Undocumented Weaving and Dyeing Techniques in SiLaen

The weaving tradition in the area Southeast of Lake Toba was once unique and rich. Various types of traditional cloths (ulos) were made here that are not found in other Batak areas, such as the Ragi Harangan and the Sangkarsangkar, remarkable for their ikat patterning and deep, rich dyes. The weaving tradition in this region has never been well studied. Weavers there resisted commercialization and commodification of their work longer than in other regions, but in the 1980s and 1990s this resistance was finally broken. Many old pieces appeared on the tourist/collector market and the tradition lost its vibrancy.  

 

In 2016, when I was trying to learn more about the use of Morinda citrifolia, a tree that yields red dye, known amongst the Batak as bangkudu, I drove through SiLaen, about a half hour away from Porsea at the S.E corner of Lake Toba. When Batak weavers still relied on natural dyes, bangkudu was still a common tree found in every village. Now it is rare because weavers use commercial, synthetic red dye that they purchase on the market. A bangkudu tree in SiLaen caught my attention, therefore, when I drove past. I wanted to know if there was a weaver in the vicinity and so I knocked on the door of a house near the tree and I was invited in.

 

My host was an elderly weaver, probably in her 70s, who had some ulos for sale. I was in luck because when I enquired, it turned out that her grandmother had worked with natural dyes and she had observed her grandmother until she was 18 years of age. I asked the elderly weaver some questions. I couldn’t understand her answers in their entirety. Nevertheless, I was able to take a few notes during our brief stay. I believe that the techniques that she described are unique to her region. 

 

She remembered that yarn had been locally spun using the spinning wheel (sorha) in 1942. Cotton (kapas) was planted and after 6 months the cotton bolls could be harvested.  It hurt, she said, “Hansit ma hape”, and my sense was that she was referring to the hard labour involved in making yarn.

 

Then the yarn was dyed. She mentioned the distinction between blue yarn, dyed solely in an indigo solution, and black yarn (na itom) made using the sigira technique. I was familiar with this from all over the Batak region. She said that the yarn (1 kumpal, a skein-like measure) was first dyed in an indigo solution (mansop) for three days, 6 hours at a time each day. This turned the yarn blue. When the indigo process was finished and the yarn was dry, the next stage could begin. This was when they put the blue yarn into a red dye (bangkudu) bath. The use of Morinda citrifolia as part of the sigira process was new to me. In other regions, the sigira process involves putting the indigo-dyed yarn into black mud where the iron content of the mud interacts with the indigo, turning the yarn black.

 

There were no restrictions on who could fetch the bangkudu root; it could be harvested by both men and women. The dye material was dried and then brought to a boil (together with other ingredients), but not boiled for long, at the edge of the river. The weaver said that a hole was dug in the ground beside the river and the liquid bangkudu dye was poured into the hole. It was not clear to me whether the earth of the hole was sufficient to make the desired chemical reaction, or whether additional earth, which she said was fetched from the foot of the mountains, was needed. Water with high iron content was added to the mixture (aek sibaungbaung: na tasihan, tasik, aek na karatan) meaning rusty water, or water with iron content. One would not wash clothes in such water, the weaver said, or they would turn yellow. ‘Rusty water’ is an ingredient when dyeing with Morinda citrifolia elsewhere as well. The weaver said that this combination of red and blue was used for various ulos design types and she gave the design types called Ragi Pangko and Antahantak (fig 2) as examples. (Legacy in cloth, Fig Cat 4.4 p. and Fig Cat 5.6 p. 304 – 305).

 

The information given (or that I managed to understand) was limited, but it gave me pause to reflect on her tradition and of course it raised several additional questions.  

 

1.     The weaver did not show me an example of the result from dyeing yarn with both blue and red dyes, and the colour that it yields is not clear to me. However, reviewing the cloths from the weaver’s area, I see a range from deep blue with a reddish-purple sheen, to a deep chocolate red. My awe for the prowess of the dyers explodes. The dyers knew how to create quite a variety of deep colours.  Evident in fig. 1 is the white of undyed yarn, the deep chocolate-red colour, and also bright red ikat. One question that comes up is whether the deep chocolate-red colour results just from bangkudu combined with the iron-rich mud and water (or perhaps tanin), or whether there is also indigo dye involved.  In fig. 2 a weaver in Porsea is holding up a lighter-coloured cloth of which the sides have a red/purple hue. Could this be the result of indigo dyeing with sigira that includes bangkudu? By combining blue and red by dyeing the yarn successively in these two colours followed by the mud bath, could the weaver achieve a whole gradient of colours along a blue – red – black spectrum? Deeper colours are produced by dipping the yarn in the dye over and over again. However, the elderly weaver told me that the dip in sigira was done only once. The proof would be in experimenting with the dye baths, or listening to elderly weavers – of which few, anymore, know the dyeing tradition. None practise it anymore.

2.     Special, in this region, is red-dyed ikat patterning in indigo-dyed yarn. I don’t think that the weaver was describing how this was done because she didn’t mention ikat – except to say in passing that she had taught all of her daughters how to make ikat. To yield this result, the yarn would be dyed with indigo after the yarn was wrapped with ties to resist the dye. When the ties were removed and the yarn was dipped in the red or bangkudu dye, the spared bits would turn red (fig. 2) (see also Legacy in cloth, p. 305 Fig. Cat 5.6b). The question that arises here is whether the weaver would submerge even the blue parts of the yarn in the red dye, thus dyeing it both blue and red, or whether she would bind off the blue part? Given the colour variation in old cloths, they may have practised both strategies.

 

3.     How important and prevalent was the use of the iron-rich water when dyeing in this region? As the weaver mentioned, it would turn clothing yellow. Certainly, many red cloths from this region have a deep maroon-chocolate colour (fig. ) e.g. Legacy in cloth, p. 268, 278). This could be from tanins, but also from the iron in the water.

I became very excited when the weaver remembered that a resist dye technique had been followed to make the ‘white ends of a cloth’. This is evident in fig. 3. It was also sometimes practised when making the most extraordinary cloth from the region, the Pinunsaan (Legacy in cloth p. 363), but also other weavings with white ends, such as the Simpar (p. 300 Legacy in cloth). However, I had never met a weaver who was familiar with the process. This weaver in SiLaen was able to let me know that the end (of the warp, not the whole cloth) was dibungkus or tied off using part (leaves?) of the banana tree. The reed-like sungkit could be used as well. It is easier just to sew a white piece of ulos onto the middle section to produce white ends in the cloth, and this is done in 'morden times'. It is unclear whether the resist dye technique was always practised in the past to achieve this design result. This would be consistent with the deep Batak conviction that the warp should not be broken, but rather continuous.

 

The weaver also remembered the use of hori, a nettle plant that Batak weavers used to make a coarse fabric. I had never been able to find first-hand information about the use of this fiber. The fibres, if anything like the nettles in the Northern hemisphere, were probably quite long. She mentioned that they were knotted (dipuduni) probably end to end to produce a long yarn, and then wound up using the spinning wheel. To my knowledge there is only one hori in a museum collection, a coarse and simple cloth.
