Thread Content
The materials used in the clothes we wear include polyester, spandex, acrylic, cotton, wool, and more. Polyester: PET fibers, Polyethylene Terephthalate, polyethylene terephthalate – a material that is well-known to many people; fibers of this type are usually produced through melt spinning ； Spandex: PUU fiber, polyurethane urea; it is typically obtained by pre-polymerizing diphenylmethane diisocyanate (MDI) and polytetramethylether glycol (PTMEG), then extending the polymer chain using ethylenediamine or malondiamine, and finally producing it through dry spinning ； Acrylic: PA fibers, Polyacrylonitrile, polyacrylonitrate; synthetic wool, which is what we commonly refer to as \"cashmere\"” ； Cotton: a plant-based natural polymer material; in fact, most of it is viscose fiber, and true pure cotton is hard to find ； Wool: a natural animal-based polymer material that is expensive; especially cashmere. In an ordinary coat, if 70% of the material is wool, the price is likely to be close to a thousand yuan. What other materials can you name that are polymers?
What category did early acrylic and polyester carded fabrics belong to?
To be precise, it’s indeed cool, because it keeps you cool when worn. Fashion; that’s what people called it at the time (it was indeed cool). In the early 1980s, wearing dacai liang was a major fashion trend of the time. It was initially worn by women, mainly used to make shirts, and was usually available in white and blue colors. Later, various patterns were introduced, adding a touch of color to the monotonous palette of daily life. Women saved up money to purchase dacai liang, which helped transform the abstract and bulky image of women back toward the true meaning of the word “woman”. The men, not wanting to be left out, also put on bright white cotton shirts and tucked their cuffs into their pants. In the 1990s, liang was indeed replaced by pure cotton and linen. Those who lived in the 80s and 90s surely know that rayon was a popular and fashionable material. It is indeed cool; it’s a polyester fabric, available in pure form as well as in blends with cotton and wool, and is usually used to make shirts and short-sleeved garments. Clothes made of rayon are durable, do not lose their shape, are easy to wash, and dry quickly. Those who lived in the 1970s and 1980s were very familiar with it: it was smooth and sleek, durable and quick to dry, did not require ironing, had bright colors that did not fade, especially the vivid hues achieved through printing. For Chinese people accustomed to rough fabrics and simple, dull-colored clothes, it was undoubtedly a huge visual shock. Back then, there were no air conditioners, and even fans were rare; people relied on banana leaves to cool their bodies. In that era, wearing a Acrylic shirt was essential; if having one such shirt wasn’t considered fashionable, it was at least a stylish and necessary accessory.
Is dacron a type of polyester mixture? Or some kind of polyester product?
It’s relatively durable, but it doesn’t wick sweat
I learned a few more things; thanks to the original poster
