Preparation and performance study of covered yarn fabric based on double-weft yarns with rigid and flexible alternating texture

Purpose This paper aims to study the cut resistance of fabrics woven from covered yarns with different structures and a rigid-flex alternating structure. Design/methodology/approach Effects of covered yarn structure on fabric mechanical and cut-resistant properties were systematically investigated through engineered yarn and fabric architectures. Using single-weft and double-weft yarn strategies (A/D ratios: 1:1, 2:1, 3:1), four fabric types were fabricated. Analysis focuses on yarn guide distance, yarn structure and double-weft ratio effects on tensile and cut-resistant properties. Findings An optimal yarn feed distance (5–13 cm) increases yarn breaking force by 11%–36%, varying with outer wrapping material. Nylon (PA6) outer yarn fabrics showed plastic deformation; stainless steel outer yarn fabrics showed brittle fracture. All double-weft ratio fabrics achieved ANSI/ISEA 105-2016 A6 cut resistance, improving 3%–23% over single yarn structure fabrics. Originality/value This study provides theoretical support for the design of cut-resistant fabrics from the perspectives of both yarn structure and fabric structure.
