HOT DRAW KNITTER

LH123 HDK

The uniformity of POY (Partially Oriented Yarn) is essential. The irregular POY packages need to be identified and prevented from entering the production line. The textile industry relies on the knit-dye-grade method to qualify the POY packages. Preparing uniform knit samples is the most critical step during this process.

The Hot Draw Knitter, HDK, is a high-speed, precision knitting machine with a built-in stitch control system to check the uniformity and the consistency of the POY production quickly and accurately. It is ideal for use in production control and R&D labs as well as dyeing plants.

POY, MOY and LOY samples from 10d up to 2000d can be knit with the HDK. (Please consult Lawson Hemphill to knit higher or lower denier yarns).

The machine can be equipped with a non-contact Vapor heater and contact Pin heater to allow testing both polyester and nylon yarns. Precision Draw ratios are available from 1:1 to 1:3, with increments of 0.05.

A Draw Force Test option is available to measure the tension on the yarn as it is being drawn and knitted. With the Draw Force measurement, the HDK becomes the only instrument that provides a knit sample and draw force results on a package at the same time. This test complies with ASTM 5344, Standard Method for Extension Force of Partially Oriented Yarn.
