Which type of stitch do i need to use to seal a frayed edge

If your Janome 805 sewing machine is having trouble sewing through batting, there are a few things you can try:

1. Use the right needle: Make sure you are using a needle that is appropriate for the thickness of the batting you are using. A needle that is too small or too dull may struggle to penetrate the batting layers.
2. Adjust the tension: Experiment with adjusting the tension on your sewing machine. If the tension is too tight, it can cause the fabric and batting to pucker, while if it's too loose, the stitching may come out uneven. Refer to your sewing machine manual for instructions on how to adjust the tension.
3. Use the right stitch length: Adjust the stitch length to a longer setting, which can help the needle to penetrate the batting more easily.
4. Try using a walking foot: A walking foot can help feed the batting evenly through the machine, which may help prevent bunching and puckering.
5. Use a sharp blade to trim the batting: Before sewing, make sure the edges of the batting are clean and even. Use a sharp blade to trim any frayed or uneven edges.

If none of these tips help, it's possible that there may be an issue with your sewing machine that requires a professional repair.

Top thread is "frayed"?

Could be tension is too high, problem with needle, needle wrong type, other.

Does it straight stitch ok using same fabric, thread, needle, bobbin, and tesnsion?

Top thread? Mis-threaded, wrapped around a thread guide or the spool pin, top tension too tight. If the thread is fraying/shredding, possibly a damaged or incorrect needle, a burr or sharp edge catching the thread, or old/bargain bin thread.

Suggest removing the thread completely from the machine.
Install a brand new needle (needs to be compatible with the thread and fabric being stitched).

ALWAYS RAISE the presser foot and rethread from the beginning.
Verify the thread path is correct.
Set the top tension to the midway point and retest the machine.
Tweak the top tension so the top and bobbin threads meet in the middle of the fabric.

AVOID old or bargain bin thread. You may also try a different brand of thread. Some machines work better with one brand than another. If you can see little fuzzies projecting from the thread, get rid of it. All those fuzzies contribute to lint build-up in your machine and is not the best type of thread to use.

Why is my thread breaking

..

Be sure that you are using only fresh, good quality thread. Old or bargain bin thread will fray easily. Does the thread have little hairs (fibers) sticking out? If so, get rid of it. Try a different type of thread, ie polyester thread. (FWIW, Coats & Clark used by a stand-by, but it is a lesser-quality thread these days.) Be sure to use the same thread in the bobbin--polyester thread will tend to cut cotton. Try flipping the thread spool over so it feeds off in the opposite direction. Make sure the machine's bobbin area is clean of any lint or debris. The tension may be too tight. The thread may be mis-threaded or the thread is restricted somewhere, ie wrapped around a thread guide or the spool pin. Be sure the thread is running through the thread guide immediately above the needle. Remove the thread and rethread from the beginning. You might try a different type of needle, ie top-stitch needle. Top-stitch needles have a larger scarf that will protect the thread as it pierces the fabric multiple times before forming a stitch. A Top-stitch or Metafil needle has a larger eye to accommodate bigger thread. Are you sewing unusually coarse fabric? It is abrasive and could be causing the excessive fraying.

If the fraying continues, there may still be a burr somewhere.

All About Needles

Use a different stitch, use the triple zig zag or serpentine stitch so he needle is going through the fabric three or four times as it swings left to right.ma plain zigzag, because thread is tensioned, will pull lightweight fabric up. Try another raw edge finish, such as french seams, pinking shears or overcasting stitch. Of course for professional looking seams an overlocker (serger) is the answer as it has blades that trim the fabric edge and neaten with 2, 3 or 4 thread seam, encasing the raw edge.

Change your needle, and try a different type of thread. You may also need to use a larger needle size to allow for the type of thread you're using.

I'm a bit confused, this isn't a serger machine as far as I can see. So do you mean an overcasting foot where you sew a XXXXX type stitch along the edge of the fabric? The overcasting foot just helps you to line up the fabric edge and sew over it neatly.

if you go to this page http://www.sewingpartsonline.com/necchi-6022-sewing-machine-parts.aspx
there is an instruction manual for sale.

http://sewmamasew.com/blog2/2009/06/feet-feet-feet/ is also a great resouce on sewing machine feet with good photos of what they are used for.

Here is a video of overcasting foot in action http://www.sewingmachine-sales.co.uk/sewing_machine_info/video/34/adjustable-overcast-foot.html

If you are wanting to sew knit fabric then you just need to use a small zig zag stitch and a ball point needle to put elasticity into the seam. Or your model may have a stretch stitch, where the fabric is moved forwards and backwards during the stitch formation to add some elasticity.

Sewing elastic stretched onto fabric is a bit different with a SM, can be fiddly and hard to keep everything lined up nicely and stretched. Some machines have a little device which clips onto the needle plate in front of the needle that you can feed elastic through and tighten it to tension it, then just use a three step zig zag stitch to seam over this onto your fabric. But I don't know if Necchi has such a thing, your needle plate would need holes in front for it to clip into. Elna had these on their swiss machines in the 80's but haven't seen a similar device for a while.

Hope I've answered your question and not completely misunderstood your problem. Purchasing a manual is often the best way forward when a machine is unfamilar. Or www.sewing.about.com is great resource.

A overlock machine helps you clean finish the seams. You can do many things with a overlock It can cut your sewing time down. The sewing machine is good for many thing too,Mostly the construction of the garment. I have three machines. A indstrialstraight stitch, a home machine and a overlock.Al for different tasks.

Try stitch length 2 (of 5) width 2 (of 5) and a zig zag stitch.
