Structural Parameters of Polyester Fibers from an Egyptian Manufacturer

Abstract

Three different techniques have been used in this work to examine the morphological and structural properties of polyester fibers from an Egyptian manufacturer. The scanning electron microscope was used to examine the surface topography and the shape and area of the transverse sectional view of these fibers. This information was used with that taken from double-beam microinterferograms to calculate the refractive indices and birefringence of the fibers. The x-ray diffraction technique was used to investigate some structural parameters of polyester fibers.The study of optical properties of fibers is important in elucidating their structure. The birefringence and refractive indices of fibers for plane polarized light vibrating parallel and perpendicular to the fiber axis are useful source of information about their structure. Because no single technique can give a complete picture of the molecular arrangement of fibers, the optical studies are made in conjunction with x-ray diffraction and electron microscopy investigations [3]. X-ray diffraction is a powerful physical technique for investigating the atomic and molecular structure of fibers.The scanning electron microscope (SEM) is a useful tool for studying the surface properties of fibers, which play an important role in textile technology.

Determining the optical and geometrical properties of irregular fibers during the dynamic cold drawing process

“…Interferometric techniques were developed for studying the optical and geometrical properties of fibers. [1][2][3][4][5][6] Many authors [7][8][9][10][11][12] used the principle of optical diffraction, laser scattering, optical and scanning electron microscopy to determine the geometrical dimensions of fibrous material. Hamza et al 13 modified a manipulation device 14 to rotate the fiber around its longitudinal axis.…”

Interferometric determination of regular and/or irregular transverse sectional shape of homogeneous fibres

“…Clark and Whiteley [1], Curry and Schawlow [3], Hamza et al [2,4] and Sokkar and El-Bakary [5] made use of the principle of optical diffraction or laser light scattering properties of a single filament to determine the geometrical dimensions of fibrous material. Others [6,7] have used optical and scanning electron microscopy for determining these dimensions.…”

Determination of Refractive Index and Material Dispersion of Step Index Optical Fibers Using Variable Wavelength Interferometric Technique

“…Zurek and Zakrzewski (1983) [5] determined the refractive indices and birefringence of cotton fibers using the Pluta microscope. Hamza et al [6][7][8][9] Used Pluta polarizing interference microscope for different fibers with regular and irregular transverse sections to determine its refractive indices and birefringence. Hamza et al [10] (1994) used this microscope to study the refractive index profiles of cylindrical fiber having core-cladding structure .…”
