Canvas Bag Fabric Density

Canvas Bag Fabric density

The material used in the fabric 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. With the development of society and the progress of science and technology, people invented the plastic bags of this convenient stuff when the bag, also caused a certain degree of environmental pollution problems. Because plastic is a very difficult to degrade the material, a lot of use of plastic bags will cause a lot of environmental problems, many people also called plastic bags white garbage. With the progress of people's environmental concepts, people now have been aware of the issue of environmental protection. Canvas bag more and more popular in people's lives. A small canvas bag, for the big cause of environmental protection made a great contribution to his main use there are several aspects.

With the progress of people's environmental concepts, people now have been aware of the issue of environmental protection. Canvas bag more and more popular in people's lives. A small canvas bag, for the big cause of environmental protection made a great contribution to his main use there are several aspects.

First of all, canvas bag can reduce the use of plastic bags for people, and because it is made of cloth materials, so you can re-use. Especially in the supermarket when shopping, many people used to buy a large bag, after the use of readily thrown away, resulting in waste does not say, but also on the environment pollution. But after the use of bags, you can repeat the use of many times, greatly reducing the degree of dependence on plastic bags, the protection of the environment is very good. Second, this bag is a safer material. Compared to plastic bags, the bag is relatively safe, the impact on food is relatively small, so many people are now more and more use of bags to shop. Third, the production of canvas bag than the plastic bag to be a lot of fine, so many businesses also produced a lot of fine bags to the customer, on the one hand made a contribution to environmental protection, but also to the customer to provide a convenient.
