Unisizer KS-7

The KS-7 was developed to size various fibers, spun yarns (cotton, silk, hemp yarns, etc) as well as a variety of filament yarns to prevent fuzz, improve strength and sustain elongation properties.

Linking three processes (coating/sizing, drying, and winding) into one machine dramatically improves efficiency, quality, and contributes to saving space. The KS-7 is ideal for the recent trend of manufacturing a wide variety of fabrics in small lots, at minimum time, with frequent style change.


1.  Applies sizing uniformly to the yarn

  • The yarn is submerged in a sizing bath

 2.  Gentle to the yarn

  • Mechanisms (sizing, roller, drying, reel, winding drum) throughout the yarn path are synchronized so that excessive tension is not applied, and fine yarns or elastic yarns can be processed

 3.  Easy to operate

  • Touch panel allows for centralized control

 4.  No damage to the yarn

  • The taper on the drying reel can be adjusted to accommodate various yarn types

 5.  Process speed is fast, output is high

  • The yarn runs through the chamber for 380 meters, thus drying efficiently is high speed can be set high and temperature can be set low

 6.  Easy to clean

  • The sizing bath is easy to clean.  The back door of the drying chamber can be opened for easy maintenance and cleaning
