MT - OASYS^® Fancy Yarn Module
 

Since 10 years the OASYS^® System has been the tool of choice for slub yarn spinners and fabric manufacturers that use slub yarns. The optical measuring system has proven to be the system of choice for the evaluation of slub yarns. The industry philosophy is that one must measure what is later actually seen in the fabric as an effect. This OASYS^® in fact does due to the optical measurement as opposed to capacitance systems which only concentrate on the yarn volume. Top spinning machine manufacturers such a Schlafhorst’s Fancynation^® and Loepfe have actually incorporated portions of the OASYS^® systems in to their product lines.

In an effort to support the industry Zweigle has developed a number of tools for measuring slub yarns. These tools allow the industry to document slub yarn parameters statistically and graphically. Additionally the OASYS^® system supports in the design of new slub yarns and fabrics by creating yarns in a virtual environment. These yarns can then be used to make fabric simulations in OASYS^®.

Fancy Tools in OASYS^®
 

The yarn analysation portion of the program displays the complete measured yarn profile. The operator can easily take measurements on any portion of the yarn up to 10.000 m using the slides. It is possible to zoom onto specific portions of a slub and to adjust the zoom or the magnification of the amount of yarn which is under investigation. Using the locator function consisting of two red and blue lines detailed measurements of the yarn can be gained in record time. This allows for the determination of slub length, slub thickness, pause length and slubing patterns.

Also available in OASYS^® are graphs which can show slub information on spectrograms and histograms. Histograms show the slub thickness and their distribution while the spectrogram is a tool to determine the periodicity of the slubs. Used together this information is helpful in the development of new slub yarns and the archiving of different slub yarns and their parameters.

It is now possible to copy slub yarns in a few minutes time. After measuring a yarn all relevant parameters can be gotten from the before mentioned tools and then easily entered into various slubbing systems.

Creating Slub Yarns

OASYS^® allows for the creation of slub yarns in a virtual environment. Design and sampling costs along with quick reaction times have long been a focal point. OASYS^® serves as an excellent tool to reduce costs associated with sampling. Aside from actual measured yarns it is possible to create slub yarn in a virtual environment. Using the yarn generation program all parameters of a slub yarn can be created. These virtual yarns can then be placed in various simulation programs to see the appearance of slubs in a new fabric design before the yarn has actually been spun.
