Mu myaka yashize, abantu bafite ibisabwa byinshi kandi bisabwa kugirango bahumurizwe n'imikorere y'imyenda y'imyenda. Hamwe no kwiyongera kwigihe cyabantu mubikorwa byo hanze, inzira yo kwinjirana no guhuza imyenda isanzwe hamwe n imyenda ya siporo nabyo birashimwa nabenshi mubaguzi. Imyenda yubwoko nkubu ntabwo isaba ihumure ryiza gusa, ahubwo isaba ko mugihe ukora, iyo umaze kubira icyuya, imyenda ntizisiga uruhu kandi ikabyara ubukonje bukabije, ibyiyumvo biremereye. Ibisabwa rero bishya byo kwinjiza amazi no gukora ibyuya bishyirwa imbere.
Nyamara, kubwo gukuramo imyenda no kubira ibyuya, abaguzi muri rusange bazayoberwa. Mubyukuri, ibi nibisobanuro bibiri, aribyo kwinjiza imyenda no gukuramo amazi.
Mbere ya byose, reka tuvuge kubyerekeranye no kwinjiza ubuhehere: fibre synthique ifata polyester nkurugero, mubyukuri, kwinjiza amazi ni ntoya, kutagira amazi meza, byoroshye kubyara ibyiyumvo byuzuye iyo bikora; Fibre karemano ifata ipamba nkurugero, imikorere yayo yo kwinjiza neza nibyiza kandi byoroshye kwambara, ariko mugihe abantu babize ibyuya bike, fibre yipamba izaguka kubera kwinjiza amazi, kandi ifatanye nuruhu, icyarimwe, amazi igipimo cyo gutandukana kiratinda, bityo bigatera ubukonje bukabije kumubiri wumuntu.
Kubwibyo, kumyenda yose, cyane cyane ibicuruzwa bya polyester, kuvura hamwe ninyongeramusaruro ya hydrophilique mugihe cyanyuma yo kurangiza ni inzira nziza yo kunoza iyinjizwa ryamazi.
Ariko iyo niyo iherezo ryayo? Ese igisubizo cyo kwinjiza amazi gikomeza uwambaye? Hygroscopic = ibyuya?
Birumvikana ko atari byo! Gusa iyo ubuhehere bwinjiye mu mwenda busohotse hejuru yigitambara uko bishoboka kwose, ubuhehere buba bwumutse neza bitewe nurumuri rwizuba hamwe numwuka uhumeka neza, bishobora gutuma uwambaye yumye kandi neza.
Gukuraho ubuhehere bwimyenda biterwa ahanini nuburyo bwa fibre. Ubushuhe bwa gaze buguruka hejuru yuruhu bwambere bwinjizwa nigitambara (ni ukuvuga hygroscopique, —- Menya ko ari umwenda hygroscopique, ntabwo ari fibre!). Noneho ingaruka ya capillary iterwa nu mwobo (pores, micropores, grooves) muri fibre kandi ikinyuranyo kiri hagati ya fibre ituma ibibyimba bitangirika kandi bigakwirakwizwa hagati yigitambara. Muri ubu buryo, ubushuhe bwimukira hejuru yigitambara bugahinduka, bityo bikarangiza inzira yo kuvanaho ubuhehere.
Noneho, kwinjiza amazi yonyine ntabwo bihagije. Kubitambara bisanzwe bisanzwe bya fibre fibre, gusa nyuma yo kurangiza hamwe ninyongeramusaruro ya hydrophilique, hanyuma bikamamazwa nka "ibyuya" bya hygroscopique mubyukuri byatuzanye twese mubwumvikane buke.
Mugukora fibre synthique, ubuso bwihariye bwa fibre burashobora kunozwa muguhindura imiterere yimyobo ya spinneret no gukora ibinogo byinshi mubyerekezo birebire bya fibre. Ibi bizamura ubushuhe bwa fibre kandi bigera kubira ibyuya binyuze mumikorere yibyingenzi byo gukuramo. Kurugero, Invista itanga polyester ya COOLMAX® hygroscopic hamwe nimpapuro zibira ibyuya. Igice cyacyo cyambukiranya ni imiterere idasanzwe, ubuso bwa fibre ni burebure mu bice bine. Ubuso bwacyo bwihariye ni 20% kurenza uruziga rusanzwe, bityo imikorere yacyo yo kubira ibyuya irenze polyester isanzwe.
Byakagombye kwitabwaho byumwihariko: Bitewe no gutunganya, igice cyambukiranya imyenda cyambaye imyenda cyangiritse cyane (bivamo guhindura plastike), bityo ingaruka zo kubira ibyuya ziragabanuka cyane. Invista nshya ya "C, C, O, O" polyester irashobora kugabanya iri hinduka rya pulasitike ku rugero runini, kugirango bigabanye ibikorwa byinshi byo kubira ibyuya --–C kuyobora umurongo ntabwo byoroshye guhinduka. Mubyongeyeho, kubakoresha, imikorere yintambara ni ngombwa, ariko ubwiza nimikorere yigitambara ni ngombwa cyane kugirango imikorere yimyenda ikorwe.
