FABRIC SOFTENERS- SHORT HISTORY

First used in the 20ies in the textile industry in order to compensate negative effects of dyeing Typically: water, soap and olive or corn oil

Since the 60ies, successfully offered on end-consumer market


FABRIC SOFTENERS- SHORT HISTORY

Typically: quaternary ammonium salt with one or two long alkyl-chain

Effects of these esterquats more and more completed with other effects

TYPICALLY EXPECTED FABRIC CARE EFFECTS

Softer feel Good rewetting Easy ironing Fewer wrinkles Easy drying Water repellency Fragrance substantivity Fiber careWacker Silicones for Fabric Care Dr. Richard Becker, J. Kugler, A. Maier, Dr. Elisabeth Gonthier, S-P-I, Household Care, May 2009, Page 6

HOW CAN FABRIC CARE EFFECTS BE INTRODUCED?

Applied through wash cycle

FABRIC-CARE COMPONENTS

Applied through rinse cycle


APPLIED THROUGH WASH CYCLE

Competition: desorption of soil vs. adsorption of fabric care component

Currently, no satisfying solution has been found

Holy grail of detergents industry: so-called 2-in-1 detergents


APPLIED THROUGH RINSE CYCLE

after wash cycle is over

together with rinse-cycle softener during the last rinse stage

well-established process for organic based, fabric-care components

WACKER FC 207 micro-emulsion of an amino-modified silicone fluid

can be easily formulated into standard fabric softeners

improves the softening efficacy of fabric softeners and the fabrics get a significant softer and pleasant touch

Additionally reduces the friction forces of the iron and therefore ironing properties are improved significantly.

Many consumers do not use rinse cycle softener due to this hydrophobicity e.g. on terry towelsWacker Silicones for Fabric Care Dr. Richard Becker, J. Kugler, A. Maier, Dr. Elisabeth Gonthier, S-P-I, Household Care, May 2009, Page 17

TECHNOLOGY FOR WRINKLE REDUCTION

Introduction of substantive crosslinkable aminosilicones onto the fabric Crosslinking occurs at an elevated temperature during ironing Fabric is protected against creases Deposited aminosilicone must disappear during next washes


WACKER FC 201 polysiloxane emulsion Self-crosslinking, one-component silicone finish Imparts flexible, shape-stabilizing characteristic to textile fabrics

TEST FOR WRINKLE REDUCTION DIN 53895


DIN 53895 SELF-SMOOTHING BEHAVIOUR OF TEXTILE FABRICS AFTER LAUNDERING AND DRYING

Procedure: The fabrics are Washed, Rinsed and treated with softener / silicone, Air dried. Illuminated with a standardized shine box. The test fabrics are compared with standard wrinkle replicas (AATCC No. 124-2005).


DIN 53895 SELF-SMOOTHING BEHAVIOUR OF TEXTILE FABRICS AFTER LAUNDERING AND DRYING

Self-smoothing describes the wrinkles after washing, rinsing / treating and air drying.

FASTER DRYING = COST SAVING

Drying of clothes in tumble dryer: less water => less evaporation heat => less energy cost Germany: Average energy costs per drying cycle: 0.65 Euro1 => average German consumer spends 500 Euro for drying in 10 years1

According to Der Spiegel (Heft 6, 2006), average consumer cost per kwh in Germany is 0.185 Euro/kg. Drying cycle consumes 3 - 4 kwh.

Air dried clothes need less time for drying
