Mucheka usina kurukwainoumbwa negwara kana shinda dzisina kurongeka.Ichi chizvarwa chitsva chezvigadzirwa zvekuchengetedza kwezvakatipoteredza, izvo zvinodzivirira hunyoro, zvinofema, zvinochinjika, chiedza, zvisingabatiki zvinotsigira, zviri nyore kuparara, zvisina muchetura uye zvisingatsamwise, zvakapfuma muruvara, mutengo wakaderera, unogona kushandiswa zvakare, nezvimwe. semuenzaniso, polypropylene (pp zvinhu) granules inonyanya kushandiswa seyakabikwa, iyo inogadzirwa nekuenderera-imwe-nhanho maitiro ekunyungudika kwekushisa kwepamusoro, kutenderera, kuisa, kupisa kudzvanya uye kukoira.Inonzi jira nekuda kwekutaridzika kwayo uye zvimwe zvinhu.
Parizvino, tambo dzakagadzirwa nevanhu dzichiri kutonga kugadzirwa kwemachira asina kurukwa, uye mamiriro ezvinhu aya haashanduke zvakanyanya kusvika 2007. 63% yemafibhi anoshandiswa mujira risiri rakarukwakugadzirwa munyika yose polypropylene, 23% polyester, 8% viscose, 2% acrylic faibha, 1.5% polyamide, uye asara 3% mamwe faibha.
Mumakore achangopfuura, kushandiswa kwemicheka isina kurukwamune zvehutsanana absorption zvinhu, zvekurapa, mota dzekufambisa, uye shangu machira zvinhu zvakawedzera zvakanyanya.
Kusimukira kwekutengeserana kwemafibhi akagadzirwa nevanhu uye kushandiswa kwehunyanzvi kwemachira asina kurukwa: Nekuda kwekugadzwa kwezvibvumirano zveupfumi hwenyika, kutengeswa kwemamicrofibers, mafiber akaumbwa, mafibhi anoodegradable uye mhando nyowani dzepolyester fiber dzakura.Izvi zvine simba guru pamachira asiri akarukwa, asi ane simba shoma pazvipfeko uye machira akarukwa.Kutsiviwa kwemicheka nezvimwe zvinhu: Izvi zvinosanganisira machira asiri akarukwa, machira ekuruka, mafirimu epurasitiki, polyurea furo, huni pulp, dehwe, nezvimwewo. Izvi zvinotariswa nemutengo uye kushanda kwezvinodiwa zvechigadzirwa.Kuunzwa kwemaitiro matsva, ane hupfumi uye anoshanda ekugadzira: iko, kushandiswa kwemachira matsva emakwikwi asiri akarukwa akagadzirwa nemapolymers, uye kuunzwa kweakakosha fiber uye asiri akarukwa machira ekuwedzera.
Iwo matatu makuru mafiber anoshandiswa mukugadzirwa kwemachira asiri akarukwa ndeye polypropylene fiber (62% yehuwandu), polyester fiber (24% yehuwandu) uye viscose fiber (8% yehuwandu).Kubva 1970 kusvika 1985, viscose fiber yainyanya kushandiswa mukugadzirwa kusina kuruka.Nekudaro, mumakore mashanu achangopfuura, kushandiswa kwepolypropylene faibha uye polyester fiber kwakatanga kutonga mumunda wehutsanana absorption zvinhu uye machira ekurapa.Mumusika wekutanga wekugadzira machira asiri akarukwa, kushandiswa kwenylon kwakakura kwazvo.Kubva 1998, kushandiswa kwe acrylic fiber kwakawedzera, kunyanya mumunda wekugadzira matehwe ekugadzira.
