Abstract

Adhesive-free artificial turf comprises a base fabric (1) and grass tufts (2) woven thereon. Each of the grass tufts (2) comprises 2-16 turf fibers. The base fabric (1) comprises warp yarns (11) and weft yarns (10). The warp yarns (11) comprise first warp yarns and second warp yarns separated by a space therebetween. The first warp yarns comprise 1-6 first warp lines (110), and the second warp yarns comprise 4-7 second warp lines (111). Middle portions of the grass tufts (2) are woven and interlaced with the 1-4 weft yarns (10) along an extension direction of the warp yarns (11), and two ends of the grass tufts (2) respectively extend out of the base fabric (1) on the same side. Any two adjacent grass tufts (2) in a row of grass tufts (2) extending along an extension direction of the weft yarns (10) on the base fabric (1) are separated by a space having a width of 3-5 warp yarns (11). Any two adjacent grass tufts (2) in a column of grass tufts (2) extending along the extension direction of the warp yarns (11) on the base fabric (1) are separated by a space having a width of 4-7 weft yarns (10). A space between any two adjacent rows of grass tufts on the base fabric (1) has a width of 1-2 weft yarns (10). The adhesive-free artificial turf has advantages of favorable breathability and drainage, and strong adhesiveness.
