There has been an innovation need for utilizing fine yarn wastes nowadays. In this study, probability of using yarn wastes in hair interlining industry has been investigated. Information about hair interlining was given and production problems were investigated. It was underlined that by using wastes these problems can be solved environment-consciously. Mass per unit area, breaking strength, elongation at break, fiber blending ratio, circular bending stiffness, and dimensional change of standard and environment-friendly interlinings were tested and comparatively investigated. Consequentially, environment-friendly hair interlinings produced from different yarn wastes have lower shrinkage results. It was found that breaking strength, elongation at break, and circular bending stiffness results of the two fabrics had no remarkable difference. With this study, suitable utilizing area for waste yarns were found and singeing and sizing steps of the production were eliminated. In every sense, this study brings innovations for hair interlining production and makes contributions to the environment.
