← HistoryWhich 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.
