Changzhou Hongda
How to build the world’s leading
intelligent weft-straightening and warping & pattern
arranging frame?

In the past 30 years, he has occupied
the commanding heights of technology
and market of textile and dyeing & printing
industry with independent innovation.
He relied on down-to-earth dedication
for fruitful achievements. The company
has become not only national high-tech
enterprises with very size and strength,
specialized in the R&D and manufacturing
of textile and dyeing and finishing intelligent
control technology, and also won the
honors of “integration of IT and industrialization”
pilot demonstration enterprises
of national printing and dyeing digital
system technology R&D center and Chinese
Ministry of Industry and Information
Technology. He is Gu Ren, chairman of
Changzhou Hongda Science and Technology
(Group) Co., Ltd. How does Hongda
company achieve rise in a falling market?
What is the key of products to leading the
market? The reporter interviews him with
these issues.

China Textile: Technology research
and development has been the greatest
advantage of Hondda company, so
can you introduce the details about the
world’s leading intelligent weft-straightening
and warping & pattern arranging
frame?

Gu Ren: In the maching process,
it often appears weft bending and skewing,
with adjustment by photoelectric abb finishing in the past, but with the everchanging
market demand, the fabric is
more and more complex and customers’ requirements
of the equipment are also more
and more high. For example, after fabric
like jacquard weave forms pattern, it’s inadequate
just to check the straightness of
weft yarn, then how to detect the straightness
of pattern? In terms of customers’
demands, we have HVMC-15 series intelligent
weft-straightening and warping &
pattern arranging frame with independent
intellectual property rights. Hawk vision
series of intelligent weft-straightening and
warping & pattern arranging frame solves
the distortion problems of print fabric,
jacquard cloth, lace fabric and other woven
and knitted fabric for the first time in the
world.

China Textile: In addition to the
production and development of intelligent
weft-straightening and warping &
pattern arranging frame, what leading
technology and equipment are the company
promoting?

Gu Ren: We have been engaged in
the R&D and production of dyeing and
printing equipment for nearly 28 years,
and production is mainly concentrated in
key process parameters online testing and
automation of the whole process, intelligent
and other fields. We launch a series of
automated and intelligent products, such as
setter automatic overfeeding and intelligent
weft density control system, intelligent
density instrument, PH automatic extraction
instrument etc.. The intelligent dyeing
and printing production line realizes
automatic production in the whole process.

At present, the main production is equipment
and software control system, but
more is inside control equipment, which is
matched with the host or for upgrading of
equipment.

China Textile: Recently, market demand
has changed, what are the focuses
of the company on the R&D of products?

Gu Ren: The company will still focus
on intelligent in the future. In addition to
dyeing and printing, we also have done
the single spindle detection to control yarn
breakage and twist. The main purpose is
to reduce labor intensity. The system will
display which spindle with yarn breakage,
and the operator just needs to pick it
up. We generally think that the speed of
100 thousand spindles is consistent, but
in fact, there are differences among them.
General operators and technicists are not
clear whether the difference meet the requirement
of process design, but operators
immediately know with this system. It
needs to be maintained and repaired, if the
spindle exceeds the scope of the required
target.
