twisting thread=skipped stitches?

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

Sailrite machine using V-46 thread on 1.5 ounce ripstop nylon geting skipped stitches during zig zag but not straight stitches. Switched  to v-69 (not v92 as originally posted) thread and needle change, no skipped stitches. Checked tensions, cap spring, needle bar mark, all seem just fine. I'm thinking that it is the v-46 thread. It wants to twist up on itself. I've tried pulling the thread off the cone vertically, horizontally and off the back of the cone, still twist. I didn't buy the thread from sailrite (writer turns a bit red here), got it off ebay. The thread is described as   
UV resistant V46 V-46 150D/3 High Tenacity Polyester Sewing Thread

Could the thread be causing skipped stitches? And if so is there any thing I could do to correct this?

Thanks
Jerry

	Hi Jerry, Actually surprised the V-92 worked in that setup at all. V-46 would be the right thread size for what you are doing. If the thread is twisting up noticeably then you can image how it acts/twists at the hook when the loop is formed. Before doing anything else I would get another cone of thread (Coats or A&E would be my recommendation). Thanks, Matt Sailrite

	Just ordered 8400 yards of the v46 white from Sailrite. I'll post the results once it gets here. Thanks Matt.

	I mis-remembered the the thread size, not 92 its 69. The v46 arrived today and it works beautiful. No skipped stitches.

	One thing to check is that the needle is not inserted with the eye in the proper orientation. The eye should be located to the side of the needle (facing left from the sewers p.o.v.). Possibly, if it is oriented in a different position, it puts a twist into the thread as it enters the fabric, engages with the bobbin thread, and is pulled back up through the fabric. Just maybe.
