hi all,
iv just been to look at a job today because the lady wasnt happy with her last cc as it seems he damaged the carpet, it appears to have sort of bubbled in places and rucked up a bit, any1 have any idea what caused this so i dont make it worse,

the carpet apears to have a man made backing and seems well fitted

[John_Flynn]

Instead of shrinking believe it or not this carpet has stretched, if the previous cleaner did this do you intend to rectify it?? Remember that as soon as you start to work on this ladies carpet the problem becomes yours !!.

Personally I would leave well alone unless you like buying problems.

[dave401uk]

Sounds to me as if it has been stretched,and more than likely cleaned at to higher tempreture.

As abouve unless you enjoy problems, leave well alone

I agree, synthetic carpet with too much heat has stretched it.  Advise her to have a carpet fitter do his best to rectify it before you touch it, this will make you look half inteligent in front of the custy.

Can I ask what training you have had? manufacturer or association?

Chris

[conallon]

as above, or make it clear you can clean it but not correct the streching,or advise her to seak the advice of a carpet fitter ie re-stretch then when sorted you will clean it

Conrad

p.s. chris beat me to it

[Dave_Lee]

May also be badly delaminated, restretching it will make it worse as will firther cleaning. It may not be the fault of the last CC, some carpets have insufficietly bonbded secondary backing and this problem is always going to arise at some stage.

hi all,
thanks for all your help and answers
first of i dont intend to rectify it and thats not expected all thats wanted is a new carpet cleaner as the lady no longer wants the old one back because of this problem,
i just wanted to know the cause of the problem so as i didnt make it worse and as chris mentions to look more intelegent to the custy as she was asking me wat had caused the problem i had suggested orriginaly it may have been delamenation as posted by dave but on inspection the carpet dosent  seem to have a secondary backing,
as you have all mentioned that it is most likely caused by being cleaned at to hi heat could someone let me know wat heat you would suggest cleaning at please,

and chris,
my training only consists of manufacturer (extracta) at the minute and allthough i plan on doing further training i think iv learnt more of you guys so once again thank u

Hi Red

I've also seen this problem when someone has overwet the carpet.

However it may well be a manufacturing fault.

Dimensional stability is a big issue with all continous process material manufacturing ,  as among other things too much tension can induce too much stress in the machine direction and this can be 'released at a later date.

Too higher temp can undoubtedly lead to expansion as the stresses are released .

D'ont be too worried because this sort of thing is quite rare or non existent once  you become experienced.

Cheers,

Doug

thanks doug
is it  possible to clean carpets to much
as this person has been getting them done every six weeks
could this have contributed to the problem

[Chris Bailey]

Less is more, if your cleaninig carpets every 6 weeks then all that should be required is as little water as possible.  Ideally an alternative method to HWE, perhaps one of the many bonnet systems that are about!

Prochem and the NCCA training courses are excellent.  The reason I ask is that although people on this forum are able to offer a wealth of knowledge and experience, I should know cus I have learnt a lot from this lot as well, good training will give a foundation of knowledge for you to build on giving you confidence in front of your custy.

Red,

Cleaning every 6 weeks will cause problems with any carpet likely to stretch.

Afterall if it stretches 5 mm each clean then thats about 45 mm in a year!

Bonnetting is going to produce more resistance than HWE and may well result in more stretching if carried out every 6 weeks.

Seems a best to advise the customer to have the carpet refitted prior to cleaning and then clean carefully with lowish temperatures and water consumption.

It is perfectly possible to clean with HWE using a low water approach.Prespray well and then mist above carpet and extract.

This is the method I use for BW's

Cheers,

Doug

Well Red, your customer has a tufted carpet that has delaminated, it can be tightened, cleaned, washed, boiled, scrubbed, and fryed, and it will only get worse until it is lifted and the back coated with an appropriate adhesive, if nothing is done, it will split and fall apart. We get it all the while with Tientsin Chinese rugs.

thanks for all your help,
but im starting to get confused now has it streched or delaminated?
i was under the impression it can only delaminate if it has a secondary backing and this dosent seem to be the case, the backing is woven and has nylon in it

[Barry Pearce]

Red, your basic tufted carpet is like a sandwich, 3 layers, Pile, Skrim, and a Backing skrim. The pile is punched or tufted through the skrim just like commision knitting, its so light 2 men could lift a full 4M roll, in another factory it is laid face down, streched under tention and adhesive is applied to the back, into this wet adhesive is pressed and rolled the backing skrim and dried, that is a simple insight to a highly technical finished product,
Delamination is the breakdown of the adhesive between the 2 skrims, the backing skrim normaly retains some adhesive, so stays stiff, but with the pull and push of the pile through its skrim, it starts to stretch, and will continue to stretch untill it rips.

someone may have used white spirit or the like, to remove something...and poured it on...this happened to me once...just stuck my nose in it, and that told me.
