CRIMP

Texturizing is an important step that adds natural fiber feel to synthetic yarns by introducing bulk and crimp.  Traditionally, these properties were measured using Skein method, which by design, can only measure skeins of yarn at a time.

 

The introduction of the yarns with different crimp levels into the same fabric will cause light to reflect differently, creating a stripy appearance due to variations in bulk.  When measuring the Crimp and Shrinkage, TYT-E can apply as low as 1mg/denier tension on the yarn to measure the slightest change in crimp and shrinkage.

 

Lawson Hemphill developed the Textured Yarn Tester with Electronic Servo Drive , TYT-E, to overcome the disadvantages of the Skein Method by reducing test time (1000+ pkgs/8hours with a Package Changer).  TYT-E also has an exclusive ASTM Standard D6774, “Standard Test method for Crimp and Shrinkage Properties for Textured Yarns using a Dynamic Textured Yarn Tester” and it conforms to the Chinese Standard GB/T6508-2001.

 

TYT-E provides a dynamic platform that allows measuring every section of the yarn to simultaneously determine four yarn properties, including Total Recovery (Total Contraction), Fiber Shrinkage, Fiber Crimp and Entanglement.

 

In addition to providing direct feedback on yarn quality during production, TYT-E can be placed directly in the yarn packaging area to qualify outgoing packages before final shipment.

 

Windows based TYT-E software program features user-friendly touchscreen interface and it provides complete statistical report with accept/reject limits and built-in ability to connect to a network to control the production parameters remotely.
