Kukula kwa dziko lonse lapansimakampani opanga nsaluunyolo wawonjezera kuchuluka kwa nsalu zomwe munthu amadya pachaka kuchoka pa 7kg kufika pa 13kg, ndi kuchuluka kwa matani opitilira 100 miliyoni, ndipo kupanga nsalu zotayidwa pachaka kwafika matani 40 miliyoni. Mu 2020, dziko langa lidzabwezeretsanso matani 4.3 miliyoni a nsalu, ndipo kutulutsa kwa ulusi wa mankhwala kudzapitirira matani 60 miliyoni. Ngakhale kuti chiwerengero cha nsalu zomwe zimatumizidwa kunja chili chokwera, chiŵerengero cha kubwezeretsanso n'chochepa. Pakadali pano nsalu zotayidwa zoposa 2/3 padziko lonse lapansi zomwe sizinathe kukonzedwanso ndikubwezeretsedwanso.

Nsalu zobwezerezedwanso nthawi zambiri zimaonedwa kuti zimabwezerezedwansonsaluzomwe zingagwiritsidwenso ntchito, ndipo magwiridwe antchito a zinthu zomwe zapangidwanso ndi ofanana, ndipo ali ndi mtengo wapamwamba.nsalu imodziPa nsalu zomwe "zimatayidwa" zomwe zimatha kuwonongeka, zomwe sizili ndi phindu lachuma loti zibwezeretsedwe mwachangu, zitha kupakidwa manyowa. Kuwonjezera pa lingaliro ili la chuma chozungulira, ukadaulo wamafakitale umagawa kubwezeretsanso zinthu m'mitundu iwiri: kukweza ndi kuchepetsa.

Njira zobwezeretsanso nsalu zimaphatikizapo njira zamakina, zakuthupi ndi zamankhwala. Njira yamakina ndi kukonza nsalu kukhala timizere topyapyala kapena ulusi kuti zizungulirenso kapena kusintha cholinga chachikulu cha nsalu; njira yeniyeni makamaka ndi ulusi wopangidwa, makamaka ulusi wopangidwa ndi kusungunuka, womwe umasungunuka kutentha kwambiri kuti nsalu zisungunuke. Pambuyo posefa zonyansa, zimatha kupota kapena kugwiritsidwa ntchito pazinthu zina. Zipangizo zina zophatikizika za ulusi wochita bwino zimatha kuchotsa epoxy resin kutentha kwambiri, kubwezeretsa mkhalidwe wa ulusi, ndikugwiritsidwa ntchito pazinthu zopanda nsalu kudzera mu njira zodula ndi kuphwanya; njira zamankhwala makamaka ndi zamitundu yosiyanasiyana ya nsalu. Kulekanitsa ulusi kumabwezeretsedwanso padera, ndipo nthawi zambiri zimagwiritsidwa ntchito kuyeretsa zinthu zobwezerezedwanso, kuchotsa bwino zonyansa ndi utoto, ndikuyika kukweza ndi kukonzanso.

Mu 2020, ulusi wa polyester womwe dziko langa limatulutsa unali matani 49.3575 miliyoni, womwe ndi 72% ya zonse, thonje linali matani 8.6 miliyoni, lomwe ndi 12%, viscose linali matani 3.95 miliyoni, lomwe ndi 5.8%, nayiloni linali 5.6%. Ulusi wotsalawo umawonjezeka kufika pa 4%. Pofuna kuonetsetsa kuti chakudya chikupezeka, ulusi wachilengedwe monga thonje, nsalu, ndi ubweya ukutsika kwambiri. Ndi njira yosinthira ulusi wachilengedwe ndi ulusi wopangidwa. Gwero la ulusi wopangidwa limatha kusankha zinthu zopangidwa ndi zamoyo, ndipo zinthu zobwezerezedwanso ziyenera kugwiritsidwa ntchito pang'onopang'ono kuchotsa kudalira kwambiri zinthu zosabwezerezedwanso. Izi sizongofunika posunga zinthu, kuteteza chilengedwe ndikuchepetsa kugwiritsidwa ntchito kwa nthaka yolimidwa, komanso ndizofunika kwambiri pakupanga ndi chitukuko cha chuma chozungulira.
