Abstract: The present invention discloses a free-cut warp-knitted elastic fabric with a hidden cross stripe and a method for knitting thereof. The method includes: making a non-elastic yarn pass across a guide needle of the first guide bar and form the surface of the fabric by knitting via three needles in an open warp sateen loop mode, and making an elastic yarn pass across a guide needle of the second guide bar and form the inside of the fabric by knitting with the aforementioned non-elastic yarn in the same direction via three needles in an open warp sateen loop mode. The warp-knitted fabric provided by the present invention can be arbitrarily cut, does not ravel easily, is free of hemming-stitch, and has a hidden cross stripe effect.

Abstract: The present invention provides a free-cut warp-knitted elastic fabric and a method for production thereof. The method uses a first guide bar and a second guide bar of a tricot warp knitting machine for knitting, wherein a non-elastic yarn passes across a guide needle of the first guide bar and forms the surface of the fabric by knitting via two needles in a 1×1 warp plain stitch loop mode, and an elastic yarn passes across a guide needle of the second guide bar and forms the inside of the fabric by knitting with the aforementioned non-elastic yarn in the same direction via two needles in a 1×1 double warp plain stitch loop mode. Finally the fabric which has good resilience, can be arbitrarily cut, and has low raveling property, good elasticity and high snagging level is obtained.

Abstract: This invention relates generally to inorganic ionic liquids which function as electrolytes and do not crystallize at ambient temperature. More specifically, this invention is directed to quasi-salt inorganic ionic liquids which comprise the reaction product of a strong Lewis acid with an inorganic halide-donating molecule. This invention is further directed to quasi-salt inorganic ionic liquid mixtures which comprise combinations of electrolyte additives and quasi-salt inorganic ionic liquids. These quasi-salt inorganic ionic liquid mixtures are useful electrolytes.

Abstract: The present invention relates to electrolyte solvents for use in liquid or rubbery electrolyte solutions. Specifically, this invention is directed to boron-containing electrolyte solvents and boron-containing electrolyte solutions.

Abstract: This invention relates generally to electrolyte solvents for use in liquid or rubbery polymer electrolyte solutions as are used, for example, in electrochemical devices. More specifically, this invention relates to sulfonyl/phospho-compound electrolyte solvents and sulfonyl/phospho-compound electrolyte solutions incorporating such solvents.
