Tan iyo bilowgii 2008, waxaan had iyo jeer diiradda on garoonka non-dhogorta. Ilaa maanta, waxaanu u adeegnay in ka badan 200 oo macaamiil ah gudaha iyo dibaddaba, waxaanan ku rakibnay in ka badan 600 khadadka wax soo saarka ee adduunka oo dhan.

Alaabooyinkayaga ugu muhiimsan waxaa ka mid ah: PP spunbond line-soo-saarka aan tolka lahayn, khad wax-soo-saarka dhalaalaysa, khad wax-soo-saarka aan-xidhka lahayn (sida SMS, SMMS, SSMMS, SMMMS ... iwm), Polyester (PET) khadka wax-soo-saarka aan tolka lahayn iwm. Si guul leh u daahfuray PLA/RPET khadka wax soo saarka dharka aan tolnayn ee 2021.

1. Waa maxay PET Nonwoven Fabric?
Polyester-ka (PET) ee loo yaqaan 'poliester filament' waa nooc ka mid ah maro aan tol lahayn, alaabteeda ceeriin waa 100% jeex polyester ah. Waxay ka samaysan tahay fiilo polyester ah oo badan oo joogto ah iyadoo la rogayo laguna xidho duuban kulul. Sidoo kale loo yaqaan PET spun viscose filament maro aan toleynin ama PES spun viscose maro aan-dhogorta lahayn, oo sidoo kale loo yaqaan hal qayb oo maro viscose ah oo aan tolnayn.

Astaamaha PET-ga dharka aan timaha lahayn

First, poliester (PET) spun viscose filament maro aan tol lahayn waa nooc ka mid ah maro aan tol lahayn oo biyaha celinaysa, marka loo eego cabbirka garaam ee kala duwan ee wax qabadka biyaha celinaya waa ka duwan yahay. Miisaanka garaamku wuu weyn yahay oo dhumucdiisuna way sii fiicnaanaysaa waxqabadka biyaha celinaya. Haddii ay jiraan dhibco biyo ah oo ku yaal dusha sare ee marada aan tolka lahayn, biyuhu waxay si toos ah uga soo qulquli doonaan dusha sare.
Marka labaad, iska caabinta heerkulka sare. Sababtoo ah barta dhalaalaysa ee polyesterku waxay ku saabsan tahay 260 ° C, waxay ilaalin kartaa xasilloonida cabbirka dharka aan tolmada lahayn ee hoos yimaada deegaanka caabbinta heerkulka. Si weyn ayaa loogu isticmaalay daabacaadda wareejinta kulaylka, shaandhaynta saliidda gudbinta, qaarna waxay u baahan yihiin iska caabin heerkul sare oo walxaha isku dhafan.
Saddexaad, poliester (PET) dharka aan toliyaha lahayn ee spunbonded ayaa ah kan labaad oo kaliya marka loo eego nayloon ka samaysan maro aan tol lahayn oo ah maro aan tol lahayn. Xooggeeda aadka u wanaagsan, guryaha neefsashada wanaagsan, iska caabinta jeexjeexa jeexjeexa iyo guryaha ka hortagga gabowga ayaa waxaa adeegsaday dad aad u tiro badan oo dhinacyo kala duwan jooga.
Afaraad, poliester (PET) maro aan tol lahayn oo duuban sidoo kale waxay leedahay hanti jireed oo gaar ah: iska caabinta fallaadhaha gamma. Si kale haddii loo dhigo, haddii lagu dhejiyo alaabada caafimaadka, waxaa si toos ah loogu jeermi karaa fallaadhaha gamma iyada oo aan waxyeello u geysanayn muuqaalkeeda jireed iyo xasilloonida cabbirka, taas oo ah hanti jireed oo aan lahayn polypropylene (PP) oo ka samaysan dhar aan tolnayn.

Farqiga u dhexeeya PP-ga dharka aan timaha lahayn iyo PET-ga aan-dhogorta lahayn

PP waa wax cayriin polypropylene, kuwaas oo fiber polypropylene, iska leh dhar khafiif ah oo aan tolmo lahayn; PET waa walxo cusub oo polyester ah oo ceyriin ah, kuwaas oo ah fiber polyester, habka wax soo saarka oo dhan iyada oo aan wax lagu darin, waa wax soo saarka ilaalinta deegaanka oo aad u wanaagsan, kana tirsan dhar dhumuc weyn leh.
(PP) polypropylene maro aan-tod lahayn iyo (PET) polyester-ka isbarbardhigga dharka aan-xidhka lahayn:
1. Qalabka cayriin ee PP waa raqiis, alaabta ceeriin ee PET waa qaali. Qashinka PP dib ayaa dib loogu warshadayn karaa foornada, PET dib loo warshadayn karo, markaa qiimaha PP wax yar ayaa ka hooseeya.
2. PP iska caabin heerkul sare ah oo ku saabsan 200 darajo, iyo PET oo ku saabsan 290 darajo, PET ayaa aad uga adkaysta heerkulka sare marka loo eego PP.
3. Daabacaadda aan timaha lahayn, saamaynta wareejinta kulaylka, balaadhka PP isku midka ah, hoos u dhaca PET, saameyn wanaagsan, PET waxay badbaadisaa qashinka yar.
4. Kacsanaanta, kacsanaanta, awoodda culeyska, culeyska garaamyada isku midka ah, PET marka loo eego xiisadda PP, xiisadda, awoodda culeyska. 65 garaam oo PET ah waxay u dhigantaa 80 garaam oo kacsanaanta PP, kacsanaanta, awoodda rarka.
5. Marka laga eego dhinaca ilaalinta deegaanka, PP oo lagu daray qashinka dib loo warshadeeyay, PET dhammaan xaleef polyester-ka cusub, PET ayaa deegaanka uga fiican kana nadiifsan PP.
