Kev tsim tawm ntawmPP Non Woven Khw Hnab muab faib ua ob theem. Ua ntej, lub dav hlau hlau melts polypropylene hais thiab thawb cov khoom molten rau hauv spinneret los tsim cov fibers tas li. Cov fibers tau stretched rau hauv ib lub web. Rhaub cov menyuam compacts lub web ntawv los ua ntaub.
Lub hnab ntau lawm kab Tom ntej no txiav cov ntaub thiab ua lub hnab thiab tuav los ntawm ultrasonic vuam los yog stitching. Nws kuj ntxiv ruffles thiab kev txhawb zog, ces luam tawm thiab ua tiav lub hnab. Qhov hnyav ntawm cov ntaub, daim ntawv cog lus qauv thiab weld zoo yog txiav txim siab nyob rau hauv thawj theem. tuav lub zog thiab luam ntawv txoj hauj lwm yog txiav txim nyob rau hauv lub thib ob theem.
Theem 1: Resin rau ntaub
Kev npaj melting
Txhua lub hnab pib nrog polypropylene pellets. Raws li ISO 1133-1, lub melt flow index feem ntau yog 25-1. Yog tias cov yaj yog kua heev, filaments yuav tawg thaum lub sij hawm ncab. Yog tias nws tuab heev, lub siab ntawm lub nozzle nce.
Muaj ob txoj hauv kev ntxiv xim. Thawj txoj kev yog niam-granule tswj. Nws sib tov 2-4% pigment ntawm cov concentrated pigment rau hauv yaj. Txoj kev no yog ceev thiab yoog raws, tab sis cov pigment kis thoob plaws hauv cov filament. Qhov thib ob txoj kev yog dope dyeing, uas yog, spinning resin. Nws pigments lub polymer ua ntej extruding. Yog li ntawd, cov xim yuav zoo ib yam nyob rau lub sij hawm ntev ntau lawm. Nws kuj tseem pab xim kom ntev dua thaum ntxuav thiab raug UV rays, vim cov xim nyob hauv cov fiber ntau. Qhov kev xaiv no cuam tshuam rau ISO 105-X12 rubbing qib ntawm lub hnab tiav.
Reabrasion los ntawm ntug trim feem ntau yog pub rov qab rau hauv txoj kab hauv ib qho kev faib ua feem. Qhov no pab txo cov khoom pov tseg hauv kev tsim cov khoom tsis yog -woven fabrics. Cov neeg muag khoom yuav tsum hais qhov tseeb qhov sib piv, tsis yog hu nws "recycling."
Filament extrusion thiab stretch
Cov yaj yog lim thiab ntsuas, ces thawb los ntawm lub nozzle nrog ntau txhiab qhov me me. Cov filaments tuaj tawm kom txias nrog cua tsis tu ncua. Tom qab ntawd, siab- cua nrawm nrawm ntawm cov fiber ntau txo nws txoj kab uas hla mus rau 1.5–3.0 dtex, uas yog ib txwm muaj hauv hnab ntaub.
Stretching yog ib kauj ruam tseem ceeb hauv cov txheej txheem no. Nws npaj cov saw hlau polymer raws qhov ntev ntawm txhua qhov filament. Qhov no muab cov fiber ntau lawv lub zog tensile. Lub hnab muaj zog vim tias cov fibers tau ncab, tsis yog vim cov ntaub tuab heev. Qhov hnyav thiab lub zog ntawm cov ntaub, tab sis lawv txawv. Ob 80 gsm fabrics muaj qhov sib txawv tawg rog yog tias ncab ntau txoj hauv kev.
