Development of Coir & Polypropylene Needle Punched Fabrics

Written by: Fibre2Fashion

Of the various known methods of converting textile fibres into a fabric, production of needle-punched fabrics has gained immense popularity among the technical textiles market including geotextiles.

One of the important applications of geotextiles is erosion control. Soil erosion is the process of transportation of soil particles from their original position by the drag forces created by falling or running water and blowing wind. According to the newsletter science daily, China and India are losing 30 to 40 times faster than the natural replenishment rate. Therefore, it is essential to control soil erosion. The effective way of controlling the soil erosion is to have the dense vegetation growth. However, in certain areas, especially in newly formed man made slopes, it is not possible to have the densely grown vegetation as any new vegetation growth may be washed out before the roots are firmly entrenched. An effective alternate solution is required until the vegetation growth. One of the solutions is the use of artificial systems like geotextiles.

Since the application is a temporary one, the geotextiles made from natural fibre will be a good choice. However, the natural fibres will be subjected to degradation by microorganism present in the soil, which may reduce its original strength within short time but as it degrades, it can act as manure, which will help in quicker growth of vegetation. If a small proportion of synthetic fibre is blended with the natural fibre, the loss in strength of the geotextiles can be compensated. To read more,
