<p>Multicolor flooring articles such as carpets are made from combined yarns (10) of at least three component yarns. At least one of the component yarns (1, 2, 3) is an acid dyeable nylon yarn; at least one of the component yarns is a cationically dyeable nylon yarn; and at least one of the component yarns is a poly(trimethylene terephthalate) yarn. The component yarns (1, 2, 3) are combined either by commingling with air or by cable twisting. The combined yarns (10) are tufted or woven into a carpet. When dyed using acid, cationic and carrier-free disperse dyestuffs of different colors, the resulting carpet exhibits at least three different colors.</p> |
