Polyester (polyester fiber), imwe mu nsinga zikozwe cane kw’isi, yacitse ikintu nyamukuru mu bijanye n’ubuhinga bwo gukora imyenda kubera ubushobozi bwayo bwiza cane bwo ku mubiri no ku buhinga, ukudahinduka kw’imiti, n’ugukora neza. Ivyo ikora vyatumye igira ikibanza kidashobora gusubirizwa mu bijanye n’impuzu, ivy’impuzu zo mu nzu be n’ivy’inganda.
I. Inyungu z'ishimikiro z'ibikorwa
1. Inkomezi nyinshi n'Uguhangana n'Ibikomere
Inkomezi za polyester zo guca ibice zishobora gushika kuri 3,5-5,0 cN/dtex, ni ukuvuga incuro zibiri canke zitatu z’insinga z’ibimera, kandi ubushobozi bwayo bwo guhangana n’ugusenyuka ni ubwa kabiri inyuma ya nylon. Ivyo bituma ikoreshwa cane nk’impuzu zo ku kazi, ibikoresho vyo hanze, n’amatapi.
2. Ugukomera neza cane
Polyester ifise umubare munini w’intango (hafi 90-120 cN/dtex), bikaba bituma ihinduka bikeyi iyo iteye umubabaro kandi igakomeza neza cane. Naho yoba yarambuwe 10%, irashobora gusubira uko yari imeze, ivyo bikaba bituma ikoreshwa cane mu mpuzu zisaba ko zifata neza, nk’amashati n’amakoti.
3. Uguhangana n'imiti bidasanzwe
Igaragaza ubushobozi bwinshi bwo guhangana n’aside (uretse aside nitrique yihariye), alkali (ishobora guhangana n’ibinyabuzima bigoyagoya mu bushuhe bwo mu cumba), n’ibintu bitera umuriro, kandi igaragaza ubushobozi bwo guhangana n’ibintu bitera umuriro ugereranije n’insinga z’ibinyabuzima. Ivyo bituma ikoreshwa cane mu bikoresho vyo kuyungurura, mu mpuzu zo kwikingira no mu bindi bikorwa.
II. Ibirango bikora n'amahitamwo yo guhindura
1. Ugushikama kw'ubushuhe n'ingero
Polyester ifise ubushuhe bwo guhindura ikiyo bugera kuri degre 67-81 . Gushushanya gatoyi ku bushuhe bwa degre 150 bituma gusa bigabanuka, mu gihe ukubora gutangura ku bushuhe bwa degre 240 . Ubushobozi bwayo bwo gufata amazi buke (ubukonje bushobora gusubira mu mazi bwa 0,4%) butuma iyo mpuzu ishobora gukura cane (mu bisanzwe ikaba iri munsi ya 2%), ivyo bikaba bituma ishobora gukoreshwa mu mpuzu zisaba ko zifata neza.
2. Kwitwararika vyoroshe
Kubera ko idakunda amazi, ituma idashobora gutera imitsi- kandi ikaba yoroshe gukomera, ariko ubukonje bwayo bwo gufata ubukonje n’uguhema ni buke cane. Guhindura ibice bidasanzwe vy’umusaraba- (nk’imiterere y’umusaraba n’imiterere y’imirongo itanu) birashobora gutuma ubukonje bushobora gufata neza no kwuma ningoga, mu gihe ubuhinga bwo gutera ifu bushobora gutuma ubushuhe bugumaho.
3. Ukwaguka kw'ibikorwa
Guhindura copolymerization bishobora gutanga ubushobozi bwo guhangana n’imishwarara ya UV, ubushobozi bwo kurwanya imigera, n’imishwarara ya kure-infrared. Ubuhinga bwo gucapura bukozwe mu bihimba vy’umubiri (nk’umurongo wa polyester/spandex-ubudodo bwo gucapura) burahuza ugutambagira no kugumya imiterere.
3. Guhindura ibikorwa
Polyester ihura n’ivyo umuntu akeneye bitandukanye biciye mu gutunganya ibintu bitandukanye: polyester isanzwe ikoreshwa mu mpuzu z’imideri yihuta; polyester ikomeye cane-ikoreshwa mu migozi no mu mikanda y’umutekano; kandi ultra-fine denier polyester (urudodo rumwe ruri munsi canke rungana na 1 dtex) ni rwo ruhitamwo rwiza ku mpuzu zimeze nk’ubudodo bw’agaciro kanini-.
Mu gihe kizoza, n’uguteza imbere ubuhinga bwa polyester bushingiye ku binyabuzima (bio-) n’ubuhinga bwo guhindura ubushuhe, iki gikoresho ca kera kizobandanya kurongora ubuhinga bushasha mu bijanye n’impuzu.
