Tawv yog ib yam khoom qub tshaj plaws hauv tib neeg keeb kwm. Txij li thaum lub sijhawm prehistoric, tib neeg pib siv tsiaj plaub rau kev kho kom zoo nkauj thiab kev tiv thaiv. Txawm li cas los xij, kev siv tshuab ua tawv tawv thawj zaug yog qhov yooj yim heev, tsuas yog ntub cov tsiaj plaub hauv dej thiab tom qab ntawd ua nws. Nrog rau kev hloov pauv ntawm lub sijhawm, tib neeg tawv tsim tshuab tau maj mam hloov zuj zus thiab txhim kho. Los ntawm thawj txoj kev tsim khoom tsim los rau niaj hnub industrialized ntau lawm, cov ntaub ntawv tawv ua lub luag haujlwm tseem ceeb hauv tib neeg lub neej.
Thaum ntxov tawv manufacturing
Kev tsim tawv tawv thaum ntxov tuaj yeem taug qab mus rau lub sijhawm Egyptian thaum ub nyob ib ncig ntawm 4000 BC. Nyob rau lub sijhawm ntawd, tib neeg tau ntub cov tsiaj plaub hauv dej thiab ua tiav nrog cov roj zaub thiab dej ntsev. Txoj kev tsim khoom no yog qhov tseem ceeb heev thiab tsis tuaj yeem tsim cov khoom siv tawv zoo. Tsis tas li ntawd, kev ua haujlwm ntau thiab sijhawm yuav tsum tau ua hauv cov txheej txheem tsim khoom. Txawm li cas los xij, vim muaj zog toughness thiab durability ntawm cov ntaub ntawv tawv, lawv tau dav siv nyob rau hauv ancient haiv neeg los ua khaub ncaws, khau, handbags thiab lwm yam khoom.
Nrog rau cov kev hloov ntawm lub sij hawm, tib neeg tawv manufacturing technology kuj maj mam tsim. Nyob ib ncig ntawm 1500 BC, cov neeg Greek thaum ub tau pib siv tshuab tanning los ua cov tsiaj plaub los tsim cov ntaub ntawv tawv thiab tawv dua. Lub hauv paus ntsiab lus ntawm tanning thev naus laus zis yog siv cov ntaub ntawv tanning los hla kev txuas cov collagen hauv cov tsiaj plaub, ua rau nws mos, dej-resistant, corrosion-resistant thiab lwm yam khoom. Txoj kev tsim khoom no tau siv dav hauv Middle East thiab Europe thaum ub thiab tau los ua txoj hauv kev tseem ceeb ntawm kev tsim tawv tawv thaum ub.
Kev tsim cov tawv tawv tiag tiag
Cov tawv tiag tiag yog hais txog cov khoom tawv tawv uas ua los ntawm cov tsiaj plaub. Kev tsim tshuab ntawm cov tawv tawv tiag tiag yog qhov siab dua thiab nyuaj dua li ntawm cov tawv tawv thaum ntxov. Cov txheej txheem tseem ceeb ntawm kev tsim cov tawv nqaij muaj xws li: stripping tsiaj plaub, soaking, ntxuav, tanning, dyeing thiab ua. Ntawm lawv, tanning thiab dyeing yog cov kauj ruam tseem ceeb tshaj plaws hauv kev tsim cov tawv tiag tiag.
Nyob rau hauv cov txheej txheem tanning, feem ntau siv tanning cov ntaub ntawv muaj xws li zaub tanning cov ntaub ntawv, chrome tanning cov ntaub ntawv thiab hluavtaws tanning khoom. Ntawm lawv, chrome tanning cov ntaub ntawv tau dav siv vim lawv qhov zoo xws li kev ua haujlwm ceev ceev, ruaj khov zoo thiab cov txiaj ntsig zoo. Txawm li cas los xij, cov dej khib nyiab thiab cov khoom pov tseg uas tsim tawm thaum lub sij hawm chrome tanning yuav ua phem rau ib puag ncig, yog li lawv yuav tsum tau kho thiab tswj kom tsim nyog.
Thaum lub sij hawm dyeing txheej txheem, cov tawv tiag tuaj yeem dyed nyob rau hauv cov xim sib txawv raws li xav tau kom ua tiav cov hniav sib txawv thiab kev tiv thaiv. Ua ntej dyeing, cov tawv tiag tiag yuav tsum tau kho qhov chaw kom cov xim tuaj yeem nkag mus thiab kho ntawm tawv tawv. Tam sim no, hom thiab qhov zoo ntawm cov dyes tau txhim kho tas li, uas tuaj yeem ua tau raws li tib neeg cov kev xav tau sib txawv thiab nyiam rau cov ntaub ntawv tawv.
Kev tsim khoom ntawm PU thiab PVC tawv
Nrog rau kev txhim kho txuas ntxiv ntawm cov cuab yeej siv tshuaj, tib neeg tau maj mam nrhiav pom qee cov khoom siv hluavtaws tshiab uas tuaj yeem simulate cov tsos thiab kev xav ntawm cov tawv tiag tiag, thiab muaj cov yas zoo dua, tsis muaj dej thiab ua kom ntev. Cov khoom siv hluavtaws no feem ntau suav nrog PU (polyurethane) tawv thiab PVC (polyvinyl chloride) tawv.
PU tawv yog cov tawv simulated ua los ntawm cov khoom siv polyurethane, uas muaj cov yam ntxwv ntawm softness, dej tsis kam, hnav tsis kam thiab tsim kua muag. Nws txoj kev tsim khoom yog los npog cov khoom siv polyurethane ntawm cov khoom siv fiber ntau lossis cov khoom tsis-woven, thiab tsim cov khoom siv tawv tom qab calendering, tanning, dyeing thiab lwm yam txheej txheem. Piv nrog cov tawv tiag tiag, PU tawv muaj qhov zoo ntawm tus nqi qis thiab kev ua haujlwm yooj yim, thiab tuaj yeem simulate ntau yam xim thiab kev ntxhib los mos. Nws yog dav siv hauv kev tsim cov khaub ncaws, khau, rooj tog thiab lwm yam khoom.
