Kev npaj microfiber

Cov pa microfibers feem ntau muab faib ua ob hom: filament thiab luv filament.Ntau hom fiber ntau muaj cov ntawv sib txawv.Cov ntaub ntawv spinning ntawm cov pa ultrafine fiber ntau filaments feem ntau suav nrog kev sib tw ncaj qha thiab sib xyaw spinning.Cov ntaub ntawv spinning ntawm cov pa ultrafine fiber luv luv filaments feem ntau suav nrog cov qauv fiber ntau alkali txo txoj kev, dav hlau spinning txoj kev, thiab muab cov txheej txheem spinning.tos.
1. Direct spinning method Qhov no yog ib txoj kev siv tshuab spinning uas siv cov txheej txheem melting ib txwm siv los npaj cov fibers ultrafine siv cov khoom siv raw (polyester, nylon, polypropylene, thiab lwm yam).Cov txheej txheem yog yooj yim thiab yooj yim rau kev khiav lag luam, tab sis nws yog ib qho yooj yim los npaj cov fiber ntau.Qhov kawg tshwm sim thiab cov qhov spinneret tau yooj yim thaiv.
2. Composite spinning method Txoj kev no siv cov tshuab sib xyaw spinning los tsim cov fibers sib xyaw, thiab tom qab ntawd siv cov txheej txheem kev kho lub cev lossis tshuaj los cais cov fibers sib xyaw ua ntau theem, yog li tau txais cov fibers ultra-fine.Kev vam meej ntawm kev sib xyaw spinning thev naus laus zis cim cov fiber ntau zoo.Qhov pib tiag tiag ntawm kev txhim kho fiber ntau zoo.

3. Txoj kev txo qis alkali: Txoj kev no yog siv rau polyester fiber ntau, siv dilute alkali tov los kho polyester fiber kom ua tiav lub hom phiaj ntawm refining fiber.
4. Lub dav hlau spinning txoj kev no feem ntau yog siv polypropylene raws li cov khoom siv spinning, thiab txau cov viscosity tsawg-viscosity polymer yaj rau hauv cov fibers luv luv los ntawm lub dav hlau cua ntws.
5. Blended spinning method Qhov no yog kom yaj thiab muab ob lossis ntau dua cov ntaub ntawv polymer rau spinning.Vim qhov sib txawv ntawm cov yam ntxwv ntawm lub cev xws li cov ntsiab lus thiab viscosity ntawm cov khoom sib txawv, cov kuab tshuaj tuaj yeem siv los ua kom tiav lub hom phiaj ntawm spinning.Kev sib cais kom tau txais cov fibers luv luv tsis txuas ntxiv.
