Kusintha kwa Anhydrous Coloring Njira ya Polyamide 6 Ulusi

Tsopano, kukakamizidwa kwa chitetezo cha chilengedwe kukuwonjezeka.Ulusi wa nayiloni umalimbikitsa kupanga zinthu zoyera, ndipo njira yopaka utoto wopanda madzi yakopa chidwi kwambiri.M'munsimu muli chidziwitso chofunikira cha njira yopangira utoto wopanda madzi.

1. Njira yopangira utoto wa nayiloni 6

Pakadali pano, utoto wa ulusi wa thepolyamide mumakampani a nayiloni aku China umagwiritsidwa ntchito kwambiri popaka utoto wothira ndi utoto wam'mapadi kumapeto kwa kupota.Utoto womwe umagwiritsidwa ntchito umaphatikizapo utoto wobalalitsa ndi utoto wa asidi.Njirayi sikuti imangosiyanitsidwa ndi madzi, komanso imakhala ndi mphamvu zambiri komanso ndalama zambiri.Kuipitsa kwa kusindikiza ndi kudaya madzi otayidwa pambuyo pake ndikovuta kwambiri.

Pigment imagwiritsidwa ntchito ngati chopangira utoto pokonzekera mtundu wa masterbatch, womwe umasungunuka ndi tchipisi ta ulusi wa nayiloni 6 kuti upeze ulusi wamtundu wa nayiloni 6.Kuzungulira konseko sikufuna dontho la madzi, ndipo kumakhala kobiriwira komanso kosakonda zachilengedwe.Ndi njira yogwiritsidwa ntchito kwambiri yomwe yatulukira m'zaka zaposachedwa, koma siinali yangwiro ponena za spinnability ndi kusanja katundu.

Njira yopangira utoto wa vacuum sublimation imagwiritsa ntchito utoto wobalalitsa kapena inki yosinthika mosavuta ngati utoto, womwe umalowetsedwa mu gasi pansi pa kutentha kwambiri kapena mpweya wabwino, wokongoletsedwa pamwamba pa ulusi wa nayiloni 6 ndikufalikira mu ulusi kuti amalize utoto.

2. Ubwino wa nayiloni 6 ulusi wopanda madzi

Izi sizimadya madzi, koma pali mitundu yochepa chabe ya utoto ndi inki yomwe ingagwiritsidwe ntchito kupaka ulusi wa nayiloni 6.Kuwongolera kwa liwiro la sublimation kudzakhudza kuchuluka kwake komanso kutengera utoto kumlingo wina, womwe umafunikira zida zapamwamba.Ngakhale kuti palibe vuto la kuipitsidwa kwa madzi, kuipitsidwa kwa zipangizo, chilengedwe ndi ogwira ntchito sikunganyalanyazidwe.

Supercritical carbon dioxide dyeing siwononga madzi.Utoto wa Hydrophobic disperse ukhoza kusungunuka mu carbon dioxide wochuluka kwambiri kuti ukhale ndi utoto wa nayiloni.Poyerekeza ndi utoto wamadzi, nthawi yopaka utoto ndi yaifupi.Pokhapokha pokonza kupanikizika ndi kutentha, njira yonse yopaka utoto imatha kutsirizidwa pa chipangizo chimodzi, koma sichikhoza kuthetsa bwino zotsatira za oligomers pa ntchito yopaka utoto pa nthawi ya utoto.
