Explanation: Indeed, microfiber upholstery is frequently selected for its liquid-repellent properties. This characteristic causes spills to bead up on the surface, facilitating easy cleanup and preventing deep staining.

Explanation: This is incorrect. While microfiber is used in the medical field, its application is typically for enhancing the strength and durability of fabric sheets, not for increasing flammability. In fact, flammability can be a concern with some synthetic fibers.

Explanation: This is incorrect. Microfiber is utilized in products like menstrual pads and diaper inserts primarily for its high absorbency and softness, not for rigidity.

Explanation: Microfiber finds application in a wide range of products beyond apparel, including industrial filters, upholstery, and various cleaning products, owing to its versatile properties.

Explanation: Microfiber's prevalence in athletic wear stems from its exceptional moisture-wicking capability, efficiently drawing perspiration away from the skin to facilitate rapid evaporation and thermoregulation.

Explanation: Car detailers extensively use microfiber for tasks such as removing wax and polishes from paintwork, cleaning surfaces without risk of scratching. Its softness and particle-trapping ability are essential for maintaining automotive finishes.

Explanation: Microfiber towels employed in automotive detailing share a functional similarity with traditional chamois leather in that both materials are capable of leaving surfaces entirely free of lint and dust, thereby ensuring a pristine finish.

Explanation: The long-term economy of microfiber mops, despite potentially higher initial investment, is derived from their extended durability and superior cleaning efficiency. These factors can lead to reduced replacement frequency and potentially lower labor costs.

Explanation: Microfiber cloths are ideal for delicate optical surfaces because they can effectively absorb oily residues and smudges without imparting abrasion or leaving behind lint, thus preserving the integrity of the surface.

Explanation: When microfiber cloths accumulate grit or abrasive particles, they pose a significant risk of scratching or damaging sensitive surfaces, including electronic displays (LCD, plasma).

Explanation: Player feedback indicated significant issues with the microfiber basketballs, including unpredictable bouncing characteristics and a tendency to cause cuts on players' hands, prompting the league's return to leather basketballs.

Explanation: When microfiber upholstery repels liquids, the liquids tend to bead up on the surface. This behavior allows for quick and easy wiping, preventing the liquid from penetrating the fabric and causing stains.

Explanation: This is an accurate definition of non-renewable resources. Petrochemicals, derived from petroleum, are finite and are depleted at a rate far exceeding natural replenishment.

Explanation: This statement is false. Microfiber, being synthetic and derived from petrochemicals, is not readily biodegradable and persists in the environment for extended periods, contributing to pollution concerns.

Explanation: This is accurate. Synthetic textiles, including microfiber products, shed fibers during laundering that enter wastewater systems and ultimately contribute significantly to microplastic pollution in oceans, rivers, and lakes.

Explanation: This is accurate. Microfiber textiles derived from hydrocarbon sources, such as polyester, can be flammable and may emit toxic gases when burned, particularly if they contain aromatic compounds or have been treated with flame retardants or certain dyes.

Explanation: This statement is false. Polyester and nylon microfibers are derived from petrochemicals, which are non-renewable resources. Their synthetic origin means they are not biodegradable and pose environmental challenges.

Explanation: This is incorrect. Microfibers shed from synthetic clothing during washing are a major contributor to microplastic pollution in marine environments, representing a significant portion of the plastic debris found.
