Cov txheej txheem thiab txheej txheem ntawm cov tawv nqaij, polyurethane (PU) microfiber hluavtaws tawv thiab polyvinyl chloride (PVC) hluavtaws tawv tau muab piv, thiab cov khoom siv tau raug kuaj, piv thiab tshuaj xyuas. Cov txiaj ntsig tau pom tias nyob rau hauv cov ntsiab lus ntawm kev siv tshuab, kev ua tau zoo ntawm PU microfiber hluavtaws tawv yog zoo dua li cov tawv tawv thiab PVC hluavtaws tawv; Nyob rau hauv cov nqe lus ntawm dabtsi yog khoov kev ua tau zoo, kev ua tau zoo ntawm PU microfiber hluavtaws tawv thiab PVC hluavtaws tawv yog zoo sib xws, thiab kev khoov kev ua tau zoo yog zoo dua li cov tawv tiag tiag tom qab kev laus hauv ntub dej kub, kub kub, kev hloov pauv huab cua, thiab qhov kub thiab txias; Nyob rau hauv cov nqe lus ntawm hnav tsis kam, hnav thiab tsim kua muag kuj ntawm PU microfiber hluavtaws tawv thiab PVC hluavtaws tawv yog zoo dua li cov tawv tawv; Nyob rau hauv cov nqe lus ntawm lwm yam khoom siv, cov dej vapor permeability ntawm cov tawv tiag, PU microfiber hluavtaws tawv thiab PVC hluavtaws tawv txo qis, thiab qhov seem stability ntawm PU microfiber hluavtaws tawv thiab PVC hluavtaws tawv tom qab thermal aging yog zoo sib xws thiab zoo dua li cov tawv tawv.
Raws li ib feem tseem ceeb ntawm lub tsheb sab hauv, lub rooj zaum hauv tsheb ncaj qha cuam tshuam rau tus neeg siv kev tsav tsheb. Cov tawv nqaij, polyurethane (PU) microfiber hluavtaws tawv (tom qab no hu ua PU microfiber tawv) thiab polyvinyl chloride (PVC) hluavtaws tawv yog txhua yam siv rooj zaum ntaub.
Ntuj tawv muaj keeb kwm ntev ntawm daim ntawv thov hauv tib neeg lub neej. Vim muaj cov tshuaj lom neeg thiab triple helix qauv ntawm collagen nws tus kheej, nws muaj qhov zoo ntawm softness, hnav tsis kam, siab zog, siab nqus dej thiab dej permeability. Natural tawv feem ntau yog siv rau hauv lub rooj zaum fabrics ntawm nruab nrab-rau-high-end qauv hauv kev lag luam automotive (feem ntau cowhide), uas tuaj yeem muab cov khoom kim heev thiab kev nplij siab.
Nrog rau txoj kev loj hlob ntawm tib neeg lub neej, cov khoom ntawm cov tawv nqaij yog qhov nyuaj rau kev ua kom tau raws li cov neeg xav tau kev loj hlob. Tib neeg tau pib siv cov khoom siv tshuaj lom neeg thiab cov hau kev los hloov cov tawv nqaij, uas yog, tawv hluavtaws tawv. Lub advent ntawm PVC hluavtaws tawv tuaj yeem taug qab mus rau 20th Xyoo 1930s, nws yog thawj tiam ntawm cov khoom tawv tawv. Nws cov yam ntxwv ntawm cov khoom muaj zog, hnav tsis kam, folding kuj, acid thiab alkali tsis kam, thiab lwm yam, thiab nws yog tus nqi qis thiab yooj yim rau kev ua. PU microfiber tawv tau ua tiav hauv xyoo 1970s. Tom qab kev nce qib thiab kev txhim kho ntawm kev siv thev naus laus zis niaj hnub no, raws li hom tshiab ntawm cov khoom siv hluavtaws tawv, nws tau siv dav hauv cov khaub ncaws high-end, rooj tog zaum, pob, tsheb sab hauv thiab lwm yam. Cov yam ntxwv ntawm cov khoom siv ntawm PU microfiber tawv yog tias nws simulates cov qauv sab hauv thiab kev ntxhib los mos zoo ntawm cov tawv nqaij, thiab muaj kev ruaj khov zoo dua li tawv tawv, ntau cov khoom siv tau zoo thiab kev phooj ywg ib puag ncig.

