Polyester - thonjensalu zosakanizandi mitundu yomwe idapangidwa ku China koyambirira kwa zaka za m'ma 1960.Fiber iyi ndi yolimba, yosalala, yowuma mofulumira komanso yosavala.Ndiwotchuka pakati pa ogula ambiri.Nsalu ya thonje ya poliyesitala imatanthawuza ulusi wophatikizika wa ulusi wa poliyesitala ndi ulusi wa thonje, zomwe sizimangowonetsa mawonekedwe a poliyesitala komanso zimakhala ndi zabwino za nsalu za thonje.
Zochita za polyester:
Monga chinthu chatsopano chosiyanitsa fiber,polyester fiberali ndi mbali ya mphamvu mkulu, modulus lalikulu, elongation yaing'ono ndi wabwino dimensional bata, etc. Iwo ali zofewa kapangidwe, wabwino cohesive mphamvu, wodekha luster ndi zina pachimake kutentha kwenikweni.Mayamwidwe a chinyezi a polyester ndi osauka.Ndipo pansi pamikhalidwe yamlengalenga, chinyezi chimayambanso pafupifupi 0.4%.Chifukwa chake kumakhala kotentha komanso kodzaza kuvala nsalu yoyera ya polyester.Koma nsalu ya polyester ndi yosavuta kutsuka ndi kuumitsa mwamsanga, yomwe ili ndi dzina labwino la "kutsuka ndi kuvala".Polyester ili ndi modulus yapamwamba, yomwe imakhala yachiwiri kwa hemp fiber, ndipo imakhala ndi mphamvu yabwino.Choncho, nsalu ya polyester ndi yolimba komanso yotsutsana ndi makwinya.Ndi yokhazikika kukula kwake ndipo imakhala ndi mawonekedwe abwino.Polyester ili ndi kukana bwino kwa abrasive, yomwe ili pafupi ndi nayiloni.Koma ndi udindo wa pilling ndipo mipira si yosavuta kugwa.
Mawonekedwe a thonje:
Gawo la mtanda la ulusi wa thonje ndi chiuno chozungulira mozungulira ndi midplane mkati.Kumapeto kotenga nthawi kumatsekedwa ma cell a tubular, okulirapo pakati komanso ocheperako mbali zonse ziwiri.Natural crimp ndi chikhalidwe chapadera cha morphological cha thonje.Ulusi wa thonje umalimbana ndi alkali koma sulimbana ndi asidi.Imakhala ndi mayamwidwe amphamvu.Pansi pa chikhalidwe chokhazikika, chinyontho chobwezeretsanso ulusi wa thonje ndi 7 ~ 8%.Pambuyo pokonzedwa kwa maola 8 pa kutentha kwa 100 ℃, mphamvu zake sizimakhudzidwa.Pa 150 ℃, ulusi wa thonje udzawola, ndipo pa 320 ℃, udzayaka.Ulusi wa thonje uli ndi kukana kwenikweni, komwe sikophweka kupanga magetsi osasunthika pokonza ndikugwiritsa ntchito.
Ubwino wa zosakaniza za polyester-thonje:
Nsalu zosakanikirana za polyester-thonje sizimangotsindika kalembedwe ka polyester, komanso zimakhala ndi ubwino wa thonje.Pamalo owuma ndi onyowa, imakhala ndi elasticity yabwino, kukana bwino kwa abrasive, kukula kokhazikika ndi kuchepa pang'ono.Ndilolimba, silosavuta kukumba, yosavuta kutsuka komanso kuyanika mwachangu.Ili ndi kuwala kowala.Kumverera kwa dzanja ndi kosalala, kolimba komanso zotanuka.Pambuyo pakupukuta pamanja, crease sikuwonekera ndipo imachira mwachangu.Koma ilinso ndi zofooka zomwezo ngati ulusi wamankhwala womwe gawo la friction ndi losavuta kupukuta ndikupukuta.Nsalu zosakanikirana ndi thonje la polyester zimakhala ndi manja okhuthala komanso ofewa.Ndi bwino kuvala.Ikhoza kusunga mawonekedwe ake mutatsuka mobwerezabwereza popanda kufota kapena kuchepa.
Polyester-thonje ndi thonje-polyester:
Polyester-thonje ndi thonje-polyester ndi mitundu iwiri ya nsalu zosiyana.
Nsalu ya 1.Polyester-thonje (TC) imatanthauzidwa ngati polyester yoposa 50% ndi thonje yosachepera 50%.
Ubwino wake: Kuwala kumawala kuposa nsalu ya thonje.Chogwirira ndi chosalala, chowuma komanso cholimba.Ndi movutitsa movutikira.Ndipo poliyesitala ikachuluka, m’pamenenso nsaluyo imakwinya.
Zoipa: Katundu wokonda khungu ndi woipa kuposa nsalu ya thonje yoyera.Ndikosavuta kuvala kuposa nsalu yoyera ya thonje.
2. Cotton-polyester (Mtengo CVC) Nsalu ndizosiyana, zomwe zimatanthauzidwa kuti ndizoposa 50% za thonje ndi poliyesitala zosakwana 50%.
Ubwino wake: Kuwalako kumawala pang'ono kuposa nsalu ya thonje.Nsaluyo imakhala yosalala komanso yoyera popanda zinyalala kapena zonyansa.Chogwiriracho ndi chosalala komanso cholimba.Imaletsa makwinya kuposa nsalu yoyera ya thonje.
Zoipa: Katundu wokonda khungu ndi woipa kuposa nsalu ya thonje yoyera.Ndikosavuta kuvala kuposa nsalu yoyera ya thonje.
