Kev faib cov tawv nqaij feem ntau siv hauv kev nyab xeeb khau Tawv yog muab faib ua tawv tawv, tawv tawv thiab tawv tawv.
Ua ntej, tawv. Cov tawv nqaij yog cov tawv nqaij nyoos tev tawm ntawm nyuj, yaj, npua, nees, mos lwj lossis lwm yam tsiaj. Tom qab ua tiav los ntawm lub Hoobkas tawv, nws yog tsim rau hauv cov ntaub ntawv tawv nrog ntau yam ntxwv, lub zog, xav, xim thiab qauv. Nws yog cov khoom siv tawv niaj hnub. Cov ntaub ntawv tseem ceeb. Ntawm lawv, cowhide, sheepskin thiab pigskin yog peb hom tawv tawv siv hauv tanning.
Lub dermis tau muab faib ua ob hom: daim tawv nqaij saum toj kawg nkaus thiab ob txheej ntawm daim tawv nqaij. Nws yog feem ntau siv hauv khau kev nyab xeeb.
(1) Cov tawv nqaij saum toj kawg nkaus yog nyuj, yaj, npua tawv nqaij, thiab lwm yam nrog cov nplais, cov nti thiab cov ntshav nti ntawm cov tawv nqaij, qee zaus muaj cov qhov txhab raug mob thaum ua thiab cov hnyuv uas tsis tshua muaj kev siv. Cov txheej txheej sab saum toj tuaj txawv teb chaws kuj muaj cov lej ntawm cov nyuj. Cov tawv nqaij tag nrho tuaj yeem paub qhov txawv ntawm cov tawv nqaij ntawm qhov pore loj thiab ntom. Muaj ntau ntau hom nyuj nyuj, xws li nyuj hides, nqaij nyuj nyuj, nyuj nyuj, nyuj tawv, nyuj nkaum, nyuj tsis cam khwb cia thiab castrated bull hide. Nyob rau hauv Suav teb, kuj muaj daj cowhide, tawv nyuj, yak tawv thiab yak tawv. Ntawm lawv, lub qhov hws ntawm nyuj yog thicker thiab sparse; tus nyuj daj yog nyias thiab denser tshaj qhov pores ntawm nyuj. Lub qhov hws ntawm cov tawv yaj yog finer thiab denser thiab muaj me ntsis nqes hav. Muaj ob hom tawv yaj thiab tshis tawv nqaij. Txoj cai ntawm pigskin vim cov plaub hau ntev yog faib ntawm 3 ~ 5 cov hauv paus hniav, yog li nws yog ib qho yooj yim kom paub qhov txawv. Feem ntau, pigskins yog tsim los tsim, thiab pigskins qus kuj paub. Cov npuag qus nto moo yog qhov pom tseeb dua. Npua daim tawv nqaij pores thiab grain yam ntxwv, vim nws tshwj xeeb collagen fiber qauv, tuaj yeem ua tiav rau hauv cov ntaub mos mos tawv los yog hnab looj tes tawv tawv, uas yog tus nqi siab. Tsis tas li ntawd, daim tawv nqaij ostrich, crocodile skin, crocodile skin, short-nosed crocodile skin, lizard skin, snake skin, bullfrog skin, seafish skin (shark skin, squid skin, squid skin, squid skin, pearl skin, etc.) (Muaj cov ntses nyom, squid tawv nqaij thiab lwm yam tawv nqaij scaly), tawv hma liab (nyhuv hma tawv nqaij, xiav hma tawv nqaij, thiab lwm yam), hma tawv nqaij, aub tawv nqaij, luav tawv nqaij, thiab lwm yam yog yooj yim txheeb xyuas, thiab ua tsis tau. rau hauv ob txheej tawv nqaij. Thawj txheej ntawm daim tawv nqaij yog ncaj qha ua tiav los ntawm cov tawv nqaij nyoos ntawm ntau yam tsiaj, los yog cov tawv nqaij ntawm nyuj, npua, nees, thiab lwm yam, uas yog thicker nyob rau hauv daim tawv nqaij txheej, yog txiav mus rau hauv ob sab sauv thiab qis khaubncaws sab nraud povtseg. ntawm cov qauv fiber ntau yog ua tiav rau hauv ntau lub taub hau. Txheej tawv nqaij.
