Tearing strength of paper
Webb5 nov. 2024 · This study investigates alternatives that can improve the internal bond strength (IBS) of paper by pulp refining and paper press-drying (PD). The improvement mechanisms of IBS and their impact on the strength development of high-yield pulps are discussed. All experiments were conducted using a factorial design where the factors … WebbA qualitative discussion was made of tearing action—the influence on tear strength of various types of fabric distortion at or near the tear such as yarn pull-out force, crimp, cover factors, and dimensional stability in the plane of the fabric. Then the relationships between these types of distortion and the variable fabric factors were ...
