It has good insulative properties and medium - high durability. It is typically graded using surface pile mass (g/m²), with a higher g/m² generally indicating a higher quality and more durable product.<br><br>Tufted carpet is available in three standard styles: 'cut pile', 'loop pile' and 'cut & loop pile'. Within these styles, there are significant variations in durability, aesthetic qualities and cost. During production, carpet fibre is sewn directly onto a primary backing fabric and then bonded (commonly using latex) onto a secondary backing layer (hessian, or similar). Common carpet fibres include: Nylon, Polypropylene, Wool, Wool-blends, Polyester and Acrylic.<br><br>Nylon carpet is generally cheaper than wool alternatives. It is stain resistant and holds its colour well. High durability and toughness make it ideal for use in high-traffic areas.
