Emva kweminyaka yokuziqhelanisa nemveliso, inkampani yethu, i-Highsun Synthetic Fiber Technologies Co., Ltd., ngokuthe ngcembe yafumanisa impembelelo yobushushu bebhokisi eshushu kwi-crimping, amandla kunye nokudaya inayiloni 6.
1. Impembelelo kwi-nayiloni 6 ye-crimping
Ngaphantsi kweemeko zokuvelisa umlinganiselo wokwelula amaxesha angama-1.239, i-D / Y ye-2.10 kunye nesantya se-700m / min, i-crimp shrinkage kunye ne-crimp stability yanda ngokunyuka kweqondo lokushisa kwinqanaba elithile.Oku kungenxa yokuba iplastiki yefiber iphuculwa ngokunyuka kwamaqondo obushushu, okwenza kube lula ukonakala.Ke inayiloni yesi-6 ithambile kwaye ikhubazeke ngokupheleleyo.Nangona kunjalo, xa iqondo lobushushu lisezantsi kakhulu (ngaphantsi kwe-182℃), ireyithi yecrimp kunye nozinzo lwecrimp ye-nayiloni 6 imathiriyeli iyancipha nayo.Umcu uthambile kwaye unelastic, obizwa ngokuba yisilika yomqhaphu.Xa iqondo lobushushu liphezulu kakhulu (ngaphezu kwe-196℃), umcu ocudiweyo uyaqina kwaye uqine.Oku kungenxa yokuba iintsinga ziye zibe brittle phantsi kobushushu obuphezulu, nto leyo ekhokelela kwiifibrils ezidityaniswayo zibe yimicu eqinile.Ngoko ke, i-crimp shrinkage iyancipha kakhulu.
2. Impembelelo kwinayiloni 6 amandla
Ngexesha lenkqubo yokuvelisa, kwafunyaniswa ukuba ubushushu bebhokisi eshushu nayo yaba nefuthe elikhulu kumandla enayiloni 6. Phantsi kweemeko zobuchwepheshe zokulayisha isantya 630m/min, umlinganiselo wokolula amaxesha angama-1.24 kunye ne-D/Y 2.03, ukunyanzeliswa kokujija kuyancipha. kunye noxinzelelo olungajikiyo nalo luyehla ngokunyuka kwamaqondo obushushu, okubangwa kukuthamba kwefiber kwiqondo lobushushu eliphezulu.Kwiqondo lobushushu elisezantsi noko, amandla ayanda ngokunyuka kwamaqondo obushushu, kodwa ayancipha ngokunyuka kwamaqondo obushushu (193℃).Oku kungenxa yokuba kwiqondo lobushushu eliphantsi ngokwentelekiso, isakhono somsebenzi weemolekyuli zefayibha zanda ngokunyuka kwamaqondo obushushu, nto leyo enciphisa uxinzelelo lwangaphakathi kwinkqubo yokuguqulwa kwe-thermal, yenza kube lula ukukhubaza kunye nokwandisa amandla e-filament.Nangona kunjalo, ngokunyuka okungaphezulu kweqondo lokushisa, ukuqhelaniswa kwe-amorphous kwifiber kulula uku-de-oriented.Xa ubushushu bufikelela kwi-196℃, iintsinga eziveliswayo ziye ziqine kwaye ziqine kwaye zibonakale zimbi kakhulu.Emva kovavanyo oluninzi, kwafunyaniswa ukuba inayiloni yesi-6 yayinamandla aphezulu xa ubushushu bebhokisi eshushu yayiyi-187℃.Ewe, oku kufuneka kuhlengahlengiswe ngokwesantya esiphezulu sokulayisha sePOY yenayiloni.Ngokutsho kwamava, ukungcola kweoli kunye nothuli luya kunamathela kwibhokisi eshushu kunye nokunciphisa ukucoceka komatshini, okuya kunciphisa ukusebenza kakuhle kokufudumeza.
3. Impembelelo yokudaya enayiloni 6
Xa iqondo lobushushu kwibhokisi eshushu lisezantsi, inayiloni 6 inecrystallinity esezantsi, intambo eyomeleleyo yokudaya, kunye nobunzulu bokudaya obuphezulu.Ngokuchasene noko, ubushushu obuphezulu bebhokisi eshushu bubangela ukudaya okukhanyayo kunye nokuthathwa kwedayi ephantsi ye-nylon 6. Ngenxa yokuba iqondo lokushisa elibonisiweyo lomatshini ngamanye amaxesha liyaphambuka kakhulu kwiqondo lokushisa elilinganisiweyo, xa iqondo lokushisa lihlengahlengiswa ukuya kuma-210 ° C kwimveliso yangempela, imbonakalo kunye nezalathisi zomzimba zenayiloni 6 zilungile, kodwa isiphumo sombala sibi.
