Mukushandiswa kwepolypropylene fiber spinning, kushanda kwepolyethylene wax kunogumira. Kune akajairwa dhinier sirika yemhando yepamusoro uye shinda dzemhando yepamusoro, kunyanya kune mvere dzakapfava senge faini denier uye BCF filaments inokodzera pave uye zvipfeko zvemachira, polypropylene wakisi inowanzodiwa pane polyethylene wakisi.

Chokutanga pane zvose, nekuda kwekusawirirana pakati pepolypropylene uye polyethylene, zvakaoma zvikuru kuumba yunifomu kusanganiswa mupfungwa ye microscopic, iyo inotungamirira pakuparadzaniswa kwechikamu. Chechipiri, nekuti kunyunguduka polyethylene namo yakadzikira zvakanyanya pane yepolypropylene kana polypropylene wax, zvinonetsa kubata nekunyunguduka kwakasiyana kwemapolymer maviri aya. Izvo zvisina kuenzana uye zvisina kukodzera rheology yechigadzirwa inogona kutungamirira kumagumo ekuputsa kwekutenderera. Nekuda kweiyi mhedzisiro, iwo emuviri machira emhando yefiber anowedzera kuipa.
Panguva ino, zvakakosha kushandisa polypropylene wax ine low viscosity. Nekuda kwekushomeka kwayo uye kunyorova kwakanaka, inogona kunyorovesa pigment munguva pfupi. Pamusoro pezvo, kana polypropylene faibha yakatambanudzwa uye inopisa, inogona kuwanikwa kubva pakupisa kupisa tembiricha (kazhinji ingangoita 130c), iri mukati mekunyunguduka kwekushisa kwe polyethylene wax.

Nekuda kwekuchinja kwekristalline chimiro chepolypropylene primary fiber, zvinogona kucherechedzwa kuti yakanyungudutswa polyethylene wakisi inopinda kubva papolypropylene matrix kusvika kune fiber pamusoro, uye haisi chete wakisi yakachena, asiwo pigment ichaunzwa pamusoro.
Chekupedzisira, kugarisana pakati pepolypropylene wax nepolypropylene resin yakanaka mune zvese zvidiki uye macro aspects, uye haina mhedzisiro pamichina. Kune marudzi maviri epolypropylene wakisi yakapolymerized nemetallocene catalytic technology: imwe ihomopolymer polypropylene wax, uye mbishi ipropylene; Imwe yacho icopolymerized polypropylene wax, iyo yakagadzirwa nepropylene uye ethylene.
Kazhinji, homopolymer polypropylene wax ine yakakwira kunyungudika, pakati pe140-160c, huremu hwemamorekuru kubva kuzviuru kusvika kumakumi ezviuru, inoenderana Brookfield viscosity kubva kumakumi kusvika kuzviuru, yakakwirira crystallinity uye kuoma kwakanyanya. Nzvimbo yekunyunguduka kwecopolymer polypropylene wax inowanzova pakati pe80-110c, viscosity yeBrookfield mazana kusvika kuzviuru kana kunyange makumi ezviuru, uye huremu hwemamorekuru hunoenderana nezviuru kusvika makumi ezviuru. Pamusana pekuwedzera kwe ethylene comonomer mu polypropylene copolymer, iyo inokanganisa kurongeka kwemaitiro epropylene molecules, crystallinity ye polypropylene copolymer yakaderera, saka nzvimbo yekunyunguduka yakaderera zvakare.

Muchikamu chekunyorova kwe pigment, kunyorova kwakaderera kwewakisi kunoitika nekukurumidza, uye kugona kwekunyorova kwakakwira. Asi inodiwa muwaya extrusion. Muchikamu chegranulation, tinovimba zvakare kuti wakisi ine imwe viscosity, iyo inogona kufambisa simba rekugera pakati pe pigment neresin inonyunguduka, kuitira kuti pigment yakanyoroveswa igovaniswe zvakaenzana mu resin inonyungudika. Panguva ino, wakisi yepolypropylene ine yakaderera kunyungudika uye polypropylene wakisi ine high viscosity inogona kushandiswa pamwechete kuti iwane kupararira kwakanyanya.
