Canvas tips

A thicker cotton or linen fabric. Named after its original use for sails. In general, plain weaves are used, and a small number of twill weaves are used. The warp and weft yarns use multiple strands. Canvas is usually divided into rough canvas and fine canvas. Crude canvas, also known as canopy cover fabric, is commonly used in the knitting of 4 to 7 strands of No. 58 (10 briskets). The fabric is fast and durable, and has good waterproof properties. It is used for covering of automobiles and open storage, as well as outdoor tents. The fine canvas warp and weft yarns are generally 2 strands of 58 to 6 strands of 28 (10 bristle/2 to 21 briskets/6) for the production of protective garments and their supplies. After dyeing can also be used as shoes, travel bags, backpacks and other fabrics. In addition, there are rubber canvas, fire-retardant, radiation shielding canvas, paper machine canvas.
1, canvas yarn:
In short, yarn refers to the degree of coarseness of the yarn. China's current general term is "English style": 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 is represented in the English system is the English alphabet "S" The representation of the single yarn is: 32 single yarns - ----- Expressed as follows: The representation of 32S strands is: 32 strands (two strands) are both: 32S/2, 42 strands and 3 strands are both: 42S/3.
2, canvas density:
Density of canvas fabrics is calculated in metrics, which refers to the number of arranged warp and weft yarns within 10cm. The size of the density directly affects the physical and mechanical indicators such as the appearance, feel, thickness, strength, flexural resistance, air permeability, abrasion resistance, and thermal properties of the fabric. At the same time, it also relates to the cost of the product and the size of the production efficiency.
3, canvas weight:
Weight: refers to the weight in grams of a square meter of fabric. Woven canvas fabric with "Oz" "An" or "OZ" knitted canvas in general weight (g/m2)
Its conversion is 1 ounce is equal to 28.375 grams but in the weighing machine is generally 28.35 grams, with the yarn count and fabric density, the thicker the yarn, the thicker the cloth, the greater the weight of the gram.
This is not related to the density of the fabric, but the ounces are used on relatively thick fabrics. For example, denim canvas must be in ounces. In fact, you can also understand the relatively coarse ounces of yarn. But now it is generally used in denim and canvas.
4, canvas width:
Width: refers to the width of the canvas in the latitude, commonly used in the international "inch" or """, such as 47 ". In the country commonly used "cm" or "cm" said, such as "120cm."
Inch and centimeter conversion formula: 1 inch = 2.54 cm canvas Calculate the width of the common conversion form:
Inches cm General usage 36" 91.44 90cm
47"119.38 120cm
63" 160.02 160cm
