AB  - High-performance polyethylene fibers, renowned for their superior attributes 
      encompassing a high strength, modulus, and lightness, are conventionally 
      manufactured through the gel spinning method. However, this method is encumbered 
      by several drawbacks, including the requisite application of a separate process 
      to eliminate solvents from the fibers and the utilization of chemicals 
      deleterious to both the environment and human health. Alternatively, the adoption 
      of the melt spinning method presents a cleaner and environmentally friendly 
      approach to attain high-performance fibers. In the present investigation, 
      high-density polyethylene (HDPE) fibers were produced employing the melt spinning 
      method. After the spinning process, strategic orientation procedures were 
      implemented to enhance the crystallinity of the spun fibers. As a concluding 
      step, seeking to elevate the overall performance of the oriented spun HDPE 
      fibers, a cross-linking treatment was applied via UV irradiation. Notably, this 
      study pioneers the incorporation of polyhedral oligomeric silsesquioxane (POSS) 
      hybrid nanoparticles into HDPE during melt spinning, presenting a novel 
      advancement aimed at further enhancing the mechanical properties of oriented HDPE 
      fibers during UV irradiation. For this purpose, two distinct types of POSS, 
      namely octavinyl POSS (OVPOSS) and methacryl POSS (MACPOSS), both having 
      unsaturated double bonds capable of participating in the network structure of 
      oriented HDPE spun during UV cross-linking, were used. The thermal, 
      morphological, and mechanical properties, as well as the crystal structure of 
      samples with and without POSS molecules, were investigated. The mechanical 
      properties of the fibers exhibited higher values in the presence of OVPOSS. The 
      incorporation of OVPOSS and MACPOSS resulted in a noteworthy improvement in the 
      material's tensile strength, exhibiting a marked increase of 12.5 and 70.8%, 
      respectively. This improvement can be attributed to the more homogeneous 
      dispersion of OVPOSS in HDPE, actively participating in the three-dimensional 
      network structure. After orientation and UV irradiation, the tensile strength of 
      HDPE fibers incorporating OVPOSS increased to 293 MPa, accompanied by a 
      concurrent increase in the modulus to 2.8 GPa. The addition of POSS nanoparticles 
      thus yielded a substantial improvement in the overall performance of HDPE fibers.
