Abstract: A thermoplastic polyurethane composition includes a first thermoplastic polyurethane compound and a modifier formed by subjecting a modifier-forming mixture to a thermal mixing process. The modifier-forming mixture includes a second thermoplastic polyurethane compound, a copolyester modifying agent, and a compatibilizer. The copolyester modifying agent is present in an amount ranging from 5 wt % to 30 wt %, and the compatibilizer is present in an amount ranging from 0.5 wt % to 5 wt %, based on a total weight of the thermoplastic polyurethane composition. A dyeable fiber made from and a method for preparing the thermoplastic polyurethane composition are also disclosed.

Abstract: A polypropylene composition for a dyeable polypropylene filament yarn includes a polypropylene having a melt flow rate ranging from 30 g/10 min to 40 g/10 min, a polyester serving to modify the polypropylene and having a melt flow rate ranging from 40 g/10 min to 50 g/10 min, and a compatibilizer serving to improve compatibility between the polypropylene and the polyester. The polypropylene composition has a melt flow rate ranging from 30 g/10 min to 40 g/10 min.

Abstract: A search method and an electronic device using the method are provided. The search method includes: receiving an input string; determining whether the input string corresponds to a predetermined rule stored in the electronic device; if yes, analyzing the input string into at least a first key string and a second key string according to the predetermined rule; and initiating a searching of the second key string through the network according to a predetermined condition related to the first key string. The electronic device includes a rule module for storing or reading the predetermined rule and a search system for searching through a network by the search method.

Abstract: A level vail includes a pair of elongated tubes, each having a top open end and a bottom open end. A pipe has two ends, respectively connected to the bottom ends of the elongated tubes. Water is contained in each of the elongated tubes, in each of which a floating article is also provided. A communicating member is provided on the top open end of each of the elongated tubes. One communicating member has at least one passage which communicate the interior of the elongated tube and the external atmsophere. A blocking member is movably disposed in the communicating member so that the passage of the communicating member can be opened and closed selectively.
