Polyester yarn spun over a range of wind-up speeds and subsequently drawn at 373 K has been characterized by differential scanning calorimetry. Samples that are constrained from shrinking during the thermal scan respond differently than samples that

The mechanism of oxidative stabilization of acrylic fibers is characterized by two limiting cases which are determined by the fiber chemistry, the reaction conditions, and the diameter of the filament. These limiting cases correspond to diffusion-lim

The crystallization event in a number of thermotropic polyesters containing hydroxybenzoic acid, naphthalene dicarboxylic acid, isophthalic acid, and hydroquinone has been followed by a variety of techniques including optical microscopy, calorimetry,

When acrylic fibres are heat treated for various times at 220 to 250° C, they form dark, insoluble structures of uncertain chemical character which are inert to many strong oxidizing and reducing agents. The heat-treated fibres are, however, rapidly

Ion etching of amorphous and semicrystalline fibres produces structures which can be observed in either the transmission electron microscope or the scanning electron microscope. The structures so produced have previously been identified as resulting

Polyester yarn spun over a range of wind-up speeds has been characterized using differential scanning calorimetry. Samples prohibited from shrinking during the thermal analysis show slightly smaller heats of fusion and crystallization and reduced col

The heat associated with drawing of poly(ethylene terephthalate) fiber is estimated on the basis of equations developed in the literature on films undergoing deformation by neck propagation. The deformation process is divided into two steps: neck pro

Removal of the ultrahigh molecular weight fraction in high-density polyethylene by hydrodynamic crystallization and analysis of the subsequent drawing behavior leads to the conclusion that the small portion of extremely long chains present in polymer
