History

Which textile property determines successful mechanical reeling from silkworm cocoons?

A)Tenacity under heated water
B)Creep resistance at low humidity
C)Elastic modulus after degumming
D)Breaking strength after dyeing

💡 Explanation

Successful reeling requires the cocoon's fibroin proteins to untangle into a continuous strand under heat, relying on tenacity; this water weakens the intermolecular bonds. Therefore, reeling works, because high fiber tenacity under heat prevents fiber breakage, rather than relying on room temperature creep resistance.
