Which of the following is true about crystalline fibres?

• A. They are always less absorbent
• B. They are generally weaker
• C. They are made from synthetic materials only
• D. They have random polymer arrangements

Answer: (A)

Crystalline fibres are characterized by their ordered molecular structure. This organized arrangement of polymers contributes to their physical properties, including their absorptive capacities. In general, crystalline fibres tend to be less absorbent than their amorphous counterparts. The tight packing of polymer chains in crystalline fibers leads to a reduced amount of space for moisture to be absorbed, making them inherently less efficient in wicking moisture. The other options do not accurately represent the properties of crystalline fibres. For instance, crystalline fibres are often stronger due to their ordered structure, contradicting the notion of them being generally weaker. Additionally, these fibres can be made from both natural and synthetic materials, not exclusively from synthetic ones. Finally, the molecular arrangement of crystalline fibres is not random; it is highly organized, contrasting with the disorder seen in amorphous fibres.
