steps to the finish line 着物の段階

Since I last posted pictures in my post Making a Kimono..., I have gone through several important stages of the process: nori-oki (applying resist paste), ji-ire (applying pre-dye sizing), fuse-nori (covering paste) and ji-zome (background dyeing). Here I'll try and briefly explain these steps.

着物を制作なんて!を書いて以来、いくつの重要な段階もやりました。それは、糊置き、地入れ、伏せ糊と地染めです。ここで写真で説明しようと思っています。

*Nori-oki 乗り置き
literally means the putting on of paste. In all my previous work, I have used the traditional form of nori that is a combination of mochiko rice flour and komon-nuka rice bran. Traditional nori is soluable in water and dries to a stiff resist. In humid summer months, the dried nori remains leathery but in winter it's water content to dry up and it ends up cracked like an egg shell (not good!). Being winter this time, and for it's water resistance (essential to the background dyeing part of the process) I used gomu-nori, a rubber paste that has a blue colour added to it for visibility. It is much more sticky and viscous than standard nori and smells like paint (unfortunate) but on the plus side, it is nice and flexible when it's dry and it doesn't wash out in water which means it can be used in clever combination underneath standard nori to achieve layers of dye.

青花で描いた線に沿ってゴム糊を置いていきます。この場合、渋紙で作られた筒ではばく、セロファンで作った筒を使います。
applying rubber paste along the lines traced with aobana (water soluble ink) onto the fabric previously.  in the case of  rubber nori, you can use a cellophane cone (much like cake decorating), and throw it out once empty and start on a new one. Wasteful but better than getting this sticky rubber all over your fingers and nice metal tipped paper cone.
糊を置くと、ただ青花に沿っていくということじゃなくて、よりいい作品を作るために改めて見て、あちこちにちょっと変更することがいいと言われています。
They say that when applying the resist paste, you ought to be improving upon your design as  you go. That is, rather than following the traced lines passively, see the design afresh and make any changes you see fit.
前の作品は昔からあった小紋糠と餅粉で作られた糊を使いましたが、冬にはこの糊が割りやすいし、地染めのことを考えたら、今回はゴム糊のほうが適切でした。買ったゴム糊は「群青入ゴム糊」で、見えやすいように青色が入れています。ゴム糊がペンキの匂いがするけど、柔らかくて置きやすいし、乾いたらまだ柔軟です。水で解けないので、普通の糊とともに置けば賢い染め方もできます。

*Ji-ire 地入れ
Ji-ire is the term for pre-sizing the fabric before dyeing. Japanese textiles traditionally use milk extracted from soybeans and a thickener in the form of funori-seaweed. This application of sizing helps the dye 'grip' the fabric evenly and prevents dyed edges from bleeding. The ji-ire liquid is applied to the back side of the entire length of fabric quickly and in one go, keeping the brush moving and working down the fabric to ensure an even application. I made a 2 minute video of this process when I was about 70% of the way down one of my lengths of fabric. My wrist was starting to get sore by this point!  You can see it is tricky to work around the bamboo shinshi that are keeping the fabric stretched taut.

*Fuse-nori 伏せ糊
Having applied my design areas using the rubber resist, I now want to be able to dye the background colour. To do this, I need to mask all those precious birds and plants so they remain white, to be dyed later. This is where the rubber resist proves it's worth. I go back and apply a masking layer of normal resist paste over my design areas, this time using the normal paper cone with a metal tip. To help this resist dye, you sprinkle a layer of fine sawdust on top of the wet paste. When it's dry, it feels a little like sandpaper.

渋紙の筒で普通の糊をゴム糊の上に置きます。地染めの色に染めたくない部分を守るというわけです。  protecting the parts of the design I don't want to dye yet by applying normal resist paste on top of the rubber resist. 
先がねを外したら、広いところを早く伏せられます。taking the metal tip off to cover larger areas more quickly.
乾いていない糊にひき粉を撒きます。sprinkling fine sawdust over the wet paste will give it strength.
生地を全体的に紫に染めたいけど、ゴム糊で描いた部分を染めたくないですね。ゴム糊で描いてある鳥や植物を白いのままに守るために、ゴム糊の上に普通の糊を置きます。これは伏せ糊といいます。紫を染めたら、普通の糊を洗って取ったら、ゴム糊や白い模様の部分が残っています。賢いでしょう!糊の防染力を上げるために伏せ糊が乾かない内に、ひき粉をまきます。乾いたらちょっとヤスリに似ています。

*Ji-zome 地染め
Finally the nerve racking step of dyeing the base fabric colour. This makes you sweat for two reasons. 1. You'll be physically sweating by the end because you need to dye all 17 metres in one go so that your colour application is even and the fabric all dries in the same temperature conditions etc. 2. You will sweat it out mentally because you're hoping that your fuse-nori is doing it's job resisting the dye and that you aren't leaving any (too many) irregular areas in your dyeing. 
The dye is applied in the same way as the sizing, but with a more (expensive!) absorbent brush made from deer hair. You need to be applying just enough dye so that you're not dry-brushing the fabric but certainly not flooding it either. 

 紫!今回も酸性染料で染めました。紫専用の刷毛ですねmmm, purple! using the 'purple-only' brush, made from deer hair. This is acid dyestuff. 

染めた時は焦っていたので糊が置いた状態の写真が取りませんでした!この写真では普通の糊が洗い取った状態で、ゴム糊の線と白い模様の部分が残っています。よっしゃ!I was busy in the moment of dyeing, so I don't have a picture of the dyed lengths with the paste still attached. Here, you see the fabric after the normal paste has been washed off and the rubber resist lines remain, along with my white design areas. yay!
紫の地染めした後の生地です!これで次の段階(色さし)の準備ができました。(実はこれを撮ったときはもう少しだけ色さしを始まりましたけどね)detail of the fabric with the background dyed,  ready for the next stage: dyeing the patterned areas! (actually  I had already started here, just a little bit on the grass seed pods )
地染めの段階に着くと色んな理由で汗が出ます!一つは、17メートルの生地を一気に染めないといけないので、肉体的に汗をかきますよ!もう一つは、精神的に緊張になって、汗をかきます!糊が本当に防染しているかどうかの心配もあるし、むらがないように綺麗に染めないといけないから緊張してきます。地入れと同じようにひきますが、今回はもっと高い鹿の毛で作られた刷毛で染めます。

And so now I'm off to add colour to my pattern and bring it all to life!!
さあ、このあとは模様に活気を与えるように、色さしををやります!

  1. How do you remove the rubber lines? Do you put any resist over the dyed background, to keep new dyes from seeping out?

    It's so beautiful with that dark background! Is the bird holding a dragonfly?

    Looking forward to seeing the next steps :)

    1. Hi Mandi,
      The rubber resist is soluble in a volalitile oil solution for which reason most people entrust their work to a business that does this removal. I imagine the fabric will just be soaked in some liquid chemical. Actually the chemical nature if this whole process is playing on mind and it has got me thinking about my next pieces and what choices I will make.

      The background stays as is and you just need to be careful not to drip dye or anything on it but the rubber resist lines will keep the new dye application from seeping, much like silk painting.

      Good spotting! Yes, these birds eat bees and moths and other insects :)

  2. Melinda, that is absolutely beautiful. It's fascinating to hear the way the soy milk is used in this particular technique - as well as the rubber resist. Living in a cold North America climate I know what you mean about cracking dry paste! I look forward to your results!

  3. thanks Kit! Australia is unkind to nori too! I'll be posting some dyeing progress photos soon :)
