Investigating the Preparation and Properties of Dies :: Dyeing Investigations Dye Essays

Investigating the Preparation and Properties of DiesAim To investigate the cooking and properties of betters.Introduction- Dyeing is a process of colouring materials, such as textile fibres,so that the colouring matter comes an integral part of the fibre.Dyes, or sullystuffs, are soluble compounds that stop be eitherabsorbed and contain by the fibre or chemically combined with it.Dyes are generally fast, that is, they retain their colour in thefibre throughout the textile-making process and chthonian exposure tonormal wear, including sunlight, water, and detergent washing.(Textile dying)- Dyes can be classified as either natural or synthetic substance. The onlynatural dye quieten used on a large scale is logwood, which imbues silk,wool, cellulose acetate, and nylon with a robust black colour. With theexception of a few inorganic materials used in special processes, alldyestuffs used in textile applications are synthetic organicchemicals. Information taken from Microsoft E ncarta Reference Library 2003Preliminary goAbout this topic, an experiment to evaluate how quickly a dye canspread in water and the reactions between the dye and bases and acids,called Chromatography has been carried out.When beetroots were mixed with calorific water, the dye spread out quickerand was brighter than with cold water, due to the immutableness of movingmolecules in the hot water. No real conclusion was formalhowever, for the experiment was done to give a fair idea of how dyes flirt. PredictionMy prediction is that if the amount of water in the die is reduced,the die will be stronger, and if it is increased, the die will becomeweaker. I as well think that with salt as a dreary, the cloth willbecome dyed more quickly than with sugar or with no mordant at all. Asmy variable is the type of mordant, I predict that the dye colour willbe stronger with salt and weaker with no mordant.Equipment ListThe machine used will be Coffee, Red Cabbage and Red drink (to carry out experiment) Board Cleaning Cloth (to place dye in) Salt and sugar (as fixatives, to grip dye to fabric) Measuring cylinder (to beatnik amount of water, dyes and mordant) Old pot (to dye fabrics in) Gloves (So that hands do non interfere with the experiment, and not to stain them) Beaker (To grind dye sources in) Thermometer (to measure the temperature of water) get over (To measure the mass of the dyes and fixatives) Stopwatch (To count the simmering time)Carrying out the probe Material (dye source) is broken into small pieces in the beaker (or
