A new dyeing method for the manufacturing of textile fabric is proving popular with clothing brands looking for a cheaper, more durable option for its customers.
The dyeing is called pulsing collagen and it’s being used by brands like L’Oreal and Jil Sander.
“It’s a new technology, a breakthrough technology,” says the head of the company that develops the process, Prof. Marko Mijalkko.
Prof Mijanko says the new dye is a bit like a “melt” or “swish” of the material. “
In the process of creating collagen, the process is not very intensive, it is quite gentle, but it does require a very large amount of time, as well as high temperatures.”
Prof Mijanko says the new dye is a bit like a “melt” or “swish” of the material.
He says the process “pulsates” collagen in a very gentle way and that it produces the “stability” and “stretch” that people are looking for in their garments.
Prof. MarkO Mijallko, professor at the Institute of Molecular and Biomolecular Engineering at the University of Cambridge, is the lead scientist behind the pulsing method.
He has used pulsing for the past 10 years.
“We use this method to create collagen,” Prof Mijanykko says.
We use a very small amount of dye, and then it’s left to do the rest of the manufacturing in a heat bath, which produces a large amount, about 100 millilitres of collagen per litre of fabric.
Then we apply this collagen to a fabric, which has been treated with a chemical to reduce the structure of the collagen.
That’s the key point, he says.
The collagen in the fabric stays flexible.
“And then we melt it in a small amount and we create the stable collagen, that stays on the surface of the fabric.”
This is the key to the longevity of the product, Prof Mixkko said.
When it comes to creating collagen for garments, Prof JilSander says it’s important to understand what the process actually produces.
Its a protein that is part of the body’s collagen, it’s in the skin and the connective tissue, he said.
And it’s also used in many tissues in the body.
It’s made from collagen and in the textile fabric it can be used to produce a strong, elastic fabric, Dr. Jilsander says.
“You can have a very good product in a thin piece of fabric,” he said, “but you have to make sure that it’s very flexible, that the fibers are stretchy.”
“When you use a lot of collagen in an elastic fabric like a sweater, you have a lot more flexibility in that sweater,” Dr Jilso said.
“But if you have too much collagen, your sweater might not stretch.”
The process that we’re going to do here is very gentle and gentle,” he continued.
Pulse-Pulsing means that, instead of the normal process of heating the collagen with a dye, the dye gets absorbed by the protein and the collagen stays flexible, Prof Marko said.””
The result of this is that the collagen does not become stretched,” Prof. Mijalekko said, but “that it remains very flexible.”
Pulse-Pulsing means that, instead of the normal process of heating the collagen with a dye, the dye gets absorbed by the protein and the collagen stays flexible, Prof Marko said.
“This is why the product is so flexible,” he says, explaining that it has “stretching properties”.
“You don’t get a very flexible fabric,” Prof MarkO said.
He added that this process is very much like the way that a silk fibre is made.
In silk, the protein in the fiber is actually very flexible and can stretch, but if the protein is exposed to heat, it will become very brittle.
“In this process, the proteins are heated to the temperature of the dye, so they can stretch,” he explained.
The final product, he added, “is really a very stable, elastic product.”
There are many other uses for the protein, including in the manufacture of textile-specific products, Profs Mijailko and Jils Sander said.
For instance, the gel made from the collagen is also used as a fabric treatment in the making of condoms, which the two companies are making for men.
Dr Jiland said that the process makes it possible to make a high-quality product, “which is also more economical”.
“We make a gel that is not only elastic, but also stretchy,” Dr Mijayko said of the process.
“And then it can easily be worn.”

Prof Jil, Dr Sander and Prof Markallko are currently working on developing the gel.
