In 1994, ZARIF Tadjibaev was the first to invent the new ZARIF technology for forming a double thread chain stitch type 401 using a rotary looper. This technology was patented in 2000 under US Patent No. 6095069. 

ZARIF Tadjibaev, having launched a prototype of the ZARIF sewing machine based on the ZARIF sewing technology from 1994, has been working since 1997 to improve the ZARIF sewing technology from 1994 to make it an ideal technology for straight stitch sewing. 

And in 2023, ZARIF Tadjibaev achieved his goal by inventing the ideal ZARIF double thread chain stitch technology with a rotary looper for sewing straight stitches. 

We are a small technology company founded in 2012 by ZARIF Tadjibaev, and we are not in a position to put our ideal ZARIF double thread chain stitch technology into production by mass producing an industrial version of our innovative ZARIF sewing machine. 

That's why we've launched a crowdfunding campaign to raise funds to mass produce an industrial version of our innovative ZARIF sewing machine. 

You can find out more about our campaign and support us on GoGetFunding (https://gogetfunding.com/zarif). 

Please consider making a donation to support our project. 

Your donation can be any amount, but if it is $10 or more, you will become a pre-order customer for the industrial version of our innovative ZARIF sewing machine and enjoy a 10% discount on the price of the machine. 

The number of industrial versions of our innovative ZARIF sewing machine you can purchase at this discounted price is equal to your donation amount divided by 10. 

Once we have raised the necessary funds, we will start setting up production and you will be able to buy your order at a 10% discount when we start mass production of the industrial version of our innovative ZARIF sewing machine.
