Kubera ko inganda z’inkweto ku isi zigenda zitera imbere zigana ku ihumure, imikorere, no kurambye, inyunganiramirire y’insinga ebyiri, nk’igikoresho cy’ingenzi gishyigikira inkweto, igenda ihinduka buhoro buhoro kuva ku bikoresho biyishyigikira ikagera ku kintu cy’ingenzi mu kuvugurura ibicuruzwa. Ishingiye ku ikoranabuhanga ryayo ridasanzwe ryo kudoda insinga ebyiri, imikorere myiza ya mekanike, n’uburyo bwo kurengera ibidukikije, yakoreshejwe cyane mu nkweto za siporo, inkweto zisanzwe, inkweto z’akazi, n’inkweto zo hanze, yongera gusobanura amahame yo kumererwa neza no kuramba kw’inkweto. Inganda ziriho ubu zigaragaza icyerekezo cy’iterambere ry’ “kuvugurura imikorere, kubungabunga ibidukikije, no kwaguka kw’isoko”, kandi izongera imbaraga nshya mu iterambere ry’inganda zikora inkweto ku isi mu gihe kizaza.

Insole y'inshinge ebyiri ni ibikoresho by'umwuga byo gushyigikira inkweto byakozwe by'umwihariko ku rwego rwo hagati rw'inkweto. Ikozwe muri polyester yasubiwemo (RPET), nylon, cyangwa izindi fibre za shimi nk'ibikoresho by'ingenzi, kandi itunganywa ikanakorwa binyuze mu kudoda inshinge ebyiri no gushyushya ikoranabuhanga. Bitandukanye n'insole gakondo z'inshinge imwe zidashyigikiwe bihagije kandi zidakomeye, insole z'inshinge ebyiri zikoresha imiterere ikomeye yo kudoda inshinge ebyiri, byongerera imbaraga muri rusange no gukomera kw'ibikoresho. Si insole gakondo iboshye isaba inzira zigoye zo kuzunguruka, ahubwo ikorwa mu buryo butaziguye binyuze mu gutunganya fibre no gushimangira inshinge ebyiri, kandi yabaye igikoresho cy'ingenzi mu nganda zigezweho z'inkweto. Ubunini bwayo bushobora guhindurwa hagati ya mm 0.6 na mm 1.5 bitewe n'ubwoko butandukanye bw'inkweto n'ibyo zikenera mu mikorere, bihuye neza n'ibisabwa mu gukora inkweto zitandukanye.

Iterambere ry'imbere mu gihugu no mu mahanga rigenda ritera imbere

Isoko ry'imbere mu gihugu

Uko ibicuruzwa byinjira n’ibyoherezwa mu mahanga bihagaze: Ingano y’ibicuruzwa byoherezwa mu mahanga mu Bushinwa birimo inshinge ebyiri mu myaka yashize yariyongereye cyane, bitewe n’uko isoko ry’inkweto ku isi risaba cyane ndetse n’iterambere rikomeje ry’ikoranabuhanga rikorwa mu gihugu. Mu 2024, agaciro k’ibyoherezwa mu mahanga kageze kuri miliyari 45.8 z’amayuwani, ahanini byagurishijwe muri Aziya y’Amajyepfo y’Amajyepfo, Uburayi, Amerika y’Amajyaruguru, na Amerika y’Epfo, muri byo harimo inshinge ebyiri zikomeye cyane zagize 68% by’ingano y’ibyoherezwa mu mahanga bitewe n’uko zikoreshwa cyane n’inkweto za siporo n’inkweto zisanzwe. Biteganijwe ko igipimo cyo kohereza mu mahanga kizagera kuri miliyari 52.1 z’amayuwani mu 2025. Ibicuruzwa bitumizwa mu mahanga ahanini ni inshinge ebyiri zikora neza n’ibikoresho byo kudoda bigezweho, bishingiye ku ikoranabuhanga rigezweho ryo mu mahanga, ariko ibigo by’imbere mu gihugu birimo kwihutisha ubushakashatsi n’iterambere byigenga kugira ngo bigabanye icyuho no kongera ubushobozi bwo guhangana.

