1. Small fibers have a large specific surface area, low crystallinity, and are more prone to water absorption and swelling compared to fibers, resulting in a high water retention value that can significantly reduce the water filtration performance of paper materials; However, secondary fine fibers are more prone to water absorption and swelling than primary fine fibers, thus having a greater impact on the paper machine's water filtration capacity.

2. Poor water filtration performance of fine fibers can also cause an increase in paper moisture, thereby reducing the speed and output of the paper machine.

3. In terms of performance, small fibers are mainly retained through the aggregation mechanism of colloidal action. And its surface carries negative charges, making it easier to maintain a dispersed state. The low retention rate causes a large amount of fine fibers to enter the white water of the paper machine, which circulates and accumulates with the white water in the system, thereby affecting the cleanliness and operational performance of the paper machine.

4. Fine fibers mainly affect cleanliness and operational performance in three ways;

5. High content of fine fibers can cause deposition of fine fibers and their carriers, such as resin barrier issues;

6. Fine fiber can stabilize foam, interfere with the operation performance of paper machine and affect the quality of paper industry;

7. The effect of fine fibers on the properties of paper;

8. Small fibers affect the properties of paper in two ways: firstly, the direct impact of small fibers themselves on the properties of paper; Secondly, the selective adsorption of small fibers on additives has an impact on the properties of paper pages;
