Zomwe zili pamwambazi ndizo njira zazikulu zamakono zopangira nsalu zopanda nsalu, iliyonse ili ndi mawonekedwe ake apadera komanso mawonekedwe a mankhwala kuti akwaniritse zofunikira za nsalu zopanda nsalu m'madera osiyanasiyana ogwiritsira ntchito. Zomwe zimagwiritsidwa ntchito paukadaulo uliwonse wopanga zitha kufotokozedwa mwachidule motere:
-Ukadaulo wopanga zowuma: nthawi zambiri zimakhala zoyenera kupanga zinthu zopanda nsalu zokhala ndi mphamvu zambiri komanso kukana kuvala bwino, monga zosefera, ma geotextiles, ndi zina zambiri.
-Tekinoloje yopanga madzi: yoyenera kupanga nsalu zofewa komanso zoyamwa zosalukidwa, monga zinthu zaukhondo, zovala zamankhwala, ndi zina.
-Tekinoloje yopangira makina osungunula: Imatha kupanga nsalu zopanda nsalu zokhala ndi ulusi wapamwamba kwambiri komanso kusefera kwabwino, koyenera minda yachipatala, kusefera, zovala ndi zinthu zapakhomo.
-Kuphatikizika kwaukadaulo wopanga: Kuphatikiza zabwino zamaukadaulo angapo, nsalu zophatikizika zopanda nsalu zokhala ndi zinthu zinazake zimatha kupangidwa, ndikugwiritsa ntchito mosiyanasiyana.
Zopangira zoyenera kupanga nsalu zopanda nsalu makamaka zimaphatikizapo:
1. Polypropylene (PP): Ili ndi makhalidwe opepuka, kukana mankhwala, kukana kutentha, etc., ndipo amagwiritsidwa ntchito kwambiri mu spunbond nonwoven nsalu, meltblown nonwoven nsalu, etc.
2. Polyester (PET): Ili ndi zida zamakina kwambiri komanso kulimba, ndipo ndi yoyenera ku nsalu za spunbond nonwoven, spunlace nonwoven nsalu, needpunch nonwoven fabrics, etc.
3. Viscose CHIKWANGWANI: ali wabwino mayamwidwe chinyezi ndi kusinthasintha, oyenera spunlace nsalu sanali nsalu, mankhwala aukhondo, etc.
4. Nayiloni (PA): Ili ndi mphamvu zabwino, kukana kuvala, ndi kulimba mtima, ndipo ndi yoyenera pa singano yokhomeredwa ndi nsalu zopanda nsalu, zosokedwa zopanda nsalu, ndi zina zotero.
5. Acrylic (AC): Ili ndi zotsekemera zabwino komanso zofewa, zoyenera kunyowa nsalu zopanda nsalu, zinthu zaukhondo, ndi zina zotero.
6. Polyethylene (PE): Ndi yopepuka, yosinthasintha, komanso yosagwirizana ndi mankhwala, oyenera nsalu zonyowa zopanda nsalu, zinthu zaukhondo, ndi zina zotero.
7. Polyvinyl Chloride (PVC): Ili ndi mphamvu yabwino yoyaka moto komanso yosalowa madzi, ndipo ndi yoyenera kwa nsalu zonyowa zopanda nsalu, nsalu zopanda fumbi, ndi zina zotero.
8. Cellulose: Imakhala ndi mayamwidwe abwino a chinyezi komanso kuyanjana ndi chilengedwe, ndipo ndiyoyenera nsalu zopanda nsalu zonyowa, mapepala opanda fumbi, ndi zina zotero.
9. Ulusi wachilengedwe (monga thonje, hemp, etc.): kukhala ndi mayamwidwe abwino a chinyontho ndi kufewa, oyenera nkhonya ya singano, spunlace nsalu zopanda nsalu, zinthu zaukhondo, ndi zina zotero.
10. Zingwe zobwezerezedwanso (monga poliyesitala, zomatira zobwezerezedwanso, ndi zina zotero): ndizogwirizana ndi chilengedwe komanso zoyenera njira zosiyanasiyana zopangira nsalu zopanda nsalu.
Kusankhidwa kwa zipangizozi kumadalira gawo lomaliza logwiritsira ntchito komanso zofunikira zogwirira ntchito za nsalu zopanda nsalu.
