OK, Jim. You wanted to see me about your textile design project.

That's right. I've been looking at how a range of natural dyes can be used to colour fabrics like cotton and wool.

Why did you choose that topic?

Well, I got a lot of useful ideas from the museum, you know, at that exhibition of textiles.

But I've always been interested in anything to do with colour.

Years ago, I went to a carpet shop with my parents when we were on holiday in Turkey, and I remember all the amazing colors.

They might not all have been natural dyes.

Maybe not, but for the project I decided to follow it up.

And I found a great book about a botanic garden in California that specialises in plants used for dyes.

  1. So, in your project, you had to include a practical investigation.

Yeah. At first I couldn't decide on my variables.

I was going to just look at one type of fibre for example, like cotton. . .

And see how different types of dyes affected it?

Yes. Then I decided to include others as well.

So I looked at cotton and wool and nylon.

With just one type of dye?

Various types, including some that weren't natural, for comparison. OK.

So, I did the experiments last week.

I used some ready-made natural dyes.

I found a website which supplied them, they came in just a few days.

But I also made some of my own.

That must have taken quite a bit of time.

Yes, I'd thought it'd just be a matter of a teaspoon or so of dye.

And actually that wasn't the case at all.

Like I was using one vegetable, beetroot, for a red dye.

And I had to chop up a whole pile of it.

So it all took longer than I'd expected.

One possibility is to use food colorings.

I did use one. That was a yellow dye, an artificial one. Tartrazine?

Yeah. I used it on cotton first. It came out a great colour.

But when I rinsed the material, the colour was just washed away.

I'd been going to try it out on nylon, but I abandoned that idea.

Were you worried about health issues?

I'd thought if it's a legal food colouring, it must be safe.

Well, it can occasionally cause allergic reactions, I believe.

So?what?natural?dyes?did?you?look?at?

Well,?one?was?turmeric.

The?colour's?great,?it's?a?really?strong?yellow.

It's?generally?used?in?dishes?like?curry.

It's?meant?to?be?quite?good?for?your?health?when?eaten.

But?you?might?find?it's?not?permanent?when?it's?used?as?a?dye-a?few?washes,?and?it's?gone.

Right,?I?used?beetroot?as?a?dye?for?wool.

When?I?chop?up?beetroot?to?eat?I?always?end?up?with?bright?red?hands.

But?the?wool?ended?up?just?a?sort?of?watery?cream?shade.

Disappointing.?There's?a?natural?dye?called?Tyrian?purple.?Have?you?heard?of?that?

Yes.?It?comes?from?a?shellfish,?and?it?was?worn?in?ancient?times.

But?only?by?important?people?as?it?was?rare.

I?didn't?use?it.?It?fell?out?of?use?centuries?ago,?though?one?researcher?managed?to?get?

hold?of some?recently.

But?that?shade?of?purple?can?be?produced?by?chemical?dyes?nowadays.

Did?you?use?any?black?dyes?

Logwood.?That?was?quite?complicated.

I?had?to?prepare?the?fabric?so?the?dye?would?take.

I?hope?you?were?careful?to?wear?gloves.

Yes.?I?know?the?danger?with?that?dye.

Good.?It?can?be?extremely?dangerous?if?it's?ingested.

Now,?presumably?you?had?a?look?at?an?insect-based?dye?

Like?cochineal,?for?example?

Yes.?I?didn't?actually?make?that,

I?didn't?have?time?to?start?crushing?up?insects?to?get?the?red?colour?and?anyway?

they're?not available?here.

But?I?managed?to?get?the?dye?quite?easily?from?a?website.?But?it?cost?a?fortune.

I?can?see?why?it's?generally?just?used?in?cooking,?and?in?small?quantities.

Yes,?it's?very?effective,?but?that's?precisely?why?it's?not?used?as?a?dye.

I?also?read?about?using?metal?oxide.

Apparently?you?can?allow?iron?to?rust?while?it's?in?contact?with?the?fabric,?and?that?

colours?it.

Yes,?that?works?well?for?dying?cotton.

But?you?have?to?be?careful?as?the?metal?can?actually?affect?the?fabric

and?so?you?can't?expect?to?get?a?lot?of?wear?out?of?fabrics?treated?in?this?way.