Isoko Mpuzamahanga

Ingano y'Isoko: Biteganyijwe ko mu 2025, ingano y'isoko ku isi yose ry'insinga ebyiri izagera kuri miliyari 180 z'amadolari y'Amerika, hamwe n'igipimo cy'iterambere ry'umwaka kirenga 6%. Muri 2024, ingano y'isoko ku isi yose ry'insinga ebyiri zidafite ingaruka ku bidukikije yageze kuri miliyari 89.4 z'amadolari y'Amerika, bingana na 49.7% by'isoko ryose. Bitewe na politiki yo kurengera ibidukikije ku isi ndetse n'icyifuzo cy'abaguzi ku nkweto nziza kandi ziramba, byitezwe ko izakomeza kwiyongera cyane kirenga 12% mu myaka iri imbere. Bitewe n'iterambere rikomeje ry'inganda zikora inkweto ku isi no kwiyongera kw'ivugurura ry'ibicuruzwa, icyifuzo cy'insinga ebyiri zidafite ingaruka ku bidukikije kizakomeza kwiyongera.

Itandukaniro mu mikurire y’Akarere: Akarere ka Aziya na Pasifika, cyane cyane Ubushinwa n’Ubuhinde, gafite ubushobozi bwo kwiyongera cyane, aho igipimo cy’iterambere ry’inganda zikora inkweto kirenga 8%. Bitewe n’iterambere ryihuse ry’inganda zikora inkweto no gushyigikira cyane politiki z’igihugu, icyifuzo cy’inkoni ebyiri zikozwe mu misatsi kirimo kwiyongera cyane. Amerika ya Ruguru igaragaza umuvuduko uhamye w’iterambere aho igipimo cy’iterambere kigera kuri 5%-7% buri mwaka, bitewe n’ikenerwa ryinshi ry’inkweto za siporo zigezweho n’inkweto zo hanze. Isoko ry’i Burayi ryitezweho gutera imbere buhoro buhoro kuva mu 2025 kugeza mu 2030, kandi icyifuzo cy’inkoni ebyiri zikozwe mu misatsi miremire kandi zikora neza kiziyongera buhoro buhoro hakurikijwe uburyo bwo kurengera ibidukikije n’uburyo bworoshye bwo kuruhuka. Nubwo ingano y’isoko muri Amerika y’Epfo na Afurika ari nto, rifite igipimo cy’iterambere ryihuse, rifite ubushobozi bukomeye bwo guteza imbere isoko mu gihe kizaza.

Guteza imbere ibyifuzo by'ibidukikije:

Kwita ku iterambere rirambye ku isi byateje imbere cyane inganda zikoresha insinga ebyiri. Kwibanda ku bicuruzwa bikoresha insinga ebyiri no gukaza politiki yo kurengera ibidukikije mu bihugu bitandukanye byatumye insinga ebyiri zikoresha insinga ebyiri, zikozwe mu bikoresho bishobora kongera gukoreshwa kandi bifite imyuka mike ya karuboni, biba ahantu hashya ho gukura ku isoko ry’ibikoresho by’inkweto. Urugero, amahame ya EU REACH na RoHS yashyize imbere ibisabwa mu kurengera ibidukikije ku bikoresho by’inkweto, bitanga isoko rinini ry’insinga ebyiri zikoresha insinga ebyiri. Hagati aho, isoko ry’imyenda y’umwimerere ku isi ryitezweho gukomeza kwiyongera kwa 15% buri mwaka mu 2030, ibi bikazakomeza guteza imbere inganda zikoresha insinga ebyiri zikoresha insinga ebyiri.

