Scientists in the Philippines have devised greener technology for producing bamboo fibres that retain bamboo’s innate antibacterial and UV-blocking qualities. The commercially available method of turning bamboo into textile material is cellulose renewal, which does not maintain the characteristics of bamboo textile fibres.
The Department of Science and Technology (DOST) developed the technologies to generate greener bamboo textile materials through its Philippine Textile Research Institute (DOST-PTRI). Bamboo textiles are gaining popularity as a sustainable and environmentally friendly choice for textile manufacturing methods. DOST-PTRI Bamboo fibre extraction method was initially created in 2015, and an application to protect intellectual property has been filed with the Intellectual Property Office of the Philippines (IPOPhil). Mechanical, chemical, and biological techniques are used to extract fibres from the bamboo culm. The extracted bamboo textile fibre is processed in order to produce highly cellulose textile fibres.

The method generates tough and fine bamboo fibres when applied to many bamboo species in the Region, including Kawayan Tinik (Bambusa blumeana), Bolo (Gigantochloa levis), Yellow Bamboo (Bambusa vulgaris), and Giant Bamboo (Dendrocalamus asper). Gentle and eco-friendly technique, combined with the ease of collection and treatment, making it ideal for textile fibre production in distant bamboo-rich locations, delivering economic benefits to the bamboo textile sector. Bamboo culms are broken down into chips, dissolved, and extrusion through spinnerets to form thin staples or filaments in the more prevalent commercial process of converting bamboo into textile material Called cellulose regeneration. This artificial approach introduces novel fibre qualities while preserving the natural purity of bamboo textile fibres. The process is also linked to the creation of poisonous and harmful compounds. Bamboo fibres are utilised in the manufacture of spun yarns that meet only 25% of the standards for government outfits. The domestic market accounts for 635,000 kg of processed bamboo fibre input material for spinning yarns.
