Soko Chimica touts powers of Black Magic
06/01/2021
Italian chemicals company Soko Chimica has developed a product for black denim that saves water by achieving the same bleaching in single bath of water that would normally be achieved in two or more, and which also saves time and energy, it claims.
Matteo Urbini, managing director of Soko Chimica, said: “Grey denim will be a strong new trend for the coming seasons but even so, the discolouration or bleaching of sulphur black denim is a regular part of the industrial process. This operation requires plenty of water as it needs several steps and baths, high temperatures and high emission of CO2, plus, alkali washes are quite aggressive on fabrics. Our new product makes the process much more environmentally and production friendly.”
Black Magic works at 50°C rather than the conventional 80°C, reducing steam, and works at pH10, meaning gentler processes can be used, eliminating the need for caustic soda.
The process means less stress for fabrics, in particular stretch fabrics, which can result in fewer rejects, according to the company.
“Black denims will always be part of any brand’s collections,” he added. “Black Magic is the Soko sustainable solution for faster discolouration.”
