Ni ubuhe bwoko bw'imyenda idafunze?
Ibikoresho Bidafunze Bikozwe mu Myege
Ugereranyije n'izindi koranabuhanga zitari izo mu bwoko bwa "nonwovens", "airlaid" ifite ubushobozi bwihariye bwo gushyira hasi imigozi migufi, yaba imigozi ya pulp 100%, cyangwa uruvange rw'imigozi ya pulp n'imigozi ya "synthetic" ikozwe mu buryo burambuye kandi buhoraho. Birashoboka kandi kuvanga ifu cyangwa imigozi ifata cyane bityo bigatuma habaho imigozi ifata cyane.

Guhuza umwuka binyuze mu kirere (Guhuza ubushyuhe)
Guhuza umwuka binyuze mu mwuka ni ubwoko bw'ubushyuhe busaba gushyira umwuka ushyushye hejuru y'umwenda utari uwo kuboha. Mu gihe cyo guhuza umwuka binyuze mu mwuka, umwuka ushyushye unyura mu myobo iri hejuru y'ikintu kitari uwoboha.

Ihindagurika ry'ikirere
Udupira tudakozwe mu buryo bwa Meltblown dukorwa binyuze mu gusohora insinga za polymer zishongeshejwe binyuze mu muyoboro cyangwa umuyoboro ugizwe n'imyobo 40 kuri santimetero imwe kugira ngo hakorwe insinga ndende zoroshye zinyuzwamo umwuka ushyushye hejuru y'insinga iyo ziguye mu muyoboro. Urusobe ruvamo rukusanyirizwa mu migozi hanyuma rugahindurwamo ibikoresho byarangiye.

Spunlace (Hydrotentanglement)
Spunlace (izwi kandi nka hydroentanglement) ni uburyo bwo guhuza imigozi y’imigozi y’ubudodo butose cyangwa bwumye bukozwe hakoreshejwe uburyo bwo gushyiramo udupira, gushyiramo umwuka cyangwa gushyiramo udupira, hanyuma umwenda uboshye ukaba utari uwo kuboha. Ubu buryo bukoresha amazi meza kandi afite umuvuduko mwinshi yinjira mu ihema, agakubita umukandara (cyangwa "insinga" nk'uko bigenda mu gukora impapuro) hanyuma agasubira inyuma bigatuma imigozi ifatana. Spunlace imigozi idakoze ikoreshwa mu migozi migufi, ikunzwe cyane ni imigozi ya viscose na polyester ariko polypropylene na ipamba nabyo birakoreshwa. Imikoreshereze y'ingenzi ya spunlace irimo imyenda yo kwihanagura, udupfukamunwa two mu maso n'ibindi bikoresho by'ubuvuzi.

Spunlaid (Spunbond)
Ibikoresho bita Spunlaid, kandi byitwa spunbond, bikorerwa mu buryo bumwe buhoraho. Fibres zirazunguruka hanyuma zigakwirakwizwa mu buryo butaziguye mu rushundura n'ibikoresho bizihindura cyangwa zishobora kuyoborwa n'imigezi y'umwuka. Ubu buryo butuma umuvuduko w'umukandara wihuta, kandi bigatuma amafaranga agabanuka.

Gushonga/ubutumwa bugufi
Spunbond yahujwe n'udutambaro two mu bwoko bwa melt-blown nonwovens, bituma tuyihinduramo ubwoko bw'ibikoresho byiswe SMS (spun-melt-spun). Udutambaro two mu bwoko bwa melt-blowns dufite uburebure buto cyane bwa fibre ariko si imyenda ikomeye. Udutambaro twa SMS, twakozwe muri PP gusa, ntitwirinda amazi kandi ni tworoshye ku buryo dushobora gukoreshwa nk'imyenda ikoreshwa rimwe gusa. Melt-blowns ikunze gukoreshwa nk'ibikoresho byo kuyungurura, ikaba ishobora gufata uduce duto cyane. Spunlaid ihuzwa na resin cyangwa ubushyuhe.

Ikibaya cy'amazi
Mu gikorwa cyo gucukura amazi, imigozi y’ingenzi ifite uburebure bwa mm 12, akenshi ivanze na viscose cyangwa impumuro y’ibiti, ishyirwa mu mazi, hakoreshejwe ibigega binini. Nyuma y’aho imigozi y’amazi cyangwa impumuro y’amazi irasukwa kandi igakomeza gushyirwa ku nsinga ikora. Amazi arakurwamo, akayungururwa kandi agakoreshwa. Uretse imigozi y’ubukorikori, imigozi ya ceramic na karuboni irashobora gutunganywa.