Folding kuj
Cov xeev ntawm cov qauv folding kuj tau muab faib ua 6 hom, uas yog lub xeev pib (tsis muaj lub xeev), damp tshav kub laus lub xeev, tsis tshua muaj kub xeev (-10 ℃), xenon lub teeb laus lub xeev (PV1303/3P), kub kub aging xeev (100 ℃ / 168h) thiab climate alternation aging xeev (PV12 00/2). Txoj kev folding yog siv tawv dabtsi yog khoov ntsuas los kho ob qhov kawg ntawm cov qauv duab plaub nyob rau hauv qhov ntev ntawm cov kev taw qhia ntawm lub ntsuas phoo thiab qis, kom cov qauv yog 90 °, thiab rov khoov ntawm qee qhov ceev thiab lub kaum ntse ntse. Cov ntaub ntawv folding kev ua tau zoo ntawm cov tawv tawv, PU microfiber tawv thiab PVC hluavtaws tawv tau pom nyob rau hauv Table 3. Nws tuaj yeem pom los ntawm Table 3 tias cov tawv tawv tiag tiag, PU microfiber tawv thiab PVC hluavtaws tawv qauv yog tag nrho cov ntaub qhwv tom qab 100,000 zaug hauv thawj lub xeev thiab 10,000 zaug hauv lub xeev laus nyob rau hauv xenon teeb. Nws tuaj yeem tuav lub xeev zoo yam tsis muaj kab nrib pleb lossis kev ntxhov siab ua kom dawb. Hauv lwm lub xeev kev laus sib txawv, uas yog, lub xeev ntub dej kub, lub xeev kub kub, thiab kev hloov pauv huab cua ntawm PU microfiber tawv thiab PVC hluavtaws tawv, cov qauv tuaj yeem tiv taus 30,000 bending xeem. Tom qab 7,500 mus rau 8,500 kev sim khoov, cov kab nrib pleb lossis kev ntxhov siab tau pib tshwm rau hauv lub xeev ntub dej kub laus thiab kub kub laus lub xeev cov qauv ntawm cov tawv tiag, thiab qhov hnyav ntawm cov tawv nqaij ntub dej (168h / 70 ℃ / 75%) yog qis dua li ntawm PU microfiber tawv. Fiber tawv thiab PVC hluavtaws tawv (240h / 90 ℃ / 95%). Ib yam li ntawd, tom qab 14,000 ~ 15,000 qhov kev sim khoov, cov kab nrib pleb lossis kev ntxhov siab yuav tshwm sim nyob rau hauv lub xeev ntawm cov tawv nqaij tom qab huab cua hloov pauv kev laus.

