Fabrics can be found in everyday apparels, bags, purses, and covers; it performs a
significant role in the local economy as commercial products, gifts, and cultural objects.
This study is focused in the development of an antibacterial bag fabric using bamboo yarns
and infusion of a chemical with high antimicrobial properties. The product was made of
70% bamboo yarns, 30 % polyester and cotton threads, and copper oxide, where the
bamboo yarns, cotton thread, and polyester thread were weaved into the weaving loom
(habihan). After the fabric was made, it underwent the staining procedure in which the
fabric was soaked for 5 hours in the mixture of 1:1 ratio of water and copper oxide in order
for the fabric to absorb the chemical more effectively. Copper oxide has high antimicrobial
properties. The fabric itself had no antibacterial impact on the microorganisms in the
sample bacteria’s used, such as the Staphylococcus Aureus (S. Aureus) and Escherichia
Coli (E. Coli). The fabric was dried and microbiologically tested, the test result implies
that after staining, the fabric with copper oxide develops antimicrobial characteristics and
had an 8mm to 9mm zone of inhibition into the test plate. The result shows that the
bacterium becomes reactive into the sample fabric stained with copper oxide. Another test
conducted is the tensile test, which determines the fabric's strength and weight capability.
It undergoes a gravitational force, and determined that the fabric can withstand up to 105N
per 102
/mm, or at least 10.7 kilos of force per 102

/mm. T=F/A is the formula used to
calculate the 10.7 kilos of ultimate stress that the fabric can withstand until its collapsing
point. Where T stands for Ultimate Tensile Stress, F represents for Force (105N), and A
stands for Cross Sectional Area (102/mm). Using a Likert Scale, the product was presented
to, and evaluated by 29 respondents, and got an overall mean score of 4.001 with the
descriptive rating of “Very Acceptable”. These only shows that the formulated fabric can
be used for bag material, wherein it can eliminate the transmission of bacteria. It can also
make a significant contribution on the promotion of local weaving industry.
