Ipolypropylene engalukwanga vs ipolyester

Amalaphu angalukwanga awawo amalaphu alukiweyo, kodwa aqulunqwe ngolungelelwaniso lwefiber ejongisiweyo okanye engacwangciswanga, ngoko ke ikwabizwa ngokuba ngamalaphu angalukwanga. Ngenxa yezixhobo ezahlukeneyo kunye neenkqubo zemveliso, amalaphu angalukwanga angohlulwa abe ziindidi ezininzi, ezifanaiilaphu zepolyester ezingalukwanga, amalaphu e-polypropylene angalukwanga, njl.

Abathengi bahlala bebuza ngomahluko phakathi kwelaphu lepolyester elingalukwanga, ilaphu elingalukwanga elinepolypropylene, ifayibha yepolypropylene, kunye nepolyester xa bejongana neemveliso zelaphu ezingalukwanga. Apha ngezantsi kukho uluhlu lweeyantlukwano zabo.

Ilaphu elingalukwanga le-PET

Ilaphu le-PET spunbond filament elingalukwanga luhlobo lwelaphu eligxotha amanzi elingalukwanga, kwaye ukusebenza kwayo kokugxotha amanzi kuyahluka ngokuxhomekeke kubunzima belaphu. Ubukhulu kunye nobukhulu ubunzima, ngcono ukusebenza kwamanzi okugxotha. Ukuba kukho amaconsi amanzi kumphezulu welaphu elingalukwanga, amathontsi amanzi aya kutyibilika ngokuthe ngqo kumphezulu.

Ilaphu lePolyester elingalukwanga liyakwazi ukumelana nobushushu obuphezulu. Ngenxa yokunyibilika kwepolyester ijikeleze i-260 ° C, inokugcina uzinzo lwemilinganiselo yangaphandle yamalaphu angalukwanga kwiindawo ezifuna ukumelana nobushushu. Isetyenziswe ngokubanzi ekushicileleni ukushisa, ukuhluzwa kweoli yokuhambisa, kunye nezinye izinto ezidibeneyo ezifuna ukumelana nobushushu obuphezulu.

PET spunbond ilaphu non-elukiweyoluhlobo lwelaphu elingalukwanga elenziwe ngelaphu elesibini kuphela kwilaphu lenayiloni elakhiwe ngespunbond elingalukwanga. Amandla ayo agqwesileyo, ukungena komoya okulungileyo, ukuxhathisa, ukuxhathisa ukukrazula kunye neempawu zokuchasana nokuguga ziye zasetyenziswa kwiinkalo ezahlukeneyo ngabantu abaninzi.

Ilaphu lePET spunbond elingalukwanga likwanepropathi ebonakalayo ekhethekileyo: ukuxhathisa kwimitha ye-gamma. Oko kukuthi, ukuba isetyenziswe kwiimveliso zonyango, imitha ye-gamma ingasetyenziselwa ukubulawa kweentsholongwane ngaphandle kokonakalisa iipropati zabo zomzimba kunye nokuzinza kwe-dimensional, okuyipropati ebonakalayo i-polypropylene (PP) i-spunbond engalukiweyo ayinayo.

Ilaphu le-polypropylene elingalukwanga

Ilaphu eliphothiweyo elingalukwanga libhekiselele kwintambo eqhubekayo eyenziwe yi-extrusion kunye nokwelulwa kweepolymers, ezibekwe kwiwebhu. I-web iyazibophelela, idityaniswe ngokushushu, idityaniswe ngokwekhemikhali okanye iqiniswe ngoomatshini ukuze ijike iwebhu ibe lilaphu elingalukwanga. Isetyenziselwa iimveliso zococeko ezilahlwayo, ezinje ngeenapkins zococeko, iigawuni zotyando, iminqwazi, iimaski, iibhedi, amalaphu e-diaper, njl njl.

