Kodi Nsalu Yamtundu Wanji Ndi Fiber ya Polyester Mu "Malangizo Osinthitsa Chikwama"?

Polyester fiber, yomwe imadziwika kuti "polyester".Ndizitsulo zopangidwa ndi polyester yozungulira yomwe imapezedwa ndi polycondensation ya organic dibasic acid ndi dihydric alcohol.Ndi gulu la polima ndipo ndi mitundu yayikulu kwambiri ya ulusi wopangira pano.Nsalu za poliyesitala zimagwiritsidwa ntchito kwambiri popanga katundu, ndipo nsalu za polyester zimagwiritsidwa ntchito pazinthu zambiri zamatumba.Chifukwa chake, ngati muwona "fiber ya polyester" yolembedwa pazofotokozera za chikwama cham'mbuyo, ndiye kuti chikwamacho chimapangidwa ndi nsalu ya polyester.

Nsalu ya polyester ndi imodzi mwansalu zachizolowezi zopangira zikwama.Ili ndi kukana bwino kwa makwinya, kusungirako mawonekedwe, mphamvu yayikulu komanso mphamvu yobwezeretsa zotanuka, kukana makwinya, kulibe kusita, tsitsi lopanda ndodo ndi zabwino zina.

1. Kutanuka kwa nsalu ya polyester ndikwabwino
Nsalu ya polyester imakhala ndi mphamvu zambiri komanso mphamvu yobwezeretsa, ndipo imakhala ndi kukana makwinya komanso kusunga mawonekedwe.Amagwiritsidwa ntchito popanga zikwama.Chikwama chomalizidwa ndi champhamvu komanso chosavala.Nsaluyo simapunduka mosavuta chifukwa cha mphamvu yakunja, imalimbana ndi makwinya, ndipo kwenikweni safuna kusita., mawonekedwe a thupi la phukusi adzakhala ochepa, amitundu itatu komanso okongola.Pogwiritsidwa ntchito bwino, zikwama zopangidwa ndi nsalu za poliyesitala zimakhala zolimba komanso sizimapunduka mosavuta.

2. Kukana kuwala kwabwino
Kuwala kumakhala kwachiwiri kwa acrylic (ubweya wochita kupanga).Kuwala kowala kwa nsalu ya polyester ndikwabwino kuposa acrylic fiber, ndipo kuwala kwake kumakhala bwino kuposa nsalu yachilengedwe.Makamaka kuwala kowala kumbuyo kwa galasi ndikwabwino kwambiri, pafupifupi kofanana ndi acrylic.Zogulitsa zam'chikwama zopangidwa ndi nsalu za poliyesitala sizimakonda kugwa, kuphulika ndi kusweka zikagwiritsidwa ntchito kunja.

3. Kusaoneka bwino kwa utoto
Ngakhale nsalu ya polyester ili ndi utoto wosawoneka bwino, imakhala ndi mitundu yabwino yothamanga.Ukadayidwa bwino, sudzazimiririka mosavuta, ndipo sudzatha mosavuta pochapira.Zimapangidwa kukhala chinthu cha chikwama, ndipo nsaluyo siili yophweka kuti iwonongeke pambuyo pa kugwiritsidwa ntchito kwa nthawi yaitali, ndipo zotsatira zosungira mtundu zimakhala zabwino kwambiri.

4. Kusakwanira kwa hygroscopicity
The hygroscopicity wa poliyesitala ndi chofooka kuposa nayiloni, kotero mpweya permeability si zabwino ngati nayiloni, koma ndendende chifukwa cha osauka hygroscopicity wa nsalu poliyesitala kuti nsalu poliyesitala n'zosavuta kuyanika pambuyo kutsuka, ndi mphamvu nsalu. sichimachepa, kotero sikophweka kupunduka.Zinthu zopangidwa ndi chikwama zimagwiritsa ntchito njira yotsuka yolondola, ndipo nthawi zambiri sizimawonongeka chifukwa chachapa.

5. Thermoplasticity yabwino komanso kukana kusungunuka kosasunthika
Chifukwa chosalala pamwamba pa poliyesitala komanso kuyandikira kwa mamolekyu amkati, poliyesitala ndiye nsalu yokhala ndi kukana kutentha kwambiri pakati pa nsalu zopangidwa ndi ulusi ndipo imakhala ndi thermoplastic.Choncho, zikwama za nsalu za polyester ziyenera kuyesetsa kupewa kukhudzana ndi ndudu za ndudu, zopsereza, ndi zina zotero.
