Paj rwb non-woven fabrics tuaj yeem degraded. Cov khoom siv raw ntawm feem ntau cov ntaub tsis-woven yog polypropylene. Nws cov qauv tshuaj tsis muaj zog. Cov saw hlau molecular yog yooj yim tawg thiab degraded. Nws nkag mus rau lub voj voog ib puag ncig hauv daim ntawv tsis muaj tshuaj lom. Lub hnab ntim khoom tsis-woven Nws tuaj yeem decomposed tag nrho hauv 90 hnub. Lub degree ntawm cov pa phem rau ib puag ncig tom qab muab pov tseg kuj tseem lub teeb.
nthuav dav:
Non-woven npuag yog ib hom non-woven npuag. Nws yog cov ntaub ntawv uas tsis yog-woven tsim los ntawm ncaj qha siv polymer chips, luv fibers los yog filaments los tsim fibers los ntawm airflow los yog machinery, thiab ces undergoes hydroentanglement, koob xuas nrig ntaus, los yog kub dov reinforcement. ntaub. Raws li muaj pes tsawg leeg ntawm non-woven fabrics, muaj polyester, polypropylene, nylon, spandex, acrylic, thiab lwm yam., uas tsis yooj yim rau degrade. Nws kwv yees tias nws yuav siv sij hawm ntau pua xyoo kom decompose.
