Koma pokhapokha ngati zisamatenthedwe ndi moto, nsalu zonse ziwirizi zimatha kusungunuka kapena kuonongeka mosavuta zikatenthedwa ndi kutentha kwambiri. Izi zimachitika chifukwa chopangidwa ndi pulasitiki, yomwe imasungunuka kutentha kwambiri kuposa zipangizo zina.

Kapangidwe

Maonekedwewo mwina ndi amodzi mwa malo omwe nsalu ziwirizi zimasiyana kwambiri. Chifukwa ndi nsalu yosunthika yokhala ndi ntchito zambiri, polyester imatha kukhala ndi mawonekedwe osiyanasiyana. Kawirikawiri, nsalu za polyester zimakhala zosalala komanso zofewa. Ngakhale polyester sikhala yofewa ngati thonje, imatha kumva mofanana koma imakhala yolimba pang'ono. Mukhozanso kutsuka ulusi wa polyester m'njira zosiyanasiyana kuti mupange mawonekedwe ambiri, kuphatikizapo fluffy, momwe timathera ndi mitundu yosiyanasiyana ya nsalu za ubweya.

Poyerekeza ndi polyester, polyurethane ili ndi mawonekedwe okhwima. Ikadali yosalala koma osati yofewa. M'malo mwake, ndizovuta ndipo nthawi zina zimakhala ndi mawonekedwe ofanana ndi a chikopa. Izi ndichifukwa cha zokutira zomwe zimagwiritsidwa ntchito kuphimba nsalu. Polyurethane ikagwiritsidwa ntchito kupanga spandex, ilibe mawonekedwe ngati chikopa. M'malo mwake, ndi yosalala ndipo imakhala yofewa pang'ono. Koma ponseponse, polyester ili ndi mwayi pankhani yofewa.

Kufunda

Polyester ndi polyurethane onse ndi nsalu zofunda. Polyester ndi yofunda chifukwa imapuma ndipo imalola mpweya wotentha kuti uziyenda pansalu. Ndipo ukagwiritsidwa ntchito ngati ubweya, mawonekedwe ake ndi ofunda kwambiri komanso amateteza khungu lanu.

Chifukwa nsaluyo imakutidwa, imatha kuwoneka ngati polyurethane si yotentha. Koma kwenikweni ali ndi katundu wotetezera, choncho amapereka kutentha kwakukulu kwa wovala. Mtundu wina wa polyurethane, thovu la polyurethane, umagwiritsidwanso ntchito popanga nyumba ndi nyumba.

Chinyezi-Kuwononga

Polyester ndi polyurethane onse ali ndi mphamvu zowotcha chinyezi. Polyester simalo otetezedwa ndi madzi, koma samamva madzi. Izi zikutanthauza kuti zidzasunga madzi ndi mitundu ina ya chinyontho pa zovala zanu mpaka zovalazo zitakhuta. Madzi aliwonse amene afika pansaluyo ayenera kukhala pafupi ndi pamwamba pa nsaluyo ndi kusanduka nthunzi msanga.

Nsalu ya polyurethane ili pafupi kuti zisalowe madzi. Madzi amakhala ovuta kulowa mkati mwa nsalu yomwe imakhala ndi zokutira za polyurethane. Chophimbacho chimakhala ngati chitetezo cha nsalu. Zimagwira ntchito mofanana ndi kugwiritsa ntchito zosindikizira za polyurethane pamipando yakunja. Madzi amaundana mmwamba kapena amatsetsereka kuchokera pansalu ngati anyowa. Ndipo mosiyana ndi chikopa chomwe chimatha kuwonongeka chifukwa cha madzi, nsalu ya polyurethane imakhalabe yopanda vuto.

Wotambasula

Ulusi wa poliyesitala siwotambasuka wokha. Koma ulusiwo amalukidwa pamodzi m’njira yopangitsa nsaluyo kukhala yotambasuka. Ngakhale zili choncho, si nsalu yotambasula kwambiri. Nthawi zina ulusi wotanuka monga spandex umaphatikizidwa ndi ulusi wa polyester kuti uwonjezeke.

Polyurethane imadziwika kuti elastomeric polima, zomwe zikutanthauza kuti ndi yotambasuka kwambiri.

Ulusi womwewo ndi wamphamvu kwambiri kuposa mphira ndipo "singathe" ndikutaya matalala ake pakapita nthawi. Chifukwa chake, ulusi wa polyurethane umagwiritsidwa ntchito popanga spandex.

Kusavuta Kusamalira

Polyester ndi polyurethane onse ndi osavuta kuwasamalira chifukwa cha kulimba kwawo komanso kufota komanso kusagwira makwinya. Polyester ndiyopanda madontho komanso ambiri amatha kuchotsedwa ndi madontho osasamba. Kenako, mutha kungoponya chinthucho mu makina ochapira ndikutsuka pamayendedwe abwinobwino ndi madzi ofunda kapena ozizira.

