The presence of defects in cold mercerizing of cotton goods led to the creation of a new method, called hot mercerizing in which caustic soda solution is used at a high temperature. Hot mercerizing is successfully used in cotton blended with some other fibers. In cotton/polyester blend fabrics, this treatment serves a dual purpose: subjectively, it imparts a silklike soft handle to the po...

In this research, fire and radiant heat protection and thermal comfort properties of cotton/nylon-Kermel blended woven fabrics, were utilized to predict the thermal comfort and protection limit of this fabric structure based on Woo and Barker developed model. The results showed that the porosity, the air permeability and the thermal resistance increased with Kermel fiber blend ratio. Conversely...

Learning is enhanced by the physical and social technologies typically used in distance education. Students in distance programs typically have access to tools that allow them to repeat lectures and interact with their fellow students and faculty. Students in all classes, including face-to-face and blended courses, benefit from having similar tools and technologies available. This article will ...

The concept of cooperation and distribution as known from the area of grammar systems is introduced to graph grammars; more precisely, to hyperedge replacement (for short, HR) grammars. This can be seen as a modest approach to controlled HR. Two diierent derivation modes are considered, the so called t-mode and the =k-mode. For the t-mode it is shown that the class of hypergraph languages obtai...

Polymer blends are formulated by mixing polymers with different chemical structures to create new materials with properties intermediate between those of the individual components. While Flory– Huggins ~FH! theory explains some basic trends in blend miscibility, the theory completely neglects the dissimilarity in monomer structures that is central to the fabrication of real blends. We systemati...

Amorphous poly(vinyl phenol) (PVPh) is introduced into poly(butylene succinate-cobutylene adipate)/poly(L-lactic acid) (PBSA/PLLA) blends via solution casting. Fourier transform infrared spectroscopy (FTIR) analysis verifies that intermolecular hydrogen bonding formed in PBSA/PVPh/PLLA blends. The miscibility between PBSA and PLLA is improved with PVPh incorporation as evidenced by approaching ...

R progress in the synthetic chemistry of supramolecular assemblies has created many new structural types. With the proliferation of new structures has come increasing interest in the properties and behavior of these assemblies. Does the cooperativity of constituent components lend an assembly new properties distinct from the components themselves? Do the properties of an assembly make it suitab...

The law of temporal hierarchies of the biological world allows us to pick out of the biomass quasiclosed thermodynamic systems of a specific hierarchy. The use of this law of Nature as applied to supramolecular structures of organisms allows us the opportunity of using the methods of equilibrium supramolecular thermodynamics in the examination of open living systems. It has been proven that the...
