Felt warp and weft break: Usually caused by the damage of hard objects; Sometimes the pulp bolts may made holes on the felt; Sometimes the fine hard objects such as sand, broken glass in yhe pulp will make the felt strength decline, the felt warp and weft break; Flakes or punctate appeared in felt, warp and weft broken, may be caused by chemical corrosion, which is low fiber strength. Edge warp break, mostly due to the felt is too wide, caused by friction with the rack.
