Polyester yarn hais txog cov xov paj spun los ntawm polyester li raw khoom. Polyester yog ib hom fiber ntau ua los ntawm spinning ib hom polymer, feem ntau yog hais txog cov fiber ntau uas ua los ntawm ethylene phthalate li raw khoom. Lub npe "polyethylene terephthalate" luv luv, hu ua "PET" fiber. Feem ntau hu ua polyester hauv peb lub teb chaws. Lub npe hu ua "yarn" tiag tiag yog hais txog lub ntsiab lus ntawm "yarn" thiab "xov", uas yog txhais raws li hauv qab no hauv cov ntaub ntawv kev tshawb fawb: "yarn" yog kev npaj ntawm ntau cov fibers luv lossis filaments nyob rau hauv ib qho kev kwv yees li ntawm lub xeev, thiab raws li cov kev taw qhia axial Tig thiab twist los ua ib qho khoom sib luag nrog qee lub zog thiab linear ceev; thiab "xov" yog ib qho strand tsim los ntawm twisting ob los yog ntau tshaj ib yarns. Cov xov paj yog ib txoj hlua nyias ntawm paj rwb, ntaub plaub, hemp, tshuaj fiber ntau, thiab lwm yam, uas yog elongated thiab twisted (feem ntau yog siv los ua raw khoom rau kev xaws), thiab ces ua los ntawm paj rwb, hemp, txhob lo lo ntxhuav, ntaub plaub thiab lwm yam zoo strands. Nyias strands, hu ua threads.
Polyester fiber yog hais txog cov saw tseem ceeb uas muaj ester pawg, ib hom polymer fiber ntau ua los ntawm spinning, feem ntau yog hais txog cov fiber ntau uas ua los ntawm ethylene phthalate raws li cov khoom siv raw, raws li lus Askiv lub npe ntawm nws cov khoom siv raw "polyethylene terephthalate" Abbreviation, xa mus rau Raws li "PET" fiber ntau. Feem ntau hu ua polyester hauv peb lub teb chaws. Lub npe hu ua "yarn" tiag tiag yog hais txog lub ntsiab lus ntawm "yarn" thiab "xov", uas yog txhais raws li hauv qab no hauv cov ntaub ntawv kev tshawb fawb: "yarn" yog kev npaj ntawm ntau cov fibers luv lossis filaments nyob rau hauv ib qho kev kwv yees li ntawm lub xeev, thiab raws li cov kev taw qhia axial Tig thiab twist los ua ib qho khoom sib luag nrog qee lub zog thiab linear ceev; thiab "xov" yog ib qho strand tsim los ntawm twisting ob los yog ntau tshaj ib yarns.
Fiber muaj ob yam tseem ceeb: ib qho yog tias nws nyias nyias uas tib neeg tsis tuaj yeem saib ncaj qha rau ntawm qhov muag liab qab, thiab txoj kab uas hla feem ntau yog nruab nrab ntawm ob peb microns mus rau kaum ntawm microns lossis finer; Lub infinity muaj feem xyuam rau hom fiber ntau, uas ua rau cov fiber ntau mechanically nthuav cov khoom ntev, xws li ib feem me me ntawm ib nrab deformation thaum nws yog khoov thiab twisted, thiab deformation ntau heev txawm nyob rau hauv lub elastic ntau yam thaum nws stretched tag nrho. . Yog li ntawd, hais lus yooj yim, cov fiber ntau yog ib hom nyias thiab ntev, uas yog, txoj kab uas hla yog me me uas nws tsis tuaj yeem pom ncaj qha los ntawm qhov muag liab qab, thiab qhov sib piv ntawm nws qhov ntev rau nws txoj kab uas hla yog ntau tshaj kaum tawm zaus.
