Silicone softeners
Silicones yakarongedzerwa sekirasi yakaparadzana yemapolymer akaitwa nevanhu akatorwa kubva kune sili con metal muna 1904. Akashandiswa kugadzira machira ekunyorovesa makemikari kubva kuma1960.Pakutanga, unmodified polydimethylsiloxanes yakashandiswa.Mukupera kwema1970, kuiswa kweaminofunctional polydimethylsiloxanes kwakavhura zviyero zvitsva zvekupfava kwemucheka.Izwi rekuti 'silicone' rinoreva artificial polymer yakavakirwa pachimiro chealternating silicon uye oxygen (siloxane bonds).Iyo yakakura atomic radius yesilicon atomu inoita kuti silicon-silicon imwechete bond ive isina simba, nekudaro silanes (Si.nH2n+1) dzakagadzikana zvishoma pane alkenes.Nekudaro, mabhondi esilicon-okisijeni ane simba (anenge 22Kcal/mol) kupfuura kabhoni-okisijeni zvisungo.Silicone zvakare inotorwa kubva kune yayo kitone-yakafanana chimiro (silico-ketone) yakafanana neacetone.Silicones hadzina zvisungo zvakapetwa kaviri mumusana wavo uye hadzisi oxocompounds.Kazhinji, kurapwa kwesilicone kwemachira kunosanganisira silicone polymer (kunyanya polydimethylsiloxanes) emulsions asi kwete ne silane monomers, iyo inogona kusunungura makemikari ane ngozi (eg hydrochloric acid) panguva yekurapa.
Silicones inoratidza zvimwe zvakasarudzika zvinosanganisira thermal oxidative kugadzikana, kuderera kwekushisa kuyerera, kuderera kwe viscosity shanduko inopesana netembiricha, yakakwirira compressibility, kuderera kwepasi tension, hydrophobicity, yakanaka yemagetsi zvivakwa uye yakaderera moto njodzi nekuda kweiyo inorganic-organic chimiro uye kuchinjika kweiyo silicone bond. .Imwe yeakakosha maficha esilicone zvinhu kushanda kwavo pakadzika zvakanyanya.Zvishoma zvidiki zvesilicones zvinodikanwa kuti uwane izvo zvinodikanwa zvivakwa, izvo zvinogona kuvandudza mutengo wekuita machira uye kuve nechokwadi chekushomeka kwezvakatipoteredza.
Iyo nzira yekupfava nesilicone kurapwa inokonzerwa nekushanduka kwemafirimu kuumbwa.Iyo yakaderedzwa simba inodiwa pakutenderera kwebhondi inoita kuti siloxane musana uwedzere kushanduka.Kuiswa kwemafirimu anochinjika kunoderedza interfibre uye interyarn friction.
Saka iyo silicone yekupedzisa yemucheka inoburitsa yakasarudzika mubato wakapfava wakasanganiswa nezvimwe zvinhu zvakaita se:
(1) Kupfava
(2) Kusvira
(3) Muviri wakanaka
(4) Kuvandudza crease resistance
(5) Kuwedzera simba remisodzi
(6) Kunatsiridza sewability
(7) Yakanaka antistatic uye antipilling zvivakwa
Nekuda kweiyo inorganic-organic chimiro uye kuchinjika kweiyo siloxane mabhondi, silicones ine inotevera yakasarudzika zvivakwa:
(1) Thermal / oxidative kugadzikana
(2) Kudzika-kupisa kuyerera
(3) Kuchinja kwakaderera kwe viscosity nekushisa
(4) High compressibility
(5) Kuderera kwepasi pasi (kupararira)
(6) Ngozi yemoto yakaderera
Silicones ine yakafara kwazvo application mukugadzira machira, senge fiber lubricant mukuruka, anomhanya-mhanya muchina wekusonesa, mhepo uye kucheka, semasungiro mukugadzira nonwoven, seantifoam mukudhaya, seanopfavisa mukudhinda paste, kupedzisa uye kupeta.
Kunyorova kudzoreredza uye kubvumidzwa kwemakemikari fiber (sepolyester, vinylon, acrylic fiber uye naironi, nezvimwewo) zvakaderera.Asi friction coefficient yakakwira.Kupokana kunogara kuchiitwa panguva yekuruka nekuruka kunogadzira magetsi akawanda akamira.Izvo zvinodikanwa kudzivirira uye kubvisa kuunganidzwa kwemagetsi static, uye panguva imwe chete kupa iyo fiber kutsetseka uye kupfava, kuitira kuti kugadzirisa kufambe zvakanaka.Naizvozvo, panofanira kushandiswa kuruka mafuta.
Nekuvandudzwa kwemhando dzakasiyana dzekemikari faibha uye nekuvandudzwa kwemakemikari faibha kuruka mafuta uye kuruka maitiro, tsvina yakakora yasara pamachira emakemikari fiber (semafuta ekutenderera nemafuta ekuruka) yachinja zvakanyanya.Mafuta ekutenderera nemafuta ekuruka anoshandiswa nefekitari yega yega akasiyana.Mumakore achangopfuura, michina yemachira yakagadziridzwa nekukurumidza.Chiyero chemafuta chinowedzera maererano.Mamwe mafekitori akateedzera huremu hukuru hwemakemikari fiber akarukwa machira padivi, saka ivo vakawedzera dosi yemafuta.Mukuwedzera, mamwe machira emakemikari fiber akaiswa kunze, akafukidzwa netsvina yakawanda uye kusvibiswa kwemafuta.Zvese izvi zvakaunza zvimwe zvinonetsa pakubvisa mafuta mu pretreatment isati yadhayiwa nekupedzwa.
