Thermal Analysis and Differential Solubility of Polyester Fibers and Yarns

The differential sdlubility and thermal analysis of three kinds of polyester fibers designed for rotor, worsted ring, and carded ring spinning are measured. Poly(ethylene terephthalate) yarns are obtained through the three processes and then analyzed. Using a thermomechanical analyzer, the thermal transitions of the different yarn types a..

Electrical Properties of Laminates Made from a New Fabric with PP/Stainless Steel Commingled Yarn

A new rotor-wrapping-twister is used to produce new yarns comprising stainless steel filaments, polypropylene nonwoven tapes, and reinforcing filaments. Rapier looms are used to weave commingled fabrics from these yams. The electrical properties of thermo plastic commingled laminates are investigated for the commingled fabrics and for lam..

Modeling and Computer Simulation of the Compressional Behavior of Fiber Assemblies: Part I: Comparison to van Wyk's Theory

A model is presented that allows prediction of the properties of a fiber assembly under compression from the physical properties of its component fibers, taking into account both static and kinetic friction. Unlike previous models, this model is not based on the assumed behavior of idealized bending elements. Computer simulations are run ..

Chemical Structural Investigation of the Cotton Fiber Base and Associated Seed Coat: Fourier-Transform Infrared Mapping and Histochemistry

Fourier-transform mid-infrared mapping and histochemical staining are used to reveal the location and relative importance of chemical components involved with the base of cotton fibers and their associated seed coat. These two complementary techniques are focused on the nature of the chemical components that hold cotton fibers at their ba..

Objective Evaluation Equation for the Appearance of Swinging Flared Skirts

To develop an objective evaluation equation for the aesthetic appearance of swinging flared skirts, subjective appraisals are obtained from 29 girls, aged 20 to 22, by the paired comparison method. The subjective values are regressed with basic mechanical parame ters and the vibrational parameters of the fabrics from which the skirts are ..

Influence of Flame Retardant on Manufacturing Carbon Fiber Absorbents

A carbon fiber absorbent is prepared using a rayon-based fabric as a precursor, and a composite flame retardant of ammonium sulfate and dibasic ammonium phosphate as a pretreatment agent is used to prepare the carbon fiber absorbent in a continuous three- stage process in a high temperature environment of oxidation, carbonation, and activ..

Uniaxial Tensile Properties of Yarns: Effects of Moisture Level on the Shape of Stress-Strain Curves

With the aim of clarifying the complex shapes of the stress-strain curves of yams such as wool and silk and improving the reproducibility of the experimental results achieved through their mechanical characterization, nylon 6,6 yams consisting of one, three, nine, and thirty filaments are selected as a modeling system. Moreover, the uniax..

Luminescence and Mechanical Properties of Photoluminescent Core Bicomponent Fibers

Photoluminescent fibers with a sheath-core morphology are produced to impart good mechanical properties. Both photoluminescent and mechanical properties are examined for these fibers with respect to photoluminescent pigment concentrations in the core, draw ratios, and polymer types. The photoluminescent pigment concentration in the core o..
