| Several of the masterbatch performance analysis | |
| Release time£º2016/9/23 | |
(1) the choice of the heat resistance of the pigment masterbatch, polypropylene fibers basic requirement withstand temperature during the production, to maintain its stable performance. Temperature requirements for the above temperature is generally 270 ~ 280 ¡æ.
(2) a pigment dispersion of masterbatch dispersion of fine should be, and to be uniformly dispersed in the masterbatch, and dispersant use does not reduce the quality of polypropylene fibers. Or can not produce a good quality liquid coloring fibers, running is not stable, easy to break or produce abnormal fibers during drawing fibers.
(3) the brightness of polypropylene liquid color has many uses, including fabric and knitted fabric for bedspreads, requires bright colors. Because organic pigment relatively bright and vivid, and easy to color, it is used for such purposes where the need to use organic pigments.
(4) under the action of light resistance in light of some pigments sensitive to light, the colored fiber faded and brittle damage, and the pigment lightfastness basically related to its chemical structure, so in the production of masterbatch should give full attention to pigment lightfastness When pigment lightfastness need to use, you can consider adding an ultraviolet absorber.
