Microfiber sheets are bed sheets made from synthetic fibers such as polyester, nylon, or wood pulp. They are composed of super-thin fibers woven together to create a lightweight and comfortable sheet. Microfiber sheets are less prone to wrinkling and shrinkage compared to natural materials like cotton. They are also more durable than traditional polyester sheets. Microfiber sheets are measured by their denier, which must be less than 1 denier in diameter to be considered microfiber. The weave of microfiber sheets affects their durability and quality. Microfiber sheets with a flat weave are durable, resistant to stains, and repel moisture, while those with a waffle weave are highly absorbent and trap heat. Microfiber sheets are soft and smooth, and they are an affordable option for those who want a velvety texture without paying a high price. They are also low maintenance and available in different varieties. However, microfiber sheets are less breathable than cotton sheets and trap heat more easily.
