Fabric Knowledge Introduction Part One
1. The weight of fabric: g/m3

When you have a fabric that is not engraved enough to weigh in your hand,
All you have to do is cut the fabric into a square.

measure fabric

Then calculated the area (sqm)
Weigh the fabric
Weight divided by area is the weight of the fabric.
Why first measure the weight of the material?
Because we will have some error in the measurement of the longitude and latitude density of the fabric and yarn specifications at the back,
we can use this weight to verify that our density and yarn specifications are correct.

2. The specifications of the filament yarn Unit: Dannier (D)
Filament refers to the silk as long as silk, there are many, polyester filament, nylon filament, acrylic, adhesive filament is also rayon, spandex wire and so on.
Long silk is usually expressed in Dannell (D), defined as: every 9000 meters of sand weight, in the analysis of fabric, you can first pull out 10 yarns from the longitude or latitude, weigh, and then measure the length of 10 sand, weight divided by length to calculate the weight of yarn per meter, and then multiplied by 9000 to get yarn specifications.

3, F.
Each yarn in the description of his specifications is like this, 75D/48f, what is the concept of this 48f?  This 75d yarn is made up of 48 small fibers, the higher the f number means that each fiber that makes up this 75d yarn is thinner, where the less f is the thicker the fiber.
