Canvas Bag Materials used

Canvas bag material used canvas fabric density calculation unit in metric meter, refers to 10cm within the number of latitude and longitude yarn arrangement. The size of the density directly affects the appearance of the fabric, feel, thickness, strength, bending resistance, permeability, wear resistance and thermal performance and other physical and mechanical indicators, and he also concerns the cost of the product and the size of the production efficiency. Canvas bag material density direct measurement method is by virtue of cloth or fabric density analysis mirror to complete. Fabric density analysis mirror scale length of 5cm, under the analysis of the lens, a long strip of glass plate engraved with a red line, in the analysis of fabric density, the movement of the lens, the glass on the red line and scale on the red line at the same time Root yarn, as a starting point, while moving the number of yarn edge of the number of yarn, until the 5cm scale line for this. The number of yarns output is multiplied by 2, which is the density of 10 cm fabric. When the number of yarns in the number of points, the center of the two yarns should be the starting point, if the number to the end, more than 0.5, and less than one, should be 0.75 basis; if less than 0.5, then According to 0.25 operator. Fabric density should generally be measured 3-4 data, and then take the arithmetic mean for the determination of the results. Canvas bag making materials and requirements:

1, canvas yarn count: yarn branch In short, that is, the degree of yarn thickness, China is currently common or "British" that: one pound (454 grams) of heavy cotton yarn (or other ingredients yarn), canvas bag length For 840 yards (0.9144 yards / m), the fineness of the yarn is one. If a pound yarn, its length is 10 × 840 yards, the fineness is 10, the yarn branch of the representation of the British-style symbol is the English letter "S" single yarn that is: 32 single yarn - ----- said: 32S shares of the line is: 32 shares (two and twist) both: 32S / 2,42 3 and twist both: 42S / 3.

2, canvas bag canvas density: canvas fabric density calculation unit to the meter, refers to 10cm within the number of latitude and longitude yarn arrangement. The size of the density directly affects the appearance of the fabric, feel, thickness, strength, bending resistance, permeability, wear resistance and thermal performance and other physical and mechanical indicators, and he also concerns the cost of the product and the size of the production efficiency. Canvas bag manufacturers canvas bags in our lives in a wide range of applications, depending on the following advantages:

1. Canvas bag material and cotton bag material as cotton are taken from the natural, said the above, of course, environmental protection;

2. Environmental canvas bag, the biggest cost is the fabric, and some non-woven bags are environmentally friendly ink, generally not to save that money and cut corners (unless the manufacturer to Mongolia), said here can also be called Be environmentally friendly;
