Spunbond

Spunbond was developed in Dresden from 1968 onwards as a substitute product for the natural fibre jute. In 1974, the patent for the production of spunbonded fabric was bought by a plant manufacturer from the Rhineland and further developed. At Innovatec^® it forms the basis for a

wide range of products.

Production of finest nonwovens

Spunbond is a thin continuous filament made of plastic granulate that is melted by heat and then stretched by targeted cold air currents.

The filaments are deposited on a collecting belt and thus combine to form a fleece. Spunbond is based on the meltblown process, but the molten granules are stretched by hot air.

Combination with Meltblown

Spunbonded fabric is often combined with meltblown fabric. This is the case, for example, with medical respiratory masks according to the FFP2 and FFP3 standards
as well as surgical masks.

The outer layer of the masks is made of spunbonded fleece, while
meltblown fleece, which has an even smaller pore size than spunbonded fleece, forms the inner filter layer to ward off bacteria and viruses.
