I cleaned a synthemtic carpet today, all edges seemed well gripped, a few minuetes after cleaning it starts to bobble in places but the carpet hasn't come away from the edges. I was using a CFR at 300psi, after using the blower on it it seemed to start to flatten out. Because the edges of the carpet didn't come away from the wall at all im wondering if it was still shrinkage or maybe stretching??
Sorry the pic wont load
-
stretching, will be fine tomorrow, go have a beer.
-
Sweet, I presume it's because I got the backing wet?? but why did it strech and not shrink??
-
not a clue, ive had a few wavey ones, every one has settled back down, no one knows why but my guess is nylon content in the backing.
-
Its just caused by swelling of the fibres which over a full room can be quite marked. As they dry the flatten out. If you imagine every foot of carpet swells by 1mm, over the whole room that can look frightening.
Its the same with timber floors in a flood. Even if they have only had a 5% moisture increase they can look like the Himalayas, unfortunately or fortunately if you are being paid to rip it up, they don't go back flat.
-
Right, so i didnt neccessarily get the backing wet, just wetting the fibres can do this?? As long as they flatten out thats good :P
-
Come accross a few a year like this and as the above posts say dont wory it will relax again :)

A carpet made entirely of synthetic fibres will be prone to stretching either from temperature or agitation.
Usually they will go flat after a few days but some may need refitting.
-
Same as everyone else, I've seen it a few times and it's always gone back the next day.
Very scary for a newbie though, I remember flapping all night about it hoping it would sort itself out.
tend to see the signs pretty soon now and just pre warn the customer
-
Ok, so when you say made entirely of synthetic fibres, do you mean the backing aswell?
-
Had this many times at the same customers house. 1st time it happened was quite scarey but ow i know every time it will flatten back after 24 - 48 hrs.

Yes Adam backing fibres as well.
A pre cleaning inspection and burn test will identify this prior to cleaning.

Reckon it's happened to us all, one was a flat domestic carpet, went back ok, the other was in a common lobby area of a home, both looked diabolical and was cleaned lukewarm, dried out flat so
don't lose any sleep ;D
-
Also to do with latex swelling in backing.
