藍建4種と染色性の試験  making 4 indigo vats and trials of dye-affinity

1月 すくも藍100L建(すくも藍6kg、小麦麩50g、灰汁90L)、消石灰(pH調整)

January, making Sukumo(fermented dry leaves,  Polygonum tincturum) 100L vat

(6kg Sukumo, 50g wheat bran, 90L lye of oak ash,  a little slake lime for controlling pH)

2月 琉球藍100L建(琉球藍ペースト8kg、小麦麩50g、浸漬液10L、灰汁80L)

消石灰(pH調整)

February, making Ryukyu-ai(indigo paste, extracted and oxidised with slake lime, Strobilanthes cusia) 100L vat, (8kg of indigo paste, 50g of bran, 10L of soaking solution,  80L of lye with oak ash, a little slake lime for controlling pH)

3月 インド藍靛建100L(インド藍靛600g、小麦麩50g、インドアイ葉200gのペースト、灰汁90L、消石灰(pH調整)

March, making Indigo cakes(indigo cube, extracted and oxidised,  Indigofera tinctoria) 100L vat, (600g of indigo cakes, 50g of bran, paste with 200g of Indigofera leaves, 90L of lye of oak ash, a little slake lime for controlling pH)

4月 ウォードすくも建50L(ウォードすくも建20Lの嵩上げ:ウォードボール500g、インド藍靛130g、小麦麩25g、灰汁30L、消石灰(pH調整)

April, increased a couched woad(fermented woad ball,  Isatis tinctoria) 50L vat,(add 500g of woad ball, 130g of indigo cakes, 25g of bran, 30L of lye of oak ash into 20L couched woad vat, a little slake lime for controlling pH)

5月 それぞれの藍建液の染色性をあげる試み:発酵状態を観ながら、微生物の活性で低下したpHを徐々に上げ、綿糸、麻糸、羊毛原毛、羊毛糸各1kgを100Lの液で藍染、酸化を繰り返しながら2時間かけて藍染し、液の活性と染糸の濃度を比較した。

May, the trial for improving dye-affinity of each vat : looking fermentation state, gently increasing pH became down by microbe activity, then dyed each 1kg of cotton, linen, raw wool and wool yarn in each 100L vat for 2 hours dyeing and oxidising yarn and fibre, made a comparison with active of vat and colour value of dyed yarn.
