What is the general addition amount of calcium carbonate filled masterbatch to non-woven fabric? Compared with injection/blowing, what are the special requirements? Please expert guidance, thank you!
The three major fibers used in the production of nonwovens are polypropylene fibers (62% of the total), polyester fibers (24% of the total) and viscose fibers (8% of the total). Between 1970 and 1985, viscose fiber was the most widely used in the production of non-woven fabrics. However, in the past five years, the application of polypropylene fiber and polyester fiber has begun to dominate in the field of sanitary absorbent materials and medical textiles. In the early days of nonwovens production, nylon was used in large quantities. Since 1998, the amount of acrylic fiber has started to rise, especially in the field of artificial leather manufacturing.
The non-woven fabric is generally made of PP material, and the filling material is the same as the textile bag filling.
Filling masterbatch for polypropylene woven bags (or polypropylene pipes) Â Â
 Formula composition (parts by mass) of random polypropylene (APP)            35
Calcium carbonate                     65
Titanate coupling agent TTS Â Â Â Â Â Â Â Â Â Â 1 .0
Stearic acid (HSt) Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â 2
Polyethylene wax                   0.5   Â
Processing conditions  APP softening point is low, the effect of coating filler is better, but the strength of the product is lower; among them, calcium carbonate can be used for hydrogen type or heavy type, but all must be coupled beforehand, and then mixed with APP and other additives. .

Fully Drawn Yarn(FDY), the polyester filament
with high orientation degree which is obtained from melt direct spinning or
chips by one-step drawing process, has the characteristics of high orientation
degree, good smoothness, good weaving unwinding and good dyeing uniformity. We
use German BARMAG spinning line produce microfilament yarn.
Categories:
semi dull, trilobal bright,
cationic yarn.
Application
Mainly used in the production of garment fabric and decorative fabric, suitable for rapier looms, water jet loom, air jet loom, circular knitting, warp knitting machine.
Typical products are suit fabric, corduroy fabric, silk-like quilt cover, silk-like tie, curtain and sofa cloth etc.
