Attending the International Conference on All-natural Fibers (ICNF) in Portugal not too long ago, it is fair to say I was blown away by some of the revolutionary suggestions and existing item developments in the all-natural fibers sector – and hemp is playing a larger and larger part.

Of
the extra than 150 oral presentations produced at the conference, a complete
10% have been about hemp. Hemp as biomass, textile applications, sorbents,
fibers, you name it. A number of other presentations about cellulose have been
also largely primarily based on hemp, as have been a couple of that explored lignin, which
also can be derived from hemp.

Enormous shift

This
is a enormous shift from preceding conferences exactly where jute and flax
would have been most prominent on the system.

All the things from harvesting, de-gumming, finish use applications, scientific and technical advances in all-natural fibers was discussed. But I was especially struck by a important breaktrough presented by Thomas Scheibel, University of Bayreuth, Germany, and co-founder of the biotech organization AMSilk, who is operating with biomimetic spider silk.

Scientists say that if massively scaled up, a spider-constructed net would be robust sufficient to catch a jetliner. They have found that the webs get their strength by way of thousands of smaller sized strands that stick with each other to kind the spider’s trap. Such “dragline silk” exhibits extraordinary mechanical properties combining a moderate strength with very good stretchability that final results in a toughness exceeding all other all-natural or synthetic fibers, Scheibel told the conference. Certainly, spider silk or “spider steel” has lengthy been mooted as a material of practically mythical qualities, but no a single could make it outdoors of nature till now.

Mimicking the spider

Scheibel
told how the material is becoming made by way of bio-mimicry in which
the actions of a spider’s back legs are replicated mechanically.

This is not just theory. At present, Omega is creating watch straps from this material, and ADIDAS is testing it for a new line of trainers and footwear.

The
net is pure protein, anti-microbal, anti-bacterial and appropriate for
several applications each industrial and health-related. In theory if you have been
stuck on the side of a mountain you could consume your footwear to sustain
oneself. It does not sound pretty appetizing, but it is only protein!

Can hemp match in?

Hemp,
becoming each a protein and cellulose primarily based plant, appears to have the
qualities important to adhere to the spider silk. When I
collared Scheibel with this suggestion following his presentation, he
was pretty upbeat about hemp’s possible in this application.

As
spider silk is a single of the toughest components identified to man, obtaining a
dependable approach and optimal components to make it may perhaps prove to
be invaluable.

One more
presentation at the conference, a timeline of fabrics each all-natural
and man-produced, also proved rather insightful. Hemp, jute, wool and
silk fabrics becoming archaeologically established to have been employed by man
for centuries, therefore followed in 1823 Waterproof Fabric (the Macintosh
raincoat) Rayon (1855) Denim (1873) Viscose (1894) (derived from
Rayon) Vinyl (1926) Nylon (1938) Polyester (1941) Velcro (1955)
Spandex (1958) GORE-TEX (1958) and Kevlar (1965).

Dreaming of spider webs

Any
material made considering the fact that 1965 has been either a blend or an adaption
of a single of these components and, as most reading this will know, the
ban on hemp that began in 1945 hampered any important influence with this
material in the intervening years.

I’ve
been dreaming of spider webs ever considering the fact that Portugal. And questioning if
Scheibel’s perform may in the end make however an additional fascinating
application for this remarkable plant as hemp enters a new paradigm.
