Watch our 59-minute VIDEO (https://www.facebook.com/102104718352098/videos/713614462838153), so that you can practically see for yourself that our new ZARIF double thread chain stitch sewing machine from 2020 has made a BREAKTHROUGH in sewing with a single-line thread seam.

Our new ZARIF double thread chain stitch technology from 2020 begins a new era in sewing technology with single-line thread seam, which is very widely used than other types of thread seams in the manufacture of various sewing products, by widely replacing the lockstitch type 301 with our double thread chain stitch new type 401.

Our new ZARIF double thread chain stitch sewing machine from 2020, is the first and only one in the world that can replace the lockstitch type 301 with a double thread chain stitch type 401 on a large scale in the production of various sewing products.

Revolutionary achievements of the new ZARIF double thread chain stitch sewing machine from 2020:

1. Sews using a rotary looper and a needle with one long groove, i.e. the needle used in lockstitch sewing machines.

2. Sews using a new type of 401 double thread chain stitch, where the loop of the top thread and the loop of the bottom thread are rotated 180 degrees, thanks to the use of a rotary looper.

3. Sews without skipping a stitch, without breaking the threads, without breaking the needle and without deforming the needle tip.

4. Sews materials up to 9 mm thick with a needle bar stroke length of 32 mm.

5. Sews various materials without adjusting the normal tension of the top and bottom threads.

6. Allows switching from the normal new type 401, where the top thread loop is tightened strongly, to the elastic new type 401, where the top thread loop is tightened weakly, without adjusting the normal tension of threads using know-how.

7. With the help of normal new type 401 is provided by a dense join of materials.

8. With the help of elastic new type 401 sews light materials with a smooth seam and elastic materials with an elastic seam.

9. Allows switching from needle Nm. 130 to needle Nm. 60 without adjusting the looper relative to the needle, since the maximum allowable gap between of the looper point and the needle is 0.5mm.

10. Securely tacking the end of the chain seam from unraveling, by condensation of stitches, reducing the stitch length to 0.5 mm.

Our new ZARIF double thread chain stitch sewing machine from 2020 works based on our new ZARIF double thread chain stitch technology from 2020.

We invented our new ZARIF double thread chain stitch technology from 2020 by improving our ZARIF double thread chain stitch technology from 1994, for which US Patent No. 6095069 was issued in 2000.

We also invented automatic threads trimmer technology for our new ZARIF double thread chain stitch technology from 2020.

We plan to patent these two our new inventions in many countries around the world.

Our 59-minute video demonstrates our new ZARIF double thread chain stitch technology from 2020 without revealing the know-how.

Our video consists of the following seven sections:

1. Demonstration of sewing various materials.
2. Demonstration of sewing denim materials.
3. Demonstration of sewing medium materials.
4. Demonstration of sewing light and elastic materials.
5. Demonstration of sewing with extra thick top thread.
6. Demonstration of sewing leather materials.
7. Demonstration of performing broken and curved seams.

We are currently looking for industrial sewing machine manufacturers willing to become our Partner on mutually beneficial terms to develop, manufacture and mass-produce an industrial sample of our ZARIF double thread chain stitch sewing machine from 2020.

In addition, based on our new ZARIF double thread chain stitch technology from 2020, other types of industrial sewing machines can be developed and mass-produced depending on market demand, with various other types of material feed and platform shape (cylindrical platform and columnar platform).

Also, based on our new ZARIF double thread chain stitch technology from 2020, can develop and mass-produce various automated sewing systems with material feed in only one direction and various automatic templates sewing machines with a 360-degree rotation of the head to form a stitch when feed the material in any direction, i.e. in the 360-degree range.

We very interested to cooperate with your Company in the development and mass production of various automated pattern sewing machines with 360-degree rotating head for sewing in any direction, working on the basis of the new ZARIF double thread chain stitch technology from 2020, for the production of clothing, upper part of shoes and sneakers, auto seats and auto airbags, etc.

In addition, our new ZARIF double thread chain stitch technology can successfully solve the problems of sewing automation, we wrote about this in detail in our next two articles published in 2018 in the Japanese Magazine «The Fashion Machine News»:

1. Problems of sewing automation and their solutions with the help of new ZARIF double thread chain stitch technology.
2. The new ZARIF double thread chain stitch technology is the simplest, reliable in operation and develops sewing automation.
