The silk fiber should have a degumming process before using biomedical applications. The 25% concentration for Na 2 CO 3 in ethanol solution (80%) as a coagulant chemical with a salt such as LiB 2 (9 M) at a temperature of 98°C for 45 minutes at pH between 6 and 7 should be applied for the degumming process of silk fiber. It has some biomedical applications such as artificial veins and surgical sutures. Its biomedical applications can be studied experimentally by changing manufacturing processes and their process parameters in the future.

In conclusion, orthogonal type 3D woven fabric structures have higher ballistic protection performance compared to conventional 2D woven fabric structures by locking the high-performance yarns used and preventing slippage between layers. It is recommended to use ceramic-structured front plates such as B4C to break armor-piercing bullets, reduce penetration, and absorb a significant portion of their high kinetic energy. UHMWPE, PPD-T, and PBO technical yarns, which have fine yarn counts (between 466 dtex and 933 dtex) can be produced by 1x1 plain woven fabric construction as woven fabric structures (in lamina form). They must have also high warp and weft density values (between 30 warp/cm and weft/cm and 40 warp/cm and weft/cm), orthogonal 3D woven fabric structure, high warp, and weft yarn tension (between 20 cN and 50 cN per warp yarn). Moreover, they must have 160 rpm for their production speed, and multi-layered (between 13 layers and 16 layers in lamina form) in honeycomb (sandwich) geometry. Moreover, the impregnation process can be applied to them with CaCO3, SiO2, PVB, or CNT particles (in the range of 100 nm to 400 nm for particle sizes) with chemicals such as PEG (in the range of 60% to 75% for concentrations), in the range of 80 °C to 160 °C temperatures and between 1 hour and 3 hours. Coating (STF) applications are extremely important and successful for ballistic protection performance at IIIA, III, and IV levels for NIJ standards. Future studies should include orthogonal 3D structured woven fabric applications from UHMWPE, PPD-T, and PBO technical yarns by applying STF technology in this field. They should be also examined comparatively from an experimental perspective.

Two different solvents, acetone and formic acid (FA) were used to dissolve and blend the polymers before electrospinning process. Effect of the solvent on the electrospinability of the blend, final nano/micro fiber morphologies, chemical and thermal properties and antibacterial activities were investigated with SEM, FTIR, DSC, and ASTM 2149 01 Standard Dynamic Contact Conditions. The results revealed that chitosan particles were encapsulated in the as-spun PCL fibers with using acetone as the solvent resulted in reduced antibacterial activities Contrarily, when FA is used as the solvent, CHI and PCL were dissolved and blended very well, and enhanced antibacterial activities were obtained from as-spun PCL/CHI nano/micro fibers.

Later, it is aimed to determine the chemical bond changes between raw samples with ethylene oxide (EtO) sterilization and bio-chemical finishing samples by applying padding process and EtO sterilization processes for all samples with 3-D braiding structures, due to the cross-linking of biocompatible chitosan (CHI) with biological cross-linker glutaraldehyde (GA). The importance of this experimental study is that it is the first experimental chemical analysis in this field in the world scientific study. Padding and EtO sterilization processes were applied on all samples and compared to various technical yarns with 3-D braiding structures thanks to biocompatible CHI. Chemical analysis was interpreted for all samples. It was determined that the applied temperature, co...
