  • Ow...I think I need some help with my laundry.

    唉喲...誰來教教我怎麼洗衣服啊

  • Hey there, washed and left out to dry. Trace here rockin' some duds on DNews. You might think

    哈囉,各位深受洗衣困擾的民眾們。我是 Trace,在 Dnews 上介紹有關衣服的知識。你可能會

  • science is something only done in labs, but every week or so chances are you suspend organic

    認為科學是在實驗室裡才會發生的,但其實你每個禮拜都會將有機纖維

  • and synthetic fibers in a solution of water, enzymes, surfactants, and detergents to confine

    與人造纖維泡在充滿酵素、介面活性劑、清潔劑水溶液裡,以包覆

  • particulates and relax molecular bonds. In layman's terms: you do laundry, and when you

    微粒與分解分子鍵結。用俗話說:洗衣服。而當你

  • think about it, you're really doing controlled chemistry! Unfortunately, we don't all do

    仔細想想,你會發現你其實是在做可控的化學實驗!不幸的是,我們不會

  • this at-home science in the same way, which is why when doing laundry, we've all messed

    用一樣的方式來做這個家庭式實驗,這也是為什麼我們在洗衣服時,常常毀了

  • up our favorite sweater or shrunk a pair of pants. But why do all of these things shrink at all?

    我們最喜歡的毛衣或讓某件褲子縮水。但為什麼衣服會縮水呢?

  • What's going on there?

    到底發生了什麼事?

  • So, firstly, there are a couple kinds of fibers used to make clothing: synthetic and natural.

    第一,衣服有許多不同的原料,像是人工合成或是天然的原料

  • In general, synthetics are man-made polymers like polyester, Kevlar, or acrylic.

    大致上來說,人工合成原料包括人工聚合物,像是聚脂纖維,防彈纖維,或壓克力

  • Their fibers are strings of petroleum-based chemical chains. Synthetics made from petroleum

    這些原料的纖維是由一串串石油提煉出的化學鍵結所組成。而這些從石油提煉出的人工合成原料

  • products don't typically shrink in laundry because the washer and dryer do not get hot

    通常不會因為洗衣服而縮水,因為洗衣機和烘乾機的溫度不會讓

  • enough to mess with their molecular structure or anything else. So, let's ignore those.

    破壞它們的分子結構,所以我們可以先不討論這些產品

  • Natural fibers, on the other hand, they come from animals and plants. The fibers of cotton,

    反之,天然的纖維是從動物和植物身上取得的。而像是棉花、

  • wool or silk are naturally curly and tangled. So when you want to weave these threads into

    羊毛、蠺絲這些纖維通常是捲曲糾結在一起的。所以如果你想要把這些材料縫製成

  • fabrics, you have to stretch then, and to pull them out to make them straight. But if given the opportunity

    布料,你會需要將它們拉直、伸展,讓纖維變成直的。但如果有機會,

  • to return to their natural curly state? They will. And scientists have discovered all that heat

    這些天然的布料還是會想變成以前的捲曲樣子。而科學家發現洗衣服時的

  • and mechanical energy in laundry let them do just that, in a process they call, funnily enough,

    溫度與化學成分就是使它們變回原狀的主因。而這也被稱之為,蠻好笑的,

  • Shrinkage.

    縮水

  • There are three kinds of shrinkage: Relaxation, Felting, and Consolidation.

    有三種不同的縮水類型:鬆弛類,沾黏類,與結塊類

  • Relaxing is the immediate release of that stretching and pulling tension left behind

    鬆弛類縮水是指壓力突然地被釋放

  • from the straightening of the natural fibers and manufacturing. That tension exists on a molecular level,

    而這壓力是指製造纖維時,那些拉直與伸展過程所殘餘的力量。這些壓力藏在分子與分子之間,

  • and is leftover from that process. When tepid or warm water is added to the natural fabric,

    是製造過程中所剩下來壓力。當微溫或溫水接觸到這些天然布料時,

  • the warmth will let the fabric swell, reducing the size by about 1 percent.

    水的溫度會讓布料膨脹,並讓布料的體積縮小約1%。

  • Not too shabby.

    還算不錯啦

  • Felting shrinkage is when the fibers themselves actually get shorter. If you magnify wool

    沾黏類縮水則是指纖維本身真的縮小了。如果你把羊毛用

  • in an electron microscope, it's made of tiny scales, just like human hair. According to

    電子顯微鏡觀測,會發現其實羊毛是由許多鱗片構成的,就像是人的頭髮一樣。而根據

  • a paper in the Textile Research Journal, the heat from the washer can expand these scales

    Textile Research Journal的一份報告指出,洗衣機的溫度會讓那些鱗片擴張,

  • letting water get in between them. Water is slippery, so it reduces the coefficient of friction,

    並讓水分進入鱗片之間。而水分會降低摩擦力

  • and those scales then slide together, contracting rootward, like a retracting car or radio antenna! Super cool!