And?the?colours?are?quite?subtle,?not?everyone?likes?them.

Anyway,?it?looks?as?if?you've?done?a?lot?of?work. . .

OK, Jim. You wanted to see me about your textile design project.

好的,Jim。你想让我看看你的纺织品设计研究课题。

That's right. I've been looking at how a range of natural dyes can be used to colour fabrics like cotton and wool.

是的。我正在研究一系列的天然染料如何给像棉花和羊毛这种材料染色。

Why did you choose that topic?

你为什么选择这个课题呢?

Well, I got a lot of useful ideas from the museum, you know, at that exhibition of textiles.

恩,我从博物馆里汲取了很多有用的想法,你知道的,就在纺织品展那里。

But I've always been interested in anything to do with colour.

但是我一直对和颜色相关的一切都很感兴趣。

Years ago, I went to a carpet shop with my parents when we were on holiday in Turkey, and I remember all the amazing colors.

很多年以前,我和我父母去土耳其旅游的时候进了一家地毯商店,我仍然记得那些美妙的颜色。

They might not all have been natural dyes.

它们可能不完全都是自然染料染的。

Maybe not, but for the project I decided to follow it up.

可能不是,但是我想做一个延续这个的课题。

And I found a great book about a botanic garden in California that specialises in plants used for dyes.

我发现一本关于加利福尼亚植物园的很棒的书,专攻用作染料的植物。

  1. So, in your project, you had to include a practical investigation.

好的,所以在你的课题中,你得包括实际调查。

Yeah. At first I couldn't decide on my variables.

是的。刚开始我没法决定我的变量。

I was going to just look at one type of fibre for example, like cotton. . .

我就想先研究一种类型的纤维,比如说,棉花...

And see how different types of dyes affected it?

然后看看不同染料是如何影响它的?

Yes. Then I decided to include others as well.

对。然后我决定把其他的也包括进来。

So I looked at cotton and wool and nylon.

所以我研究了棉花、羊毛和尼龙。

With just one type of dye?

只是一种染料吗?

Various types, including some that weren't natural, for comparison. OK.

很多种,包括非自然的染料,用作对比。好的。

So, I did the experiments last week.

所以,我上周做了实验。

I used some ready-made natural dyes.

我用了一些现成的自然染料。

I found a website which supplied them, they came in just a few days.

我找到了一个提供这些材料的网站,几天就到了。

But I also made some of my own.

但是我自己也做了一些。

That must have taken quite a bit of time.

那肯定花了很多时间。

Yes, I'd thought it'd just be a matter of a teaspoon or so of dye.

是的,我本来觉得只需要一茶匙左右的染料。

And actually that wasn't the case at all.

后来发现完全不是这样。

Like I was using one vegetable, beetroot, for a red dye.

就像我在使用一种蔬菜,也就是甜菜根做红色燃料的时候。

And I had to chop up a whole pile of it.

我得切上一堆原材料。

So it all took longer than I'd expected.

所以比我预期花了更多的时间。

One possibility is to use food colorings.

有一种可能是使用食物染色。

I did use one. That was a yellow dye, an artificial one. Tartrazine?

我确实用了。那是一种黄色染料,人工的。酒石黄吗?

Yeah. I used it on cotton first. It came out a great colour.

是的,我刚开始在棉花上用了它。颜色很好看。

But when I rinsed the material, the colour was just washed away.

但是当我漂洗材料的时候,颜色全被洗掉了。

I'd been going to try it out on nylon, but I abandoned that idea.

我本来想在尼龙上试一下,但是我放弃了那个想法。

Were you worried about health issues?

你担心健康问题吗?

I'd thought if it's a legal food colouring, it must be safe.

我觉得如果它是合法的食物染色剂的话,应该是安全的。

Well, it can occasionally cause allergic reactions, I believe.

恩,但是它有时候会导致一些过敏反应。

So?what?natural?dyes?did?you?look?at?

所以你研究了什么自然染料呢?

Well,?one?was?turmeric.

哦,一个是姜黄。

The?colour's?great,?it's?a?really?strong?yellow.

