The Effect of Salt Splash on Nylon 6,6
… of the most common environmental exposures that nylon undergoes, when used for automotive applications, is that of salt splash, which commonly occurs during winter driving. This study looks at the effect of various salts (NaCl, KCl, CaCl2) on the thermal and mechanical properties of nylon when …

Nylon-6,6 oligomers : Synthesis, characterization and relevance to the polymer.
… for the synthesis of selected oligomers of nylon-6.6 and trial syntheses using these routes. Once a general synthetic route to pure oligomers is available it can be applied to the preparation of oligomers of increasing length, while maintaining purity for future characterization studies. It …

Supercritical Fluid Extraction of Nylon 6,6 Fiber Finish and Oligomers
… the quantitation of finish and oligomers from nylon 6,6 fibers. The effects of pressure, extraction temperature, modifier percentage, static extraction time, and dynamic extraction time on the supercritical fluid extraction efficiency of nylon 6,6 oligomers were examined. Results from the SFE …

Textured fluids
… of poly(ethylene terephthalate) (PET) and nylon 6,6. The role played by liquid crystalline order (LCO) and a polydomain texture on the rheology of PPT solutions was investigated. It was found that several of the rheological phenomena commonly attributed to liquid crystalline order in …

The compounding of short fibre reinforced thermoplastic composites
… the properties of carbon and glass reinforced nylon 6,6. Use is made of computer programs to predict properties, assess compound quality and estimate fibre-matrix bond strength. Investigations indicate that the presence of reinforcing fibres with enhanced lengths does not result in the …

Effects of fiber type on the tribological behavior of polyamide composites
… aramid, and carbon fiber-filled polyamide (Nylon 6,6) composites serve as models for understanding friction and wear processes encountered when polymer composites are used in tribological applications. Experimental results not only include measurements of friction and wear, but surface …

Polymeric Adsorption of Estrone from Water and Photocatalytic Degradation by Zinc Oxide
… at relatively high concentrations. Polyamide (Nylon) 6,6 microfiltration membranes were used as a functional polymeric adsorbent to capture low levels of estrone from water. The process is driven by a hydrogen-bonding mechanism between amide groups in polyamide 6,6 and phenolic hydroxyl groups …
