The innovation means that Lenzing can bring the softness of its modal fiber to fashion’s favorite color. Lenzing Modal Black is a spun-dyed fiber that utilizes the approach of incorporating the pigment during the extrusion production process, thus fixing the dye permanently into the fiber structure.
Lenzing Modal Black continues Lenzing’s sustainability commitment, as it requires minimum inputs, such as chemicals and energy, versus conventional dyeing. Compared to conventional dyeing, Lenzing Modal Black uses only 20 percent of the pigment typically required with spun-dye fiber.
Lenzing said research has shown that fabrics made with Lenzing Modal Black fiber uses 50 percent less energy, has a reduced carbon footprint of 60 percent and requires only 50 percent of the water typically used in production compared to conventionally dyed fabrics.
Lenzing Modal Black can be used on its own or blended with other fibers to create a variety of effects. Consumers of modern denim will appreciate the denim’s softness, comfort and exceptional color fastness, Lenzing noted. Modal has widespread usage in the intimate apparel and sportswear markets.
“Due to the large and growing consumer demand for black jeans which retain their color, we’ve worked with the global supply chain to develop fabrics using Lenzing Modal Black,” said Michael Kininmonth, project manager from Lenzing. “We are delighted with the performance of jeans made with Lenzing Modal Black as, even after 50 plus washes, they show no sign of color loss.”
Lenzing supplies the global textile and nonwovens industry with high-quality, botanic cellulose fibers. Its portfolio ranges from dissolving pulp to standard and specialty cellulose fibers. This includes the classic viscose to modal and the lyocell fiber Tencel.
Lenzing operates its factories on a closed-loop manufacturing system to limit waste and energy. In 2015, Lenzing had revenue of 1.98 billion euros, or $2.17 billion, with a fiber sales volume of 965,000 tons.
