This spring, we announced the theme " New age unleashes Hemp ," announcing that plant fiber ( textile hemp ) has emerged as a material suited to the new age.
Weavearth promises to be as open as possible about its brand resources. We would like to introduce the actual technical points along with the actual process (first time in Japan).
Details of the visit are in the first and second parts . For the technical part, see Retting and Decortication.
During decortication (the process of separating the outer bast fibers from hemp), the inner woody core, commonly called "ogara" in Japanese and "hurd" in English, is separated and stored in a separate building without being spun (processed into yarn).

The use of this part is very interesting.
In practice, this part is compressed and processed into fuel pellets. It has also been reported that it can technically be processed into plant-derived coal called "bio-coke," attracting attention as an "energy source material that can be cultivated agriculturally."

In addition, the hurd that has been separated for these fibers can be processed into cellulose fiber, which is a woody component, and can potentially be made into rayon yarn. Major viscose spinning companies have already started to develop this raw material.
The area where hurd is currently being most widely used and expected worldwide is in the processing of building materials as a replacement for petroleum-derived raw materials. Hemp contributes to CO2 reduction from the time of cultivation, and its use in building materials is also highly promising. In fact, it is being widely used in the infrastructure for the Paris 2024 Olympics, which has the theme of coexistence with the environment. Some of the hurd produced in this region will also be exported to Europe.
Industrial hemp has the potential to revolutionize agriculture in many new industrial fields. Its development is underway all over the world.
