Abstract: This invention discloses a fiber filament having ultraviolet ray hiding effect and fabric manufactured from said filament. The ultraviolet ray hiding effect of this invention is obtained by adding inorganic titanium dioxide particles having average diameter of less than 100 nm and constituting preferably less than 1 weight % of the total fiber. When fiber filaments of this invention are used in fabric production they constitute preferably over 50% weight of the fabric. thereby producing a fabric with opening rate preferably in excess of 0.7% but preferably less than 25%. The Ultraviolet Protective Factor (UPF) of said fabric is preferably over 40%.

Abstract: This invention discloses a novel, polyester-resin composition containing CaCO3 having inter-bottle friction reduction properties used to manufacture polyester bottles. The polyester resin composition contains preferably between 20-150 ppm CaCO3, which has a reflective index or refrangibility of 1.65, and particle grain size of preferably between 0.5 and 5 micrometers. The polyester/CaCO3 composition of this invention when used to manufacture polyester bottles reduces surface friction between polyester bottles during stacking, manufacturing transportation and commercial transportation while preserving acceptable commercial bottle transparency. The polyester-resin composition of this invention is first made into parison and then blown molded into polyester bottles of desired shapes.

Abstract: The present invention provides and relative equipment to eliminate formic acid and acetic acid from process water in ethylene glycol plant. First, we use weakly basic anion resin to absorb the weakly acidic ions of formic acid and acetic acid. The rest free ions then will be absorbed by strongly basic anion resin. In this invention, we use vertical strataed bed or horizontal series bed as the treating unit, which are packed with weakly basic and strongly basic anion resins. This can increase the efficiency of eliminating formic acid and acetic acid from process water, save cost, and reduce the amount of wastewater.

Abstract: A compressible separator system for packaging yarn spools, having a top plate with face-down support plugs, a bottom plate having face-up support plugs and at least one middle plate having face-up and face-down support plugs. The plates made of single molding construction by plastic forming and the support plugs adapted to secure corresponding yarn spools. The support plugs including plug caps (84, 85) having respective the 1st and 3rd, or the 2nd and 4th are corner-wise symmetric such that in the absence of any other items such as the yarn spools or the tube cores between the plates, the plug caps between the top plate and the middle plate, between at least two said middle plates, between the middle plate and the bottom plate, or between the top plate and the bottom plate may be inserted into corresponding open quadrants of one another to form a rigidly stacked structure. The plug caps may be of different sizes.

Abstract: The present invention is related to a process of manufacturing polyproylene (PP) synthetic paper and the product thereof, and particularly to a process of manufacturing synthetic paper by means of 3-layer co-extrusion wherein PP resin composite and resin composite are respectively extruded as an extrudate co-flow by one primary extruder and two secondary extruders and by same one T-type die to be a paper sheet with a paper surface layer, an intermediate layer and a paper surface layer, and through cooling/shaping, biaxial orientation, corona discharge treatment and laminating/rolling to be a synthetic paper depending on the required thickness.
