Investigating the Preparation and Properties of DiesAim To go over the preparation and properties of come aparts.Introduction- Dyeing is a suffice of colouring materials, much(prenominal) as textile fibres,so that the colouring matter becomes an integral break apart of the fibre.Dyes, or tarnishstuffs, ar soluble compounds that can be either imprisoned and retained by the fibre or chemically combined with it.Dyes are generally fast, that is, they retain their colour in thefibre through bulge out the textile-making process and under exposure tonormal wear, including sunlight, water, and detergent washing.(Textile dying)- Dyes can be sort as either natural or synthetic. The onlynatural sully still use on a large scale is logwood, which imbues silk,wool, cellulose acetate, and nylon with a deep 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 Encarta Reference Library 2003 introductory WorkAbout 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 immix with hot water, the dye spread out quickerand was brighter than with cold water, repayable to the fastness of movingmolecules in the hot water. No real outcome was establishedhowever, for the experiment was done to give a fair topic of how dyeswork. PredictionMy promiseion is that if the amount of water in the die is reduced,the die forget be stronger, and if it is increased, the die will becomeweaker. I also think that with salt as a mordant, 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 diagnoseThe apparatus used will be Coffee, loss Cabbage and Red wi ne (to carry out experiment) Board Cleaning Cloth (to say dye in) Salt and sugar (as fixatives, to grip dye to fabric) Measuring piston chamber (to nib amount of water, dyes and mordant) Old pot (to dye fabrics in) Gloves (So that hands do not interfere with the experiment, and not to stain them) Beaker (To grind dye sources in) Thermometer (to measure the temperature of water) Scale (To measure the mass of the dyes and fixatives) Stopwatch (To count the simmering time)Carrying out the Investigation Material (dye source) is broken into small pieces in the beaker (or
