Kodi ndi chiyaninsungwiulusi?
Ulusi wa nsungwi ndi ulusi wopangidwa ndi matabwa a nsungwi ngati zinthu zopangira, pali mitundu iwiri ya ulusi wa nsungwi: ulusi woyamba wa cellulose ndi ulusi wobwezeretsedwa wa cellulose. Ulusi woyamba wa nsungwi womwe ndi ulusi woyambirira wa nsungwi, ulusi wobwezeretsedwa wa cellulose wa nsungwi uli ndi ulusi wa pulp wa nsungwi ndinsungwiulusi wa makala.
Ulusi wa nsungwi wosaphika ndi ulusi wachilengedwe womwe umapezeka pokonza nsungwi pogwiritsa ntchito njira zakuthupi zochotsera gum. Njira yopangira ndi iyi: zinthu za nsungwi → tchipisi ta nsungwi → tchipisi ta nsungwi zotentha → kuphwanya kuwonongeka → kuchotsa gum mu enzyme yachilengedwe → carding ulusi → ulusi wa nsalu. Chofunikira chachikulu pa njirayi ndi chachikulu komanso chovuta kupanga, kotero zinthu zopangidwa ndi ulusi wa nsungwi zomwe zili pamsika zidakali ulusi wa nsungwi.
Ulusi wa nsungwi ndi njira ya mankhwala yosungunula nsungwi kukhala nsungwi ya viscose yopangidwa ndi zamkati, munjira yopota yopangidwa ndi ulusi, yomwe imagwiritsidwa ntchito makamaka pazovala, zofunda. Zinthu zodziwika bwino za ulusi wa nsungwi m'zofunda ndi izi: mphasa ya ulusi wa nsungwi, malaya achilimwe a nsungwi, bulangeti la ulusi wa nsungwi, ndi zina zotero.
Ulusi wa makala a nsungwi umapangidwa ndi nsungwi kukhala ufa wocheperako, kudzera mu njira yapadera yopangira yankho la viscose spinning, kudzera mu njira yozungulira kuti apange zinthu za ulusi, zomwe zimagwiritsidwa ntchito kwambiri muzovala zamkati, masokosi, matawulo.

Ulusi wa bamboo ndi wotchuka chifukwa chiyani?
1, imabwera ndi zotsatira zoziziritsa
Chilimwe chotentha komanso chomata nthawi zonse chimapangitsa anthu kufunafuna kuziziritsa zinthu zabwino mosazindikira, ndipo ulusi wa nsungwi umabweretsa mphamvu yake yozizira.
Ulusi wa nsungwi ndi wopanda kanthu, mipata ya ulusi ngati mitsempha yamagazi pamwamba pa ulusi, kotero imatha kuyamwa madzi ambiri nthawi yomweyo ndikuwutentha, 36 ℃, chinyezi cha 100%, kuchuluka kwa chinyezi cha ulusi wa nsungwi kumabwerera mpaka 45%, mpweya wopuma ndi wokwera katatu kuposa thonje, kotero kuyamwa kwa chinyezi ndikuuma mwachangu, kumabwera ndi mphamvu yozizira. (Chitsime cha deta: Global Textile Network)
Mu nyengo yotentha, khungu likakhudzana ndi nsalu ya ulusi wa nsungwi, kutentha kwa thupi kumakhala kotsika ndi 3 ~ 4℃ kuposa thonje wamba, ndipo nthawi yachilimwe thukuta limathanso kukhala louma kwa nthawi yayitali, osati lomata.
2、Sizosavuta kuumba, zomata, zonunkha
Chinthu chodetsa nkhawa kwambiri m'chilimwe ndi kuchuluka kwa thukuta lomwe limamatira ku zofunda, zomwe zimapangitsa kuti zofundazo zikhale zomata, zowuma, komanso fungo.
Ulusi wa nsungwi kuwonjezera pa kuyamwa bwino chinyezi ndi mpweya wofewa kuti nsaluyo ikhale youma, womwe uli ndi gawo la "bamboo Kun", ulinso ndi mphamvu zachilengedwe zotsutsana ndi mabakiteriya, zomwe zingapewe kufalikira kwa mabakiteriya, kotero kuti nsalu za nsungwi ngakhale m'chilimwe chofunda komanso chonyowa sizimakhala ndi nkhungu, sizinunkha, sizimamatira.
3, Omasuka komanso ofewa
Ulusi wa nsungwi wopanda kupindika, wosalala, nsalu yolukidwayo ndi yosamala komanso yosalala, yopepuka komanso yomasuka, ndipo kukhudzana ndi khungu kungapangitse anthu kumva ngati akusamalidwa.
4. Zobiriwira, thanzi komanso zokhazikika
Poyerekeza ndi zinthu zina zopangira ulusi wa cellulose monga matabwa, nthawi yokulira nsungwi ndi yochepa, zaka 2-3 zingagwiritsidwe ntchito, chifukwa zofooka za zinthu zimakhala ndi mphamvu yochepetsera. Ndipo ulusiwo ukhoza kuwonongeka mwachilengedwe m'chilengedwe, sudzawononga chilengedwe.
Ubwino womwe uli pamwambapa umapangitsa kuti ulusi wa nsungwi ugwirizane ndi zosowa za anthu pa bedi la chilimwe, chilimwe chilichonse chimakhala chotchuka kwambiri. Koma apa pali mtunda wochepa woti ukukumbutseni chinthu chimodzi: bedi la nsungwi lomwe likupezeka pamsika masiku ano makamaka mu mawonekedwe osakanikirana ndi thonje (lomwe limadziwikanso kuti thonje la nsungwi), ndipo ambiri mwa iwo ndi zinthu zabodza, muyenera kusamala kuti muzindikire mukamagula.
