Shanghai Yu Hui Has Developed The World'S First Foam Foam Dyeing Machine.

Recently, Shanghai

Because foam is a very sensitive physical state, foam mixing and mixing technology is the foundation of foam application, and puts forward high requirements for equipment design and operation.

The application of foam to fabric finishing and dyeing has always been a technical problem.

After many years of research, Shanghai Yu Hui has created the international leading "stirring vortex streamline density theory", that is, VLDC theory. Based on this theory, the rotor and stator stirring device designed to play a very important role in the application of foam dyeing.

The theory provides a solid theoretical basis for the distance between the stator teeth of the stirred rotor, the thickness and length of the stirring tooth, the mixing space, the stirring speed and the matching flow design.

Shanghai Yu Hui uses foam technology to creatively solve the problem of unevenness of bubbles in the horizontal direction. On the basis of a large number of actual production, the world's first spray dyeing machine was developed, that is, the spray foam dyeing machine.

Combined with the spray dyeing technology of "Yu Hui" patent, the dyeing process of reactive dyes is shortened from traditional rolling, drying, rolling and steaming to spray drying of short process.

At present, froth dyeing with reactive dyes has begun industrial application, and has achieved gratifying results.

And traditional
