An ecological approach has been obtained by using natural dyes and mordant for dyeing process. Silk fabrics dyed using natural mordants: powder of sour pomegranate and sweet pomegranate and mixture them. A beautiful red color were obtained by using theses mordants. The color of dyed silk fabrics was investigated in CIE Lab L, a and b and K/S values. Finally, all dyed fabrics were tested for was...

The current commercial application of ink-jet reactive inks to cotton fabrics has been through pre-treating with pad liquor prior to printing. In This study made an effort to provide a single phase ink-jet printing process for printing cotton fabric using the novel cationic reactive dye in ink’s formulation. Cotton fabric was printed upon with the novel cationic reactive dye and commercial anio...

Loose fitting garments can accommodate a greater number of different bodyshapes but close fitting garments cannot. The assumption is that stretch garments will automatically stretch in the right places to give an acceptable fit and provide comfort as well as ease of movement. But this is a fundamental misunderstanding of stretch fabric characteristics and garment pattern geometry. To date the g...

The aim of this paper was to study the relationship between pressure drop and superficial velocity for fabrics used in Through Air Drying and also for perforated plates. Experiments were performed to measure this relationship and the experimental data was then compared to different theoretical models. It was hard to get good agreement between the models and the experimental data for the perfora...

This paper presents an extensive transistor sizing analysis for regular transistor fabrics. Several evaluation methods have been exploited, such as DC simulations, ring oscillators and single-gate open chain structures. Different design aspects are addressed taking into account stacked transistors, cells with drive strengths and circuit critical paths. The performance degradation of using regul...

Weight reduction increased the amount of deposited polypyrrole (PPy) on the polyester (PET) fiber surface, leading to a considerable decrease in electrical resistance and improved heat generation capacity for the PPy coated PET fabrics. Application of DC voltages to an insulated roll of PPy-coated fabric increased the temperature to about 90 oC. This showed the suitability of these fabrics for ...

Bleaching effect of cotton fabrics using hydrogen peroxide produced by glucose oxidase enzyme from Aspergillus niger has been studied. It is observed that enzymes are highly active at acidic pH under room temperature in terms of peroxide release during the reaction. Incomplete conversion of glucose by the enzyme results in discolouration of the reaction bath and the fabrics under alkaline pH co...

Firefighting is a dangerous occupation that relies heavily on the effectiveness of protective clothing. This type of protective clothing must resist heat, flame, rough surfaces, and sharp objects as well as protect the wearer against biological/chemical surfaces. In order to address these issues, a survey was administered to firefighters to determine necessary changes that would make the presen...
