A slipcover (also called loose cover) is a fitted protective cover that may be slipped off and onto a piece of upholstered furniture. Slipcovers are usually made of cloth. Slipcovers slip on and off; they come fresh and may be removed for seasonal change, cleaning, moving, or storage. Slipcovers are sometimes defined as "clothing for furniture."
The plastic kits and covers are mostly made of synthetic polymers like polythene, and tires are manufactured from polybutadienes. [1] However, due to the environmental issues created by these synthetic polymers which are mostly non-biodegradable and often synthesized from petroleum, alternatives like bioplastics are also being considered.
Polyethylene was first synthesized by the German chemist Hans von Pechmann, who prepared it by accident in 1898 while investigating diazomethane. [12] [a] [13] [b] When his colleagues Eugen Bamberger and Friedrich Tschirner characterized the white, waxy substance that he had created, they recognized that it contained long −CH 2 − chains and termed it polymethylene.
Olefin fiber is a synthetic fiber made from a polyolefin, such as polypropylene or polyethylene.It is used in wallpaper, carpeting, [1] ropes, and vehicle interiors. Olefin's advantages are its strength, colorfastness and comfort, its resistance to staining, mildew, abrasion, and sunlight, and its good bulk and cover.
A duvet cover may or may not have a fastening, known as a closure. Examples of closures include buttons, plastic clasps, zips, and ties. If the duvet cover does not have a closure it can be known as flat, flap or envelope. In the Nordic countries, duvet covers have openings for the hands in the corners, making it easier to change the duvet ...
HDPE is known for its high strength-to-density ratio. [4] The density of HDPE ranges from 930 to 970 kg/m 3. [5] Although the density of HDPE is only marginally higher than that of low-density polyethylene, HDPE has little branching, giving it stronger intermolecular forces and tensile strength (38 MPa versus 21 MPa) than LDPE.
