Merino wool’s overall natural stain and soil resistance is significantly better than that of cotton or synthetic fibres. It has a natural protective layer that is bonded to the surface and can therefore not easily be removed. These overlapping scales are slow to absorb liquids and thus allow spills to be wiped off before permanent staining occurs. Merino wool only generates very little static electricity and does not attract dirt or lint as most commonly used textile fibres. Further information can be found in our stain removal guide for interior fabrics.
Polluted indoor air can lead to discomfort, reduced efficiency or even chronic insomnia. Air pollution can be caused by the use of air conditioning systems, evaporation from certain building materials and furniture or combustion processes.
Merino wool can absorb molecules from pollutants such as formaldehyde, nitrogen oxides and sulphur dioxide. Furthermore, wool does not re-emit these noxious gases. It is estimated that wool purifies indoor air for up to 30 years.
Merino wool is naturally flame resistant due to its high water content and chemical structure. It is less likely to burn (with a very high ignition temperature of 600°C) and produces less noxious fumes and toxic gases than most synthetic textiles or cotton, which makes it a much safer choice for interiors. When wool burns it neither drips nor melts so it cannot stick to the skin like most artificially manufactured fibres, sparing burn victims from severe injuries.
With a Limiting Oxygen Index (LOI) of 25, wool has the highest LOI among the commonly used textiles. This indicator is used for ranking the flammability of materials by measuring the amount of oxygen needed to sustain combustion. The higher the value, the less flammable the material.
