Sechinhu chinoshanduka chinozivikanwa nekunyaradza uye kuita zvakasiyana-siyana,micheka yakarukwavakawana kushandiswa kwakakura muzvipfeko, zvishongedzo zvemba, uye zvipfeko zvekudzivirira zvinoshanda. Nekudaro, machira echinyakare machira anowanzo kuve anopfuta, asina kupfava, uye anopa kushomeka kwekudzivirira, izvo zvinotadzisa kutorwa kwavo kwakakura. Kuvandudza iyo inodzivirira moto uye yakagadzika zvimiro zvemicheka yave nzvimbo yekutarisa muindasitiri. Nekusimbisa kuri kukura pamachira e-akawanda-anoshanda uye machira anoyevedza akasiyana, zvese zvedzidzo neindasitiri zviri kuedza kugadzira zvinhu zvinosanganisa kunyaradza, kuramba kwemoto, uye kudziya.
Parizvino, vazhinjimicheka isingadziviriri murazvozvinogadzirwa uchishandisa angave anodzoreredza murazvo coatings kana composite nzira. Micheka yakavharwa inowanzova yakaoma, inorasikirwa nemoto wekudzivirira mushure mekugeza, uye inogona kuderedza kubva pakupfeka. Zvichakadaro, machira akaumbwa, kunyangwe asingadziviri murazvo, kazhinji akakora uye haafemeke, achipa kunyaradza. Kuenzaniswa nemachira akarukwa, machira anongogara akapfava uye akanyanya kugadzikana, izvo zvinovabvumira kushandiswa senge base layer kana chipfeko chekunze. Machira akarukwa anodzivirira murazvo, akagadzirwa achishandisa mafizi asingadziviriri murazvo, anopa dziviriro yemurazvo wakasimba pasina kumwe kurapwa mushure uye kuchengetedza kunyaradzwa kwawo. Zvisinei, kugadzira rudzi urwu rwejira kwakaoma uye kunodhura, sezvo yakakwirira-inodzivirira moto-inodzivirira fibers se aramid inodhura uye inonetsa kushanda nayo.
Zvichangobva kuitika zvakakonzeramicheka yakarukwa isingapindi mumoto, kunyanya kushandisa tambo dzepamusoro-soro senge aramid. Nepo machira aya achipa yakanakisa murazvo kuramba, kazhinji anoshaya kuchinjika uye kunyaradza, kunyanya kana akapfekwa padivi peganda. Kurukwa kwemafibhi asingapindi murazvo kunogonawo kunetsa; kuomarara kwepamusoro uye kusimba kwesimba remafibhi asingapindi murazvo kunowedzera kuoma kwekugadzira machira akarukwa akapfava uye akasununguka. Nekuda kweizvozvo, machira akarukwa asingasviki murazvo haawanzo kuwanikwa.
1. Core Knitting Process Design
Iyi purojekiti inoda kugadzira ajiraiyo inobatanidza kuramba kwemurazvo, anti-static zvivakwa, uye kudziya uku ichipa nyaradzo yakakwana. Kuti tiwane zvinangwa izvi, takasarudza chimiro chemvere dzemaviri-mativi. Iyo shinda yepasi ndeye 11.11 tex-inodzivirira polyester filament, nepo loop yarn iri musanganiswa we28.00 tex modacrylic, viscose, uye aramid (mu50:35:15 reshiyo). Mushure memiedzo yekutanga, isu takatsanangura ekutanga kuruka maratidziro, ayo akatsanangurwa muTebhu 1.
2. Process Optimization
2.1. Mhedzisiro yeLoop Length uye Sinker Height pane Fabric Properties
Kuramba kwemurazvo kwejirazvinoenderana nezvose zvinopisa zvimiro zvefiber uye zvinhu zvakaita semachira maumbirwo, ukobvu, uye mhepo. Mumachira akarukwa-weft, kugadzirisa kureba kwechiuno uye kureba kwekunyura (loop urefu) kunogona kukanganisa moto kuramba uye kudziya. Ichi chiedzo chinoongorora mhedzisiro yekusiyanisa aya ma paramita kuti akwidzise mirazvo yekudzivirira uye kudzivirira.
