THROUGH research and development (R&D efforts, bamboo is now the newest addition to the local natural textile fibers joining pineapple, abaca, and banana, which are being converted into textile or fabric through the Department of Science and Technology (DOST)’s textile processing technology.
Various nations, including the Philippines, have pushed for the increase in people’s awareness of bamboo’s importance in our lives, and House Resolution 197 added to the recognition to proclaim the month of September as the Philippine Bamboo Month.

The Philippine Textile Research Institute, the textile arm of DOST (DOST-PTRI), has been invested in developing natural textile fibers as better options to petroleum- and chemical-based synthetics. It has since included bamboo to its efforts at nurturing natural textile materials to support the Philippine contribution towards the attainment of the United Nations’ Sustainable Development Goals (SDGs), in particular, SDG12, on sustainable consumption and production.
To maximize local bamboo as a vast natural resource, the PTRI promotes its bamboo textile processing technology for the production of natural blended yarns and woven fabrics. Noting that bamboo has the highest textile fiber yield among other textile fibers like pineapple, banana, or abaca, more significant opportunities will be provided for income generation from upstream to downstream for the natural textile industry sector.
The PTRI technology has been optimized following mechano-chemical processes, and has noted significant increase in value of the bamboo pole (Php5 per kilogram), to its transformation into bamboo textile fibers (BTF) in spinnable form (Figure 1) to spun yarns (Php910 per kilogram) seen in Figure 2.
In one hectare of a bamboo plantation, there will be over 4,589 kilograms of spinnable bamboo textile fibers that can be obtained and when it is transformed into yarns, an estimate of 12,500 kilograms of yarns composed of 75/25 blended ratio of cotton and bamboo textile fiber can be produced.
It is also notable that the developed process is community-centric and sustainable in the conversion of poles to textile, the processing being one other than the regeneration route popularly known as the viscose process, an open system that is known to adversely affect the environment. Diversifying and expanding bamboo use through sustainable textile processing is a step to mainstreaming bamboo as a natural textile.

Bamboo Textile Fiber Innovation Hubs
Figure 4. Bamboo Textile Fiber Innovation Hubs map
DOST-PTRI identified eight provinces in the Philippines, which are proposed as potential Bamboo Textile Fiber Innovation Hubs (BTFIH) as seen in the photo above. These hubs will serve as the gateway towards sustainable bamboo textile production and manufacturing given the ample bamboo plantation in their area.
It seeks to boost the local economy through the utilization and value-addition of bamboo for the farmers, cooperatives, and/or local processors who may adapt the developed technology.
Let us aim to create BTFIH in the said regions of the country to make bamboo fabric available in our towns and push for funding of such textile innovations that will spur growth in the countryside.
