A. Environmentally friendly direct dyes Buy Yard Flags
Direct dyes in the dye disabled in the majority, in recent years, the development of environmentally friendly direct dyes have become the focus of the development of new varieties of the dye industry. Beach Warning Flags For Sale Specific varieties of direct dyes are the following:
(1) diamino stilbene disulfonic acid direct dyes: These dyes bright color fastness moderate, of GGL (CI Direct Orange 39) Direct Fast Orange is the better performance of the eco-friendly dyes. The triazole direct dyes Direct Yellow 3BLL (CI Direct Yellow 106), light fastness resistance of 6 to 7. Direct fast green, the IRC (CI Direct Green 34) dyeing rate, excellent color fastness, light fastness resistance of 6 to 7, the washing fastness of 3 4. Buy Yard Flags
(2) 4.4 '- diamino diphenyl urea class of direct dyes: These dyes are non-carcinogenic, high light fastness. The application of more varieties, is environmentally friendly dyes. Such as direct fast yellow RSC (CI Direct Yellow 50), Direct Fast red F3B (CI Direct Red 80), CI Direct Brown 112, CI Direct Brown 126, CI Direct Brown 152 and so on.
(3) 4.4 `- two the aminobenzoyl for aniline direct dyes: Buy Yard Flags These dyes fastness is better, environmentally friendly dyes. Such as direct green of NB (CI Direct Green 89), direct yellow brown the N-the D
(4) 4.4 `- Diaminobenzenesulfonanilide directly for aniline dyes: These dyes are two amino compounds to the synthesis of black direct dyes, dyeing properties and fastness are good. It is widely used in cotton, hemp, viscose, silk, leather dyeing. Has been developed and screening alternative to disable the direct dye products, such as CI Direct Black 166 (Direct Black N-BN), CI Acid Black 210 (Acid Black NT), CI Acid Black 234.

(5) two amino heterocyclic direct dyes: These dyes are two amino heterocyclic compounds synthesis of direct dyes, such as dibenzodioxins triazine class of direct dyes, these dyes bright color, high color strength and color fastness light fastness resistance 7. Representative species of CI Direct Blue 106 (direct fast blue FF2GL), Buy Yard Flags CI Direct Blue 108 (direct fast blue FFRL).
(6), one-bath dyeing of environmentally friendly direct dyes: polyester / cotton, polyester / rayon blended fabric such as polyester / cotton fabric (polyester / rayon) with fibers of different nature, which require direct dyes with excellent high temperature stability, with good lifting power and reproducibility, better fastness and environmental performance. Direct blending of the Shanghai dye developed by D-type dyes, can reach the performance of environmentally friendly dyes, Wind Flags Advertising the species has reached more than 25 kinds, such as CI Direct Yellow 86 (direct blending yellow DR), CI Direct Yellow 106 (direct blending yellow D -3RLL), CI224 directly blended red D-GLN, CI Direct Violet 66 (direct blending purple D-5BL), Buy Yard Flags CI Direct Blue 70 (direct blending blue D-RGL), CI95 direct blend Brown D,-RS, Swooper Feather Flags Wholesale CI, directly Black 166 (direct blending black D-ANBA). Individual varieties of copper complexes free copper in the the ETAD prescribed limits (250mg/kg) within.
(7) the development and screening of the Nippon Kayaku Kayaeelon C-type dyes: CI Direct Yellow 161 (Yellow C-3RL), CI Direct Red 83 (Rubine C-BL), CI Direct Blue 288 (Blue C-BK) CI Direct Green 59 (Caeen C-CK), CI Direct Black 117 (Crey the C-RL) and so on.
The Dystar Company has developed of Sirius Plus Series direct dyes, Ciba launched Cibafix the ECO direct dyes, the BASF to launch Diazol series of direct dyes, the Yorkshire the launch Benganil series direct dyes. These dyes have a similar function, such as bright color, high light fastness, environmentally friendly dyes free of heavy metals, and has excellent high temperature stability, suitable for a bath one step dyeing of polyester-cotton blend fabric.
Two. Environmentally friendly acid dyes Buy Yard Flags
(1) red, orange, yellow acid dyes in the development of acid green dye in the red acid dyes: CI Acid Red 37, CI Acid Red 89 (Acid Red 3B, 2BS), CI Acid Red 145 (weakly acidic red GL ), etc. CI Acid Red 336 and CI Acid Red 361 are important species of the red spectrum. Orange acid dyes: CI Acid Orange 67 (Acid Yellow RXL), CI Acid Orange 116 (Acid Orange of AGT), CI Acid Orange 156 (weakly acidic orange
(2) blue, green, purple acid dyes blue spectrum of environmental acid dyes are mostly bromine acid derivatives, the blue more new varieties, such as CI Acid Blue 277, CI Acid Blue 344, CI Acid Blue 350, CI Acid Blue 9 (Brilliant Blue FCF) and so on. Green acid dyes, anthraquinone, the country has developed new products CI Green 17, Buy Yard Flags CI Acid Green 28, CI Acid Green 41, CI Acid Green 81 and so on. The purple main CI Acid Violet 17 (acid the purple 4BNS), CI Acid Violet 54 (Weak Acid Red 10B), CI Acid Violet 48.
