Structure and abrasion resistance properties of SSB forming fabric in high-speed paper manufacturing
To study the effect of the structure of self-supporting binding(SSB)forming fabrics for high-speed papermaking on their abrasion resistance,we analyzed the mass loss rate of SSB forming fabrics with different parameters(weave pattern,bottom weft diameter,warp and weft yarn density,and insertion method,etc.)under the abrasion test conditions of 500,750,1 000,2 500,and 5 000 cycles.The results show that the abrasion degree of SSB forming fabrics increases with the increase of friction cycles,and the influence of weaving pattern on the abrasion resistance of SSB forming fabrics varies with warp and weft densities.When the warp and weft densities are small,the mass loss rate is the highest with the bottom layer made of 10-variant warp satin pattern,whereas when the warp and weft densities are large,the mass loss rate is the lowest.Under the same conditions,the abrasion resistance of SSB forming fabrics is positively correlated with the bottom weft diameter and the warp and weft densities.The abrasion resistance of the main structure of SSB forming fabrics is better than that of the inserted structure formed by the inserting process.
