Which property of silk affects its care requirements?

The choice of weakness when exposed to sunlight as the property of silk affecting its care requirements is accurate because silk is particularly sensitive to UV light. This exposure can cause the fibers to weaken and degrade over time, leading to loss of strength and deterioration of color. Therefore, care for silk garments often involves precautions to avoid direct sunlight, ensuring that items are stored properly and not displayed in bright light for extended periods. This means that appropriate care and storage methods are essential for maintaining the longevity and appearance of silk textiles.

In contrast, the absorbent nature does affect how silk interacts with moisture but does not dictate care requirements to the same extent as its sensitivity to sunlight. Low resilience pertains to how well silk maintains its shape, while high elasticity refers to the ability of the fabric to stretch, neither of which plays a crucial role in the specific care practices necessary to protect silk from light damage.
