The fiber is developed for high loft nonwovens. The fiber design has the following advantages over its predecessors and competing bicomponent fibers:
• The fiber network after oven is rigid and strong and results in a larger void space per cm³. The space within the structure can provide air for insulation purposes, a reservoir for fluids, a large surface area, bulk for stabilization or filling as well as many other applications.
• The fiber has a higher temperature resistance, thereby lowering the thermal shrinkage of the fabric.
• The ES-Delta II combination of PE (sheath material) and PP (core material) makes it an ideal and environmental binder fiber avoiding the use of adhesives. It bonds to all synthetic and natural fibers.

ES-Delta is manufactured and marketed in a range of dtex in order to enable various applications. A large denier (dtex) fiber will increase the compression resistance or stiffness, whereas a low denier fiber will create a tighter network.

Applications
ES-Delta II fibers can be used with advantage in hygiene acquisitiondistribution layers, filters, household products, medical products and other air-through (oven) bonded products.
