Abstract

Multimaterial textiles are frequently employed to attain a certain function or aesthetic effect. The multimaterial assemblies face recycling limitations due to challenges to sort and separate the component materials. A one-step melt extrusion approach to process two mixed common textile polymers, polyamide 6 (PA6) and polypropylene (PP), into PA6:PP hybrid fibres is reported in this study. PA6:PP hybrid fibres were produced in four different configurations; PA6-50 (50 wt% PA6), PA6-60 (60 wt% PA6), PA6-65 (65 wt% PA6) and PA6-80 (80 wt% PA6). The PP component was sacrificially removed from the hybrid fibres and the resultant PA6 fibre structure was analysed. The SEM images show the development of PA6 microfibres in PA6-50 and PA6-60 hybrid fibres with mean diameters of 0.76 µm and 1.13 µm upon fibre drawing, respectively. In PA6-65 hybrid fibres, the PA6 microfibres were found along with areas where PA6 was encapsulating the PP. Thermal and mechanical properties of the untreated and treated hybrid fibres were also investigated. PA6-60 hybrid fibres were processed into single jersey knitted fabrics and treated to obtain PA6 microfibres fabrics. The bursting strength and wicking properties of the fabric, before and after treatment, were comparatively studied.
