Thermal Characterization of Innovative Sustainable Building Materials from Wool Textile Fibers Waste
This chapter aims at exposing the development of two research projects that started in 2016 University Bogota Jorge Tadeo Lozano, which are case studies living laboratories. From them arise pieces textile design and sustainable fashion following a systemic approach, by means methodology includes recognition fibers, their material its DNA, cultural analysis re-signification, order to establish p...
Abstract A new class of sustainable building composite materials is developed, made out recycled fibers waste, sand from crushing inert waste and lime. The come abundant available bio-based or mineral such as cellulose, glass wool, rock wool. comes used instead river which a resource under shortage. Lime is, like the other two constituents, locally. targeted performance minimizing environmental...
The structure and properties of chicken feather barbs makes them unique fibers preferable for several applications. The presence of hollow honeycomb structures, their low density, high flexibility and possible structural interaction with other fibers when made into products such as textiles provides them unique properties unlike any other natural or synthetic fibers. No literature is available ...
Pulicaria gnaphalodes has various biological activities and is used as an herbal plant in traditional medicine. The major components of the aqueous extract of this plant are flavonoids, terpenoids and phenolic compounds which could be a good candidate for dyeing of wool fibers. In this study, the aerial part of Pulicaria gnaphalodes plant was extracted and used for the colorat...
We are interested in numerical methods for computing the effective heat conductivity of fibrous insulation materials, such as glass or mineral wool, characterized by low solid volume fractions and high contrasts, i.e. high ratios between the thermal conductivities of the fibers and the surrounding air. We consider a fast numerical method for solving some auxiliary cell problems appearing in thi...
Instrument Type Detection Umit (mg/L) Introduction Because of the difficulty and cost of treating certain types of wastes, pollution prevention has become an important method of environmental protection for the textile industry.'* Extensive attention has been focused on the selection and use of chemical specialties and their role in pollution prevent i ~ n . ~ ~ Proper raw material selection, p...
Asbestos is reported to cause pulmonary fibrosis, and its use has been banned. We examined the biopersistence and histopathological effect of rock wool (RW) fibers in rat lungs by a nose-only inhalation exposure study. Twenty-four rats were exposed to RW fibers for 6 h daily for 5 consecutive days. Six rats each were sacrificed shortly and 1, 2, and 4 wk after exposure, and the fiber numbers an...
