The process involves PET bottles being collected, washed and then crushed down into flakes
These flakes are then melted and turned into chips, which are then extruded into fibres
The fibres are then crimped, cut, stretched and turned into textile to create a garment
On average 35-40 bottles would be used to make 1 jacket
Lyocell is indeed a plant-based fiber, but it's also processed with advanced synthetic substances.
That means, it's neither all natural nor all synthetic: it's in the middle. And technically speaking, that makes it a semi-synthetic fiber
The making of Lyocell starts with harvesting wood, which often comes from eucalyptus trees.(it's also common to find Lyocell made of oak, bamboo and birch trees too)
This wood is broken down into tiny pieces and then chemicals are added to dissolve it into a wood pulp.
The result is a liquid and sticky raw cellulose.
By the way, these solvents do not change the chemical structure of cellulose, they're only an instrument to alter its form.
HeiQ Fresh is a family of silver-free odour control textile technologies with ingredients that are either bio-based or mineral-based
HeiQ Fresh products tackle the real problem of smells on textiles effectively by adsorbing VOC (Volatile Organic Compound or the “smelly molecules”).
Durable freshness and odor control
Various products in the range target different end-use, addressing body odours, environmental odours and fabric odours, as well as the accumulated effects on synthetic fibers (“permastink”)
Bio-based FFL regenerate with every wash
No impact on fabric properties such as breathability, colour, hand feel or wicking
