Muaj plaub pawg: (1) Puv -pair -pair -pair -pair -pair -pair -pair -pair -pair -pair -galmide pawg fiber ntau; (3) Puv-bonuscanamide fiber ntau; (4) Essence Thawj ob pawg yog siab zog thiab high-profile tshav kub-resistant fibers, thiab tom kawg ob yog siab-temperature resistant thiab nyuaj rau ignite fibers.
Cov txheej txheem ntawm qhov system siv qhov ntsuas kub qis rau kev thim rov qab. Ntawm lawv, chav kawm (1) yog cais cov polymer thiab yaj hauv cov concentrated sulfuric acid qhuav tshuaj tsuag ntub dej. Yog tias tsim nyog, nws tuaj yeem kho tau. Cais cov polymer, thiab tom qab ntawd yaj cov spinning, thiab ncaj qha ntub cov ntaub ntub dej thiab ncab los ntawm (3) thiab (4).
Kev siv (1) thiab (2) yog siv los siv kev siv lub zog siab thiab kev ua haujlwm siab ntawm chav tsev kub thiab kub kub hauv chav tsev kub thiab kub.
