Non-woven fabrics or non-woven fabrics do not refer to specific fabrics, but a category, that is, words such as "vegetables" and "fruits. PP spunbond non-woven fabric, PP is the abbreviation of polypropylene, spunbond is a process of fabric, the fabric produced is the kind of fabric commonly used in supermarket shopping bags.

nonwoven algorithm:

1. Calculate the thickness of the fabric

(A) When calculating the thickness of the fabric, some take the square gram weight, that is, the weight per square meter to measure the thickness of the fabric. The thickness calculated by this method is more accurate, the general market can do 10G300G, beyond this range, generally not PP non-woven fabric.

(B) The thickness of the cloth is directly measured with a caliper. The thickness is 0.1mm × 1.0mm. The ratio of this thickness is basically the same as the above square gram weight.

2. Calculate the width of the cloth.

Due to convention, the width is generally expressed in feet (inch), one foot is about 2.54 centimeters (cm), and it is also commonly used in industry ( ) , for example, 63 inches, the width is 160.02cm, and the 160 is 1.6m. Domestic manufacturers generally according to the width of the production equipment to determine the general specifications of 1.6 meters, 2.4 meters, 3.2 meters, because the early non-woven manufacturers only 1.6 meters of equipment, now non-woven 1.6 meters has become the most commonly used wide specifications.

3. Calculate the length of the cloth.

For non-woven fabric manufacturers, the length can actually be arbitrary, but the commonly used length is determined by factors such as suitable processing, convenient billing and production. Due to the different specifications of the square gram weight of non-woven fabrics, and the length units are meters and yards, the commonly used constants are 100 meters, yards or 300, 500, 1000, 2000, etc.

As mentioned above, due to industry practice, equipment, and equipment, when calculating the length of the cloth, the yardage unit (Yard or Y) is used. 1Y is approximately equal to 0.9144M. The above calculations often use conversion, so the unified unit is the key to the calculation. With the above three parameters of thickness, width and length, you can calculate the results you want at will. The algorithm of any cloth and paper is also calculated according to the above standards, but there are some similarities.
