    Despite the widespread usage and affordability of petroleum-based products, there has been tremendous effort in prioritizing and utilizing biodegradable and environmentally friendly materials. Untraditional natural fibers play a critical role in sustainability studies; however, fibers such as kapok and milkweed are quite expensive compared to other plant-based natural fibers such as cotton and flax. Therefore, it is critical to utilize these untraditional fibers in the most efficient manner that is possible. In this study, short milkweed fiber leftovers collected from the milkweed yarn spinning process were utilized as a filler material inside the needle-punched nonwoven fabrics. For this purpose, short milkweed fibers were blended with hollow polyethylene terephthalate (PET) fibers to develop nonwovens. Three different sets of weight/g fabrics were prepared for both only PET containing and short milkweed/PET blended fibers. Thickness, weight, tensile and bursting strength, thermal comfort, air permeability, and water contact angle measurements were conducted for the samples. Consequently, the thermal resistance of short milkweed/PET blended fabrics with similar weight increased by up to 34% compared to only PET-containing fabrics. Results indicate that valuable short milkweed fibers are suitable for developing nonwoven fabrics with comparable physical properties and superior thermal insulation properties.

    Utilization of poplar fibers in needle punched nonwovens

    The focus of this study is to conduct pioneering research on utilizing poplar seed hair fibers in needle punched nonwovens. These fibers were blended with hollow PET fibers at two different weight ratios to obtain needle punched webs for the first time. The weight, thickness, abrasion resistance, bursting and tensile properties, hydrophobic/oleophilic surface characteristics of the nonwovens are analyzed elaborately. Finally, it has been demonstrated that poplar fiber-containing nonwovens have superior rose oil absorption compared to solely PET nonwoven fabrics. When compared the maximum adsorption capacities, the incorporation of 37.3 wt.% and 21.7 wt.% poplar fiber into PET nonwoven increased the oil absorption by approximately 35 and 24 times, respectively. Although pristine PET nonwoven was able to remove only 16% of MB dye from aqueous dye solution, addition of poplar fiber enhanced the removal process and the solution had been decolorized to nearly colorless. The results indicated that poplar blended nonwoven fabrics treated with NaClO2 show the high-performance removal of MB dye from wastewater, with the increased percentage of 40% and 67% for PET-PO30 and PET-PO60 fabric, respectively. Therefore, developing industrial scale surfaces with non-traditional and sustainable poplar seed fibers, marks a significant advancement for the textile industry.
