Magnetic resonance imaging has been used to visualize moisture distribution in cut-pile nylon carpet following the dyeing and finishing process and before it enters the dryer. At moisture levels typical of those following hydro-extraction (i.e., ~70%), water is concentrated within the carpet yarns of the backing. From optical micrographs, it can be seen that this is the same region as the small...
it has been stated that near work can cause myopia progression1-3 and carpet weaving is included in that frame of work. carpet weaving is a meticulous and very fine handwork which is performed from a very near distance for hours and hours each day and for many years in life-time. a precise visual attention and concentration is needed in this job. in this current issue of iranian journal of ...
BACKGROUND There is increasing interest in using chemicals measured in carpet dust as indicators of chemical exposures. However, investigators have rarely sampled dust repeatedly from the same households and therefore little is known about the variability of chemical levels that exist within and between households in dust samples. RESULTS We analyzed 9 polycyclic aromatic hydrocarbons, 6 poly...
Inspired by the natural phenomenon of strong attenuation of oceanic surface waves by muddy seafloors, the Theoretical and Applied Fluid Dynamics Laboratory at the University of California, Berkeley, has recently investigated a mud-resembling synthetic compliant seabed carpet (so called Wave Carpet), composed of linear springs and generators, that can be used as an efficient wave energy conversi...
One summer evening in 2004 our 11 year old son went to bed after various delaying tactics—arguments about friends who stay up later, forgetting to brush teeth, coming down for a drink of water. Shortly afterwards the dining room door opened. In he came, cupping his bleeding nose in one hand as he gripped the bridge of the nose with the other. We led him to the kitchen sink to help him clean up ...
Currently, carpet companies assess the quality of their products based on their appearance retention capabilities. For this, carpet samples with different degrees of wear after a traffic exposure simulation process are rated with wear labels by human experts. Experts compare changes in appearance in the worn samples to samples with original appearance. This process is subjective and humans can ...
24 Nanoscale ceramic surface modification of textiles by atomic layer deposition R ecent opportunities to merge traditional inorganic materials processing with organic fibrous textiles are creating new possibilities in electrical, optical and mechanical applications for textiles. Textiles are made of low-cost natural or synthetic fibers and have unique flexibility, strength and durability with ...