那个颜色很棒,是非常明亮的黄色。

It's?generally?used?in?dishes?like?curry.

它一般会在咖喱这种菜里面用到。

It's?meant?to?be?quite?good?for?your?health?when?eaten.

所以吃起来对身体健康很好。

But?you?might?find?it's?not?permanent?when?it's?used?as?a?dye-a?few?washes,?and?it's?gone.

但是你可能发现如果作为染料的话,它不够持久——洗几次就全都掉色了。

Right,?I?used?beetroot?as?a?dye?for?wool.

对,我用甜菜根给羊毛染色了。

When?I?chop?up?beetroot?to?eat?I?always?end?up?with?bright?red?hands.

每次切甜菜根吃的时候,我的手都会是红红的。

But?the?wool?ended?up?just?a?sort?of?watery?cream?shade.

但是羊毛只是有点水黄色的阴影。

Disappointing.?There's?a?natural?dye?called?Tyrian?purple.?Have?you?heard?of?that?

太令人失望了。有一种叫做泰尔红紫的天然染料。你听说过吗?

Yes.?It?comes?from?a?shellfish,?and?it?was?worn?in?ancient?times.

是的,它取自于一种贝类,古代的时候有人穿。

But?only?by?important?people?as?it?was?rare.

但是只有那些重要人物才会穿,因为它很珍稀。

I?didn't?use?it.?It?fell?out?of?use?centuries?ago,?though?one?researcher?managed?to?get?

hold?of some?recently.

我没有用它。几个世纪之前它就不再使用了,尽管有一个研究人员最近想做出一些。

But?that?shade?of?purple?can?be?produced?by?chemical?dyes?nowadays.

但是那种紫色现在可以通过化学染剂做出来。

Did?you?use?any?black?dyes?

你用了黑色染料吗?

Logwood.?That?was?quite?complicated.

洋苏木。那真的很复杂。

I?had?to?prepare?the?fabric?so?the?dye?would?take.

我得准备染料能够染上的材料。

I?hope?you?were?careful?to?wear?gloves.

我希望你带了手套。

Yes.?I?know?the?danger?with?that?dye.

是的,我知道那种染料存在危险。

Good.?It?can?be?extremely?dangerous?if?it's?ingested.

好的。如果不小心食用的话,它真的超级危险。

Now,?presumably?you?had?a?look?at?an?insect-based?dye?

现在,你大概已经研究过了昆虫染料了吧?

Like?cochineal,?for?example?

比如说,胭脂虫红?

Yes.?I?didn't?actually?make?that,

是的。事实上我并没有做,

I?didn't?have?time?to?start?crushing?up?insects?to?get?the?red?colour?and?anyway?they're?not available?here.

因为我没有时间碾压昆虫来提取红色,而且这里没有胭脂虫。

But?I?managed?to?get?the?dye?quite?easily?from?a?website.?But?it?cost?a?fortune.

但是我能从一个网站上得到这种染料。但是很贵。

I?can?see?why?it's?generally?just?used?in?cooking,?and?in?small?quantities.

我知道它为什么通常只用于烹饪了,而且量很小。

Yes,?it's?very?effective,?but?that's?precisely?why?it's?not?used?as?a?dye.

是的,它非常有效,但是那可能是它没有用做一种染料的原因。

I?also?read?about?using?metal?oxide.

我还读了一些有关使用金属氧化物的书。

Apparently?you?can?allow?iron?to?rust?while?it's?in?contact?with?the?fabric,?and?that?

colours?it.

当铁和织物接触的时候,你可以让铁生锈,就会给织物上色。

Yes,?that?works?well?for?dying?cotton.

是的,这样给棉花染色挺好的。

But?you?have?to?be?careful?as?the?metal?can?actually?affect?the?fabric

但是你得很小心,因为金属会影响织物,

and?so?you?can't?expect?to?get?a?lot?of?wear?out?of?fabrics?treated?in?this?way.

所以你做很多使用这种方法制作的织物成衣。

And?the?colours?are?quite?subtle,?not?everyone?likes?them.

而且颜色比较淡,不是所有人都喜欢。

Anyway,?it?looks?as?if?you've?done?a?lot?of?work. . .

但是,能看出来你做了很多工作...
