An essential oil is a concentrated hydrophobic liquid containing volatile (easily evaporated at normal temperatures) chemical compounds from plants. Essential oils are also known as volatile oils, ethereal oils, aetheroleum, or simply as the oil of the plant from which they were extracted, such as oil of clove. is a concentrated hydrophobic liquid containing volatile (easily evaporated at normal temperatures) chemical compounds from plants.

The word textile is from Latin texere which means "to weave", "to braid" or "to construct". The simplest textile art is felting, in which animal fibers are matted together using heat and moisture. Most textile arts begin with twisting or spinning and plying fibers to make yarn (called thread when it is very fine and rope when it is very heavy). The yarn is then knotted, looped, braided, or woven to make flexible fabric or cloth, and cloth can be used to make clothing and soft furnishings. All of these items felt, yarn, fabric, and finished objects are collectively referred to as textiles.
Based on original designs by the Canadian designer D.C. Simpson in 1946, variants of the one-piece plastic chair went into production with Allibert Group and Grosfillex Group in the 1970s. They were inspired by the Chair Universal 4867 design by Joe Colombo in 1965, but no patents were filed for a monobloc chair design. Since then, millions have been manufactured in countries including Russia, Taiwan, Australia, Mexico, the United States, Italy, France, Germany, Morocco, Turkey, Israel, India and China. The Monobloc chair is named because it is injection moulded from thermoplastic as one piece rather than being assembled from multiple pieces. Many variations and styles exist but all are designed to allow the chair to be made quickly and cheaply through injection molding. A common thermoplastic used is thermoplastic polypropylene, with the granules being heated to about 220 degrees Celsius, and the melt injected into a mold. The gate of the mould is usually located in the seat, ensuring smooth flow to all parts of the tool.
