How to calculate the non-woven fabric weight in general

The most commonly used non-woven bag is 75g fabric. For this gram weight, the general fabric factory will make a lot of inventory, because the more used, the more naturally. Here comes the question. Some customers often ask about the price of 80g fabric. There is actually an unwritten agreement. The industry calls it 75g, but outside the industry it is generally called 80g. In fact, we have made non-woven bags for 14 years and have never used 80g of fabric. Unless the amount is relatively large, we will order a certain gram of fabric separately, such as thousands of bags or 10,000 to 20,000. Bags are basically produced with conventional weights. The first point is that the popular name 80g actually refers to 75g non-woven fabric. In the industry, the most commonly used fabric is 75g, then the thicker is 90g, and the thicker is 120g. To the outside of the industry, these three weights actually refer to 80g, 100g, and 120g. Then the weights of 35g, 45g, 55g, 65g are actually useful, but they are relatively not so commonly used. The fabric below 45g is basically not used alone to make bags, because below this gram weight, the fabric is already very thin. Up to 120g, it is rarely used, and the weight of up is basically customized. The cloth factory usually does not make fabrics of more than 120g.


Let’s talk about the key point. How is the weight of non-woven fabrics calculated? In fact, this is very simple. You need to know what the unit of 75 or 90 or 120 is. Then it is easy to understand what these values u200bu200brefer to. I usually say how much the cloth is in g. In fact, its unit is g/square meter. A 75g cloth refers to 75g/square meter. It means that the weight of one square meter is 75g. This is used to measure and distinguish the fabric. In addition to non-woven fabrics, the calculation methods for other Oxford bags, nylon bags, cotton bags, and canvas bags are similar, but the units are different. So how do you calculate it? Now that I know the meaning of this unit, I believe the calculation should be very clear. If you want to calculate the weight of cloth, it is a special measuring tool in the industry. You only need to intercept a small piece of cloth and place it on a sensitive electronic scale to know the weight of the cloth. This is a professional approach. We are open to the public. Generally, there are no professional interception tools. The conventional method is to fold the cloth in half several times, and then cut out some cloth pieces of the same size. Note that the cut cloth pieces must be rectangular or square, so that it is easy to calculate the area of u200bu200bthe cloth. For example, if you cut out 10 pieces of cloth with a length of 10cm and a width of 8cm, and then weigh the weight of 10 pieces of cloth as 6g, then you can know that the original weight of 10X0.1X0.8u003d0.08 square meters or 0.08 square meters of cloth is 6g , Then 6g/0.08 square meter u003d 75g/ square meter. Of course, the more pieces of cloth you cut, the more accurate you cut, and the more accurate the weighed number will be.
