» CATASYST – RRD (Scouring, Levelling, Emulsifying, Machine Cleaning & Lubricating Agent) |
|
 |
|
CATASYST-RRD is a specially formulated “all in one auxiliary” for dyeing of polyester & polyester blended fabrics. It is stable under High Temperature High Pressure conditions. Therefore it is highly suitable in all machines such as Jet Dyeing Machine, Beam Dyeing Machine, Closed Jigger, Winch & Yarn Dyeing Equipments. It acts in many ways for scouring, emulsifying & cleaning as well as lubricating when used in processing of fabric.
CATASYST-RRD is applicable to fully flooded, semi-flooded & low liquor systems. It is low foaming & is stable in high performance pump flow systems. CATASYST-RRD requires no other addition to dyeing system apart from a pH control buffer. |

|
|
|
|
|
APPLICATION : |
|
|
|
|
|
First clean the jet dyeing machine as follows :
» 0.5 to 1gm./lit. CATASYST RRD
» 2gm./lit. Caustic Soda Flakes.
» 2gm./lit. Sodium Hydro Sulphite.
Run the machine in the above solution at 130 C for 60min. followed by cooling, draining & finally give Acetic Acid rinse to ensure the removal of Oligomers etc.
Now1. Take the required quantity of water, add o.5 to 1.0gm/lit. CATASYST-RRD or 0.1 to 0.2% o.w.f.
2. Add Acetic Acid to make pH between 5 to 6.
3. Add pre-dissolved dye stuff & start the program.
CATASYST-RRD will help in eliminating the problems, such as barrines, foaming entanglement, patchy or uneven dyeing in Jet Dyeing Machine, Beam Dyeing, Yarn Dyeing machines, Jigger & winches of H.T.H.P. process. |

» POLYPRINT – HTP (Accelerating Agent) |
|
|
|
POLYPRINT-HTP is an excellent accelerator (printing aid) for developing disperse dye prints on polyester by loop steaming / thermofixing. |
|
|
|
|
|
GENERAL CHARACTERISTICS : |
|
|
|
|
|
» APPEARANCE: Colourless to pale yellow transparent liquid.
» IONIC NATURE: Nonionic.
» pH: 6 – 9.
» SOLUBILITY: Readily soluble in water in all proportions. |
|
|
|
|
|
SALIENT FEATURES : |
|
|
|
|
|
POLYPRINT-HTP :
» Acts as hydrotropic agent, dissolving the colour in itself & then getting dissolved in aqueous base. This reduces the particle size of the disperse colour, making it easier to penetrate.
» Forms the near most layer to the polyester because of its affinity to the same. Disperse colour dissolves in this layer and transfers to the polyester, giving full colour value.
» Fixes more amount of dye, leaving very less unfixed dye, to be washed off in subsequent process. This reduces the bleeding of the dye during washing, offer-ing higher probability to obtain tint free, brighter prints. |
|
|
|
|
|
APPLICATION : |
|
|
|
|
|
Make the gum paste as usual. Add citric acid or any suitable acid to adjust the pH 5 to 5.5. Add 1Kg of POLYPRINT-HTP per 100Kgs. of gum paste. Add predisolved POLYPRINT-HTP with the gum paste in adequate quantity of water & mix well to obtain desirable depth and tone of the shade. Print, dry, thermofix, or loop-age as usual. Wash, dry & finish as usual. |

|
PHYSICAL APPEARANCE : |
|
|
|
|
|
» Pale yellow transparent liquid.

» POLYCOL – DFA (Dye Fixing Agent) |
|
|
|
POLYCOL-DFA is a versatile dye fixing agent used in after treatment of direct and reactive dyed fabric to improve their wash fastness properties. This results due to the formation of electrostatic bonds between the dye anions and cations of dye fixing agent which will result in good fixation of the dye. |

|
|
|
|
|

|
|
|
|
|
For medium to dark shades: Ratio : 1.5 to 3% (o.w.m.) by exhaustion at 50°C.