Qhov sib txawv tseem ceeb hauv cov ntaub ntawv xeem yog dej permeability thiab qhov me me shrinkage. Cov dej permeability ntawm tawv yog ze li ob npaug ntawm PU microfiber tawv, thaum PVC hluavtaws tawv yuav luag tsis muaj dej permeability. Qhov no yog vim hais tias peb-dimensional network skeleton (non-woven npuag) nyob rau hauv PU microfiber tawv zoo ib yam li lub ntuj pob khoom collagen fiber qauv ntawm tawv, ob qho tib si uas muaj microporous lug, ua rau ob leeg muaj tej yam dej permeability. Tsis tas li ntawd, qhov chaw hla ntawm cov collagen fibers hauv tawv yog loj dua thiab sib npaug sib npaug, thiab qhov kev faib ua feem ntawm qhov chaw microporous yog ntau dua li ntawm PU microfiber tawv, yog li tawv muaj cov dej permeability zoo tshaj plaws. Nyob rau hauv cov nqe lus ntawm qhov me me shrinkage, tom qab tshav kub laus (120 ℃ / 1 Lub shrinkage tus nqi ntawm PU microfiber tawv thiab PVC hluavtaws tawv qauv tom qab tshav kub laus (68h) yog zoo sib xws thiab ho qis dua cov tawv tiag, thiab lawv seem stability yog zoo dua li cov tawv tiag tiag. Tsis tas li ntawd, qhov kev ntsuam xyuas ntawm kab rov tav nplaim hluav taws xob retardancy thiab tawv tawv PU tawv muaj peev xwm qhia tau hais tias cov qauv ntawm cov tawv nqaij thiab cov tawv nqaij ntawm cov tawv nqaij ntawm cov tawv nqaij thiab cov tawv nqaij ntawm cov tawv nqaij ntawm cov tawv nqaij thiab cov tawv nqaij ntawm cov tawv nqaij ntawm cov tawv nqaij thiab cov tawv nqaij ntawm cov tawv nqaij. ncav cuag cov qib zoo sib xws, thiab tuaj yeem ua tau raws li cov qauv kev cai ntawm cov nplaim hluav taws kub hnyiab thiab kev ua haujlwm tsw.
Feem ntau, cov dej vapor permeability ntawm cov tawv tawv, PU microfiber tawv thiab PVC hluavtaws tawv qauv txo qis. Cov nqi shrinkage (stabilization) ntawm PU microfiber tawv thiab PVC hluavtaws tawv tom qab tshav kub laus yog zoo sib xws thiab zoo dua li tawv tawv, thiab kab rov tav nplaim retardancy yog zoo dua li cov tawv tiag. Lub ignition thiab tsw zog yog zoo ib yam.

Cov qauv ntoo khaub lig ntawm PU microfiber tawv zoo ib yam li cov tawv tawv. Cov txheej PU thiab lub hauv paus ntawm PU microfiber tawv sib haum rau cov txheej nplej thiab cov ntaub so ntswg fiber ntau tom kawg. Cov khoom siv qauv ntawm cov txheej ntom ntom ntom txheej, txheej txheem ua npuas dej, cov ntaub nplaum nplaum thiab cov tawv nplaum ntawm PU Microfiber tawv yog pom sib txawv.
Cov khoom zoo ntawm cov tawv nqaij yog tias nws muaj cov khoom siv zoo (lub zog tensile ≥15MPa, elongation ntawm so> 50%) thiab dej permeability. Cov khoom siv zoo ntawm PVC tawv tawv yog hnav tsis kam (tsis muaj kev puas tsuaj tom qab 19,000 lub sij hawm ntawm pob board hnav), thiab nws yog resistant rau ntau yam ib puag ncig. Cov khoom muaj kev ruaj khov zoo (nrog rau kev tiv thaiv kom ya raws thiab cua sov, kub kub, tsis tshua muaj kub, thiab alternating climates) thiab zoo seem stability (smensional shrinkage <5% nyob rau hauv 120 ℃ / 168h). PU microfiber tawv muaj cov khoom zoo ntawm ob qho tib si tawv tawv thiab PVC hluavtaws tawv. Cov txiaj ntsig ntawm cov khoom siv kho tshuab, folding kev ua tau zoo, hnav tsis kam, kab rov tav nplaim retardancy, seem stability, tsw theem, thiab lwm yam tuaj yeem ncav cuag qhov zoo tshaj plaws ntawm cov tawv tawv thiab PVC hluavtaws tawv, thiab tib lub sijhawm muaj qee yam dej permeability. Yog li ntawd, PU microfiber tawv tuaj yeem ua tau raws li daim ntawv thov ntawm cov rooj zaum hauv tsheb thiab muaj cov ntawv thov dav dav.
