Ngenxa yezici zayo zemvelo ezinhle kakhulu, isetshenziswa kabanzi ekukhiqizeni izidingo zansuku zonke kanye nemikhiqizo yezimboni, kodwa ngokukhula kwabantu emhlabeni, isidingo sabantu sesikhumba siphindwe kabili, futhi inani elilinganiselwe lesikhumba semvelo sekuyisikhathi eside lingasakwazi ukuhlangabezana nezidingo zabantu. Ukuze kuxazululwe lokhu kuphikisana, ososayensi baqala ukucwaninga nokuthuthukisa isikhumba sokwenziwa kanye nesikhumba sokwenziwa emashumini eminyaka edlule ukuze balungise ukushoda kwesikhumba semvelo. Eminyakeni engaphezu kwengu-50 yomlando wocwaningo inqubo yesikhumba sokwenziwa kanye nesikhumba sokwenziwa esiphonsela inselelo isikhumba semvelo.
Ososayensi baqale ngokutadisha nokuhlaziya ukwakheka kwamakhemikhali kanye nesakhiwo sesikhumba semvelo, kusukela endwangwini evarnishwe nge-nitrocellulose, bangena esikhumbeni sokwenziwa se-PVC, okuyisizukulwane sokuqala sesikhumba sokwenziwa. Ngalesi sisekelo, ososayensi benze intuthuko nokuhlola okuningi, okokuqala ukuthuthukiswa kwesisekelo, kulandelwa ukuguqulwa nokuthuthukiswa kwe-resin yokumboza. Ngawo-1970, izindwangu ezingalukiwe zemicu yokwenziwa zavela i-acupuncture, i-bonding kanye nezinye izinqubo, ukuze isisekelo sibe nesigaba esimise okwe-lotus kanye nesimo se-fibre engenalutho, sifinyelele isakhiwo esinezimbobo, esasihambisana nesakhiwo senethiwekhi sesikhumba semvelo. Izidingo: Ngaleso sikhathi, ungqimba olungaphezulu lwesikhumba sokwenziwa lungavele lufinyelele ungqimba lwe-polyurethane olunezimbobo ezincane, olulingana nobuso besikhumba semvelo, ukuze ukubukeka nesakhiwo sangaphakathi sesikhumba sokwenziwa se-PU kusondele kancane kancane kulezo zesikhumba semvelo, kanti ezinye izakhiwo zomzimba ziseduze nezesikhumba semvelo. , futhi umbala ukhanya kakhulu kunesikhumba semvelo; ukumelana kwayo nokugoqa ekushiseni kwegumbi kungafinyelela izikhathi ezingaphezu kwesigidi, futhi ukumelana nokugoqa ekushiseni okuphansi kungafinyelela ezingeni lesikhumba semvelo.
Ngemuva kwesikhumba sokwenziwa se-PVC, isikhumba sokwenziwa se-PU sifinyelele intuthuko yezobuchwepheshe ephumelelayo njengendawo efanelekile yokufaka esikhundleni sesikhumba semvelo ngemuva kweminyaka engaphezu kwengu-30 yocwaningo nentuthuko yochwepheshe besayensi nobuchwepheshe.
Isembozo se-PU ebusweni bendwangu saqala ukubonakala emakethe ngawo-1950, kwathi ngo-1964, iDuPont yasungula isikhumba sokwenziwa se-PU sezingubo zangaphansi zezicathulo. Ngemva kweminyaka engaphezu kwengu-20 yocwaningo oluqhubekayo nentuthuko, isikhumba sokwenziwa se-PU sikhule ngokushesha maqondana nekhwalithi yomkhiqizo, ukuhlukahluka kanye nomkhiqizo. Ukusebenza kwaso kusondela kakhulu esikhumbeni semvelo, kanti ezinye izakhiwo zidlula ngisho nesikhumba semvelo, zifinyelela ezingeni elingahlukaniseki esikhumbeni semvelo, futhi zithatha indawo ebaluleke kakhulu empilweni yomuntu yansuku zonke.
Isikhumba esenziwe nge-microfiber polyurethane siyisizukulwane sesithathu sesikhumba sokwenziwa esivele emakethe yasekhaya nakwamanye amazwe. Indwangu engalukiwe yenethiwekhi yayo yesakhiwo esinezinhlangothi ezintathu idala izimo zokuba isikhumba sokwenziwa sidlule isikhumba semvelo ngokwe-substrate. Lo mkhiqizo uhlanganisa ukufakwa kwe-PU slurry okusha okuthuthukisiwe nesakhiwo se-open-pore kanye nobuchwepheshe bokucubungula ungqimba oluhlanganisiwe, olusebenzisa indawo enkulu ebusweni kanye nokumuncwa kwamanzi okunamandla kwezintambo ezinhle kakhulu, okwenza isikhumba esenziwe nge-superfine PU esinobukhulu obuphezulu ne-bundled superfine. Izakhiwo ze-hygroscopic zesikhumba semvelo sezintambo ze-collagen zingaqhathaniswa nesikhumba semvelo sezinga eliphezulu ngokwesakhiwo sangaphakathi, ukubukeka, ukuthungwa kanye nezakhiwo zomzimba, kanye nenduduzo yabantu abagqoka. Ngaphezu kwalokho, isikhumba esenziwe nge-microfiber sidlula isikhumba semvelo ngokumelana namakhemikhali, ukufana kwekhwalithi, ukukhiqizwa okukhulu kanye nokuzivumelanisa nezimo, kanye nokumelana nokungangeni manzi kanye nokubola.
Umkhuba ufakazele ukuthi izakhiwo ezinhle kakhulu zesikhumba sokwenziwa azinakufakwa esikhundleni sesikhumba semvelo. Kusukela ekuhlaziyweni kwezimakethe zasekhaya nezangaphandle, isikhumba sokwenziwa siphinde safaka esikhundleni inani elikhulu lesikhumba semvelo ngezinsiza ezinganele. Ukusetshenziswa kwesikhumba sokwenziwa kanye nesikhumba sokwenziwa njengokuhlobisa imithwalo, izingubo, izicathulo, izimoto kanye nefenisha kuye kwaqashelwa kakhulu yimakethe.
Isikhumba sikaBoze- Singumsabalalisi kanye noMhwebi Wesikhumba oneminyaka engu-15+ oseDolobheni laseDongguan, eSifundazweni saseGuangdong eShayina. Sihlinzeka ngesikhumba se-PU, isikhumba se-PVC, isikhumba se-microfiber, isikhumba se-silicone, isikhumba esiphinde sasetshenziswa kanye nesikhumba sokwenziwa kuzo zonke izihlalo, amasofa, izikhwama zesandla kanye nezicathulo ngezigaba ezikhethekile ku-Izingubo zokugqoka, Ukungenisa Izihambi/Inkontileka, Ukunakekelwa Kwezempilo, Ifenisha Yehhovisi, Ezasolwandle, Ezezindiza kanye Nezimoto.
