Definitions

  • the present invention relates to natural cellulose fibers having an inorganic metal compound therein, and a process for producing such fibers.
  • copper compounds have antibacterial activity and fungicidal activity
  • oxides of zirconium, cerium and the like have ability to absorb ultraviolet rays
  • zirconium oxide and carbide have the nature of releasing heat by absorbing light.
  • the metal compound is admixed with the material for preparing the synthetic fibers, so that the fibers can be given the desired function to a satisfactory extent, whereas the kneading method is in no way applicable to natural fibers such as natural cellulose fibers.
  • heretofore proposed for treating natural cellulose fibers is a method of coating the surface of cellulose fibers with polyurethane or like resin containing a metal compound to cause the fibers to support the metal compound thereon (Examined Japanese Patent Publication HEI 2-10274, etc.), a method of causing cellulose fibers to support thereon the reaction product of a transition metal and tannic acid (Unexamined Japanese Patent Publications HEI 1-292169 and HEI 1-266275, etc.) and the like.
  • these methods are unable to prepare natural cellulose fibers capable of retaining the imparted function for a prolonged period of time.
  • the finished fibers are hard, have a poor hand and are low in washing fastness such that the deodorant properties become halved or lower when the fibers are washed repeatedly about 10 times.
  • the transition metal becomes inevitably released from the fibers, for example, owing to hydrolysis when the fibers are repeatedly washed.
  • the functional fibers afforded by this method are also low in washing fasteness.
  • the deodorant properties become halved or lower if the fibers are repeatedly washed about 10 times.
  • An object of the present invention is to provide natural cellulose fibers capable of retaining for a prolonged period of time functions imparted thereto by various metal compounds.
  • Another object of the invention is to provide a process for producing such natural cellulose fibers.
  • the present invention provides a natural cellulose fiber having a water-insoluble inorganic metal compound incorporated therein and having at least one heat-treated polycarboxylic acid combined therewith, the polycarboxylic acid being selected from the group consisting of polycarboxylic acids and partial salts thereof. It also provides a process for producing a natural cellulose fiber having a water-insoluble inorganic metal compound incorporated therein, the process comprising the steps of impregnating a natural cellulose fiber with a treating solution containing a water-soluble inorganic metal compound and a polycarboxylic acid, heating the fiber and insolubilizing the water-soluble inorganic metal compound incorporated in the fiber.
  • the natural cellulose fiber of the present invention is characterized in that the cellulose fiber has an inorganic metal compound incorporated therein.
  • fibers are coated with a resin containing a particulate metal compound admixed therewith, or a third substance, such as tannic acid, which is adsorbable by or reactive with fibers and which is caused to form a complex with a metal ion, hence the necessity of using an intermediary substance.
  • the present invention does not require any support medium such as resin or other chemical substance because the natural cellulose fiber has incorporated therein an insoluble metal compound as converted from a metal ion within the fiber.
  • the metal compound incorporating cellulose fiber of the present invention is less likely to release the metal compound even when repeatedly washed. The metal compound is not merely deposited on the cellulose fiber but behaves as if enclosed in the noncrystalline structure of the fiber.
  • Examples of natural cellulose fibers for use in the present invention are cotton and hemp fibers. Such fibers may be in the form of a blend with polyester or like synthetic fibers. The fibers are not limited specifically in form but can be in any form such as yarns, woven fabrics, knitted fabrics or nonwoven fabrics.
  • the inorganic metal compound to be incorporated into cellulose fibers is not limited specifically insofar as it is insoluble in water.
  • useful inorganic metal compounds are hydroxides, carbonates, phosphates, silicates, aluminates and zirconates of metals such as copper, silver, zinc zirconium iron, cobalt, nickel, manganese, cerium, magnesium tin and antimony. At least one of these metal compounds is incorporated into the cellulose fiber.
  • 0.01 to 10 wt. %, preferably 0.1 to 5 wt. %, of the metal compound is incorporated in the cellulose fiber.
  • the natural cellulose fiber of the present invention is produced by causing a metal ion to penetrate into a natural cellulose fiber and converting the metal ion to a water-insoluble inorganic metal compound.

