Water Reducing Agent Sodium Gluconate
Sodium gluconate is an organic compound that acts as a chelating agent, which means it can bind to metal ions like calcium and magnesium. This property makes it useful in concrete because it can help prevent cement particles from clumping together, allowing for better dispersion of materials and a stronger final product.
Sodium gluconate is a compound used in textile dyeing, printing, and metal surface water treatment. It is the sodium salt of gluconic acid, with E number is E576. Sodium Gluconate can also be used as water reducing agent and retarder in the construction & building industry. In textile dyeing and printing, sodium gluconate is used as a chelating agent to improve color fastness. It can also be used to clean dirt on textiles, remove surface oil, and strip agents. In two steps, which are fixation and fixation, reactive dyes are added to cotton, the exhaustion is achieved by it to resolve the negative potential of cotton and facilitate increased dye uptak.
Features of Textile Dyeing Sodium Gluconate
It is used in steel surface cleaning agent, glass bottle cleaning agent, and chelating agent in cement, electroplating and alumina dyeing industries.
These sodium gluconates have a purity of over 98% and ensure moisture content below 0.5% and impurities within 0.5% to delay the setting time to strengthen the color for fabric.
Each batch of sodium gluconate is thoroughly tested and certified to comply with international standard, and is provided in uniform packaging of different specifications.
Sodium gluconate is extremely soluble in water and can be easily dissolved in a variety of solutions and formulations in different industries. As a chelating agent, it forms stable complexes with metal ions to provide high stability and protect against oxidation.
How Sodium Gluconate Benefits Textile Dyeing
Sodium gluconate is the sodium salt of gluconic acid, produced by fermentation of glucose. It is a white to tan, granular to fine, crystalline powder, very soluble in water.
In reactive dyeing, the salt increases the affinity of the colorant to the cellulosic substrate.
- Salt increases reactive dyestuffs' exhaustion rate.
- As reactive dyestuffs have a lower affinity, more inorganic salt is required in order to accelerate absorption when using reactive dyestuffs.
- While the amount of inorganic salt used differs according to the form of dyestuff used, the amount of inorganic salt can be decreased by recently produced high-fixation dyestuffs with enhanced affinity.
Both Glauber's salt and Sodium gluconate are used in dyeing due to considerations of efficacy and expense. These two are essentially the same in terms of their position as inorganic salts because of the sodium cation active in both.
Reactive dyes are dyes with water-solubility. In the presence of Glauber's salt at neutral pH, these water-soluble dyes are exhausted on the cellulosic fibre. Under alkaline conditions, fixation is carried out in which covalent bond forms between fibre reactive sites and cellulosic content.
During fixation stage alkali is required as it acts as a catalyst between the dyestuff and the fibre. The key point is not the alkali form or quantity, but rather the bath's pH. Different alkalis, i.e. soda ash, sodium hydroxide and sodium phosphate, are used in reactive dyeing for fixation purposes.
Since this alkali imposes load on the treatment plant for effluent, alkaline agents explicitly applied during the dyeing help to change the bath pH and to obtain level dyeing. At the same time, by reducing TDS, the load on the effluent treatment plant is decreased.
The salt effect can vary according to the salt ratio in the solution. The effect of salt on the cotton dyeing process is very important. The exact and desirable shade of the object cannot be achieved without salt. The value of salt in dyeing is thus, therefore, uncountable.
Main Textile Treatment Process Steps
This process of dyeing involves several steps, including singeing, de-sizing, sourcing, bleaching, mercerizing, and dyeing. Each of these steps plays a crucial role in the overall quality of the textile product.
- Singeing and Desizing
They are the first two steps of treatment respectively. Singeing is done to remove the loose, hairy, and projecting fibers from the surface of the fabric. These fibers are often present in natural fibers, such as cotton and wool. They can make the fabric look uneven and reduce the quality of the final product. Desizing is done to remove the gummy materials over the fiber. These materials are often present in the form of starch or sizing agents used in the weaving process. This process makes the fabric softer, more pliable, and easier to work with.
- Sourcing
This is done to remove the impurities over the textile material. Sourcing is done to eliminate the impurities present in the raw material. These impurities can include dust, dirt, oil, or any other foreign particles that methods of dyeing may be present on the fabric. Sourcing is done by washing the fabric in hot water and soap or with the help of chemicals.
- Bleaching
In this step, the natural color of the raw materials is reduced. This step is done to prepare the fabric for dyeing or to achieve a specific shade of color. Bleaching is done with the help of chemicals or by exposure to sunlight. This process makes the fabric whiter and brighter, making it easier to dye and giving it a more appealing appearance.
- Mercerizing
It is an additional step and it is done to increase the strength and luster of the material. This process is done by treating the fabric with sodium hydroxide under tension. This process causes the fiber to swell and makes it stronger and more lustrous. It also improves the dye uptake of the fabric, making it easier to dye and giving it a more vibrant color.
