Mm (m/m)
For pure silk fabrics, there is a customary measurement unit, called meter (m/m), and the meter value is used to divide thin fabrics, medium or medium thick fabrics, heavy fabrics, etc. It is generally believed that the fabric below 14m/m is light and thin, the fabric between 14 and 28m/m is medium thickness, and the fabric above 28m/m is heavy fabric.
There is a conversion relationship between the meter (m/m) and the square meter gram weight (g/m2), and the calculation method is:
Mmeter (m/m)=square meter gram weight (g/square meter, g/m2)/4.3056
The fabric is 1 inch wide, 25 yards long, and 2/3 day weight is 1m/m, which is converted into metric system:
1 inch=0.0254 meters, 1 yard=0.9144 meters, 1 day money=3.75 grams
Area: 1 inch x 25 yards=0.0254X0.9144X25=0.58064 square meters
Weight: 2/3 per day=2.5g
1 m meter (m/m)=2.5/0.58064=4.3056 g/m2
Conversion constant=4.3056
This unit of weight is mainly synthetic fiber PP ribbon raw material Water jet looms are not used on fabrics.
Ounces (OZ)
"Ounces (OZ)" is the expression method of gram weight PP webbing manufacturer It is commonly used for woven fabrics such as woolen fabrics and denim fabrics, that is, the number of ounces per square yard of fabric weight, such as 7 ounces, 12 ounces of denim, etc; Essentially OZ/yd2.
Ounce: a unit of mass in the avoirdupois system. English weight measurement unit. One sixteenth of a pound. It was formerly called Yingliang or 唡. The symbol is ounce or oz. One ounce is equal to 28.3495 grams.
"Yard" is a commonly used length unit in the British system. The English word for yard is yard. One yard is equal to three feet.
1 oz=28.3495 g
1 yard=0.9144m
1 square yard=0.8361 square meters
Therefore, 1 ounce/square yard=1 ounce/square yard=28.35/0.836=33.9 grams/square meter
