Development of a Multifunctional Wet Laid Nonwoven from Marine Waste Posidonia oceanica Technical Fiber and CMC Binder

Abstract

A Posidonia oceanica waste marine plant was used to produce a wet-laid nonwoven web for multifunction applications. To study the effect of some parameters related to the web characteristics (sheet weight, binder ratio, and pulp ratio) on the mechanical and physical properties of the web, we used a Box–Behnken design plan with three levels. The diagram of the superposed contours graphic method was used to find the optimum parameters of the process for the application of the Posidonia nonwoven fiber on an insulation field. With the measurement of the thermal conductivity properties using the box method, the results demonstrated that the nonwoven fiber from Posidonia oceanica marine waste had good insulation properties in comparison with other classical natural fibers (hemp, flax) used in the field of insulation with the big advantage of being a natural product.

“…28 In recent years, many authors have investigated the use of POW fibers and cellulosic derivatives as: (i) a filler in potato starch-based films; (ii) a reinforcement in films based on high density polyethylene (HDPE), maleic anhydride grafted polyethylene/HDPE blend, polypropylene, polyvinyl alcohol, and wheat gluten; (iii) an adsorbent for removing metal-complexed dyes, phenols, ortophosphate ions or heavy metals as uranium (VI), chromium (VI), lead (II) (Table 1). [28][29][30][31][32][33][34][35][36][37][38][39][40][41][42][43][44][45][46][47] The improved mechanical and barrier properties, as well as the weakened water trapping ability, exhibited by the biocomposites containing POW fibers suggest a potential use of this waste, as a valuable renewable source for obtaining novel biodegradable materials alternative to the conventional plastics. 48…”

Revolutionizing Sustainable Nonwoven Fabrics: The Potential Use of Agricultural Waste and Natural Fibres for Nonwoven Fabric

“…In another study, a multifunctional wet-laid nonwoven fabric with a 3D structure was prepared from a Posidonia oceanica waste marine plant and carboxymethylcellulose binder. Increasing the number of fibres and binders increased tensile strength due to inter-fibre friction and binding properties [149].…”

Seagrass Leaves: An Alternative Resource for the Production of Insulation Materials

“…Apart from the release of greenhouse gases and unpleasant smells due to natural degradation, the effects of seagrass wrack lying on beaches include the impairment of tourism in the affected areas. Seagrass wrack is therefore removed from the shoreline and disposed of in landfills [ 7 , 8 , 9 , 10 ].…”

“…It should be noted that one of the seagrass types investigated in this study, Posidonia oceanica , which occurs in the Mediterranean area, is subdivided into seagrass fibers and leaves. Seagrass fibers have been extensively studied and are already commercialized as an insulation material [ 10 , 20 , 21 ]. Leaves, however, are less investigated in this regard.…”
