牛仔褲是棉布製做的，現在的牛仔褲麵料相當的豐富，不單純是棉布了，

牛仔褲是李維斯去西部淘金時，發現淘金的人多，但是真正陶倒金的人不多，但是這些人的衣服卻非常容易壞，於是，李維斯用帳篷的帆布做成了世界上第一條牛仔褲，並且因此成為世界牛仔褲大王，

牛仔褲的曆史和來曆

History of Denim

There are a few schools of thought on the derivation of the word denim. The serge de Nimes fabric traces back to France prior to the 17th century. At the same time, there was also a fabric known in France as nim. Both fabrics were composed partly of wool. 在17世紀的法國，有種布料是” serge de Nimes”，同時令一種布料叫做”nim”，這兩種布料都含有羊毛．

Serge de Nimes was also known in England before the end of the 17th century. The question then arises: was this fabric imported from France or was it an English fabric bearing the same name? Fabrics which were named for a certain geographic location were often also made elsewhere; the name was used to lend a certain cachet to the fabric when it was offered for sale. Therefore a serge de Nimes purchased in England was very likely also made in England, and not in Nimes, France.

There still remains the question of how the word denim is thought to have descended from the word serge de Nimes. Serge de Nimes was made of silk and wool, but denim has always been made of cotton. Again, this relation between fabrics is in name only, though both fabrics are a twill weave. Is the real origin of the word denim serge de nim, meaning a fabric that resembled the part-wool fabric called nim? Was serge de Nimes more well-known than serge de nim and mis-translated when it crossed the English Channel? It's likely we will never really know. 對於”denim”這個詞是不是從”Serge de nimes”來的一直都有疑問．

To confuse things even more, another fabric known as jean also existed at this same time. Research on this textile indicates that it was a fustian - a cotton, linen and/or wool blend - and that fustian from Genoa, Italy was called jean. This is evidence of a fabric being named for a place of origin. It was apparently quite popular and imported into England in large quantities during the 16th century. By the end of this period, jean was being produced in Lancashire. By the 18th century, jean cloth was made completely of cotton and used to make men's clothing, valued especially for its property of durability even after many washings. 更加奇怪的是”Jean”這個詞也同時存在了，這是個意大利詞，意思是由純棉，亞麻或羊毛組成的布料．之後被出口到了英國，到了18世紀，牛仔布料完全變成純棉了，主要用於給男人做衣服，它出名在即使多次洗滌後仍然可以使用很久．

Denim's popularity was also on the rise. It was stronger and more expensive than jean, and though the two fabrics were very similar in some ways, they did have one major difference: denim was made of one colored thread and one white thread; jean was woven of two threads of the same color. 其實”denim”和”Jean”是有一定區別的：denim是用一條帶色的線和一條白線構成，而”jean”是由兩條同色線編織而成的．
