As a pioneer of the denim manufacturing industry in Pakistan, Siddiqsons firmly believes in giving back to nature through investing in enhanced recycling techniques and reducing the use of water, energy and chemicals in the production process.
In line with its goals to build a more eco-friendly textile and apparel industry, Siddiqsons has adopted the motto, “Small contributions make a huge difference.’’
Introducing Indigo H2Zero: the company’s most sustainable denim fabric process.
In partnership with Archroma, Siddiqsons launched Indigo H2Zero, a new method of aniline-free indigo dyeing designed to make the process more sustainable by addressing production-friendly limitations such as higher biochemical oxygen demand/chemical oxygen demand (BOD/COD) values, excessive water usage, non-organic fixing agents, high energy consumption, salt formation, high-intensity labor, the reusability of dyes and shading issues in bulk.
The launch comes a year after Siddiqsons adopted Archroma’s aniline-free indigo across its entire production after a series of wash-down dye tests proved that the company could make a full transition to the new process. Traditionally, during indigo production, some aniline stays locked into the indigo pigment and can be very difficult to remove from the fabric, with the remaining residue discharged into the resulting effluent. The toxicity that aniline brings can pose a severe issue for surrounding marine and human life.
Indigo H2Zero provides unique laser- and ozone-friendly colors to mitigate the consumption of water throughout the process. There is no change of color in the product if the construction is chosen from a sustainable palette using materials such as Tencel, Refibra, recycled cotton, organic cotton or hemp.
The process includes the application of Archroma’s pre-reduced aniline-free indigo, which can save up to 80 percent water and uses only GOTS-certified organic fixing agents. Additionally, it requires no salt and needs up to 70 percent fewer chemicals than conventional indigo dyeing processes. This process does not consume any heat, therefore producing no salt in the dye, which in turn helps recover 100 percent of the indigo.
Indigo H2Zero marks the core process of denim dyeing (i.e. indigo dyeing), which has always been neglected in the rush to adopt environmentally friendly practices.
Approach to sustainability
By using advanced technology and supporting renewable energy sources, Siddiqsons believes in meeting customer expectations by keeping innovation and sustainability parallel.
Their in-house innovative engineering and constant collaboration with international partners like Archroma to create better solutions allows them to produce eco-friendly fabrics and sustainable garments using organic cotton and recycled fibers while reducing water dyeing.
For example, Siddiqsons adopted the Laundry 5.Zero production center from textile finishing technologies company Jeanologia, making it the only denim mill in Pakistan to use this technology so far.
With the denim manufacturer operating with the mindset that a process is never sustainable unless it is supported by verification tools to gauge its authenticity, Siddiqsons emphasizes the importance of 5.Zero’s built-in traceability software, which allows it to trace the activities of each step involved in the 5.Zero process. With this Environmental Impact Measuring (EIM) tool, Siddiqsons can trace water and air consumption for ozonic processes and chemicals usage in the denim production process.
Every garment and fabric that leaves Siddiqsons has a QR code sharing the complete DNA of the product’s cotton field, indigo usage, and amount of water and energy consumed, alongside the EIM score detailing the garment’s impact on the environment.
Transparency in today’s apparel manufacturing environment is a must, but Siddiqsons feels it has a duty to represent the industry as a whole. To take a lead in this initiative, the denim manufacturer is committing to 100 percent transparency within its supply chain.
