长袖工衣在我国社会的位置是有前史能够追溯的。就像在世界别的当地相同，兵士穿长袖工衣，一是为了区别军事派系，二是为了供给维护。每一个朝代的兵士长袖工衣的个性都不相同，从东周时期手绘兵士的画像能够看出，他们穿戴沉重的靴子和长袖工衣以维护手臂和身体，相同的，从隋朝时期兵士的画像能够看出，他们都披着一层一层的铠甲。长袖工衣常常是兵士在激烈战役中好的维护。

Uniforms were also designed to show status and mark levels of authority. In China, the Terracotta Warriors in Xi’an were molded to wear styles commonly found in the Qin Dynasty (221-207 B.C.). Officers' ranks were discernible by their dress, with generals wearing a dual long jacket, long pants, thigh protectors, a crest hat and a pair of boots with square tips.

Textile manufacturers can coat already-made fabric with the liquid. The coated fabric then has a self-repair ability automatically built into it, said Demirel, who led the research.

试验的主导人德米雷尔表明，纺织物生厂商能够在现已出厂的布料上涂一层这种液体。带有这种涂层的布料自但是然就具有了自我修正才能。

It's a simple process. You put a few drops of the liquid on the tear, apply warm water and press the edges together for a minute. The fabric reattaches and essentially self-repairs, said Melik Demirel, a professor of engineering science and mechanics at Penn State.

修正过程很简略。宾夕法尼亚州立大学工程科学和力学***梅利克·德米雷尔表明，只需求滴几滴这种***液体在破碎的织物上，以温水热敷，将破了的纺织物压在一同一分钟，问题就能轻松处理。

神奇!新式织物撕破后遇水能自愈!
