Concept:
Felt is a non-woven fabric produced by matting, condensing, and pressing fibers together. Wool is uniquely suited for this due to its microscopic scales.
Step 1: Ordering the manufacturing stages:
• Opening and Cleaning (A): Raw wool is opened up and impurities are removed.
• Carding (D): Fibers are disentangled and aligned into a thin web.
• Web Bonding (B): Layers of carded webs are stacked and consolidated.
• Fulling (E): The application of heat, moisture, and agitation causes the wool fibers to shrink and interlock.
• Brushing and Shearing (C): Finishing processes to smooth the surface and achieve uniform thickness.
Step 2: Conclusion:
The logical flow from raw material to finished non-woven fabric is A-D-B-E-C, which corresponds to option (1).
