Publication number: 20030051834Abstract: The invention is directed to a method of making a heat and light stable carboxylated cellulose fiber whose fiber strength and degree of polymerization is not significantly sacrificed. The method involves the use of a catalytic amount of a hindered cyclic oxammonium salt as a primary oxidant and a peracid and halide salt as a secondary oxidant in an aqueous environment. The oxammonium compounds may be formed in situ from their corresponding amine, hydroxylamine, and nitroxyl compounds. The oxidized cellulose is then stabilized against D.P. loss and color reversion by further treatment with an oxidant such as sodium chlorite, a chlorine dioxide/hydrogen peroxide mixture, or a peracid under acidic conditions. Alternatively it may be treated with a reducing agent such as sodium borohydride. The method results in a high percentage of carboxyl groups located at the fiber surface. The product is especially useful as a papermaking fiber where it contributes strength and has a higher attraction for cationic additives.Type: ApplicationFiled: June 6, 2001Publication date: March 20, 2003Inventors: S.

Patent number: 6464730Abstract: The present invention is generally directed to a process for making fabrics containing cotton fibers more aesthetically pleasing and resistant to staining by anionic dyes by derivatizing the cotton so that it exhibits a permanent anionic charge. By increasing the anionic charge of the fibers, the fibers become resistant to anionic coloring agents which may undesirably come into contact with the fibers and the fibers can absorb greater amounts of cationic softeners and biocides. Furthermore, the negative charges repel each other resulting in a fabric with greater loft and hydrophilicity. This results in greater smoothness, better hand, and more comfort. Besides being used to prevent the cross-staining of fabrics, the present invention can also be used to make carpet materials resistant to anionic staining agents.Type: GrantFiled: June 9, 2000Date of Patent: October 15, 2002Assignee: Sybron Chemicals, Inc.Inventors: Robert B.

Patent number: 5879410Abstract: A process for resin finishing textile containing cellulosic fiber comprises the steps of using a resin finishing agent chiefly containing a cellulose-reactive N-methylol compound having two or more functional groups and a reaction catalyst, mainly reacting only one functional group of the cellulose-reactive N-methylol compound with cellulose, water washing, again imparting reaction catalyst, drying, garment making, and heat treating. The process eliminates the conventional postcuring method drawbacks of loss of color fastness and discoloration owing to dye decomposition and formaldehyde increase by unreacted resin and residual reaction catalyst during long storage before heat treatment, and simultaneously achieves high crease-resistant property, shrink resistance, good feeling, excellent pleating property, and anti-puckering property.Type: GrantFiled: December 12, 1997Date of Patent: March 9, 1999Assignee: Nisshinbo Industries, Inc.Inventors: Yuichi Yanai, Masayoshi Oba, Yasushi Takagi, Tadashi Isogai

Patent number: 5856246Abstract: The invention concerns a thin film of a permanent hydrophobic and optionally oleophobic finish for polymer surfaces. The film is formed from at least one layer of a water-soluble polycation and cationic synthetic resin. For further improvement of the oleophobic and permanent hydrophobic properties the film can additionally contain a long-chain surfactant or an alkyl-substituted polyanion.Type: GrantFiled: March 26, 1997Date of Patent: January 5, 1999Inventors: Richard Witzko, Wolfgang Burger, Gudrun Petzold, Klaus Lunkwitz, Heide-Marie Buchhammer

Patent number: 5824115Abstract: A cellulose fiber is immersed in a cellulose fiber dissolving agent such as tertiary amine-N-oxide, lithium chloride/N,N-dimethylacetoamide or N-methylmorpholine-N-oxide under conditions where the dissolving agent does not dissolve the cellulose fiber. Therefore, the water absorbing property and moisture absorbing and discharging property of the cellulose fiber can be improved without deteriorating the strength and feeling of the cellulose fiber.Type: GrantFiled: November 27, 1996Date of Patent: October 20, 1998Assignee: Kao CorporationInventors: Yuichi Kubota, Eiichi Hoshino, Koji Aigami

Patent number: 5807956Abstract: The present invention discloses non-hydrolyzable, block, (AB).sub.n A type, copolymers comprising alternating units of polysiloxane and amino-polyalkyleneoxide and provides a method for the preparation of these copolymers. Also provided is the use of these copolymers as softeners, in particular durable, hydrophilic textile softeners, which improve tactile properties of the textiles substrates treated with the commercial soil release finishes, without substantially detracting from their properties.The copolymers of the present invention have alternating units of polysiloxane ?X(C.sub.a H.sub.2a O).sub.b R.sup.2 ?(SiO(R.sup.1).sub.2 !.sub.c Si(R.sup.1).sub.2 R.sup.2 (C.sub.a H.sub.2a O).sub.b X!and polyalkyleneoxides ?YO(C.sub.a H.sub.2a O).sub.d Y!wherein R.sup.1 is a C.sub.1 to C.sub.4 alkyl, preferably methyl, R.sup.Type: GrantFiled: March 4, 1997Date of Patent: September 15, 1998Assignee: OSi Specialties, Inc.Inventor: Anna Czech
