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 ..

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..

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..

Effect of Staple Strength on Spinning Performance and Yarn Quality of Superfine Wools

A processing trial was conducted at CSIRO comparing three batches of 17 µm, superfine fleece wool, collected from sale lot samples and matched for fiber properties but not staple strength. The three batches were compiled from auction display samples to have average staple strengths of 24, 32 and 43 N/ktex and were converted to top, yarn, ..
