Yuav ua li cas paub qhov txawv ntawm PU thiab tawv hnab?

1, Ua ntej, cov khoom ntawm qis dermis thiab PU tau qhia:

Cov tawv tiag tiag: tawv siv ntaub npuag ua los ntawm cov tawv nqaij tsiaj tom qab ua tiav.

Qhov zoo: A muaj zog toughness

B Hnav tsis kam

C Zoo huab cua permeability

Disadvantages: Ib qhov hnyav (ib cheeb tsam)

Cov khoom xyaw B yog cov protein, yooj yim rau o thiab deform thaum nqus dej

Artificial tawv (PU tawv): Nws yog tsim los ntawm siab elastic fiber ntau, nrog cov yam ntxwv zoo sib xws ntawm tawv.

Qhov zoo: A yog lub teeb hauv qhov hnyav

B Muaj zog toughness

C tuaj yeem ua rau ua pa zoo sib xws

D Waterproof

E Dej nqus dej tsis yooj yim rau nthuav thiab deform

F Kev tiv thaiv ib puag ncig

2, Thib ob, ib qho ntawm txoj hauv kev yooj yim tshaj plaws kom paub qhov txawv ntawm cov hnab tawv nqaij los ntawm lub hnab PU yog qhov hnyav ntawm lub hnab * (cov kev paub hauv qab no tsuas yog rau cov hnab mos xwb, tshwj tsis yog cov hnab ntim khoom siv)

1. Nyhav.Vim tias muaj qhov sib txawv loj ntawm cov tawv nqaij thiab PU, tag nrho cov tawv nqaij yog li ob zaug hnyav li PU.Yog tias ob lub hnab ntawm tib yam style thiab xim raug muab tso rau ntawm tes, tawv tawv hnyav dua li PU.

2. Tes hnov.Nyob rau hauv cov ntaub ntawv ntawm cov tawv tiag tiag, nyuj tawv yog ntau softer dua yaj tawv.Tab sis yog tias nws yog PU, nws yuav softer dua li sheepskin.

Yog hais tias nws yog ib lub hnab tiav, lob cov tawv ntawm lub hnab thiab xav tias nws.Koj yuav pom tias cov tawv ntawm lub hnab tawv tawv yuav tuab heev thaum koj kov nws, thaum lub hnab PU yuav nyias heev.

3. Luam tawm.Qhov kev vam meej ntawm txoj kev no tsuas yog 80%.Txoj kev no tsuas yog siv los ua kev siv xwb.Tsis tas li ntawd, tib neeg tsis muaj ntau lub sijhawm los sim nws thaum yuav cov hnab tawv.Txoj hauv kev tseem ceeb yog nias koj cov ntiv tes rau ntawm daim tawv nqaij thiab pom lub sijhawm uas cov ntsia hlau luam tawm yuav zoo.Yog tias qhov kev rov qab sai sai, cov ntsia hlau luam tawm yuav luag ploj.Tom qab ntawd cov tawv yog ua los ntawm PU.Yog tias qhov rov qab qeeb, nws yog tawv tawv.

4. Kho vajtse.Qhov no yog ib txoj hauv kev rau cov neeg tsim khoom lag luam kom yooj yim paub qhov txawv ntawm tawv ntawm PU, uas yog, saib cov khoom siv kho vajtse.(Cov khoom siv hu ua khoom siv yog hais txog cov khoom siv hlau ntawm lub hnab, xws li lub voj voog, buckles, square buckles, thiab lwm yam.) Feem ntau, cov hnab tawv yog ua los ntawm cov tawv tiag tiag vim yog cov nqi siab ntawm lawv cov ntaub ntawv tawv, yog li lawv xav tau. kom muaj nuj nqis, manufacturers yuav xaiv cov khoom siv tuag-casting (alloy hardware luv luv).Tsis muaj qhov tawg ntawm qhov chaw, thiab kev kho deg yog du heev, nyob rau hauv ib lo lus: high-end.Cov cuab yeej siv ntawm PU yuav tsis yog qhov tshwj xeeb.Ua ntej, cov khoom siv ntawm PU yuav tsis xeb thiab ploj vim yog acidity ntawm PU, thiab cov khoom siv ntawm PU yog cov hlau hlau (lub npe hu ua hlau hlau zoo li cov hlau hlau sib tw rau hauv cov duab sib txawv, thiab qhov saum npoo tuaj yeem pom tseeb. lub cim tawg)

5. Saib tag.Feem ntau, cov hnab ntim tau nruab nrog cov cim npe.Lub cim yog dai ntawm lub hnab tom qab lub ntsiab tawv pwm yog nias.Thaum koj yuav ib lub hnab, lub cim npe feem ntau tsis muaj txiaj ntsig, yog li koj tuaj yeem siv lub teeb los hlawv nws.Yog tias nws tsis hlawv thiab saj zoo li cov protein, nws yog ua los ntawm nyuj tawv.Yog tias nws yaj thaum nws hlawv, nws yog cov khoom siv.Qhov no yog qhov tseem ceeb tshaj plaws thiab siv tau zoo.

6. Lub hnab ntim khoom tshiab, vim yog kev ua haujlwm, yuav muaj qee yam tsis hnov ​​tsw (roj ntug, kua nplaum, thiab lwm yam) yog tias cov khoom xa tuaj ceev, uas yog ib txwm muaj;Ntxiv nrog rau cov ntxhiab tsw zoo li no, qhib lub hnab, tig cov tawv nqaij sab hauv, thiab ua tib zoo mloog.Yuav muaj ntxhiab tsw ntawm cowhide.Qhov no yog cowhide;Yog tias nws yog tawv nqaij yaj, nws yog tawv yaj.Ostrich tawv nqaij, khej tawv, thiab lwm yam
