Ngenxa yokuqina kwayo kunye nenkangeleko yeklasikhi, ulusu luhlala luthandwa kakhulu kwifashoni, ifenitshala kunye nezixhobo. Kwiminyaka yakutshanje, nangona kunjalo, umntu omtsha okhuphisana naye uye wavela kwi-PU yesikhumba. Kodwa yintoni kanye kanye PU ngesikhumba? Yahluke njani kwithwathwa lokwenyani? Kweli nqaku, siza kuntywila kwiimpawu kunye nomahluko phakathi kwezi zimbini.
PU ngesikhumba, ekwaziwa njenge sikhumba sokwenziwa okanye i-faux leather, imele ufele lwe-polyurethane. Yimpahla yokwenziwa efana nenkangeleko kunye nokuziva kwesikhumba sokwenyani. Ngokungafaniyo nesikhumba sokwenyani, esenziwe kwizikhumba zezilwanyana, i-PU yesikhumba yenziwe ngokudibanisa i-polyurethane coatings esetyenziswe kwizinto ezisisiseko (ngokuqhelekileyo indwangu efana ne-polyester okanye ikotoni). Olu tyaba ludala ukuthungwa okufana kakhulu nesikhumba sokwenyani.
Enye yeenzuzo eziphambili ze-PU yesikhumba kukufikeleleka kwayo.Ngenxa yenkqubo yokuvelisa kunye nokungabikho kwezikhumba zezilwanyana, i-PU yesikhumba ingabizi kakhulu ukuvelisa kunesikhumba sangempela. Oko kwenza kube lukhetho oluphezulu kwabo bafuna inkangeleko entle kunye nokuziva kwesikhumba ngaphandle kokuhlawula ithegi yexabiso elikhulu.
Ukongeza, i-PU yesikhumba inokumelana okuphezulu kwamanzi kunye nokumelana nomkrwelo xa kuthelekiswa nesikhumba sokwenyani. Ngokuqhelekileyo kuthathwa njengento ehlala ixesha elide kwaye kulula ukuyigcina njengoko inokucocwa ngelaphu elimanzi. Ulusu lokwenyani, kwelinye icala, lufuna ukhathalelo olukhethekileyo kunye nokulungiswa ukuze lugcinwe lukhangeleka lungcono.
Nangona kunjalo, kukho umahluko omkhulu phakathi kwesikhumba sePU kunye nesikhumba sokwenyani. Umahluko ophawulekayo kukubunjwa kwazo. Isikhumba sokwenyani siphuma kwisikhumba sesilwanyana kwaye siyinto yendalo. Ineempawu ezizodwa ezifana nokuphefumla, ukuguquguquka kunye nobudala ngobuhle ngokuhamba kwexesha. Isiqwenga ngasinye sesikhumba sokwenyani sineempawu ezikhethekileyo, zongeza umtsalane nobuntu.
Ngokwahlukileyo, isikhumba sePU asinazo ezi mpawu zendalo. Ayiphefumli kwaye ayiziva ithambile xa ithelekiswa nesikhumba sokwenyani. Ngokuhamba kwexesha, isikhumba sePU sinokubonisa iimpawu zokukrazuka okanye ukuxobuka ekunxibeni. Ngesikhumba sokwenyani, oku akuyongxaki njengoko iphuhlisa ipatina eyandisa ukukhanga kwayo kunye nokuqina.
Olunye uqwalaselo olubalulekileyo xa ukhetha phakathi kwesikhumba sePU kunye nesikhumba sokwenyani kukuzinza. Isikhumba se-PU sisoloko sithathwa ngokuba sinobuhlobo nendalo esingqongileyo kuba ayifuni zikhumba zezilwanyana. Inokwenziwa ngendlela elawulwayo nezinzileyo. Nangona kunjalo, isikhumba sangempela siphakamise inkxalabo malunga nentlalontle yezilwanyana kunye nefuthe lokusingqongileyo kwishishini lenyama.
Ukuqukumbela, i-PU yesikhumba yenye indlela yokwenziwa kwesikhumba sokwenyani eyenzelwe ukulinganisa inkangeleko kunye nokuthungwa kwayo. Iyafikeleleka, ayinamanzi kwaye kulula ukuyigcina. Kwelinye icala, isikhumba sokwenyani sineempawu ezikhethekileyo njengokuphefumla nokuguga okuthandekayo. Ekugqibeleni, ukhetho phakathi kwezi zibini luhla kukhetho lomntu, uhlahlo lwabiwo-mali, kunye neengqwalasela zokuziphatha.
