7. Improves the stability of "acid dye/cationic dye" mixtures when Dyeing wool/acrylic blends.

DILUTION PROCEDURE
1. Hispogal-is redily dissolved in water pre-heated to 40-50 degree c. Lower tempeatures can be used if necessary
2. To reduce processing time it is recommended that the powder be Added slowly with moderate to high agitation.
3. The product is typically supplied to end-users at 20 - 40% activity, Lower dilutions are possible.

*** The following application guidelines are based on a product diluted to 30% activity ***

A. DYEING WITH DISPERSE DYES
Hispogal extra conc.increases the dispersability of the dyebath, avoding speckling during the dyeing of piece goods and filtration during package dyeing. The product shows no affinity for the dyestuff and does not generate any appreciable foam. There is also no adverse effect on crock fastness and the equipment remains clean when the product is used.

SUGGESTED RECIPES: (BASED ON A PRODUCT DILUTED TO 30% ACTIVITY)
1. 3.0 - 5.0% (owf) / JET DYEING W/ LIQUOR RATIO OF 8:1 TO 12:1.
2. 3.0 - 5.0% (owf) / PRESSURE BECKS W/LIQUOR RATIO OF 20:1 TO 30:1
3. 4.0 - 7.0% (owf) / PACKAGE DYEING W/LIQUOR RATIO OF 8:1 TO 10:1

For jet dyeing of texturised polyester. A typical procedure would be:
1. Prepare "dye pre-dispersion" by adding 1.0-3.0% product to the water Then 0.25 -0.5% seouesterant and 1.5% acetic acid the dye powder or Paste is then slowly added with mixing until uniform.
2. Raise the dyebath temp to 60-65 degree c. Add 0.2-0.5% defoamer, 4.0-6.0% Carrier and 1.5% product. Add the "dye pre-dispersion" and adjust the Bath to ph 4.5 with acetic acid.
3. Run for 10 mins. Raise dyebath temp to 90 degree at 1 degree c/min. Pressurise the vessel and raise the temp to 130 degree at 1-2 degree c/min. Run for 45-90 mins until required shade depth is achieved. Cool slowly to 90-degree c. Check shade. Cool bath to 80 degree c. Rinse goods until clear. After wash in the usual way.

For pressure beck dyeing, the procedure is essentially the same as that outlined above except that defoamer is not required. A lubricant should be added to avoid chafe marks.

For package dyeing a typical procedure is as follows:
1. Prepare "dye pre-dispersion" by adding 1.5 - 3.0% product to the Water then 0.25 -0.5% sequesterant and 1.5% acetic acid. The dye Powder or paste is then slowly added with mixing until uniform.
2. Add 3.0% product, 0.5% wetting agent and 2.5% carrier. Run for 10 Mins at 50 degree c. Raise the temp to 60 degree cat 1 degree c/min. Add the "dye pre-dispersion" and adjust dyebath to ph 5.0 using acetic acid. Raise temp to 130-degree cat 1-degree c/min and run for 60 mins. Cool rapidly and drop as hot as possible, preferably at 90 - 93 degree c. After wash as required.

B) Dyeing with Acid Dyes
The anionic character of hispogal extra conc is used to improve dye leveling and wet fastness when using acid dyes on wool, polyamide and blended fibers. In this application the product blocks the reactive sites on the fiber and restrains the dyestuff. Addition levels vary depending on depth of shade required, dyeing equipment, dyestuff, liquor ratio and fiber type.

Typically for warp-knitted nylon fabric dyed on a beam, the dyebath is set cold at a liquor ratio of 30:1, the product is added at 2.0 - 3.0% for pale dyeings or 0.1 - 1.0% for deep dyeings with 1.0% acetic acid. The fabric is run blank for 20 mins at 40 degree cand then 3.0% ammonium acetate. 0.5% seouesterant, 0.2% defoamer, 2.0%amphoteric retarding agent and the "pre-dissolved dye" is added.

The dyebath temp is then raised gradually at 1-degree c/min and dyeing continued for a maximum of 60 mins at the maximum dyeing temp (usually at the boil). The shade is checked and the fabric is cooled and rinsed, after treated if necessary, softened, hydroextracted and stenter dried.

C) Dyeing with Cationic Dyes
Hispoga Extra conc.is used as a complexing agent with cationic dyes to retard the rate of dyeing at addition levels of between 0.5-4.0%. Higher addition levels enables the product to act as an efficient dispersantin the removal of excess cationic dyes from acrylic fabrics and yarns

A typical procedure would be to add the product at 3.0% to the dyebath and adjust to ph 4.0-4.5 with acetic acid. Raise the temp of the bath to the boil over 30 mins and continue to boil for 60 mins. The yarn is then rinsed and re-dyed.

Note well that optimum addition levels are dependant on the choice of dyestuff, liquor ratios, dyeing equipment and fiber type.
