1. Кереш сүз
Non-woven fabric is made of man-made fibers. In recent years, with characteristics of moisture-resistance, lightweight, non-toxicity and low cost, non-woven fabric has gradually come into people’s view and has been widely used in many fields. Ultra-fine calcium carbonate, as a widely used inorganic powder filler, can be used in the production of non-woven fabrics. It can not only reduce production costs, but also improve the performance of non-woven fabric, so, the role of ultra-fine calcium carbonate in non-woven fabric is important. Generally speaking, the amount of calcium carbonate added should not exceed 5% of the product weight.
2. The role of ultra-fine calcium carbonate in non-woven fabric
Enhance material hardness
Adding a certain proportion of ultra-fine calcium carbonate can significantly enhance the hardness of non-woven fabric and make product performance more stable.
Improve tear resistance
Adding ultra-fine calcium carbonate during non-woven production can effectively increase the tear resistance of the fabric and improve its overall quality.
Increase flexibility
Adding ultra-fine calcium carbonate can make non-woven fabric softer and more elastic, suitable for certain special uses.
Reduce costs
As an inorganic and cheep powder filler, ultra-fine calcium carbonate can reduce production costs of non-woven fabric.
3. Index for calcium carbonate
When selecting calcium carbonate as filler for non-woven fabric, calcium carbonate with following index can be selected:
① Particle size: the preferred particle size is 4-8 um.
② Moisture: the general requirement is ≤0.5%.
③The higher the whiteness, the better. Generally, the whiteness is required to be ≥ 90%. The whiteness of high-quality calcium carbonate can reach more than 95%.
④The oil absorption value should be low, the reference value is ≦20-23g/100g.
4. Application
Non-woven fabric with added ultra-fine calcium carbonate is widely used in many fields, such as automotive interiors, mattresses, furniture and packaging materials. The addition of calcium carbonate can make non-woven fabric products stronger and more textured.
As a filler, the particle size and purity of ultra-fine calcium carbonate have an important impact on the performance of non-woven fabric. In order to ensure the quality and performance of non-woven fabric, ultra-fine calcium needs to be crushed and graded. Through grinding and classifying, ultra-fine calcium can play a better role in non-woven fabric.
