M'zaka zaposachedwa, anthu akuyang'ana kwambiri chitetezo cha thanzi ndi chilengedwe, ndipo ulusi wa zomera wakhala wotchuka kwambiri.Nkhokwe za Banana zasinthidwanso chidwi ndi mafakitale a nsalu.
Nthochi ndi imodzi mwa zipatso zomwe anthu amakonda kwambiri, zomwe zimadziwika kuti "chipatso chachimwemwe" ndi "chipatso cha nzeru".Pali mayiko a 130 omwe amalima nthochi padziko lonse lapansi, omwe amapanga kwambiri ku Central America, akutsatiridwa ndi Asia.Malinga ndi ziwerengero, ndodo zopitirira matani 2 miliyoni za nthochi zimatayidwa chaka chilichonse ku China chokha, zomwe zimayambitsa kutaya kwakukulu kwazinthu. ndodo zotulutsa ulusi wansalu (ulusi wa nthochi) wakhala nkhani yovuta kwambiri.
Ulusi wa nthochi umapangidwa kuchokera ku ndodo ya nthochi, makamaka imapangidwa ndi cellulose, semi-cellulose ndi lignin, yomwe imatha kugwiritsidwa ntchito popota thonje pambuyo popukuta mankhwala.Kugwiritsa ntchito ma enzyme ndi ma oxidation amankhwala ophatikizira njira zochizira, Kupyolera mu kuyanika, kuyengedwa, ndi kuwonongeka, CHIKWANGWANI chimakhala ndi kuwala, kuwala bwino, kuyamwa kwakukulu, antibacterial wamphamvu, kuwonongeka kosavuta komanso kuteteza chilengedwe ndi ntchito zina zambiri.

Kupanga nsalu ndi ulusi wa nthochi sikwachilendo.Ku Japan kumayambiriro kwa zaka za m'ma 1300, kupangidwa kwa fiber kunapangidwa kuchokera kumitengo ya nthochi.
Ulusi wa nthochi ndi umodzi mwa ulusi wamphamvu kwambiri padziko lonse lapansi, ndipo ulusi wachilengedwe wotha kuwonongekawu ndi wokhalitsa.

Ulusi wa nthochi ukhoza kupangidwa kukhala nsalu zosiyanasiyana malinga ndi kulemera ndi makulidwe osiyanasiyana a tsinde la nthochi zosiyanasiyana.Ulusi wolimba ndi wandiweyani umachokera kunja, pamene mkati mwake umachokera ku ulusi wofewa.
Ndikukhulupirira kuti posachedwapa, tidzawona mitundu yonse ya nthochi zopangidwa ndi zovala m'malo ogulitsira.
