The characteristics of the canvas are as follows
1. Classification: coarse canvas, also known as tarpaulin, is commonly used in the 58th (10 inch) 4 to 7 strand woven fabric. The fabric is strong and resistant to folding, has good waterproof performance, and is used for covering automobile transportation and open storage. Tent in the wild, farm roller blinds, ships, cargo ships, etc.
Fine canvas warp and weft yarns are generally 2 strands 58 to 6 strands 28 (10 inches / 2 to 21 inches / 6), used to make labor protection clothing and supplies. It can also be used as a shoe, travel bag, backpack, and other fabrics after dyeing.
2. Yarn support: In short, the yarn is the thickness of the yarn. The current Chinese version is still “English”: one pound (454 grams) of heavy cotton yarn (or other component yarn), the length is 840 yards. (0.9144 yards/meter), the fineness of the yarn is 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" Single yarn is expressed by: 32 single yarn -- ----- is expressed as: 32S strands are represented by: 32 strands (two twists and turns) are: 32S/2, 42 sticks and not only: 42S/3.
3. Density: The calculation unit of the fabric density of canvas is in metric, which refers to the number of warp and weft yarns arranged in one square inch. 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.
