(1) Heat resistance masterbatch pigment chosen, a basic requirement, endure polypropylene fiber production process temperature, stable performance. Temperature and temperature generally require more than 270 ~ 280 ¡æ.
(2) a pigment dispersion excellent in dispersibility masterbatch, and the masterbatch dispersion, a dispersing agent used and the quality of cotton fiber does not decrease. Otherwise, poor production quality liquid coloring fibers run, is not stable, traction fiber breakage and abnormal fibers.
(3) The brightness of cotton colored liquid to be used a variety of uses, its linen fabric and knitting requirements, bright colors. Organic pigments relatively bright, bright colors, and easy to the above uses, generally do not use organic pigments.
(4) under the action of light resistance, light colored fibers some color photograph effect faded, brittle loss of basic pigment lightfastness and chemical structures. Therefore, to give full attention to the production of pigment lightfastness masterbatch, pigment lightfastness use in considering the need to add an ultraviolet absorber.
(5) the stability of the pigment color masterbatch cotton fiber excellent stability. That colored fiber polymer prolonged exposure to heat, light and not heat to form pigments and fibers, reducing the performance of the new chemical groups of the polymer. Therefore, the selection of masterbatch in order to become net pigment, free of iron, copper, lead and salt impurities, coloring ensure excellent physical properties of cotton fiber.
(6) water resistance, dry resistance, oil resistance, colored cotton fiber products to avoid the use of water and solvent cleaning, after contact with oil, especially when the carpet, stains using a good water resistance, washing laundry sex, oil resistance.
