Polypropylene fiber spinning color master batch

Abstract

The invention discloses a polypropylene fiber spinning color master batch. A master batch matrix comprises a master batch main ingredient, a dispersing agent and a dispersing carrier, wherein the particle size of pigment particles in an aggregate form is 75-250 microns, more than 90% of pigment particles in the aggregate form are smashed and refined until the particle size is less than or equal to1 micron, so that the master batch main ingredient is obtained, the dispersing agent is polyethylene wax with CPSS140 DEG C of 1300-1550 and high molecular weight, and the dispersing carrier is polypropylene resin with MFI less than or equal to 20 and high molecular weight. More than 90% of pigment particles are smashed and refined until the particle size is less than or equal to 1 micron, so that the master batch main ingredient is obtained, and the dispersing agent is promoted to have more enough time to wet red and blue pigments. The polyethylene wax with the high molecular weight is beneficial to prolonging of dispersion time, pigment condensates and aggregates are wrapped and wetted more fully, a high-dispersibility and high-concentration master batch matrix is realized, and decisiveeffect is played for obviously improving product quality of red and blue bicolored yarns, reducing production cost and improving production efficiency of each link.

Description

technical field [0001] The invention relates to the technical field of polypropylene spinning, in particular to a polypropylene spinning color masterbatch. Background technique [0002] At present, in the polypropylene spinning process, the production technology and product quality problems caused by the quality of masterbatch are still the main aspects, and the situation is more prominent in the two colors of red and blue. The root cause is that the red and blue pigments have serious technical bottlenecks in the dispersion of toner, mainly manifested in the fact that the dispersion is not easy to control, instantaneously sticks or retains a large amount of raw powder; the uniformity of dispersion between each pot of material is different Serious; the stability and continuity of the base material granulation production is poor, the primary filtration and secondary filtration are boosted, and the filter screen is replaced frequently. In terms of spinning, the replacement cyc...

Problems solved by technology

The root cause is that the red and blue pigments have serious technical bottlenecks in the dispersion of toner, mainly manifested in the fact that the dispersion is not easy to control, instantaneously sticks or retains a large amount of raw powder; the uniformity of dispersion between each pot of material is different Serious; the stability and continuity of the base material granulation production is poor, the primary filtration and secondary filtration can boost pressure, and the filter screen is replaced frequently

Reflected in spinning, the replacement cycle of spinning components is less than two days, color difference often occurs before and after plate replacement, serious stiff yarn, severe end breakage
