WHY LYOCELL THREAD

This brand started being aware about the problem of plastic pollution in the oceans. Implementing industry standard polyester or Rpet thread was not an option as we keep the same problem about the biodegradability of the garment. Organic cotton is still  neither  an option has not enough thickness for outside seams, we hope we can  use in the future. Lyocell is fully biodegradable and provided the strength we need it. Our tree fiber is sourced from South African silviculture plantations that minimize fertilizer and rely on rainfall, not irrigation.

Lyocell TENCEL™  fiber is a man-made cellulosic fiber. It is made by chipping wood and processed into pulp before being processed into fibers. The process developed by Lenzing involves direct dissolution of cellulose pulp in an organic solvent, without any chemical change and recovers more than 99% of the solvent in a closed loop. On the other hand, viscose, rayon and bamboo use toxic solvents called sodium hydroxide and carbon disulphide in an open system.

ENVIROMENTAL BENEFITS

Results indicate that Lenzing lyocell fiber has the following potential impact savings over conventional cotton [1]:

  • It requires no irrigation, It reduces to 95% blue water footprint compared to cotton(283 l/kg).
  • It needs no treatment with pesticides, and no fertilizer.
  • Reducing agricultural inputs Co2 as no pesticide, it is 76% reduced global warming potential.
  • Reduce impact on wildlife: 77 % percent reduced eutrophication potential.
  • Without fertilizer or irrigation needed our organic cotton uses: 70 % less primary energy

ORIGIN MATTERS

The wood pulp purchased more than half comes from South Africa from FSC plantations  (eucalyptus and acacia). South Africa is a water-limited country with an average annual rainfall of 560 mm year.The rest comes from wood (birch,beech,aspen..) grown in FSC semi-natural forests of  the USA, PEFC central Europe and Scandinavia. Often we read that the wood pulp purchased by Lenzing  raw material comes from Austrian forests but this is not applied by Lyocell fabric . Origin of this wood matters because according to environmental not for profit Canopy 1/3 pulp  used in the industry comes from ancient and endangered forests.

Altought is a fiber considered as low water comsuption, it has other water impacts. South Africa is a water-limited country with an average annual rainfall of 560 mm year. Plantations of exotic species were established in the higher-rainfall >700mm per year. Annual evapotranspiration rates of  indigenous vegetation range from 700 to 900 mm. Evapotranspiration from established forest plantations is commonly in the range of 1100–1200 mm and is limited by rainfall available on the site . Numerous local and international studies have indicated conclusively that forest plantations established in former natural forests, grasslands, or shrubland areas consume more water than the baseline vegetation, reducing water yield (streamflow) as a result.

WORK IN PROGRESS

We want to add this quality in our main fabrics as is much less thirsty than cotton.  Being aware that it should  come from managed sustainably forest. Fashion industry could not move all production to silviculture plantations because it will mean more deforestation.
