DISRUPTIVE TECHNOLOGY OF SEWING: NEW ZARIF DOUBLE THREAD CHAIN STITCH TECHNOLOGY FROM 2021.

We invented the new ZARIF double thread chain stitch technology from 2021, by improving our ZARIF double thread chain stitch technology from 1994, for which US Patent No. 6095069 was issued in 2000 (see https://patents.google.com/patent/US6095069A).

Our new ZARIF double thread chain stitch technology from 2021 is the first and only technology in the world capable of qualitatively stitching any materials up to 8 mm thick with a small needle bar stroke length of 32 mm without adjusting the normal tension of threads, without skipping a stitch, without breaking threads, without breaking the needle and without deforming the needle tip.

In 1997, inventor Zarif Tadjibaev made a prototype ZARIF double thread chain stitch sewing machine, working on the basis of ZARIF double thread chain stitch technology from 1994, by reconstructing an industrial lockstitch sewing machine of class 1022 «Orsha» Company (Belarus).

From 1997 to 2021, we have implemented various know how into our prototype ZARIF double thread chain stitch sewing machine to improve our ZARIF double thread chain stitch technology from 1994 to the highest level, and our goal was achieved in 2021 with our new ZARIF double thread chain stitch technology from 2021.

Currently, our new ZARIF double thread chain stitch technology from 2021 is the first and only one in the world capable of replacing the lockstitch type 301 on a large scale with our new double thread chain stitch type 401, in which the loops of the top thread and the bottom thread are rotated 180 degrees.

In 2021, we also invented ZARIF double thread chain stitch technology with the formation of a stitch in any direction, i.e. a technical solution that allows ZARIF double thread chain stitch technology from 2021 to get a stitch when feed the material in any direction.

In addition, in 2021 we invented a very simple automatic thread trimming technology for our ZARIF double thread chain stitch technology from 2021.

DISRUPTIVE IN THE FIELD OF SEWING

Our new ZARIF double thread chain stitch technology, invented in 1994, has made the following disruptive in the field of sewing:

1. For the first time in the world, a rotary looper was used to form a double thread chain stitch type 401. Prior to our invention, the rotary looper was used only in the formation of a single thread chain stitch type 101.

As know, a rotary looper consisting of a single part is the only working body in sewing technology that is able to circle the loops of threads around its body, turning them 180 degrees with its tail. The rotary looper was invented by the American inventor James Edward Allen Gibbs in 1857, to form a single thread chain stitch type 101, where the looper makes one revolution per revolution of the main shaft of the sewing machine (see Patent US17427: https://patents.google.com/patent/US17427A ). In our new ZARIF double thread chain stitch technology from 1994, the looper makes two turns in revolution of the main shaft of the sewing machine.

Technology of single thread chain stitch type 101 from 1857.

2. For the first time in the world, a new double thread chain stitch type of 401 was obtained, in which the loop of the top thread and the loop of the bottom thread are rotated 180 degrees, due to the use of a rotary looper .

3. For the first time in the world during the downward movement of the needle, the collision of the needle with the looper during the formation of a double thread chain stitch is excluded.

4. For the first time in the world, an ordinary needle with one long groove was used to form a double thread chain stitch, i.e. a needle used in the technologies of forming a lockstitch, since the needle does not take part in the preliminary tightening of the loop of the top thread located in the previous stitch.

5. For the first time in the world, when forming a double thread chain stitch, two independently operating rotating two disc cam thread take-ups were used, which are used to feed and tighten the top thread and the bottom threads.

DISRUPTIVE IN THE FIELD OF SEWING

Our new ZARIF double thread chain stitch technology, invented in 2021, has made the following disruptive in the field of sewing:

1. For the first time in the world, sewing of various materials and their combinations with a thickness of up to 8 mm with a small needle bar stroke of 32 mm is performed.

2. For the first time in the world, sewing of various materials and their combinations with a thickness of up to 8 mm is performed without adjusting the normal tension of the top and the bottom threads

3. For the first time in the world, sewing is performed without skipping a stitch, without breaking the threads, without breaking the needle and without deforming the tip of the needle

4. For the first time in the world, sewing is performed with high reliability without the use of needle guards

5. For the first time in the world, it is possible to reduce the length of a double thread chain stitch to 0.5 mm in order to securely tacking the end of the chain seam using condensation stitches.

