Let's talk about the Microfine polyester.

Ultrafine polyester fiber is a type of fiber made from polyester through high-tech processing. The diameter of this fiber is dozens of times finer than that of ordinary polyester fibers, with a large surface area and loose structure. Therefore, it has the characteristics of lightweight, soft, breathable, moisture absorption and quick drying, as well as high strength and durability

The main materials of BrilliaTech's BT4005, BT4004, and BT4003 are microfiber towel, with a soft feel, strong water absorption ability, and simple operation.
