The Application of the Volumetric Subdivision Scheme in the Simulation of Elastic Human Body Deformation and Garment Pressure

The simulation of elastic human body deformation and the garment pressure distribution when wearing tight-fitting clothing is critical for the biomechanical design of functional apparel products. In this paper, we propose a new geometric interpolatory volumetric subdivision scheme over the hexahedron lattice to simulate the deformation of..

Comfort Properties of Heat Resistant Protective Workwear in Varying Conditions of Physical Activity and Environment. Part II: Perceived Comfort Response to Garments and its Relationship to Fabric Properties

Controlled garment wear trials are used to evaluate comfort response to a well- characterized set of heat-resistant workwear materials. Multiple categories of perceived comfort reactions to garment wear in diverse conditions are explained in terms of measured fabric properties assessed in Part I. The important role of fabric surface chara..

Comfort Properties of Heat-Resistant Protective Workwear in Varying Conditions of Physical Activity and Environment. Part I: Thermophysical and Sensorial Properties of Fabrics

This series of studies investigates the impact of thermophysiologial and sensorial properties and end-use conditions of heat-resistant protective workwear on the wear comfort response. In Part I of this paper, material features and test methods are screened to obtain fabric characteristics that explain wear comfort effectively. Thermophys..

Sewing Needle Penetration Forces and Elastane Fiber Damage during the Sewing of Cotton/Elastane Woven Fabrics

This paper presents an experimental study of the effects of elastane draw ratio, pre-setting temperature and finishing process on the penetration forces of a sewing needle and damage to the elastane fibre during the sewing of cotton/elastane woven fabrics. Seam strength and seam opening strength of the fabrics were also determined for ass..

A Note on Jet Streaks in Hydroentangled Nonwovens

Hydroentanglement is the fastest growing bonding method in the nonwoven arena. Its strengths are good fabric aesthetics, and the lack of any complex binder chemistry with its inherent environmental concerns. Hydroentanglement is used for mechanically bonding both staple and filament nonwovens as well as being used for post-treatment of fa..

Effect of Abrasion and Absorbed Water on the Handle of Nonwovens for Disposable Diapers

Among the components of a disposable diaper, the top layer that comes into direct contact with the infant’s skin is usually made of a nonwoven fabric. Therefore, the mechanical and surface characteristics of the nonwovens are important for the health of the baby’s skin. In this study, we explored the mechanical and surface properties of..

Nanoclay and Modified Nanoclay as Sorbents for Anionic, Cationic and Nonionic Dyes

The nanoclay, montmorillonite, and some modified nanoclays were used as sorbents for nonionic, anionic and cationic dyes. From the sorption differences among the different dye and clay structures, both chemical and morphological, the sorption forces that played important roles were identified. The nanoclay could easily have a sorption cap..