- Dyeing
Here the material is dyed into another color. It is the last process of pre-treatment textile that sees the refined appearance of the fabric that has to be manufactured. Dyeing can be done with natural or synthetic dyes, depending on the desired outcome. When you paint a fabric, you are coating the surface of it but when you dye, you are changing the crystal structure of it. The clothes dyed into colors last through many wears and washings.
Textile Material Pretreating Process with Sodium Gluconate
Natural textile fiber material, in particular cellulosic fiber material (especially cotton, but also wool and silk) can be processed to form filaments, yarns and threads which can be used to make fabrics and knitted goods.
This process usually requires a pretreatment. For example cellulose fiber material can be desized, bleached, caustifised or mercerized, in such a way that undesirables such as metals like copper and iron ions or salts and/or hydroxides, such as those of magnesium or calcium are removed. Colored and sticky substances can also be so removed. The natural color associated with cellulose can be removed by bleaching (for example with hydrogen peroxide). Caustifisation and mercerization can be carried out using alkali metal solutions, and optionally alkali metal silicates.
There is a pretreatment process especially for improving the removal of undesired substances from a cellulosic textile material comprising
- Treating the textile material with an aqueous solution comprising
- Citric acid (or an alkali metal citrate),
- An alkali metal or ammonium salt of a gluconic acid, and optionally
- A mineral acid (preferably in a minor amount).
- Further aqueous solution of:
- Citric acid (or alkali metal citrate),
- An alkali metal or ammonium salt of a gluconic acid, and
- Optionally a mineral acid (preferably in a minor amount).
Example 1
An untreated cotton fabric is padded at room temperature with a liquor containing, per liter of liquor, 2 g of a commercially available wetting agent (dispersing agent)and 20 g of a composition (hereinafter defined as Composition a) comprising
- 25% citric acid,
- 25% sodium gluconate and
- 5% hydrochloric acid (30% solution), and
- 45% water.
This composition is at a pH of 2.8.
Impregnation occurs until the weight of the fabric increases 90% by liquor take up. The fabric is allowed to stand for four hours and then is washed intensively. By this method, the textile material is demineralized and is ready, optionally after drying, for further treatment.
Example 2
In order to desize enzymatically (and stabilize the enzyme), an untreated cotton fabric is impregnated, in a pad batch process, with an aqueous liquor containing , per liter of liquor, 5 ml of a commercially available desizing agent based and 1 ml of Composition a comprising
- 25% citric acid,
- 25% sodium gluconate and
- 5% hydrochloric acid (30% solution), and
- 45% water;
The pH of which is raised to 6 by the addition of soda. The fabric is allowed to stand for 10 hours. Washing and drying are then carried out conventionally and a perfectly desized material results. Jeans fabric may be scoured in a similar manner to clean it. In this case an aqueous liquor containing per liter of liquor, 10 ml of the above mentioned desizing agent and 2 ml of the composition 2, the pH being adjusted to 5.5 with soda rather than 6. The fabric is then treated in a tumbler for 40 minutes at 60°.
Example 3
Untreated silk is enzymatically cleaned with an aqueous liquor (at goods to liquor ratio of 1:3) containing , per liter of liquor, 2 ml of a commercially available desizing agent based on protease and 1 ml of composition a (defined in Example 1) that has been brought to pH 8.5 by the addition of soda. The fabric is treated in a tumbler for 25 minutes at 60° and then rinsed and dried.
Example 4
In order to complex Fe3+ ions , an untreated fabric is treated at the boil with an aqueous liquor containing, per liter of liquor, 5 ml of a commercially available, alkali-stable, weakly foaming anionactive tenside, 2 ml of composition a (defined in Example 1) and 50 g caustic soda in solid form. The fabric is impregnated until the weight of the fabric increases 100% by liquor take up. The fabric is then treated according to a Pad-Steam process at 102° for 10 minutes. The substrate is then washed, rinsed and dried.
Example 5
An untreated cotton fabric is impregnated with an aqueous liquor containing, per liter, 5 ml of the anionically active wetting agent, Sandoclean PC liquid, 10 ml of a available organic stabilizer. Impregnation occurs until the weight of the fabric increases 100% by liquor take up according to a Pad -Steam process over 30 minutes at 102°. The fabric is then washed, rinsed and dried. The resulting fabric is perfectly bleached.
The washing step can be improved by adding, per liter of washing liquor, 5 ml of Composition a (defined in Example 1) in a washing machine, washing for 30 seconds at 60°, followed by rinsing and drying.
Example 6
An untreated cotton fabric is treated with an aqueous liquor at goods to liquor ratio of 1:15, containing 5 ml/l of the Composition b which comprises
- 15% citric acid (or alkali metal citrate)
- 15% sodium gluconate, and
- 3.2% hydrochloric acid; and
- 66.8% water;
And 2 ml of wetting agent liquid and 5 g/l of hydrosulfite bleaching agent at 60° C. This is then rinsed, once hot, once warm and once cold.
This method enables bleaching to be carried out avoiding the use of sodium hypochlorite and so is more environmentally friendly (i.e. avoids the use of chlorine).
