Abstract: To enhance moisture absorption, abrasion resistance, and to maintain the soft feel, glossy appearance, and colorfastness of finished products, acrylic, modal, and wool were blended in a specific proportion based on fiber characteristics. Drawing from blending experience, the paper discusses the difficulty of spinning acrylic and blending a small amount of wool. By controlling temperature and humidity in a small area, optimizing the fiber blending process, and managing key technological parameters at each stage, production stability was ensured and the quality of semi-finished products improved, thereby enhancing yarn quality. The results indicate that the 14.8 tex acrylic/modal/wool compact-spun yarn achieves a high-quality standard, effectively elevating product grade and boosting market competitiveness.
