Find the dye that holds the color permanently

It is no longer necessary to divide colored clothes and white clothes when washing housewives' laundry when scientists have invented a new dye that will never fade.

It was a disaster for any day of washing if only one red slip was left in the pile of white and made them turn pink.

However, British chemists have invented a new dye, which can permanently stick to fabric, so that colors do not fade over time.

Most traditional dyeing methods are based on the principle that penetrating dyes and entanglement within fibers only create fabric. However, after a while, they will leak out especially when washing at high temperatures. The new dye will bind to the chain of molecules that make up the fabric.

" We have developed this new technique to use for synthetic fibers - fabrics made up of long chains of molecules called polymers and very difficult to dye, " Telegraph quoted Dr Patrick McGowan, University of Leeds, a member of the dyeing engineering team, said.

" In this way, we fix the color into the polymer molecules as if they were formed, making the coloring itself part of the material ."

Fabrics dyed with new techniques have been tested to wash water at a temperature of 60 degrees Celsius but do not fade.

McGowan said this technique could be applied to both hair and natural fiber dyes.

In addition, the team said their new dyeing method reduces harmful pollutants harmful to the environment, low waste and low energy use.

" Men benefit a lot when their shirts are not in danger of turning pink when washing with red socks, " said Justine Roberts, owner of Mumsnet online shopping.
