Novel Biobased Textile Fiber from Colombian Agro-Industrial Waste Fiber

Molecules, 2018
Fique fibers, native to Colombia, are traditionally used for ropes and bags. In the extraction of long fibers for these purposes, the same amount of short fibers is generated; the short fibers are then discarded in the soil or in landfills.

Influence of Incorporation of Natural Fibers on the Physical, Mechanical, and Thermal Properties of Composites LDPE‐Al Reinforced with Fique Fibers

International Journal of Polymer Science, Volume 2015, Issue 1, 2015., 2015
This study shows the effect of the incorporation of natural fique fibers in a matrix formed by low‐density polyethylene and aluminum (LDPE‐Al) obtained in the recycling process of long‐life Tetra Pak packaging. The reinforcement content was 10, 20, and 30% fibers, manufactured by hot‐press compression molding of composite boards (LDPE‐Al/fique).

D(‐‐)‐Lactic Acid Producing Probiotics, D(‐‐)‐Lactic Acidosis and Infants

Canadian Journal of Gastroenterology and Hepatology, Volume 18, Issue 11, Page 671-675, 2004., 2004
There is mounting evidence that ingestion of selected probiotics can modify disease morbidity for specific conditions affecting humans, and there is growing interest in the amelioration or prevention of disease with probiotics. Modulation in gene expression of the cellular elements of the intestinal mucosa and interbacterial interactions are leading ...
