Xov Xwm - Vim li cas cov ntaub acetate kim heev

Ob xyoos dhau los no, cov neeg tsim qauv feem ntau hais tias "acic acid fabric" thiab "triacetic acid fabric", thiab tom qab ntawd lawv yuav 3d voj voog ncig lub suab, "tsis muaj peev xwm them taus!" "Nyob zoo kev tuag! Tsis tuaj yeem siv nws!" Hom ntaub no kuj yog qhov nyiam ntawm cov tuam txhab lag luam siab kawg hauv ob xyoos dhau los, tom qab ntawd nws nyob qhov twg?

Qhia txhua yam khoom qhuav ntawm acetic acid tam sim ntawd, koj nyob qhov twg, thiab thaum lub sijhawm ua qauv khaub ncaws, peb ua cov ntaub acetic acid kim dua? Siv nws kom raug.

1. Cov kua qaub aceticntaub
Acetate fiber yog ib hom fiber dag, yog cov khoom siv semi-synthetic fiber, yog cellulose thiab acetic anhydride reaction kom tau txais fiber acetate, thiab tom qab ntawd spun cellulose acetate fiber tsim. ACETATE fiber, tseem hu ua acetate daim ntaub, uas yog, tib neeg feem ntau hais tias acetic acid ntaub, feem ntau hu ua acetate daim ntaub, tseem hu ua Yasha, yog lus Suav homophone rau lus Askiv acetate.

Acetate fiber muaj peev xwm muab faib ua ob hom acetate fiber thiab peb hom acetate fiber. Qhov txawv ntawm ob thiab peb hom vinegars yog dab tsi?

(1) Peb lub vinegar yog ib hom acetate, tsis muaj hydrolysis, thiab nws qib esterification siab dua. Yog li ntawd, lub teeb thiab cua sov tsis kam yog muaj zog, qhov kev ua haujlwm dyeing tsis zoo, thiab qhov nqus dej noo (tseem hu ua qhov rov qab tau dej noo) qis.
(2) Ob lub vinegar yog ib hom acetate uas tsim los ntawm kev hydrolysis ib nrab, thiab nws qib esterification qis dua li peb lub vinegar. Yog li ntawd, qhov kev ua kom sov tsis zoo li peb lub vinegar, qhov kev ua kom zas xim zoo dua peb lub vinegar, thiab qhov nqus dej noo ntau dua peb lub vinegar.

2. Cov ntaub Triacetic acid
Triacetate feem ntau siv rau hauv peb txoj kev tsim qauv zam. Niaj hnub no, peb tsom mus rau cov ntaub triacetate uas yog cov ntaub zoo acetic acid, yog li triacetate ntxiv rau kim, kim, kim ~ tag nrho lub cev muaj qhov zoo ~

Triacetate, nyob rau hauv lub npe SOALON, yog muab los ntawm cov ntoo conifers uas cog hauv Canada thiab Alaska. Nws yog cov fiber semi-artificial ntshiab, yog tsim los ntawm Nyiv Mitsubishi Rayon Company, ib hom tshiab ntawm cov ntaub ntuj thiab cov thev naus laus zis siab, nrog tib qhov mos li cov fibers ntuj, tab sis nws cov nyhuv zoo ib yam li cov fibers dag.

Acetate fiber nyob rau hauv cov txheej txheem esterification, qib ntawm esterification yog ntau dua 2.7, nws yog hu ua triacetate fiber, thiab cov ntaub ua los ntawm triacetate fiber hu ua triacetate ntaub.

3. PK nrog cov fibers ntuj thiab cov fibers ua los ntawm tib neeg

Qhov tsos thiab ci ntsa iab ntawm cov triacetate fiber zoo ib yam li cov mulberry silk. Qhov kev xav ntawm softness thiab smoothness kuj zoo ib yam li cov mulberry silk, thiab nws qhov hnyav tshwj xeeb yog tib yam li cov mulberry silk, yog li tsis muaj qhov txawv txav hauv qhov qhuav thiab mulberry silk. Qhov yam ntxwv yog tias tus nqi ntawm cov fibers ntuj tau nce siab hauv xyoo tas los no, thiab triacetic acid tau dhau los ua qhov hloov pauv zoo.

Yog li ntawd, tsis muaj qhov txawv txav ntawm cov ntaub thiab cov ntaub txhob lo lo ntxhuav. Tus yam ntxwv yog tias tus nqi ntawm cov ntaub ntuj tau nce siab hauv xyoo tas los no, thiab triacetic acid tau dhau los ua qhov hloov pauv zoo.

Cov ntsiab lus yeej:
(1) Cov ntaub txhob lo lo ntxhuav uas muaj cov kab mob, plua plav thiab tsuas yog tuaj yeem ntxuav qhuav xwb, tab sis tsis yooj yim los tsim hluav taws xob zoo li qub, nws tsis yooj yim rau nqus cov plua plav hauv huab cua, thiab tsis muaj cov ntaub txhob lo lo ntxhuav yooj yim noj cov qhov tsis zoo, yooj yim saib xyuas.
(2) Muaj ib qho thermoplasticity zoo, cov duab yooj yim dua los kho, piv nrog cov khoom siv hemp, tsis yooj yim rau wrinkle, nrog rau cov dej noo nqus ntawm linen, tib lub sijhawm, nrog rau kev xav ntawm loog, txias thaum hnav.
(3) Nrog rau kev nplij siab ntawm cov fibers ntuj, qhov no zoo dua li cov fibers dag. Tib lub sijhawm, qhov elasticity ntawm viscose fiber zoo dua, tab sis kuj yooj yim rau zas xim, thiab xim fastness siab dua.

4. Daim ntawv thov thiab kev tso cov ntaub acetic acid hauv kev tsim khaub ncaws

Tus nqi ntawm cov ntaub acetic acid kim heev, nws txiav txim siab siv cov khaub ncaws zoo, nrog rau lwm cov satin, lossis cov khoom siv TR tsis tuaj yeem hloov pauv, raws li hom nqi siv, kom pom tias nws puas haum rau hom.

(1) Tsim qauv zam --tiab

Acetic acid ntaub ua lubtiab luv luv, yog txoj kev ace, thiab peb tuaj yeem muaj ntau txoj hauv kev sib txawv los txhais lus raws li qhov sib txawv ntawm cov ntaub, nrog rau cov qauv ntaub.

Brand: Ssheena
Cov khoom xyaw: triacetate 82%, ethylene 18%)

(2) Tsim qauv zam -- ris
Los yog ib lo lus hais qub: tsim ris tsho, tsis tuaj yeem sib cais los ntawm qhov dav thiab qhov sag ntawm daim ntaub. Cov khoom siv acetic acid zoo ib yam, them sai sai rau qhov kev xav ntawm satin ntawm acetic acid, kuj yuav hook phenomenon.
