PVA dispersion

Introduction :
Americos KS-3983 is a polyvinyl alcohol dispersion used for imparting durable finishes with a firm handle on textile fabrics of all kinds.

Features :

• Imparts stiffness and body to the fabric
• Imparts dimensional properties
• Imparts durable drape and shape to the fabric

Properties :

Appearance	Translucent
pH	Mild acidic
Solubility	Readily miscible with cold and hot water
Ionicity	Nonionic
Stability	Stable in hard water and mild acids and alkalis

Application :

Type of Textile	Concentration of Americos KS-3983 (gpl)
Voiles, dhotis, mulls, etc.	20 - 25
Shirting and poplins	20 - 35
Buckram	400 - 600

Americos KS-3983 can also be used in various other types of fabrics and finishes along with softeners and anti-creasing agents.

Americos KS-3983 is available in two different concentrates, 7% dispersion and 15% dispersion. Americos KS-3983 7% dispersion is a ready to use formulation where as Americos KS-3983 15% has to be diluted as per the required finish.

Packing: 50 kg, 125 kg and 200 kg HDPE drums and carboys

Impregnate the fabric for 70 - 80% pick-up and dry it at 120 - 140°C for 2-3 min.

Introduction:
Ameristol ISN is a permanent elastic finishing agent with super handle. It can be combined with easy-care and similar finishes. Prior tests are recommended in all cases to determine the influence of any combination on the final effects.

Properties:

Appearance	White, low viscosity emulsion
Ionic Charge	Non ionic
pH-Value	6 ± 1
Solubility	Easily diluted with cold water. Dilution water must be slightly acidic.
Acid Stability	Stable to normal mill dilutions
Alkali Stability	Not stable to presence of alkali
Water Hardness	Stable to water of 50° German hardness.

Compatibility:

• Ameristol ISN has soft flowing handle with "springy" character
• It is temperature stable and improves sewability performance
• It is suitable for thermo sol process
• It is durable for dry-cleaning

Usage:
Ameristol ISN gives increased elasticity and a soft smooth handle to all fiber types and their mixtures.

Pad bath:

Ameristol ISN	5 - 20 g/l
Wet pick-up	80 - 100 %
Dry	150° C

Easy-care finishes:
Ameristol ISN may be combined with normal easy-care resins to give durable softening effects together with a positive effect on abrasion resistance, Elmendorf values and crease recovery.

Typical pad bath recipe:

Americos Wrinkle Free ARN	30-60 g/l
Ameristol ISN	5 - 20 g/l
Acetic acid (60 %)	2 g/l
Magnesium chloride	10- 20 g/l
Wet pick-up	70- 80 %
Drying	130°C
Curing	4 min at 150°C

Comment:
To avoid problems with alkaline liquors, dilutions should be made with the prior addition of 1-3 g/l Acetic acid. Strong mechanical forces may have an adverse effect on liquors containing silicone products such as Ameristol ISN. Therefore the use of high pressure pumps and high shear mixers should be avoided.

Storage & Handling Precautions:

• Store in a cool place
• Avoid storing in direct sunlight
• The shelf life of Ameristol ISN is six month if stored below 40°C
• The usual precautions in keeping chemicals away from eyes and skin should be observed
