The document discusses different types of materials used in manufacturing including textiles, metals, woods, and plastics. Textiles come from natural fibers like silk, wool, linen, and cotton or manufactured fibers like polyester, nylon, and rayon. Metals are divided into ferrous metals containing iron like steel and non-ferrous metals without iron like copper. Woods are classified as softwoods from conifers, hardwoods from deciduous trees, or manufactured boards. Plastics are polymers and include thermoplastics that can be remelted like polyethylene and thermosets that set permanently like polyester resin.

1. The fibres used in textile come from two sources: natural ones from plants and animals and manufactured ones, mainly from oil.Natural: silk filament, wool staple, linen, cotton, jute, and hemp. Manmade: terylene, polypropylene, acrylic, nylon, polyester, viscose and rayon There are two types of metal: ferrous metals and non- ferrous metal.Ferrous (contains iron): steelNon-ferrous (does not contain iron): copper - Metal occur naturally in the found either as ores or the metal themselves. Woods are classified into three main groups, softwoods, manufacture board and hardwoods. The timber that comes from the coniferous tree is known as softwood and the timber that comes from deciduous trees is known as hardwood.?An example of softwood is pine, an example of hard wood is oak, and an example of manmade wood is plywood. - Pine-Spruce - Yew- Oak -Mahogany- Cherry- Beech-All plastics are based on?polymers?and bonding molecules together creates them. - There are two main types of plastics: thermoplastic and thermoset. -Thermoplastic: polyethylene, polystyrene - Thermoset: polyester resin, melamineTextile Metal Plastic Wood Material research
