This invention discloses a high abrasion-resistant textile yarn and its production process, belonging to the field of textile yarn technology. The process includes the following steps: Step S1: Abrasion-resistant filament and cotton yarn are twisted together at a distance of 2-3 mm, following a Z-twist direction and a twist of 110-115 twists / 10cm on a ring spinning machine, and then wound to obtain a composite yarn; Step S2: Another abrasion-resistant filament and the composite yarn are combined at a speed of 250-255 m / min using a doubling device, and then twisted on a doubling machine following an S-twist direction and a twist of 50-55 twists / 10cm, so that the abrasion-resistant filament is tied to the composite yarn in the opposite direction, resulting in a high abrasion-resistant textile yarn. This invention uses two abrasion-resistant filaments intersecting to form a mesh structure, with cotton yarn wrapped within it as the core yarn. The resulting high abrasion-resistant textile yarn has a low twist, retaining the softness of the internal cotton yarn while significantly improving the abrasion resistance of the textile yarn.
