④. Better sunlight fastness and washing fastness, smaller particles ( 95% pigment particles is less than 0.5μm), uniformly particle distribution;
⑤. Lower impurity content, stable performance.
⑥. And CTH-X00X series water based pigment paste has better performance in the color fastness of high temperature resistance, color discharge resistance, migration resistance, perspiration and saliva resistance;
3. Instructions for using
①. Inspection conditions description on formaldehyde, heavy metals, phthalates, 24 kinds of prohibited aromatic amines and APEO: all of tests are depending on the full cotton fabric printed by water based paste or rubber paste which all is prepared by 10% adding amount of pigment color paste. If exceeding the above operated conditions, please make the small sample testing first and get the qualified, then use it in mass production.
②. Our products are eco-friendly pigment paste. When use them with other auxiliaries and materials, please consider the environmental issues, no residue limited substances on operated equipment, in order to avoid secondary pollution causes environmental risks;
③. Please stir the pigment paste evenly before using. If any precipitation happened during the long time storage, it still can work when you can do enough stirring and filtering;
④. It is possible that the aromatic amine content may exceed the limited requirement when superimposed using CTH-XXX0 series water based pigment paste (mainly is red, yellow and brown). so please pay more attention to it during the using it, you can confirm it by sample testing, then start to mass production, in order to ensure the quality of printed products.
⑤. The red color and brown color from CTH-XXX0 series products are compatible with rubber paste for pressing and printing, original color changing, gradating phenomena or color infiltration will appear sometimes. Furthermore, the smaller amounts you added, the more easily it happened. Please refer to our testing results of migration resistance with rubber paste printing in color swatch, you can choose ones with good performance to have a test in small amount before using, in case that any quality problems mentioned above will happen. If CTH-XXX0 series products can’t meet your need, you can choose CTH-X00X series pigment paste products.
⑥. Some parts of CTH-XXX0 series water based pigment paste has poorer migration resistance, is not suitable for rubber paste printing.
4. Just reference formulation for application (mainly suitable for cotton and polyester cotton fabrics)
Printing process of water paste:
Desk screen printing → drying ( 100℃ for 3 minutes) → baking (150℃ for 2 minutes);
Printing process of rubber paste:
Desk screen printing → drying or blow-drying (80~100℃) → hot pressing (130~150℃，5~15sceonds);
This formulation is a general one. Customers should make some adjustments based on their owned processes.
5. Executive standard description of performance index in color swatch.
①. Performance of soap washing fastness GB/T3921-2008, dry-rubber resistance GB/T 3920-2008 and perspiration fastness GB/T 3922-1995, is measured by Shanghai Institute of Printing and Dyeing Technology according to the samples provided by us.
Printing process: Desk screen printing → drying (100℃，5 minutes) → baking (160℃，3 minutes);
Printed fabrics: plain weave cotton poplin.
②. Artificial light fastness GB/T8427-2008:
It is tested by ourselves, using full cotton printed fabric, the related instrument: Q-Panel Lab Products, xenon lamp aging tester (Q-SUN / 1000).
Printing process: desk screen printing →drying (100℃, 3 minutes) → baking (130℃, 2 minutes);
Printed fabrics: plain weave cotton poplin (water paste printing), knitted cotton fabric (rubber printing).
③. Hot pressing fastness GB/T6152-1997
It is tested by ourselves, make hot pressing on printed fabric by the ways of water paste printing and rubber paste printing. Instrument used: Hot press machine.
Printing process: desk screen printing → drying (100℃, 3 minutes) → hot pressing (180℃, 10 seconds);
Printed fabric: plain weave cotton poplin (water paste printing), knitted cotton fabric (rubber paste printing).
④. Migration resistance:
It is tested by us, make hot pressing on the fabrics after printed by white rubber paste and transparent rubber paste.
Printing process: rubber paste desk screen printing → hair dryer drying → overprinting white rubber paste
→ hair dryer drying → hot pressing (130℃, 3 seconds);
Printed fabric: knitted cotton fabric.
⑤. Color discharge resistance:
It is tested by us, make hot pressing on knitted cotton fabric which is dyed with reactive dyes and then printed by special discharge paste;
Printing process: rubber paste desk screen printing → hair dryer drying (100℃, 2 seconds) → hot pressing (150℃, 5 seconds);
Printed fabric: knitted cotton fabric (dyed by reactive dyes).
6. The level instructions of all performance index in color swatch.
Light fastness: 8 is the highest; other fastness: 5 is the highest;
"O" means recommended using; "△ " means using after tested; "X" means no recommended;
7. Special note
1. All performance index is tested by us under certain conditions, parts of them is entrusted to test by Shanghai Institute of Printing and Dyeing. In the actual using, the process conditions may different with our testing methods, it is recommended to try or actual measurement, to achieve the required standards before mass production. If customers use our products directly without any testing, all the consequence is not responsible by us.
2. If any other technical parameters needed, please feel free to contact our technical dept.;
3. The colors on the color swatch is general products, we can design special color paste for you, also provide color scheme for free;
4. The colors have different proportions on color swatch and hue displayed on the plain weave cotton poplin, so there is certain deviation with the electronic version;
