Excuse me, what is nonwoven fabric? What is felt cloth? Is there a difference between non-woven fabric and felt cloth? Weight? Width?
The difference between felt and non-woven fabric is that felt is generally pure wool, while non-woven fabric is needle-punched by chemical fiber. The gram value depends on the weight per square meter. The width depends on the width needed by the bureau. Generally, the width of non-woven fabrics is about 2 meters. Felt is generally a square of1m×1m.
