Paʻi puaʻa vs paʻi kala

Paʻi ʻana

ʻO ka mea i kapa ʻia ʻo ka paʻi ʻana, ʻo ia ke kaʻina hana no ka hana ʻana i ka mea pena a i ʻole ka pena i loko o ka paʻi kala, e hoʻohana ʻia ana i nā lole a me nā ʻano paʻi. No ka hoʻopau ʻana i ka paʻi textile, ʻo ke ʻano hana i hoʻohana ʻia i kapa ʻia ke kaʻina paʻi.

Paʻi Pigment

ʻO ka paʻi Pigment kahi ʻano paʻi kahi e hoʻopaʻa ʻia ai ka puaʻa ma luna o ka lole ma ke ʻano o ka polymer molecular kiʻekiʻe (adhesive) a me nā mea kala ʻole i ka wai (pigments) e hana i kahi kiʻi ʻoniʻoni ʻoniʻoni paʻa, ʻike a ʻaʻahu i ka lole.

Paʻi kala

Ma ke ʻano o ke ʻano o ka dye dyeing fiber, ʻo ka paʻi ʻana a me ke kala ʻana he like ia, koe wale nō i ka paʻi ʻana, ua hoʻopili ʻia ke kala o kekahi kala ma ka ʻāina i ka textile e like me nā koi o ke kumu, a ma hope o kekahi mālama ʻana, ʻo ka dye. kala i ka fiber, a laila loaʻa nā huahana i paʻi ʻia me hoʻokahi a ʻoi aku paha nā kala ma ka textile. No laila, hiki ke ʻōlelo ʻia ka paʻi ʻana he "local dyeing".

Kumu kala kala

ʻO ka paʻi puaʻa kahi ʻano paʻi e hoʻōki ai i ka hoʻopili ʻana mai ka hana ʻana i kahi kiʻiʻoniʻoni paʻa, akaka a paʻa i ka lole, i mea e hoʻoponopono ai i ka pena ma ka lole.

Nā mea kala kala

ʻO ke kala ʻana he kaʻina hana e loaʻa ai i nā mea textile nā ​​waihoʻoluʻu ʻālohilohi a paʻa ma o ke kino, kemika a i ʻole ka hui kino-kemika o nā mea pena (a i ʻole pigment) a me nā mea textile.

Nā pōmaikaʻi a me nā pōʻino

Paʻi Pigment

Pono:

•Hoʻohana maʻalahi, kaʻina hana maʻalahi, kiʻekiʻe o ka hana hana, hiki ke hōʻemi i ka hoʻokuʻu ʻana i ka wai

•ʻO ka chromatogram ākea, ka māmā māmā, nā laina paʻi maʻemaʻe a me nā hiʻohiʻona

•He kūpono ia no nā ʻano paʻi kūikawā, a hiki ke hoʻohana ʻia no ka hoʻokuʻu ʻana a me ka paʻi anti dyeing

•ʻO ka hoʻohālikelike kala maʻalahi a me ka hana hou ʻana o ka māmā kala maikaʻi

•He kūpono ia no ka paʻi lole o nā mea fiber like ʻole, ʻoi aku ka nui o nā lole i hui ʻia.

Nā hemahema:

• ʻAʻohe manaʻo o ka lima, ʻaʻohe maloʻo a me ka maloʻo maloʻo wikiwiki

• ʻO ka hoʻohana ʻana i ka ʻaila i loko o ka paʻi emulsified e hoʻohaumia i ka ea; ʻO ka hapa nui o nā monomers i hoʻohana ʻia no ka hoʻomākaukau ʻana i nā mea hoʻopili he mea ʻawaʻawa

• ʻAʻole like ka ʻōlinolino o ka waihoʻoluʻu e like me ka paʻi kala me ke ʻano like

• He mea maʻalahi ka ʻili a hoʻopaʻa i ka ʻupena

Ka paʻi ʻana i ka wai (e lawe ana i nā mea hoʻoheheʻe reactive ma ke ʻano he laʻana)

Pono:

• Nui nā ʻano like ʻole, nā chromatograms piha a me nā kala ʻālohilohi

• He mea maʻalahi ka hoʻomākaukau ʻana i ka paʻi kala, ka hana paʻi maʻalahi, ka hopena maikaʻi a me nā hemahema liʻiliʻi

• ʻO ka wikiwiki maikaʻi i ka mālama pulu

• ke kumu kūʻai paʻi haʻahaʻa a me ka hoʻohālikelike kala maʻalahi

Nā hemahema:

• ʻAʻole kūʻē ka hapa nui o lākou i ka chlorine, a haʻahaʻa ka helu hoʻoponopono. He pololei loa (affinity) kekahi o na mea hooluolu, he mea maʻalahi ke hoʻopaʻa ʻia ke kopa ʻana, ʻoi aku ka maikaʻi i ka paʻi ʻana i nā kala hohonu a mānoanoa.

ʻokoʻa:

ʻO ka ʻokoʻa nui ma waena o ka paʻi kala a me ka paʻi puaʻa ʻo ia ka hui ʻana o ka paʻi puaʻa me ka lole ma o ka hoʻopaʻa kino ʻana, ʻoiai ʻo ka paʻi kala e hui pono ʻia me ka lole e van der Waals force.

Hiki ke hoʻohana ʻia ka paʻi puaʻa no ka hana ʻana i nā lole fiber. ʻOi aku ka maikaʻi o ka paʻi ʻana i nā huila a me nā lole i ulana ʻia. He kaʻina hana maʻalahi, chromatography ākea, outline ʻano pua akā maikaʻi ʻole ka lima a me ka wikiwiki o ka hamo. ʻO kā lākou māmā māmā a me ka hoʻomaʻemaʻe hoʻomaʻemaʻe maloʻo maikaʻi, maikaʻi loa, no laila ua hoʻohana nuiʻia i nā lole hoʻonani, nā pale pale a me nā lole lole e pono ai ka holoi maloʻo.

Pehea e hoʻokaʻawale ai ma waena o ka paʻi kala a me ka paʻi puaʻa

Hiki ke ʻike ʻia ka paʻi ʻana a me ka paʻi kala ma ka hoʻohālikelike ʻana i ka ʻokoʻa paʻakikī ma waena o ka ʻāpana i paʻi ʻia a me ka ʻāpana paʻi ʻole o ka lole like. ʻOi aku ka paʻakikī o ka manaʻo lima o ka wahi i paʻi ʻia ma mua o ka wahi i paʻi ʻole ʻia, a ʻoi aku paha ka mānoanoa. Inā paʻi ʻia ka lole me nā kala, ʻaʻohe ʻokoʻa paʻakikī ma waena o ka ʻāpana i paʻi ʻia a me ka ʻāpana i paʻi ʻole ʻia.
