Definitions

  • My invention relates particularly to an improved process of making paper and other fibrous products and similar materials, as Well as the product thereof which is more resistant to electricity, heat, cold, oils and moisture than paper products heretofore made.
  • the object of my invention is to provide a process of the above character,'and product thereof having the above characteristics, and in which the dielectric is very much higher than in the case of previous paper or fibrous products.
  • Previously attempts have been made to secure somewhat similar properties by applying a coating in the form of a varnish to the paper but the product so produced becomes stifi' and brittle and loses its natural flexibility and resilience.
  • the product made in accordance with my invention has the above desired improved characteristics and at the same time substantially retains the natural flexibility of the fibres.
  • Example 1 may take 1 1b., that is to say 454 grams, of cotton rag fibre which has been thoroughly pulped, and add thereto 22 grams of kelp, that is to say, preferably Laminaria containing both the algin compounds and the algulose reduced to an aqueous solution by the incorporation with the kelp of 2 grams of sodium hydroxide dissolved in 25 cc. of Water. These materials are thoroughly mixed together in a pulp beater so as to produce a homogeneous mass. I then add 16 grams of zinc sulphate dissolved in 200 cc. of water and run the beater until the zinc has become thoroughly distributed through the same. The zinc sulphate acts as a precipitant.
  • the web of paper is now gilt through a supercalender and the paper 'shed in the usual way in the manufacture of paper.
  • the precipitated algin and algulose is compressed into a film through and around the cotton fibres without afiecting the natural flexibility of the fibrous sheet, while the resistance of the product to electricity, heat, cold, oils, moisture, etc., is greatly increased.
  • the dielectric of the product is about 450 bolts per mill. thickness, that is to say at least 40% hi her than in the case of paper Without the ad ition of the kelp.
  • zinc sulphate I may use other metallic salts, lime or mineral acids as a precipitaut.
  • Example 2 In this example of my invention I take 1 1b., that is 454 grams, of cotton rag fibre which has been thoroughly pulped, and add thereto 13 grams of kelp preferably Laminaria containing both the algin compounds and algulose reduce to an aqueous solution by the addition thereto of 1 gram of sodium hydroxide dissolved in 25 cc. of water. To the kelp solution I add 5 grams of raw rubber in the form of latex before the solution is added to the pulp. I thereupon incorporate the resultant solution with the pulp in a pulp heater and then add 18 to 20 grams of calcium acetate dissolved in 200 cc. of water and run the beater until perfect distribution has been obtained to form a homogeneous mass.
  • the calcium acetate acts as a precipitant.
  • the product is then washed and run onto a screen of a paper making machine to make a web which is drieduntil there is only 5% of moisture left. Then the web is passed through a supercalender with hot rolls to finish the paper as above, in the previous example, in accordance with the usual steps followed in the manufacture of paper.
  • the temperature of the hot rolls should be about 240 F.
  • I may use, instead of the'rubber, any other binding material including waxes such as beeswax, resins such as rosin, bituminous substances such as asphalt, and I may use as a filler an inert insoluble material in order to obtain the product desired for the several uses to which it may be applied.
  • any of these binding material and fillers in the first example of my invention above referredto, or, in fact, in any form of my invention, when desired.
  • I may use any of the precipitants as referred to in the first example.
  • any other kind of fibre pulp may be used, such as wood pulp, etc.
  • algulose and rubber are algulose and rubber, and then forming the same into a paper web.
  • the process of making fibrous products which comprises incorporating together fibrous material, a kelp product formed from alginic acid and alkulose, a filler and rubber, and then forming the same into a coherent mass.
  • a paper containing a fibre pulp, a kelp product-formed from kel including its alginic acid and algulose, w 'ch has been solubilized with an alkali and rendered insoluble with a precipitant, and a binding material.
  • a paper containin a fibre pulp, a kelp product formed from ke including its alginic acid and algulose, w 'ch has been solubilized with an alkali and rendered insoluble glilth a precipitant, abinding material and a 20.
  • a fibrous material containing fibre a kelp product formedfrom kelp including its alginic acid and algulose which has been solubilized and then rendered insoluble with a precipitant, and rubber.
