Poy Ua Zoo Cov Chij Liab: 5 zais zais qhov tsis xws luag uas tuaj yeem tsim koj ntau lawm

Ib qho Bangladesh Cheater Tsis ntev los no Poob $ 480, 000} thaum lawv cov poy zaub mov xa tuaj crystalline spikes - undetectable los ntawm tus qauv ISO 2062 kev ntsuam xyuas. Qhov no cov kab tsuag tseem ceeb hauv Poy Tswjhwm Zoo.

Kev Puas Tsuaj 1: Kev Qhia Txog Kev Sib Tw
Tshwm sim los ntawm:

Temperature fluctuations >± 3 Degree hauv nqaj nqaj

Cov Huab Cua Tsis Muaj Huab Cua Flow Flow (Zoo Tshaj Profile: Fig.3)
Nrhiav tau: Yuav tsum muaj cov tshuaj ntsuam xyuas DSC (saib rau ntau tm peaks)

Kev kho mob 3: Oligomer tsim khoom
Peb cov kev kuaj sim seb:

POY stored >6 lub hlis tsim 0. {9-1. 7% oligomers

Ua rau 23% txo hauv kev kos cov nru ruaj khov

Tus 'stealth killer'
Micro-denier variations (>2.8% CV) ua rau:

Warp Beach Bugrations thaum texturing

17% cov neeg tawg tau ntau dua hauv cov dav hlau-dav hlau lo

Kev tiv thaiv kev ntsuas

Siv inline raman spectroscopy

Tswj {45-50% rh nyob rau hauv cia

Siv cov tshuaj tiv thaiv kab mob rau winding
