Definitions
- an alkaline material is added to promote a chemical reaction between the dye molecules and atoms of the cellulosic fibres.
- the dye combines chemically with the cellulosic material.
- the dye, so bonded, will not wash out of the cellulose. This is known as a “wash-fast” dyeing. Without the “salting out", which increases the substantivity of unreacted dye molecules with the fibre, much of the dye would not have reacted with the fibre and the colour would have been lost.
- a fibre-reactive dye molecule is made up of a colour portion and a chemically-reactive portion.
- the chemically-reactive portion reacts with an hydroxyl group on the cellulose macromolecule under alkaline conditions to form a chemical bond between the cullulosic material and the colour portion of the dye molecule.
- electrolytes in the form of neutral salts are added to the dyebath to enhance the substantivity of the dye molecules on to the cellulosic material fibres, before chemical reaction between the hydroxyl groups and the chemically-reactive portion of the dye takes place.
- a good yield in dyeing depends on causing a large proportion of the dye molecules to absorb, or "salt out", on to the cellulosic macromolecules, before chemical reaction occurs. This must then be followed by the addition of an alkaline material which promotes the chemical reaction between the cellulosic fibre and the dye molecule and minimizes the reaction between dye molecules and water molecules.
- sodium hydroxide alone or in combination with soda ash sodium carbonate
- sodium carbonate alone sodium carbonate alone
- trisodium phosphate sodium bicarbonate
- tripotassium phosphate alone or in combination with a strong base such as potassium hydroxide and/or sodium hydroxide.
- JP-A-56-043490 discloses a resist or discharge printing paste containing, as indispensable ingredients, an alkali metal salt, fine silica powder and an alkaline compound which is preferably sodium or potassium carbonate or hydroxide or sodium or potassium phosphate.
- FR-A-2148294 states that known acid binding agents used in dyeing with reactive dyestuffs are caustic alkalis, sodium carbonate, sodium bicarbonate, trisodium phosphate and sodium metasilicate.
- the present invention provides an alkalizer, suitable for use as a textile bath additive which comprises a water solution containing tripotassium phosphate, characterised in that the alkalizer comprises a premixed liquid composition suitable for direct addition to a textile bath and being formed from, by weight: Tripotassium phosphate 5-45% Potassium hydroxide and/or sodium hydroxide 0-10% Potassium carbonate and/or sodium carbonate 2-10% Water Balance
- This invention also provides a method of controlling the alkali content of a reactive dye bath process, which comprises:
- K3PO4 tripotassium phosphate
- KOH potassium hydroxide
- NaOH sodium hydroxide
- K2CO3 potassium carbonate
- Na2CO3 sodium carbonate
- the combination of these ingredients can be made as a convenient direct textile bath additive in the form of an aqueous solution, preferably with a total solids ranging from about 10% up to approximately 50% by weight of the solution.
- the limit of lower percentage is dictated by the economics of having a more concentrated solution for transportation.
- the upper limit of concentration is determined by the temperature at which a mixture can be stored. For storage above 10°C, the concentration can be even higher.
- the liquid alkalizer of the present invention can be formulated over a wide range of concentrations. It has been found that the combination of the ingredients of the present invention can be made in aqueous solutions, preferably with the total solids ranging from about 10% to up to approximately 50% by weight of the solution. The lower limit is dictated mainly by the economics of having a more concentrated solution for transportation, while the upper limit of concentration is determined by the temperature at which a mixture can be stored. For storage above 10°C, the concentration can be higher.
- potassium hyroxide (or equivalent sodium hydroxide) is optional, it is a preferred component in that it functions in the dye-bath to neutralize acidity.
- NaOH may be fully or partially substituted to an equal total amount for KOH and Na2CO3 may be fully or partially substituted to an equal total amount for the K2CO3.
- a typical method used for making the liquid alkalizers of the present invention is as follows: To prepare a formulation of the present invention, the appropriate amount of water is first added to a vessel. The K3PO4 can be added with stirring and, when dissolved, the desired amount of KOH is then added. Next, Na2CO3 or K2CO3 is added. The alkalizer mix is stirred and drained into drums after cooling below 40°C. The drummed material is the alkalizer ready for use or sale.
- the liquid alkalizer can be prepared using phosphoric acid (H3PO4), a 45% solution of KOH and a 47% solution of K2CO3, all of which are commercially available.
- H3PO4 phosphoric acid
- KOH 45% solution of KOH
- K2CO3 47% solution of K2CO3
- the water content of the alkalizer of the present invention can therefore originate from water introduced as such, or from water introduced as part of an aqueous solution of the other ingredients, or partly from one source and partly from the other.
- the ingredients would be added in the same order as listed, using cooling as necessary to keep temperature below 70°C. Cool to 40°C and pack into drums.
- Formula (F) of TABLE II would be made as follows: 8.1% Water 61.8% KOH - 45% solution 21.6% H3PO4 - 75% solution 8.5% K2CO3 47% solution Add ingredients in the order listed, using cooling to keep the temperature below 70°C. Cool finally to below 40°C and pack into drums.
- the alkalizer formulations of the present invention may be used for the dyeing of cellulosic materials with fibre-reactive dyes as follows, using an Ahiba Laboratory dyeing apparatus to carry out the dyeing: Into a suitable dyeing beaker of about 230 ml volume, 100 ml of water at 80°F (27°C), 7 grams of sodium chloride, 0.05 grams of surfactant, Tanaterge LV (Sybron Chemicals, Inc), and 0.3 grams of Remazol REd F3B Fibre-Reactive Dye (American Hoechst) are added. Place the beaker in the water bath of the Ahiba device. Mount a swatch of 100% woven cotton on an agitator holder and insert it into the beaker.
- the agitator is capable of simultaneous vertical and rotational motion.
- the cotton swatch in held below the surface of the liquid at the lowest point of the agitator movement.
- the Ahiba bath is held at 80°F (27°C) while agitating for 10 minutes.
- about 0.5 gm of liquid alkalizer is added and the bath is agitated for 10 minutes.
- the bath is then heated to 140°F (60°C), and agitated for 45 minutes.
- the cotton swatch is then removed from the bath, washed with cold water, then hot water, then soap solution, then hot water and finally cold water.
- the swatch is then dried and the dyed colour evaluated.
- Formula (G) is a Sybron Chemicals, Inc. commercial alkalzier sold under the trademark ALKAFLO®. Using the ALKAFLO alkalizer as the reference standard alkalizer, the colours of 100% cotton swatches are compared and tested by means of the ACS Spectro Sensor (Applied Color Systems Inc.).
- the dry dyed cotton sample was folded over twice and then placed in the sample holder of the ACS Spectro Sensor. A scan of the sample is then run automatically and the spectro data automatically stored in the IBM PC computer which is connected to the ACS Sensor.
- the cotton sample which was dyed using ALKAFLO liquid alkalizer as the alkalizer is arbitrarily taken as the standard, with the strength reading set at 100.
- the spectro data of the other samples are compared automatically by the IBM PC and strength results are printed out.
- Readings of 100 are equal to standard. Readings above 100 show greater dye strength than standard. Readings below 100 show weaker dye strength than standard.
- a small amount, such as 0.1%, of sodium gluconate or other suitable sequestering agent may be added to any of the above formulations, to prevent the formation of precipitates caused by impurities in the water or chemicals used.
