The core application of nylon BCF is in tufted carpet industry. It is preferred for use in crowded places such as home bedrooms, commercial offices, hotel lobbies, and cinemas. It is also widely processed into automotive interior floor mats, construction machinery anti-slip floor mats, and exhibition carpets. The daily maintenance of the products mainly involves regular vacuuming. Floating dust should be removed promptly. Stains should be wiped with cold water and neutral cleaning agents in a local area. Strong alkaline cleaners and hot water soaking should be strictly prohibited to avoid damaging the fiber's rebound performance due to exposure to sunlight and drying. During industrial production and storage, it is necessary to prevent moisture and light exposure. The yarn storage should be kept dry and ventilated to prevent moisture from forming lumps. The modified anti-stain types have low stain adhesion, making daily maintenance simpler, and the service life is more than twice that of ordinary chemical fiber carpets.
