The present invention relates to the field of C08L23/06, specifically the preparation and application of efficient, green, pollution-free ultra-high molecular weight polyethylene fibers. The present invention provides an efficient, green, and pollution-free preparation process for ultra-high molecular weight polyethylene fibers. Through extrusion treatment in twin-screw and single screw extruders, further dissolution and homogenization are achieved, improving production efficiency while avoiding spinning instability and fiber surface defects, ensuring product quality, strength, and toughness; By using ultra-high molecular weight polyethylene in combination with specific biobased biodegradable materials and employing a specific dispersion process with the use of solvents, the spinnability and degradability of the fibers are improved, avoiding the problem of product quality degradation caused by the aggregation of spinning solution on the spinneret without spinning. The ultra-high molecular weight polyethylene fibers prepared by this process have high strength, toughness, and degradability, especially suitable for the actual processing and use requirements of ropes, cables, fishing nets, and various fabrics.
