ʻIkepili o nā pilikia paʻakikī i ka hoʻoluʻu ʻana i ka fiber Spandex

Ua ʻike maopopo ʻia e hiki ke hoʻoluʻu ʻia ka fiber spandex me nā disperse dyes a me ka waika, akā maikaʻi ʻole ka wikiwiki o kēia mau pena ʻelua.Ua hōʻoia ka hapa nui o nā hoʻokolohua ʻaʻole waiho nā waihoʻoluʻu reactive no ka nylon a me ka disperse cationic dyes ma ka spandex.Hōʻike anei kēia ʻaʻole kūpono nā mea pena ʻelua no ka pena spandex?ʻOiaʻiʻo, ʻaʻole pēlā.Me ka catalysis o nā mea kōkua kūpono, hiki ke hoʻohana ʻia nā dye reactive no ka nylon no ke kala ʻana i ka spandex, a ʻoi aku ka maikaʻi o kona wikiwiki a me ka hohonu.He kikoʻī kikoʻī kēia.

1. He kakaikahi na lole spandex ma'ema'e ma ka makeke, no laila, 'a'ole i ma'a iā mākou ke kala o ka spandex.Hiki ke hoʻohanaʻia nā lole spandex maʻemaʻe me nā lole elastic haʻahaʻa a iʻole nā ​​lole inelastic, hiki ke hoʻonui i ka elasticity a me ke kūpaʻa o nā lole.A i ka wā e kikoo ʻia ai ka lole elastic, inā ʻaʻole kūlike ke kala o ka fiber spandex me ka filament, aia ka pilikia o ka leakage kala o ka spandex, kahi e koi ai i ke kala o ka spandex.

2. No ka waihoʻoluʻu māmā o ka spandex, hiki ke hoʻohana i ka waiʻawaʻawa a i ʻole ka disperse dye i loko o nā kūlana wai ʻauʻau.Ma lalo o ke ʻano o ka hoʻohana ʻana i ka mea pena like, ʻoi aku ka wikiwiki o ka disperse dye ma mua o ka acidic dye ma ka spandex, akā ʻokoʻa ka wikiwiki o nā disperse dye ma ka spandex.Ma keʻano laulā, inā ʻoi aku ka liʻiliʻi o ka nui o ka dye ma mua o 0.5%, hiki ke hoʻohana ʻia nā disperse dyes.

3. ʻO Spandexfiber ka fiber elastic kiʻekiʻe.Ke noʻonoʻo nei ʻo ke kala ʻana i ka spandex no ka manawa lōʻihi ma lalo o kahi wela kiʻekiʻe e alakaʻi i ka hiki ʻole o ka elastic, ʻo ia ka mea maʻamau ma lalo o 100 ℃.ʻO ka mea hou aku, ʻaʻole kūpaʻa ka spandex i ka alkali, a ʻo nā mea hoʻoheheʻe disperse a me nā wai waika e kūpono no ke kala ʻana i nā kūlana acidic.Ma keʻano laulā, mālama ʻia ke kala ʻana o ka spandex i nā kūlana acidic me kahi pH ma kahi o 5.

4. Hiki ke hoʻohana ʻia nā ʻano kala like ʻole, me nā mea kōkua kūpono e like me nā mediums, e hoʻoluli i ka fiber spandex.Ua kapa ʻia kēia ʻano o nā mea kōkua i ka mākeke spandex color agent a i ʻole spandex colorant, ka mea i hoʻohana nui ʻia no ka make ʻana o nā dyes reactive no ka nylon a me nā dyes acid ma spandex, ka mea maʻamau e kaena i nā waiwai amphoteric ion.He oolea ka loina hana penei: Ma lalo o na kulana acidic, ka amide bond a me na hui e ae o ka spandex ionize, me ka uku maikai, a hiki i ka hopena me ka spandex colorant.A laila hoʻopaʻa ʻia ka mea hoʻoponopono i loko o ka spandex no ka mea ʻo ka spandex colorant he amino positive ions, hiki ke hui pū ʻia ke kala a me ka spandex colorant.

5. Nā lula maʻamau o ka hoʻokē ʻai ʻana ma hope o ke kala ʻana i ka spandex: Holoi > ʻeleʻele hou (acid) > pulu, a ʻoi aku ka maikaʻi o ka hamo ʻana o ka pūnaewele ma mua o ka hamo maloʻo.
