A Study on the Effect of Plasma Treatment on Thermal Comfort Properties of Cotton Fabric

Pages : 8
Book Description
In this study, the influence of plasma treatment on the thermal comfort properties of cotton woven fabric has been investigated. The woven fabric sample was treated with three types of plasma, namely, air, argon, and oxygen plasma. The investigation was done with various parameters like treatment time, the distance between the fabric sample and electrode, and the frequency of the plasma process. It is observed that the air permeability of the fabric has a linear relationship with the distance of the sample and better air permeability achieved in air plasma. Also, the air permeability inversely related to time and frequency. The thermal resistance and water vapor permeability decreased with the distance and increased with the time and frequency. Similarly, the thermal resistance and water vapor permeability of cotton samples were enhanced in oxygen plasma treatment.

Thermal Protective Clothing for Firefighters
Author: Guowen SongPublisher: Woodhead Publishing
ISBN: 0081012861
Category : Technology & Engineering
Languages : en
Pages : 244
Book Description
Thermal Protective Clothing for Firefighters explores the materials, design, and usage of thermal protective clothing. The characteristics of fire hazards are discussed in detail, and the thermal environments faced by firefighters in these fire hazards are also examined. The different types of potential burn injuries and the heat stress that occurs to firefighters’ bodies when exposed to such thermal environments are analyzed. Furthermore, the development of various high performance fibers and fabrics for thermal protective clothing is discussed. The test methods and existing standards to evaluate the thermal protective and physiological comfort performances of the fabrics and clothing are critically reviewed. Recent developments in the field of fire- and heat-resistant materials have led to significant improvements in thermal protective clothing. In parallel with this, the complexity and risk levels of fires, especially in industrial-storage facilities, and developments in health and safety cultures have increased the demand for high-performance heat- and flame-resistant clothing and equipment, designed to mitigate skin burn injuries and reduce risk of death from fire hazards. Throughout the work, the gaps and limitations in existing test methods and standards are identified, and approaches are recommended for the development of enhanced test methods. Scenario modeling and its implications for firefighters’ protective clothing is discussed, and various factors affecting performance are established. Finally, various key issues related to thermal protective clothing are addressed to guide the future research in the field of thermal protective clothing for firefighters. This book will help materials-textile engineers to develop high performance thermal protective clothing that can enhance the protection, safety, and comfort of firefighters. Offers a helpful guide to the successful specification and design of high performance protective clothing to meet the high standards of today's regulatory framework Introduces the new materials technical innovations that are transforming fire protective clothing Explores the role of clothing from the operational perspective, including technical innovations Offers a critical review of the test methods and existing standards to evaluate the thermal protective and physiological comfort performances of the fabrics and clothing
Effect of Yarn and Fabric Structure on Air Permeability

Book Description
Permeability is the dominant functional characteristic of parachute cloth. Excessive permeability reduces deceleration rates, while too low a permeability can cause excessive loads on both the chute and the object being decelerated. High speed objects and attendent high pressure drops on chutes have necessitated the development of more rational understanding of the factors affecting permeability. The problem is very complex because of: (a) Variety of types, and thus their effects, of geometrical factors, (plain weave cloth alone, ideally, has 11 variables of construction, add to this the effects of yarn structure). (b) The type of flow through fabrics can and does change from "simple stream-llne" flow to turbulent flow at high pressure drops. (c) The nature of the "orifice" in fabric flow changes with pressure drop i. e., crimp interchange under biaxial tension enlarges the fabric "pores" and can increase the flow between yarns, while increases in turbulence and flow between fibers can assume importance at high pressure drops.
