With the rapid development of China's economy, the chemical fiber masterbatch industry is also with great development in the development of the relevant industries, and the level of chemical fiber masterbatch production technology has also been unprecedented, and the application field is constantly expanding. However, due to the influence of Chinese traditional market competition model, product competitiveness is not strong, especially quality requirements. Especially the polypropylene manufacturers, more focus on the effects of fibrous masterbatch quality on polypropylene quality.

Dispersion of chemical fiber masterbatch in polypropylene fibers

 A polypropylene fibers with various colors, is a uniform dispersion of pigment particles in the polypropylene fibers, and the key is that the pigment particles are sufficiently refined, and are uniformly distributed (mixed) in the polypropylene fibers. Refining dispersion is to break the coagulating or agglomerate of the pigment, so that the particles are smaller, and the key is to uniformly disperse, the desired effect on the color, transparency, gloss, fiber strength, elongation, and aging of the polypropylene fibers. Sex, electric yield, etc. have an impact.

 Singlely, the particle diameter of the pigment is less than 1 um can be used for fiber or ultra-thin films, and greater than 5 um can cause no gloss of fiber surface, greater than 10 um, causes spots, bar, stripes, and with particle size The strength of the large fibers, the elongation of elongation continues to decline. The fine colored force is so strong, the better the dispersion, and the particle size is small to increase the surface, resulting in an increase in the covering force.

Since the pigment particle state has three types of native particles, the cohesion, the monolithic particles are larger particles (about 75-250 um) that are larger than the agglomerate, so the dispersion is required, and the dispersion of the so-called pigment is The process of disintegrating the reinstallment of the regiment.

The dispersion of the pigment is firstly the wetting of the pigment, coating the surface of the pigment, reducing the cohesiveness between the pigment, reducing the energy required to break the pigment group, followed by the powder of the pigment, and the leading pigment particles The free movement (impact stress) and the pigment coat are broken through the shear stress of the surrounding medium. After the pigment is dispersed, the particle size is reduced, the surface area is increased, and the free energy of the pigment also increases the fineness of the pigment, so that the coating treatment of a single step in the surface of the pigment is reduced. The interface surface can prevent re-aggregation, and then the pigment is mixed in the melt, so that the pigment to be wet and pulverized is uniformly dispersed into the material that needs to be colored.

What are the attention of the chemical fiber masterbatch?

(1) The chemical fiber-made granules will be absorbed, especially PET, ABS, PA, PC, etc., so the same process is carried out according to the same process in this color and reach a water content requirements.

(2) It is necessary to use the color of the color masterbatch to achieve the desired light color, and the change in color difference and color light will often occur.

(3) The chemical fiber parenta and other additives will react, pay attention to it.

(4) The selection of dilution ratio of chemical fiber parenta should be paid. The high dilution ratio is selected, and the cost is lower, but it is also subject to processing equipment.
