uctures of typical non-ionic softeners.
3.4.6 Silicone softeners
3.6 Chemical structures of typical silicone softeners.
3.5 Schematic comparison of important properties of softeners
– include wall coverings, carpeting and most industrial textiles.
3.4 Product types and their chemistry
3.4.1 Cationic softeners
3.2 Chemical structures of typical cationic softeners.
3.6 Compatibility and combinability
Softener finishes are often combined with easy care and antistatic treatments. In combination with fluorocarbons, most softeners reduce oil repellency. Some ionic, surface active and silicone free softeners are not compatible with water repellents. Since softeners are usually also excellent fibre lubricants, softening finishes often give poor anti-pilling and slippage properties.
3.4.2 Anionic softeners
3.4.3 Amphoteric softeners
3.4.4 Non-ionic softeners based on paraffin and polyethylene 3.4.5 Ethoxylated non-ionic softeners

3.7 Evaluation and testing methods
The most comprehensive but most expensive method of objective hand evaluationwas developed by Kawabata and co-workers21–23 and is called KES-F (Kawabata Evaluation System-Fabrics). KES• • • • • tensile and shear properties (KES-F1) bending properties (KES-F2) compressibility (KES-F3) surface properties(KES-F4) thermal properties (KES-F7)
3.3 Typical softened textiles articles
• Almost all apparel and home furnishing textiles are treated with softeners; • Only a few speciality fabrics do not receive a softener finish;
FAST (Fabric Assurance by Simple Testing) is another well known system.

3.8 Particulars of and troubleshooting for softening finishes
• Overcome the embrittled property • the feeling of added fullness • antistatic properties • sewability.
Disadvantages
• Reduced crockfastness • yellowing of white goods • changes in hue of dyed goods • changes in fabric structure slippage

The hand of a fabric is a subjective sensation felt by the skin when a textile fabric is touched with the finger tips and gently compressed.
