مواد رنگزای دیسپرس
Disperse dyes can be used for dyeing and printing polyester, acetate, triacetate, nylon and acrylic. The colour shade card contains information on various properties of application
These dyes are eminently used for making self shade as well as compound ones. They provide high tinctorial strength, good leveling and favourable reproducibility for dyeing and printing
Our disperse dyes can be classified into the following three groups
(E) Subzero type: Dyes which show excellent leveling property and are applied mainly at high temperatures
(SE) Medium temperature type: Dyes which show high fastness properties, especialy light fastness and are applied with any dyeing process
(S) High temperature type: Dyes which show excellent sublimation fastness and can sufficiently stand hard treatment processes after dyeing, such as pleat and permanent press finishing. They are applied mainly to high temperature dyeing, themosol dyeing and printing. Finally, dyes of our corporation are a series of disperse dyes which have been marketed for synthetic fibers, especialy polyester fibers
Dyeing methods
High temperature dyeing method *
A. Dyes :x% (o.w.f)
B. Leveling agent :0.5-1g/l
C. PH : PH 4.5-5 (adjusted with acetic acid 0.25 g/l and sodium acetate 1g/l)
Temp.,Time : Riase the temperature from 90c to 130c in 30-50 min and dye for 30-50 min at 130c
Liquor ratio : 1:10~30
Reduction clearing :Hydrousulfite cc.1g/l
Naoh (40 BE)2 m/l
Nonionic surfactant 1 g/l
Liqour ratio1:30
Temp,Time 85c X 10min
Dyeing procedure
Carrier dyeing method *
A.Dyes : x % (o.w.f)
B.Carrier : Carrier P cone 4g/l
C.PH : PH 4.5-5 (adjusted with acetic acid 0.25 g/l and sodium acetate 1 g/l)
Temp, Time : Raise the temperature from 50c to 100 c in 30 min and dye at the boil for 60-90 min
Others : Same as in high temperature dyeing
Printing method *
Material : Polyester fabric
Printing paste: Disperse dyes xg
Water : 250g
Stock Thickening (locust bean gum type) 550 g
reduction : 2 g
inhibitor (sodium chlorate)
Tartaric acid : 3 g
Balance (water or thickener) : y g
Total : 1000 g
For reduction printing depth, the above printing paste is mixed to the following reducing thickening
Reducting : Stock thickening 700 g
Thickening : Water 293 g
Reduction inhibitor 4 g
Tartaric acid 3 g
Total 1000 g
Proced: Printing → Drying → H.P.Steaming (130 c × 30min) → Rinsing → Reduction clearing → Rinsing → Dryeing
Thermosol dyeing method *
Material : Polyester fabric
Dyeing depth : X g/l
Migration inhibitor Sodium alginate 1 g/l
Proced : Preparation of padding liquor → Padding → ureSqueezing (Pick-up 60-70%) → Intermediate drying (110 c × 60 sec) → Thermosoling (180 c ~ 220 c × 90sec) → Rinsing → Reduction clearing → Rinsing → Drying
