Nsalu ya polyester viscose ndi nsalu yogwira ntchito yosakanikirana ndi polyester (polyester fiber) ndi viscose fibers. Zimaphatikiza kuuma ndi kuvala kukana kwa polyester ndi kufewa komanso kupuma kwa viscose ndipo amagwiritsidwa ntchito kwambiri muzovala, nsalu zapakhomo, ndi zina. Kapangidwe kake kamakhala ndi njira zinayi: kukonza zinthu, kupota, kuluka, ndi kumaliza.
Panthawi yokonzekera zopangira, kuchuluka kwa fiber kuyenera kuyendetsedwa mosamalitsa. Nthawi zambiri, chiŵerengero cha poliyesitala ku viscose chimasinthidwa malinga ndi momwe nsalu zimafunira (zofanana ndi 65:35 kapena 50:50). Ulusi wa polyester umapangidwa kuchokera ku tchipisi posungunula kupota, pomwe ulusi wa viscose umapezeka posungunula matabwa kapena ma linter a thonje mu njira ya alkaline kenako nkumapota. Ulusi wonsewo umatsegulidwa, kutsukidwa, ndi kusakaniza padera kuti zitsimikizike kuti zimagwirizana.
Panthawi yopota, ulusi wosakanizidwa umapangidwa kukhala ulusi pogwiritsa ntchito mphete yopota kapena yotsegula-mapeto. Unyinji wa viscose ndiwowoneka bwino kwambiri ndipo umayenera kukonzedwa pamalo onyezimira-kuteteza magetsi osasunthika. Ponena za polyester, kutsika kwamafuta pa kutentha kwakukulu kumafuna chidwi. Ulusiwo ukapota, umapota, kuwirikiza, ndi kupindika kuti ukhale wolimba komanso wofanana.
Panthawi yoluka, kuluka kapena kuluka kumasankhidwa malinga ndi momwe nsaluyo ikufunira. Kuluka kumagwiritsa ntchito nsalu zomveka bwino komanso zozungulira, kutsindika kukhazikika kwapangidwe; kuluka kumaika patsogolo elasticity ndi chitonthozo. Zida zoluka zimafunikira kusintha magawo amphamvu potengera mawonekedwe a ulusi wosakanikirana kuti ulusi wa viscose usagwedezeke chifukwa cha mikangano.
Kumaliza ndikofunika kwambiri kuti nsalu igwire bwino ntchito ndipo kumaphatikizapo masitepe monga kukongoletsa, kuyika, kufewetsa, ndi kuchepera-pambuyo pake. Ulusi wa polyester umayikidwa pa kutentha kwambiri kuti ukhale wokhazikika, pomwe ulusi wa viscose umafunika chithandizo chochepa cha asidi kuti achepetse zotsalira za alkali kuti amve bwino. Pomaliza, kuyang'anitsitsa kwabwino kumatsimikizira kuti nsaluyo ikugwirizana ndi miyezo ya kufulumira kwa mtundu, kuchepa, ndi zina.
Kupanga nsalu za polyester ndi viscose kumafuna kukhazikitsidwa kogwirizana kwa njira zingapo, kugwiritsa ntchito kuwongolera mosamalitsa kukulitsa mphamvu zowonjezera za ulusiwo, pamapeto pake kumapangitsa kuti nsaluyo ikhale yopangidwa ndi nsalu yomwe imaphatikiza magwiridwe antchito ndi chitonthozo.