6. For the first time in the world, adjustment of the looper relative to the needle is excluded when switching from needle Nm. 130/21 to needle Nm. 60/8 and vice versa, since for the first time the maximum allowable gap between the tip of the looper and the needle is increased to 0.5 mm

7. For the first time in the world, it became possible to adjust the degree of tightening of the top thread loop in the stitch with the help of know how without changing the normal tension of the top thread:
- With a strong tightening of the loop of the top thread in the stitch, a normal stitch type 401 is obtained, which is used for a tight join of materials.
- With a weak tightening of the loop of the top thread in the stitch, an elastic stitch type 401 is obtained, which is used to obtain a smooth seam on light, ultralight materials and an elastic seam on elastic materials

8. For the first time in the world, the simplest and most reliable technology of forming a double thread chain stitch for stitching various materials and their combinations using a single line thread seam has been developed.

NEW ZARIF DOUBLE THREAD CHAIN STITCH TECHNOLOGY FROM 2021, WITH STITCH FORMATION IN ONE DIRECTION.

Our prototype ZARIF double thread chain stitch sewing machine from 2021 practically proved the operability of our new ZARIF double thread chain stitch technology from 2021 with stitch formation in one direction, i.e. along the groove of the needle plate made for needle and stitch formation.

Now we can start commercializing our new ZARIF double thread chain stitch technology from 2021 into various industrial sewing machines such as:

1. Industrial sewing machines with flat bed, cylinder bed and post bed.

2. Industrial sewing machines with any existing type of material feed, including needle feed of material, since, in ZARIF double thread chain stitch technology, the needle can move freely along the groove of the needle plate.

We can also start commercializing our new ZARIF double thread chain stitch technology from 2021 in various automated sewing systems, such as:

1. Automated sewing systems with automatic feed of material in one direction along the groove of the needle plate made for the needle and stitch formation.

2. Automated pattern sewing machines with a 360 degree rotating head with material feed in any direction according to the program, where the head and the lower part with the needle plate together according to the program synchronously rotate in the direction of material feed.

NEW ZARIF DOUBLE THREAD CHAIN STITCH TECHNOLOGY FROM 2021, WITH STITCH FORMATION IN ANY DIRECTION.

We also have a technical solution that allows our new ZARIF double thread chain stitch technology from 2021 to get a stitch when feed the material in any direction.

Based on this technical solution of ours, it is possible to develop various automated sewing machines with the feed of material in any direction, such as various automated pattern sewing machines, various automated sewing systems, quilting machines with one and two heads.

THE FUTURE OF OUR NEW ZARIF DOUBLE THREAD CHAIN STITCH TECHNOLOGY FROM 2021

Currently, our new ZARIF double thread chain stitch technology from 2021 is the most advanced in the world in the field of high quality sewing of various materials using a single line thread seam, and it will retain its leadership in the future.

Our confidence is based on the fact that the existing technologies for forming a lockstitch type 301 and a double thread chain stitch type 401, invented in the 19th century and currently used to obtaining a single line thread seam, have many disadvantages, which we have written in detail in our two articles available in the «Documents» section of our Website.

Many of the disadvantages of these existing stitch forming technologies are related to the technologies of forming these stitches, so in the future, regardless of how much they will develop, it is impossible to eliminate such disadvantages associated with stitch forming technology.

Our new ZARIF double thread chain stitch technology from 2021 is the first and only one in the world that is able to replace the lockstitch type 301 on a large scale with our new double thread chain stitch type 401.

We are confident that in the future it will be impossible to completely replace the thread method of joining materials with other methods non thread joining of materials, for example, joining using welding and glue.

This is due to the fact that using the thread method of joining materials, it is easy to make connections of any type of materials and a package of materials consisting of various materials with high quality, which is almost impossible to do with non thread methods of joining materials.

In the future, it is technically impossible to invent a new double thread chain stitch technology better than our new ZARIF double thread chain stitch technology from 2021, since it is very simple and capable of qualitatively stitching any materials up to 8 mm thick with a needle bar stroke length of 32 mm using a single line thread seam without adjusting the normal tension of threads, without skipping a stitch, without breaking threads, without breaking the needle and without deformation of the needle tip, with reliable tacking of the end of the chain seam by stitches condensation with a stitch length of 0.5 mm.