Politiki n'ibikenewe biragaragara, ibiranga ibidukikije biba ihame ry'irushanwa

Inkunga ikomeye ya politiki yafunguye inzira yo guteza imbere inganda zikora imisatsi ibiri. Gahunda y’ibikorwa byo kunoza ubuziranenge bw’inganda z’imyenda (2023-2025) mu Bushinwa ishyigikira neza iterambere ry’ikoranabuhanga rishya rishingiye ku binyabuzima n’ikoranabuhanga rikoreshwa mu gukora imisatsi ibiri, harimo n’imisatsi ibiri. Minisiteri y’Inganda n’Ikoranabuhanga mu Itangazamakuru, ku bufatanye na Minisiteri y’Imari, yashoye imari idasanzwe mu bushakashatsi ku ikoranabuhanga no guteza imbere no gushyira mu bikorwa inganda ikora imisatsi ibiri n’ibikoresho byayo byo hejuru, bigamije guteza imbere inganda. Muri icyo gihe, inzego z’ibanze nka Wenzhou zashyizeho politiki yo gushishikariza ibigo by’inkweto gukoresha ibikoresho bidafite VOC nyinshi kandi bitangiza ibidukikije, bitanga inkunga ya politiki yo gukwirakwiza no gukoresha imisatsi ibiri.

Ubusabe bw’abaguzi ku bijyanye n’ibidukikije n’ihumure bwakomeje kwiyongera. 67% by’abaguzi biteguye kwishyura igiciro cya 5% cyangwa kirenga ku nkweto zirimo ibikoresho bibungabunga ibidukikije. Ibigo mpuzamahanga nka Nike na Adidas byongereye cyane igipimo cy’ibikoresho bibungabunga ibidukikije mu miyoboro yabyo, kandi uburyo bwo kurinda ibidukikije n’uburyo bworohereza inyundo z’inshinge ebyiri bujyanye neza n’iyi ngendo. Igipimo cy’imigozi ya polyester ikoreshwa mu nshunge z’inshinge ebyiri cyageze kuri 38% mu 2024, kandi kizakomeza kwiyongera mu gihe kizaza, bigakomeza kunoza ipiganwa ry’ibicuruzwa ku bidukikije. Byongeye kandi, icyifuzo cy’abaguzi cy’inkweto nziza kandi ziramba cyanateje imbere kuvugurura ibicuruzwa bibungabunga inyundo z’inshinge ebyiri, kandi ibicuruzwa bikora neza nko gufata impanuka no kurwanya indwara byahindutse ahantu hakomeye ku isoko.

Umwanzuro

Muri iki gihe, inkweto ndende zo mu bwoko bwa "double needle insole" ziri mu gihe cy'ingenzi cyo "kongera impinduka mu kurengera ibidukikije, kugera ku iterambere ry'ikoranabuhanga, no kuzamura icyifuzo cy'isoko". Ibyiza byazo mu kumererwa neza, kuramba, ikiguzi, no kurengera ibidukikije byatumye inkweto ndende ziba amahitamo akomeye ku bigo bikora inkweto kugira ngo bigabanye ibiciro, byongere imikorere myiza, kandi birusheho guhangana n'ibindi bicuruzwa. Bitewe n'iterambere rihoraho ry'ubumenyi bw'ibikoresho n'impinduka zimbitse mu nganda z'inkweto, inkweto ndende zo mu bwoko bwa "double needle insole" zirimo kwaguka no kunoza ireme ry'inganda, hamwe n'icyerekezo cy'iterambere rigaragara neza.

Ku bigo by’inganda, ni ngombwa gufata ingamba zo kurengera ibidukikije no kubyaza umusaruro imikorere, no gukomeza kunoza agaciro k’ibicuruzwa n’ingaruka zabyo binyuze mu kuvugurura ibikoresho fatizo, ubushakashatsi n’iterambere ry’ikoranabuhanga, no kwagura isoko. Mu gihe kizaza, inyunganiramirire y’insinga ebyiri ntabwo izaba ibikoresho by’ingenzi gusa mu gukora inkweto, ahubwo izanagira uruhare runini mu guteza imbere iterambere rirambye ry’inganda z’inkweto no guhaza ibyifuzo by’abaguzi ku rwego rwo hejuru.