  • the particulars of the process differ as will be described below.
  • the process generally comprises a first bath treatment for impregnating the cellulose fiber to be treated with a water-soluble metal salt and a second bath treatment for insolubilizing the water-soluble metal salt in the fiber.
  • the fiber is treated with an aqueous solution of the water-soluble metal salt so as to be impregnated with the metal salt.
  • the fiber is treated with the metal salt solution, for example, by dipping, padding, spraying or coating.
  • the dipping or padding method is suitable to practice.
  • the dipping method is practiced by dipping the fiber in an aqueous solution containing the metal salt in an amount of 0.01 to 10 wt. % calculated as the metal concerned at room temperature to 100°C for 3 seconds to 10 minutes.
  • the treatment conditions differ with the kind of fiber, and optimum conditions for the fiber to be treated are used.
  • the fiber While the dipped fiber is subjected to the second bath treatment, the fiber may be washed with water and dried before the second bath treatment. Since the metal salt is soluble in water according to the invention, it is desired that the dipping treatment be changed over to the second bath treatment by way of the drying step only.
  • the padding method is especially suited to woven fabrics and knitted fabrics. Stated more specifically when the padding method is resorted to, the fiber is treated as immersed in an aqueous solution containing the metal salt in an amount of 0.01 to 10 wt. % calculated as the metal at room temperature to 100°C for 3 seconds to 10 minutes, and is thereafter squeezed as by a mangle to a predetermined uniform ratio. This treatment is conducted under conditions optimum for the fiber and suitably selected.
  • the padded fiber may be washed with water and dried prior to the second bath treatment to be subsequently conducted. Like the dipping method, the padding method is preferably followed by the drying step only before the second bath treatment.
  • an aqueous solution of alkali, acid or alkali metal salt is caused to act on the water-soluble metal salt impregnating the fiber or deposited thereon to convert the water-soluble metal salt to a water-insoluble metal compound.
  • This treatment can be carried out also by dipping, padding, spraying, coating or like method.
  • the dipping or padding method is suitable to practice.
  • the dipping method is usable for fibers of any form, while the padding method is suited to woven or knitted fabrics.
  • the padding method is practiced by dipping the fiber subjected to the first bath treatment in an aqueous solution containing 0.01 to 10 wt. % of an alkali, acid or alkali metal salt at room temperature to 70°C for 3 seconds to 5 minutes, and thereafter squeezing the dipped fiber as by a mangle to a predetermined uniform ratio.
  • the treatment is conducted under suitably selected conditions which are optimum for the fiber.
  • the padded and squeezed fiber is then soaped or washed with water to completely remove the alkali, acid or alkali metal salt, and is thereafter dried, whereby a natural cellulose fiber of the invention is prepared which has a water-insoluble inorganic metal compound incorporated therein as if enclosed in the amorphous region of the fiber.
  • the metal of the metal compound to be incorporated into the fiber is a transition metal, such as copper, silver, iron, cobalt, nickel, manganese, zinc, titanium, zirconium, cerium, vanadium, molybdenum or tungsten, germanium, aluminum or magnesium
  • the water-soluble metal salt present in the first bath is preferably in the form of the chloride, oxychloride, sulfate, nitrate or like mineral acid salt of the metal, or the acetate, formate or like organic acid salt of the metal, while an aqueous solution of alkali is used as the second bath.
  • useful alkalis are hydroxides of alkali metals, hydroxides of alkaline earth metals, ammonium hydroxide and the like, among which sodium hydroxide is preferred.
  • the metal of the metal compound to be incorporated into the fiber is an metal element such as zinc, titanium, zirconium, vanadium, molybdenum, tungsten, aluminum, silicon, tin or antimony
  • an aqueous solution which contains as an anion the oxide of the metal element prepared by dissolving the element or a salt thereof with an alkali hydroxide or ammonium hydroxide, and to use an aqueous solution of acid as the second bath.
  • useful acids are hydrochloric acid, sulfuric acid and like mineral acids, formic acid, acetic acid and like water-soluble organic acids, etc., among which acetic acid is desirable.
  • the natural cellulose fiber to be treated can be impregnated with a water-soluble metal salt using the first bath and thereafter passed through an aqueous solution of another water-soluble metal salt serving as the second bath to form a water-insoluble inorganic metal salt in the fiber.
  • the water-soluble metal salt for use in the first bath is any water-soluble metal salt other than the salts of alkali metals.
  • the water-soluble metal salt for use in the second bath is any inorganic metal salt which becomes insoluble in water when reacting with the metal salt of the first bath.
  • salts examples include alkali salts of carbonic acid, phosphoric acid, pyrophosphoric acid, metasilicic acid, silicic acid, zincic acid, aluminic acid, titanic acid, molybdic acid, vanadic acid, zirconic acid and the like, alkali sulfides, etc.
  • the metal compound incorporated in the fiber imparts to the fiber deodorizing, antibacterial and fungicidal effects when the compound is, for example, a zinc or copper compound, a deodorizing effect when the compound is an aluminum or magnesium compound, effects to accumulate heat, block ultraviolet rays and radiate far infrared rays when the compound is a zirconium compound, or flame retardant effect when the compound is an antimony compound.
  • An enhanced deodorant effect is available when at least one member selected from polycarboxylic acids and partial salts thereof is used in combination with the water-soluble inorganic metal compound.
  • partial salt of polycarboxylic acid used herein refers to a salt thereof having at least one free carboxyl group remaining after the reaction of all carboxyl groups with a base.
  • polycarboxylic acids are straight-chain or branched-chain aliphatic polycarboxylic acids, alicyclic polycarboxylic acids, aromatic polycarboxylic acids, etc. These acids may be those having a hydroxyl group, halogen atom, carbonyl group or carbon-carbon double bond.

  • the polycarboxylic acid or partial salt is impregnated into and deposited on the cellulose fiber together with the water-soluble metal compound and heat-treated and then the water-soluble metal compound is insolubilized, or alternatively the water-soluble metal compound is insolublized first and the treated cellulose fiber is dipped in an aqueous solution of polycarboxylic acid or the like, followed by heat treatment.
  • the present invention provides natural cellulose fibers capable of retaining for a prolonged period of time the functions imparted thereto by various metal compounds.
