Modified Needle-Punched Nonwoven Based on Blend of Polymer Fibers

The influence of the speed of processing on a special equipment and the content of polypropylene fibers on tensile strength and porosity of modified nonwovens has been studied. The technology of processing needle-punched nowoven fabrics made from blend of fibers with different melting points on a roller calender and a special equipment has been analyzed. At fixed temperatures of the roller in the special equipment the speed of processing affects the tensile strength, but the tensile strength of the modified materials does not depend on the processing speed significantly.
