An oil-soluble polyester having a weight average molecular weight of 10,000 to 1,000,000, which is a polycondensate prepared by polycondensing the following ingredients (A) and (B): (A) a dicarboxylic acid ingredient, and (B) a diol ingredient comprising (i) a hindered glycol represented by the following formula: HO--CH.sub.2 --CR.sup.1 R.sup.2 --CH.sub.2 --OH wherein R.sup.1 and R.sup.2 independently represent a linear or branched alkyl group, and (ii) an alkylene glycol having at least 4 carbon atoms in the main chain. This oil-soluble polyester is useful as an additive for a lubricating oil.

An oil-soluble polyester having a weight average molecular weight of 10,000 to 1 000,000, which is a polycondensate prepared by polycondensing the following ingredients (A), (B) and (C): (A) a divalent higher carboxylic acid ingredient, (B) a divalent alcohol ingredient comprising a glycol represented by the following formula: HO--CH.sub.2 --CR.sup.1 R.sup.2 --CH.sub.2 --OH wherein R.sup.1 and R.sup.2 represent a alkyl group, and the sum of carbon numbers in R.sup.1 and R.sup.2 is at least three, and (C) 0.1 to 15% by mole, based on the total of ingredients (A) and (B), of at least one multi-valent ingredient selected from a carboxylic acid with a valency of at least three and an alcohol with a valency of at least three. This oil-soluble polyester is useful as an additive for a lubricating oil.

In order to achieve both ease of removal and an increase in the rate of impregnation by a predetermined chemical, in this packaging structure of a package of wet wipes, a convex region is formed at a position containing a region that faces the opening of a main package body and that is on the upper surface of a stacked body of wet wipes. The convex region is formed protruding towards the main package body. A space is formed between the region (corresponding to the ends) aside from the convex region formed on the wet wipes and the upper surface to which the opening of the main package body is provided.
摘要:
This method for producing wet wipes includes the following steps: a step for vertically folding non-woven cloth sheets; a step for impregnating the sheets with a chemical; a step for stacking the sheets; a step for cutting the sheets at predetermined lengths; a step for pulling the cut sheets away from a transporting conveyer provided with a suction mechanism by means of a pusher, and stacking the cut sheets; a step for pressing a bundle comprising the sheets; and a step for packaging the bundle. The pusher is disposed between the transporting conveyers. The blades of the pusher have a plurality of tooth sections. The pusher drops the sheets suctioned to the transporting conveyer downwards by means of moving vertically downwards.

摘要:
The present invention prevents unevenness in the amount of impregnation by a predetermined chemical and prevents a decrease in ease of removal resulting from increasing the rate of impregnation by the predetermined chemical. A press device (15) has: a plurality of rollers (201, 202, 203); press belts (204a, 204b) wound around the plurality of rollers (201, 202, 203); and conveyor belts (205, 206) that convey a stacked body (800). At least one roller from among the plurality of rollers (201, 202, 203) drives the press belts (204a, 204b) at a predetermined speed of conveyance and in a predetermined direction of conveyance. The press belts (204a, 204b) are disposed with a gap in an intersecting direction (CD) perpendicular to the conveyance direction (MD) that is such that the press belts (204a, 204b) can contact both end portions (800A, 800B) of the stacked body (800) in the intersecting direction (CD).
