Sontora is produced as which fabric structure?

• A. Spun-laced fiberweb, heat bonded
• B. Woven satin
• C. Knitted jersey
• D. Nonwoven felt

Answer: (A)

Sontara is a nonwoven fabric made by the spunlace process. A fiberweb is formed and then bound together by high‑pressure water jets that mechanically entangle the fibers—this hydroentanglement creates a soft, fabric-like sheet without weaving or knitting. Some versions are then heat bonded to boost strength and stability, hence the description “spun-laced fiberweb, heat bonded.” Woven satin and knitted jersey are produced by interlacing yarns and loops respectively, which is not how Sontara is made. Felt is produced by matting fibers through heat and agitation, not by hydroentangling a fiberweb.
