Ifu y'ikinyabutabire, izwi kandi nka "chemical fiber resin interlining", ni ibikoresho by'ingenzi byagenewe gutunganya no gukomeza inkweto n'agatsinsino. Bitandukanye n'ifu y'ikinyabutabire isanzwe y'uruhu isaba kwinjizwa mu mazi kugira ngo yoroshye kandi ishongeshe neza iyo ishyushye, ifu y'ikinyabutabire ishingiye kuri polymeri zikoze mu byuma nka polyvinyl chloride (PVC) na polyurethane (PU). Ikiranga cyayo cy'ingenzi ni uko yoroha iyo yinjijwe mu bintu bisukura ibinyabuzima nka toluene kandi igakomera nyuma yo kuma, igakora imiterere ikomeye ku mano no ku gatsinsino. Nk' "umugongo w'inkweto", igira uruhare rudasimburwa mu kubungabunga imiterere y'inkweto mu mpande eshatu, ikarinda kugwa no kwangirika, no kongera uburyohe no kuramba.

Politiki Mpuzamahanga zijyanye n'ibi

Ku rwego mpuzamahanga, amategeko akaze agenga ibidukikije n'umutekano yabaye imbaraga zikomeye mu guhindura inganda zikora imiti. Ishami ry’Umuryango w’Ubumwe bw’u Burayi ryiyandikisha, risuzuma, ryemerera kandi ribuza imiti (REACH), cyane cyane Annex XVII, rishyiraho imipaka ikomeye ku bintu biteza akaga mu bikoresho bya shimi, bitwikiriye ibyuma biremereye nka chromium hexavalent, cadmium na lead, ndetse n’ibintu by’umwimerere nka formaldehyde, phthalates na per- na polyfluoroalkyl substances (PFAS).
Politiki zo kubungabunga ibidukikije ku bijyanye n’imiti ikoreshwa mu gusiga ibitoki ku masoko yo mu gihugu no mu mahanga ntizateje imbere ibidukikije gusa, ahubwo zanatumye abaturage barushaho kwizera imiti ikoreshwa mu gusiga ibitoki ku bitoki. Muri iki gihe, aho ibidukikije bikomeje kwiyongera, kunoza politiki byatumye isoko rikenera cyane kandi bigateza imbere iterambere ry’ibigo.

Isesengura rya Amasoko Mpuzamahanga ku Isi
Isoko ry’ibinyobwa bikozwe mu mpu z’imiti rifitanye isano rya hafi n’inganda zikora inkweto n’imitako yoroheje, rikomeza kwiyongera gukomeye bitewe n’ingufu zikenewe. Nk’uko raporo z’ubushakashatsi ku isoko zibigaragaza, ingano y’isoko ry’ibinyobwa bikozwe mu mpu z’imiti ku isi yageze kuri miliyari 1.28 z’amadolari y’Amerika mu 2024 kandi biteganijwe ko rizagera kuri miliyari 1.86 z’amadolari y’Amerika mu 2029, hamwe n’igipimo cy’izamuka ry’ibiciro ku mwaka (CAGR) kingana na 7.8%. Ku bijyanye n’ikwirakwizwa ry’ibinyobwa mu karere, akarere ka Aziya na Pasifika kagize 42% by’isoko ku isi, aho Ubushinwa, Ubuhinde n’ibihugu byo muri Aziya y’Amajyepfo y’uburasirazuba ari byo bitera imbere cyane; Amerika ya Ruguru ifite 28%, Uburayi bufite 22%, n’utundi turere twose hamwe 8%. Ku isoko mpuzamahanga, abakora ibicuruzwa bikomeye barimo ibigo mpuzamahanga by’imiti nka BASF yo mu Budage na DuPont yo muri Leta Zunze Ubumwe za Amerika, bibanda ku bicuruzwa by’imiti bikozwe mu mpu z’imiti bigamije isoko ry’inkweto zo hagati n’izo ku rwego rwo hejuru.

