Physical Description

Summary, Etc.
This aim of the study is to determine the differences in the crystalline structures of abaca (Musa textilis), banana (Musa acuminata colla), and pineapple (Ananas comosus) fibers, since these structures affect the various processes by which fibers are prepared for textile production. The three fibers were compared to each other and to cotton, a fiber with an established analysis of its crystalline structure. The goal of this comparison was to pattern the processibilty of these fibers to that of cotton. Five levels of observation were used: visual inspection, simple optical inspection using a compound light at 40x magnification, scanning electron microscope (SDEM) at 150 x to 7500x magnification, electron dispersing x-ray, and x-ray diffraction. It was seen that the raw samples exhibited a more frayed structure than the treated (degummed) ones; these displayed a smooth, straight stalk. Under 40 times magnification, the surface of the raw fiber samples seemed more tattered and striations can be seen. The samples were further observed with a scanning electron microscope (SEM). At closer ranger (350 x upwards), the fibers displayed greater distinction due to the characteristics of the individual fibrils in the stalk. This attribute was most evident in raw pineapple fibers. Elemental observation was performed using an electron dispersing xray. All of the samples exhibit high concentrations of carbon and oxygen. The differences in the composition of the samples were exhibited in the ratio of carbon and oxygen. The differences in the composition of the samples were exhibited in the ratio of carbon to oxygen and in the content of other elements, xray diffraction patterns which showed evidence of differences in the fibers' crystalline structure. It was observed that the crystallinity of degummed pineapple was closest to that of cotton. Experimental findings suggest that degummed pineapple has the highest potential to be developed as fabric akin to cotton. Since its crystallinity is closest to cotton, by it having the least order in crystalline structure among the three, it is more likely to behave like cotton, which is the most fibrous and possess the most orderly structure of all fibers. In this project, it was determined that the less orderly the crystalline structure of the fiber is, the better the fiber is, in terms of its similarity to the structure of cotton
