Humans have learnt many things from nature. These things have helped us in our daily life. The latest thing is self-repairing clothing. Scientists have developed a special way for clothing to repair rips and tears by itself, without the need for sewing. It works with materials such as cotton, linen and wool. The scientists are from the Naval Research Office and Pennsylvania State University in the USA. Scientists Dr. Walter Dressick and Dr Melik Demirel looked at how squid can cling on to things so well. The research team found a protein in the rings of teeth that cover the suckers on a squid. The protein is similar to the one found in the silk that spiders use to make spider webs. It is very strong and elastic (stretchy).

人類從大自然中學(xué)到了許多。這些有助于我們?nèi)粘Ｉ?。最新研究成果是自行修?fù)衣物?？茖W(xué)家研發(fā)了一種能夠讓衣物自行修復(fù)裂痕的特殊方法，無需手動縫紉。適用于像棉布類、亞麻類以及羊毛類等服裝。科學(xué)家來自美國海軍研究所和賓州州立大學(xué)。沃爾特·德里斯科和梅利克·德米雷爾博士對魷魚的吸附力進(jìn)行了研究。研究團(tuán)隊在覆蓋吸盤的一圈牙齒上發(fā)現(xiàn)了一種蛋白質(zhì)。此類蛋白質(zhì)與蜘蛛網(wǎng)的蠶絲相類似。彈性和韌勁十足。

The new protein has been developed as part of a coating, which is put on clothes. When the coating is dipped in water, the area around the rip or tear joins together in less than a minute. This could help clothes last longer and save us money. It could also be useful for military and survival clothes. People like soldiers and mountaineers would be safer if they had clothes that repaired quickly and easily. Professor Demirel spoke about the invention. He said: "The coatings are thin, less than a micron, so they wouldn't be noticed in everyday wear." He added: "Even thin, they increase the overall strength of the material. For the first time, we are making self-healing textiles."

人們將此類新型蛋白質(zhì)應(yīng)用在了衣服涂料上。一旦涂料著水，裂痕周圍區(qū)域?qū)⒃诓坏揭环昼妰?nèi)愈合。此舉將延長衣服壽命，為您節(jié)省資金。它也可應(yīng)用于軍事和野外生存衣。如果它能立即修復(fù)，那么對于士兵或登山者來說就更加安全。德米雷爾教授談及了此項發(fā)明。他認(rèn)為：“這種涂料很薄，不到一微米，我們很難在日常衣物中發(fā)現(xiàn)它。”他還表示：“盡管它非常輕薄，但卻增加了材質(zhì)的韌性。這也是我們首次研發(fā)自行修復(fù)紡織品。
