Cov txheej txheem tsim khoom ntawm PP woven hnab feem ntau suav nrog cov kauj ruam tseem ceeb hauv qab no. Thawj kauj ruam yog kos duab filament. Polypropylene granules yog ntxiv rau lub extruder thiab rhuab ntawm qhov kub thiab txias kom yaj thiab plasticize lawv. Tom qab ntawd, lawv yog extruded los ntawm ib tug tuag rau hauv filaments, uas yog ces txias thiab stretched los txhim kho lawv lub zog thiab toughness. Cov filaments no yog cov khoom siv tseem ceeb ntawm lub hnab woven.
Qhov thib ob theem yog weaving. Tom qab kos duab filament, cov filaments yog pub rau lub tshuab xaws rau kev xaws. Lub tshuab weaving interweave cov filaments rau hauv cov ntaub siv ib txoj kev weaving tshwj xeeb. Lub weaving ceev thiab txoj kev cuam tshuam lub zog thiab durability ntawm lub hnab woven. Cov txheej txheem weaving feem ntau suav nrog kev sib tsoo yooj yim thiab kev tsis ncaj ncees, thiab cov txheej txheem sib txawv yog tsim rau cov txheej txheem sib txawv.
Kauj ruam peb yog luam ntawv. Raws li cov neeg siv khoom xav tau, cov ntaub woven yog luam tawm. Cov ntsiab lus luam tawm tuaj yeem yog lub tuam txhab logos, cov ntaub ntawv khoom, cov lus qhia siv, thiab lwm yam. Muaj ntau txoj kev luam ntawv, xws li gravure printing thiab flexographic printing, txhua tus muaj cov yam ntxwv sib txawv thiab kev siv.
Kauj ruam plaub yog txiav thiab xaws. Tom qab luam ntawv, cov ntaub yog txiav mus rau qhov tsim nyog loj thiab ces sewn. Qhov zoo ntawm kev xaws ncaj qha cuam tshuam rau lub sealing thiab durability ntawm lub hnab woven. Txoj kev xaws ib txwm muaj xws li tiaj stitching thiab overlock stitching; txoj kev xaws tsim nyog yuav tsum tau xaiv raws li qhov xav tau siv.