Gupima Ikiguzi n'Imikorere
I. Imikorere myiza cyane: 
Ifite Ishusho Ikomeye, Ihuza n'Inzira Zitandukanye Ifu y'ikirenge ifite ubukana n'ubufasha bwiza.

Nyuma yo kumera neza, ifite imbaraga nyinshi zo gukurura no kudacika. Nubwo yambara igihe kirekire, ishobora kugumana imiterere ihamye y'inkweto nta guhindagurika. Hagati aho, ifite ubushobozi bwo guhangana n'ikirere no kudahinduka kw'amabara, kandi ntigira ingaruka ku bintu byo hanze nk'imvura n'ibyuya.

Ubukomere bwayo bushobora guhindurwa mu buryo bworoshye binyuze mu buryo bwo gushushanya inkweto kugira ngo zihuze n'ibyo inkweto zitandukanye zikeneye: inkweto zikomeye zifite ubufasha bukomeye kandi zikwiriye inkweto ndende zifite imiterere miremire; inkweto zoroshye zifite imiterere myiza kandi zishobora guhuza neza n'inkweto zisanzwe.

Ku bijyanye n'imikorere, iki gikoresho ntigisaba ibikoresho byihariye by'umwuga. Uburyo bwo gushushanya bushobora kurangizwa binyuze mu buryo bworoshye nko kuvoma mu mazi kugira ngo yoroshye, kuyashyira mu buryo bwo kuyashushanya, no kuyumisha mu buryo busanzwe. Ingano y'uburyo bwo gukora ni nto, bigatuma inganda nto n'iziciriritse zoroherwa no kuyakoresha vuba mu byiciro.

II. Ahantu hanini ho gusaba:
Kwibanda ku bikoresho by'inkweto, kwagura imipaka. Gukoresha sheet sheet toe puff byibanda ku bikoresho by'inkweto, bikubiyemo ibikoresho bitandukanye by'inkweto nk'inkweto z'uruhu z'abagabo n'abagore, inkweto za siporo, inkweto z'ingendo, inkweto n'inkweto z'umutekano.

Ikoreshwa cyane cyane mu gutunganya no gukomeza agasanduku k'amano n'agatsinsino, kandi ni ibikoresho by'ingenzi bifasha mu kubungabunga imiterere y'inkweto mu mpande eshatu. Muri icyo gihe, imiterere yayo ishobora kwaguka no mu zindi nzego. Ishobora gukoreshwa nk'ibikoresho byo gushyigikira imitwaro, imitako y'ingofero n'amakori, ndetse no mu gukomeza no gutunganya utuntu duto nk'udupira two mu bikoresho, kwagura imbibi z'uburyo bwo kuyikoresha.

Ku bijyanye n'uburyo butandukanye bwo gukoresha, hari ubwoko butandukanye bw'imiti ikoreshwa mu gupfuka inkweto: urugero, HK666 ikwiriye inkweto zo kwiruka, zishobora kongera ubushobozi bwo guhangana n'inkundura y'urutoki; HK (L) ikwiriye inkweto z'umupira w'amaguru n'inkweto zirinda umutekano kugira ngo ihuze n'ibikenewe mu mikino ikomeye no kurinda akazi; HC na HK (umukara) zikwiriye inkweto zisanzwe n'inkweto zirambuye, zifite imiterere ihamye kandi zigakwirakwira.

