Ko te polyester tētahi o ngā muka hangai tino nui, ā, koia te ingoa hokohoko o te muka polyester i Haina. Ko te waikawa terephthalic (PTA) te waikawa terephthalic dimethyl ester (DMT) me te ethylene glycol (MEG) hei rauemi mata, mā te esterification, te transesterification rānei me te tauhohenga condensation o te whakarite i te muka polymer teitei - polyethylene terephthalate (PET), i hangaia mai i te muka mā te miro me te tukatuka muri.miro polyester, ko te roa o te miro neke atu i te kiromita o te hiraka, e takai ana ki roto i tētahi rōpū. E ai ki ngā momo whakaputa rerekē, ka wehea te miro polyester ki ngā wāhanga e toru: te miro mata, te miro totoro me te miro kakano.

I te tīmatanga o te hiraka mata

Ko te hiraka tuatahi e pā ana ki te hiraka i mirohia mā te rewa tika, kāore i totoro, e wehea ana i runga i te tere miro ki a UDY, MOY, POY me HOY.

1. Miro kāore i totoro (UDY): he koretake te aronga o ōna ngota muka, kāore hoki i whakakōkītia, nō reira he iti te kaha o tēnei momo hiraka, he roa te toronga, he iti hoki te pumau o ngā āhuatanga, ā, kāore e taea te whakamahi tika.

2. Miro Āhua-Hau-Whakaaro (MOY): he iti noa te aronga o ōna ngota muka, ā, he teitei ake te taumata aronga i te UDY, he iti iho i te miro kua whakaritea-mua. Kāore anō kia tino pumau te āhua hanganga o tēnei miro kia taea ai te whakamahi tika.

3. Waea kua whakaritea i mua (POY): kua totorohia te muka, he āhua rite te aronga me te iti o ngā kōpura moroiti, engari he iti iho i ngā whakaritenga o te waea kua oti. He iti te kaha o tēnei momo hiraka, he nui te toronga, ā, kāore i te pai mō te tukatuka tika i te papanga. Heoi, ka taea te hanga hiraka whakakotahi me ētahi atu muka hei whakatutuki i ngā hiahia raranga, kia whai momo motuhake ai te papanga.

4. Miro aronga-teitei (HOY): ka hangaia mā te miro tere-tino kotahi te taahiraa, he nui te aronga o ngā ngota muka, ā, he pai te mahi tae o te muka, engari he roa te whakaroa me te whakaheke wera, kāore e taea te whakatutuki i ngā whakaritenga whānui mō te whakamahinga.

Miro kumea

Ko te hiraka totoro e pā ana ki te muka i whiwhihia mā te totoro pakupaku o te muka i te tukanga miro. E ai ki te whānuitanga o te totoro, ka taea te wehewehe ki te hiraka totoro (DY) me te hiraka totoro katoa (FDY).

1. Hiraka totoro (DY): e pā ana ki te hiraka i hangaia mā te totoro tere-iti i roto i te tukanga miro. Ko tōna matotoru he tata ki te 40%

2. miro tino unu (FDY): e pā ana ki te miro i hangaia mā te miro me te tā i te tukanga kotahi-taahiraa. He pumau te kounga o tēnei momo miro, he iti noa ngā huruhuru, he whati ngā pito, ā, he pai te ōrite o te tae. He whānui ngā whakamahinga o āna hua, ā, he nui te kaha mākete, koinei tētahi o ngā rauemi mata matua mō ngā kakahu kāinga me ngā kakahu i Haina.

miro kakano

I raro i te mahi a ngā kaha miihini me te kaha wera, ka hurihia ngā muka torotika hei muka miro, e kiia nei ko ngā miro kakano, ko ngā muka kakano rānei. Ka taea te wehewehe ki te waea kakano tikanga (TY), te waea kakano kume (DTY) me te waea kakano hau (ATY).

1. Miro kakano tikanga (TY): ka hangaia mā te tukanga takahuri-toru o te takai -- te totoro i te miro -- te huri rūpahu te whakarerekētanga, mā te tukanga rānei o te huri tere-nui -- te huri rūpahu tere-iti, he ngāwari, he puhuruhuru, ā, he pai te pumau o te āhua.

2. miro kakano totoro (DTY): ko te tikanga, ka whakamahia te POY hei rauemi mata, ā, ka hangaia te miro iti-raro mā te totoro me te whakarerekē i te āhua o te miro mā te tukanga kotahi-taahiraa. He āhua raro tōna, ā, kāore i te tino ngawari te āhua i te TY, engari he pumau tōna kounga, ā, he kaha tōna toronga e tutuki ai ngā whakaritenga o te tango.

3. Miro kakano hau (ATY): e pā ana ki te tukatuka whakawhiti o ngā paihere tō mā te hangarau hau-rere hei hanga i te koiri piko koretake, kia whai koropiko miro puhoi ngā paihere tō. Ko te tikanga ka hangaia me te FDY hei rauemi mata, ā, ka taea hoki te hanga i ētahi hua me te POY hei rauemi mata. Ka whakamahia hoki ngā hua kua oti hei hanga papanga kakahu kāinga.

Kei roto i te momo hou o te muka miro polyester te muka rerekē, te muka mahi me te muka whakaata. I ngā tau tata nei, me te whanaketanga o te hangarau whakaata hiraka, kua whanake haere te polyester monofilament ki te muka pai, ā, ka taea te whakaputa muka tino pai me te matotoru o te raina o te 0.00011dtex.

Puna: te mātāpunenga muka matū, ngā taonga maroke kakahu.
