Bk. Behera et A. Pakhira, STUDIES ON STRUCTURAL-CHANGES IN AND DAMAGE TO POLYESTER-FIBER CONTINUOUS-FILAMENT YARN DURING SIZING, J TEXTILE I, 89(3), 1998, pp. 515-521
This paper presents an account of mechanical, thermal, and thermomecha
nical damage taking place during the sizing of polyester-fibre continu
ous-filament yarns. Structural changes due to axial, transverse, and t
angential forces on the yarn during sizing are studied by using X-ray-
diffraction and birefringence techniques; Surface damage to the yarn i
s examined by the scanning electron microscope. The effect of a squeez
e load on fibre damage is also investigated. The study is extended to
textured and microdenier multifilament yarns.
