纖維係咩黎?咩製成纖維??
點解有D纖維製的衣服好薄,但係好保溫?
詳盡D thz!!!

重點係點解纖維製既衫,雖薄但能保溫????

✔ 最佳答案
纖維是指由連續或不連續的細絲組成的物質,例如麻繩。 Fibers are often used in the manufacture of other materials. They can be spun into filaments, thread, or rope. They can be used as a component of composite materials. They can also be matted into sheets to make products such as paper or felt.
Fibers come from a wide variety of sources:

Natural fiber include those made out of plants, animal and mineral sources.
Natural fibers can be classified according to their origin.



Vegetable fibers generally comprise cellulose: examples include cotton, linen, jute, flax, ramie, sisal and hemp. Cellulose fibers serve in the manufacture of paper and cloth.
Animal fibers include spider silk, sinew, hair, and wool.
礦物纖維,例如石棉,由非有機物質組成. 石棉是維一自然存在的礦物纖維

人造纖維,是指經加工過而製成的纖維,包括玻璃纖維、尼龍等

Synthetic fibers are a subset of man-made fibers, which are based on synthetic chemicals rather than arising from natural chemicals by a purely physical process. Such fibers are quite often made from nylon, polyester, or acrylic polymers, although pure polyacrylonitrile fibers are mostly used to make carbon fiber. More exotic fibers have strong bonding between polymer chains (i.e. aramids), or extremely long chains (i.e., Dyneema). Elastomers can even be used, i.e. in spandex.

衣著常用纖維介紹
l 衣料的主要來源為植物纖維和動物纖維。例如棉、大麻、亞麻等植物纖維製品,廣為人類所喜愛,不但可以保暖,夏天穿著有涼快的感覺。動物纖維的蠶絲,柔軟而具有美麗光澤,自古即為高貴的衣料;羊毛纖維保暖性特優,易染色,也是人類愛好的衣料。惟近年來由於人類的大量需求,植物纖維及動物纖維產量有限,材料科學家發明了較便宜的人造纖維,便逐漸取代了天然纖維,人造纖維可分為再生纖維及合成纖維兩大類:
1 再生纖維:在製造過程中,先將天然原料的植物纖維素予以溶解再成型,製成絲狀纖維。人造絲具有光澤,在稀酸或鹼液中,性質安定,與植物纖維一樣容易染色和漂白,可做良好的衣料。
2 合成纖維:合成纖維並非由天然材料製成,而是從石油化學原料,經人工方法合成而得名,其纖維堅韌而長,可製造各種衣料及其他編織物。合成纖維較天然纖維強韌,對化學藥品的抵抗力尤佳,惟吸水性較差,因此往往與羊毛或棉混紡成市售的衣料。

l 辨認纖維時可使用物理或化學方法來幫助我們辨認,天然纖維中來自動物的羊毛、蠶絲等,燃燒時有如同羽毛燃燒時所發出的氣味;來自植物的天然纖維燃燒時,發出如同濾紙燃燒時所放出的氣味。許多合成纖維燃燒後,纖維絲末端會形成球狀。依照經濟部商品標示法的規定,服飾上必須標示纖維成分,下表為常用之天然及人造纖維種類法定學名或慣用名稱中英文對照表。
