Entanglement tester

August 31, 2011

Lawson-Hemphill Inc., has introduced its latest generation entanglement tester called the EST.

This new model utilizes Lawson-Hemphill's high-speed optical sensing technology introduced into the industry more than 23 years ago.The proprietary technology provides accurate measurements with user-friendly software that makes it fast and easy to perform high volume testing.The EST offers a unique feature of measuring and reporting the strength of entangled points at programmed steps of elongation.Very high volume testing is possible because test speeds of up to 400 m/min are possible.

The EST measures the draw tension, entanglements/meter, and related data for each incremental step programmed.All combined, the new EST entanglement tester supplies meaningful data necessary for quality assurance for downstream fabric processing of the filament yarn. This provides assurance the entanglements in the yarn are removed at the right levels needed in fabric formation.

Lawson-Hemphill also announced its latest generation HDK-DFT with Full Auto Changer, an instrument for simultaneously measuring draw force on a yarn while knitting the yarn for dye checks.The HDK-DFT is used both in routine testing of POY in direct spinning applications and for remelt spinning to optimize the process conditions.It is excellent for checking new master batches and confirming the color consistency with a spectrophotometer.
