Nā hiʻohiʻona o nā disperse dyes:

ʻAʻole e like me nā ʻano mea pena ʻē aʻe, ʻoi aku ka liʻiliʻi o ka wai hoʻoheheʻe ʻia ma mua o nā mea pena ʻē aʻe e like me ka wai waika. No laila, ʻoi aku ka maʻamau o nā disperse dyes i ka wai ʻauʻau wai.Tamol NNʻoi aku ka maikaʻi o ka hana ʻana i ke kaʻina hana kala i nā wela kiʻekiʻe. ʻO ke kikoʻī, hāʻawi nā hāʻina ma kahi o 120°C a i 130°C i ka hana maikaʻi loa e hoʻopuehu i nā waiʻala, e hoʻohele like ʻia a ʻike ʻia ka maka, ʻoiaiTamol NNhiki ke hopena i ka waihoʻoluʻu like ʻole a emi ʻole ka waihoʻoluʻu i nā wela haʻahaʻa.

He aha nā mea hoʻohana o nā disperse dyes?Tamol NN

Ma muli o ko lākou mau waiwai kemika a me ke ʻano i hōʻike ʻia ma luna nei, hoʻohana maʻamau ʻia nā mea hoʻoheheʻe e hoʻolele i nā fiber synthetic, e like me ka polyester, nylon, acrylic, a me ka acetate. ʻO ka hapa nui o nā ʻano polyester he hydrophobic a nele i nā waiwai ionic, ʻaneʻane hiki ʻole ke kala me nā mea ʻē aʻe ma waho o ka disperse dyes.

Eia kekahi, ʻaʻole e hoʻonui ʻia nā fibers polyester i nā mahana maʻamau ʻoiai i ka wā i hoʻokomo ʻia i loko o kahi ʻauʻau wai, e paʻakikī ai i nā molekala kala e launa pū me ka mea. ʻOiai ma ka wela o ka paila (100°C), pilikia ke kala ʻana i ka polyester.

No laila, i ka wā e hoʻoluʻu ai i ka polyester, hoʻohana ʻia nā disperse dyes i ka wai ʻauʻau wai ma nā mahana 20 a 30 degere ʻoi aku ka kiʻekiʻe ma mua o ka paila o ka wai ʻauʻau wai. Ua ʻike ʻia nā disperse dyes e mālama i ko lākou molecular integrity i nā wela kiʻekiʻe e pono ai no ke kala ʻana i nā polyesters. No ke kumu hoʻokahi e hoʻohana ʻia ai nā disperse dyes e pena i nā polyesters, ua hoʻohana pū ʻia lākou e hoʻoluli i nā mea synthetic non-ionic ʻē aʻe. ʻO ka ʻoiaʻiʻo o ka disperse dyes ʻaʻohe cationic a i ʻole anionic tendencies ʻo ia paha ka waiwai nui loa o nā disperse dyes.

Hiki ke hoʻohana ʻia nā mea ʻulaʻula i loko o nā resins a me nā plastics no ka ʻili a me nā kumu kala maʻamau.
