Also known as a blanket, cover sheet bed, comforter, or duvet cover, a bed cover is a large piece of fabric that sits directly over your bedding as a cover. It is known as a bed cover because the entire fabric wholly covers the bed and everything underneath. A bed cover can be used on its own without bed-sheets if you have a quilted cover for your mattress.
Conclusion
Cotton and cotton blends dominate the market, the most common blend being cotton/polyester. Cotton provides absorbency and a soft hand, while polyester adds durability and wrinkle resistance.[2] Other common fibers used in the manufacturing of bed sheets include linen, silk, Modal and bamboo rayon, lyocell, Microtex or Microfiber, and polypropylene. Polypropylene (olefin) is a hypoallergenic spun-bound material produced at a low cost and typically used in emergency shelters or hospitals as disposable sheeting.
When we use the term bed linen we are generally referring to the sheets used to cover the mattress so that the sleeper is comfortable and the mattress is protected. If blankets or covers are being used a second sheet needs to be used for comfort between the sleeper and the roughness of the blankets. If a continental quilt is being used the top sheet is usually omitted.
Additionally, the cotton-poly blend sheet fabric provides a soft and comfortable sleeping surface. Cotton's natural breathability ensures you stay cool and comfortable all night long, while polyester adds strength and durability to the fabric. This combination creates a luxurious feel that is both comfortable and long-lasting.
