Solution Dyed Nylon (SDN) is a high-performance carpet fibre designed for strength, durability and excellent colourfastness, with colour locked throughout the fibre to help maintain its appearance in high-traffic areas and busy homes. Polyester carpet is a synthetic fibre known for its soft feel, offering a wide range of design options suited to comfortable, style-focused interiors. While both are popular residential choices, SDN is often selected for its enhanced resilience and long-term performance in active spaces, while polyester is valued for its softness and comfort-led appeal in everyday living areas.
