Application
The Yarn Wrap Reel is used to create skeins of yarn with a predetermined length and number of turns, ideal for yarn count and strength testing. Available with a 1-meter, 36-inch, or 54-inch circumference collapsible swift (please specify). The wrap reel comes complete with a yarn package stand and a pre-tension device, and is equipped with a pre-determined counter for accurate measurements.
Testing Method
Determination of the Yarn Count Using the Wrap Reel
Objectives
To determine the yarn count using the wrap reel.
Equipment
- Yarn Wrap Reel Machine (VIT 360)
- Yarn Count Tester (VIT 361)
Procedure
- Place the given yarn sample on the wrap reel.
- Start the wrap reel yarn testing process.
- Weigh the yarn using the yarn count tester.
- Convert the weight unit (from grams to pounds if necessary).
- Record the data and calculate the yarn count using the following equation:
Yarn Count=Length in yards×Weight unit840×Weight in poundstext{Yarn Count} = frac{text{Length in yards} times text{Weight unit}}{840 times text{Weight in pounds}}Yarn Count=840×Weight in poundsLength in yards×Weight unit
- Calculate the average yarn count for the sample.
Conclusion
The procedure for determining yarn count using the wrap reel is straightforward. Attention must be given to the units used, particularly when converting from grams to pounds.
