Upholstery shrinkage test
« on: September 10, 2009, 10:31:56 pm »
What is the best way to do this test?

Is it the 4 pin measuring method, or would most of you, depending on what fabric you are cleaning, just keep water temperature to around 40 degrees?

The 4 pin test.
The temp of the water has nothing to do with shrinkage, if an item is going to shrink it will do even with cold water.

Ok mark thanks for your reply.The reason i mentioned the water temperature is because when i went on the NCCA course they never mentioned anything about the 4 pin test,ive just picked that up from you experienced cc.On the course they advised us to do a burn test on the inside cushion,colour test,then hwe with temperature at a lower heat to stop any possible shrinkage.

As you can tell im new to cc,and just trying to find out the most practical procedures.Cheers.

Please explain the 4-pin test if you would.

Offer up a business card to an unobtrusive area of the sofa - put a pin through the fabric at each corner of the card - remove the card and spray the area between the pins, let it dry - then offer up the card again and see if it overlaps the pins.

If it does - shrinkage

Thanks, so if there's shrinkage then its best to not use HWE? or can you get away with it depending on the level of shrinkage.

Personally, if there's shrinkage I would walk or use dry mineral solvent if I thought I would get a result with it.

To be honest I have yet to come across one that would shrink - although I am sure some of the other guys have.

Only shrinkage I ever experienced on fabric was on cotton print about 20 years ago.

In 15 years have never experienced it and after 2 months never tested for it. There were some top end suites about which were a sandwich of two fabrics and I think a few people had problems with those.

What I've come across occasionally has been the aftermath of customer cleaning sofa covers in the washing machine and drying them BEFORE putting the inset back in...............does'nt work.
