牛仔裤是棉布制做的，现在的牛仔裤面料相当的丰富，不单纯是棉布了，

牛仔裤是李维斯去西部淘金时，发现淘金的人多，但是真正陶倒金的人不多，但是这些人的衣服却非常容易坏，于是，李维斯用帐篷的帆布做成了世界上第一条牛仔裤，并且因此成为世界牛仔裤大王，

牛仔裤的历史和来历

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世纪的法国，有种布料是” serge de Nimes”，同时令一种布料叫做”nim”，这两种布料都含有羊毛．

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. 对于”denim”这个词是不是从”Serge de nimes”来的一直都有疑问．

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”这个词也同时存在了，这是个意大利词，意思是由纯棉，亚麻或羊毛组成的布料．之后被出口到了英国，到了18世纪，牛仔布料完全变成纯棉了，主要用于给男人做衣服，它出名在即使多次洗涤后仍然可以使用很久．

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. 其实”denim”和”Jean”是有一定区别的：denim是用一条带色的线和一条白线构成，而”jean”是由两条同色线编织而成的．
