Textile Softener IOTA 270 
Product Description

IOTA 270 textile softener is a novel (AB)n linear, polydimethylsiloxaneamino polyalkyleneoxide polyether block copolymer. IOTA 270 textile softener is designed to provide soft, silky, full hand to fabrics treated with fluorocarbon soil release additives, while incurring little or no interference with the soil release properties. The softening properties that are provided by IOTA 270 textile softener are durable for numerous detergent washes.

The use of IOTA 270 textile softener imparts superior softness and very low yellowing compared to conventional amino silicones when applied to a wide variety of fabrics, including 100% cotton knits and wovens, synthetics and cotton/synthetic blends. In addition, fabrics treated with IOTA 270 textile softener are not hydrophobic. IOTA 270 textile softener imparts a slow wetting durable hydrophilic character to fabrics. 

Key Features and Typical Benefits

• Provides the high level of softness for all types of fabrics.

• Does not interfere with soil release properties of fabrics treated with fluorocarbon soil release agents.

• Does not cause fabric yellowing.

• Suitable for all normal application methods, such as pad bath, exhaustion and spray

• Can be diluted with water or alcohol.

• Water dilution’s of IOTA 270 textile softener have good compatibility with finishing baths.

• Formulations containing up to 23% IOTA 270 textile softener actives (33% as received IOTA 270 textile softener) are only combustible and at 7.5% actives no flammability warning label would be required.

Potential Applications

IOTA 270 textile softener is intended to be used in textile finishing as a premium softener for all types of fabrics such as cotton, synthetics and cotton/synthetic blends, especially those which are also treated with fluorocarbon soil release agents. IOTA 270 textile softener is a very effective softener for use in wrinkle free garments that are treated with DP resin and fluorocarbon soil release. Dispersions of IOTA 270 textile softener have good shear stability. Therefore it can be an good softener for applications where normal, emulsified softeners do not show adequate shear stability such as in EVAC systems.

IOTA 270 textile softener is normally applied as a water dilution, which is blended into the treatment bath formulation to provide the desired silicone add-on.

Performance

Performance Soil Release and Softness.

The data presented below demonstrate the superior soil release and softness provided by IOTA 270 textile softener to fluorocarbon and DP resin treated 100% cotton twill. Performance was compared to that of:

(a) L-45* (1000), a conventional silicone

(b) IOTA Plus, a high performance aminosilicone softener

(c) IOTA Softener, a hydrophilic silicone-amino-polyalkeleneoxyde terpolymer

(d) 80/20 blend of IOTA Softener and IOTA Plus

Soil Release Rating, Softness and Silicone Durability on 100% Cotton Twill Fabric Treated with 1.0% FC-248, 1.0% Silicone, BOWF

Data above indicates that IOTA 270 textile softener provides superior softness along with almost no loss in soil release properties. IOTA 270 textile softener provides durable softness to the fabric, since fabric treated with it retained most of the initial softness even after five washings.

Product Safety, Handling and Storage

Store in original container protected from direct sunlight in a dry, cool and well-ventilated area, away from incompatible materials and food and drink. Store locked up. Eliminate all ignition sources. Separate from oxidizing materials. Keep container tightly closed and sealed until ready for use. Containers that have been opened must be carefully resealed and kept upright to prevent leakage. Do not store in unlabeled containers. Use appropriate containment to avoid environmental contamination.
