Definitions

  • the present invention relates to ceramic-containing fiber wherein characteristic features belonging to finely divided ceramic particles are suitably selected and applied to vegetable fiber without damaging essential characteristic features thereof and a process for preparing the same. More particularly, the invention relates to ceramic-containing fiber which can maintain the above described characteristic features for a long period of time and an easy process for preparing the same which comprises immersing fiber in a prescribed processing solution which has been heated and pressurized, and solid-dissolving finely divided ceramic particles into minute pores involved in the resulting swelled monofilaments of said fiber.
  • cotton which is one of vegetable fiber is most widely used in the world as fiber for clothing, and the production thereof holds a majority of the whole fiber for clothing.
  • Such a cotton fiber is produced as a result of gradually long and narrow growth of an epidermal cell of a cotton seed, so that a vestige of protoplasm remains as a vacuole at the central portion of a sufficiently matured cotton fiber.
  • Cotton fiber which had been reaped becomes flat and intertwined as a result of drying the same.
  • cotton fiber having such characteristic features involves said vacuole, then it results in favourable heat retaining property and touch, whilst such twist makes intense intertwinment among fibers to effect favourable spinning. Accordingly, cotton possesses very good properties as fiber for clothing.
  • synthetic fiber exhibits beautiful appearance peculiar thereto, moderate elasticity and strength while satisfying a demand corresponding to consumption of such synthetic fiber.
  • the characteristic features of the very high-molecular weight material are actualized so that essential characteristic features such as heat retaining property and hygroscopic property belonging to cotton fiber are damaged.
  • minute pores involved in vegetable fiber are allowed to swell by the use of an organic solvent or an aqueous solvent, and then the fiber is immersed in a prescribed processing solution which has been heated and pressurized, and ceramic fine particles are caused to exist among minute pores involved in the swollen monofilament fiber.
  • characteristic features such as heat insulating properties, water absorption properties and the like involved in ceramic fine particles are suitably selected therefrom and added to those of fiber in question without damaging characteristic features which have been involved therein originally.
  • the fiber containing the above described characteristic features improved may be manufactured by a simple manner.
  • a cotton fiber has a vacuole in its cross section so that it makes heat retaining property and touch of the fiber better, besides twist in monofilament makes intense intertwinment among such monofilaments.
  • arrangement of crystallite of monofilament is spiral along major axis of fiber on which minute pores appear in turned and twisted form.
  • the present invention utilizes such characteristic features as described above.
  • said minute pores are filled with ceramic finely divided particles, said minute pores existing as its non-crystalline region in a crystalline region where an arrangement of crystallite which forms said monofilament is regular and the non-crystalline region where the arrangement is irregular.
  • the minute pore has a size of 5 - 10 angstrom
  • a diameter of the pore expands to 40 - 100 angstrom.
  • the fiber can be filled with ceramic finely divided particles having an average particle diameter of 60 angstrom using with this invention.
  • dinitrogen tetroxide is allowed to contain in an organic solvent such as dimetylformamide, N-methyl-2-pyrrolidone and the like, or cotton fiber is subjected to swell by the use of an aqueous solvent such as aqueous cupricammnium, aqueous alkali and the like which is commonly known in a cylindrical form.
  • organic solvent such as dimetylformamide, N-methyl-2-pyrrolidone and the like
  • cotton fiber is subjected to swell by the use of an aqueous solvent such as aqueous cupricammnium, aqueous alkali and the like which is commonly known in a cylindrical form.
  • Either the cotton fiber swelled is filled with ceramic in water, or the cotton fiber swelled is subjected to liquid current treatment in a sealed pressure vessel containing aqueous solution involving said solvent or aqueous solvent to which is added ceramic having an average particle diameter of 60 angstrom at a temperature of from 90 to 110 C under a pressure of from 4 to 6 kg/cm .
  • cotton fiber to be processed when a dyestuff or a bleaching agent is added to a processing solution in said sealed vessel, cotton fiber to be processed can be bleached or dyed at the same time of filling the cotton fiber with ceramic.
  • the resulting cotton fiber contains a ceramic having a very high porosity (e.g. 90% or more) as a result of solid solution of ceramic, such cotton fiber is excellent in heat insulating property. More specifically, a thread containing a solid such as porous silica ceramic of the present invention and gas does not only make small the heat transfer by conduction which propagates through the fiber itself, but also heat transmission between the fiber and the space as well as radiation heat transfer, so that the resulting thread has a very excellent heat insulating property and clothes and the like made from such cotton fiber do not absorb the heat from the outside.
  • a thread containing a solid such as porous silica ceramic of the present invention and gas does not only make small the heat transfer by conduction which propagates through the fiber itself, but also heat transmission between the fiber and the space as well as radiation heat transfer, so that the resulting thread has a very excellent heat insulating property and clothes and the like made from such cotton fiber do not absorb the heat from the outside.
  • a ceramic having a high porosity absorbs easily moisture due to capillary action of the pores so that the resulting cotton fiber is sensitive to hygroscopicity from the outside, and the ceramic existing in the interior of said minute pores absorbs moisture, in turns, the moisture is rapidly absorbed up to a split hole inside the cotton fiber, whereby a moisture content of the cotton fiber itself is elevated.
  • This moisture content functions to adapt to the external atmosphere as a natural characteristic feature of cotton, i.e. when the environment dries, the moisture is released to the surface of the cotton fiber, whereby environmental adaptability is added to characteristic features of cotton.
  • underwear made from the ceramic cotton has superior water absorption properties to those of conventional cotton manufactured goods.
  • ceramic exhibits various characteristic features dependent upon ingredients thereof.
  • translucent ceramic being transparent in infrared region exhibits high selective absorption with respect to infrared rays.
  • a metallic oxide MgO ceramics, Si0 2 ceramics, Al 2 O 3 ceramics or the like
  • an article to be warmed for example, human body and the like
  • far infrared rays 25 - 10 um
  • the ceramic-containing fiber and the process for preparing the same according to the present invention may add characteristic features such as heat insulating absorptive effect, divergent effect as well as filtering effect which are peculiar to ceramic to vegetable fiber which is supplied in a comparatively large amount among natural fiber.
  • the process for the preparation according to the present invention is useful for preparing the fiber having additional characteristic features, and particularly it is suitable for solid-dissolving ceramic finely divided particles in vegetable fiber.

Abstract

On fait gonfler une fibre végétale avec un solvant organique ou aqueux dans une forme cylindrique et on l'immerge ensuite dans une solution aqueuse de traitement contenant de fines particules de céramique, de manière à provoquer la pénétration de ces particules dans les micropores dilatés de la fibre végétale. Ce procédé permet de combiner sélectivement les propriétés de la céramique avec les propriétés inhérentes de la fibre végétale, de manière à obtenir une fibre végétale présentant une excellente stabilité et indiquée pour de nombreuses applications.
