What is a distinctive property of olefin fibers?

1. Absorbs moisture easily

2. Highly resistant to chemicals, mildew, and microorganisms

3. Good thermal insulation

4. Soft texture comparable to cotton

The correct answer is: Highly resistant to chemicals, mildew, and microorganisms

Olefin fibers, also known as polypropylene fibers, are characterized by their unique resistance to a variety of environmental factors. This distinctive property includes a high resistance to chemicals, mildew, and microorganisms. As a result, olefin is often used in applications where durability and cleanliness are important, such as indoor and outdoor furnishings, automotive interiors, and some types of clothing. In terms of chemical resistance, olefin fibers do not absorb water, which contributes to their mildew resistance. This makes them suitable for use in humid environments where mold and mildew might otherwise be a concern. The lack of moisture absorption also limits the growth of microorganisms, making olefin a practical choice for products that require regular cleaning or that will be exposed to various elements. This combination of characteristics makes option B the accurate answer regarding olefin fibers, setting them apart from other types of fibers that may be more susceptible to mildew and bacterial growth.
