ABOUT US

The main activity of our company «ZARIF SEWING MACHINE CO., LTD.» aimed at the commercialization of our innovative invention «New «ZARIF» double thread chain stitch technology».

We invented our new «ZARIF» double thread chain stitch technology in 2012 by improving our old «ZARIF» double thread chain stitch technology, invented by us in 1994 (U.S. Patent No. 6095069 from 2000).

Our new «ZARIF» double thread chain stitch technology surpasses in universality of sewing various materials all existing sewing technology (see our video «The Worldwide first universal «ZARIF» double thread chain stitch sewing machine»).

In addition, our new «ZARIF» double thread chain stitch technology significantly expands the area of application of the double thread chain stitch, by replacing lockstitch.

As is known, replacement lockstitch on the double thread chain stitch leads not only to increased productivity due to the lack of changer bottom thread bobbin will also increase seam strength.

On the basis of our new «ZARIF» double thread chain stitch technology, can be develop various new universal industrial sewing machines and automated sewing systems that have no analogues in the World (see section «Application of new sewing technology»).

In addition, in the World only our new «ZARIF» double thread chain stitch technology, allows to receive special new non-raveling, high breaking strength and highly elastic double thread chain seams.

In 2012, we also invented the technology of automatic threads trimming for our new «ZARIF» double thread chain stitch technology.

We plan to patent our new innovative inventions «New «ZARIF» double thread chain stitch technology» and «Technology of automatic threads trimming» in many countries of the World.

DEVELOPMENT OF MASS PRODUCTION OF DIFFERENT SEWING PRODUCTS USING THE NEW «ZARIF» DOUBLE THREAD CHAIN STITCH TECHNOLOGY

Our new «ZARIF» double thread chain stitch technology opens new possibilities for development of mass production of different sewing products.

  1. Productivity at the expense of reduction of an idle time of the sewing machine, associated with refueling of threads increases:
    • There is no loss of time for frequent refueling of the bottom thread which is present at lockstitch technologies.
    • There is no loss of time for refueling of threads at their breakage, as our new «ZARIF» double thread chain stitch technology allows sewing practically without breakage of threads if to use the threads which do not have thick places and knots.
  2. Productivity at the expense of reduction of an idle time of the sewing machine, associated with the regulation of the tension of threads at transition to other type of a material:
    • Is sufficient to establish the normal tension of threads to sew a different materials with thickness up to 8 mm without thread tension adjustment.
    • To increase the smoothness of the seam on light materials and elasticity of a seam on the elastic material sufficient to pass from a normal stitch to an elastic stitch with the help of know-how, without adjustment of a tension of threads.
    • For a very dense join of materials is sufficient to increase only tension the top thread.
  3. Productivity at the expense of reduction of an idle time of the sewing machine, associated with adjustment of working units increases, at transition to other type of a material and needle number:
    • There is no loss of time for adjustment of needle bar at transition to other type of a material as the height of lifting of a needle from the lower position has a constant for all types of a material thickness up to 8 mm.
    • There is no loss of time for adjustment of looper concerning a needle at transition to other number of a needle as the maximum clearance gap between the nose of the looper and needle is equal 0,5 mm.
  4. Sewing machine becomes universal:
    • One model of the sewing machine with a minimum needle bar stroke of 32 mm, is capable to sew materials thickness up to 8 mm.
  5. Increases the seam quality:
    • New «ZARIF» double thread chain stitch technology can sew without skip stitch with a 100% guarantee, which is very important for chain seams, as all the chain seams are very easy to unravel, where there are skipped stitches.
    • New «ZARIF» double thread chain stitch technology which can qualitatively bartacking the end of seam, condensed stitches reducing length of a stitch to 0,5 mm.
    • The World's only new «ZARIF» double thread chain stitch technology capable of being dense and very dense joins the materials using a double thread chain stitch.
    • Very easy using the know-how can to pass from a normal stitch to an elastic stitch to increase the smoothness of the seam on light materials and elasticity of a seam on stretchy materials.
    • The World's only new «ZARIF» double thread chain stitch technology can get specials new non-raveling, high breaking strength and highly elastic double thread chain seams.
