Nsalu ya acetate, yomwe imadziwikanso kuti nsalu ya acetate, yomwe imadziwikanso kuti Yasha, ndi katchulidwe ka Chitchaina ka ACETATE ka Chingerezi. Acetate ndi ulusi wopangidwa ndi anthu womwe umapezeka popangidwa ndi acetic acid ndi cellulose ngati zinthu zopangira. Acetate, yomwe ili m'gulu la ulusi wopangidwa ndi anthu, imakonda kutsanzira ulusi wa silika. Imapangidwa ndi ukadaulo wapamwamba wa nsalu, wokhala ndi mitundu yowala komanso mawonekedwe owala. Kukhudza kwake ndi kosalala komanso komasuka, ndipo kunyezimira ndi magwiridwe antchito ake ndi ofanana ndi a silika wa mulberry.
Poyerekeza ndi nsalu zachilengedwe monga thonje ndi nsalu ya nsalu, nsalu ya acetate imayamwa bwino chinyezi, imalowa bwino mpweya komanso imalimba, ilibe magetsi osasunthika komanso tsitsi lolimba, ndipo ndi yabwino kwambiri pakhungu. Ndi yoyenera kwambiri popanga madiresi abwino, masiketi a silika, ndi zina zotero. Nthawi yomweyo, nsalu ya acetate ingagwiritsidwenso ntchito m'malo mwa silika wachilengedwe kuti ipange zovala zapamwamba zapamwamba, monga ma trench coats, ma coat a chikopa, madiresi, ma cheongsams, madiresi aukwati, ma suit a Tang, masiketi achisanu ndi zina zambiri! Chifukwa chake aliyense amaona kuti ndi m'malo mwa silika. Zizindikiro zake zitha kuwoneka m'mawonekedwe a masiketi kapena ma coat.
Ulusi wa acetate ndi chinthu chachilengedwe chochokera ku cellulose ya pulp yamatabwa, yomwe ndi gawo lomwelo la molekyulu ya mankhwala monga ulusi wa thonje, ndi acetic anhydride ngati zinthu zopangira. Itha kugwiritsidwa ntchito popota ndi kuluka pambuyo pokonza mankhwala angapo. Ulusi wa acetate filament, womwe umatenga cellulose ngati chigoba chachikulu, uli ndi mawonekedwe oyambira a ulusi wa cellulose; koma magwiridwe ake ndi osiyana ndi ulusi wa cellulose wobwezeretsedwa (silika wa viscose cupro), ndipo uli ndi mawonekedwe ena a ulusi wopangidwa:
1. Kutentha kwabwino: Ulusi wa acetate umafewa pa 200℃ ~ 230℃ ndikusungunuka pa 260℃. Izi zimapangitsa kuti ulusi wa acetate ukhale ndi kutentha kwabwino kofanana ndi ulusi wopangidwa. Pambuyo pa kusintha kwa pulasitiki, mawonekedwe ake sadzachira, ndipo kusinthako kudzakhala kosatha. Nsalu ya acetate imakhala ndi mawonekedwe abwino, imatha kukongoletsa kupindika kwa thupi la munthu, ndipo ndi yokongola komanso yokongola.
2. Kupaka utoto kwabwino kwambiri: Ulusi wa acetate nthawi zambiri umapakidwa utoto ndi utoto wosakanikirana, ndipo umakhala ndi utoto wabwino komanso mitundu yowala, ndipo utoto wake ndi wabwino kuposa ulusi wina wa cellulose. Nsalu ya acetate imakhala ndi kutentha kwabwino. Ulusi wa acetate umafewa pa 200 ° C ~ 230 ° C ndikusungunuka pa 260 ° C. Mofanana ndi ulusi wopangidwa, mawonekedwe ake sadzachira pambuyo pa kusintha kwa pulasitiki, ndipo amakhala ndi kusintha kosatha.
3. Maonekedwe ngati silika wa mulberry: Maonekedwe a ulusi wa acetate ndi ofanana ndi a silika wa mulberry, ndipo mawonekedwe ake ofewa komanso osalala m'manja ndi ofanana ndi a silika wa mulberry. Mphamvu yake yeniyeni ndi yofanana ndi ya silika wa mulberry. Nsalu yolukidwa ndi silika wa acetate ndi yosavuta kutsuka ndi kuuma, ndipo ilibe bowa kapena njenjete, ndipo kulimba kwake kuli bwino kuposa ulusi wa viscose.
4. Kagwiridwe ka ntchito ka silika wa mulberry: poyerekeza ndi mphamvu zakuthupi ndi zamakaniko za ulusi wa viscose ndi silika wa mulberry, mphamvu ya ulusi wa acetate ndi yotsika, kutalika kwake pakagwa n’kokulirapo, ndipo chiŵerengero cha mphamvu yonyowa ndi mphamvu youma n’chochepa, koma chapamwamba kuposa cha silika wa viscose. , modulus yoyamba ndi yaying’ono, kubwezeretsedwa kwa chinyezi n’kochepa kuposa cha ulusi wa viscose ndi silika wa mulberry, koma chapamwamba kuposa cha ulusi wopangidwa, chiŵerengero cha mphamvu yonyowa ndi mphamvu youma, mphamvu yolumikizirana ndi mphamvu yolumikizirana, kuchuluka kwa kuchira kwa elasticity, ndi zina zotero. Chifukwa chake, mphamvu za ulusi wa acetate ndizofanana kwambiri ndi za silika wa mulberry pakati pa ulusi wa mankhwala.
5. Nsalu ya acetate siili ndi magetsi; sikophweka kuyamwa fumbi mumlengalenga; kutsuka mouma, kutsuka m'madzi ndi kusamba m'manja ndi makina pansi pa 40 ℃ kungagwiritsidwe ntchito, zomwe zimathetsa kufooka kwa nsalu za silika ndi ubweya zomwe nthawi zambiri zimakhala ndi mabakiteriya; fumbi ndipo zimatha kutsukidwa mouma kokha, ndipo palibe nsalu za ubweya zomwe zimadyedwa mosavuta ndi tizilombo. Choyipa chake ndi chakuti ndizosavuta kusamalira ndi kusonkhanitsa, ndipo nsalu ya acetate imakhala yolimba komanso yosalala ngati nsalu za ubweya.
Zina: Nsalu ya acetate ili ndi ndipo imaposa nsalu za thonje ndi nsalu za nsalu zokhala ndi zinthu zosiyanasiyana, monga kuyamwa chinyezi ndi kupuma bwino, kusakhala ndi thukuta, kutsuka mosavuta komanso kuuma, kusakhala ndi bowa kapena njenjete, kumasuka pakhungu, kusakhala ndi chilengedwe, ndi zina zotero.
