Naturally woven cottonized jute mats were acquired from local shops in Coimbatore, Tamilnadu region, India. as produced by Usha Corporation Limited (UCL). These mats are normally obtained in low areal weight for possible coupling with cotton in textiles, therefore in comparable thicknesses. MMTK10 (Montmorillonite) nanoclay (surface area 220–270 m²/g) was supplied by Sigma–Aldrich (St. Louis, MO, USA) and Egg Shell Powder (ESP) was mashed in dimensions in the order of 30 microns, along the lines of what performed in [24 (link)]. The prepared composite contains the jute fabric mat with three slightly different areal weights (44, 45 and 46 g/m²). Unsaturated polyester resin was used as the matrix. Methyl ethyl ketone peroxide (MEKP) was used as the catalyst and cobalt naphthenate as the accelerator; all those chemicals were supplied by Aishwarya Polymers, Coimbatore, Tamilnadu State, India.