(2) Cov txheej thib ob ntawm daim tawv nqaij yog ib txheej xoob ntawm cov qauv fibrous, uas yog ua tiav los ntawm cov tshuaj txau lossis txheej nrog PVC thiab PU zaj duab xis. Nws yog feem ntau siv hauv kev tsim cov khau kev nyab xeeb. Yog li ntawd, ib txoj hauv kev zoo rau kev paub qhov txawv ntawm cov txheej txheem saum toj kawg nkaus thiab txheej thib ob yog saib xyuas cov fiber ntau ntawm qhov ntev ntawm daim tawv nqaij. Cov txheej saum toj kawg nkaus yog tsim los ntawm cov txheej sib dhos thiab nyias nyias txheej thiab muaj lub zog zoo tshaj plaws uas muaj zog, thiab muaj zog zoo, elasticity thiab txheej txheem plasticity. Qhov thib ob txheej ntawm cov tawv nqaij tsuas yog xoob fibrous txheej. Nws tsuas yog siv los ua cov khoom tawv tom qab txau cov khoom siv tshuaj lossis polishing. Nws tuav qee yam ntuj elasticity thiab txheej txheem plasticity, tab sis nws lub zog tsis zoo, thiab nws cov thickness yuav tsum muaj tib txheej. Tib daim tawv nqaij. Kuj tseem muaj ntau hom tawv tawv siv hauv cov khoom siv niaj hnub no. Cov txheej txheem ua tawv tawv yog qhov sib txawv me ntsis, tab sis txoj kev sib txawv yog tib yam.
Qhov thib ob, daim tawv nqaij rov qab: cov tawv nqaij rov tsim dua tshiab yuav raug pulverized nrog ntau yam tsiaj tawv nqaij thiab tawv tawv, thiab tom qab ntawd npaj nrog cov khoom siv tshuaj. Cov txheej txheem txheej txheem saum npoo yog tib yam li cov tawv nqaij, cov tawv nqaij embossed, uas yog tus cwj pwm los ntawm qhov zoo nkauj ntawm daim tawv nqaij, tus nqi siv siab thiab tus nqi qis; tab sis daim tawv nqaij feem ntau yog tuab thiab lub zog tsis zoo, thiab nws tsuas yog tsim nyog rau kev ua lub hnab ntim khoom pheej yig thiab lub hnab trolley. Lub tes tsho zoo li lub pob thiab lwm yam khoom siv tes ua khoom siv thiab cov khoom siv ncaj nraim muaj cov qauv fiber ntau hauv qhov ntev, uas tuaj yeem paub txog cov nyhuv solidification ntawm cov fibers sib xyaw ntawm cov kua dej.
Thib peb, tawv tawv: cov tawv siv rov ua dua tshiab tseem hu ua tawv tawv lossis roj hmab, yog lub npe dav dav rau cov khoom siv dag zog xws li PVC thiab PU. Nws yog ua los ntawm PVC los yog PU foaming los yog laminating rau ntau yam ntaub los yog non-woven fabrics. Nws tuaj yeem ua raws li lub zog sib txawv, hnav tsis kam, txias ua haujlwm thiab xim, luster thiab qauv. Cov qauv thiab cov zoo li yuav tsum tau ua tiav, thiab muaj cov yam ntxwv ntawm ntau yam xim, kev ua haujlwm zoo ntawm cov dej tsis zoo, zoo nkauj ntug dav, siab siv tus nqi thiab tus nqi qis piv nrog tawv. Txawm li cas los xij, feem ntau ntawm cov tawv tawv tsis tuaj yeem muaj cov nyhuv ntawm tawv thiab nws elasticity; nws longitudinal Txiav rau hauv qhov chaw, koj tuaj yeem pom cov npuas me me, daim ntaub lossis daim tawv nqaij zaj duab xis thiab qhuav thiab rayon. Nws yog ib chav kawm ntawm cov ntaub ntawv uas tau nrov heev txij li thaum ntxov thiab feem ntau yog siv los ua ntau yam khoom tawv tawv, lossis cov khoom siv tawv. Nws cov txheej txheem kev tsim khoom nce qib tau siv dav hauv kev ua cov tawv tawv ob txheej. Niaj hnub no, nws zoo li tawv.
