Ekusetyenzisweni kwe-polypropylene fiber spinning, ukusetyenziswa kwe-wax ye-polyethylene kulinganiselwe. Kwisilika eqhelekileyo yedenier ecolekileyo kunye neentsinga ezikumgangatho ophezulu, ngakumbi kuboya obuthambileyo obufana ne-denier ecikizekileyo kunye neentsinga ze-BCF ezifanelekileyo kwipaveying kunye neempahla ezilukiweyo, i wax ye-polypropylene ukukhetha kunewax ye-polyethylene.

Okokuqala, ngenxa yokungahambelani phakathi kwe-polypropylene kunye ne-polyethylene, kunzima kakhulu ukwenza ukuxuba okufanayo kwingqiqo ye-microscopic, eya kubangela ukuhlukana kwesigaba. Okwesibini, ngenxa yokuba indawo yokunyibilika ye- polyethylene amafutha iphantsi kakhulu kune-polypropylene okanye i-polypropylene wax, kunzima ukujongana neempawu zokunyibilika kwezi zimbini zeepolymers. Ukungalingani kunye ne-rheology engafanelekanga yemveliso kunokukhokelela ekuqhekekeni kokuphela kwenkqubo yokujikeleza. Ngenxa yezi ziphumo ebezingalindelekanga, iipropathi ze-textile ezilukiweyo zefiber ziba mandundu.
Ngeli xesha, kuyimfuneko ukusebenzisa i-polypropylene wax kunye ne-viscosity ephantsi. Ngenxa ye-viscosity yayo ephantsi kunye nokumanzisa kakuhle, inokumanzisa ii-pigments ngexesha elifutshane. Ukongeza, xa ifayibha ye-polypropylene isoluliwe kwaye isetyenzisiwe ubushushu, inokufumaneka kwiqondo lokushisa lobushushu (lidla ngokuba malunga ne-130c), elingaphakathi nje kuluhlu lobushushu obunyibilikayo lwe-polyethylene wax.

Ngenxa yotshintsho lwesakhiwo sekristale se-polypropylene ifayibha yokuqala, kunokubonwa ukuba i-polyethylene wax etyhidiweyo iphuma kwi-polypropylene matrix ukuya kumphezulu wefiber, kwaye ayiyona nje i-wax ecocekileyo, kodwa kunye ne-pigment iya kuziswa phezulu.
Ekugqibeleni, ukuhambelana phakathi kwe-polypropylene wax kunye ne-polypropylene resin ilungile kuzo zombini iinkalo ezincinci kunye ne-macro, kwaye inefuthe elincinci kwiipropati zoomatshini. Kukho iindidi ezimbini ze-polypropylene wax eyenziwe nge-metallocene catalytic technology: enye yi-homopolymer polypropylene wax, kunye nempahla eluhlaza yipropylene; Enye yi-copolymerized polypropylene wax, eyenziwe ngepropylene kunye ne-ethylene.
Ngokubanzi, i-homopolymer polypropylene wax inendawo yokunyibilika ephezulu, phakathi kwe-140-160c, ubunzima bemolekyuli ukusuka kumawaka ukuya kumashumi amawaka, ehambelana ne-Brookfield viscosity ukusuka kumashumi ukuya kumawaka, ubucwebe obuphezulu kunye nobunzima obuphezulu. Indawo yokunyibilika ye-copolymer polypropylene wax idla ngokuba phakathi kwe80-110c, i-viscosity yaseBrookfield ngamakhulu ukuya kumawaka okanye amashumi amawaka, kwaye ubunzima bemolekyuli obuhambelana namawaka ukuya kumashumi amawaka. Ngenxa yokongezwa kwe-ethylene comonomer kwi-polypropylene copolymer, ephazamisa ukucwangciswa rhoqo kweemolekyuli zepropylene, i-crystallinity ye-polypropylene copolymer iphantsi, ngoko ke indawo yokunyibilika nayo iphantsi.

Kwinqanaba lokumanzisa i-pigment, ukumanzisa kwe-viscosity ephantsi kwenzeka ngokukhawuleza, kwaye ukusebenza kakuhle kokumanzisa kuphezulu. Kodwa iyafuneka kwi-extrusion yocingo. Kwinqanaba le-granulation, sinethemba lokuba i-wax ine-viscosity ethile, enokuthi idlulise kakuhle i-shear force phakathi kwe-pigment kunye ne-resin enyibilikayo, ukuze i-pigment emanzi ihanjiswe ngokulinganayo kwi-resin melt. Ngeli xesha, i-wax ye-polypropylene enendawo ephantsi yokunyibilika kunye ne-polypropylene wax ene-viscosity ephezulu ingasetyenziselwa kunye ukufezekisa ukusabalalisa okulungileyo.
