The usage of calcium carbonate in Spunbond nonwoven fabric making line

In order to lower cost, some additives is usually added in pp spunbond nonwoven fabric making machine in the production process of PP spunbond nonwoven fabrics. And the calcium carbonate is a common additives/filler because of its economic and efficient advantages. This paper will mainly discuss the characteristics of calcium carbonate filler and the proportion used in the production of pp spubond nonwoven fabrics.

Calcium carbonate master batch is an kind of additive made by high purity calcium carbonate powder with plastic carrier (polypropylene PP). It is a white or near-white granular material with good dispersion and processing properties.

Calcium carbonate plays multiple roles in the production of PP spunbond nonwoven fabric. It can be used as a Filler to increase the volume and thickness of the nonwoven fabric. Secondly, calcium carbonate filler can reduce the production cost of nonwoven fabric and improve market competitiveness. The unit price of calcium carbonate masterbatch is 0.35USD/KG. The unit price of polypropylene pellets is 1.1USD/KG.

The Calcium carbonate adding percentage is usually 5-30% in the production of spunbond nonwoven fabrics. But for different markets and uses, the proportion is as high as 70% sometimes. With the vigorous development of the nonwoven fabric market, the demand for calcium carbonate filler is bound to rise. Through scientific and accurate grasp of the calcium carbonate addition ratio, it can help non-woven fabric factories to produce nonwoven fabric rolls with excellent performance and reasonable cost to meet the diversified needs of the market.

HG series spunbond nonwoven machine can add filler ratio from 5% to 80%, and the nonwoven machine could still work very stably with producing endless filament smoothly. Our spun bond non woven production line adopts the most advanced spinning components, and the diameter of the spinning nozzle diameter increased to 0.45mm-0.50mm; The fiber stretching device with height of 2.0 meters, which prevents the filaments draft efficiently.

Meanwhile,HG technical team will also provide professional operation training service ensure that each customer can skillfully operate the nonwoven fabric production line.
HG team has accumulated professional experience with numerous nonwoven fabric production projects and understand well the spunbond nonwoven fabric market in various countries. We can provide the best one-stop solution for global nonwoven fabric manufacturers.
