1, canvas yarn support:
In short, the yarn count refers to the thickness of the yarn. China's current general-purpose "English" type: one pound (454 grams) of heavy cotton yarn (or other component yarn), the length of 840 yards (0.9144 yards / meter) When the yarn has a fineness of one. If a pound of yarn, its length is 10 × 840 yards, its fineness is 10, the representation of the yarn count. The English symbol is the English letter "S". The single yarn is expressed by: 32 single yarns -- ----- is expressed as: 32S strands are represented by: 32 strands (two twists and turns) are: 32S/2, 42 sticks and not only: 42S/3.
2, canvas density:
The calculation unit of canvas fabric density is in metric, which refers to the number of warp and weft yarns arranged within 10 cm. The density directly affects the appearance, feel, thickness, strength, folding resistance, breathability, wear resistance and thermal insulation properties of the fabric, and it also relates to the cost and productivity of the product.
3, canvas weight:
Gram weight: refers to the weight in grams of a square meter of fabric. Woven canvas fabric with "ounce" "An" or "OZ" knit canvas is generally used in grams weight (g / m2)
Its conversion is 1 ounce equal to 28.375 grams, but it is generally 28.35 grams on the cloth machine, which is related to the yarn count and the warp and weft density of the fabric. The thicker the yarn, the thicker the cloth and the greater the weight.
This has nothing to do with the density of the fabric, but the ounce is used on thicker fabrics. For example, denim canvas must be in ounces. In fact, you can also understand that the yarn is woven in thicker ounces. But now it is generally used in denim and canvas.
