He aha ka ʻokoʻa ma waena o ka mea PP a me ka polyester?

1. ka nānā 'ana i nā mea

ʻO ka lole PP non-woven: ʻO ka fiber i hoʻohana ʻia no ka hana ʻana i ka lole i ulana ʻole ʻia he polypropylene, ʻo ia ka fiber synthetic i loaʻa ma ka polymerization o propylene.

ʻO ka lole polyester non-woven: ʻo ka fiber i hoʻohana ʻia no ka hana ʻana i ka lole non-woven he polyester fiber, ʻo ia ka fiber synthetic i loaʻa ma ka wili ʻana i ka polyester condensed mai ka waika dibasic organik a me ka diol.

2. Nā ʻano like ʻole

ʻO ka lole PP non-woven: ʻO 0.91g/cm3 wale nō kona mānoanoa, ʻo ia ka ʻano māmā loa ma waena o nā fiber kemika maʻamau.

ʻO ka lole poliester nonwoven: I ka piha ʻana o ka polyester i ka amorphous, ʻo kona mānoanoa he 1.333g/cm3.

3. ʻOkoʻa kukui kū'ē

ʻO ka lole ʻaʻole i ulana ʻia ʻo PP: ka pale ʻana i ka māmā maikaʻi ʻole, ka pale ʻana i ka insolation, ka maʻalahi o ka ʻelemakule a me ka nalo.

ʻO ka lole polyester non-woven: maikaʻi ke kūpaʻa māmā, 60% wale nō ka nalowale o ka ikaika ma hope o ka hoʻomālamalama ʻana o ka lā 600h.

4. Nā mea wela like ʻole

ʻO ka lole ʻaʻole i ulana ʻia ʻo PP: maikaʻi ʻole ka wela wela, ʻaʻole kū i ka hao.

ʻO ka lole polyester non-woven: maikaʻi ke kūpaʻa wela, ka helu heheʻe ma kahi o 255 ℃, a me ke ʻano paʻa ma lalo o kahi ākea o nā kūlana hoʻohana hope.

5, kū'ē alkali like 'ole

Polypropylene non-woven lole: Polypropylene maikaʻi ke kūpaʻa kemika, a ma waho aʻe o ka caustic soda, polypropylene maikaʻi ke kūpaʻa alkali.

ʻO ka lole polyester non-woven: ʻAʻole maikaʻi ke kūpaʻa alkali o ka polyester, hiki ke hōʻino i ka fiber ke hana ʻo ia me ka alkali koʻikoʻi ma ka lumi wela a hoʻoheheʻe i ka alkali i ka wela kiʻekiʻe.He paʻa wale nō ka hoʻoheheʻe ʻana i ka alkali a i ʻole ka alkali nāwaliwali ma ka wela haʻahaʻa.