Ipolypropylene engalukwanga vs ipolyester

I-PP yimathiriyeli ekrwada yepolypropylene, oko kukuthi i-polypropylene fiber, eyelaphu elibhityileyo elingalukwanga; I-PET yinto entsha kraca yepolyester ekrwada, eyifiber yepolyester, engenazo zongezo kuyo yonke inkqubo yemveliso. Yimveliso encomekayo kakhulu ehambelana nokusingqongileyo kwaye yeyelaphu elishinyeneyo elingalukwanga.

Umahluko phakathi kwe-polypropylene kunye ne-polyester fibers

1, Umgaqo wokuvelisa

Imigaqo yokuvelisa i-polypropylene kunye ne-polyester fibers iyahluka. I-Polypropylene ilungiswa ngokufudumeza i-propylene monomers kubushushu obuphezulu kwaye yongeze kwi-catalyst ye-polymerization, ngelixa iifayili ze-polyester zicutshungulwa zibe yizinto zefiber ngokudibanisa i-cellulose etherification agents kunye ne-solvents kwi-polyester resin.

2. Iimpawu zePropati

1. Ngokweempawu zomzimba:

I-Polypropylene ilula kakhulu kwaye inamandla aphezulu efayibha, kodwa ukuxhathisa ukunxitywa kunye nokumelana nobushushu obuphezulu akubikho. Iintsinga zePolyester zinamandla aphezulu kunye nokuqina, kunye nobushushu kunye nokumelana neekhemikhali, okukhokelela kubomi obude benkonzo.

2. Ngokweempawu zekhemikhali:

I-Polypropylene ineempawu zeekhemikhali ezizinzile, akulula ukugqweswa yi-acids, i-alkalis, njl., kwaye ayinayo izinto ezinobuthi neziyingozi. Ifiber yepolyester inesakhiwo seringi yebenzene kwaye inomlinganiselo othile wokumelana nokutyiwa.

3. Ngokuhambelana nokusingqongileyo:

I-Polypropylene yimathiriyeli ye-thermoplastic engaguquki lula kwaye ingcolise indalo. Iintsinga zePolyester zingonakaliswa ziimicroorganisms kwaye aziyi kubangela ukungcoliseka kwendalo.

Umahluko phakathi kwe-PP engalukiweyo ilaphu kunyeIlaphu elingalukwanga le-PET

1. Iimathiriyeli ekrwada zePP zitshiphu, ngelixa imathiriyeli ekrwada yePET zibiza kakhulu. Inkunkuma yePP inokuphinda isetyenziswe kwiziko, ngelixa inkunkuma ye-PET ayinakuphinda isetyenziswe, ngoko ke iindleko zePP zingaphantsi kancinci.

2. I-PP inokumelana nobushushu obuphezulu malunga nama-degrees angama-200, ngelixa i-PET inokumelana nokushisa malunga ne-290 degrees. I-PET ixhathisa kakhulu kubushushu obuphezulu kune-PP.

3. Ukuprintwa kwelaphu elingalukwanga, isiphumo sokudlulisa ubushushu, ububanzi obufanayo be-PP buyancipha ngakumbi, i-PET iyancipha kancinci, inesiphumo esingcono, i-PET igcina ngakumbi kwaye ichithe kancinci.

4. Amandla okuqina, ukunyanzeliswa, amandla okuthwala umthwalo, kunye nobunzima obufanayo, i-PET inamandla amakhulu, i-tension, kunye nomthwalo wokuthwala umthwalo kunePP. I-65 grams ye-PET ilingana ne-80 grams ye-PP ngokwemiqathango yoxinzelelo, ukuxhatshazwa, kunye nomthwalo wokuthwala umthwalo.

5. Ukusuka kumbono wokusingqongileyo, i-PP ixutywe nenkunkuma yePP esetyenzisiweyo, kwaye zonke ii-PET chips zintsha kraca. I-PET ihambelana nokusingqongileyo kwaye icocekile kune-PP.
