Made up of thick-walled cell tissue and bonded by natural gums, banana fibre is similar to natural bamboo fibre but its fineness and spin ability are better bamboo and ramie fibres. Strength, extension, fineness, length and surface properties are some of the primary attributes of fibres which, using different types or blends of fibres, create a wide spectrum of useful and desirable physical and mechanical properties in the yarn and fabric produced. Spinning converts fibres into yarn. There are several thicknesses of craft yarn, also referred to as weight.
