Optimization and Biodegradability of High-Strength Polyamide Fiber Process
Year: 2025
Type: article
Abstract: High-strength polyamide fiber is a commonly used polymer material, but its degradation is difficult and has obvious impacts on the environment. Therefore, the study proposes to optimize the production process of high-strength polyamide fibers by combining composite titanium dioxide with biodegradable additives. The results showed that after optimizing the production process, the weight loss of the sample after 125 days of soil degradation treatment could reach 18.583%. The experimental samples began to degrade at 400°C, and the residual mass of all samples was less than 2%. After adding composite modified titanium dioxide and biodegradable additives, the tensile strength slightly decreased, and the toughness also slightly decreased. After soil degradation treatment, the macromolecular chains of the optimized sample underwent significant changes, and the number of high-polymer molecules was decomposed into various short chain macromolecular polymers. After optimizing the production process, the biodegradation level of high-strength polyamide fibers significantly increased, and their natural degradation rate significantly accelerated. The mechanical properties of high-strength polyamide fibers only slightly decreased. The optimized production process for high-strength polyamide fibers can effectively improve the degradation level of such products and increase their application scope.
