Fair enough. But my new Endura waterproof jacket (Gridlock)says not to use fabric conditioner. If its action improves the waterproofness of my jacket why would that be a bad thing? I suppose it may be a breathability issue, although I don't think the jacket is supposed to be particularly breathable (it has zips for that purpose!)domtyler said:From Wikipedia:
Fabric softeners work by coating the surface of the cloth fibers with a thin layer of chemicals; these chemicals have lubricant properties and are electrically conductive, thus making the fibers feel smoother and preventing buildup of static electricity. Other functions are improvements of iron glide during ironing, increased resistance to stains, and reduction of wrinkling.
Cationic softeners bind by electrostatic attraction to the negatively charged groups on the surface of the fibers and neutralizing their charge; the long aliphatic chains are then oriented towards the outside of the fiber, imparting lubricity. Vinegar works on some materials in a similar way, as the hydrogen ions bind to the anionic groups on the fibers.
The disadvantage of coating fibers by hydrophobic layer is in decreasing the water absorption properties of the fabric, which may be an issue with eg. towels and diapers. Therefore the cationic softeners are often combined with other chemicals with lower affinity to the fibers.
It would normally get washed with other washing which the wife likes to use conditioner on. I'll just have to make sure it is washed separately, I suppose.Chris James said:I think it effects the performance of the DWR, at least accoridng to Field and Trek.
'Important Note: The chemicals in household detergents interfere with the DWR (Durable Water Repellent) treatment to the outside of your waterproof - the perfumes used in particular, as well as those that combine a fabric conditioner. This is why we recommend that you use a product like Grangers, which is a pure soap without additives. '
But more to the point, why would you want to use fabric conditioner on a waterproof jacket? Make it easier to iron? Make the outside feel snuggly?
Mind you, I get eczema so don't bother with conditioner at all.
Just wear it in the rain; that should do the job!magnatom said:It would normally get washed with other washing which the wife likes to use conditioner on. I'll just have to make sure it is washed separately, I suppose.
