Mechanical and in-use properties of nonwoven fabrics made of bicomponent microfilament PET/PA fibers

Abstract

As nonwovens have advantages like low cost and tunable properties, their implementation to apparels can create advantages. Weakness of nonwoven fabrics for apparel applications arises from their low mechanical properties and drape. However, their properties can be designed by changing the raw materials and production methods. Bicomponent fiber spinning combined with hydroentangling can create advantages by forming microfilaments within the fabric structure, in this regard. Therefore, in this study, nonwoven fabrics of polyester:polyamide 6 (PET/PA6) bicomponent fibers exposed to hydroentangling were tested for their mechanical and in-use properties in order to reveal their usability as apparel fabrics. Results show that mechanical properties of samples reached to a certain level compared to a woven reference fabric. Also, their breathability properties are better than the woven competitor. However, bending and drape properties still require improvements to be used for leisure wear. Apparel models with lower drapes can be selected for nonwoven fabric applications.
