Static Dissipation Mechanism in Carpets Containing Conductive Fibers

The mechanism of static charge dissipation in carpets containing electrically conductive fibers is investigated. Incorporating conductive fibers in a carpet, even as isolated conductors, results in greatly reduced static charge accumulation on people as they walk across the carpet. Results of this work show that static charge dissipation ..

Modifying an Existing Numerical Shade Sorting System Through Cluster Analysis

Our previous study compared the effectiveness of Clemson color clustering (CCC) shade sorting, originating at Clemson University, with a shade sorting process called K-means, originating at the Indian Institute of Technology. We proved that these two methods were suitable for shade sorting since their performance was very much alike. Thes..

Objective and Subjective Analysis of Knitted Fabric Bagging

In this study, fabric bagging tests are performed on a set of knitted fabrics that vary in design, tightness factor, and blend ratio. The relationships between residual bagging height (R residual) obtained from the fabric bagging test and the mechanical characterization determined from the KES-FB system are presented and discussed. The wo..

Part II: Wear Model of Loop Pile Carpet

A two-stage wear mechanism in a loop pile wool carpet is confirmed by current experi mental studies. A loop pile wear model is then developed on the basis of the two-stage wear mechanism. This model meets the initial and final conditions of carpet wear and shows that a loop pile construction of similar pile density has a longer life than ..

Part I: Wear Model of Cut Pile Carpet

Modem probability fracture mechanics forms the foundation of Carnaby's carpet durability theory. On the basis of this theory, mathematical models have been developed to predict the wear life of wool cut pile carpet. In this paper, the existing models are upgraded to provide an accurate mathematical expression of Carnaby's theory, in line ..

Laboratory Test Methods to Measure Repellency, Retention, and Penetration of Liquid Pesticides Through Protective Clothing. Part I: Comparison of Three Test Methods

In the last three decades, different test methods have been used to assess the level of protection provided by various textile materials against liquid pesticide penetration. Of these, the ISO 6350/EN368 gutter test is currently used to screen garment materials for certification of type 6 personal protective equipment (PPE) in Europe. The..

Cathodic Reduction of CI Acid Red 27 and CI Reactive Black 5—Basic Investigations of Decoloration of Textile Waste Water

Reductive decoloration of CI Acid Red 27 and CI Reactive Black 5 is achieved by cathodic electron transfer. The stoichiometry of the dyestuff reduction is studied with redox titrations using an Fe(II)-TEA complex as the reducing agent. CI Acid Red 27 is reduced to the corresponding amines at room temperature, while full reduction of CI Re..

Variation of Longitudinal Modulus with Twist for Yarns Composed of High Modulus Fibers

Variations of longitudinal and transverse moduli with twist for twisted yarns and twisted yarn-resin composite strands composed of fibers covering a wide range of tensile moduli are investigated using a sonic pulse propagation method. For twisted yarns composed of fibers relatively low in tensile modulus, the longitudinal modulus decrease..
