Red pigment paste for textile printing，multifunctional water based pigment dispersion for coloring

CTH-2008 Orange red pigment paste for textile printing

1. Product Brief

Shanghai Caison CTH series eco-friendly water based pigment paste mainly includes CTH-X00X series ( High performance series) and CTH-XXX0 series (Normal series), they are suitable for printing or tinting of cotton, linen, polyester, acrylic and various blend fabrics, also for artificial leather dyeing; widely used in printing and dyeing of exporting textile, garment, fabrics, sheets, shoes, hats and artificial leather clothing.

2. Product Features

①. It conforms to Oeko-Tex100:2016(II Class) Standard of International Association for Research Testing in the field of Textile Ecology (contents restriction of formaldehyde, heavy metals, phthalates, APEO and 24 kinds of prohibited aromatic amine);

②. It conforms to National General Safety Technical Code for Textile Products GB18401-2010; compliance with the latest SVHC limits requirement of 168 kinds of substances in REACH regulations;

③. Color is rich and bright, now we have 46 normal colors of water based pigment paste for your choice, see details on CTH series pigment paste color swatch;

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.

Introduction of water based black pigment paste

Carbon black is very important and very common inorganic black pigment, which is widely used for inks, coatings, printing and dyeing applications. However,  special carbon molecular structure of carbon black leads to difficult to disperse and easy to agglomerate. So how to promote the good dispersion of carbon black in water based black pigment paste is one important research topic in the research of Shanghai Caison Technology Department.