Ndi polyurethane, zotayika zambiri zimatha kuchotsedwa ndi sopo ndi madzi. Mukhozanso kutsuka mu makina ochapira monga momwe mumatsuka polyester. Chofunika kukumbukira ndi nsalu zonsezi ndikuti simukufuna kuzitsuka m'madzi otentha ndipo simukufuna kuziwumitsa pogwiritsa ntchito kutentha kwakukulu chifukwa cha kuwonongeka komwe kungachitike. Kuyanika mpweya kapena kuumitsa kutentha pang'ono ndibwino.

Mtengo

Nsalu zonsezi ndi zotsika mtengo kwambiri. Polyester ndi imodzi mwa mitundu yotsika mtengo kwambiri ya nsalu ndipo imabwera mumitundu yosiyanasiyana yamitundu. Chifukwa cha mawonekedwe ake komanso mawonekedwe ake, polyurethane imagwiritsidwa ntchito ngati njira yotsika mtengo kuposa chikopa ndipo imabwera mumitundu yosiyanasiyana.

Polyester imagwiritsidwa ntchito kwambiri pazovala, makamaka zamasewera. Itha kugwiritsidwanso ntchito ngati mathalauza, malaya abatani, ma jekete, ndi zipewa. Polyester imagwiritsidwanso ntchito popanga nsalu zina zapakhomo, kuphatikiza mabulangete, zofunda, ndi zokutira.

Polyurethane sizinthu zambiri monga polyester. Chifukwa cha kukana kwambiri kwa nsaluyo kuti isapse komanso kulimba kwake, imagwiritsidwa ntchito pazovala zambiri zamafakitale, makamaka pazitsulo zamafuta. Imakhala ndi ntchito zambiri kuposa polyester. Mutha kupezanso matewera, ma raincoats, ndi ma vests omwe amapangidwa kuchokera ku polyurethane.

Ubwino ndi kuipa kwa Polyester

Pankhani ya polyester, ubwino wake umaposa kuipa. Poyambira, polyester ndi imodzi mwazolimba kwambiri, zotsika mtengo, komanso zosavuta kusamalira nsalu zomwe zilipo. Komanso sichitha banga, kufota, ndi kusamva makwinya. Potsirizira pake, ndi chinyezi, zomwe zikutanthauza kuti zimakupangitsani kuti muziuma ndi kuuma mwamsanga ngati zinyowa.

Polyester ili ndi zovuta zingapo poyerekeza ndi polyurethane. Kale sichimapuma monga nsalu zina, koma nthawi zina zimatha kupuma pang'ono kusiyana ndi polyurethane, malingana ndi zomwe zimapanga nsalu za polyurethane. Komanso siyotambasuka ngati polyurethane ndipo imasamva madzi m'malo mopanda madzi. Pomaliza, poliyesitala sangathe kulekerera kutentha kwakukulu, kotero muyenera kusamala momwe mumatsuka ndi kuumitsa.

Ubwino ndi kuipa kwa Polyurethane

Mofanana ndi polyester, nsalu ya polyurethane ili ndi ubwino wambiri kusiyana ndi kuipa. Nthawi zina, imakhala yolimba kwambiri kuposa polyester chifukwa cha kukana kwake. Ndiwopanda madzi komanso yosavuta kuyeretsa chifukwa madontho ambiri amatha kupukuta popanda kulowa munsalu. Polyurethane ilinso ndi zinthu zoziziritsa kukhosi komanso zimakhala ndi kutsika kwambiri.

Chimodzi mwazinthu zoyipa za polyurethane ndikuti nthawi zambiri sizofewa ngati poliyesitala. Ili ndi mawonekedwe okhwima komanso okhwima kwambiri ndipo sangathe kupukuta kuti apange mitundu yosiyanasiyana ya nsalu. Ndiwosasunthika ngati poliyesitala ndipo imakhala ndi ntchito zambiri kuposa momwe imagwiritsidwira ntchito ndi mafashoni. Pomaliza, monga poliyesitala imatha kuonongeka ngati ikhudzidwa ndi kutentha kwambiri.

Chabwino n'chiti?

Tsopano popeza takambirana za polyester ndi polyurethane, ndi iti yomwe ili yabwino? Polyester ndi yabwino kuvala tsiku ndi tsiku, pamene polyurethane ili ndi ntchito yeniyeni yomwe ili yabwino. Chifukwa chake, chomwe chili chabwinoko chimangotengera mtundu wazinthu zomwe mukuyang'ana. Nthawi zambiri, simudzasowa kusankha pakati pa ziwirizi chifukwa aliyense ali ndi zolinga zosiyana.
