Among brands participating in the last edition of Denim Premiere Vision, Luigi Caccia, founder, Pure Denim, Italian manufacturer of denim, presented his company's newest denim developments while expressed his opinion about how truly sustainable denim can be.
"Stretch denim cannot biodegrade. I rather believe that making durable and long-lasting jeans that one can pass to younger generations is more sustainable," said Caccia.
"No stretch fiber can biodegrade as to produce any elastic fiber, they need to use the vulcanisation process which changes the molecular structure of the fiber. Therefore, a fiber cannot be recycled anymore after such a process," he added.
"Moreover, no laws exist yet to define the percentages of how much synthetic fibers can be thrown away to consider a textile as recyclable. In fact, our industry is sticking to laws related to packaging. This way, if a denim's not-degraded quantity in soil is 10%, that amount is still high. A regular stretch denim that releases 2% stretch fiber in the soil, instead, is less harmful," he continues.
"We developed this selection of denims made with Good Earth Cotton, a cotton that is grown in Australia according to a modern regenerative and socially sustainable farming program," explained Caccia.
This cotton can be traced through the Fibertrace technology that maps the global textile supply chain of the fabric from fiber to retail.
Moreover, for this collection they used Xlance, a high-tech stretch ingredient that helps fabrics remain stretch for long. Xlance stretch is one of the latest developments by Carvico Group, an Italian manufacturer specialised in producing jerseys for swimwear, therefore devised to last long and resist chlorine and other ageing agents. This special stretch fiber is also produced at low temperatures and without solvents, therefore its manufacturing produces fewer emissions.
These denims are also dyed by using Pure Denim's own Smart Indigo technology that is aged by using ultrasounds.
