The following is a detailed introduction to PU towels. Combined with its characteristics, uses and common types in the market, it is summarized as follows.

1. Basic concepts and materials

- Material: PU (polyurethane) is a polymer synthetic material. PU towels are usually made of polyurethane foam or coated fabrics and have a soft touch similar to natural leather.

- Name distinction: Unlike traditional cotton or microfiber towels, PU towels focus on quick drying and antibacterial properties, and are commonly used in high-end cleaning or care scenarios.

2. Core features

- Super absorbent: PU's porous structure can quickly absorb water, and the water absorption can reach 5-8 times its own weight, and it is easy to dehydrate after squeezing.

- Antibacterial and mildew-proof: The material itself is not easy to breed bacteria, suitable for use in humid environments (such as bathrooms and gyms).

- Durability: Strong tear resistance, repeated washing is not easy to deform or fall off.

- Environmental protection: Some PU towels use degradable polyurethane, which is more environmentally friendly than traditional PVC.

3. Main application scenarios

- Personal care: face towel, bath towel (especially suitable for sensitive skin, no lint residue).

- Sports cleaning: Wipe gym equipment, absorb sweat after exercise.

- Home cleaning: Kitchen oil stains, mirror polishing, no water marks.

- Industrial field: Cleaning of precision instruments or car interiors (no fiber shedding).

4. Usage and maintenance recommendations

- Cleaning method: Hand wash with neutral detergent, avoid machine washing to cause damage to the foam layer.

- Drying: Dry in the shade in a ventilated place, avoid exposure to the sun to accelerate material aging.

- Lifespan: Normal use is about 1-2 years, if hardening or water absorption decreases, it needs to be replaced.

PU towels have gradually become a popular choice in the high-end cleaning market in recent years due to their functionality and hygiene.
