ISO 17202:2002 Textiles — Determination of twist in single spun yarns — Untwist/retwist method
The ISO 17202:2002 Textiles standard describes a method for determination of twist in single spun yarns. The untwist/retwist method uses a set of two identical yarns, each of which has been spun into one end of a length of filament. One yarn is unwound from the spool and passed through the other yarn, so that they are twisted together. The twist is then measured by rotating the two yarns around their longitudinal axes.
What is ISO 17202:2002 Textiles?
ISO 17202:2002 Textiles is a standard that establishes the determination of twist in single spun yarns. It also provides a method for untwisting and retwisting yarns to determine the original twist.
The twist in a single spun yarn affects the strength, durability, and how well the yarn resists felting. The higher the twist, the stronger the yarn will be, but it also increases the risk of felting.
This Standard Textiles is a standard that establishes a method for untwisting and retwisting yarns to determine their original twist. This is important because it allows textile producers to more accurately adjust the twist in their yarns before they are spun.
If you are producing textiles or spinning yarns, it is important to comply with this standard Textiles. By doing so, you can ensure that your textiles are of high quality and resistant to felting.
What are the requirements of this standard?
ISO 17202:2002 Textiles is a standard that defines procedures for determination of twist in single spun yarns. This standard has certain requirements which must be followed when performing the untwist/retwist method.
The untwist/retwist method can be used to determine the twist in a single spun yarn. The procedure involves unwinding the yarn from the bobbin, and then retwisting it. The twist in the yarn can then be determined by comparing the unwound and retwisted sections of the yarn.
The requirements of ISO 17202:2002 Textiles include following guidelines when performing the untwist/retwist method:
1) The yarn must be unwound in a straight line from the bobbin.
2) The yarn must be re-twisted without breaking or damaging it.
3) The twist should not change after being re-twisted.
4) The difference between the unwound and retwisted sections of the yarn must be measured accurately.
What are the benefits of this standard?
ISO 17202:2002 Textiles is a standard that specifies methods for determination of twist in single spun yarns. Twist is an important property of yarn because it affects the performance of fabrics made from the yarn.
There are several benefits to using ISO 17202:2002 Textiles when determining twist in single spun yarns. First, it is a standardized method that can be used by all parties involved in the textile process, from spinners to fabric producers. This makes it easier for everyone to understand and comply with the standard.
Second, using ISO 17202:2002 Textiles can improve the accuracy of the twist measurement. By using a consistent method, it is easier to determine the exact amount of twist present in a single spun yarn. This can help to ensure that fabrics made from the yarn are of high quality.
Finally, using ISO 17202:2002 Textiles can reduce cost and time associated with textile production. By specifying a standardized method for determining twist in single spun yarns, there is less need for manual intervention and error. This can save both time and money for fabric producers.
