My 2nd Patent: Physics of Yarn Dyeing/ Density Measurement And Sorting of Soft Packages.

Because Yarn Dyeing is a Physio-Chemical Process. The Physics of Dyeing is as important as Chemistry of Dyeing.

The Physics of Dyeing Comes by managing the Uniformity of Density achieved by:

1. Angle of Wind, which ensures the same number of layers from top to the bottom of the package.
2. The Shape of the package, which has to be cylindrical and compressible. Compression is the only phenomenon which ensures that the unevenness of the soft packages from precision winder is neutralized.

However, there is still no such practical system, which measures and sorts out the density range of the soft packages as required for good dyeing.

Herein my Solution

Co-ordinates For Volume

The imaging technology captures the volume if the soft package via a camera.

The Soft Package is placed in position and the machine started. The Pusher arm pushes it under the DMS, where the camera captures the volume and the weighing machine under, captures the weight.

The Density is then worked out by the computer and the sorting program pushes the soft packages into bins.

The Off Density packages , viz above are pushed into one bin, the below in another bin and those within the range come straight to the end bin.

This way the dyer can then dye, the above range soft packages together and the below in another lot, without the need of rewinding. Also, the RFT percentage improves on account of the correct physics of yarn dyeing.

The production rate is around 6 nos per minute or say around 10 tons per day.

Currently under Beta Testing and should be available to market in another 3 months time. Expression of Interest is welcome.
