1.Polyesterfiber
Polyester CHIKWANGWANI ndi poliyesitala, wa poliyesitala kusinthidwa, wa zosiyanasiyana ankachitira (kusinthidwa ndi abwenzi kukumbukira) izo bwino poliyesitala madzi okhutira ndi otsika, permeability osauka, utoto osauka, pilling zosavuta, zosavuta banga ndi zofooka zina. Zimatengera woyengedwa terephthalic acid (PTA) kapena dimethyl terephthalate (DMT) ndi ethylene glycol (EG) monga zopangira kudzera esterification kapena transesterification ndi condensation anachita kukonzekera kupanga polima - polyethylene terephthalate (PET), spun ndi pambuyo mankhwala anapanga. wa fiber.
Ubwino: kuwala kowala, ndi kung'anima kwenikweni, kumva bwino, lathyathyathya, elasticity wabwino; Anti-khwinya ironing, kukana bwino kuwala; Gwirani silika mwamphamvu ndi dzanja ndikumasula popanda kukwapula koonekera.
Zoipa: luster si yofewa mokwanira, permeability osauka, zovuta utoto, osauka kusungunuka kukana, zosavuta kupanga mabowo pamaso pa mwaye, Mars ndi zina zotero.
Kupezeka kwa polyester
Polyester, yopangidwa mu 1942 ndi JR Whitfield ndi JT Dixon, idalimbikitsidwa ndi kafukufuku wa WH Carothers, wasayansi waku America yemwe adapeza nayiloni! Ikagwiritsidwa ntchito ngati ulusi, imatchedwanso poliyesitala, ndipo ngati imagwiritsidwa ntchito, mwachitsanzo, mabotolo akumwa apulasitiki, amatchedwa PET.
Njira: Kupanga ulusi wa polyester nthawi zambiri kumaphatikizapo njira zotsatirazi
(1) Polymerization: asidi terephthalic ndi ethylene glycol (nthawi zambiri ethylene glycol) ndi polymerized kupanga poliyesitala polima;
(2) Kupota: posungunula polima ndikudutsa mu mbale yozungulira pore kuti apange ulusi wopitirira;
(3) Kuchiritsa ndi kutambasula: ulusi umazirala ndikuchiritsidwa ndikutambasulidwa pa machira kuti ukhale wolimba komanso wolimba;
(4) Kupanga ndi pambuyo mankhwala: ulusi akhoza kupangidwa mwa njira zosiyanasiyana monga nsalu, kuluka, kusoka, ndi pambuyo mankhwala, monga utoto, kusindikiza ndi kumaliza.
Ulusi wopangidwa ndi polyester ndi wosavuta kwambiri pamizere itatu yopangira, ndipo mtengo wake ndi wotsika mtengo. Ndi mtundu wa nsalu zopangidwa ndi fiber zomwe zimagwiritsidwa ntchito pamoyo watsiku ndi tsiku. Ubwino wake waukulu ndikuti uli ndi kukana bwino kwa makwinya ndi kusungidwa kwa mawonekedwe, kotero ndi yoyenera kwa zinthu zakunja monga zovala zakunja, matumba amitundu yonse ndi mahema.
Ubwino: mphamvu yayikulu, kukhazikika kolimba pafupi ndi ubweya; Kukana kutentha, kukana kuwala, kukana kuvala bwino komanso kukana kwa mankhwala;
Kuipa kwake: kusadetsedwa bwino, kusasungunuka bwino, kusayamwa bwino kwa chinyezi komanso kupilira kosavuta, kosavuta kuyipitsa.
2.Thonje
Amatanthauza nsalu yopangidwa kuchokera ku thonje ngati zopangira. Kawirikawiri, nsalu za thonje zimakhala ndi mayamwidwe abwino a chinyezi komanso kukana kutentha ndipo zimakhala zomasuka kuvala. Ena mwa makampani opanga zovala omwe ali ndi zofunika kwambiri zoyamwa chinyezi amatha kusankha nsalu za thonje zoyera kuti azikonza. Mwachitsanzo, yunifolomu ya sukulu m'chilimwe.
Ubwino: thonje CHIKWANGWANI chinyezi mayamwidwe bwino, elasticity ndi ndi mkulu, kutentha ndi kukana zamchere, thanzi;
Zoipa: zosavuta kukwinya, zosavuta kufota, zosavuta mapindikidwe, zosavuta kumamatira tsitsi amaopa kwambiri asidi, pamene anaikira sulfuric acid zothimbirira thonje, thonje kuwotchedwa mu mabowo.
3.Nayiloni
nayiloni ndi dzina lachi China la nayiloni yopanga ulusi, dzina lomasulira limatchedwanso "nayiloni", "nayiloni", dzina lasayansi ndi polyamide fiber, ndiko kuti, polyamide fiber. Chifukwa fakitale ya Jinzhou Chemical fiber ndi fakitale yoyamba yopanga polyamide fiber mdziko lathu, imatchedwa "nayiloni". Ndiwo mtundu wakale kwambiri padziko lonse lapansi wopangira ulusi, chifukwa cha magwiridwe ake abwino, zopangira zopangira, zakhala zikugwiritsidwa ntchito kwambiri.
Ubwino: wamphamvu, kukana kuvala bwino, kusanja koyamba pakati pa ulusi wonse; Kutanuka komanso kulimba kwa nsalu ya nayiloni ndizabwino kwambiri.
Zoipa: Ndizosavuta kupunduka pansi pa mphamvu yaing'ono yakunja, kotero kuti nsalu yake imakhala yosavuta kukwinya povala; Kupanda mpweya wabwino, kosavuta kupanga magetsi osasunthika.
4.Spandex
Spandex ndi mtundu wa ulusi wa polyurethane, chifukwa cha kusungunuka kwake bwino, umadziwikanso kuti zotanuka, zomwe zimagwiritsidwa ntchito kwambiri mu nsalu za zovala ndipo zimakhala ndi makhalidwe apamwamba kwambiri. Amagwiritsidwa ntchito kwambiri popanga zovala zolimba, zovala zamasewera, jockstrap ndi sole, etc. Zosiyanasiyana zake malinga ndi zosowa za ntchito, zitha kugawidwa mu nsalu zotanuka zotanuka, nsalu zotanuka zotanuka, zotanuka komanso zopindika komanso nsalu ziwiri zotanuka.
Ubwino: kukulitsa kwakukulu, kusunga mawonekedwe abwino, komanso opanda makwinya; Kusungunuka kwabwino kwambiri, kukana kuwala, kukana kwa asidi, kukana kwa alkali, kukana kuvala; Ili ndi katundu wabwino wodaya ndipo siyenera kuzimiririka.
Zoipa: mphamvu yoyipa kwambiri, kuyamwa bwino kwa chinyezi; Spandex nthawi zambiri sichigwiritsidwa ntchito yokha, koma imaphatikizidwa ndi nsalu zina; Kukana kutentha kosakwanira.
