ポリエステル
解説 Definition
polyester は、ポリエステルという意味です。衣類や布、繊維素材について使われ、日本語のカタカナ語とほぼ同じ意味ですが、英語では素材名として数えられない名詞として扱われることが多いです。
Polyester is a synthetic polymer containing repeated ester groups, widely made into fibers and fabrics for clothing and other products. As the name of a material, it is generally an uncountable noun in expressions such as “made of polyester.”
覚え方のコツ Memory Tip
poly-「多数」と ester「エステル」を組み合わせた化学名で、エステル結合が繰り返される高分子と捉えます。衣類では made of polyester、polyester fabric の形が典型です。素材名なので通常は不可算名詞となり、a polyester とはせず、cotton や nylon と対比して覚えます。
Break polyester into poly-, meaning “many,” and ester, the chemical group repeated along the polymer chain. This structure explains the name without relying only on the Japanese loanword. For everyday use, picture clothing labels and learn the combinations “made of polyester” and “polyester fabric.” Like cotton and nylon when they name materials, polyester is usually uncountable, so English normally says “This shirt is made of polyester,” not “made of a polyester.” Its frequent contrast with cotton also recalls its common use as a quick-drying synthetic fiber.
例文
This shirt is made of polyester.
このシャツはポリエステル製です。
Polyester dries faster than cotton.
ポリエステルは綿よりも早く乾きます。
The jacket uses polyester fabric for the outer layer.
そのジャケットは外側の生地にポリエステルを使っています。

polyester の語源・成り立ち Etymology
1929年に作られた化学語で、polymer＋ester からの合成です。poly- はギリシャ語 polys「多い」、ester はドイツ語由来の化学語で、「エステル結合が多数つながる高分子」をそのまま名づけています。polymer や polyglot の poly- も同根です。
Polyester is a modern chemical term formed from poly- and ester. The prefix poly- comes from Greek polys, meaning “many,” while ester is a chemical term that entered scientific vocabulary through German. The name describes polymers whose molecular chains contain many ester linkages. The word was coined in the early twentieth century and later became widely associated with synthetic textile fibers made from such polymers.
