Amazing Japanese kimono dye it black Process! Technology to pursue the world's best black color! 

As a tie dyer, i'm very familiar with some of the processes used here. For instance, gluing on the buttons creates a resist so that dye does not penetrate where the glue was. The dyes themselves look to be a commercial, cellulose fibre-reactive dye, something like Drimarene K, Procion MX or Cibacron F dyes (i'm thinking Drimarene K), and have sodium carbonate (soda ash, also used as a washing booster) as a fixative. Note that when you're overdying like what happens later in the video, the dyes above only work on cellulose fibres, like cotton, silk, rayon, hemp or linen. Even then, the previous colours of the garment will play a role and possibly show through to a small extent. Where possible, its best to try and lighten any previous colours using a dye removing agent first, though this can be time consuming. Do NOT use bleach! Bleach attacks cellulose fibres, causing them to decay and break. In short, that shirt you tried to lighten will go a weird yellow colour then tear apart. When referring to bleach in this video, bleach is not being used - a dye removing paste that removes colour under heat, is being used.

I like the re-dye secondhand clothes idea. ❤

Processo extraordinário !!!!

The skills and attention to detail is extraordinary

I love the fact he does old clothes with the same black dye, seeing the garments that were reds or gold coming out black giving them new life is fantastic. That’s is the best black I have ever seen would love to just have some of the fabric to make something for myself. I have bought black fabric in the past but that black was really black compared to what I have. To make mine look as good I have to add splashes of colour and this fools the eye into thinking the black is darker.

I am SO impressed by this. Absolutely beautiful

WOW! That is one very hard working gentleman 👏👏👏👏🇬🇧

오랜 시간에 걸쳐 한 분야에 전문가라고 해도 이상하지 않을 만큼 노력해오신 분들께 정말 존경한다는 말씀 드리고 싶어요. 어떤 한가지 일을 지속적으로 한다는 건 정말 어려운 일이잖아요. 물론 내 생계를 위해 한다는 것이 이유가 될 수는 있지만 그럼에도 불구하고 자신이 하는 일에 매 순간 최선을 다해 달려오신게 정말 대단하신 것 같아요.
