Performance requirements

Polypropylene is a pure hydrocarbon, the molecular chain contains tertiary carbon atoms, heat, light in the tertiary carbon atoms at the molecules easily cracked, so that the quality of polypropylene fiber deterioration, so the required masterbatch in high temperature spinning Easy to spread, does not damage the fiber quality, does not make the fiber fade, has excellent light resistance, wear resistance, solvent resistance, can withstand strict spinning draft.

(1) heat-resistant masterbatch selected pigments, the most basic requirements of the polypropylene fiber can withstand the production process temperature, to maintain its performance stability. Temperature temperature is generally required for more than 270 ~ 280 ℃.

(2) dispersible masterbatch pigment should be excellent dispersion, and in the masterbatch to be dispersed evenly, and the use of dispersants will not reduce the quality of polypropylene fiber. Otherwise it can not produce a good quality of the original liquid coloring fiber, running is not stable, easy to break in the draft fiber or produce abnormal fibers.

(3) Brightness Polypropylene liquid coloring has a variety of uses, which are used for bedspreads and knitted fabrics, requiring bright colors. Organic pigments are bright and bright, and easy to color, so that the use of organic pigments for the use of the above.

(4) light resistance in the light of some pigments have a photosensitive effect, so that the coloring fiber fade and fragile, and the light resistance of the pigment is basically related to its chemical structure, so the production of masterbatch should pay full attention to the light When the light-resistant pigment needs to be used, it is conceivable to add an ultraviolet absorber.

(5) stability of the masterbatch used in the pigment, the colored polypropylene fiber to have excellent stability. It is meant that the pigmented fiber polymer does not react with the fiber after a long period of contact with heat, light or at high temperatures, resulting in a new chemical group that renders the polymer low. So the masterbatch should be used as pure as possible pigments, non-iron, copper, lead and other salt impurities, to ensure that the physical properties of colored polypropylene fiber is excellent.

(6) water resistance, dry cleaning resistance, oil resistance, coloring of polypropylene fiber products used in and inevitably go through water or solvent dry cleaning, to contact with oil, especially for carpets, so the use of colorants Good washability, dry cleaning resistance, oil resistance.
