Maopopo anei iā ʻoe nā ʻeono mea nui kemika? (Polypropylene, Vinylon, Spandex)

I ka honua o nā fibers synthetic, vinylon, polypropylene a me spandex nā mea āpau a me nā mea hoʻohana e kūpono ai i nā ʻano huahana a me nā ʻoihana.

Kūlana ʻo Vinylon no kona hoʻomoʻa ʻana i ka wai kiʻekiʻe, e lilo ia i mea maikaʻi loa ma waena o nā fiber synthetic a loaʻa iā ia ka inoa i kapa ʻia ʻo "synthetic cotton." ʻO kēia waiwai hygroscopic he mea kūpono ia no ka hoʻohana ʻana i nā huahana like ʻole e like me muslin, poplin, corduroy, underwear, canvas, tarps, packaging material and workwear.

ʻO ka polypropylene fibers, ma ka ʻaoʻao ʻē aʻe, ua manaʻo ʻia ʻo ia ka māmā loa o nā fibers kemika maʻamau a hoʻomoʻa liʻiliʻi i ka makū. He mea kūpono kēia no nā ʻano noi like ʻole, me nā pūkini, nā ʻupena makika, nā quilts, nā mea hoʻopiha wela a me nā diapers. Ma ka ʻoihana, hoʻohana ʻia ka polypropylene i nā kāpeti, nā ʻupena lawaiʻa, ke kāwele, nā paipu wai, a me ka lipine lāʻau lapaʻau e hoʻololi i ka gauze pulupulu a hana i nā huahana maʻemaʻe.

I kēia manawa, ʻike ʻia ka spandex no kona elasticity kiʻekiʻe, ʻoiai ʻoi aku ka liʻiliʻi o ka hygroscopic a ʻoi aku ka ikaika. Eia nō naʻe, he kūpaʻa maikaʻi ʻo ia i ka māmā, ka waikawa, ka alkali a me ka abrasion, e hoʻolilo iā ia i fiber elastic kiʻekiʻe e pono ai no nā lole hana kiʻekiʻe e hoʻokumu i ka dinamika a me ka maʻalahi. Hoʻohana ʻia kāna mau noi i nā ʻāpana textile a me nā lāʻau lapaʻau, a ma muli o kāna mau waiwai kūʻokoʻa, hiki ke hoʻohana ʻia i loko o ke kapa komo, lingerie, nā lole maʻamau, nā lole haʻuki, nā socks, pantyhose a me nā bandage.

He hana koʻikoʻi kēia mau fiber synthetic i nā ʻoihana like ʻole a hāʻawi i kahi ākea o nā koho i nā mea hana a me nā mea kūʻai aku. Inā ʻo ia ka waiwai hygroscopic o vinylon, ka māmā a me ka mahana o ka polypropylene, a i ʻole ka elasticity o spandex, hoʻomau kēia mau fiber i ka hana a me ka hana o nā huahana mai nā lole a i nā lako olakino.
