COMPOSITE TEXTILE STRUCTURES FOR PARIETAL DEFECTS

Abstract

Composite textile structures designed to repair parietal defects, were obtained from monofilament yarns of polyester, polylactic acid and multifilament of Ag and high-density polyethylene, on Shima Seiki SIG 123 knitting machine of E8 gauge. The mass of composite structures after finishing is placed between 29.6 g/m2 and 158.9 g/m2. The textile structures from: PES/ Ag and PP/ Ag belong to low elastic modulus meshes (10.9MPa). The anisotropy is suitable for all variants of textile structures with values less than 1.00. The best value of cell proliferation indicator - MTT (1,771) was recorded at the PES/PLA composite textile structure which is higher than the control value of 1.22; this structure also shows the lowest value of cell death indicator - LDH (0.405), but which is higher than the control value of 0.370; cell viability has a very high level in this structure (144.83%), higher than that observed in control cells (HT 29 cells in culture) of 100%.
