Cov txheej txheem tsim khoom ntawm FIBCs yog qhov nyuaj, xav tau ntau cov kauj ruam, txhua qhov cuam tshuam ncaj qha rau qhov zoo ntawm cov khoom kawg.
Cov txheej txheem npaj cov khoom siv raw feem ntau yog siv polypropylene lossis polyethylene resin ua cov khoom siv tseem ceeb, nrog rau cov khoom siv me me ntxiv thiab sib xyaw ua ke.
Cov ntaub ntawv yas raw khoom no yog pub rau hauv extruder rau yaj extrusion los ua ib zaj duab xis yas. Cov yeeb yaj kiab no yog tom qab ntawd txiav rau hauv filaments, ncab ntawm qhov kub hauv qab ntawm cov resin melting point, thiab ua rau siab -lub zog, qis- elongation ca yarns los ntawm molecular orientation thiab cua sov.
Cov txheej txheem weaving tom ntej no suav nrog warping, weaving, thiab laminating lub tiaj yarns los tsim cov ntaub yas woven raws li lub hauv paus ntaub. Qhov zoo ntawm lub hauv paus ntaub ncaj qha txiav txim siab load-cov kabmob muaj peev xwm thiab kav ntev ntawm FIBC. Feem ntau, lub zog tensile ntawm lub hauv paus ntaub yuav tsum ua kom tau raws li cov qauv, xws li lub zog tensile ntev dua 1470 N / 5 cm (rau FIBCs nrog lub peev xwm thauj khoom tsawg dua 1 tuj).
Kev tsim cov hlua khi yog qhov tseem ceeb sib npaug, xav tau cov txheej txheem xws li kev sib xyaw, kos duab, thiab xaws. Nyob rau hauv xyoo tas los no, ib hom sling ua los ntawm cov xov paj sib cais tau siv ntau zuj zus vim nws qhov hnyav, siab tensile zog, thiab kev zoo nkauj.
Cov kauj ruam kawg yog xaws, qhov twg lub hauv paus ntaub yog sewn rau lub slings thiab webbing los tsim ib tug saj zawg zog ntim hnab. Kev xaws yuav tsum ncaj, tsis muaj xoob stitches, tawg threads, los yog floating threads. Yuav tsum tsis txhob xoob stitches los yog overstitches, thiab txhua lub stitch yuav tsum tau backstitched tsawg kawg yog peb zaug los xyuas kom meej seam zog.
