O ie alava masani mama o le cotton, hemp, siliki, fulufulu mamoe, asbestos, ma isi. E ui lava o le alava masani autu, ae e le o iai ni faʻafitauli faʻaletonu, e pei o le le mautonu o vailaʻau, faʻalagolago i le maualalo o le gaosiga o mea faʻanatura, o filo faʻanatura e faigofie ile pala. , mogamoga, mataʻu pe a uma ona faʻaoga, e le faigofie ona seti, faigofie ona maua maanuminumi, ma isi.

In consideration of more mass production, chemical fibers are put on the market in one experiment and improvement, low cost and high yield, and can be modified, easy to process and have a strong tensile properties. Such as polyester fiber, which is commonly known as polyester fabric, according to polyester has excellent shaping properties, vulu polyester and fabric by shaping or straight, or fluffy pleats, in use, even after many washes, can also maintain the original form.
Ma o mea tau vailaʻau o le polyester, polyester mole e aofia ai pupuu aliphatic filifili hydrocarbon, vaega ester, mama benzene, faʻaiʻuga o le ava hydroxyl vaega, aveese le vaega lua o le ava hydroxyl vaega, e leai se isi polar genes, o le mea lea na talanoaina ai le alava polyester. pei hydrophilic leaga.

O le mole mole polyester e aofia ai le 46% o le vaega o le ester, ma o le vaega ester e mafai ona faʻafefeteina ma faʻafefeteina i luga aʻe o le 200 ℃, ma faʻafesoʻotaʻi malosi alkali o le a saponified ma o le a faʻaitiitia le tikeri o le polymerization, ma o le vailaʻau masani masani i lalo ole 100 ℃ e leai se aoga. luga ole ie polyester.
O le ie polyester e mafai ona tetee atu i le malamalama malosi, o lea e talafeagai mo ie pupuni. Pe a faatusatusa i filo masani, o ie polyester e sili atu ona tetee i le susulu o le la. Pe a fa'amago lavalava, e to'atele tagata o le a matauina le fa'ailoga "No Exposure to Sunlight" ona o le tele o ie e ono iai ni a'afiaga pe a fa'aalia i le susulu o le la, ae i le loloto, e to'atele tagata e lagona e leai se agaga o lavalava pe a le fa'aalia i le susulu o le la (tale). , o ie polyester e mafai ona puipuia ma le saogalemu i le susulu o le la ma mea oona (haha).
O le polyester foi e matua'i fa'alelei, e tusa lava pe a uma ona solo solo, o le a vave ona toe fo'i i lona fa'ata'ita'iga, ma o le a le tu'ua ai ni fa'ailoga le manaia.
O lo'o i ai fo'i se fa'afitauli saogalemu, o ie polyester e matua'i fa'afefeteina le vevela ma o le tekonolosi o le fa'aogaina o le ausa e mafai ona uu lelei.

E lelei tele fo'i le tete'e o vaila'au o le ie polyester, fa'amama vaila'au e fufulu ai sapalai, pei o le pisia se vasega ma o le a le afaina ai le mea o le ie. Polyester lavalava e le tatau ona popole tele e uiga i limu, manatua e tuu le sefulu lua mothballs i totonu o le kapeneta ina ia mafai ona malolo mautinoa o lavalava e tuu i totonu o le kapeneta, ae popole foi e uiga i lanu samasama ma lanu umi? E tusa lava pe e te tuʻuina N mothballs, o loʻo popole pea e uiga i le fiafia o lavalava i totonu o le kapeneta, ae atonu e mafai e le ie polyester ona faʻafefeina nei ituaiga o faʻafitauli.
