摘要:
A processing agent containing five specified kinds of components including esters and ethers as required components is used in the production or fabrication process of synthetic fibers such that superior spinning property is maintained and synthetic fibers with superior yam quality and dyeing property can be obtained. Aqueous liquids of such processing agents, processing methods using such liquids and synthetic fibers obtained by such methods are also presented.

The invention relates to a method for the production of a cooling lubricant emulsion mixed with water, used for metal cutting, whereby a) 2-15 parts by weight of a water-miscible concentrate of a coolling lubricant emulsion are mixed with 98-85 parts by weight of water, so as to obtain a mixture comprising 100 parts by weight, and then b) one disperses 1-14 parts by weight of a non water-miscible native-based cutting oil are dispersed, with strong shearing action into mixture a). The cutting oil is preferably chosen from oxidation-stabilized fatty acid glycerides in the form of triesters with three fatty acids with 14-22 C-atoms per fatty acid, and oxidation-stabilized diesters with two fatty acids with 12-22 C-atoms per fatty acid. The invention further concerns a cooling lubricant emulsion that can be produced by this method, and its use for metal cutting.

The present invention relates to a method of and a corresponding system for reducing fuel consumption and environmental impact in a two-stroke engine, comprising the steps of obtaining system oil/consumable system oil (301') from at least one engine (300), adding (102) at least one friction modifier (101) to at least a part of the obtained system oil/consumable system oil (301'), where the addition of the at least one friction modifier (101) reduces the friction coefficient of the obtained system oil/consumable system oil (301'), resulting in a system oil/consumable system oil with reduced friction (301"), and supplying said system oil/consumable system oil with reduced friction (301") to said at least one engine (300). In this way, frictional losses caused by contamination of the system oil/consumable system oil are avoided or minimised, which normally take place as the oil is used and which would otherwise cause a continuous decrease in engine efficiency resulting in increased fuel consumption and emissions. In addition, the present invention related to a method and a corresponding system to convert system oil/consumable system oil into cylinder oil. Finally, the present invention relates to a method to use a consumable system oil as it is being converted into cylinder oil. This furthermore allows for the consumable system oil to contain a lower performance additive package and/or additive treat rate. Thus great economical savings and environmental improvements are achieved.
