How the filter bag machines affect the sewing thread of filter bags?

How the filter bag machines affect the sewing thread of filter bags?

The filter bag machines include automatic filter bag sewing machines, semi-automatic filter bag sewing machines and manually filter bag sewing machines.

Shanghai Filterworkshop Co., Ltd is one filter bag manufacturer and filter bag factory from China who is with more than 20 years in the filtration field.

For high temperature dust collector filter bags or dust filter bags, such as nomex filter bags, if you are using automatic filter bag sewing machines or semi-automatic filter bag sewing line to sew nomex filter bags, better use ptfe sewing thread to replace nomex sewing thread. Since the sewing speed of automatic machines and semi-automatic machines are higher than manual ones, it has high request of thread strength. Because ptfe sewing thread is much stronger than nomex thread, so better use ptfe sewing thread to replace nomex sewing thread.

If you are using manually sewing machines to sew nomex filter bags, then using nomex sewing thread is fine.

How to choose correct sewing thread for sewing dust filter bags?

How to choose correct sewing thread for sewing dust filter bags?

Dust filter bags include polyester, polypropylene, acrylic, nomex, pps, fiberglass, p84, ptfe filter bags.

To choose correct sewing thread for different dust filter bags, we need to consider the temperature resistance and chemical resistance of bag material.

Filter bag sewing thread working performance shall be same or better than filter bag material under same working condition.

Generally, what material of filter bags, the sewing thread will be same.

But for high temperature filter bags, if sewing filter bags automatically, such as nomex filter bags, fiberglass filter bags, p84 filter bags, or filter bags treated with ptfe lamination, better use ptfe sewing thread, since sewing speed is high, it require sewing thread is stronger, or else, thread will break easily.