III. Ibyiza by'ingenzi ku irushanwa:
Ubwiza n'igiciro gito, bigabanya ibiciro kandi bikongera imikorere myiza
1. Gukomera cyane: Nyuma yo gufatanya n'ibindi bikoresho by'inkweto nk'uruhu, igitambaro na rabha, ntabwo byoroshye kubigabanya cyangwa ngo biveho, bigatuma imiterere y'inkweto muri rusange iramba.
2. Ingaruka zo Kurema Ishusho Irambye: Ifite imbaraga zirambye, ishobora kugumana inkweto zigororotse kandi zidafite iminkanyari igihe kirekire, kandi ikanoza ubwiza n'ubuzima bw'ibicuruzwa.
3. Umupaka muke wo gukora: Nta mpamvu yo gushora imari mu bikoresho bihenze, koroshya inzira yo gukora, no kugabanya ikiguzi cy'ishoramari ry'abakozi n'ibikoresho by'ibigo.
4. Uburyo bwo kugabanya ikiguzi: Ugereranyije n'ibindi bisa nka hot-melt adhesive toe puff, ifite ikiguzi gito cyo kuyikora, ikwiriye gukorwa ku bwinshi, kandi ishobora gufasha ibigo by'inkweto kugenzura neza ibiciro no kongera ipiganwa ku isoko.

Uburyo ba rwiyemezamirimo ba "Chemical Sheet Toe Puff" bashobora kumenyera iterambere ry'ejo hazaza
Bahanganye n'amategeko akaze agenga ibidukikije n'irushanwa ku isoko, ba rwiyemezamirimo bagomba gufata ingamba zo guhindura ibintu: Kwihutisha ubushakashatsi n'iterambere ku bicuruzwa bibungabunga ibidukikije: kugabanya kwishingikiriza kuri PVC, gushora imari muri PU, polyester ishingiye ku binyabuzima na PLA ibora, no guteza imbere uburyo bwo gukora ibintu bidafite solvent/low VOC kugira ngo bihuze n'amahame mpuzamahanga. Kuzamura ikoranabuhanga mu gukora: gushyiraho uburyo bwo gukora ibintu bugezweho kugira ngo habeho ireme rihamye no kongera gukoresha ibikoresho mu buryo bufunze kugira ngo hagabanywe imyuka ihumanya ikirere. Komeza ubufatanye mu nganda: fatanya n'abatanga ibikoresho fatizo ku bikoresho bibungabunga ibidukikije n'ibirango by'inkweto ku bicuruzwa byihariye kugira ngo hubakwe inyungu zitandukanye. Gushyiraho uburyo bwo kubahiriza amategeko ku isi: gukurikirana REACH, CPSIA n'andi mategeko kugira ngo harebwe ko ibicuruzwa byemejwe kandi hirindwe ingaruka zo kugera ku isoko. Kwagura amasoko mashya: koresha ibisabwa mu bihugu bya Belt and Road no mu turere dushya tw'inganda kugira ngo wongere agaciro k'ibicuruzwa bibungabunga ibidukikije.

Umwanzuro 
Nk'ibikoresho bisanzwe kandi by'ingenzi mu nganda z'inkweto, icyuma gishyushya ibitoki cya shimi cyashyizeho urufatiro rukomeye rwo gutunganya inkweto no kuzigama ubuziranenge hamwe n'imikorere ihamye n'inyungu zacyo. Mu gihe isi yibanda ku kurengera ibidukikije no kuvugurura imikoreshereze yazo, uru ruganda rurimo guhangana n'igihe gikomeye cyo guhinduka kuva ku "giciro" kugera ku "giciro". Nubwo ibicuruzwa gakondo biri munsi y'igitutu cy'amahame n'irushanwa ku isoko, isoko ry'icyuma gishyushya ibitoki cya shimi cyahinduwe kandi gifite imikorere myiza rikomeje kwaguka. Bitewe n'udushya mu ikoranabuhanga n'ubuyobozi bwa politiki, urwego rw'icyuma gishyushya ibitoki rwa shimi ruzajya rutera imbere buhoro buhoro rugana ku kurengera ibidukikije, ubwenge n'iterambere ry'agaciro kanini. Ku ba rwiyemezamirimo, ni ugukurikiza iterambere rishingiye ku guhanga udushya, gusubiza mu buryo buhamye impinduka mu mategeko no kongera imikoranire y'inganda, bashobora gukoresha amahirwe y'isoko mu gihe cy'impinduka, bagakomeza guhangana, kandi bagakomeza kugira uruhare runini mu ruhererekane rw'inkweto ku isi..
