Raws li cov ntaub ntawv tseem ceeb hauv kev paj ntaub niaj hnub, polyester paj ntaub xov ua haujlwm los ntawm kev sib koom ua ke ntawm cov ntaub ntawv science, textile technology, thiab mechanical engineering. Los ntawm nws cov khoom tshwj xeeb physicochemical thiab cov cuab yeej ua tiav, polyester paj ntaub xov ua tiav cov stitching meej, ruaj khov shaping, thiab durability nyob rau hauv siab - cov khoom siv paj ntaub ceev, ua rau nws cov khoom tseem ceeb hauv khaub ncaws, kho kom zoo nkauj hauv tsev, thiab kos npe rau kev lag luam.
Los ntawm cov ntaub ntawv muaj pes tsawg leeg, polyester paj ntaub xov siv polyester fiber (PET) raws li nws cov ntaub ntawv tseem ceeb, ua los ntawm yaj spinning los ua ib tug siab - zog thiab tawv monofilament los yog multifilament qauv. Cov ester bonds nyob rau hauv nws cov saw molecular endow lub fiber nrog zoo heev tensile zog thiab puas kuj, thaum nws nruj molecular kev npaj muab nws tsis tshua muaj noo noo nqus (qhib noo noo tsuas yog 0.4%), tswj qhov seem stability txawm nyob rau hauv ib puag ncig ntub thiab tiv thaiv xov expansion los yog contraction vim ya raws. Tsis tas li ntawd, qhov chaw du thiab qis coefficient ntawm kev sib txhuam ntawm polyester fibers txo qhov kev tiv thaiv ntawm cov paj ntaub tshuab koob thiab cov xov, ua kom cov stitching du yam tsis muaj kev pheej hmoo ntawm kev tawg thaum lub sijhawm ua haujlwm siab -.
Hauv kev paj ntaub, kev ua haujlwm ntawm polyester paj ntaub xov tuaj yeem muab faib ua peb theem tseem ceeb: noj, tswj nruj, thiab kho pob. Ua ntej, cov xov polyester ntawm lub spool yog pub ntawm ib qho kev sib tw ceev mus rau rab koob ntawm lub tshuab paj ntaub los ntawm kev qhia cov menyuam. Nws cov xov tsis sib xws (feem ntau yog 50-600 denier) kom paub meej qhov puv ntawm cov stitches. Thib ob, lub tshuab ua tau - nyob rau hauv qhov nro hloov cuab yeej dynamically kho cov xov nro ntawm lub caij nplooj ntoos hlav los yog sib nqus system-thaum lub koob nkag mus rau hauv cov ntaub, lub instantaneous nro ntawm cov xov yog compensated rau thiab tso tawm, tiv thaiv breakage vim muaj zog heev. Thaum kawg, thaum lub koob rov qab stroke, xov loops intertwine nrog bobbin xov los tsim ib lub lockstitch. Lub siab melting point ntawm polyester fiber (kwv yees li 250-260 degree) tso cai rau ntxiv solidification ntawm stitch qauv los ntawm qhov chaw sov, txhim khu tag nrho cov durability.
Nws yog ib qho tsim nyog sau cia tias cov xim nthuav tawm ntawm polyester paj ntaub xov kuj yog los ntawm nws cov tshuaj ruaj khov. Los ntawm cov tshuaj dyeing los yog siab - kub, siab - cov txheej txheem dyeing siab, dye molecules tuaj yeem nkag mus rau hauv fiber ntau sab hauv, ua rau lub teeb ci thiab ntxuav ceev (txog qib 4-5), tswj cov xim vibrant txawm tias tom qab lub teeb raug ultraviolet ntev los yog nquag ntxuav.
Hauv cov ntsiab lus, polyester paj ntaub xov, los ntawm kev sib xyaw ntawm cov khoom siv thiab cov txheej txheem ua kom zoo, ua tiav qhov sib npaug ntawm cov neeg kho tshuab kev ntxhov siab, kev hloov pauv ib puag ncig, thiab kev xav zoo nkauj. Nws txoj haujlwm ua haujlwm tau zoo thiab ruaj khov tsis yog tsuas yog txhawb nqa kev lag luam ntawm cov paj ntaub tshuab, tab sis kuj muab lub hauv paus txhim khu kev qha rau kev tsim cov khoom siv textiles.
