Makhalidwe a ulusi wa polyester wamphamvu kwambiri ndi wodabwitsa, womwe ungafotokozedwe mwachidule motere:
1. Ulusi wa polyester wamphamvu kwambiri uli ndi mphamvu zambiri.Mphamvu zazifupi za ulusi ndi 2.6 ~ 5.7 cn/dtex, ndipo mphamvu ya fiber yamphamvu kwambiri ndi 5.6 ~ 8.0 cn/dtex.Chifukwa cha kuchepa kwa hygroscopicity, mphamvu yake yonyowa imakhala yofanana ndi mphamvu yake youma.Mphamvu yamphamvu ndi 4 kuwirikiza kuposa nayiloni komanso nthawi 20 kuposa ulusi wa viscose.
2. Ulusi wa poliyesitala wamphamvu kwambiri uli ndi kusungunuka kwabwino.Kutanuka kuli pafupi ndi ubweya wa ubweya, ndipo kumatha kuchira kwathunthu ngati atatambasulidwa ndi 5% ~ 6%.Kukana kwa crease ndikwabwino kuposa ulusi wina, ndiye kuti, nsaluyo simakwinya ndipo imakhala yokhazikika bwino.Etastic modulus ndi 22 ~ 141 cn/dtex, yomwe ndi 2 ~ 3 nthawi yayitali kuposa ya nayiloni.Nsalu ya poliyesitala imakhala ndi mphamvu zambiri komanso mphamvu yobwezeretsa zotanuka, chifukwa chake, imakhala yolimba komanso yolimba, yosagwira makwinya komanso yosasita.
3. Polyester yamphamvu kwambiri ya polyester filament Kutentha kosagwira polyester kumapangidwa ndi kusungunula kupota, ndipo ulusi wopangidwa ukhoza kutenthedwa ndi kusungunuka kachiwiri, womwe ndi wa thermoplastic fiber.Malo osungunuka a poliyesitala ndi okwera kwambiri, koma kutentha kwapadera ndi matenthedwe amatenthedwe onse ndi ang'onoang'ono, kotero kukana kutentha ndi kutentha kwa polyester fiber ndipamwamba.Ndiwo fiber yabwino kwambiri yopangira.
4. Ulusi wa poliyesitala wamphamvu kwambiri uli ndi thermoplasticity yabwino komanso kusamasungunuka bwino.Chifukwa cha mawonekedwe ake osalala komanso makonzedwe olimba a mamolekyu amkati, poliyesitala ndi nsalu yabwino kwambiri yosamva kutentha munsalu zopangira ulusi, zomwe zimakhala ndi thermoplasticity ndipo zimatha kugwiritsidwa ntchito popanga masiketi otakata, ndipo zokopazo zimatha kwa nthawi yayitali.Panthawi imodzimodziyo, kukana kusungunuka kwa nsalu ya polyester kumakhala kovuta, ndipo n'kosavuta kupanga mabowo mukakumana ndi mwaye, zopsereza, ndi zina zotero.
5. Ulusi wa poliyesitala wamphamvu kwambiri uli ndi kukana kwabwino kovala.Kukaniza abrasion ndi yachiwiri kwa nayiloni yokhala ndi kukana bwino kwambiri kwa abrasion, yomwe ili yabwino kuposa ulusi wina wachilengedwe ndi ulusi wopangidwa.
6. Ulusi wa polyester wamphamvu kwambiri uli ndi kukana kwabwino kwa kuwala.Kuthamanga kwa kuwala ndi kwachiwiri kwa acrylic.Kuwala kowala kwa nsalu ya polyester ndikwabwino kuposa acrylic fiber, ndipo kuwala kwake kumakhala bwino kuposa nsalu yachilengedwe.Makamaka kumbuyo kwa galasi, kuwala kwachangu kumakhala kwabwino kwambiri, pafupifupi kofanana ndi acrylic fiber.
7. Ulusi wa poliyesitala wolimba kwambiri umalimbana ndi dzimbiri.Kugonjetsedwa ndi blekning agents, oxidants, hydrocarbons, ketoni, mafuta a petroleum ndi ma inorganic acid.Imalimbana ndi kusungunuka kwa alkali komanso osawopa mildew, koma imatha kuwola ndi alkali yotentha.Ilinso ndi asidi amphamvu ndi kukana kwa alkali komanso kukana kwa ultraviolet.
8. Kusaoneka bwino kwa utoto, koma kufulumira kwamtundu wabwino, kosavuta kuzimiririka.Chifukwa palibe gulu lapadera lopaka utoto pamtundu wa molekyulu wa polyester, ndipo polarity ndi yaying'ono, ndizovuta kuyika utoto, ndipo utoto umakhala wosauka, kotero kuti mamolekyu a utoto sali osavuta kulowa mu fiber.
9. Nsalu ya polyester yamphamvu kwambiri imakhala ndi hygroscopicity yosauka, kumverera kwa sultry ikavala, ndipo panthawi imodzimodziyo, imakhala ndi magetsi osasunthika komanso kuipitsidwa kwa fumbi, zomwe zimakhudza kukongola kwake ndi chitonthozo.Komabe, ndizosavuta kuumitsa mukatha kuchapa, ndipo mphamvu yake yonyowa simatsika ndipo simapunduka, motero imakhala yabwino yochapitsidwa komanso kuvala.
Chidule:
Nsalu yopangidwa ndi silika yamphamvu kwambiri ya polyester ili ndi ubwino wokhala ndi mphamvu zabwino, zosalala ndi zowuma, kuchapa mosavuta ndi kuumitsa mwamsanga, koma zimakhala ndi zovuta zina monga dzanja lolimba, kukhudza kosauka, kuwala kofewa, kuperewera kwa mpweya komanso kuyamwa kwa chinyezi.Poyerekeza ndi nsalu zenizeni za silika, kusiyana kwake kumakhala kokulirapo, kotero ndikofunikira kutsanzira silika pamapangidwe a silika poyamba kuti athetse kuipa kwa kuvala koyipa.
