from tufting can be turned into many things, including cushion stuffing, as concrete reinforcement or as modifiers in asphalt mixtures. Tufted pieces, such as rugs or wall hangings, provide acoustic properties which can minimize noise and absorb airborne sounds. They also provide thermal comfort when walking on tufted rugs with bare feet, and larger pieces provide insulation which may reduce the cost of heating. Rugs or wall hangings made from wool fibres have been shown to improve air quality in indoor spaces. Wool acts as a filter through which contaminants such as sulphur dioxide and nitrogen are absorbed. Wool is also a highly absorbent fibre and can help manage humidity changes indoors. Tufted carpets and rugs provide a safe surface to walk on, offering slip resistance and a more forgiving surface should objects be dropped or falls occur. Wool carpets are also resistant to flammability and hide soil and other dirts well. Tufted pieces made from nylon yarn may face colour degradation over time if exposed to excess sunlight.
