The synthesis and examination of Azo dyes derived from novel couplers
… p. m. r. spectra'of the dyes have been noted. Fastness properties of the dyes'on polyester are given. Light fastness ratings are generally low, although the presence of a Y-heteroatom in the six-membered terminal amino ring is advantageous, resulting in values approaching those of the …

Oxidationshaarfarbstoffe als alternative Farbstoffe für das Färben von Wolle
… solubility turned out as a disadvantage for the fastness. With the system 1,10-bis-(2,5-diaminophenyl)-1,4,7,10-tetraoxadecane/1,3-bis-(2,4-di-aminophenoxy)propane a deep dark-blue black colour could be achieved. The structure of the high-molecular oligomers of this dye could not be determined. …

Application of natural dyes in textile industry and the treatment of dye solutions using electrolytic techniques
… the dyeing process without mordants. The colour fastness to wash and light (both natural and artificial sun light) of these natural dyes were also assessed. The results showed that out of the 54 dyestuffs studied, 32 plants are potentially able to produce marketable natural dyes. These dyes …

Färben im Ultraschallfeld sowie aus überkritischem Kohlendioxid als alternativem Färbemedium
… wool in deep shades and with high levelness and fastness properties in a water-free dyeing process using supercritical carbon dioxide instead of water. To match the fastness standards of today it is necessary to use fiber-reactive disperse dyes or mordant dyes on a pre-mordanted wool fabric. …

Development of optimal dyeing methods with natural dyes for environmentally friendly hemp textile
… process for natural fibers that improved wash fastness. It focused on the formulation for dyeing with natural colorants, optimization of the dyeing techniques, and development of the best procedure. This research used a full factorial design of experiments to best optimize the dyeing procedure. …

Aplication of circular economy to manufacture sneakers from the banana pseudostem yarn
… strength with no appreciable damage. The rub fastness result is dry 5 and wet 5. The thickness of the sole is 19.4 mm. The Sole flexural strength does not have signs of damage, and the resistance of the shear-floor joint is 8.9N/mm.

The Built Environment and Material Culture of Ireland in the 1641 Depositions, 1600-1654
… timber and destroyed the wood kerne-infested fastness, and new houses erected on plantation settlements rattled a landscape still speckled with the wattle huts of its native inhabitants. Using the 1641 Depositions as the core of this dissertation, this research endeavours to contextualise …

The chemistry of some derivatives of pyrrolidine green and pyrrolidine violet
… substituents have been interpolated. The light fastness of some Pyrrolidine Green derivatives has been measured and the commercial implications assessed.

Preparation and characterisation of inks for let printing onto textile materials
… a high quality print which offered the required fastness properties of a textile print whilst maintaining a soft fabric handle. The cross-linking mechanism/properties of the Synthappret BAP were fully characterised. It was found that Synthappret BAP underwent rapid self cross-linking at elevated …

Evaluation of Pilot and Quadcopter Performance from Open Loop Mission Oriented Flight Testing
… to identify system complexity, stability and fastness based on level of autonomy as well as pilot performance based on experience level. Apart from time and frequency domain analysis, Cooper-Harper rating scale is used by the pilots to rate the UAV based on ease of control. Along with time and …

Plasmagestützte Oberflächenmodifizierung von Polypropen
… dye solutions. Another reason is the low wet fastness, as a result of the minor ability of PP to fix the dyestuff within the fibres. Consequently, a process has to be applied, which increases the surface wettability and additionally, improves the dyestuff-fibre interaction. Suitable …

Efecto de la glicemia materna en la monitoría electrónica fetal
Introducción: Después del ingreso de la monitoría fetal electrónica como estudio de bienestar fetal, se ha considerado por décadas que un aporte de carbohidratos a la gestante antes de la realización de la monitoría fetal influye en el reporte pero existen estudios que consideran que los niveles de …
