Conceptually, reducing the risk of disasters is closely associated with adaptation processes. A fairly conventional approach to disaster risk reduction (DRR) characterizes preparation as part of a continuous cycle of activities that move from disaster events through recovery (damage limitation) and risk reduction (preparation) phases until the next event occurs (Moench, 2007). Moench argues that climate change is increasingly recognized as among the greatest challenges human society will face over the coming century. While it will affect everything from basic ecosystem processes to the spread of disease, some of the greatest impacts are anticipated to occur due to increase in the frequency and intensity of extreme climate events, such as storm, floods, and droughts. Therefore, many of the elements identified in the cycle – strengthening of resilience, land-use planning, insurance, and the development of early warning information – should reduce vulnerability to the next event and thus, assist regions in “adapting” to the types of events that can cause disaster. However, the frequent occurrence as well as the increase in the intensity of the hydrometeorological hazards does not imply on enhanced perception and awareness of the people for preparedness, as experience is not the prime factor to it (Shaw, Shiwaku, & Kobayashi, 2004). In this sense, climate change related disaster management and risk reduction plans should be prepared targeting the concerned target population. A combination of clear and accurate warning messages with high level of preparation with an effort of self-reliance during the crisis time needs to be looked into (SEEDS, 2008).

This study aims to evaluate two bacterial cellulose (BC) films as an alternative textile surface suitable for use in the manufacture of clothing prototypes.

A combination of experiments for the production and characterization of BC films with traditional techniques for sewing fabrics was carried out. BC films were produced from the bacterum Gluconacetobacter hansenii UCP1619 and from Kombucha, a consortium of microorganisms grown on sugared tea. The BC films were then purified, characterized by scanning electron microscopy (SEM) and evaluated for mechanical strength. Two clothing prototypes were developed by combining BC films with a flat fabric composed of 70% linen and 30% polyester to assess the viability of the garment for future clothing making using biomaterials.

The results showed that the combination of flat fabric with BC-based biomaterials is a viable alternative for the innovative use of BC films in the manufacture of apparel products, especially after optimizing the mechanical properties of the artefact.

BC application studies in the textile industry are still in their early stages, although they are attracting more and more the attention of researchers around the world. The experiments carried out in this research provide new information on the handling and application of this material in innovative products for the textile industry.
