@mclaincausey I'm probably being dim, but how does this relate to the IHSH-07? That's the Hickory Western right?

[mclaincausey]

It is @T4920 ; it is sulphur dyed (typo here I see):

@mclaincausey ahhh I thought sulphur dyed always equalled black, silly me!

This is interesting. So overdyed garments always use sulphur as well…did not know this. I applaud IH for placing their environmental responsibilities as a priority. This makes me love the brand even more and proud to be contributing to an organization with its head on straight.

No, overdyeing can be done in lots of different ways.

One of them, and currently the most pleasing from an evolution point of view is sulphur based, but it is challenging environmentally, and the cost of using sulpur is getting prohibitive because cleaning up waste-product to make it environmentally kind, is increasing massively.

So we are looking at alternatives to using sulphur in all our dyeing techniques.

@Giles is there a reason that other sulphur dyed garments I own (looking at you RGT) have a distinct smell to them, whereas it's never been an issue with my IH gear. Do they undergo any additional treatment to alleviate this?

I do not know, I will try and find out - on the Shinkansen to Kojima at ATM....

I came across this article. Speaking on Indican and sustainability of the denim industry.

https://abcnews.go.com/amp/US/new-discovery-blue-jean-dyeing-denim-sustainability-study/story?id=107564309

One excerpt from the article…
“Researchers found that forming indigo directly in the yarn through the engineering of an enzyme called indican eliminates the requirement for reducing chemicals while still ending up as the color indigo.”

I’m clueless about this whole process but it leads me to believe the indigo color achieved through this process would not fade. As it would not be a “dye” in the sense of dye adhering to the fabric but rather the enzyme chemically changing the color of the fabric. Maybe someone in the know can elaborate.

If shooting millions of even hundreds of thousands of these garments out id see the possibility of worry. The cost of paying the government penalties to do it may be a good reason. Gotta find a way to keep those buttons oxidized though. So much better looking. I had the 507blod sent in error. Hated the fit/look but those buttons almost made me deal with it. Used the opportunity to cancel the 526blod just for the fact it wasn't sulphur dyed.
