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..

Selecting Optimal Interlinings with a Neural Network

This paper reports on the construction of an integrated tool consisting of a neural network and subjoined local approximation technique for application to the sewing process, especially for selecting optimal interlinings for woolen fabrics. A single hidden layer neural network is constructed with five input nodes, ten hidden nodes, and tw..

Objective Evaluation of Garment Seams Using 3D Laser Scanning Technology

This paper reports on the development of an objective method for evaluating the degree of puckering in garment seams. With this method, a garment is put on a dummy and a seam is scanned by a 3D laser scanning system. The geometric surface of the scanned seam is then processed with a 2D digital filter to obtain a pucker profile by removing..

Determining Mechanical Properties of Yarns and Two-Ply Cords from Single-Filament Data: Part I: Model Development and Predictions

The objective of this research is to construct a computer model that can predict the properties of flat yams, twisted yams, and twisted cords from single-filament data. In this model, a modulus versus strain curve is obtained by taking the derivative of the average stress-strain curve from single-filament tensile tests. The distribution o..

Microstructure Organization in Para-aramid Fibers

The existence of "lateral birefringence," i.e., the difference between the refractive index for light polarized parallel to the fiber radius and light polarized perpendicular to the radius in the cross-sectional plane, combined with the existence of electron diffraction contrast "bands" in longitudinal fiber sections has led to work appea..

Warm-Cool Feeling Relative to Tribological Properties of Fabrics

When the human hand touches a garment that is at a different temperature than the skin, heat exchange occurs between the hand and the fabric, and the warm-cool feeling is the very first sensation. This transient transfer of energy depends on the contact interface between the skin and the fabric, and the contact interface depends on many m..

Transient Comfort Phenomena Due to Sweating

Of the many transient phenomena mentioned in the fabric comfort literature, two involve vapor diffusion (without liquid water transfer) from the surface of a perspiring “sweat-covered” body: the “… buffering effect of hygroscopic clothing” at the onset of sweating noted by Spencer- Smith and the “after-exercise chill” discussed by ..
