Lawson-Hemphill showcases latest QC and lab testing instruments.

Lawson-Hemphill Inc., an industry leading supplier of QC and lab testing instruments, will be exhibiting their latest equipment in Hall 2 booth number H2-B169.

EST - entanglement tester

The show highlights include the latest generation entanglement tester called the EST. This new model utilizes Lawson-Hemphill's high speed optical sensing technology introduced 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 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 that the entanglements in the yarn are removed at the right levels needed in fabric formation.

HDK-DFT with Full Auto Changer

The latest generation HDK-DFT with Full Auto Changer is a unique 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 masterbatches and confirming the color consistency with a spectrophotometer.

Lawson-Hemphill will be showing the HDK-DFT integrated with their latest generation SAK autopackage changer.

Fiber Analysis Knitter

Several orders were received this year with the SAK Auto package changer integrated with the FAK (Fiber Analysis Knitter) which is widely viewed as the standard lab knitter for spun and filament yarns. This automation combination provides a high degree of automation and integration with automatic packing systems. The FAK is widely used by institutes, machinery companies, and dye houses because it provides precise and consistent fabric samples due to the proprietary tension and stitch length control.

Because of this precision and guaranteed reproducibility, it is considered reliable with spectrophotometer usage. This saves losses since it is easier to reproduce the same colors and confirm them by accurate spectrophotometer readings.

Lawson-Hemphill will also be showing the ADF (Automatic Tensile Tester), their FST (Force Shrinkage Tester), the DMT (Dynamic Modulus Tester), as well as traditional lab instruments (friction testers, denier reels, twist testers, etc.).
