I-Biobased PA56 ilungiswa ukusuka kwimithombo ehlaziyiweyo efana nombona kunye nengqolowa ngendlela ye-microbial kwaye emva koko i-polymerized nge-adipic acid. Iimpawu zayo zifana nezo ze-PA6 kunye ne-PA66, kwaye ingasetyenziselwa kwi-textile, iiplastiki zobunjineli kunye nezinye iindawo.Ngokwempembelelo yokusingqongileyo, inokutshintsha ezinye iimveliso zefiber ze-polyamide ezisekelwe kwi-petroleum.

Iimpawu ezibonakalayo ze

Ubuninzi bebhayoloji PA56 ngokuqhelekileyo yi-1.12 ~ 1.14 g/cm3, eneempawu ezilungileyo zoomatshini. Izibophelelo ze-Hydrogen zinokuqulunqwa phakathi kwamacandelo e-fiber ye-chain, kwaye amandla okuphuka afana ne-PA6.Xa ukuqulunqwa kwe-multiple of biobased PA56 filament kunye ne-viscosities eyahlukeneyo yi-3 ~ 3.5, amandla okuphuka kunye ne-modulus yokuqala yonyuka ngokuyila. ukwanda okuphindaphindiweyo.Kukho iqela le-hydrophilic amide kwifiber, enika ifayibha i-hygroscopicity ethile, akukho lula ukuvelisa umbane osisigxina, kwaye ine-soft feel.Isantya sokufunxa samanzi e-bio-based PA56 yi-14%, iphezulu kune-PA6 kunye ne-PA66 , ngoko ke inentuthuzelo engcono ekunxibeni nasekunxibeni.

Ukusebenza kokudaya

I-Biobased PA56 fibers inokudaywa ngedayi ye-asidi ebuthathaka, idayi esebenzayo kwaye isasaze idayi ene-polarity enamandla.Kwisakhiwo sayo semolekyuli, inani leathom zekhabhoni kumacandelo amakhonkco aphambili afana ne-PA6, PA66, imbalwa kodwa ngaphezulu kwe-PA66 diamine ene-athomu yekhabhoni enye. , yenza ekuqaleni inokuvelisa i-hydrogen bond kwiindawo ze-PA66 yimeko yamahhala ye-hydrogen kunye ne-oksijini, ngaloo ndlela inyusa i-PA56 yokudaya locus, kunye nokongezwa kwe-carbonyl amino yefiber kunye nokufunxa kwamanzi, kunye nokufuduka kwangaphakathi, ukwenza i-PA56 ukudaya kunye nokuthamba.

Ukuthatha ukusebenza

I-Bio-based PA56 fiber ineempawu ezibalaseleyo zomzimba kunye neekhemikhali, kwaye inethemba elibanzi lesicelo kwintsimi yokusetyenziswa ngenxa yokuthamba kwayo, i-anti-pilling, ukufunxa ukufuma kunye ne-flame retardant.Isakhiwo se-asymmetric phakathi kwee-molecule zenza i-PA56 ifane nokuthamba kwiwulu. ngaphandle kokuchaphazela amandla ayo kunye nokuxhatshazwa kokugqoka.

Imeko yesicelo

I-Bio-based PA56 fibers okwangoku ibandakanya i-filament, i-staple kunye ne-composite fibers, phakathi kwayo i-filament ibandakanya i-filament e-pre-oriented (POY), i-stretch textured filament (DTY) kunye nefilament eyolulwe ngokupheleleyo (fdy).I-Bio - i-PA56 i-staple yarns inoboya obuncinci kwaye igudile kwaye ithambile ukuluka.Iimpawu ezisisiseko ze-PA56 ziyafana nezo ze-polyamide zemveli, kwaye zinokudibaniswa noboya, i-cellulose fiber (i-cotton, i-viscose fiber, i-tiansi TM) ifayibha yepolyacrylonitrile, ifayibha yeacetate, Polyester ifayibha, njl., enethuba elithile lesicelo kwintsimi yokusetyenziswa.I-PA56 inokuthamba okulungileyo kwaye inokunyusa amandla omsonto xa idityaniswe noboya.

Ukongeza, i-PA56 esekwe kwi-bio inokuphinda isetyenziswe njengezinto ezisetyenziswayo kwizinto ezilukiweyo zemizi-mveliso, ilaphu lomkhosi, iiplastiki zobunjineli, iifilimu zokupakisha ukutya, njl. njl.PA56 inokwenziwa ibe ngumsonto owandisiweyo ngamandla angcono kunye ne-hygroscopicity kune-PA6 kunye ne-PA66, inqanaba eliphezulu le-PA6. i-pomeness kunye ne-flame retardant engcono kune-PA66 kunye ne-PAXNUMX, engasetyenziselwa ukuluka iikhaphethi. njl.Kwimpahla yomkhosi, ingasetyenziselwa ukusetyenzwa kweparashute, intente, ibhegi yokulala, njl.

Ngolwazi oluthe kratya, nceda uqaphele "ukusebenza kunye nokusetyenziswa kwe-bio-based chemical fiber PA56", i-2019 inqaku lesi-8, isikhokelo se-textile.
