Chifukwa Chiyani Dispersion Fastness Ndi Yosauka?

Chifukwa Chiyani Dispersion Fastness Ndi Yosauka?

Kupaka utoto kumagwiritsa ntchito kutentha kwambiri komanso kuthamanga kwambiri podaya ulusi wa polyester.Ngakhale kuti mamolekyu a utoto wobalalitsa ndi ang'onoang'ono, sikungatsimikizire kuti mamolekyu onse a utoto amalowa mu ulusi pa nthawi yopaka utoto.Utoto wina wobalalitsa umamatira pamwamba pa ulusi, zomwe zimapangitsa kusathamanga kwambiri.Amagwiritsidwa ntchito kuwononga mamolekyu a utoto omwe sanalowe mu ulusi, kukonza kufulumira, ndikuwongolera mthunzi.

Balalitsa utoto wa nsalu za poliyesitala, makamaka mumitundu yapakati ndi yakuda, kuti achotseretu mitundu yoyandama ndi oligomers otsalira pamwamba pa nsalu ndikuwongolera kufulumira kwa utoto, nthawi zambiri ndikofunikira kuchita kuyeretsa kochepetsera pambuyo popaka utoto.

Nsalu zosakanikirana nthawi zambiri zimatanthawuza ulusi wopangidwa ndi zigawo ziwiri kapena zingapo zosakanikirana, choncho nsaluyi ili ndi ubwino wa zigawo ziwirizi.Ndipo pokonza chiŵerengero cha chigawocho, makhalidwe ambiri a chimodzi mwa zigawozo angapezeke.

Kusakaniza nthawi zambiri kumatanthauza kusanganikirana kwa ulusi, ndiko kuti, ulusi uŵiri wa zigawo zosiyanasiyana umasakanizidwa pamodzi monga ulusi waukulu.Mwachitsanzo: nsalu ya polyester-thonje yosakanikirana, yomwe nthawi zambiri imatchedwa T / C, CVC.T/R, etc. Amalukidwa ndi kusakaniza kwa polyester staple fiber ndi thonje ulusi kapena ulusi wopangidwa ndi anthu.Ubwino wake ndi: ali ndi mawonekedwe ndi kumverera kwa nsalu zonse za thonje, amafooketsa mankhwala CHIKWANGWANI luster ndi mankhwala CHIKWANGWANI kumverera kwa polyester nsalu, ndi bwino mlingo.

Kuthamanga kwamtundu wamtundu, chifukwa nsalu ya polyester imakhala ndi utoto wotentha kwambiri, kufulumira kwamtundu ndikwapamwamba kuposa thonje, kotero kufulumira kwa utoto wansalu yosakanikirana ya thonje ya polyester imakhalanso bwino poyerekeza ndi thonje.

Komabe, kuti nsalu za thonje za poliyesitala zikhale zolimba, ziyenera kuchepetsedwa (zomwe zimatchedwa R/C) ndikuthira mankhwala pambuyo popaka utoto ndi kubalalitsidwa.Kuthamanga kwamtundu koyenera kungapezeke kokha pambuyo pochepetsa ndi kuyeretsa.

Kuphatikizika kwa ulusi wamtundu uliwonse kumathandizira kuti mawonekedwe a gawo lililonse awonetsedwe mofanana.Momwemonso, kuphatikiza zinthu zina kungathenso kuchita zabwino zawo kuti zikwaniritse zofunikira zina, zotonthoza kapena zachuma.Komabe, nsalu zophatikizika za poliyesitala ndi thonje zimamwazikana ndikudayidwa pa kutentha kwakukulu.Yapakatikati, chifukwa cha kusakanikirana kwa thonje kapena rayon CHIKWANGWANI, ndipo kutentha kwa utoto sikungakhale kwakukulu kuposa kutentha kwa nsalu ya polyester.Komabe, nsalu za polyester-thonje kapena polyester-thonje rayon, pansi pa kukondoweza kwa alkali amphamvu kapena sodium hydroxide, zidzachititsa kuti mphamvu ya fiber kapena mphamvu yong'ambika igwe kwambiri, ndipo zimakhala zovuta kukwaniritsa khalidwe la mankhwala muzogwirizanitsa zotsatila.

Njira yosinthira kutentha kwa utoto wobalalitsa imatha kufotokozedwa motere:

1. Pakupanga utoto wotentha kwambiri, kapangidwe ka poliyesitala kamakhala kotayirira, utoto wobalalitsa umasiyana kuchokera pamwamba pa ulusi kulowa mkati mwa ulusi, ndipo makamaka umagwira pa polyester fiber ndi hydrogen bond, dipole kukopa ndi van der. Waals mphamvu.

2. Ulusi wopakidwa utoto ukakhala ndi kutentha kwapamwamba kwambiri, mphamvu yotenthetsera imapatsa mphamvu yogwira ntchito kwambiri ku unyolo wautali wa poliyesitala, womwe umakulitsa kugwedezeka kwa unyolo wa mamolekyulu, ndipo mawonekedwe a ulusiwo amamasukanso, zomwe zimapangitsa mgwirizano pakati pawo. mamolekyu ena a utoto ndi unyolo wautali wa poliyesitala Wafooka.Chifukwa chake, mamolekyu ena a utoto okhala ndi mphamvu zambiri zochitira zinthu komanso kudziyimira pawokha kwapamwamba amasuntha kuchokera mkati mwa ulusi kupita kumalo osanjikiza omwe ali ndi mawonekedwe otayirira, kuphatikiza ndi ulusi kuti apange utoto wosanjikiza.

3. Pa nthawi ya kunyowa kusala kudya.Mitundu yapamtunda yomwe siimangiriridwa mwamphamvu, ndi utoto womwe umamatira ku chigawo chomata cha thonje, udzasiya mosavuta ulusi kuti ulowe mu yankho ndikuipitsa nsalu yoyera;kapena kumamatira mwachindunji ku nsalu yoyera yoyesera popaka, motero kusonyeza kufulumira kwamadzi ndi kukangana kwa mankhwala opaka utoto kufulumira kumachepa.
