What Do You Mean, "Soak It"?

One thing that often happens, especially in the uncontrollable chaos of group tie-dyeing at YMCA family camp, is that someone will carefully tie his or her piece and start dyeing it, then hear me telling someone else to go soak their tied piece in the bucket of soda ash solution.

"What do you mean, 'soak it'? I didn't do that..."

Thus begins a process I call a "rescue". The Procion fiber reactive dyes I use need the soda ash to make the color bond to the fibers in the fabric, making the colors permanent. What I usually do for these cases is place the dyed piece in an empty bucket and pour some of the soda ash solution over it (one year a camper dumped her blue piece in the main soda ash bucket on top of other pieces that were soaking. They all got dyed pale blue!) and let it soak. I then have the owner put more dye on to counteract the small amount of washing out that happens when we soak it.

The Experiment

This rescue process seems to work well enough, but I was curious as to how much of a difference it really made. So while I was there at camp, I tried an experiment. I tied three identical prewashed cotton bandanas the same way. I soaked one in soda ash, then I dyed all three the same way. The other two were dyed without soda ash. I took one of those two and did a "rescue", pouring soda ash over it and then adding more dye. I then let them sit overnight and washed as usual. So my three bandanas are the "control" (usual process), the "no soda ash", and the "rescue".

One initial observation: I generally dislike dyeing dry fabric, with or without soda ash (some people advocate soaking tied items in soda ash, drying them out and then dyeing). Even if the item is prewashed, the dye often beads up, runs off in unwanted directions, or pools up. Once it does soak in, it tends to spread unevenly. With the soda-ash-soaked bandana, the dye goes in smoothly and spreads more evenly, while I have to pretty much force the dye into the two dry bandanas.

The Results

There was a distinct difference among the three finished bandanas after I washed them out, though not quite as much difference as I expected. In the following picture, the "control" (usual soda ash soaking) sample is on the left, the "rescue" is on the right, and the one in the middle has no soda ash at all. The middle sample is definitely more dull and faded-looking than the other two, especially for the dark cobalt blue triangles on the sides. They are at least a shade lighter than their counterparts on the other bandanas. The "rescue" sample has more vibrant colors than the untreated sample, though it lacks the definition of the "control" sample.


I think part of the difference in pattern definition between the rescue and control samples may be due to dyeing on dry fabric--the dye absorption and spreading properties are different. Also, when the dyed "rescue" sample is soaked in soda ash after dyeing, the soda ash solution may be spreading the dye, blurring the whiter areas you see in the "control" sample. The re-dyeing after soaking may also aggravate the blurring.

Here is another picture where you can see the differences more directly (click on the picture to see a larger version).


Conclusions

It's clear that the best process for nice sharp tie-dye is to soak the item in soda ash before dyeing it. However, given that mistakes often happen, I think doing the "rescue" process is preferable over just going without the soda ash, so I'll continue to recommend that as necessary.

One further thing I want to do is to wash all three bandanas a couple more times. I know from experience that I won't see much change in the colors for the two that had soda ash, but I wonder if the untreated bandana will show visible washing out of the colors. I'll be doing a lot of
tie-dye washing in the next week or so, so I'll put an update out later.

Once again, my dog Lacey, knowing how fabulous she looks on tie-dye, decided to help me out when she saw me getting ready to take tie-dye pictures! That's the "rescue" sample.

Tie-Dye Group Dynamics

Over Memorial Day weekend, I went to YMCA Camp Jones Gulch Family Camp out under the California redwoods. I'm not much of a hiker, and I hate riding horses (the knees are just not flexible enough anymore), so I usually spend much of my weekend hanging out in the crafts area. The last few times I've gone to family camp, I've actually volunteered and run a tie-dye activity there, and I did it this time too.

I have done large groups several times, but there are different dynamics depending on the group.

The Whole First Grade, for the Fifth Year

When I work with my first graders, I'm working with a relatively homogeneous group. I have volunteer parent helpers and the teachers to keep things under control. It's pretty much a class project like any other, and the kids are expected to pay attention to the lecture and then do what they are supposed to. The kids get to make choices about how they want to fold their own shirt (which of three folding patterns) and what colors they want to use, but they all work pretty much in lockstep. They all fold at the same time, and they all dye at the same time (a class at a time, 5 classes). The results are uniformly decent-to-very-good (and you can tell what pattern they were trying to make), since everyone gets help. The kids love it, especially since they get to keep the finished shirts.

And Off to Family Camp

When I tie-dye at family camp, things are quite different. The group is more diverse in age and ability (kids of all ages, with or without their parents there, a few grandparents). The tying and dyeing are available all day Saturday, and people wander in when they want to, so sometimes it's a rush, and sometimes it's a trickle. I don't really know how many people are going to show up, since they might only come if they have time between other activities and aren't too tired. I think I had around a hundred people wander through, but I don't know for sure.

At family camp, I'm the only tie-dye "expert", and I have one or two counselors dedicated to working on this activity. We can't provide nearly as much help as we do for the first graders. Many people don't want help anyhow--they just want to do their own thing and go wild (such as the nine-or-ten-year-old boy who dyed his shirt by mopping up the puddles of dye left on the table by previous participants--in an example of how unfair the world is, his shirt came out quite nicely!). Many people are making things up as they go along. Some people achieve bold geometric patterns, while others go for random splotches of color. The results vary wildly.

It's Art and More

Group tie-dye is a very popular activity. In the first grade classes, it's a chance to make art, to make a mess, and to make a shirt of your own. At family camp, it's all of those things and more. The process can be a family bonding activity, and making matching shirts, bandanas, and so on helps bond families further when they all wear and show off the matching clothes.

For some, it's a chance to relive fond memories of doing camp or school activities they did when they were kids themselves, or a chance to catch up on fun they missed when "everyone else was doing it".

Cool.
