Abstract: The present invention provides an agent for treating textile having a combination of a modifying agent and a fixing agent, wherein the modifying agent is a fluorine-containing phosphoric acid derivative represented by the formula wherein R.sup.1 and R.sup.2 are, same or different, a hydrogen atom or R.sub.f --(CH).sub.2).sub.m -- (wherein R.sub.f is a saturated or unsaturated, linear or branched fluorine containing aliphatic group having 4 to 20 carbon atoms in which an oxygen atom, a nitrogen atom, a sulfonyl group and/or an aromatic ring may intervene between the carbon atoms; and m is 1 or 2) (R.sup.1 and R.sup.

Abstract: A textile treatment agent which contains, as an active component, a graft fluorocopolymer having a backbone of a polymer of a fluoromonomer and a branch of a polymer of a fluorine-free macromonomer prepared by copolymerizing the fluoromonomer with the macromonomer which is a fluorine-free macromonomer having addition-polymerizable unsaturated group at a molecular end gives excellent water- and oil-repellency and stainproof property.

Abstract: A water- and oil-repellent fiber formed from a synthetic resin composition which contains a fluorine-containing polymer having a repeating unit (a) having a perfluoroalkyl or perfluoroalkenyl group and an ether linkage gives a fabric having excellent water- and oil-repellency, excellent stain resistance and excellent feeling.

Abstract: A hologram surface to express a phase distribution, a visual field in which a solid image can be seen; and a stereoscopic display limit are set in a virtual space. A target to be stereoscopically displayed is subsequently expressed in the virtual space by a set of micro polygons. A plurality of slice planes which are parallel with the horizontal plane are set into the virtual space including the target. The line segments which intersect the polygons are obtained for every slice plane. The detected line segment is divided or clipped as necessary and is finally divided into the portion which can be always seen from the whole region of the visual field and a portion which is obstructed by another line segment and can be seen from only a part of the visual field, thereby extracting the line segment.

Abstract: A biodegradable film or the like shaped article is formed from a composition including 100 parts by weight of cellulose fibers having a length of 3 mm or less and a diameter of 50 .mu.m or less, 10-600 parts by weight of a thermoplastic resin and 2-100 parts by weight of chitosan. A mixture containing (a) an aqueous solution of an acid salt of chitosan, (b) an aqueous dispersion or solution of a thermoplastic resin and (c) fine cellulose fibers is dried and shaped to obtain such a biodegradable shaped article.

Abstract: A biodegradable sheet is produced from an aqueous dispersion containing finely cut cellulose fibers and chitosan. The dispersion is maintained at a temperature T.sub.1 .degree.C. which is within the following range:t.ltoreq.T.sub.1 .ltoreq.t+30wherein t is the boiling point (.degree.C.) of water at a given reduced pressure and is continuously introduced into a defoaming zone maintained at the given reduced pressure and at a temperature within the same range as that of T.sub.1. In the defoaming zone, the dispersion is formed into a downwardly flowing laminar flow so that air entrapped therein is effectively removed therefrom. The defoamed dispersion is then passed through a die and is molded into a sheet which is subsequently dried.

Abstract: A copolymer comprising (a) an acrylate or methacrylate having a fluoroalkyl group, (b) a polyalkylene glycol acrylate or methacrylate, (c) an acrylate or methacrylate having a hydroxyl group, and (d) at least one compound selected from the group consisting of alkyl acrylates, alkyl methacrylates and butadiene, which can impart durable water- and oil- repellency and soil-releasability to fabrics.

Abstract: This invention provides an antifouling finishing agent comprising a fluorine-containing polymer comprising at least 50% by weight of a fluorine-containing acrylate represented by the formula ##STR1## wherein Y is alkylene group having 1 to 3 carbon atoms, a group of the formula --CH.sub.2 CH.sub.2 N(R)SO.sub.2 -- (wherein R is alkyl group having 1 to 4 carbon atoms) or a group of the formula --CH.sub.2 CH(OZ)CH.sub.2 -- (wherein Z is hydrogen atom or acetyl group), and R.sub.f is fluoroalkyl group having 3 to 21 carbon atoms or fluoralkyl group having 3 to 21 carbon atoms and containing 1 to 10 oxygen atoms in the carbon chain (provided that no oxygen atom is adjacent or closest to other oxygen atom), said fluoroalkyl groups having at least 5 fluorine atoms.
