US' Avient expands portfolio with new black colourants

Avient Corporation, a leading provider of specialised and sustainable material solutions and services, has announced it is adding new black colourants to its Renol Fibre Colourants portfolio. These colourants can achieve intense, high-quality levels of deep jet-black shades (jetness) in polyester textiles increasingly desired by manufacturers of automotive, apparel, and home décor applications seeking a more luxurious appearance. 

The textile market has long sought deep black colourants that offer exceptional jetness to textiles without incurring high costs. Deep black is perceived by customers as more attractive, conveying an impression of high quality in contrast to less intense black shades, which can look washed out. In addition to a high level of jetness, deep black colourants require very high light fastness (resistance to fading and discoloration when exposed to light) for automotive applications, robust wash fastness (resistance to frequent washing) for sportswear, and resistance to fading from frequent use for fashion and home textiles. 

“Satisfying all of these needs for deep black colourants in the textile industry have proven to be challenging over the past few years as certain colour technologies could meet only one or two but not all requirements,” said Mauro Dallavalle, senior marketing manager, colour & additives fibres at Avient. “Our new deep black colourants are formulated to help meet all of these needs and can be customised to achieve a specified deep black intensity in virgin and recycled polyester grades, making them suitable for different textile applications.” 

The new deep black colourants are part of the Renol Fibre Colourants portfolio, a range of colour concentrates specially formulated for dyeing synthetic yarns using the spin-dyeing (dope-dying) process. In this dyeing process, colour is added during the yarn manufacturing, which reduces the number of steps and energy used to dye yarn. This process also uses no water, making it a more eco-conscious alternative to traditional wet dyeing methods.
