Hais txog Acetate Fiber

Lub Chemical Properties ntawm Acetate Fiber

1.Alkali tsis kam

Tsis muaj zog alkaline tus neeg sawv cev yuav luag tsis muaj kev puas tsuaj rauacetate fiber ntau, yog li cov fiber ntau poob qis heev. Yog hais tias nyob rau hauv muaj zog alkali, acetate fiber, tshwj xeeb tshaj yog cov diacetate fiber, yog ib qho yooj yim kom muaj deacetylation, uas ua rau kom poob phaus thiab txo lub zog thiab modulus. Yog li, pH tus nqi ntawm cov tshuaj rau kev kho mob acetate fiber yuav tsum tsis txhob siab tshaj 7.0. Nyob rau hauv tus txheej txheem ntxhua khaub ncaws, acetate fiber ntau muaj zog chlorine bleaching kuj. Nws tuaj yeem ua kom qhuav los ntawm perchloroethylene.

2.Resistance rau cov kuab tshuaj organic

Acetate fiber tuaj yeem ua tiav hauv acetone, DMF thiab glacial acetic acid thiab nws tsis tuaj yeem soluble hauv ethyl cawv lossis tetrachloroethylene. Raws li cov khoom no, acetone tuaj yeem siv los ua qhov hnyav hnyav rau acetate fiber. Thiab acetate fiber tuaj yeem qhuav ntxuav los ntawm tetrachloroethylene.

3.Acid tsis kam

Acetate fiber yog ruaj khov hauv cov kua qaub. Feem ntau sulfuric acid, hydrochloric acid thiab nitric acid, yog hais tias nyob rau hauv ib tug tej yam concentration ntau yam, lawv yuav tsis cuam tshuam lub zog, luster los yog elongation ntawm acetate fiber. Tab sis acetate fiber yog soluble hauv concentrated sulfuric acid, concentrated hydrochloric acid thiab concentrated nitric acid.

4.Dyeing khoom

Disperse dyes yog cov xim zoo tshaj plaws rau acetate fiber, uas muaj qhov hnyav molecular thiab zoo sib xws.dyeingtus nqi.

Cov acetate fiber los yog ntaub dyed los ntawm disperse dyes muaj xim ci, ci ntsa iab luster, zoo leveling nyhuv, siab dye-uptake tus nqi, zoo xim ceev thiab qus chromatogram.

Lub cev muaj zog ntawm Acetate Fiber

1.Acetate fiber ntau muaj qee qhov nqus dej. Nws kuj tseem muaj cov cuab yeej ua kom lub cev qhuav dej sai sai tom qab dej adsorbing.

2.Acetate fiber ntau muaj cua sov zoo. Cov iav hloov pauv kub ntawm acetate fiber ntau yog li 185 ℃ thiab qhov kub ntawm qhov kub yog li 310 ℃. Thaum qhov kub tsis nce, qhov poob qis ntawm fiber ntau yog 90.78%. Lub zog tawg hloov ntawm 1.29 cN / dtex mus rau 31.44%.

3.Qhov ceev ntawm acetate fiber yog me dua li ntawm viscose fiber ntau thiab nws zoo ib yam li polyester. Lub zog yog qhov tsawg tshaj plaws ntawm peb fibers.

4.Qhov elasticity ntawm acetate fiber yog qhov zoo, uas yog ze rau ntawm cov ntaub lo lo ntxhuav thiab ntaub plaub.

5.Shrinkage nyob rau hauv boiling dej yog tsawg. Tab sis kev kub siab ua haujlwm yuav cuam tshuam lub zog thiab luster. Yog li qhov kub tsis tuaj yeem tshaj 85 ℃.

Puas yog acetate fiber ntau xis rau hnav?

1.Diacetate fiber ntau muaj huab cua permeability zoo thiab cov khoom tiv thaiv zoo li qub.

Nyob rau hauv ib puag ncig ntawm 65% txheeb ze av noo, diacetate fiber muaj tib yam noo noo nqus raws li paj rwb thiab zoo dua kom qhuav sai dua li paj rwb. Yog li nws tuaj yeem nqus cov dej vapor evaporating los ntawm tib neeg lub cev thiab tom qab ntawd tso tawm tau zoo, uas ua rau tib neeg nyiam. Nyob rau tib lub sijhawm, qhov ua tau zoo ntawm kev nqus dej noo tuaj yeem txo qhov sib xyaw ntawm cov hluav taws xob zoo li qub.

2. Diacetate fiber muaj moskov.

Yog tias qhov pib modulus qis, nyob rau hauv cov khoom me me, cov fibers tsis muaj zog thiab hloov tau yooj yim. Yog li ntawd nws qhia tau hais tias qhov kev ua tau zoo ntawm cov mos mos, uas ua rau cov tawv nqaij muaj qhov muag thiab du.

Yog hais tias qhov pib modulus siab, nyob rau hauv me me loads, lub fiber yog nruj thiab unbending. Yog li nws qhia kev ua haujlwm nruj.

3. Diacetate fiber ntau muaj kev ua haujlwm zoo deodorizing.

Vim li cas acetate fiber ntau zoo li zoo?

1.Diacateate fiber muaj downy pearly luster.

2.Acetate fiber ntau muaj drapability zoo heev.

3.Diacetate muaj xim ci ntsa iab thiab ci ntsa iab thiab ceev ceev. Nws muaj chromatography qus, tag nrho thiab ntshiab xim ntxoov ntxoo thiab zoo heev xim ceev ceev.

4.Acetate fiber ntau muaj qhov ruaj khov zoo. Nws muaj tsawg expansibility rau dej. Yog li cov ntaub tuaj yeem ua kom zoo qhov ruaj khov.

5.Diacetate fiber ntau muaj qhov sib npaug los tiv thaiv fouling. Nws muaj kev ua haujlwm tiv thaiv staining thiab yooj yim ntxuav kev ua haujlwm rau plua plav, dej stain thiab roj stain.
