Nubwo umwenda wa polyester hamwe nigitambara cya polyester ni imyenda ibiri itandukanye, mubyukuri irasa, kandi ni imyenda ya polyester hamwe nipamba. Umwenda "Polyester-ipamba" bivuze ko ibigize polyester birenga 60%, naho ipamba iri munsi ya 40%, nanone yitwa TC; "ipamba polyester" ni ikinyuranyo, bivuze ko ibigize ipamba birenga 60%, naho polyester ni 40%. Nyuma, byitwa kandi CVC Imyenda.
Polyester-ipamba ivanze ni ubwoko butandukanye bwateye imbere mugihugu cyanjye muntangiriro ya 1960. Bitewe nibyiza biranga polyester-ipamba nko gukama vuba no koroha, irakundwa cyane nabaguzi.
1.Ibyiza byaumwenda wa polyester
Kuvanga polyester-ipamba ntibigaragaza gusa uburyo bwa polyester ahubwo binagira ibyiza byimyenda. Ifite elastique nziza kandi yambara irwanya mubihe byumye kandi bitose, ingano ihamye, kugabanuka gato, kugororotse, ntibyoroshye kubyimba, byoroshye gukaraba, gukama vuba nibindi biranga.
2.Ibibi by'imyenda ya polyester
Fibre ya polyester muri polyester-ipamba ni fibre hydrophobique, ifitanye isano ikomeye n’amavuta y’amavuta, biroroshye gukuramo amavuta y’amavuta, byoroshye kubyara amashanyarazi ahamye kandi ikurura umukungugu, biragoye koza, kandi ntibishobora gukonjeshwa ubushyuhe bwinshi cyangwa ngo ushiremo amazi abira. Uruvange rwa polyester-ipamba ntabwo rworoshye nkipamba, kandi ntirwinjira nkipamba.
3.Ibyiza by'imyenda ya CVC
urumuri ruba ruto cyane kuruta urw'ipamba yera, hejuru yigitambara kiroroshye, gisukuye kandi kitarangwamo imishumi cyangwa ibinyamakuru. Yumva yoroshye kandi yoroheje, kandi irwanya iminkanyari kuruta imyenda y'ipamba.
None, niyihe mwenda ibiri "ipamba rya polyester" na "ipamba polyester" iruta iyindi? Ibi biterwa nibyifuzo byabakiriya nibyifuzo byabo. Nukuvuga ko, niba ushaka umwenda wishati kugira byinshi biranga polyester, hitamo "ipamba ya polyester", kandi niba ushaka ibiranga ipamba, hitamo "ipamba polyester".
Ipamba rya polyester nuruvange rwa polyester nipamba, ntabwo byoroshye nkipamba. Kwambara kandi ntabwo ari byiza nko kwinjiza ibyuya. Polyester nubwoko bunini hamwe nibisohoka cyane muri fibre synthique. Polyester ifite amazina menshi yubucuruzi, kandi "polyester" nizina ryubucuruzi bwigihugu cyacu. Izina ryimiti ni polyethylene terephthalate, ubusanzwe ikorwa na polymer yimiti, bityo izina ryubumenyi rikunze kugira "poly".
Polyester nayo yitwa polyester. Imiterere n'imikorere: Imiterere yimiterere igenwa nu mwobo wa spinneret, kandi kwambukiranya igice cya polyester isanzwe ni umuzenguruko udafite umwobo. Fibre ifite ishusho irashobora kubyara muguhindura imiterere yibice bya fibre. Itezimbere urumuri hamwe. Fibre macromolecular kristalline hamwe nicyerekezo cyo hejuru cyerekezo, bityo imbaraga za fibre ni nyinshi (inshuro 20 ziva muri fibre viscose), kandi kurwanya abrasion nibyiza. Elastique nziza, ntabwo yoroshye kubyimba, kugumana imiterere myiza, kurwanya urumuri rwiza no kurwanya ubushyuhe, gukama vuba no kudatera ibyuma nyuma yo gukaraba, gukaraba neza no kwambara.
Polyester ni umwenda wa fibre fibre idashobora kubira ibyuya byoroshye. Irumva gutera icyuma gukoraho, biroroshye kubyara amashanyarazi ahamye, kandi isa neza iyo ihengamye.
Polyester-ipamba ivanze ni ubwoko butandukanye bwateye imbere mugihugu cyanjye muntangiriro ya 1960. Fibre ifite ibiranga crisp, yoroshye, yumisha vuba, kandi iramba, kandi ikundwa cyane nabaguzi. Kugeza ubu, imyenda ivanze yateye imbere kuva ku kigereranyo cyambere cya 65% polyester kugeza kuri 35% ipamba kugeza kumyenda ivanze hamwe nibipimo bitandukanye bya 65:35, 55:45, 50:50, 20:80, nibindi. Intego nukumenyera nzego zitandukanye. abaguzi bakeneye.
