Utilization of recycled fibers in nonwovens has been an attractive issue for researchers considering environmental and economic benefits. In this study blanket trimmings and mechanically recycled fibers were blended and softly needle-punched to be used as interlayers of traditional needle-punched nonwovens. The outer layers from polypropylene, from recycled polyester, from mechanically recycled fibers and the control groups were produced by classical needle-punching at two needle-punch densities. The recycled interlayers consisting of blanket trimmings and mechanically recycled fibers are then fixed by needle-punching again, between the two twin layers of needle-punched nonwovens of those three types of raw materials. Control groups did not include the recycled interlayers. Hence, three layered end products were obtained. Tensile characteristics of the end products were evaluated in terms inter layer ratio of the end products, raw material type of outer layers and needle-punching density through standard test methods. The results were statistically analyzed in SPSS 23.0-One way ANOVA. In the conclusion, blanket trimmings were successfully entangled to the end products as interlayers and it was observed that the strength of the nonwovens decrease with the higher recycled interlayer ratio and increase with needle-punch density.
