1. Density The density of a woven fabric refers to the number of yarns placed in a unit length in the vertical and horizontal directions of the fabric. The density of the fabric has a great influence on its wearing properties such as strength, elasticity, hand feel, body bones, air and moisture permeability of the drip tape, and the rate of breakage during the weaving process. If the warp and weft density is high, the crocheted belt will appear tight, thick, stiff, wear-resistant and firm. If the density is low, the crocheted belt will be thin, soft, and have good permeability. If the thickness of the warp and weft yarns of the same density of the crochet belt is different, the actual density of the anti-skid belt will be different. When comparing the tightness of crochet belts of different thickness yarns, it is necessary to consider the fineness and density of warp and weft yarns together. This is the tightness, and the tightness is the relative density. It is the diameter of the warp (weft) yarn against the adjacent two. The ratio of the uniform center spacing of warp (weft) yarns is indicated by the percentage of hundred rubber bands. The fabric with too much tightness in the warp and weft directions increases its rigidity, decreases its wrinkle resistance, increases its resistance to flat abrasion, decreases its resistance to abrasion, and has a hard hand feel; while the tightness is too small, too loose, and lacks body bones.
2. Warp tightness, latitude tightness, total tightness. The warp tightness, weft tightness, and total tightness of crocheted belts are mutually restricted; when the total tightness is certain, the warp tightness and weft The fabric is tightest when the tightness is roughly equal, and the rigidity is the greatest; and the tightness in the warp direction is greater than or less than the tightness in the weft direction, which makes the fabric soft and draped. The different values of the warp and weft tightness also affect the warp and weft breaking strength of the fabric.
3. Arrangement The arrangement of crocheted belts is different, and the weaving patterns or textures are different, such as the grains of the plain weave arrangement, the diagonal textures of the twill arrangement and the floating long lines of the satin weave arrangement. The arrangement not only affects the appearance and texture of the crochet belt, but also affects the fabric style and the connotation quality of the fabric that people feel. For example, plain weave fabrics have firm texture; satin weave fabrics have a smooth surface, luster and soft texture.
