Introduction of Allo
Allo (Himalayan nettle, stinging nettle) is a perennial shrub belonging to the Urticaceae family (Girardinia diversifolia). The stem bark of allo contains fibres with unique strength, smoothness, and silk-like lustre. Allo found at altitudes between 1,000 and 3,000 meters above sea level, contains chemicals like histamine, serotonin, and acetylcholine, which cause a burning and itching sensation. In its natural state, it can grow up to 3 meters tall, with a thick stem reaching up to 4 cm in diameter, while its root can extend up to 90 cm in length. It plays a role in watershed development by helping to prevent landslides and contributing to water retention. The plant's leaves measure between 10 to 24 cm in length and 7 to 18 cm in width.
Allo, a natural fiber abundant in Nepal's Himalayan and mountainous regions, offers numerous environmental and economic benefits. It serves as a sustainable resource with minimal environmental impact, playing a key role in soil conservation and preventing erosion through its deep roots. Allo cultivation aids watershed management by maintaining soil moisture, and supports biodiversity by preserving natural habitats. The production process uses fewer chemicals, reducing pollution and promoting environmental health. Economically, Allo provides sustainable income for local farmers and artisans, while also preserving cultural heritage. Its eco-friendly methods help reduce carbon emissions and combat climate change.
Processing Stages
Bark Removing
The process of preparing Allo fiber begins with extracting the bark from its stem and allowing it to dry.
Cooking
The bark is boiled using wood ash or caustic soda.
Beating
After boiling, the bark is repeatedly beaten using small logs or a beating machine. It is then cleaned, and the fiber is checked for visibility. If the fiber is not yet visible, the bark is beaten again until the fiber appears clearly. The visible fiber is cleaned once more and dried in the sun.
Thread making
The fiber is spun into thread using a manual charkha machine. The thread is then ready for cloth-making and is sent to textile factories, where it is turned into valuable products.
