Shrinkage - What is it?
« on: February 11, 2013, 01:55:48 PM »
Yarns and/or fabrics are not fixed materials.  They consist of separate fibres that will stretch when exposed to tension, i.e. they elongate during the process of being made into cloth (during spinning, weaving, bleaching, dyeing and the various finishing processes, yarns and cloth are under continuous tension).  Some or all of this stretch within the fabric is retained in the post-loom fabric because of friction between the fibres and the yarns.

The stretch that occurs can be eliminated when the friction within the fabric is reduced.  This will happen during  soaking and/or washing, where both water and soap act as lubricants.  The lubricants, along with the mechanical action of the washer, help the fibres relax and contract (shrink) back to their original length.

One of the reasons that dry cleaning does not shrink natural fabrics is that the friction within the fabric is not reduced by dampening.

We get a lot of question of the type:

How much will the thigh shrink?
How much will the front rise shrink?

All vertical measurements will shrink at the same ratio as the inseam shrinkage
All horizontal measurements will shrink at the same ratio as the waist shrinkage

So say the shrinkage of the inseam in 2" over 36", that is 5.55% shrinkage

Hi Guys,
im going to resurrect this topic, or put it to sleep. i work for an industrial laundry machine supplier and some of our machines produce 120kg of washed linen every 2 minutes. we spend huge amounts of money proving to large hotel chains that its not our fault their sheets or towels have shrunk. we regularly ship sample packages to our lab in the Netherlands to be test. and then people dont like being told that the 1 million euro worth of sheets they just bought will shrink unevenly or by huge amounts. we sometimes get garments to test and my friend there states in his opinion some denim is the worst for quality and for ripping people off, for example one manufacturer in particular beginning with D the denim is bought extremly cheaply and the cost of one pair to produce can be under 3 euro, they then sell for up to 250 euro!! the shrinkage in these is abnormal.
all items shrink at different rates even from the same roll of material. what im getting to is ....IHUK i think do an awesome job of informing on size and shrinkage, and the jeans are top quality  :)
