Kulumikizana ndi Mpweya (Kugwirizana ndi Kutentha)
Kulumikiza kudzera mu mpweya ndi mtundu wa mgwirizano wotentha womwe umaphatikizapo kugwiritsa ntchito mpweya wotentha pamwamba pa nsalu yopanda ulusi. Panthawi yogwirizanitsa mpweya, mpweya wotentha umadutsa m'mabowo omwe ali pamwamba pa nsalu yopanda ulusi.

Kusungunuka
Zopanda nsalu zopangidwa ndi Meltblown zimapangidwa potulutsa ulusi wa polima wosungunuka kudzera mu ukonde wopota kapena die wokhala ndi mabowo okwana 40 pa inchi iliyonse kuti apange ulusi wautali woonda womwe umatambasulidwa ndikuzizidwa podutsa mpweya wotentha pamwamba pa ulusiwo ukagwa kuchokera ku die. Ukonde wotsatira umasonkhanitsidwa kukhala mipukutu kenako nkusinthidwa kukhala zinthu zomalizidwa.

Spunlace (Hydrotentanglement)
Spunlace (yomwe imadziwikanso kuti hydroentanglement) ndi njira yolumikizira maukonde onyowa kapena ouma opangidwa ndi carding, airlaying kapena wet-laying, nsalu yolumikizidwayo ikakhala yopanda ulusi. Njirayi imagwiritsa ntchito madzi othamanga kwambiri omwe amalowa mu ukonde, amagunda lamba wotumizira (kapena "waya" monga momwe zimakhalira mu conveyor yopanga mapepala) ndikubwerera m'mbuyo zomwe zimapangitsa kuti ulusiwo ugwirizane. Nsalu zosalukidwa za Spunlace zimagwiritsidwa ntchito ndi ulusi waufupi wofunikira, wotchuka kwambiri ndi ulusi wa viscose ndi polyester koma polypropylene ndi thonje zimagwiritsidwanso ntchito. Ntchito zazikulu za spunlace zikuphatikizapo zopukutira, zophimba nkhope ndi zinthu zachipatala.

Spunlaid (Spunbond)
Zopangidwa ndi spunbond, zomwe zimatchedwanso spunbond, zopangidwa ndi nonwoven zimapangidwa nthawi imodzi mosalekeza. Ulusi umapota kenako umafalikira mwachindunji mu ukonde ndi zopinga kapena zimatha kuyendetsedwa ndi mitsinje ya mpweya. Njira imeneyi imapangitsa kuti lamba lizithamanga mofulumira, komanso kuti pakhale mtengo wotsika.

Kusungunuka/SMS
Spunbond yaphatikizidwa ndi nsalu zopanda ulusi zomwe zimasungunuka, zomwe zimapangitsa kuti zikhale chinthu chopangidwa ndi zigawo zotchedwa SMS (spun-melt-spun). Nsalu zopanda ulusi zomwe zimasungunuka zimakhala ndi ulusi wopyapyala kwambiri koma si nsalu zolimba. Nsalu za SMS, zopangidwa kuchokera ku PP kwathunthu, sizimalowa m'madzi ndipo zimakhala bwino mokwanira kuti zigwiritsidwe ntchito ngati nsalu zotayidwa. Nsalu zosungunuka nthawi zambiri zimagwiritsidwa ntchito ngati zosefera, zomwe zimatha kugwira tinthu tating'onoting'ono kwambiri. Spunlaid imalumikizidwa ndi utomoni kapena kutentha.

Madzi Onyowa
Mu ndondomeko yonyowa, ulusi wokhazikika wa ulusi wofika 12 mm, womwe nthawi zambiri umasakanizidwa ndi viscose kapena pulp yamatabwa, umayikidwa m'madzi, pogwiritsa ntchito matanki akuluakulu. Pambuyo pake, ulusi wa madzi kapena kufalikira kwa madzi kumapopedwa ndikuyikidwa nthawi zonse pa waya wopangidwa. Madziwo amayamwa, kusefedwa ndikubwezeretsedwanso. Kupatula ulusi wopangidwa, ulusi wa ceramic ndi carbon ukhoza kukonzedwa.
