TAGUIG CITY – Five scientific papers of DOST-PTRI researchers submitted as posters were presented in the Rapid Fire Competition which was held today, August 12, 2020, as part of this year’s celebration of the 40th Philippine – American Academy of Science and Engineering (PAASE) Anniversary & 2020 APAMS (Annual Scientific Meeting) Philippines.
The poster sessions, grouped into 4 categories, were conducted from August 6 – 11, 2020. Seven scientific papers of the DOST-PTRI fall under Group C category of Material Science, which was presented/posted on PAASE’s website last August 10, 2020, from 9:00 AM – 5:00 PM. The list of the DOST-PTRI poster submissions are seen below:
Scientific Posters of DOST-PTRI Researchers for the PAASE and APAMS Poster Session:

Brief Description of the Research |
|
1 |
High Molecular
Weight Carrier-stabilized Spray Drying of Aqueous Talisay (Terminalia catappa) Leaf Extracts as
Natural Dye for Textile |
Joanna Tess M.
Manuel, Dr. Julius L. Leaño, Jr. |
This study explored
an additive that was found to be suitable for spray drying Talisay extract to
increase its powder yield production and its storage stability as a natural
dye. |
|
2 |
Varietal and
Locational Variability of Philippine Pineapple (Ananas comosus) Leaf Fiber Fineness for Spun Yarn Processing |
Agustin A.
Bordallo, Jr., Eduardo M. Marin, Dr. Julius L. Leaño, Jr. |
A project wherein
decorticated pineapple leaf fibers (PALF) from 3 varieties of pineapple plant
namely Formosa, Hawaiian, and F200 from different localities were evaluated
based on their physico-chemical properties and processing performances in
producing 75/25 ratio blend of cotton/PALF blended yarn. |

Commercialization
of Bivoltin Bombyx Mori L Silkworm
Hybrid Cocoon Production in Support of Philippine Silk Industry |
Cheryl G. Lopez,
Serenita S. Ompoy, Vincent Michael E. Salon, Ronnie M. Liguan |
The study focused
on the rearing performance, cocoon characteristics and grading, and the raw
silk properties of the four (4) different DOST-PTRI hybrid lines of silkworms
reared in different production areas. This highlights the contribution of the
institute in improving silkworm hybrids and to the achievements of the
Philippine silk industry. |

Digitization of
Traditional Filipino Weaves Using a Computer-Aided Design Software
(Weavepoint©) |
Cornelio V. Loyola,
Jr., and Dr. Julius L. Leaño, Jr. |
The research
centered on the aim to digitize and generate manual draft of the Binakol
pattern of Ilocos, Hablon pattern of Iloilo, and the Inaul pattern of
Maguindanao using a CAD program, by means of Weavepoint© in order to advance
the product development and innovation of the traditional Filipino textile
weave patterns. |

5 |
Thermoacoustic
Nonwoven Textiles from Abaca (Musa
textilis Nee) Fibers |
Roberto O. Casero,
Dr. Julius L. Leaño, Jr. |
The potential
application of Musa textilis Nee
abaca fiber for nonwoven fabric production was investigated. The treatment of
abaca fiber with dilute alkali solution and bleaching agent resulted in finer
fibers with decreased residual gum content. This is indicative of the optimal
reduction of non-cellulosic components which is important in nonwoven fabric
production. |
|
Mechano-Chemical
Natural Textile Fiber Extraction of Kawayang Tinik (Bambusa blumeana) Bamboo |
Eduardo M. Marin
and Dr. Julius L. Leaño, Jr. |
The study explored
the most efficient method for mechanical, chemical, and bio-retting
treatments for Kawayang Tinik bamboo fiber extraction as a textile material
source. |
|
|
7 |
Pineapple
Leaf Fiber-blended Yarns with ≥ 40% (w/w) Content using the
Semi-Worsted Spinning System |
Ronald S.Pechera ,
Dr. Julius L. Leaño, Jr. |
Two appropriate
spinning systems were used in the study utilizing both short and long staple
spinning systems. The semi-worsted spinning system for the pineapple (Ananas comosus) leaf fiber (PALF)
enables the development of more PALF from 25% to 60% w/w. The established
higher composition (>40%w/w) promises more opportunities for farmers in
extending the value of PALF which is considered as an agricultural by-product |
The first five researches in the above list were chosen to be presented in the Rapid Fire Competition. Each of the researchers was only given 3-5 minutes to present and pitch their respective researches in the field. The winner of the competition will be announced on August 14, 2020.
The Institute is equally proud of Dr. Julius L, Leaño, Chief of the Research and Development Division of the institute, on his induction as a new Associate Member of the PAASE organization on the same date as the Rapid Fire Competition.
The PAASE is a non-profit organization with more than 300 distinguished members from the Philippines and the United States of America and includes those from around the globe who are engaged in various scholarly and research-related activities. Their month-long anniversary is celebrated through Online Congress from July 20 to August 14, 2020, with the conduct of hundreds of webinars and conferences of plenary and parallel sessions to advance engineering, science, and technology while collaborating with fellow scientists and engineers, including the topic of the times: various COVID-19 initiatives.