    讓鱗片滑進另一鱗片裡面,往底部收縮,就像是把汽車或收音機天線收起來一樣!超酷的!

  • The third type is Consolidation shrinkage, and it happens in the laundry process itself.

    第三種縮水類型是結塊類縮水,而這與洗衣服的過程有關

  • The mechanical bouncing action of your washer and drier beats up the fibers, causing them

    洗衣機與烘乾機的機械式洗滌方法會擠壓纖維,讓纖維

  • to curl back up again.

    捲成像之前一樣的程度

  • A 2002 study in The Research Journal of Association of Universities for Textiles. found the structure

    一份2002年來自The Research Journal of Association of Universities for Textiles的研究發現纖維的

  • of the fabric can affect shrinkage too. Denim jeans are tightly-woven cotton so they

    結構也會影響縮水程度。像是牛仔褲就是由結構縝密的棉質布料織成,所以它們只會

  • shrink a little, but sweaters, they're mostly air! So they can shrink by as much as 30 percent according

    縮水一點點,但是像毛衣纖維之間根本是空氣!所以他們最多可以縮小30%,根據

  • to Popular Science.

    Popular Science的研究顯示

  • Even the natural moisture content of the fibers themselves can affect the shrinkage: cotton has

    而纖維本身的溼氣多寡也能讓衣服縮水:正常來說,棉的溼氣

  • about 5 percent, and wool has about 17 percent, so over-drying can will inevitably cause clothing

    約佔5%,羊毛的溼氣則占約17%,所以過度的烘乾會無可避免地讓衣服

  • to change shape.

    的形狀改變

  • In World War II, Nazi scientists added plastics to wool to fill in the spaces and solidify

    在二次世界大戰時,納粹科學家把塑膠加入羊毛裡,以填補空隙與鞏固

  • the fibers. Today this continues with manufacturers weaving in non-shrinking

    羊毛纖維結構,而現今仍沿用此觀念,紡織廠會在衣物縫入不會縮水的

  • synthetics, and chemists inventing new anti-shrinking agents to cover natural fibers and keep them

    人工合成物,而科學家則發明了許多抗縮水的清潔劑,覆蓋住天然纖維,讓它們不要

  • from curling up. More researches obviously needed.

    又捲起來。這方面仍需更多研究

  • Look, scientists who did write these papers on shrinkage were quick to point out: everyone does laundry

    事實是,那些做了許多有關縮水研究的科學家都有個共識:大家洗衣服的方法

  • differently. Water temperature, amount of time, detergent, clothing fibers, and even

    都不一樣。而水溫,洗滌時間長短,洗衣粉,衣物纖維種類,甚至是

  • machine manufacturer can all add variables to to this at-home science project

    洗衣機的製造商都能為這個居家實驗添增許多變數

  • The best way to love your clothes is to remember that, one, the instructions on the tag is there for a reason

    最好能愛惜你的衣物的方法就是:第一,遵守標籤上的指示

  • the people who made the clothes know how to clean it. And when in doubt don't

    製作這件衣服的人知道如何清洗它,但如果還是不確定如何清洗,

  • add heat and mechanical energy. Use cold water and avoid the dryer. And two: remember that

    記得不要用熱水洗衣服,並改用手洗。盡量用冷水洗滌,並不要用烘乾機。第二點:記得

  • natural fiber clothing is made from the parts of living things! Living things aren't supposed

    由天然纖維製成的衣物是從活生生的動植物身上取下來的!這些生物並不會

  • to last forever. And that's actually kind of okay.

    永遠存在在世上。這是可以理解的

  • Skinny jeans, sweaters, tiny t-shirtswhy am I reminded of hipsters?

    窄版褲,毛衣,緊身T恤... 為什麼這讓我想起文青啊?

  • Oh, because they're all the same! At least, that's what this mathematician discovered! So I did a whole video about it.

    喔,因為這些衣服根本就是文青的代名詞!至少,是一位數學家研究發現的!所以我做了一整集有關於這個的影片

  • Grab your fancy coffee and give it a click.

    拿好你貴鬆鬆的咖啡,點擊這個連結吧

  • Hipsters are difficult to describe as a group.

    文青很難被區分成一個特定的族群

  • But we know one when we see one, right?

    但當我們總能知道誰是個文青,對吧?

  • And a new mathematical neural science paper explains why that is:

    而有篇神經科學研究在數學上特別解釋了這個現象:

  • The Hipster Effect. When anti-conformists all look the same

    當反保守派的人們穿著打扮都很相似時,被稱為文青效應

  • Do you love laundry? Do you hate it? Are you super meticulous about how things get folded?

    你喜歡洗衣服嗎?或著對洗衣服恨之入骨?還是你折衣服都要折成豆干一樣?
