Claims12
A holding sealer for holding an exhaust gas processing device, comprising:
- a sheet member including interwoven inorganic fibers and having an upper side and a lower side,
- a plurality of discrete needling process traces existing in both of the upper and lower sides of the sheet member and being alternately arranged between the upper side and the lower side of the sheet member, each needling process trace being oriented in a predetermined angle between 5° and 85° with respect to a direction of a thickness of the sheet member, wherein the interwoven inorganic fibers are locally oriented in the predetermined angle along the needling process traces included within the sheet member and the oriented angle of the inorganic fibers with respect to the direction of the thickness of the sheet member is between about 45° and 75°.
An exhaust gas processing device comprising:
- a metallic shell including an exhaust gas processing body and a holding sealer wound around at least a portion of outer surfaces of the exhaust gas processing body, wherein the holding sealer comprises:
- a sheet member including interwoven inorganic fibers and having an upper side and a lower side, and
- a plurality of discrete needling process traces existing in both of the upper and lower sides of the sheet member and being oriented in a predetermined angle between 5° and 85° with respect to a direction of a thickness of the sheet member, wherein the interwoven inorganic fibers are locally oriented in the predetermined angle along the needling process traces included within the sheet member and alternately arranged between the upper side and the lower side of the sheet member and the oriented angle of the inorganic fibers with respect to the direction of the thickness of the sheet member is between about 45° and 75°.
