Patents or Patents Pending

An Aluminum Nitride (AlN) MEMS resonator technology has been developed, enabling massively parallel filter and oscillator arrays on a single chip. Low loss filter banks and resonator arrays covering the 10MHz10GHz frequency range have been demonstrated, as has monolithic integration with inductors and CMOS circuitry. The high level of integration enables miniature multi-band, spectrally-aware a...

Continuous Improvement in Yarn Dyeing

pdates on yarn dyeing technology U were shared among the 83 participants in the AATCC symposium held at Southern Pines, N. C., in April. The symposium included 11 presentations, problem solving sessions and a discussion session on the challenges of package dyeing microfibers. Developed by AATCC‘s Committee on Yarn Dyeing Technology, the two-day program offered registrants ampleopportunity to co...

Lipid Role in Wool Dyeing

The textile industry uses different fibers obtained from various animals, of which the wool from domesticated sheep Ovis aries is commercially the most important. Dyeing is one of the most important finishing procedures of wool processing. It almost invariably involves absorption of water-soluble colorants from aqueous solutions by the fibers. Diffusion is the process by which the colorant mole...

Textile Dyeing Wastewater Treatment

Textile industry can be classified into three categories viz., cotton, woolen, and synthetic fibers depending upon the used raw materials. The cotton textile industry is one of the oldest industries in China. The textile dyeing industry consumes large quantities of water and produces large volumes of wastewater from different steps in the dyeing and finishing processes. Wastewater from printing...
