» POLYCOL – SRD (Levelling Agent for Acrylic Dyeing)

	POLYCOL-SRD is a cationic retarder cum leveling agent useful in dyeing of acrylic fibre / yarn. It has good retarding action with leveling properties. It has no effect on fastness properties of dyeing.

	PHYSICAL PROPERTIES :

	» APPEARANCE: Pale clear liquid. » SOLUBILITY: Soluble in water. » IONIC NATURE: Cationic. » COMPOSITION: Blend of organic surfactants.

	APPLICATION :

	POLYCOL-SRD is normally added to the bath prior to the dyestuff. Generally 0.5 – 3% POLYCOL-SRD is recommended depending on the depth of shade.

	COMPOSITION OF THE DYE BATH :

	» X%: POLYCOL-SRD » Y%: Dyestuff » 2-4%: Acetic Acid (60%) » 1-2%: Sodium Acetate » 5-15%: Glaubers salt

	DYEING METHOD :

	The fibre / fabric is first treated briefly in this bath. The dyestuff dissolved in an equal quantity of 60% Acetic Acid and the required quantity of hot water is added to the bath. The temperature is then increased to 80 – 85oC in about 15min. and raised slowly to the boil in 40 – 45min. The dyeing is continued at this temperature for 60 – 90min. Then give hot wash and cold wash.

	PACKING: 50Kgs. plastic containers.

» POLYTEK – UBC (Universal Bath Conditioner)

	ATTRIBUTES :

	» Very useful in the hardest water for good whiteness in bleaching, uniform dye-ing and better brightness with optimal colour yield. » High powered deactivator for heavy metal ions apart from Ca++, Mg++ and other impurities. » Is non-foaming and avoids salt deposition on substrate and machines. » Avoids scaling up on the machines. » Effective over wide range of pH and temperature conditions (up to 1400C) and suitable for all types of substrate and blends. » Does not chelate metal ions of dyes. » Prevents catalytic damage by heavy metal ions in the bleach and mercerising liquor. » Prevents precipitation of hydroxides and earth alkali silicates. » Improves overall fastness properties of dyed substrate, when used in dyeing and washing off stages.

	GENERAL CHARACTERISTICS :

	» APPEARANCE: Pale yellow clear liquid. » IONIC NATURE: Anionic. » CONSTITUTION: Organo modified salts.

	APPLICATION : 0.1 to 1.0g/l of POLYTEK-UBC to be used in all stages of process-ing depending upon the needs.

» POLYCOL – DDA (All purpose disperse dyeing assistant)

	HIGHLIGHTS :

	» Is a good pH regulator throughout disperse dyeing cycle. » Provides dispersing and leveling characteristic in disperse dye bath i.e. no of additions for additions of leveling agent in most of the dyeing. » Free from mineral acids, therefore safe on blends (especially with viscose). » Suitable even in hard water, thus retaining brilliancy & tone of the shade i.e. no need of additional sequesterants. » Is low foam & eco-friendly also.

	GENERAL CHARACTERISTICS :

	» APPEARANCE: Light brownish clear liquid. » IONIC NATURE: Anionic. » CONSTITUTION: Blends of surfactants, organic acids and salts.

	APPLICATION :

	0.7 to 1.5g/l of POLYCOL DDA in dye bath. Always first add POLYCOL DDA to dye bath, then dose in leveling agents, dyestuffs etc.

	STORAGE: Stable under normal conditions.

» POLYCOL – MCLI (Reduction Clearing Agent / Anti Tinting Agent)

	POLYCOL-MCLI is low foaming detergent with reducing action which replaces sodium hydrosulphite and usual detergent in reduction clearing of disperse dyeings and prints. It is also as a washing off agent for Polyester / Cellulose blends.

	GENERAL CHARACTERISTICS :

	» APPEARANCE: Amber, opalescent liquid. » IONIC NATURE: Cryptoionic. » CHEMICAL CHARACTER: Alkyl polyglycol ether & organic reducing agent.

	APPLICATION :

	Reduction clearing of disperse dyeing. On jet, Winch, Jigger, Beam or Package dyeing machine. 1 – 4g/l Polycol-MCLI 1 – 2g/l Caustic Soda Flakes. at 70°C 80°C for 15 – 20 minutes. Hot wash, rinse cold & neutralise with dilute acetic acid. In the case of dyeing where exhausion is almost complete i.e. no residual dyestuff in the bath, reduction clearing can be carried out in the same bath by addition of POLYCOL-MCLI and caustic soda flakes. Reduction clearing of disperse prints. On a continuous washing machine. 1st bath1g/l POLYCOL-MCLI 2 – 4g/l Hydrosulphite (to enhance reducing action at low temperatures) 2nd bath2 – 3g/l Caustic Soda Flakes at 25°C 30°C 2 – 6g/l POLYCOL-MCLI 3rd bath1 – 3g/l Caustic Soda Flakes at 70°C 80°C Rinsing baths– Rinse with decreasing temperatures from 80°C to cold. Final baths– Neutralise cold with Acetic Acid. Reinfrocing every 20min. add approx. 1/3 amount of POLYCOL-MCLI and 1/6 amount of caustic soda. Machine Cleaning 3 – 4g/l POLYCOL-MCLI liquid. 2 – 4g/l POLYCOL PDM 2 – 3 Caustic Soda Flakes at 80°C 90°C for 20-30 minutes. Drain and rinse well.

	PACKING: 50Kgs. net in HDPE Containers.

» POLYCOL – PDM (Unique Multifunctional Disperse Dyeing Assistant)

	ATTRIBUTES :

	» Enhances migration of disperse dyes for achieving level dyeing is one of its prime functions. » It effectively scours polyester along with the dyeing program thus saving on time, energy, water and effluent load. » Low foam profile gives trouble free fabric movement in high turbulent low liquor ratio machines. » Reduces the problem of barriness, and helps to achieve solidity of shades in differential yarn / fibre mix in polyester fabric. » Good machine cleansing action. » Excellent for correction / re-dyeing (leveling) of odd-lots to achieve uniform (ontone) effect. » Better yield of dyeing as it has no retardation effect on disperse dye exhaustion (Like conventional leveling agents) even at higher dosage levels.

	GENERAL CHARACTERISTICS :

	» APPEARANCE: Pale yellow to amber coloured liquid. » IONIC NATURE: Non-ionic. » CHEMICAL NATURE: Blend of Solvents & ethoxylated esters.

	APPLICATION :

	» 0.5 – 2gpl. POLYCOL-PDM at pH 4.5 5.5 in routine dyeing. » 3 – 5gpl. POLYCOL-PDM with 1gpl acetic acid (Glacial) for correction of Patchy / uneven dyeing at 1300C, 30min. » 1 – 3gpl. POLYCOL-PDM with 2gpl Caustic Soda Flakes + 2gpl. Sodium Hydro-sulphite for machine cleansing at 90 1300C, 60min. Final rinsing with POLYTEK-UBC 1gpl helps to remove scales if any.
