An active material support in a polar plate for a lead storage battery is provided to improve the battery performance by virtue of excellent hygroscopicity and electrolyte-retention and to increase the workability and productivity by virtue of superior mechanical properties, as well as to prolong the life of battery. The active material support(5) in a polar plate(1,2) for a lead storage battery(3) is formed of a fabric which is woven with warps and wefts of hydrophilic shaped yarns. Preferably, in the fabric, the hydrophilic shaped yarns comprise at least 10 wt% of a hydrophilic resin. The hydrophilic shaped yarns have a cross-section having a 3-8 angled polygonal shape or a clover shape with 3-8 protuberances. The fabric has a texture of 5-16 leaf twill or 5-16 leaf satin. |
