute for non-biodegradable products such as the plastics materials that are used to avoid weeds, etc. It offers a good alternative to the existing mulch-mats - certainly where weight becomes important (e.g. roof gardens). On the other hand other applications also appear possible (e.g. the building sector). As a result the company is looking for new applications for this nonwoven, which it would be pleased to develop in collaboration with customers. dirk@dstextileplatform.com 26 bioplastics MAGAZINE [02/07] Vol. 2
