    That's very dependent on the post manufacturing processes (eg: dying and washing, temp, etc) usually that is found on your specification sheet, or in consultation with your manufacturer. The values can vary between fabric types, construction, pattern piece orientation > grain-line etc. There isn't a hard and fast general rule - experience is perhaps your best way to look at shrinkage factors, find someone whom has that technical knowledge or read it off the spec test sheet that accompanies a sample documentation. And certainly don't 'wing' it with a guesstimate - that can be a recipe for batch disaster.

    Hi Ottoline, 

    Thank you for your reply. Having the manufacturer to do the calculation is a great idea. :)

    Perhaps I can rephrase my question. In Gerber, I can change the pattern piece's X-axis and the Y-axis in the model editor.
    However, I am wondering if CLO3D has a similar function that I can use if I have the fabric shrinkage test report.

    Or as you suggested, even though there is a way to make the change in CLO 3D, it is better to test the patterns at the manufacturer's end?

    Much appreciated.

    Hana, I believe you can accomplish this in CLO by using Shrinkage. Check the link below:

    When you do the garment shrinkage factors you may also need to do the full garment assembly value (measure) at key areas, that you compare to your makers batch process (before and after on the assembled garment). Because in isolation a factor for shrinkage on a small swatch sample may turn out to be different to the assembled dyed and washed garment dependent on styling factors which is where fit is critical.

     

    So just bear in mind that you can check this before and after for critical girths to tweak the shrinkage factor you may place in as a general pattern piece value for the fabric that a manufacturer might recommend. That's maybe the difference between the theory of what a spec sheet says and what actually happens. So checking these accumulated lengths is always a good post sample check. Often a garment style may behave at different accumulative shrinkage ratios (outside tolerance spec) even though they share the same fabric, so that is an easy way to take a quick digital measure to compare with the actual garment assembled girth.

    Thank you. This method is brilliant.
