SEWING MACHINE PROBLEMS?

Question

I tried a sewing test on a piece of velour. No problem. When I test on microsuede I have gaps in the stitching both front and back. Really big gaps. Any thoughts. I tried adjusting tension. Still no problem with velour but microsuede same results. Help

Answer 1

Microtex needle, lengthen stitches over those you'd use in an equivalent weight of cotton woven, play with the upper tension.  You may find it sews better with a slight zigzag (width 0.5-1mm) compared to straight stitch.  Consider trying tissue paper above and/or below the stitching.

Generally, with most microfiber fabrics, I use a thinner thread than I would otherwise (polyester "bobbin thread" or really good quality serger thread) as it helps prevent threadjamming and puckering.

Answer 2

Sewing With Microfibers

In general microfiber fabrics are easy to work with; however, the seams may "pucker" a little in sewing.  Avoid puckering by:

1.  Use a new sharp needle; preferably a fine Microtex or microfiber needle;

2.  Use a good quality 100% polyester thread (if you use a cotton or cotton-wrapped thread, it may not be as durable or long-lasting as your fabric!);

3.  If possible, use a walking foot on your sewing machine to reduce seam slippage (most quilters use a walking foot and generic ones are often available from sewing machine retailers);

4.  Use a longer stitch and loosen the tension;

5.  Use a straight stitch foot instead of zig-zag for topstitching;

6.  Use low-heat fusbile interfacings - microfibers generally do not like high heat;

7.  Use "light" ironing techniques only.  Use a cool to warm, dry iron and press lightly.

Answer 3

What is happening is that the needle is bouncing off the fabric rather than penetrating far enough for the stitches to mesh properly.  You need to use a microtex needle of the correct size for your fabric, and fine polyester thread.  Mettler make a nice fine polyester sewing thread. Use a 2.5mm stitch length.
