Polyester fibers are resistant to which of the following conditions?

Extreme heat
Brittleness
Mildew and sunlight
Elasticity loss

The correct answer is: Mildew and sunlight

Polyester fibers are known for their exceptional resistance to mildew and sunlight, making them a popular choice in various applications, particularly in outdoor textiles and clothing. This is primarily due to their chemical structure, which is less vulnerable to fungi and the degrading effects of UV light compared to natural fibers. As a result, fabrics made from polyester tend to retain their appearance and functionality for longer periods when exposed to these conditions, which is important in maintaining fabric integrity and aesthetics. Understanding the resilience of polyester to mildew and sunlight is critical for various industries, including fashion, home textiles, and outdoor gear production. This characteristic not only impacts the longevity of the products but also informs care recommendations and application suitability. In contrast, while polyester has certain strengths, it does not inherently resist extreme heat, may become brittle under certain conditions, and can face issues with elasticity loss over time, particularly if subjected to excess heat during processing or care. These factors are not typical strengths of polyester, highlighting the significance of its resistance to mildew and sunlight in comparison to the other options presented.