PVC tawv yog ib hom simulated tawv ua los ntawm polyvinyl chloride cov khoom, uas muaj cov yam ntxwv ntawm waterproof, hnav-resistant thiab yooj yim los ntxuav. Nws txoj kev tsim khoom yog los txheej cov khoom siv polyvinyl chloride rau ntawm lub substrate, thiab tom qab ntawd tsim cov khoom siv tawv los ntawm calendering, engraving, dyeing thiab lwm yam txheej txheem. Piv nrog PU tawv, PVC tawv muaj qhov zoo ntawm tus nqi qis thiab muaj zog toughness, thiab tuaj yeem simulate ntau yam xim thiab qauv. Nws yog dav siv hauv kev tsim cov rooj zaum hauv tsheb, lub nra, hnab tes thiab lwm yam khoom.
Txawm hais tias PU thiab PVC tawv muaj ntau qhov zoo, lawv tseem muaj qee qhov tsis zoo. Piv txwv li, lawv cov txheej txheem tsim khoom yuav tsim cov pa phem ntau thiab cov dej khib nyiab, uas yuav ua rau ib puag ncig. Tsis tas li ntawd, lawv lub neej tsis ntev npaum li cov tawv tawv tiag tiag, thiab lawv yooj yim ploj mus thiab hnub nyoog. Yog li ntawd, tib neeg yuav tsum tau ua tib zoo saib xyuas thiab saib xyuas thaum siv cov khoom siv tawv hluavtaws.
Kev tsim khoom ntawm silicone tawv
Ntxiv nrog rau cov tawv tawv thiab hluavtaws tawv, ib hom tshiab ntawm cov khoom siv tawv, silicone tawv, tau tshwm sim nyob rau hauv xyoo tas los. Silicone tawv yog cov tawv tawv ua los ntawm cov khoom siv silicone siab molecular thiab cov khoom siv fiber ntau txheej, uas muaj qhov zoo ntawm lub teeb yuag, folding tsis kam, tiv thaiv kev laus, tsis muaj dej, tiv thaiv fouling thiab yooj yim los ntxuav, thiab tawv nqaij thiab xis nyob.
Silicone tawv muaj ntau yam kev siv thiab tuaj yeem siv los ua lub tsheb sab hauv, hnab tes, xov tooj ntawm tes thiab lwm yam khoom. Piv nrog PU thiab PVC tawv, silicone tawv tau zoo dua hydrolysis tsis kam, UV tsis kam, ntsev tsuag kuj thiab kub thiab kub tsis kam, thiab tsis yooj yim rau hnub nyoog thiab ploj. Tsis tas li ntawd, tsis muaj cov pa phem thiab cov dej khib nyiab raug tsim thaum lub sij hawm tsim cov txheej txheem ntawm silicone tawv, thiab cov pa phem rau ib puag ncig kuj tsawg dua.

Raws li cov khoom qub thiab fashionable, tawv tau dhau los ntawm txoj kev loj hlob ntev. Los ntawm thawj zaug tsiaj plaub ua rau cov tawv nqaij niaj hnub, PU, PVC tawv thiab silicone tawv, hom thiab zoo ntawm tawv tau raug txhim kho tsis tu ncua, thiab cov peev txheej ntawm daim ntawv thov tau txuas ntxiv nthuav dav. Txawm hais tias nws yog tawv tawv lossis hluavtaws tawv, nws muaj nws tus kheej qhov zoo thiab qhov tsis zoo, thiab tib neeg yuav tsum xaiv raws li qhov xav tau sib txawv thiab cov xwm txheej thaum siv nws.
Txawm hais tias niaj hnub siv tshuab thiab cov khoom siv tshuaj lom neeg tau hloov ntau txoj kev ua tawv tawv, tawv tiag tiag tseem yog cov khoom muaj txiaj ntsig, thiab nws cov kev xav thiab kev ntxhib los mos ua rau nws thawj qhov kev xaiv rau cov khoom siv high-end. Nyob rau tib lub sijhawm, tib neeg tau maj mam paub txog qhov tseem ceeb ntawm kev tiv thaiv ib puag ncig thiab pib sim siv cov ntaub ntawv zoo ib puag ncig thiab ruaj khov los hloov cov tawv hluavtaws tawv. Silicone tawv yog ib qho ntawm cov ntaub ntawv tshiab. Nws tsis tsuas yog muaj kev ua tau zoo heev, tab sis kuj muaj cov pa phem tsawg rau ib puag ncig. Nws tuaj yeem hais tias yog ib qho khoom cog lus heev.
Nyob rau hauv luv luv, nrog kev nce qib ntawm kev tshawb fawb thiab thev naus laus zis thiab tib neeg kev mloog rau kev tiv thaiv ib puag ncig, tawv, cov khoom qub thiab cov khoom siv niaj hnub, kuj tseem niaj hnub hloov kho thiab txhim kho. Seb nws yog tawv tiag tiag, PU, PVC tawv, los yog silicone tawv, nws yog crystallization ntawm tib neeg txoj kev txawj ntse thiab kev ua haujlwm nyuaj. Kuv ntseeg tias yav tom ntej txoj kev loj hlob, cov ntaub ntawv tawv yuav txuas ntxiv hloov tshiab thiab hloov pauv, coj kev zoo nkauj thiab yooj yim rau tib neeg lub neej.
