Abstract
Disclosed is a lithium ion secondary battery, which comprises a vinyl alcohol polymer or a derivative thereof in an amount of 0.3 mg or more per 1 mAh of battery capacity in terms of a vinyl alcohol unit moiety content. The lithium ion secondary battery can decrease the battery voltage under high-temperature conditions and cannot be recharged after being exposed to high-temperature conditions.
A separator for alkaline batteries which comprises both a fusion-bonded fiber layer and an ultrafine-denier fiber layer which is adjacent to the fusion-bonded fiber layer and comprises both ultrafine-denier fibers and second fusion-bonded fibers, wherein part of the ultrafine-denier fibers are incorporated into the fusion-bonded fiber layer, so that in determining the interlaminar strength between the fusion-bonded fiber layer and the ultrafine-denier fiber layer, delamination occurs in the ultrafine-denier fiber layer and therefore the determination results in failure. The separator can be produced by a process which comprises the step of producing a fusion-bonded fiber sheet, the step of preparing a slurry containing ultrafine-denier fibers and second fusible fibers, the step of applying the slurry onto the fusion-bonded fiber sheet by papermaking method to make part of the ultrafine-denier fibers enter the fusion-bonded fiber sheet, and the step of fusion-bonding the second fusible fibers present on the sheet. The separator is excellent in denseness and strength even when it is thin, and can give alkaline batteries having low electric resistance, while the above process is excellent in productivity.
A weather strip is mounted at the peripheral part of a door opening of a door for an automobile. The weather strip includes a sectionally nearly U-shaped trim part and a hollow seal part. A design lip is extended out from the trim part. A decoration layer of a non-woven fabric is formed on the design surface of the weather strip such as the outer surface of the design lip through a resin bonding layer of polyethylene (PE). The non-woven fabric constituting the decoration layer contains fibers subjected to “crimping processing” and has predetermined elasticity (stretch of 5 mm or more when load of 20 N is applied).