Tichiyedza misanganiswa yakasiyana yehurefu hwechiuno uye kureba kwekunyura, takaona kuti apo kureba kweshinda yeshinda yaive 648 cm, uye kureba kwekunyura kwaive 2.4 mm, huremu hwejira hwaive 385 g/m², iyo yakapfuura huremu hweprojekiti. Neimwe nzira, ine base yarn loop kureba kwe698 cm uye inonyura kureba kwe2.4 mm, jira racho rairatidza rakasununguka chimiro uye kudzikama kutsauka kwe -4.2%, iyo yakawira pasi pezvainotarirwa. Iyi nhanho yekugonesa yakavimbisa kuti yakasarudzwa loop kureba uye kureba kwekunyura kwakasimudzira zvese kumira kwemurazvo uye kudziya.
2.2.Migumisiro YemuchekaKuvhara paFlame Resistance
Iyo yekuvhara nhanho yejira inogona kukanganisa kumira kwayo murazvo, kunyanya kana tambo dzepasi dziri polyester filaments, iyo inogona kugadzira madonhwe akanyunguduka panguva yekupisa. Kana kuvhara kusina kukwana, jira rinogona kutadza kuzadzisa mitemo yekudzivirira moto. Zvinhu zvinofurira kufukidzwa zvinosanganisira warn twist factor, yarn material, sinker cam settings, tsono hook shape, uye machira ekutora tension.
Iko kutora-up tension inokanganisa kuvhara kwejira uye, naizvozvo, kuramba kwemoto. Kutora-up tension inotungamirwa nekugadzirisa giya reshiyo mune yekudhonza-pasi meshini, iyo inodzora nzvimbo yeshinda muhoko yetsono. Kuburikidza negadziriso iyi, takakwenenzvera kufukidzwa kweshinda yechiuno pamusoro pechigadziko cheshinda, tichidzikisa maburi anogona kukanganisa kuramba kwemurazvo.
3. Kuvandudza Kuchenesa System
High-speeddenderedzwa knitting michina, nekuwanda kwenzvimbo dzadzo dzekudyisa, dzinobudisa lint yakawanda uye huruva. Kana zvikasabviswa nekukasira, izvi zvinosvibisa zvinogona kukanganisa kunaka kwemachira uye kuita kwemuchina. Tichifunga kuti loop yarn yepurojekiti musanganiswa we28.00 tex modacrylic, viscose, uye aramid mapfupi mafiber, shinda yacho inodonha yakawanda, inogona kuvhara nzira dzekudyisa, zvichikonzera kuputika kweshinda, uye kugadzira kukanganisa kwemachira. Kuvandudza hurongwa hwekuchenesa padenderedzwa knitting michinazvakakosha pakuchengetedza hutano nekubudirira.
Nepo michina yekuchenesa yakajairwa, senge mafeni nemafuridziro emhepo akadzvanywa, ichishanda mukubvisa lint, inogona kunge isingakwani kune shinda-pfupi-fiber, sezvo lint buildup inogona kukonzera kazhinji kuputika kweshinda. Sezvinoratidzwa muMufananidzo 2, isu takasimudzira mhepo yekufambisa nekuwedzera huwandu hwemanozzles kubva paina kusvika kumasere. Ichi chigadziriso chitsva chinobvisa zvinobudirira guruva uye lint kubva munzvimbo dzakakosha, zvichikonzera kushanda kwakachena. Kuvandudzwa kwacho kwakaita kuti tiwedzerekuruka kumhanyakubva 14 r/min kusvika 18 r/min, zvakanyanya kuwedzera kugadzirwa kwesimba.
Nekukwenenzvera kureba kweloop uye kureba kwekunyura kuti uwedzere kuramba kwemoto uye kudziya, uye nekuvandudza kufukidzwa kunosangana nemirazvo-yekudzivirira miyero, takawana yakagadzikana nzira yekuruka inotsigira yaidiwa zvivakwa. Iyo yakakwidziridzwa yekuchenesa sisitimu zvakare yakaderedza zvakanyanya kuputika kweshinda nekuda kwekuvakwa kwe lint, kuvandudza kugadzikana kwekushanda. Iyo yakakwidziridzwa yekugadzira yekumhanyisa yakasimudza iyo yekutanga kugona ne28%, ichidzikisa nguva dzekutungamira uye kuwedzera kuburitsa.
