Cordura Nylon

gogojojo | Posted in General Sewing Info on

Hi,

Has anyone ever sewn with cordura nylon 1000 denier?  It’s heavyweight backpack material.  No matter what I do, I can’t get the bobbin thread to look decent, especially when I’m sewing velcro onto it.  I’ve tried every machine in my arsenal, including a commercial walking foot, with various tension adjustments on both lower and upper threads.  The best looking stitch, believe it or not, comes off of my 1920’s singer.  The best way to describe the look of the bobbin stitch is wavy.  The top stitches are always perfect, but the bottom looks crowded.  I’m using a big needle; tried 16, 18 and on the commercial machine, 20.  The thread is nylon upholstery thread.  What am i doing wrong? 

Thanks in advance,

Jo

    Best bet is to contact the manufacturer --  it does require special needles and attention to machine tension.  It's an industrial product and therefore mostly sewn on industrial machines.

    But I'm certain if you supply them with your type of machine, etc., they'll be only too happy to be of assistance

      Hi Jewel,

      I know you said you tried lots of tension combinations.... I have sewn with this sort of fabric, and run into the same problem...  based on what you said, I would tighten the bobbin tension a touch each time until it catches enough to take the wave out.  Usually when mine was doing that, I could see the top thread too loose also....from the bottom side, so tighten that slightly too.  Try it on scrap until you get it just right, because it can be so touchy- and don't do top and bobbin tension adjustments at the same time..... the heavy nylon thread offers some of the problem...... You might try backing your velcro with interfacing, especially if the back side  is going to be hidden from view on your finished item.  It is mostly trial and error..... as you have well found out, but small adjustments, then sewing a sample will help a great deal.  I have 5 machines I sew with too, and have found some just handle the heavier fabrics better.  Hope this helps.
