Originally, silk bolting cloth was considered as the standard and then quickly replaced by a nylon one, a synthetic fabric. And nowadays, polyester sweeps across the market quickly as it has higher tensile strength, lower elongation and water absorption than silk and nylon. And a simple comparison of these three fabrics is listed below:

Comparison of silk, nylon and polyester bolting cloth
Material	Silk	Nylon	Polyester
Tensile strength	36-75 kg/mm²	41-67 kg/mm²	45-75 kg/mm²
Elongation	15-25%	20-35%	15-30%
Resiliency	54-55%	95-100%	90-95%
Temperature resistance	100°C	100°C	140°C
Water absorption	11%	3.8%	0.4%
