Note:
1. The denition of the fabric thickness:
Thin (fabric): two layers of the fabric thickness < 0.35mm;
Thick (fabric): two layers of the fabric thickness > 0.8mm;
Regular (fabric): two layers of the fabric thickness ≥ 0.35mm and ≤ 0.8mm.
2. The denition of elastic cloth:
If the cloth, which size is “100mm x 30mm”, is extending to over 106mm under 0.5KG
tension force, then the cloth is dened elastic, otherwise it is inelastic.
3. Hard fabric: such as Jeans, ne canvas, etc.
4. Soft fabric: such as towel, duster, etc.
MORE TIPS
