Application of Wool in High-velocity Ballistic Protective Fabrics

The protective power of typical aramid-based ballistic fabrics, when assembled into multi- layered panels designed to defeat high-velocity ballistic impacts, can be improved if wool is incorporated into the weave structure. Although the synthetic is still the primary energy- absorbent material, the wool plays a complementary role by incre..

Evaluation of the Structure of Monofilament PET Woven Fabrics and their UV Protection Properties

The importance of protection against ultraviolet radiation (UV) is increasing daily. The dependence of the UV protection level on different clothes is determined by the shape and design of fabrics, and especially by their construction parameters. The fabric structure represents an important factor which is in most cases the only condition..

Advances in Topographic Characterization of Textile Materials

All textile materials, having periodic surfaces, show horizontal and vertical repetitive unities. For this reason, different length scales have to be taken into account by interpreting topographic data measured. In this study, a topographical characterization method for textile materials at different length scales is presented and justifi..

Carbon and Glass Fibers Modified by Polysilazane Based Thermal Resistant Coating

Thermal resistant coatings of textile materials are required so that they can fulfill the high security demands in the case of resistance to fire. These coatings also improve the properties of textiles as composite materials. In this research work, a polysilazane based coating was applied on carbon filament (CF) and glass filament (GF) ro..

Effect of Diallyl Disulfide Immobilization on the Immunoreaction of Polysulfone Membranes

Diallyl disulfide (DADS) was covalently bonded to a layer of poly(acrylic acid) grafting on the surface of polysulfone (PSF) membranes. The effects of DADS bonding on oxidative stress, removal of cholesterol, triglyceride and endotoxin, and the ability of thrombus prevention were then evaluated. The surface was characterized with contact ..

Evaluating the Effects of Material Component and Design Feature on Heat Transfer in Firefighter Turnout Clothing by a Sweating Manikin

With a sweating manikin, the heat exchange efficiency through firefighter turnout clothing system from the wearer to the environment and the effects of material component and design feature on heat transfer were evaluated in a climatic chamber. Material component and design feature were varied to measure thermal insulation (It — in clo u..

The Influence of Industrial Laundering of Hospital Textiles on the Properties of Cotton Fabrics

Every laundry is determined to maintain or constantly improve the quality of its services. This quality is defined by parameters that are determined by standard methods. With the help of different industrial laundries some research on the influence of laundering procedure on the quality of laundered fabrics was conducted. For this purpose..

Fibrous Structures with Designed Wicking Properties

Fibrous structures have been designed and tested to achieve anisotropic flow properties. A structure that transports liquid in one specific in-plane direction as fast as possible was formed by parallel arrangement of continuous filament yarns in the middle layer of a three- layer structure. The top and bottom layers consisted of low areal..

A Photovoltaic Fiber Design for Smart Textiles

In this paper, the active photovoltaic fibers consisting of nano-layers of polymer-based organic compounds are presented. A flexible solar cell, including a polymer-based anode, two different nano-materials in bulk heterojunction blends as the light absorbing materials, and a semi-transparent cathode to collect the electrons, was formed b..

Effect of Strand-spacing Between Roving and Filament on Sirofil Yarn Properties

The parameters such as the angle in “V” area in Sirofil spinning system, the tension and torque of the filament and roving with different feeding spacing are theoretically discussed. The optimal strand-spacing of different spinning materials is, thus, recommended. The configuration, strength and elongation, hairiness and evenness of the..
